The product, in particular, has a metal and non-metal outer casing having a heat generating component such as a motor, an electronic component, a heater, a battery, and the like, and a surface-treated metal plate which is a material of the outer casing. Further, the present invention relates to a refrigerator having a high heat efficiency using a material excellent in heat absorbing property, a portable device (mobile device) or a 10 vehicle device that applies a high heat absorbing paint to the inside of the casing to suppress an increase in temperature. Its housing. Portable or on-board devices include mobile phones, notebook PCs, PDAs, car battery cases, car navigation systems, car audio equipment, and car control machines. t Previous 3 Background Art 15 In the past, a metal plate such as a steel plate or an aluminum plate was used for the outer casing of the outer panel of the home electric appliance and the inner part, and the metal plate was required to have corrosion resistance, β recalculating property, etc. It will be used after surface treatment. Further, such a metal plate may, for example, be a galvanized steel sheet excellent in corrosion resistance, a galvanized steel sheet covered with chromate, or a precoated metal panel which is precoated and imparted with design. Metal sheets are further required to have properties such as fingerprint resistance, grounding resistance, and processing wear resistance, and in order to satisfy these properties, various surface-treated steel sheets have been developed. For example, Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. The organic composite film is used to increase the corrosion resistance and fingerprint resistance. Further, Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. Further, Japanese Laid-Open Patent Publication No. Hei No. Hei. No. 16128 discloses a technique of imparting fingerprint resistance and grounding by covering a surface of a metal surface subjected to chromate treatment with a thin surface of a controlled surface roughness and film thickness. Furthermore, non-metallic materials such as plastics are also used as the outer casing of the outer panel and the inner casing of the home appliance. However, in this case, also because of the popularity of computers in recent years and the electronicization of home appliances, etc., the inside of such computers and home electric appliances have begun to use many motors and electronic parts as heat source parts, and the heat generation of these heat sources It is also gradually increasing, so that the outer casing of the outer panel of the product and the outer casing of the inner part are also required to have the characteristic of suppressing the heat generated inside, or the property of efficiently dissipating the heat. On the other hand, it is required that the heat generating body of a home electric appliance or the like must have electrical conductivity for grounding. Conventionally, in order to suppress an increase in the temperature inside the electronic device of the built-in electronic component, heat dissipation is considered in consideration of heat dissipation in the electronic component. The sheet and the opening for heat dissipation are provided in the electronic device casing, and the inside of the electronic device is forcedly cooled by a fan or the like. Since the electronic device is not heat-resistant, if the temperature rises, it causes malfunction, and the performance is lowered, so heat dissipation and cooling are very important. Recently, because of the high integration and fine wiring, the development of the towel is becoming more important, and it is more important to reduce the performance such as the malfunction of the invention and the slowing of the operation speed due to the temperature of the 20 1313641 发明. In particular, the self-heating of the heat-generating electronic components and the battery built in the portable electronic device and the mobile device that is used outdoors and exposed to heat from the engine and the like may cause heat accumulation in the casing of the machine. 5 How to suppress the temperature rise of electronic equipment and batteries is a very important issue. In the past, the main technology used for the heat dissipation of the housing of electronic equipment is to form a high-heat opening or to form a casing with a high heat-transfer material. It has also been proposed to coat the outer side of the casing with a highly radioactive 10 coating for improving heat dissipation. A conventional technique similar to the present invention is disclosed in Japanese Laid-Open Patent Publication No. Hei 11-340639. The inner side of the casing of an electronic device including the τνWei machine and other portable information machines is coated with an infrared absorbing agent. The coating is thin. 15 In the cooling and heat dissipation of electronic devices, various methods have been proposed or adopted as described above. However, in portable devices or in-vehicle devices, the material of the housing is often limited for reasons such as aesthetics, lightness, and the like. In order to achieve miniaturization and high performance, more efficient cooling and heat dissipation are required. A first object of the present invention is to develop a technique capable of imparting excellent heat absorbing properties to a metal and non-metal heating element casing and a surface-treated metal sheet in accordance with the above-mentioned requirements, and to provide a metal having excellent heat absorbing properties. And non-metallic heating element housing and surface treated metal plate. A second object of the present invention is to develop a technique capable of imparting excellent heat absorbing properties to an outer panel in combination with the above-described object, and to provide a refrigerator and heat having excellent heat efficiency by providing an efficiency of 1313641 玖. A method for producing a refrigerator excellent in absorbability. A third object of the present invention is to provide a housing having improved heat dissipation in a portable type or in-vehicle device in which built-in heat-generating electronic components are provided, and to provide a portable type or in-vehicle apparatus having such a housing.

Fig. 2 is a view showing measurement of heat absorption. Figure 3 shows the embodiment of the measuring box. Embodiment 3 (Invention) In the present invention, the heating element may be any component that generates heat, such as a motor, an electronic component, a heater, a battery, etc., and is not particularly limited. In order to cover, surround, and store the heat generating body, etc., the user will be described below with reference to the heat-absorbing heat-generating body of the present invention, and the present invention will be described. The present invention is not limited to this, and is equally applicable to a non-metal heating element housing. The heat is a part of the electromagnetic wave that is scattered by the object, and the known system is reflected when the thermal radiation is incident on the object. It will be transmitted, and the remaining part will be absorbed. (For example, Nishikawa and Fujita, "Mechanical Engineering Fundamental Lectures and Electrothermal Engineering", P.289, Issued by: Institute of Science and Technology (1983). When the heat radiation is incident on the metal plate or the surface-treated metal plate, or the non-metal material, the heat radiation becomes a reflection or absorption because the heat radiation hardly transmits. 10 When the heat radiation generated by the heat generating body is incident on the inside of the heat generating body casing, the heat is smothered inside the heat generating body casing and the temperature inside the casing rises as soon as most of the incident heat radiation is reflected. Therefore, in order to reduce the temperature in the heat source casing, it is necessary to suppress the reflection of the heat radiation inside the casing. The present inventors have devoted themselves to the research, and as a result, the film 15 is now covered with a film layer having a high heat absorption property to suppress heat. Radiation reflection. It is well known that in the method for measuring the absorption rate of the heat radiation incident on the surface of a metal plate or a non-metal material, there is a reflection method by an infrared spectrophotometer, but when measured by the method, if a metal plate or 20 The thickness of the surface of the non-metallic material is too thick, and the incident heat radiation is scattered, so it is difficult to obtain a high-accuracy absorption rate. According to Kirchhoff's law on heat radiation, the absorption rate and the emissivity of the object are the same at a certain temperature (the "Mechanical Engineering Fundamental Lecture Electrothermal Engineering" by Nishikawa and Fujita, p.290, Issue: Science and Engineering Xueshe (sharp) 15 1313641 玖, invention instructions

