Abstract

PURPOSE:To make distinguishment of the title artificial wooden board material from natural board material impossible for a user by patterning the grain of wood on the surface of a reinforced layer to form unevenness and imparting the touch of the grain of wood and visually making these unevenness conspicuous. CONSTITUTION:FRP material has the gel coating layers 2 unevenly formed by patterning the grain of wood on the surfaces of the reinforced layers 1 wherein the reinforced material such as glass fiber has been laminated by adhesive resin. The gel coating layers 2 are formed of both the basic color gamuts 3 occupying large parts thereof and the added color gamuts 4 scattered according to the uneven grain pattern of wood. The basic color gamuts 3 are made to imitate fundamental color of natural wood. The added color gamuts 4 such as red, brawn, black, green are scattered in the basic color gamuts 3 according to the grain-like unevenness. Further the basic color gamuts 3 are complicatedly intermixed with the added color gamuts 4 and thereby the change in color tone is exhibited. Furthermore the basic color gamuts 3 exist even in the internal surface sides of the added color gamuts 4 and colorful depth is enhanced. In such a way, the gel coating layers 2 are formed by colorfully patterning the grain of wood in three dimensions on the surfaces of the reinforced layers 1 and thereby the title artificial wooden board material is so finely manufactured that it is not distinguished both visually and by touch from the natural board material.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides an FRP pseudo-wood board material 2 with a three-dimensional wood grain pattern that can be used as a table top, a decorative board for furniture, etc.
It is something to do.

[Conventional technology]

To manufacture an FRP product, a wooden mold is first made, an FRP mold is formed from this wooden mold, and a product is often manufactured using this FRP mold. At this time, in order to facilitate removal of the FRP mold from the wooden mold, fine irregularities on the surface of the wooden mold were smoothed as much as possible, polished with wax, and a release agent was applied. Therefore, manufactured FRP molds and products generally have smooth surfaces. In addition, to make products from FRP molds, the FRP molds are treated with wax and coated with a release agent.
Then, if necessary, apply gel coating by brushing or spraying, and after the gel coating resin has hardened, reinforcing materials such as glass fiber sheets are laminated with adhesive resin while impregnating and degassing the resin, until the resin has sufficiently hardened. The product was removed from the Here, the gel coat layer serving as the surface layer of the product is intended to beautify and protect the surface, and is generally colorless or monochrome.

[Problem to be solved by the invention]

By the way, when the FRP plate material formed by the above method is used as a table top plate, it has sufficient strength, but if it is smooth and monochrome, it tends to lack elegance. For this purpose, even if one attempts to form a fine wood grain pattern on the surface of an FRP product with three-dimensional irregularities, as is clear from the above conventional example, if there are fine irregularities, demolding is not easy and the wooden pattern is There was a risk of damage. Furthermore, it has been considered extremely difficult from a technical and economic point of view to apply color to match these three-dimensional irregularities.

Therefore, the present invention has been made based on the above-mentioned circumstances, and provides an FRP pseudo-wood board material 2 which has a three-dimensional wood grain pattern and is so precise that it is completely indistinguishable from a real wood grain board in appearance and feel.
The purpose is to provide a simple and economical manufacturing method.

[Means to solve the problem]

In order to achieve the above object, the FRP pseudo-wood board material 2 according to the present invention has unevenness imitating wood grain on its surface, and wood grain-like unevenness in the base color gamut that occupies most of the surface gel coat layer. It is characterized by a scattering of corresponding additive color gamuts.

In addition, the manufacturing method of the FRP pseudo-wood board material 2 according to the present invention is to form a wooden mold from a board material with three-dimensionally raised wood grains, thoroughly polish the surface of this wooden mold with wax and apply a mold release agent, and then gel coat it. , a reinforcing material is laminated, etc. to form an FRP mold with all the unevenness of the wood grain transferred from the wooden mold, and the FRP mold is waxed and coated with a release agent, and then gel coated with a base color resin to create the base tone. This method is characterized by partially removing the base color resin before solidifying the color resin, at the same time rubbing in the coloring resin for gel coating, gel-coating the base color resin again, and then laminating the reinforcing material and removing the mold. be.

Furthermore, in the above method, instead of the step of partially removing the base color resin before solidifying the base color resin and simultaneously rubbing in the colored resin for gel coat, the gel coat was performed by overlapping the colored resin before assimilating the base color resin. After that, you may perform the rubbing.

