Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foamed decorative material suitable for use as a ceiling material or a wall material in a building such as a house. The present invention relates to a foamed decorative material having improved workability.

[0002]

2. Description of the Related Art Conventionally, a foamed resin layer formed from a thermoplastic resin composition containing a foaming agent has been applied on a base material such as paper, cloth or plywood, and if necessary, an appropriate pattern or It is well known that a foamed decorative material appropriately formed with a concavo-convex pattern or the like is used for various applications as described above.

[0003] Such foamed decorative materials include, for example, azodicarbonamide (AD) added to a thermoplastic resin such as a polyvinyl chloride resin.
CA) and other appropriate additives such as, for example, a plasticizer, a colorant, a filler, a stabilizer, and a diluting solvent, if necessary, to form a sol, paste, or emulsion. A flowable coating composition, which is applied in the form of a thin film on the surface of an appropriate substrate, dried to form a foamable thermoplastic resin composition layer, and further printed and heated with an appropriate pattern It is most commonly manufactured by forming an embossed pattern by foaming and embossing.

As the foaming agent to be mixed with the resin composition for forming the foamed resin layer, various organic and inorganic foaming agents are known, but a relatively low foaming agent which does not deteriorate the thermoplastic resin to be foamed is known. In order to obtain sufficient foaming characteristics at a temperature, an organic foaming agent having a relatively low thermal decomposition temperature and a high foaming efficiency is mainly used. Above all, azo organic blowing agents represented by azodicarbonamide (ADCA),
It is most widely used as an inexpensive and excellent foaming agent.

By the way, many organic foaming agents including the azo organic foaming agents described above are generally colored. Therefore,
A foamable resin composition containing these organic blowing agents generally shows a hue determined by the type and amount of the organic blowing agent added. However, the organic foaming agent is thermally decomposed and gasified and becomes colorless by the subsequent thermal foaming. Therefore, the hue of the foamed resin layer after the thermal foaming should ideally not be influenced by the hue of the compounded foaming agent. It is.

However, in reality, the foaming agent is not ideally completely decomposed in the heating foaming process, but remains undecomposed to some extent, and the hue of the foaming agent in the foamed resin layer is not small. The fact is that it has survived. This is because if the foaming agent is heated sufficiently until it is completely thermally decomposed, the plasticization or melting of the resin due to heat progresses too much, so that the cells (bubbles) formed by angled foaming are crushed, and foaming occurs. Since the magnification decreases, in order to obtain a product with good performance, it is necessary to stop heating and foaming while leaving some undecomposed foaming agent at the time when the foaming ratio is maximized. Because there is no.

The residual hue of the foaming agent causes not only a problem that the hue of the product deviates from an ideal hue but also a troublesome problem of unevenness of the hue of the product. That is, uneven heating of the heating device for heating and foaming,
This is because the amount of the foaming agent remaining undecomposed in the foamed resin layer due to uneven feeding of the product in the heating device is not always constant in the width direction or the feeding direction of the product.

[0008] Such a problem can be naturally solved by using a colorless foaming agent even in an undecomposed state as a foaming agent. In fact, almost colorless blowing agents such as, for example, p, p'-oxybisbenzenesulfonylhydrazide (OBSH) are also known. However, these colorless or nearly colorless blowing agents are very special,
A is very expensive compared to general-purpose foaming agents such as A, and is not always satisfactory in terms of foaming performance. Therefore, it cannot be said that the above problems can be solved at once. Was.

As another solution, a method in which a coloring agent such as a pigment is added in a large amount to the foamable resin composition to positively color the foamable resin composition to reduce the coloring effect of the foaming agent can be considered. However, this method may be effective when aiming for a foamed decorative material of a dark color system, but when manufacturing a foamed decorative material of a light color system such as white, titanium may be used. Even if a white pigment such as white is used, its concealing ability is naturally limited, and the coloring effect of the foaming agent cannot always be suppressed.In addition, the addition of a large amount of the coloring agent makes the resin brittle, so that the surface strength and There is also a problem that the expansion ratio is restricted due to the balance and the foaming feeling and the embossing suitability are deteriorated.

[0010]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems in the prior art, and an object of the present invention is to provide a hue by a foaming agent which remains unfoamed. An object of the present invention is to provide a foamed decorative material which is less likely to cause displacement and hue unevenness, can be stably produced, and can secure a sufficient foaming feeling and embossability.

[0011]

The foamed decorative material of the present invention comprises:
A foam decorative material comprising a surface resin layer formed from a thermoplastic resin composition containing at least a coloring agent, on a base foamed resin layer formed from a thermoplastic resin composition containing at least a foaming agent.