The present inventors conducted a review in accordance with the law, and as a result, found that if a surface-treated metal sheet having at least a metal plate or a plated metal plate partially covered with a heat-absorbing film layer is formed, the outer cover is formed. 5 The heating element, wherein the heat absorbing film layer is in a region where the wave number is 600 to 3000 〇 11-1 measured at a temperature of 80 ° C or more and 200 t or less, and the total emissivity is 0. In the case of 70 or more, the temperature inside the casing is lowered as compared with the case where the casing made of the metal plate which does not cover the inner surface of the casing with the heat absorbing film covers the heating element. Similarly, it has been found that if the inner surface of the outer casing of the non-metallic material is 10 and the outer casing having the heat absorbing film layer covers the heating element, the heat absorbing film layer is at a temperature of 80 ° C or more and 200 ° C or less. The measured wave number is 600-3000 (in the region of 1111, the total emissivity is 〇. In the case of 7 〇 or more, the temperature inside the casing is lowered as compared with the case where the heat-absorbing body is not covered with the heat-absorbing film covering the inner surface of the casing. 15 Since the radiation absorption in the wavenumber region of the cycle number less than 600 CHT1 or more than 3000 cm1 is very small, the radiation rate of the radiation containing the wavenumber region is not appropriate. Further, when the heat-absorbing film layer having a total emissivity of less than 〇 7 is covered in a region having a wave number of 600 to 3000 cm-1, the effect of lowering the temperature in the outer casing is small, so that it is not suitable. Fig. 1 shows the structure of a metal or non-metal heat generating body casing excellent in heat absorption of the present invention. The metal or non-metal heating element peripheral of the present invention is composed of a metal plate or a non-metal material 1 and covers the inner surface with the heat-absorbing film layer 2. In addition, 3 in the figure is a heating element. If the heat-absorbing thin film layer 2 is covered with a flat metal plate or a non-metal material in advance, and it is processed to form a metal or non-metal heat generating body casing, the work efficiency can be improved in manufacturing. It is very suitable. Further, if the surface of the heat-generating body casing is not covered by a metal plate or a non-metal material covered with a heat-absorbing thin film layer, the effect of lowering the temperature in the heat-generating body casing cannot be obtained. The heat absorbing film layer can cover not only the inner surface of the heat generating body casing but also the outer side. When it is also covered on the outside, it is more suitable because the temperature of the heat generated by the metal or the non-metal is lowered by the heat radiation equivalent to the heat absorption. 1) A metal plate and a non-metal material for constituting a metal and non-metal heat generating body casing excellent in heat absorbing property of the present invention, in order to secure heat absorption, by at least a metal plate or a plated metal plate Or the non-metallic material is covered with a heat absorbing film layer on one side, and the heat absorbing film layer is composed of 100 parts by mass of the binder solid content, and b) 15 1 〇 15 〇 mass parts of heat The absorbent pigment is composed at 8 inches. . Above the war, the wave number measured at a certain temperature (4) ~ the area of the job ^ total radiation rate is 0. 70 or more. As the heat absorbing pigment, generally known ones such as carbon, carbon, and graphite can be used, and those which are commercially available can also be used. Among the heat-absorbing pigments, carbon black is more preferably dispersed in the film because the particle diameter is very large, so it is preferably a preferred pigment, and particularly preferably having a particle diameter of from 1 to 100 nm. The inventors have further discovered that the total emissivity of the film layer covering the metal plate or the non-metal material can be improved, and the film layer is added to improve the damage of the (4) absorption property. Or non-metallic materials 17 1313641 kan, invention instructions. Further, as the carbon referred to herein, generally known carbon such as carbon black, carbon or graphite can be used. In order to shield metal sheets or non-metallic materials by carbon, it is necessary to add a large amount of carbon having a smaller particle size. Even if a small amount of carbon having a small particle size is added, the shielding effect is small, and as for the carbon having a large particle size, even if a large amount is added, since a gap is formed between carbon and 5 carbon, the shielding effect is small. However, when a large amount of carbon having a small particle diameter is added, the viscosity of the coating liquid containing the solid content of the binder and the coating liquid of carbon is increased to lower the coating workability, and the fine particle carbon dispersed in the coating liquid is agglomerated after a period of time. The problem of making the coating liquid into a gel or the like. In order to solve such problems, the present inventors have made efforts to study, and as a result, it has been found that a small particle diameter of carbon and a particle diameter of O. The large particle size of carbon above 50w/m above lwm can solve the above problems. Because the carbon is dispersed in the film to disperse the large-size carbon in the gap, the particulate carbon is dispersed. Therefore, even if a large amount of fine carbon is not added, the shielding property of the carbon-shielding metal sheet and the non-metal material can be improved. And exerts a heat absorbing effect. 15 The preferred amount of the present invention obtained from the discovery, & an absorbent thin film layer (hereinafter referred to as an endothermic film) is added in an amount of carbon added to 100 parts by mass of the binder solid content, including The mass fraction is less than 0. The carbon of 1/zm and the particle size of 14 parts by mass of 碳 above the carbon of the heart m and the particle control is smaller than the particle size of 〇1 " m and the large particle size of the particle size of 20 m or more and 50/zm or less The total amount of carbon is 1 〇 to 15 Å by mass, and the film thickness of the endothermic film layer is at least. The lower limit of the particle size of the particulate carbon is not particularly limited. However, if it exceeds 01, a gap is easily formed between carbon and carbon, and the function as fine carbon is not exhibited, which is not preferable. If the amount of addition of the fine particles is less than 1 part by mass, the metal sheet or the non-18 1313641 玖, the metal material of the invention has poor shielding effect, and the heat absorbing property is also poor, so it is not suitable, and if it is more than 20 parts by mass, because it is coated The viscosity of the liquid becomes high and becomes gelatinous after a certain period of time, so it is not suitable. The particle size of the large particle size carbon is less than 0. 1/zm does not function as a large-size carbon, but exhibits the same characteristics as the 5-microparticle carbon, so it is not suitable. When the particle size of the large-diameter carbon is more than 50 m, when the coating liquid containing the large-diameter carbon is applied, the coating property is lowered and the appearance of the film after coating is poor, which is not preferable. The particle size of the large particle size carbon is preferably 0. 1"m or more 3〇em or less. Among them, it is better to be 1〇/m or less above 〇. If the amount of addition of the large-size carbon is less than 丨 by mass, the heat absorbing property is inferior, and if it is more than 140 parts by mass, the film becomes weak and the processability of the film is poor, which is not preferable. Further, if the total amount of the fine particles of carbon and the large particle size is less than 10 parts by mass, the heat absorption is poor, and if it is more than 150 parts by mass, the film becomes weak, and the processability of the film is poor, and the coating liquid It is not suitable because the viscosity is increased and the coating workability is poor. If the film thickness of the heat absorbing film is less than 1/zm, the heat absorbing property of the film is poor, which is not preferable. The metal plate and the non-metal material constituting the outer shell of the metal and non-metal heat generating body excellent in heat absorbing property of the present invention, in a preferred aspect thereof, are ensured to have at least heat absorption and conductivity. The metal plate or the plated metal plate, or the non-metal material is covered with a heat absorbing 20 film layer on one side, and the heat absorbing film layer is composed of a) 100 parts by mass of the binder solid content, and b 10 to 150 parts by mass of the heat absorbing pigment, in addition to c) 1-150 parts by mass of the conductive pigment, and the wave number 6 measured at a temperature of 8 〇 ° C or more and 200 Torr or less In the region of 〇〇~3〇〇〇(;]1^, the total emissivity is 0. 70 or more. 19 1313641 发明Invention and Description: A conductive metal can be used, such as a sheet metal Ni, a chain metal Ni, or a granular metal A1 scaly metal A1 'stainless steel powder. Commercially available, metal is generally easy. The heat of reflection has a tendency to hinder the heat absorption of the heat absorbing pigment. The metal Ni# has properties that are less likely to hinder the heat absorption of the heat absorbing pigment than other metal pigments, and since the chain metal Ni is chain-shaped, the area of heat reflected in the film is small, so that heat absorption is not easily hindered. More suitable. However, since the conductivity is poor if only the chain metal Ni is present, it is preferable to use the sheet metal Ni and the chain metal Ni. At this time, since the mass ratio of the sheet metal 10 genus Nl/chain metal Ni is ojm, the heat absorbing property and the conductivity are excellent. Different, so it is more suitable. The sheet metal Ni is likely to hinder heat absorption because of the large area of heat reflected in the film. Therefore, if the mass ratio of the sheet metal Ni/chain metal Ni is less than 0. 1 'The conductivity is poor. On the other hand, if it is more than 6, the heat absorption is poor. Further, if the conductive pigment is ferroniobium, the emissivity of the heat absorbing film layer can be improved, and the corrosion resistance can be improved when the metal sheet is surface-treated, which is more preferable. Since ferroniobium is excellent not only in electrical conductivity but also in heat absorbing property, it can also serve as both a conductive pigment and a heat absorbing pigment. Therefore, even if it is added alone, it can ensure both heat absorbing property and electrical conductivity. When the amount of the heat absorbing pigment added is less than 10 parts by mass relative to 100 parts by mass of the solid content of the binder, the area of the wave number of 600 to 3000 cm' is measured at a temperature of 80 ° C or more and 200 ° C or less. In the middle, the total emissivity of the metal plate is less than 0·70, so it is not suitable. 20 1313641 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明Since the impact resistance of the film layer is lowered, it is not preferable to reduce the workability in the processing of the metal plate. 5 The film thickness of the heat-absorbing film layer can be arbitrarily selected according to the needs, but if it is a metal plate, it should be, if it is a non-metal material, it should be l~l〇〇〇"m. If less than 1; zm, the wave number is measured at 8 (rc above 2 〇〇 t; below). In the area of (10), the total emissivity of the metal plate or non-metal material is difficult to become more than the above. Moreover, when the metal plate is 1 〇 greater than 5 〇 "m, since the workability of the film layer is lowered, it is not suitable. When it is a non-metal material, if it is more than 1000 #m, it is not economical because of heat absorption saturation. Further, if it is considered to be conductive, it is more preferably equal to or greater than lem and less than 10 #m. The binder used to constitute the heat-absorbing film layer of the present invention can be used as a tree resin and borrowed. A commonly known film binder for an inorganic film formed by a sol-gel method (s〇1_Gel) or an inorganic-organic composite film formed by a sol-gel method. The resin is used in the form of a coating, and the film formation method is used. It is easy to wait, so it is very suitable. The resin can be used by a general public, such as polyester resin, urethane acetate, acrylic acid resin, epoxy resin, melamine resin, vinyl chloride resin, etc. Any of the thermoplastic and thermosetting types. These resins may be used in combination with several types. These resins also impart film properties, such as processing, depending on the type, the molecular weight of the resin, and the glass transition temperature Tg of the resin. Sex, processing adhesion, film hardness, etc. 21 is called 3641 玖, invention description, so there is no (4) stipulations 'should be properly selected according to the needs. 'The type of resin that is hardened by the bridging agent is also due to the bridging agent. The type and amount of addition, the type of catalyst used in the bridging reaction, and the amount of catalyst added make the film properties, such as processability, processing adhesion, film hardness, etc., not particularly specific, and should be appropriately selected as needed. The solids of the tree month a can be melted and dissolved in an organic solvent to be pulverized into a secret body (4). Also, it can be a water-soluble resin and a water-dispersible emulsion type resin. It can also be an ultraviolet (uv) hardening type and an electron beam (EB) hardening type resin. These resins can be used in a commercially available type of 10. According to the findings of the present inventors, the solvent is a trimeric atmosphere. The amine-solid type polyester vinegar, the solvent-based isocyanate vine-solid type vinegar type, the water-dispersible acrylic acid emulsion, etc. are preferable, especially the following. However, these resins are only examples thereof. Not limited to 15 For the solvent-based melamine solid polyester system, the molecular weight of the polyester resin should have a number average molecular weight of 2000 to 30000'. The Tg of the polyester resin should be -10 to 70 ° C, and the amount of the melamine resin added is relative to 1 part by mass of the polyester resin is preferably 5 to 70 parts by mass. Since the molecular weight of the polyester resin is less than 2,000, the processability of the film is lowered by 20, and if it is more than 30,000 Å, the viscosity of the resin is too high when dissolved in a solvent. Therefore, it is not suitable. If the Tg of the polyester resin is less than one io°c, since the film does not form a film, it is not suitable, and if it is more than 70. (:, since the film is too hard, the workability is lowered, which is not suitable. The melamine resin When the amount of the polyester resin is less than 5 parts by mass, the film is not cured, and therefore the film is not cured. Therefore, it is not suitable for the invention. If it is more than 70 parts by mass, the film becomes too hard, and the workability is lowered. So not suitable. The polyester resin used can be used by a general marketer such as Toyobo Co. (TOYOBO Co.).  Ltd. ;Toyo Textiles Co., Ltd. "Byron (5 Vyl〇n 彳口 >)" 住 Sumika Bayer Urethane Co.  Ltd. "Staying the Eight Diagrams of the Workers' Days and the Nights of the Nights" ("Desmophen; 穸 only 7 workers >)" and so on. The melamine resin used can also be used by a general marketer such as Matsui Psytec Co.  Ltd. ; Mitsui F·〆亍v Xishe) "Semmel (10 Psymel; f·〆〆少)", "Mycoat (一))", Dainippon Ink Chemical Industry Company (Dainippon Ink) Chemicals Inc. ; Dainippon Chemical Industry Co., Ltd., "Bekamine" and "SuperBekamine". In the case of a solvent-based isocyanate-based polyester, the number average molecular weight of the molecular weight of the polyester resin is preferably from 2,000 to 30,000, and the Tg of the polyester resin is preferably from 10 to 7 〇 ° C. The addition amount of the isocyanate resin is When [NCO equivalent of isocyanate] / [〇H base equivalent of polyester resin] = 〇. 8~1. 2 o'clock is better. The value of [NCO group equivalent of isocyanate] / [〇 基 H base of the polyester resin] is less than 〇·8 or greater than 1. 2. When the film is produced, the film tends to become unhardened. When the molecular weight of the polyester resin is less than 2 Å, the processability of the film is lowered. If it is more than 30,000 Å, the resin is too high in solubility in the solvent, which is not preferable. The Tg of the polyester resin is less than -10. (3) Since the film does not form a film, it is not suitable. 'If it is larger than 70 ° C, the film is too hard, so 23 1313641 玖, the invention indicates that the workability is lowered, which is not suitable. The polyester resin used can be used in the general market. The sellers, for example, "Bailong" from Toyo Textile Co., Ltd., "Diesmoren" manufactured by Bayer Polyurethane Co., Ltd., etc. 5 Isocyanates used can also be used by general commercials, such as Suvarh Bayer. "Smidir (Sβ 2:1)", "Desmodur; 穸 乇, Takeda Chemicals.  Inc. ; Mitsui Takeda クミ力スレ社) "Takenate (Takenate; 夂 夂本一卜)" and so on. Further, the water-dispersible acrylic emulsion type resin may be used by a general public or a commercially available one. The water-dispersible acrylic emulsion type resin may be used by adding a resin having good adhesion such as a commonly known epoxy resin. Since the type and amount of epoxy resin will affect the film properties, it can be appropriately selected as needed. In the case of a 15 water-based resin such as a water-dispersible propionic acid resin, since the coating workability of the film is high and there is no problem of discharging the volatile organic solvent to the air, the reinforcing and volatility of the gas conduit are not (4) in the coating apparatus. The organic solvent combustion equipment, etc., is more suitable for the heat-absorbing film layer of 20 months, in addition to the heat-absorbing pigment and the conductive f-raw pigment, the coloring pigment and the anti-mineing pigment and the anti-mine may be added as needed. Agent. Coloring pigments can be used for oxidized zirconia (Ti〇2), oxidized (Ζη〇), oxidized (sound), carbon _ ((10) small barium sulfate (5) 〇 4), liquefied (铭203), Nanling clay, carbon Inorganic pigments such as black, iron oxide ((10) 3, 24 1313641 玖, invention description), and commonly known color pigments such as organic pigments. Further, as the rust preventive pigment, a generally known chromium-based rust preventive pigment such as strontium chromate or calcium chromate, and zinc phosphate, zinc phosphite, aluminum phosphate, aluminum oxalate, molybdate, phosphomolybdate, and vanadium can be used. A generally known non-chromium-based rust-preventive pigment and rust preventive agent such as an acid/phosphoric acid mixed pigment, cerium oxide, or a cerium oxide adsorbing a Ca-type cerium oxide. In particular, when the base material of the metal sheet of the present invention, such as a steel sheet or an electric ore steel sheet, is a corrosive metal, it is more preferable because the corrosion resistance of the metal sheet of the present invention can be improved by adding an anti-rust pigment and a rust preventive agent. 10 Non-chromium-based anti-rust pigments and rust inhibitors are more effective if you are concerned about environmental problems in recent years. These non-chromium-based rust-preventive pigments and rust-preventing agents can be used as reagents, and those which are commercially available. Commercially available anti-recording pigments, including Toho Coloring Inc. ;Dongbang Pigment Co., Ltd.) zinc phosphate anti-rust pigment "EXPERT-NP500 15", "EXPERT-NP530", zinc phosphite-based anti-rust pigment #"EXPERT-NP1500", "EXPERT-NP1530", " EXPERT-NP1600", "EXPERT-NP1700", Tika Corporation (Tayca Co. ; 彳力社) made aluminum tripolyphosphate "K-WHITE series", Sherwin Williams Co.

