Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood-like frame material suitable for, for example, a door frame or a decorative frame in a house.

[0002]

2. Description of the Related Art As a door frame or a decorative frame in a house, a product formed by processing or combining wood into a predetermined sectional shape has been used for a long time, but the processing and combination are complicated, Due to a complicated cross-sectional shape or the like, in recent years, a resin such as vinyl chloride is used as a material, and this is molded by extrusion or injection molding. That is, by using a resin, many products can be molded in a short time even if they have a complicated cross-sectional shape.

By the way, the resin door frame and the decorative frame (hereinafter collectively referred to as frame members) have a feeling of strangeness in the state of the material as they are, particularly in a wooden house or the like. There is a method of giving a woody texture by making it have a color similar to, or by pasting a sheet with a woody pattern on its surface.

However, even by such means, the surface of the resin frame material is not made to be natural wood-like,
Furthermore, since the material is 100% resin, it is undeniable that it gives a poor impression. Therefore, in resin molding,
In recent years, attempts have been made to add a desired amount of wood powder and a pigment corresponding to a desired color tone to a resin material to obtain a desired woody resin molded product similar to natural wood.

Here, the wood powder added to the resin material has been improved in order to improve the dispersibility at the time of compounding with the resin material and to prevent the generation of wood acid gas in the molding machine during molding. Many of them are known, and a typical example thereof is a particle board surface-polishing powder which has been cured with a urea resin. The main characteristic of the surface-polished powder of this particle board is that it is fine and has a particle shape with few cilia on the surface and good lubricity. Since it is fine and has good lubricity, it is a wood flour having a good dispersibility and mixing property with respect to a powdery granular resin material.

On the other hand, wood powder obtained by directly pulverizing wood into fine powder has poor pulverization efficiency regardless of whether it is obtained by a dry pulverizer or a wet pulverizer.
Even after a long-time crushing process, there was a disadvantage that a large amount of wood powder with a large particle size remained in the crushed powder. In addition, this wood powder does not form a grain shape, and most of them are fibrous, and even if the particle diameter measured on the short diameter side is several microns, the long diameter side is long in a cilia shape, and therefore, the resin material When mixed and used, the wood powders are often entangled with each other to form an aggregated state, and there is a disadvantage that they are not uniformly dispersed in the resin material.

Further, since the particle size of the crushed wood powder is extremely varied, it is easy to cause molding distortion and the like in the molded resin product, and the mechanical strength is partially different. It was

Therefore, due to such inconvenience, it is said that the wood powder added to the resin material has a limitation in terms of composition, color and quality control, which is obtained by directly pulverizing wood into fine powder. Is there.

[0009]

However, in the resin molded product obtained by the above-mentioned conventional method, even if the surface polishing powder of particle board is used as the wood powder to be added, this surface polishing powder is It does not have uniform wood characteristics due to differences in material characteristics, and because the particle size tends to vary due to differences in the cutting means, for example, the mesh of sandpaper used, the resin molded product itself is also uniform. In reality, it is not possible to obtain a wood-like material, and it is the current situation that wood powder obtained by directly pulverizing wood into fine powder and drying it must be used.

When a wood-like frame material is molded as the resin molded product by an extrusion molding method or an injection molding method, a pigment having a color tone which gives a woody texture is naturally added to the resin material in advance.
In many cases, this pigment is not uniformly dispersed in the resin material, so that it is difficult to obtain a product having a desired color tone, and there is a disadvantage that color unevenness occurs on the surface.

[0011]

The present invention has been made to solve the above-mentioned problems, and the wood-like frame material according to claim 1 is subjected to grinding treatment and an inorganic pigment is applied to the surface thereof. It is characterized in that the carried cellulose-based fine powder particles are mixed with a resin material, and the mixture is molded into a predetermined frame shape by extrusion or injection molding.

The wood-like frame material according to claim 2 is characterized in that, in the wood-like frame material according to claim 1, a hollow portion is formed at a desired portion.