[For production]

FRP pseudo-wood board material 2 according to the present invention, the unevenness formed by imitating wood grain on the surface gives a three-dimensional wood grain feel when touched with the hand, and is also dispersed in the base color gamut corresponding to the unevenness. The added color gamut makes these unevenness visually stand out, so that the user can hardly distinguish it from a real board.

In addition, in the method for manufacturing FRP wooden boards according to the present invention,
By forming a wooden mold from a board with clearly visible wood grains, and thoroughly polishing the surface of this wooden mold with wax, and then applying a mold release agent, the fine wood grains can be removed without damaging the wooden mold. All the unevenness is transferred to the FRP mold as it is. Therefore, the unevenness of the wood grain is clearly transferred from the FRP mold to the product. Also, when forming the gel coat layer on the surface of the product, the base color applied to the uneven surface of the FRP mold. If the colored gel coat resin is rubbed in before the gel coat resin solidifies, part of the base color resin will be removed and the colored resin will enter there, and when the product is completed, the added color area will be on the surface of the base color area. Along with being scattered to correspond to the unevenness that imitates the wood grain,
The base color resin and the additive color resin are properly kneaded to produce areas with continuously changing subtle color tones. Furthermore, when the base color resin and the coloring resin are layered and gel-coated, and the coloring resin is rubbed in, the coloring area is finely formed to correspond to the wood grain-like unevenness, and a texture similar to layered wood grain is produced. Furthermore, if the base color resin is gel coated again after the additive color gel coat resin is rubbed in, the thickness of the gel coat layer is made uniform, and the hue of the additive color area is further deepened.

〔Example〕

Hereinafter, a method for manufacturing the FRP pseudo-wood board 2 according to the present invention will be specifically described with reference to the drawings.

The FRP material of the present invention has a gel coat layer 2 formed in an uneven shape imitating wood grain on the surface of a reinforcing layer 1 in which reinforcing materials such as glass fibers are laminated with adhesive resin, and this gel coat layer 2 covers most of the surface. It consists of a basic color gamut 3 and an additive color gamut 4 scattered in correspondence with the uneven wood grain pattern. Base color gamut 3 is similar to the basic colors of real wood, such as reddish-brown and blackish-brown. Also, just like in real wood, additive color areas 4 such as red, brown, black, and green are scattered in the base color area 3 corresponding to the unevenness of the wood grain, and the additive color areas 4 are also interspersed with the base color area 3. Color gamut 4 is mixed in a complicated manner, resulting in subtle changes in color tone. Furthermore, there is a base color gamut 3 on the inner side of the additive color gamut 4, increasing the color depth.

As mentioned above, the FRP material of the present invention has a gel coat layer 2 formed on the surface of the reinforcing layer 1, which imitates wood grain in three dimensions and colors, and is so refined that it is indistinguishable from the real thing in appearance and feel. It is. If you use this FRP material as a decorative board for table tops and other furniture,
Combined with the toughness that is an essential feature of RP materials, it becomes a durable and elegant product. Furthermore, if the FRP material of the present invention is formed from a heat-resistant resin and a reinforcing material and used as an exterior wall material for a house, there is no fear of decay, excellent fire resistance, and an elegant appearance.

In the above embodiment, the gel coat layer 2 with a wood grain pattern is formed only on one side of the reinforcing layer 1, but as shown in FIG. FRP pseudo-wood board material 2, which has FRP products bonded together with adhesive 6 and has a wood-grain gel coat layer 2 on both sides of a reinforcing layer 1;
It's okay.

Next, the method of manufacturing the FRP pseudo-wood board 2 according to the present invention will be explained with reference to FIG. 3.

(A) In this method, the wooden mold 7 is formed using a material with clearly raised wood grains, such as china veneer.

(B) Next, the surface of this wooden pattern 7 is sufficiently polished with wax, a release agent is applied to form a release layer 9, and then a gel coat is applied. Here, care should be taken not to smooth out the unevenness of the wood grain when waxing and applying a release agent.

(C) After the FRP type gel coat layer 10 is cured, a reinforcing layer 11 having a desired thickness is formed by defoaming while stacking sheet reinforcing materials such as glass fibers with adhesive synthetic resin.

(D) After the resins of the gel coat layer 10 and the reinforcing layer 11 are sufficiently cured, the wooden mold 7 is removed. In this way FR
A P-type 12 is formed.