Further, the heat-absorbing film layer of the present invention may be added with a generally known bark dye, pigment dispersant, hydrazine or the like as needed. The type and amount of these additives are not particularly limited and may be appropriately selected as needed. In particular, the soiling is effective in improving the formability of the surface-treated metal sheet of the present invention, and preventing damage of the heat-absorbing film layer. In order to form the heat-absorbing film layer of the present invention on the surface of a metal plate or the surface of a non-metal material, the film component containing the binder may be applied in a coating form which is generally known. For example, the coating material includes a solvent-based coating material in which a resin is dissolved in a solvent, a water-based coating material in which an emulsion-formed resin is dispersed in water, a powder coating material in which a resin is pulverized and pulverized, and a pulverized and pulverized resin is dispersed. A slurry powder coating material such as water, an ultraviolet (uv) hardening type coating material, an electron beam (EB) hardening type coating material, a film laminate in which a resin is adhered in a film form, a form in which a resin is melted, and then coated. In any of the above, the coating method is not particularly limited, and a coating method such as 'roller coating, roller curtain coating, curtain coating, air spraying, airless spraying, brushing, or the like can be employed. Mold coating, etc. Further, dip coating or ink jet coating is also possible. Further, before the metal plate covers the heat absorbing film layer, in order to improve the film adhesion of the metal plate, the metal plate should be pretreated. If it is carried out 26 1313641 玖, the invention explains the pretreatment, it is more suitable to improve the adhesion of the heat absorbing film and the financial corrosion of the metal plate. Since the coating film can be adhered to each other without performing the coating pretreatment, the coating pretreatment can be omitted, which is more preferable. The coating front portion can be generally used, for example, a chromate treatment, an electrolytic chromate treatment, a zinc phosphate treatment, a zirconia treatment, or a titanium oxide treatment. In addition, in recent years, non-chromate pretreatments based on organic compounds such as resins have been developed. If a resin-based non-chromate pretreatment is used, the environmental load can be reduced. More suitable. (10) The non-chromate pretreatment based on an organic compound such as a resin may be exemplified by Japanese Laid-Open Patent Publication No. Hei 09-828291, Japanese Patent Publication No. Hei-251509, No. 10-337530, and JP-A-2000- The techniques disclosed in 15 of No. 17466, JP-A-2000-248385, JP-A-2000-273659, JP-A-2000-282252, JP-A-2000-265282, JP-A-2000-167482, etc. can be used. Techniques, in addition to the foregoing, general well-known techniques can also be used. Non-chromate treatments already on sale can also be used. Since the adhesion between the heat-absorbing film layer and the corrosion resistance of the metal plate are greatly different depending on the type of the pretreatment treatment and the amount of adhesion, it is necessary to appropriately select it according to the need. Since the metal plate of the present invention is processed to form a metal heat-generating outer casing, a metal material which is generally known can be used as long as it is a metal material which can be processed. The metal material may also be an alloy material. For example, steel, aluminum, titanium, copper, magnesium alloy or the like can be exemplified. In particular, if a heat conduction such as aluminum or copper is used, the metal having a high rate of description is uniformly dispersed in the metal, and the metal is locally heated, so that it is very suitable. Moreover, the surface of such materials may also be electroplated. The type of plating may be exemplified by galvanizing, aluminizing, ore plating, nickel plating, or the like. Also 5 can be plated alloy. In the case of a steel sheet, a cold-rolled steel sheet, a hot-rolled steel sheet, a hot-dip galvanized steel sheet, an electrogalvanized steel sheet, a hot-dip galvannealed steel sheet, an aluminum-plated steel sheet, an aluminum-zinc alloy plated steel sheet, or a stainless steel sheet can be applied. Steel plate and plated steel plate. However, if the hot-dip galvannealed steel sheet, the iron- and zinc-plated alloy steel sheet 10 has high heat absorbing property by itself, it is preferable to cover the heat-absorbing film thereon to further improve heat absorption. Further, when a steel sheet coated with a metal having a high thermal conductivity such as aluminum or copper is coated with a heat absorbing film, the absorbed heat is uniformly dispersed through the plating layer on the metal surface, and it is more preferable since the metal is locally heated. These steel sheets coated with 15 metals having a high thermal conductivity such as aluminum and copper are not only improved in thermal conductivity, but also have the strength and formability possessed by the steel sheet, and are compared with metals having high thermal conductivity such as aluminum and copper which are used alone. It is cheaper, so it is more appropriate to reduce the manufacturing cost of the invention. These metal sheets may be subjected to general treatment such as hot water washing, degreasing, pickling, and the like before the coating pretreatment. A general known processing method can be used for the processing method for forming a metal into a heat generating body casing. For example, a processing method such as forging processing, casting processing, punching processing, bending processing, extension processing, expansion processing, and roll forming can be exemplified. Further, if the heat-absorbing film layer is coated on the metal plate in advance, the pre-coating method of the re-forming process is more preferable because of the high production efficiency. 28 1313641 玖, Invention Description 5 10 15 20 The non-metallic materials used in (4) are all inorganic materials and organic materials other than metal materials, in addition to plastics, resins, ceramics, pottery, cement, etc., or natural materials. Further, among the resins, a generally known resin such as an acrylic resin, a vinyl chloride resin, a resin, a naphthalene resin or a polycarbonate resin can be used. In addition, ceramics can be used as well as known ceramics such as oxidized inscriptions, nitrided (four), titanic acid, and titanic acid. In addition, if it is a non-metallic material, it may be subjected to a generally known chemical conversion treatment such as a surface of a non-metallic material to be covered with a heat-absorbing thin medium as needed, such as making the roughness coarser, and the like. improve. The heat-generating body casing and the material thereof which are excellent in heat absorption property of the present invention may, for example, be VTR, audio equipment, qing, television, liquid crystal television, plasma display tuner, etc., and other peripheral devices, personal computers, Personal computer peripherals such as notebook PCs, CD-ROM drives, hard disk drives, mobile phones such as mobile phones and electronic notebooks, refrigerators, air conditioners, air conditioners, washing machines, lighting fixtures, etc. Ticket machines such as housings, car battery cases, in-vehicle electronic parts machines, car navigation systems, car audio equipment, vending machines, currency machines, prepaid cards and tickets. The outer casing and internal parts of these machines are included. The use of the present invention in the P electronic component set and the internal and external control machine casing can exert an effect. In the following, a refrigerator, a portable device, and an in-vehicle device which have been confirmed by the inventors of the present invention have been described. 29 1313641 发明Inventive description The refrigerator uses a large number of parts such as motors and electronic parts that are used as heat sources. In particular, in recent years, the electronicization of refrigerators has continued to develop, and the heat generated by these heat sources is accumulated in the interior of the refrigerator, so that the internal temperature is easily increased. Once the temperature inside the refrigerator rises, in order to lower the temperature in the refrigerating compartment, more power is required, and thus the life of the motor and the electronic component is also shortened. However, in recent years, from the viewpoint of ecology, there has been an increasing demand for lowering power consumption of electrical products such as refrigerators. The present inventors have made an effort to review and found that if the heat-absorbing property of the surface of the metal material is imparted on the inner side of the outer panel of the refrigerator, the motor is not compared with the case where the heat-absorbing material is not the same as the heat-absorbing material. The temperature near the heat source will decrease. In the past, the heat-generating body casing and the heat-absorbing film have been described. Since the outer plate constituting the refrigerator is assumed to be a heat-generating body casing, it is also directly applicable to heat absorption of the outer panel of the refrigerator and the inner surface thereof of the present invention. The specific description of the film 15 is omitted here. The refrigerator of the present invention has the same construction and interior as the known one except that the inner surface of the outer panel is covered with a specific heat absorbing film. When the outer surface of the outer panel of the refrigerator of the present invention is covered with a colored coating film and a transparent coating film, it is more suitable because it can impart a design appearance. The colored coating layer 20 and the transparent coating layer may be multi-layer coated, and the lowermost layer is used as an anti-rust coating layer containing an anti-mineral pigment, whereby the upper layer is used as a coloring layer containing a coloring pigment, and if necessary, Moreover, it is more suitable for covering a transparent film, etc., since it can improve corrosion resistance and enhance design when it is a metal plate, so it is more suitable for 30 1313641 发明, invention description, and steps of assembling a refrigerator, because of a conveyor belt or the like The friction of the conveyance machine causes static electricity to be generated on the surface film of the metal plate for the outer panel of the refrigerator, and the dust in the assembly line adheres to the surface of the metal plate. In order to solve this problem, it is necessary to impart conductivity to the coating film to discharge static electricity accumulated on the surface of the film. The heat absorbing film layer covering the inner side of the outer panel of the refrigerator of the present invention contains, in addition to the carbon, a conductive metal powder of i parts by mass with respect to 1 part by mass of the solid content of the binder. It is wire-oriented and can solve the problem of dust adhesion caused by static electricity in the assembly step of the refrigerator, and is more suitable. The structure in which the heat absorbing film layer is imparted with conductivity is also described previously. When the refrigerator of the present invention is produced, the heat-absorbing film layer of the present invention is applied to a single surface of a flat metal sheet in advance to prepare a pre-coated metal sheet having high heat absorbability, and after being cut and processed, the group is When it is installed in a refrigerator and the heat absorbing film layer is located inside the outer panel, it is more suitable because the work efficiency is high. When the refrigerator of the present invention is produced, a pre-coated metal sheet covered with a heat-absorbing film in advance, and then a cutting method of "processing and assembly" can be used, and a generally known processing method can be used. For example, processing methods such as equal punching processing, threading processing, drawing processing, expansion processing, and roll forming can be exemplified. According to the present invention, the high heat absorbing paint of the present invention is applied to the inner surface side of the electronic machine casing in which the heat generating electronic component and the battery are built, and the temperature rise inside the electronic device can be remarkably suppressed. 31 1313641 In the present invention, the portable device (mobile & machine) and the in-vehicle device are not particularly limited, and include a mobile phone, a personal computer, a PDA, a car battery, a car navigation system device, and ^ Car audio machine, car control machine, etc. The heat-generating electronic component is not particularly limited, and refers to an electronic component such as a CPU component, an MPU component, a DSP component, an electronic integrated circuit, a resistor, and the like. Also, batteries are generally known to be applicable. The material of the casing of the portable machine or the in-vehicle device of the present invention is also not particularly limited, and examples thereof include a Mg alloy casing, an alloy casing 10, a steel plate casing, other metal casings, and a plastic casing. However, the present invention is particularly useful when the Mg alloy case, the A1 alloy case, and the steel plate case are particularly used. The heat absorbing film layer of the casing of the portable machine or the in-vehicle device of the present invention is in the form of a towel. The towel is a component of the binder solid 15 with respect to (10) f parts, and contains 1 to 20 parts by mass of the particle size less than O. The carbon of l/zm and the particle size of 1 140 mass 1 injury 〗·〗 v m or more and less than m carbon, and the particle size is smaller than the carbon and particle size 〇. The total amount of carbon of 1//m or more and 5 〇#m or less is 10 to 150 parts by mass. In the second aspect, the heat absorbing film layer is composed of 1 part by mass of the binder solid content, 10 to 150 parts by mass of the heat absorbing pigment, and 1 to 150 parts by mass of the conductive pigment. And the heat absorbing pigment is carbon black having an average particle diameter of 1 to 10 nm, and the conductive pigment is composed of a sheet metal Ni and a chain metal Ni having an average particle diameter of 0_5 to 50/zm, and the sheet The mass ratio of the metal Ni/chain metal Ni is 〇. ι~6. 32 1313641 发明Inventive Description The heat absorbing thin layer is composed of 100 parts by mass of the first solid content of the binder, 1 〇 to 15 (1) to 150 parts by mass of ferroniobium. In the fourth aspect, the heat-absorbing pigment and the heat-absorbing film layer of the heat-absorbing pigment are contained in an amount of 50 parts by mass based on the solid content of the binder. The contents of the heat absorbing film layers of these various aspects are substantially the same as those previously described for the heat generating body casing. Therefore, the detailed description thereof is omitted here. Further, it is also possible to use the heat generating body casing or the like as a casing of a portable type vehicle or an in-vehicle apparatus. In order to form the highly heat-absorbing film layer of the present invention on the surface of the casing, the film component containing the binder may be applied in the form of a coating which is generally known. For example, 'the coating form includes a solvent-based coating material in which a resin is dissolved in a solvent, an aqueous coating material in which an emulsion-forming fat is dispersed in a water towel #, a powder coating which is pulverized by a user's fat, and a powder which is pulverized and pulverized. A bulk powder coating such as water, an ultraviolet (UV) curable coating material, an electron beam (εβ) hardening type coating material, a film laminate in which a resin is adhered in a film form, a form in which a resin is melted, and then coated. The film thickness of the high heat absorbing film is preferably biOOOvm. If the film is smaller than l#m, it is not suitable because the heat absorption of the film is poor. If the film is larger than 20 1000# m, it is not suitable because it is not absorbed by heat absorption. Among them, 1〇~500/zm is more preferable. In order to ensure conductivity, it is more preferable to be greater than or equal to 1/zm and less than loem. Generally, the high heat absorbing film layer of the present invention is applied to the surface after forming the casing. However, in the case of a sheet material, it is also possible to apply 33 1313641 玖 and the invention sheet before the forming process. In the present invention, the temperature inside the electronic device and the battery can be lowered by making the surface covered with the heat-absorbing film layer the inside of the heat-generating electronic component and the casing of the battery. 5 The structure of the casing excellent in heat absorption of the present invention can be the same as that of the first embodiment. The casing of the present invention is composed of, for example, a Mg alloy sheet, and is characterized in that the inner surface is covered with the high heat absorbing film layer 2. In addition, the 3 in the figure is a heating electronic component or battery. Further, if the surface covered with the high heat absorbing film layer is not the inner surface 10 of the casing, the effect of lowering the temperature in the casing of the electronic device cannot be obtained. However, the high heat absorbing film layer may be outside the inner surface of the casing and also cover the outer side. When it is also covered on the outside, it is more preferable because the heat absorbed by the metal sheet which is the outer shell of the heat generating body can be easily released due to the influence of the heat radiation equivalent to the heat absorption. 15 Also, the colored coating film may be covered on the outer side of the casing to impart a design appearance. The colored coating film layer may be coated in multiple layers. When the casing is made of metal, the rust-preventing coating layer as a rust-preventing pigment may be used as the lowermost layer, and the upper layer is used as a coloring layer containing a coloring pigment. In these cases, the colored organic film layer (including the rust-preventive coating layer if it is a multilayer coating film) itself has a certain degree of thermal radioactivity, so if the total coverage is I0#m or more, the shell can be made. The temperature of the body is lowered, so it is more suitable. EXAMPLES Hereinafter, a method of producing a heat absorbing thin enamel paint for use in an experiment will be described in detail. 34 1313641 发明, Invention Description A commercially available organic solvent soluble/amorphous polyester resin (hereinafter referred to as polyester resin) manufactured by Toyo Kogyo Co., Ltd.