[0013]

According to the wood-like frame material of claim 1 of the present invention, since the cellulose-based fine powder particles carrying the inorganic pigment are ground, the conventional wood is directly pulverized into fine powder. Unlike fibrous, it has a small number of cilia on its surface and becomes granular, so there is no fuzz on the surface of the frame material,
Improves the feel. In addition, since the cellulose-based fine powder particles are not fibrous but are granular, when fibrous substances are compounded and dispersed, the fibrous parts are entangled to form a dumpling-like or cotton-like shape. As a result, the pigment-carrying fine particles themselves become extremely dispersible with respect to the forming resin, and therefore the obtained frame material also becomes a sufficiently uniform material. Furthermore, since the cellulose-based fine particles are not fibrous but have a granular shape, the expansion and contraction caused by adsorbing or releasing water (including moisture) and solvent like conventional fibrous wood powder is extremely small. Therefore, the wood-like frame material containing this becomes extremely excellent in dimensional stability.

Further, since cellulose fine powder particles which have been subjected to a grinding treatment and whose surface carries a pigment are used as an aggregate, the resin particles are hardly adsorbed and sucked by the fine powder particles, so that molding distortion is almost generated. Disappear. Further, in this wood-like frame material, since the cellulose-based fine powder particles carry the pigment, the heat resistance is improved as compared with before the loading, so that the cellulose-based fine powder particles such as wood powder are simply mixed. Compared to the case of molding, there is less heat effect during molding,
Therefore, alterations such as changes in color and shape are suppressed. Further, the surface of the cellulose-based fine powder particles is covered by supporting the pigment, thereby suppressing the release of glycine and formic acid contained in the fine powder particles at the time of molding. Molding defects due to release are prevented.

Further, in this wood-like frame material, the surface area of the cellulose-based fine powder particles is larger than that of the conventional wood powder because the surface area of the fine powder particles is carried by the pigment. And the degree of adhesion with resin increases. Furthermore, since the cellulose-based fine particles are blended, cutting with a saw and nailing can be sufficiently performed, and workability at the site is improved.

Further, in the wood-like frame material according to claim 2, the hollow portion can be used as a housing portion for housing equipment such as an electric wire cord and a power outlet, and this housing equipment is exposed indoors. The aesthetics of the room are maintained without doing so.

Further, the frame member 31 and the frame member 32 are joined by cutting the joint ends of both members at 45 degrees and joining the cut end faces with an adhesive or the like.

Now, the above-mentioned first and second frame members 31,
32 (hereinafter simply referred to as the door frame 21) is subjected to a grinding treatment, and the fine cellulose particles having a white inorganic pigment on the surface are mixed with a resin material, and the mixture is molded by extrusion or injection molding. It is manufactured by applying a paint on the surface.

The molding material will be described in detail below.

As the resin material of the molding material, vinyl chloride resin, phenol resin, polyethylene resin, polypropylene resin, ABS resin, polycarbonate resin, polyurethane resin and the like are used. Then, finely divided cellulosic powder carrying a white inorganic pigment is blended with this forming material resin, and if necessary known additives are blended and mixed, and then the mixture is extruded or injection molded to form the door frame 21. Is molded.

Here, as the cellulosic fine powder particles carrying the white inorganic pigment, coarsely pulverized materials of various plant cell bodies such as coarsely pulverized wood, coarsely crushed bacas and coarsely crushed rice straw are used. The one obtained by milling is used. In order to obtain a coarsely pulverized raw material, the chips and the like are pulverized by mechanical impact crushing to obtain coarsely pulverized powder having a particle size smaller than 150 mesh, preferably 120 mesh.
Here, for mechanical grinding, for example, an impeller mill (IM
P-250; manufactured by Seishin Enterprise Co., Ltd.) is preferably used.

The grinding treatment of the pulverized raw material is preferably performed by a ball mill shown in FIG. 4, for example. In this ball mill, a cooling jacket 2 is provided on the peripheral wall of an atmosphere-releasing mill body 1. Cooling water is circulated by supplying cooling water from a supply pipe 8 into the cooling jacket 2 and discharging it from a drain pipe 9. By doing so, the temperature inside the mill body 1 is set to a preset temperature, for example, 80 ° C. or lower.

Here, a motor 5 is arranged on the upper part of the mill body 1, and a rotor 4 for stirring the balls 3 in the mill body 1 is arranged on the bottom part of the motor 5. The rotor 4 is rotated by the drive of the motor 5 and agitates the ball 3 and the object to be ground to bring them into mechanical contact with each other. In addition, an outlet 7 that is opened and closed by a valve 6 is provided on the lower part of the cone of the mill body 1.
The material to be ground after the grinding processing can be discharged.