[0012] In particular, in the above foam decorative material, the base foamed resin layer is a thermoplastic resin in which 4 to 10 parts by weight of a foaming agent and 0 to 20 parts by weight of a coloring agent are blended with respect to 100 parts by weight of the thermoplastic resin.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION The foamed decorative material of the present invention is constructed by laminating a base foamed resin layer 2 and a surface resin layer 3 on a base material 1 sequentially as shown in FIG. Here, the base foamed resin layer 2 is formed from a thermoplastic resin composition containing at least a foaming agent and, if necessary, a colorant, while the surface resin layer 3 is made up of at least a colorant. It is formed from a thermoplastic resin composition containing a blowing agent, if necessary. Importantly, the mixing ratio of the coloring agent to the thermoplastic resin composition forming the base foamed resin layer 2 is smaller than the mixing ratio of the coloring agent to the thermoplastic resin composition forming the surface resin layer 3. Further, the compounding ratio of the foaming agent to the thermoplastic resin composition forming the surface resin layer 3 needs to be set smaller than the compounding ratio of the foaming agent to the thermoplastic resin composition forming the base foamed resin layer 2.

As described above, the foamed decorative material of the present invention comprises a resin having a smaller amount of the foaming agent and a larger amount of the coloring agent on the base foamed resin layer 2 containing a sufficient amount of the foaming agent. Since the surface resin layer 3 composed of the composition is provided, the surface resin layer 3 has a small amount of the foaming agent, so that the coloring by the foaming agent remaining after foaming is small, and hue unevenness is hardly generated. Since the blending amount of the coloring agent is large, even if hue shift or hue unevenness occurs in the base foamed resin layer 2, it can be effectively concealed. Therefore, a sufficient amount of the foaming agent is added to the base foamed resin layer 2 without much concern for coloring by the foaming agent, and the amount of the coloring agent that is a factor of suppressing the expansion ratio is reduced, and a sufficient magnification is obtained. Can be foamed. In this way, it is possible to realize a foamed decorative material which has a sufficient foaming feeling and embossing suitability as a whole, has less hue shift and hue unevenness due to a residual foaming agent, and can be stably produced.

An embodiment of the foamed decorative material of the present invention is shown in FIG.
However, the present invention is not limited to the example shown in FIG. For example, the base material 1 is not necessarily an essential component of the present invention, and may have a two-layer structure of the base foamed resin layer 2 and the surface resin layer 3 in which the base material 1 is omitted (FIG. 2). Conversely, constituent layers other than those described above can be appropriately added, and one or two foamed or non-foamed intermediate layers 4 are provided between the base material 1 and the base foamed resin layer 2.
More layers can be provided (FIG. 3). Further, as in the case of general wallpaper or the like, a picture layer 5 may be provided on the surface resin layer 3 and an embossed pattern 6 may be provided (FIG. 4). Further, a transparent or translucent surface protective layer 7 may be provided (FIG. 5).

The material of the base material 1 is not particularly limited as long as it has heat resistance to such an extent that the base foamed resin layer 2 (and the surface resin layer 3) is not deformed by heat at the time of heating and foaming. Specifically, papers such as inorganic paper or flame-retardant paper, cloth such as woven or non-woven fabric, synthetic resin film or sheet, wood veneer such as wood veneer, plywood or fiberboard, gypsum board or calcium silicate An appropriate material may be selected from an inorganic plate such as a plate, a metal foil or a metal plate, or a laminate or a composite thereof, depending on the intended use.

The constituent materials of the base foamed resin layer 2 and the surface resin layer 3 are basically substantially the same, and a foaming agent, a coloring agent, a plasticizer, a stabilizer, a filler, a foaming timing are added to the thermoplastic resin. It is formed from a resin composition in which various additives such as a regulator and a diluting solvent are appropriately blended. Here, the thermoplastic resin to be used may be the same or different between the base foamed resin layer 2 and the surface resin layer 3, and specifically, for example, a polyvinyl chloride resin, a polyolefin resin, a vinyl acetate resin A resin, a urethane resin, a polyester resin, an acrylic resin, or a combination of two or more of these resins, a mixed resin, or the like can be used. When a polyvinyl chloride resin is used, the polymerization degree is 600 to 1600.
It is preferred to use a range of resins.

Examples of the foaming agent include azo foaming agents such as azodicarbonamide (ADCA) and azide foaming agents.
One or more types are appropriately selected from organic blowing agents such as hydrazide-based blowing agents such as p, p'-oxybisbenzenesulfonylhydrazide (OBSH) and inorganic blowing agents such as sodium hydrogencarbonate and ammonium carbonate. Can be used.