The slashing method of the checkerboard pattern, the extrusion method of the Ehrlich's method, and the method of the tape peeling test are carried out in accordance with the method described in JIS-K5400.8.2 and the method described in JIS_K5400.8.5. In addition, in this test, the tape peeling test (hereinafter referred to as the second tape peeling test) was carried out twice in the same place. The evaluation of the 2 〇 tape peeling test was carried out according to the chart of the evaluation example described in JIS-K5400.8.5, and when the score was 10 points, it was rated as ◦' greater than or equal to 8 points and less than 10 minutes, and was rated as △, and when less than 8 minutes, it was rated as X. . 4) Bending test of the coating The 180 ° C bending process was applied to the prepared surface coated plate. Then, 50 1313641 发明, invention description The state of the coating film damage of the processed portion was observed with a magnifying glass, and evaluation was performed by the following criteria. The bending and Guarding System is implemented in a 2 (rc environment, with three 0_6mm spacers sandwiched between the spacers (generally called 3τ bending). When the coating film is completely damaged: 〇5 When the coating film is partially damaged: △ When the coating film is seriously damaged on the entire surface of the processing section: X 5) Stamping forming test The surface coating plate produced is subjected to a cylinder lead-in test using a hydraulic type Ehrlich type stamping tester. The cylinder lead test is performed at the punch diameter: 1〇5〇 face, punch shoulder R: 5, die shoulder R: 5 赖, extension ratio: 2 3 , BHF: lt condition, and proceed Lift until the metal plate is pulled out by the mold. Further progress, the state of the coating film damage of the processed portion was observed with a magnifying glass, and evaluation was made by the following criteria. 15 When the coating film is completely damaged: When the coating film is partially damaged: △ When the coating film is seriously damaged on the entire surface of the processing part: χ 6) Tolerance, for the surface coated plate produced, use IIS-K54GG. The water spray test is carried out in the method of 9.1. The water test system is sprayed on the surface of the heat absorbing film layer. Let the test time be 12〇h. ▲ Use a cutting knife to draw a cross section on the surface of the test piece. The coating film of the cross-section is the maximum foaming width on one side of the cross-section. The maximum foaming width on one side of the cross-section is less than or equal to 2 mm and less than 5 mm, and is evaluated as △, when brewed above 51 1313641 玖, the invention description is rated as X. In addition, the above-mentioned alkali water spray test was also carried out on the flat plate on which the burrs (hairs) at the time of cutting were produced on the side of the 6-valency side of the coated steel sheet (which became the upper burrs), and the coating film from the end surface was observed.