The balls 3 loaded in the mill body 1 of this ball mill are ceramic balls having an outer diameter of 3 mm to 5 mm,
In particular, it is preferable to use zirconia-based or alumina-based ceramic balls, and it is preferable to avoid using balls made of metal such as stainless steel and steel. This is because in the case of metal balls such as stainless steel and steel, crushed cellulosic powder such as wood powder may adhere to the surface of the balls, or the pulverized powder may be deteriorated due to heat generated by mutual contact between the metal balls. Because there is.

The dry ball mill may be either a closed type or an open type, but when the closed type is adopted, the mill is filled with an inert gas such as nitrogen gas before use. preferable.

In this ball mill, the balls used 3
The surface temperature of 90 ° C to 120 ° C,
The crushing / grinding process and the drying process of the crushed raw material material are performed so that the room temperature of the mill body 1 does not exceed 80 ° C. Here, regarding the temperature control of the balls 3 to be used, the capacity of the mill main body 1, the amount of the balls 3 charged into the mill main body 1, the material and size of the balls 3, and the charging temperature and amount of the charged pulverized material, It is performed by adjusting the stirring speed and the cooling amount by the cooling jacket 2 provided on the peripheral surface of the mill body 1 based on the water content.

The surface temperature of the ball 3 varies depending on the target material, but is 100 in the case of wood powder, for example.
C. to 120.degree. C. is preferable from the standpoint of grinding and grinding efficiency. However, when crushing / grinding requires a long time, it is preferably 90 ° C. to 100 ° C. from the viewpoint of preventing explosion. If there is a danger of a burst explosion during crushing / grinding, the oxygen concentration in the mill body 1 should be 15
The content is preferably within the range of%, and in that case, for example, a method of continuously supplying nitrogen gas into the ball mill may be adopted.

According to the crushing / grinding process by the ball mill, the internal temperature of the mill body 1 rises due to the frictional heat generated by the rotation of the balls 3, while the cooling water circulated in the cooling jacket 2 causes the mill to cool. By adjusting the temperature inside the main body 1 and the surface temperature of the balls 3 within the above-mentioned ranges, the raw material pulverized product is pulverized and simultaneously dried under a strong heating condition, whereby the desired particle size is obtained. The water content is adjusted to a range of, for example, 100 μm or less, and the water content is adjusted to 2.0% by weight or less.

Further, according to this treatment, the balls 3 come into contact with the pulverized raw material material charged in the coarse powder state,
The pulverized raw material that has come into contact with the balls 3 is ground in a state where the surface is broken, whereby the breaking and grinding are efficiently performed.

That is, the crushed raw material is crushed and mechanically crushed mechanically when it comes into contact with the surface of the ball 3.
Since it is ground and heated and dried at the same time, the water content is efficiently removed. Moreover, since the fibers in the pulverized raw material are subjected to expansion and contraction by being repeatedly subjected to heating and cooling, they are rapidly dried when they are separated from the balls 3, so that the tips of the fibers are The parts are efficiently ground by the balls 3, and as a result, ground cellulosic fine powder particles having an independent particle shape with less cilia on the peripheral surface can be obtained.

Then, the cellulosic fine powder particles thus obtained are classified to have a particle size in a desired range (for example, 1 to
10 μm, 10 to 20 μm, 20 to 50 μm, 50 to 1
00 μm) to obtain the cellulose-based fine powder particles of the present invention for supporting a white inorganic pigment.

As the white inorganic pigment to be carried,
Titanium oxide, lithopone, white carbon, calcium carbonate and the like can be used, but titanium oxide is particularly preferable for giving sufficient whiteness to each of the obtained frame materials 31 and 32. Further, the particle size of the white inorganic pigment is adjusted to be sufficiently smaller than that of the cellulose fine powder particles.

As a method of supporting the white inorganic pigment on the cellulosic fine particles, for example, the cellulosic fine particles and the white pigment are mixed, and the resulting mixed particles are dispersed in a gas phase to give an impact force. A method is adopted in which mechanical thermal energy mainly composed of is added to the particles, the cellulose-based fine powder particles are used as mother particles, and the pigment particles are supported on the peripheral surface of the mother particles.

As another method, mixed particles of cellulosic fine particles and a white pigment are charged by a ball mill as shown in FIG. 4 and ground again to give a white inorganic substance on the peripheral surface of the fine cellulose particles. A method of supporting pigment particles can also be adopted.