The mixing ratio of the foaming agent is not particularly limited as long as the above-mentioned restriction on the relationship between the two layers is obeyed.
Generally, the resin composition for forming the base foamed resin layer 2 contains a thermoplastic resin 100 in order to obtain a sufficient foaming effect.
It is preferably about 4 to 10 parts by weight based on parts by weight, while the resin composition forming the surface resin layer 3 is preferably kept at about 0 to 6 parts by weight in order to suppress coloring by a residual foaming agent.

However, when no foaming agent is added to the resin composition forming the surface resin layer 3, the surface of the decorative material is non-foamed, although the physical properties such as scratch resistance are excellent. This is not always sufficient in terms of feeling, and is also disadvantageous in terms of the overall expansion ratio including the base foamed resin layer 2. Therefore, the resin composition for forming the surface resin layer 3 contains 1 part by weight or more of a foaming agent with respect to 100 parts by weight of the thermoplastic resin, and preferably ranges from 1 to 6 parts by weight.

As the colorant, any colorant having at least heat resistance that does not cause discoloration or fading at the heating and foaming temperature and weather resistance required according to use conditions may be used. Any one can be selected and used. Specifically, inorganic colorants such as titanium oxide, zinc oxide, iron oxide, and carbon black, and organic colorants such as phthalocyanine, quinacridone, and isoindolinone can be used. When a white or pale color is desired, a white inorganic pigment such as titanium oxide or zinc oxide is mainly used.

The compounding ratio of the coloring agent is not particularly limited as in the case of the foaming agent, as long as the above-mentioned restriction on the relationship between the two layers is adhered to. In order to prevent embrittlement of the resin and foam the resin at a sufficiently high magnification, it is preferable that the amount of the resin composition is not more than 20 parts by weight based on 100 parts by weight of the thermoplastic resin.
On the other hand, the resin composition for forming the surface resin layer 3 has 100 parts by weight of a thermoplastic resin in order to ensure sufficient concealment of the base foamed resin layer 2 and to sufficiently dilute the coloring effect of the residual foaming agent. At least 10 parts by weight based on the weight of the mixture. If the upper limit is too large, the resin becomes brittle and causes a decrease in surface strength.
The range is preferably 30 parts by weight or less based on parts by weight.

Examples of the plasticizer include phthalate ester plasticizers such as dioctyl phthalate (DOP) and diisononyl phthalate (DINP), adipate ester, trimellitate, and phosphate ester. Conventionally known plasticizers such as polyester and polyester can be appropriately used. Stabilizers such as organic compound-based cell preparation agents and heat stabilizers; fillers such as calcium carbonate, magnesium carbonate, aluminum hydroxide, and inorganic fillers such as magnesium hydroxide; foaming timing regulators such as zinc , Calcium, barium, sodium, etc., any conventionally known additives can be appropriately added.

As the method for forming the base foamed resin layer 2 and the surface resin layer 3, any conventionally known coating method such as a knife coating method, a comma coating method, a lip coating method, a die coating method, a roll coating method, or the like is employed. can do. There is no particular limitation on the order of formation, the time interval for formation, and the like. That is, the base foamed resin layer 2 and the surface resin layer 3 may be sequentially coated on the base material 1, or the surface resin layer 3 and the base foamed resin layer 2 may be sequentially coated and formed on release paper in advance. It may be later peeled off from the release paper, and may be laminated with the base material 1 before or after the release, or alternatively, the base foamed resin layer 2 may be coated on the base material 1 and the surface resin layer 3 may be formed on the release paper by coating. The surface resin layer 3 may be peeled off from the release paper, and the surface resin layer 3 may be laminated on the base foamed resin layer 2 before or after the peeling. When two layers are formed by coating, one layer may be sufficiently dried after the coating is formed, and then the other layer may be formed by coating, or simultaneously or without a drying step. Two layers may be continuously formed by coating.

Although the basis weight of each layer is not particularly limited, the basis weight of the surface resin layer 3 is preferably at least 20 g / m ² or more in order to secure sufficient hue stability. since inferior in terms of the overall expansion ratio and foam feeling too, amount may be 120 g / m ² or less. The basis weight of the base foamed resin layer 2 is appropriately designed in consideration of the intended use and the desired feeling of foaming and embossing depth. For example, in the case of wallpaper, it is about 80 to 300 g / m ² . A range is most preferred.

When the intermediate layer 4 is provided between the substrate 1 and the base foamed resin layer 2, the material of the intermediate layer 4 is not particularly limited.
Generally, it is appropriately selected from those listed as the material of the base material 1 or those listed as the material of the base foamed resin layer 2 and the surface resin layer 3. The laminating method is, for example, a dry laminating method, a wet laminating method, a polysand laminating method, a heat laminating method, or the like if the material is the same as that of the base material 1. A law or the like can be adopted.