The method of flattening the end face 5 is rated as 〇 when the blister width of the end face is less than 2 mm, Δ when it is greater than or equal to 2 mm and less than 5 mm, and X ≥ when it is 5 mm or more. 7) Surface prepared by conductivity test The conductivity 10 of the heat-absorbing film layer of the coated sheet was measured by a four-terminal method using a resistivity meter rL〇resta Ep/MCp_T36〇 manufactured by Mitsui Chemicals, Inc. (Mitsui Chemicals, Inc.). The resistivity of the surface of the board was evaluated by the following criteria. When the resistivity is less than Ο.ΐχ 10·2Ω: 〇15 Resistivity is greater than or equal to 〇·ΐχ 1〇-2 and less than Ι.Οχ Hrh: △ Resistivity is 1·〇χ 1〇-1Ω or more: X or less The evaluation results of the surface coated panels produced were revealed. The evaluation results of the effects of the added pigment and the added amount on the heat-absorbing film layer covering the surface-coated sheet are shown in Table 5. 2〇, the surface-coated sheet of the present invention (Examples 1-1 to 1-25 of the present invention) has a wave number of 600 to 3000 measured at a temperature of 80 C (in the region of 111-1, the total emissivity is 0.70 or more) Comparative Examples 126 and 127, which have a lower emissivity than 〇7〇, are suitable as the outer shell of the heating element. The heat-absorbing thin film layer of the surface-coated sheet of the present invention is composed of 1 enamel 52 1313641 发明, description of the invention It is more suitable for the case where it is composed of a solid component of a mouth-and-mouth agent, a heat-absorbing pigment of 10 to 15 parts by mass, and a conductive pigment of 1150 mass of a wound, which is excellent in workability and electrical conductivity. If the amount of the material to be added is less than 1 part by mass (comparative example is 5)', the emissivity is less than 〇7, and the heat absorbing property is poor, so it is not suitable. The amount of the heat absorbing pigment added is more than 15 parts by mass. (Inventive Example 15), although the emissivity is high, the workability such as the bendability and the press formability is lowered, so that it is preferably 150 parts by mass or less. The amount of the conductive pigment added is less than j parts by mass. Example _8 ) 10 , the conductivity cannot be ensured due to the change When the amount of the conductive pigment added is more than 15 parts by mass (Comparative Example 127), since the conductive pigment hinders heat absorption, the emissivity becomes less than 〇7 and the heat absorbability is poor. Further, the processability of the film layer is also greatly lowered, which is not preferable. 15 The heat absorbing pigment contained in the heat absorbing film layer of the surface coated plate of the present invention is carbon black having an average particle diameter of PiOOnm, and the aforementioned conductive pigment It is composed of a sheet metal Ni and a chain metal Ni having an average particle diameter of 55~50"m and a mass ratio of sheet metal Ni/chain metal Ni (u~6, due to heat absorption and It is more suitable because it is more excellent in conductivity. 20 If the heat-absorbing pigment is larger in particle diameters such as carbon powder and graphite powder (Inventive 1-6 and 1-7), due to lower emissivity and large heat absorption The pigment may hinder the conductive effect of the conductive pigment and lower the conductivity, so that the heat-absorbing pigment is preferably a carbon black having an average particle diameter of 1 to 100 nm. The heat-absorbing film layer included in the surface coated sheet of the present invention. Conductive 53 1313641 rose, invention description of the face If the aluminum powder and stainless steel powder, conductive paint such it is easy to hinder

116) The rate of emissivity is reduced.