By carrying out such a carrying treatment, the white inorganic pigment particles 10 are carried on the peripheral surface of the cellulosic fine powder particles 11 in a biting state as shown in FIG. As the amount of the white inorganic pigment to be supported, the upper limit is an amount that overlaps the peripheral surface of the cellulosic fine powder particles as the base particles and covers the peripheral surface, but the lower limit is the desired white color of the door frame 21. It is appropriately determined according to the degree.

The pigment-supporting cellulose-based fine powder particles thus obtained have a color tone almost the same as the color tone of the white inorganic pigment, and the agglomeration of the supported fine powder particles occurs both during the production process and during the storage process. I was not able to admit.

Here, the amount of the supported fine powder particles mixed with the resin material to be formed is, for example, about 20 to 50 parts by weight of the supported fine powder particles with respect to 100 parts by weight of the resin when it is made of vinyl chloride resin.

As for the paint applied to the surface of the door frame 21, most of the paints used as the resin component can be used. Among them, urethane resin, acrylic resin, melamine resin, polyester resin and the like can be used. It is preferably used. As the pigment, a brown pigment such as iron oxide is used in order to give a woody appearance.

If it is desired to carry out all matting, a paint containing the above-mentioned ground fine cellulose particles may be used. Here, when the ground cellulosic fine particles are blended, the particle size of the cellulosic fine particles is 1 to 1
It is preferable to use one having a thickness of about 5 μm.

Prior to applying the paint to the wood-like board, the door frame 21 is subjected to the following processing as a pretreatment.

First, the surface to be coated of the door frame 21 is ground with a brush or baffle to roughen the surface to be coated and remove a part of the surface resin. Then, the wood-like plate material is smoothed by the grinding process as described above, and unnecessary fine irregularities generated at the time of molding are formed, and many fine scratches are formed.
The main purpose of this step is to eliminate the surface gloss, but especially when using a brush with a non-uniform tip, the surface roughening method becomes more or less strong, and color unevenness etc. may occur due to the coloring by coating described later. As a result, the wood texture can be further enhanced, and the penetration of the paint can be improved.

Further, in this case, the pigment-loaded cellulosic fine particles located on the surface by grinding the surface peels off the carried white inorganic pigment, and as a result, the inside of the cellulosic fine particles is exposed and the frame is exposed. Enhances the wood texture of the wood surface. In addition, such a grinding process causes unevenness in the whiteness of the surface, and when applying the paint to be described later, microscopically, there is a slight difference in the degree of suction of the paint and the degree of its paste. The wood-like frame material gives an even more wooden texture.

Then, the ground surface to be painted is decorated by embossing. This embossing process inserts a resin molding between the punch and the die to form a wood grain-like uneven pattern, or rolls the resin molding between embossing rolls to continuously form a wood grain like uneven pattern. Is the way to do it.

Next, a paint is applied to the embossed surface to make the wood grain pattern clear, and the excess paint on the coated surface is wiped off by a roll around which a nonwoven fabric or the like is wound. Here, as the coating of the coating material, a conventionally known coating method such as a spray gun spraying method or various fluid immersion methods can be adopted.

Further, a known top coat treatment is applied to the coated surface, and if necessary, the product is cut into a desired size to obtain a wood-like frame material as a product. It is needless to say that the cutting for obtaining the desired size may be performed in advance before the grinding treatment or further before the embossing.

As described above, a frame material obtained by subjecting the resin material to the fine cellulose particles having the inorganic pigment supported on the surface, which has been subjected to the grinding treatment, and molding the mixture by extrusion or injection molding. In this case, the surface is sufficiently white due to the white pigment supported on the surface, the color adjustment in the secondary processing becomes simple, and a beautiful woody appearance can be easily imparted. In addition, since the cellulose-based fine powder particles supporting the pigment have been subjected to grinding treatment, unlike the conventional powder obtained by directly pulverizing wood into fine powder, unlike the fibrous form, the surface has less cilia and is more granular. If the surface of the board is not fluffy, it will be soft to the touch.

Further, since the cellulose-based fine powder particles are not fibrous but have a granular shape, when fibrous substances are mixed and dispersed, the fibrous portions are entangled to form a dumpling-like or cotton-like shape. The individual particles are dispersed in an independent state, and thus the pigment-carrying fine particles themselves have extremely good dispersibility with respect to the forming resin, and thus the obtained plate material also has a sufficiently uniform material.

Further, since the cellulose-based fine powder particles are not fibrous but granular, they expand and contract due to adsorbing or releasing water (including moisture) and solvent like conventional fibrous wood powder. Therefore, the wood-like board material containing this has extremely excellent dimensional stability.