The most typical form of the foamed decorative material of the present invention is in the form shown in FIG. 4, and is most typically manufactured according to the process shown in FIG. That is, first, the base foamed resin layer 2 is formed on the base material 1 (FIG. 6A) (FIG. 6B), and then the surface resin layer 3 is formed (FIG. 6B).
(C)) After drying under a temperature condition such that heating and foaming are not performed, a pattern layer 5 is printed and formed on the surface resin layer 3 (FIG. 6).
(D)) After heating and foaming, the surface is provided with an embossed pattern 6 by embossing to complete the foamed decorative material of the present invention (FIG. 6).
(E)).

The pattern layer 5 is formed by using an appropriate printing ink, for example, a gravure printing method, an offset printing method, a screen printing method, an ink jet printing method, an electrostatic printing method, a transfer printing method, etc., as in the case of the conventional foam decorative material. Can be formed according to an appropriate printing method. The type of the picture pattern formed by the picture layer 5 is arbitrary as desired, for example, a wood pattern, a stone pattern, an abstract pattern, a geometric pattern, and the like. Further, as a printing ink for forming the picture layer 5, foaming suppression which acts on a foaming agent mixed in the resin composition for forming the surface resin layer 3 and / or the base foamed resin layer 2 to raise or lower the thermal decomposition temperature. When a printing ink containing an agent or a foaming accelerator is used, the uneven pattern 6 synchronized with the picture pattern constituting the picture layer 5 can be obtained only by the heating and foaming step without going through the subsequent embossing step (Chemical Embossing method).

Except for the case of the above-mentioned chemical embossing method, embossing is performed by using a metal embossing plate or embossing roll having a surface having a concavo-convex pattern obtained by inverting the concavo-convex pattern 6 to be formed. By a mechanical embossing method (flat pressure embossing method or roll embossing method) in which the surface of the surface resin layer 3 is pressed by a flat pressure type or a rotary type at a lower temperature and at a temperature at which the resin is sufficiently thermoplasticized. Is the most common. There is no particular limitation on the type of the concavo-convex pattern 6 formed by embossing. For example, a pattern that is synchronized with or similar to the pattern constituting the pattern layer 5 or a gloss that is not directly related to the pattern, such as a suede tone or a hairline tone. The material is appropriately selected as desired from a material tone such as a matte tone, a Japanese paper tone, or a grain tone. Further, as a special case, the colorant is attached to the entire surface after embossing, and the excess colorant is wiped off (wiping method), or the colorant is attached to the convex portion of the embossing roll to perform embossing ( In some cases, the concave portions of the concavo-convex pattern 6 are colored by the valley print method).

A transparent or translucent surface protective layer 7 may be provided for the purpose of protecting the picture layer 5 from abrasion and contamination and maintaining the design for a long period of time. The surface protective layer 7 may be formed of the same thermoplastic resin as that mainly composed of the surface resin layer 3. However, in order to obtain higher surface properties, for example, a urethane-based resin or an amino-based resin is used. And a cross-linking reaction-curable resin such as an ionizing radiation-curable resin such as a (meth) acrylate-based resin. When a thermoplastic resin is used, a coating method similar to the case of the surface resin layer 3 or the like or a film laminating method is generally used when a thermoplastic resin is used. It is common to emboss. On the other hand, when a cross-linking reaction curable resin is used, it is generally applied and formed by a roll coating method, a gravure coating method, a spray coating method, or the like. The formation time may be before or after the embossing process. In particular, when performing the wiping or the valley print described above, the embossing process or the wiping process is performed for the purpose of protecting the coloring layer in the concave portion. Is generally formed after.

Various additives can be added to the surface resin layer 3 and / or the surface protection layer 7 for the purpose of improving surface physical properties or imparting special functions. Specifically, for example, a benzotriazole-based ultraviolet absorber or a hindered amine-based light stabilizer for the purpose of improving weather resistance (light resistance), a gloss modifier such as silica for the purpose of adjusting the surface gloss, or the like. , A lubricant such as wax for the purpose of improving surface lubricity, a lubricant comprising high hardness particles such as alumina for the purpose of improving scratch resistance and abrasion resistance, and a purpose of improving contamination resistance Hazardous chemicals scavengers or decomposition catalysts (photocatalysts etc.) for the purpose of trapping or decomposing and removing harmful chemicals such as formaldehyde and the like in silicone air or silicone resin in indoor air, and organic or Inorganic antibacterial agents and the like can be mentioned.