'The conductivity is lowered, and if the mass ratio of the sheet metal Ni to the chain metal Ni is more than 6 (inventive example M4), the heat absorption is hindered and the emissivity is low, so the sheet metal Ni/chain metal Ni The mass ratio should be 〇1~6. When the conductive pigment is ferroniobium (Inventive Example 1-17), the emissivity is not lowered, and the corrosion resistance of the surface-coated sheet of the present invention is also improved, which is more preferable. The addition of the heat absorbing pigment and the addition of only the strontium iron (Example 19 of the present invention) is very suitable because it has a high emissivity and is excellent in electrical conductivity and resistance to the surname. Further, when conductive carbon black is used as the heat absorbing pigment, it is more preferable because conductivity can be improved. In the heat-absorbing film layer of the surface-coated sheet of the present invention, in addition to the heat-absorbing pigment and the conductive pigment, those having an anti-mineral pigment (Inventive Examples 1-22 to 1-25) are excellent in corrosion resistance. Therefore, it is more suitable. The evaluation results of the surface-coated sheets having different heat-absorbing film layers having different film thicknesses are shown in Table 6. Since the film thickness is less than 1/zm (inventive example 28), the total radiation rate is low and if more than 50 cm, the workability of the film layer is lowered, so that the film thickness is preferably from 1 to 50/zm. Table 7 shows the case where the chromate treatment is used as the heat absorbing film layer 54 1313641 玖, the description of the invention (inventive example 1_35), and the case where the pretreatment is not performed (inventive examples 1-36) Evaluation results. Although the type of pretreatment was changed, the emissivity and heat absorption and other film properties did not change. However, since the chromate treatment method produces an environmental problem in which the chromate treatment thin film contains hexavalent chromium, the treatment without chromium (non-chromate treatment) is suitable. Further, in the case where the pretreatment is not carried out, since the coating film adhesion and the silver resistance are lowered, it is preferable to carry out the pretreatment. Table 8 shows the results of heat absorption evaluation in the case where only one side of the heat absorbing film layer was covered and the other side was not coated. Only those who are covered with a heat absorbing film layer on one side have a lower heat absorption than those covering both sides. When only one side was covered, the heat absorbing film layer was covered on the outer side of the outer casing for covering the heat generating body which became the heat source (Comparative Example 1_38), and heat absorption was almost ineffective, which was not preferable. 15 (Example II) Hereinafter, a method of producing a heat-absorbing surface-coated sheet for use in an experiment will be described in detail. An electrogalvanized steel sheet having a thickness of mm6 mm plated on both sides of an adhesion amount of 20 g/m 2 per one surface was immersed in a "product of FC_364S" manufactured by Pak Lai Jang 20 Co., Ltd. of the commercially available basic degreaser to 20% by mass. The concentration was carried out in an aqueous solution of 60X: for 10 seconds to thereby degrease, and after washing with water, it was dried. Then, the chemical conversion treatment liquid was applied onto the degreased electrogalvanized steel sheet by a roll coater, and reached a sheet temperature of 60. (The condition is to make it hot and dry. 55 1313641 玖, invention description In this test, the chemical conversion treatment is "ZM1300AN" (hereinafter referred to as chromic acid) manufactured by 帕本本克克莱珍古公司 using a commercially available acid salt.

Hereinafter, the evaluation criteria of the temperature A will be described. Further, in the present experiment, the a surface of the surface coating plate to be formed was set to the inner side (heat source side) of the measuring box.

However, in this test, the adhesion of the a side was evaluated. 59 1313641 发明, invention description 4) The bending test of the coating film is the same as in the first embodiment. However, in this test, the side of the a surface was formed on the outer side of the processed portion, and the state of the coating film of the processed portion on the a surface was observed and evaluated. 5)) Stamping forming test The same as in Example I. However, in this test, the side of the a surface was formed on the outer side of the processed portion, and the state of the coating film of the processed portion on the a surface was observed and evaluated. 6) Property name 〇 The alkali-coated spray test is performed on the surface-coated board produced by JIS-K5400.9.1. The alkaline water was sprayed on the side of the test piece. Let the test time be 72h. Then, the state of occurrence of white ore in the plane portion and the end surface of the a-side is observed, and when the white scale is not produced in the plane portion and the end portion, it is evaluated as ◎, when the end surface portion has some white rust and the plane portion has almost no white town, 15 is 〇, when the end face produces a white record and the flat portion also locally produces white ore, it is rated as △, and when the end face and the flat face are completely white rust, it is evaluated as X. 7) Conductivity test The same as in Example 1.

: X 9) Appearance of heat absorbing film The appearance of the film covering the a side of the metal plate was visually observed and evaluated as follows. 5 Smooth appearance: 〇 Since the added pigment is only a little thicker than the film thickness, it can be observed that the surface of the film has a concave and convex appearance: △

Since the addition of the pigment is much more than that of the film, it is observed that the surface of the film has a sharp uneven appearance: X 10 or less, and details of the evaluation results are detailed. The surface-coated sheet of the present invention is obtained by covering a heat-absorbing film layer having a dry film thickness of above to obtain a surface-treated metal sheet having high heat absorbability, and the heat-absorbing film layer is combined with 1 part by mass. The solid content of the agent comprises 1 to 20 parts by mass of carbon having a particle diameter of less than 〇"m" and a mass of 15 to 14 parts by mass of o.i"m or more and 50/zm or less, and the particle diameter is less than O. The carbon of the .lAin and the carbon having a particle diameter of #1#m or more and 5〇//m or less are 10 to 150 parts by mass. When the heat-generating body casing is formed by the surface-coated board of the present invention, it is necessary to use the heat-absorbing film as the inside of the heat-generating body casing. Since the heat absorbing film of the present invention covers only the outer side of the heat generating body casing (Comparative Example 11-32), the temperature inside the casing (endothermic temperature A) hardly decreases, so it is not suitable for the surface of the present invention. In the heat-absorbing film layer of the coated sheet, in the region where the wave number is 600 to 3000 cm-1 measured at a temperature of 80 ° C, the total emissivity is less than 61 1313641 玖, and the description of the invention is 〇·7〇 (inventive example η· 26), * The temperature inside the casing (endothermic: temperature a) hardly decreases, so it is preferable that the total emissivity is 〇7〇 or more. When a conductive pigment is added to the heat-absorbing film layer of the present invention (the example of the present invention), since conductivity is imparted, it is more preferable to use the heat-generating body casing for the purpose of grounding. When the rust preventive pigment is added to the heat absorbing film layer of the present invention (Example Π13, ΙΜ4 of the present invention), since the corrosion resistance is improved, it is more suitable for applications requiring corrosion resistance. Further, when ferroniobium having both corrosion resistance and electrical conductivity is added to the heat-absorbing film layer of the present invention (Example Π-12 of the present invention), since conductivity is imparted, corrosion resistance is also improved, so that it is more suitable. Further, the heat-absorbing film is covered only on the inner side of the heat-generating body casing, and the outside is not covered with anything. Although the temperature inside the casing (endothermic temperature Α) is low and the heat absorbing property is excellent, the temperature of the metal plate itself (endothermic temperature Β) )high. Therefore, it is more preferable to cover the heat-absorbing film on the inner side of the heat-generating body casing 15 and to cover the heat-absorbing film of the present invention of 10 or more on the outside or a generally known color-coated film. (Example III) Hereinafter, a method of producing a heat-absorbing surface-coated sheet for use in an experiment will be described in detail. A hot dip-plated zinc-plated steel sheet (〇Α) having a thickness of 6.6 mm plated on both sides of a plating amount of 60 g/m 2 per one side, and impregnated with a commercially available basic degreasing agent from the company The "FC-364S" was diluted to a concentration of 20% by mass in an aqueous solution at a temperature of 60 ° C for 1 Torr, thereby degreasing, 62 1313641 玖, and the invention was washed with water and dried. In addition, the aluminum plated steel plate (aluminum steel plate) having a thickness of 66 mm and the aluminum plate (AL) having a thickness of 66 mm were plated on both sides of the electrode bonding amount of 6 〇g/m2 per one side, and impregnated with commercially available aluminum. It was diluted with a basic degreaser "FC_315" manufactured by Pak Lai Jung Co., Ltd., into a 4 wt% aqueous solution of a temperature of 5 ° C C for 10 seconds to degrease, and washed with water and dried. Then, the chemical conversion treatment liquid was applied to the degreased plated steel sheet and the aluminum plate by a roll coater, and dried by hot air at a condition that the sheet temperature reached 6 (rc). 10 15 20 In this experiment, the chemical conversion treatment was performed using the city. The non-chromate treated 曰本本克克赖珍古公司 t "CT-E3GG". The chemical conversion treatment is carried out on both sides of the metal plate by a roll coater and dried under conditions of a plate temperature thief. The amount of the chromate treatment was such that Cr was 5 〇mg/m 2 and the amount of adhesion by the non-chromate treatment was 2 〇〇 mg/m 2 in terms of the total amount of the film. Further, the embodiment was applied by a roll coater. The coating material 1-2 contained in the table of 〗 is applied to one side of the plated steel sheet subjected to the chemical conversion treatment (hereinafter referred to as a side), and dried and hardened by an induction heating furnace of hot air. The arrival plate temperature (PMT) is 23 Gt. The test piece is obtained by applying the chemical conversion treatment and the heat absorption film coating to one side or both sides as needed, and the other side (hereinafter referred to as b side) It is a color coater. In addition, the color coat coating is applied to Japan.