Further, since cellulose fine powder particles which have been subjected to a grinding treatment and whose surface carries a pigment are used as an aggregate, the resin particles are hardly adsorbed and sucked by the fine powder particles, so that molding strain is almost generated. Disappear. Further, in this frame material, since the cellulose-based fine powder particles support the pigment and thus the heat resistance is improved as compared with before the loading, simply by mixing the cellulose-based fine powder particles such as wood powder and molding. Compared with the case, the heat influence at the time of molding is small, and thus the deterioration such as the change of color and shape is suppressed. Further, the surface of the cellulose-based fine powder particles is covered by supporting the pigment, thereby suppressing the release of glycine and formic acid contained in the fine powder particles at the time of molding. Molding defects due to release are prevented.

Further, in this frame material, the surface area of the cellulose-based fine powder particles is larger than that of conventional wood powder because the surface area of the fine powder particles and the resin is larger than that of the conventional wood powder. The degree of adhesion with Further, at the time of molding, the resin containing fine cellulose particles of the present invention is excellent in fluidity as compared with the conventional resin mixed with wood powder, so that the extrusion molding pressure and the injection pressure can be set low.

Further, a surface treatment is applied to such a frame material,
In the door frame 21 manufactured by applying the paint after that, since the surface of the frame material after molding was subjected to the grinding treatment, the white inorganic pigment-carrying cellulose-based fine particles located facing the outer surface on the grinding surface are Since the pigment-carrying part is scraped and the inner surface of the cellulose fine powder particles faces the grinding surface, the feel of the frame material surface is soft, and the cellulose fine powder particles themselves are hygroscopic and have a rich wood texture. Becomes Further, by applying the coating material to the grinding surface facing the inner surface of the cellulose fine powder particles, the coating material is directly sucked into the cellulosic fine powder particles, whereby the coating material can be sucked and glued well.

Further, since the door frame 21 is blended with fine cellulose particles, it can be cut and nailed with a saw, and can be handled almost like wood. When used as a decorative material for homes, etc., installation such as on-site installation becomes extremely easy. In addition, since the door frame 21 contains the cellulose-based fine powder particles, the coating material is firmly applied to the plate material, and the product has a sufficiently uniform coating film without partial peeling.

When a paint containing finely ground cellulosic particles is used as the paint, unlike the conventional matte surface such as silica, there is no reduction in white turbidity and the color tone specific to the pigment used in the paint is obtained. And a matte colored surface is obtained. Furthermore, if a mixture of finely ground cellulosic fine particles is used as the paint, the dispersibility of the fine powder particles is good, so that the brown pigment that imparts a woody color tone is well dispersed in the paint, and thus obtained. The painted surface has no unnatural color unevenness and has a woody appearance with only a natural change in color tone due to embossing or the like.

Further, the door frame 21 has a plurality of hollow portions 4
Although 2, 43, 44, 45, and 46 are formed, these cavities 42 to 46 can be used as a housing portion for housing equipment such as an electric wire cord for power distribution and a power outlet.

As described above, by utilizing the cavities 42 to 46 as a housing portion for the above-mentioned housing equipment, the housing equipment is not exposed to the room, and the aesthetic appearance is maintained. When arranging the electric wire cords and the like, they can be put together in the hollow portion, which facilitates the power distribution work.

Further, when the cavity is formed in this way, the frame members can be joined accurately and easily.

The decorative frame 91 is fixed to the adjusting panel 28 in the same manner as the door frame 71 of the third embodiment.

In the door frame 71 and the decorative frame 91 of the third and fourth embodiments, the frame members 74 and 93 are the adjustment frame members 72 and 7.
3 and the adjustment frame member 92, the thickness of the adjustment panel 28 can be arbitrarily adjusted as long as it can be overlapped.

Now, also in each of the frame members of the decorative frame 61, the door frame 71 and the decorative frame 91 of the second, third and fourth embodiments, the material and the coating material are the same as the door frame of the first embodiment. 21 is exactly the same, and the effect is also the same. FIG. 11 shows the adjusting frame member 92 in the decorative frame 91 of the fourth embodiment.
The state where the electric wire cord 48 and the power outlet 49 are housed in the hollow portion 96 is shown.