The test 15 is the same as in the embodiment II. Details of the evaluation results will be described in detail below. The surface coated plate of the present invention, if the original plate is a plated iron-zinc alloy steel plate such as a hot-dip alloyed zinc-plated panel (Example 111_ of the present invention)丨), the emissivity will become higher and more suitable. Further, if the original plate is made of a material having high thermal conductivity such as aluminum (Inventive Example 3), and if such a material is plated on a steel material or the like (Inventive Example ΙΙΙ-2), since the heat is in the metal It is more suitable for the surface of the plate or the metal plate to diverge, and the heat of the surface of the metal plate is uniform. (Example IV) The following is a detailed description of the preparation of the heat-absorbing coated sheet used in the experiment. The heat-absorbing film coatings shown in Table 3 were applied to a plate-like cerium oxide _ (referred to as τ plate) by a bar coater, and dried at normal temperature for about 24 hours. In addition, it is applied as needed to form a two-side coater and a one-side coater. The details of the finished surface coated panels are shown in Tables 12-14. Tables 12 and 13 are not coated with the same type of heat absorbing film layer on both sides under the same conditions, and the surface coated sheets shown in Table 14 are all hot.

Hereinafter, the evaluation test of the produced coated outer casing will be described in detail. 1) The emissivity measurement of the surface coated sheet material was the same as in Example 1. 5 2) The heat absorption measurement test of the surface coated plate material was the same as in Example I, but in the present experiment, only the temperature of the thermocouple 8 in Fig. 2 was measured. Further, the same measurement was also performed on the untreated sheets which were not coated, and the measured values were compared and evaluated by the following criteria. 10 [{(measured value of untreated board)_(measured value of surface treated board evaluated)} 24°C]: 〇69 1313641 玖, invention description [4°C> {(measurement of untreated board) Value) - (measured value of the surface treatment plate evaluated)} 22 ° C]: △ [2 ° C > { (measured value of untreated plate) 1 (measured value of the surface treated plate evaluated) }〕: χ 5 3) Conductivity test measures the conductivity of the heat-absorbing film layer of the surface-coated sheet produced. The measuring method is to mount a flat electrode sample measuring electrode (SME-8310) made by East Asia Electric Wave Industrial Co., Ltd. (DKK_T〇A c〇; Dongpu Radio Industry Co., Ltd.) to a resistance measuring device (SM-8220) manufactured by East Asia Electric Wave Co., Ltd. 10 Surface resistivity of the film surface, and evaluated by the following criteria: When the surface resistivity is less than or equal to 〇X: When the surface resistivity is greater than 1.0χ 109Ω and less than or equal to i 0χ 1〇11〇: Δ Surface resistivity When it is greater than 1·〇χ 1〇11〇: X 15 4) Impact resistance test of the coating film The DuPont impact resistance test of JIS K 5400 8·3·2 was carried out. In addition, the size of the trapping die when the test was performed was 1/2 inch (12.7 mm), the weight of the weight code was 500 g, and the height of the weight code was 2 〇cm. Then, the surface of the sample after the test was visually observed and evaluated by the following criteria. 10 When it is not possible to confirm the cracking and peeling of the coating film: When the film is cracked and peeled off: △ The evaluation results of the influence of the added pigment and the amount of the heat-absorbing film layer covering the surface-coated sheet reveal In Table 12. Further, in Table 12, the test results of applying the same condition heat-absorbing film to the samples of the non-metal 70 1313641 玖 and the two sides of the invention sheet were used. It can be seen that the surface-coated sheet of the present invention (Examples IV-1 to 20 of the present invention) has a total emissivity of G in a region where the wave number is 6 〇〇 to 3 〇〇〇 cm ^ measured at any temperature of 80 C or higher. In the case of 7G or more, the comparative examples 5 and 22 having a lower emissivity than G.7G have high heat absorption and are suitable as a casing for the heating element. The heat-absorbing film layer of the surface-coated sheet of the present invention is formed by a 100-component wound L-component solid component, 10 to 150 parts by mass of a heat-absorbing pigment, and 1 to 150 parts by mass of a conductive pigment. Those who are excellent in sex and conductivity are more suitable. If the amount of heat and replenishing material added is less than 10 parts by mass (Comparative Example IV-21), since the emissivity is less than 07, heat absorption is poor, which is not preferable. When the amount of the heat-absorptive pigment added is more than 150 parts by mass (Inventive Example IV_5), the emissivity is high, but the impact resistance is lowered. Therefore, it is preferably 1 part by mass or less. When the amount of the conductive pigment added is less than 1 part by mass (Example 8 of the present invention), since conductivity cannot be ensured, it is preferably y or more by mass. When the amount of the conductive pigment is more than 150 parts by mass (Comparative Example IV-22), since the conductive pigment impairs heat absorption, the emissivity becomes less than 0.7 and the heat absorbability is poor, and the impact resistance of the film layer is also largely lowered, so that it is not suitable. . The heat absorbing pigment contained in the heat absorbing film layer of the surface coated sheet of the present invention is carbon black having an average particle diameter of from 1 to 100 nm, and the conductive pigment is composed of an average particle diameter of 5.5 to 5 〇em. The mass ratio of the sheet metal Ni and the chain metal Ni to the sheet metal Ni/chain metal Ni is preferably 0.6%, which is more preferable because it is more excellent in heat absorbing property and conductivity. 71 1313641 The invention discloses that if the heat absorbing pigment is larger in particle size such as carbon powder and graphite powder (this V 6 and IV-7 ), the emissivity is low and the conductive effect of the conductive pigment is hindered. The conductivity is also lowered, so that the heat absorbing pigment is preferably a carbon black having an average particle size of from 1 to 100 nm. When the conductive pigment contained in the heat-absorbing film layer of the surface-coated sheet of the present invention is aluminum powder and stainless steel powder, the conductive pigments are likely to hinder heat absorption, and those having such conductive pigments are added (example of the present invention) IV i5 and IV-16) have a tendency to decrease emissivity. The conductive pigment composed of the sheet metal Ni having an average particle diameter of 0.5 to 5 〇em and the chain metal Ni 10 is less likely to hinder heat absorption, and therefore is very suitable. However, since the mass ratio of the sheet metal Ni to the chain metal Ni is less than 〇.1 (Inventive Example IV-11), the conductivity is lowered, and the mass ratio of the sheet metal Ni to the chain metal Ni is more than 6 ( In the present invention, in the case of the example IV-14), the tendency to impede heat absorption is 'the emissivity is low, so the mass ratio of the sheet metal Ni/healthy metal Ni is preferably 0.1 to 6. If the conductive pigment is ferroniobium (inventive Example IV-17), it is more suitable because the emissivity does not decrease. The addition of the heat-absorbing pigment and the addition of only the iron (Inventive Example IV-19) is very preferable because of its high emissivity and excellent electrical conductivity. Further, when conductive carbon black is used as the heat absorbing pigment, it is more preferable because conductivity can be improved. The evaluation results of the surface-coated sheets having different heat-absorbing film layers were shown in Table 13. Further, any of Table 13 was a test result using a sample in which a heat-absorbing film of the same condition was applied to both sides of a non-metal plate. In the case where the film thickness is less than (inventive example IV_23), there is a tendency that the total emissivity is low, so that the film thickness is preferably 1 μm or more. Table 14 shows the results of heat absorption evaluation only in the case where the heat absorbing film layer was covered on one side and the other side was not coated. When only one side was covered, the heat absorbing film layer was covered on the outer side of the outer casing for covering the heat generating body which became the heat source (Comparative Example IV-31), and the thermal property was almost ineffective and unfavorable. (Example V) Hereinafter, the method for producing the heat-absorbing coated sheet used in the experiment will be described in detail. The heat-absorbing film coatings shown in Table 4 were coated on a ceramic plate of oxidized (4) using a bar coater, and allowed to dry in a county for 24 hours. Details of the finished surface coated panels are shown in Table 15. The surface coated sheets shown in Table 15 were all covered with the same type of heat absorbing 15 film layer on both sides under the same conditions. Hereinafter, details of the evaluation test of the prepared surface treatment plate will be described. 1) The emissivity measurement test of the surface coated plate was the same as in Example IV. 2) The heat absorption measurement test 20 of the surface coated sheet was the same as in Example IV. 3) The impact resistance test of the coating film was the same as in Example IV. 4) Observation of the state of the endothermic coating The evaluation of the film coating of each of the heat absorbing thin films applied to the ceramic plate was carried out in the same manner as in Example II. 5) Appearance of endothermic film The appearance of the film covered on the Taoshen board was visually observed and evaluated in the same manner as in Example II. 5 Hereinafter, the details of the evaluation results of the prepared surface coated sheets will be described.