In each of the above examples, each frame material is formed by mixing resin material with cellulose fine powder particles having a white inorganic pigment supported on the surface, and molding the mixture by extrusion or injection molding. However, the frame material itself may be made to be wood-like with the inorganic material supported on the cellulose-based fine powder particles as a color that produces a tea-like woody appearance, and a transparent lacquer or enamel may be used as a paint applied to the surface thereof.

Next, a specific manufacturing example will be described below.

(Production Example) Wood powder having a particle size of 30 μm to 100 μm and an average particle size of 50 μm, which was obtained by grinding by the ball mill method, was prepared and used as a white inorganic pigment having an average particle size of 5 μm. Supported titanium oxide. As the supporting method, the re-grinding treatment method by the ball mill described above was used.

Next, 30 parts by weight of the obtained supported fine powder particles were mixed with 100 parts by weight of vinyl chloride resin, and further, known materials as additives were appropriately mixed and mixed, and the obtained mixed powder was used. And extruded to form the frame material 93 of the fourth embodiment.
A plate material having a width of 60 mm, a thickness of 7 mm and a length of 10 m was obtained.

When the obtained plate material was visually observed and the feeling of touch was further examined, it was confirmed that the plate material had a uniform whiteness and the surface was soft and non-sticky.

Further, one surface of this plate material and the side end surfaces in the lengthwise direction were subjected to a grinding treatment with a buff roll to roughen the treated surface.

Next, the ground surface was further embossed with a punch and a die to form a grain-like uneven pattern.

Then, a general paint prepared in advance is applied to the embossed surface of the plate material with a spray gun to clarify the grain pattern, and the surplus paint on the coated surface is removed by a roll around which a non-woven fabric is wound. I wiped it off.

Further, a urethane-based or acrylic-based coating material was applied to the coated surface by a spray gun, a flow coater or the like to perform a top coat treatment, and the material was cut into a length of 5 m to obtain a material for the frame material 93.

The obtained frame material had a clear wood grain pattern, moderate color unevenness, and had a surface layer very close to that of natural wood because it was matte. In addition, since the coated surface was soft to the touch and there was no stickiness, it had a sufficient wooden texture.

As described above, according to the wood-like frame material of claim 1 of the present invention, since the cellulose-based fine powder particles carrying the pigment are ground, the conventional wood is directly treated. Unlike the fibrous material that is pulverized into fine powder, the surface of the frame material has few cilia and is granular, so that the surface of the frame material is not fluffy and has a soft texture that is rich in wood texture. Further, since the cellulose-based fine powder particles are not fibrous but have a granular shape, when dispersed individually, the pigment-carrying fine powder particles themselves also have extremely good dispersibility with respect to the forming resin, and thus were obtained. The frame material is also a sufficiently uniform material.

Further, when fibrous wood powder (cellulosic fine powder particles) which has not been subjected to conventional grinding treatment is incorporated into a resin as an aggregate, a treatment agent for alkali neutralizing the wood powder. Due to the effect of yellowing and further becomes a brown frame material, and molding strain occurs due to sucking resin, etc., but in the present invention, it is a cellulosic material which simply carries an inorganic pigment and is not subjected to alkali treatment. Since the fine particles are used, discoloration does not occur, and since the cellulose fine particles are not fibrous but granular, expansion and contraction is extremely small, so the wood-like frame material containing this has dimensional stability. It will be extremely excellent. Further, since the cellulose-based fine powder particles that have been subjected to the grinding treatment and the surface of which the pigment is carried are used as the aggregate, the adsorption and suction of the resin by the fine powder particles becomes extremely small, and the molding distortion hardly occurs.

Further, in this wood-like frame material, since the cellulose-based fine powder particles carry the pigment, the heat resistance is improved as compared with that before the loading. Compared with the case of blending and molding, the heat influence at the time of molding is small, and therefore deterioration such as change in color or shape is suppressed. Further, the surface of the cellulose-based fine powder particles is covered by supporting the pigment, thereby suppressing the release of glycine and formic acid contained in the fine powder particles at the time of molding. Molding defects due to release are prevented. Further, in this wood-like frame material, the surface area of the cellulose-based fine powder particles is larger than that of conventional wood powder due to the fact that the pigment is carried, and therefore the fine powder particles and the resin are contained in the frame material. The degree of adhesion with

Further, in the wood-like frame material according to claim 2, the hollow portion can be used as a housing portion for housing equipment such as an electric wire cord and a power outlet, whereby the housing equipment is exposed indoors. The aesthetics of the room are maintained without doing so.