The evaluation results are disclosed in Table 17. The refrigerator of the present invention is intended to cover the inner surface of the metal outer panel with a heat absorbing film for the purpose of lowering the temperature of the interior 5 of the refrigerator, and the heat absorbing film is 80. (: The number of waves measured at a temperature below 200 C is 600~300^^, and the total emissivity in the region is 0.70 or more. Inhalation + ^ ”, the emissivity of the secondary decidua is less than 〇.7 The latter (83 1313641 玖, invention description comparative example VII-17, VII-18, VII-20, VII-21), the internal temperature of the refrigerator is not much different from those of the conventional type, and thus is not suitable. In the heat absorbing film of the outer panel of the refrigerator of the present invention, if the solid content of the binder is contained in an amount of 10 to 150 parts by mass per 5 parts by mass, the emissivity of the heat absorbing film becomes 0.70 or more. Further, it is more preferable that the amount of carbon added is less than 10 parts by mass (Comparative Examples VII-17, VII-18, VII-20) or that the heat-absorbing film is not covered (Comparative Example νπ_21), and the emissivity is less than 0.70. Further, when the amount of carbon added is more than 15 parts by mass (Comparative Example VII-19), the workability is poor, which is not preferable. 10 The conductive pigment is added to the heat absorbing film of the refrigerator outer panel of the present invention. It imparts conductivity, so when it is assembled in the refrigerator, it is not easy to generate static electricity, and there is no dust caused by static electricity. The adhesion problem is more suitable. When the conductive pigment is not added (Inventive Example VII-6, VII-8, VII-9), the conductivity is poor. The heat absorbing film of the refrigerator outer panel of the present invention is added with rust prevention. The pigment 15 (inventive Example VII_7 'VII-8, VII-9) is excellent in corrosion resistance, and is more preferable, especially in the case of adding bismuth iron (Inventive Example VII-7), and having conductivity in addition to corrosion resistance. It is more suitable, and is more suitable. In the endothermic film of the outer panel of the refrigerator of the present invention, the solid content of the binder containing the mass of the binder is 1 to 20 parts by mass and the particle diameter is less than 0.1 20 &quot; Carbon and a particle size of 1 to 140 parts by mass 〇.1" m or more carbon of 50# m or less, and a particle diameter of less than 0.1 m and a particle size 〇丨&quot;m or more 5 〇&quot; m or less of carbon In the total of 1 to 15 parts by mass (inventive example vil-22, VII-23), it is more preferable because a large amount of carbon is added to the heat-absorbing film, but the viscosity of the heat-absorbing coating is not easily increased. 1313641 发明, the invention describes the outer panel of the refrigerator of the present invention before the heat absorbing thin enamel is applied. The treatment has excellent adhesion and workability, and is more suitable. If the chemical conversion treatment is not carried out (Example VII-12 of the present invention), the adhesion and the workability are inferior. Further, the type of the chemical conversion treatment may be any, but (5) In the case of using a chromate treatment (Example VII-11 of the present invention), the non-chromate treatment is more suitable from the viewpoint of environmental protection. (Example VIII) Hereinafter, the heat absorption for the experiment will be described in detail.

As shown in Tables 19 and 20, the surface-coated sheet of the present invention is obtained by covering a heat-absorbing film layer having a dry film thickness of 1 m or more to obtain a surface-coated sheet having high heat absorbability, and the heat absorbing property. The film layer contains 1 to 20 parts by mass with respect to 100 parts by mass of the resin solid content, and the particle diameter is less than 0·1 10 from 111 carbon and 1 to 140 parts by mass. ί.ίμιη above 50&quot; The total amount of carbon having a particle diameter of less than 0.1 μm and carbon having a particle diameter of 0.1 μm or more and 50 μm or less is 10 to 150 parts by mass. 86 1313641 玖, Invention Description 6 1 « 瑶 η Appearance 〇〇〇〇〇〇〇〇 &lt;3 〇〇〇〇〇〇〇X 〇〇 Endothermic state of the heat-absorbing paint | 〇〇&lt;] 〇〇〇〇〇〇 〇〇〇〇〇&lt;] &lt;〇〇〇# XXXXXXXXXXXXXXXXX 〇X 1» S?r 〇〇〇〇〇〇〇X 〇〇〇〇〇〇XX 〇〇〇〇〇〇〇〇〇〇〇〇XX 〇XX 〇〇〇XX CQ | 0.81 | rH | 0.77 1 c〇§ 丨0.73 | 0.65 m GO 00 s 1 0.65 1 CTi 00 ! 0.88 CO CO •^3» 03 l〇Μ 〇〇〇〇ο 〇〇ooo O c&gt; 〇Ξ ε β B ε ε SS g ε assgge ε Ξ s 实 1爻=1 L〇3. to LO a. in d LO a.

The alkaline water is sprayed on the surface of the heat absorbing film layer. Let 15 test time be 500h. The evaluation method of the coating film of the cross section is evaluated as 〇 when the maximum foaming width on one side of the cross section is less than 2 mm, Δ when it is greater than or equal to 2 mm and less than 5 mm, and X when it is 5 mm or more. In addition, the above-mentioned water spray test was also carried out on the flat plate on which the burrs (hairs) at the time of cutting were produced on the evaluation surface side (becoming the upper burrs) of the coated steel sheet 2, and it was observed that it was started from the end surface. The foaming width of the film. The evaluation method of the end face was evaluated as 〇 when the blister width of the end face was less than 2 mm, Δ when it was greater than or equal to 2 mm and less than 5 mm, and evaluated as X when it was 5 mm or more. 92 1313641 发明, description of invention 7) Conductivity test The same as Example I. The evaluation results of the influence of the added pigment type and the added amount on the heat absorbing film layer covering the aluminum alloy sheet are shown in Table 22. 5 It is understood that the aluminum alloy sheet of the present invention (Examples Χ-1 to Χ-25 of the present invention) has a wave number of 60 (^3000 (:111-1), and the total emissivity is 0.70 or more in the region of 80 C. Therefore, the comparative examples χ26 and χ27, which have a lower emissivity than 〇7〇, have high heat absorption and are suitable as a casing for the heating element. The heat absorbing film layer of the aluminum alloy sheet of the present invention is composed of 1 〇〇 mass. The binder solid content, 10 to 150 parts by mass of the heat absorbing pigment, and 1 to 150 parts by mass of the conductive pigment are excellent in workability and electrical conductivity, so it is more suitable for adding "heat absorbing material". If the amount is less than 10 parts by mass (Comparative Example 26 26), the emissivity is less than 〇7, and the heat absorbing property is poor, so that it is not suitable for 15. The amount of the heat absorbing pigment added is more than 150 parts by mass (Example of the present invention - 5) 'There is a high emissivity, but the workability such as the bendability and the press formability is lowered, so it is preferably 150 parts by mass or less. If the amount of the conductive pigment added is less than 丨 by mass (Example χ8 of the present invention), In this case, since it is impossible to ensure conductivity, it is preferably 1 part by mass or more. When the amount of the conductive pigment added is more than 15 parts by mass (Comparative Example 2727), since the conductive pigment impairs heat absorption, the emissivity becomes less than 〇7, and the heat absorbing property is poor, and the processability of the film layer is also large. It is not suitable to reduce it. 匕3 The heat absorption of the heat absorbing film layer of the alloy sheet of the present invention 93 1313641 玖 The inventive pigment is a carbon black having an average particle diameter of 1 to 1 〇〇 nm, and the foregoing conductive The pigment is composed of a sheet metal Ni and a chain metal having an average particle diameter of 55 to 50 μm, and the mass ratio of the sheet metal Ni/chain metal Ni is 0.^6, due to heat absorption and It is more preferable because it has more excellent electrical conductivity. If the heat absorbing pigment has a larger particle diameter such as an anomalous powder and a graphite powder (X-6 and X-7 of the present invention), the emissivity is low and the heat absorption is large. The pigment hinders the conductive effect of the conductive pigment and lowers the conductivity. Therefore, the heat-absorbing pigment is preferably carbon black having an average particle diameter of 2,000 nm. The conductivity of the heat-absorbing film layer included in the aluminum alloy sheet of the present invention. 10 if the pigment is aluminum powder and stainless steel powder, the conductivity The pigment easily hinders the heat absorbing property. The emissivity of the conductive pigment (in the present invention χ15 and xb) is lowered. The sheet metal Ni and the chain metal Ni having an average particle diameter of 0.5 to 50 μm are not easily hindered. It is very suitable because it has a heat absorbing property. However, since the mass ratio of the sheet-like 15 metal Ni to the chain metal Ni is smaller than 〇] (Example χ 11 of the present invention), the conductivity is lowered, 'sheet metal Ni and chain metal Ni If the mass ratio is more than 6 (inventive example χ_ΐ4), the heat absorbing property is hindered and the emissivity is low. Therefore, the mass ratio of the sheet metal Ni/chain metal Ni is preferably 〇1 to 6. When the conductive pigment is ferroniobium (Example χ_17 of the present invention), the emissivity is not lowered by 20, and the corrosion resistance of the aluminum alloy sheet of the present invention is also improved, so that it is more suitable. The addition of the heat absorbing pigment and the addition of only the strontium iron (Example χ 19 of the present invention) are very preferable because they have a high emissivity and are excellent in electrical conductivity and corrosion resistance. Further, when conductive carbon black is used as the heat absorbing pigment, it is more suitable because it can improve conductivity by the description of the invention. In the heat-absorbing thin film layer of the alloy sheet of the present invention, in addition to the heat-absorbing pigment and the conductive pigment, an anti-iron pigment is added (Examples -22 to x_25 of the present invention), and it is more preferable because it is excellent in durability. The evaluation results of the aluminum alloy plate with different thickness of 5 \ g absorbent film layer revealed Jie 22 . Since the film thickness is less than 1/m (the χ_28 of the present invention), the total radiation rate is low, and if it is more than 50/zm, the workability of the film layer is lowered, so that the film thickness is preferably 1 to 50 #m. Industrial Applicability According to the present invention, it is possible to establish a heat-dissipating technique that generates heat generated inside a household electrical appliance that is a component of a heat source that has a large number of internal motors and electronic components.