(E) Next, the surface of this FRP mold 12 is brushed with penetrating wax and a mold release agent is applied to form a mold release layer 14. At this time, as in the case of the wooden mold 7 described above, the wood grain Make sure that the unevenness on the surface of the transferred FRP mold 12 is not dulled.

(F) Then, a gel coat resin of a base color such as reddish brown or blackish brown is sprayed onto the uneven surface to form a base color gel coat layer 15.

(G) After that, before the base color gel coat layer 15 is solidified, a colored gel coat resin of red, blue, yellow, green, black, etc. is rubbed into the desired location with a rag. Then FRP7!1.12
Since the surface is uneven, the base color resin is wiped off on each irregularity and the coloring resin is replaced, and the base color gel coat layer 15 becomes the base color area 3 made of the base color resin.
The gel coat layer 2 is formed by dispersing a coloring area 4 made of a coloring resin and corresponding to the wood grain-like irregularities. Here, since the base color resin and the additive color resin are appropriately kneaded, the base color gamut 3
The boundary between gamut 4 and additive color gamut 4 is clear in some places, and
In other areas, it is blurred and becomes more similar to the actual wood grain color. Note that the number of colors and the location where the colored resin is rubbed are arbitrary. Furthermore, regarding the formation of this additive color area 4, the additive color gel coat resin may be sprayed over the entire surface before the base color gel coat layer 15 solidifies, and then rubbed with a cloth. Since the resin is uniformly distributed, by rubbing it with a cloth, the coloring resin is finely rubbed into the base color gel coat layer 15 corresponding to the grain-like unevenness, making the coloration area 4 more similar to wood grain. It can be formed and its operation is simple.

(H) Furthermore, the base color gel coat resin is applied again. By re-gel-coating the base color resin, the thickness of the gel-coat layer 2 (usually about 0.5 mm) is made uniform, so that it can sufficiently play the role of a protective film for the reinforcing layer described later, and also forms the gel-coat layer 2. The colors in base color gamut 3 and additive color gamut 4 =, '-+ are deepened to make them look more like real wood grain.

(+) Thereafter, once the gel coat layer 2 is sufficiently cured, a reinforcing material such as glass fiber is laminated using an adhesive resin to form the reinforcing layer 1. In this lamination step, it is necessary to thoroughly degas the reinforcement using a motsu roller so that no air bubbles remain in the gaps between the reinforcing materials.

(J) Then, after waiting for the adhesive resin to harden, the FRP mold 12
The FRP product 5 is taken out and dirt on the surface is removed.

In the method of the present invention that goes through each of the above steps, the wooden mold 7 is formed from a material with three-dimensionally raised wood grains, and the wooden mold 7 and the FR
Since the uneven surface of the P mold 12 is sufficiently waxed and coated with a release agent, the unevenness of the wood grain is transferred as is from the wooden mold 7 to the FRP mold 12, and from the FRP mold 12 to the FRP product 5. . In addition, when forming the gel coat layer 2 of the FRP product 5, if the base color resin is gel coated on the uneven surface of the FRP mold 12, and then the colored resin is rubbed in, the uneven surface of the FRP mold 12 to which the wood grain has been transferred will be coated. Correspondingly, the base color resin is partially wiped off, and at the same time, the coloring resin is rubbed into that area, and as a result, the coloring area 4 is dispersed and formed in the base color area 3, corresponding to the unevenness that imitates the wood grain. be done. Furthermore, in the above-mentioned process of wiping off the base color resin and rubbing in the coloring resin, the base color resin and the coloring resin are mixed appropriately, resulting in a continuous discoloration area where the color tone changes subtly. The layers give the appearance of real wood.

〔Effect of the invention〕

The FRP pseudo-wood board material 2 according to the present invention has a gel coat layer formed in an uneven shape imitating wood grain on its surface as described above, and this gel coat layer has a base color range imitating the basic color of the wood surface and its base color. It consists of areas of added color scattered throughout the area corresponding to the unevenness of the wood [ ], and is so precise that it is indistinguishable from a real board with three-dimensional wood grains, both in appearance and feel. Therefore, if the plate material of the present invention is used as a decorative material for table tops, furniture, or as an exterior wall material, it will not be possible to use the board material of the present invention as a decorative material for table tops, furniture, or as an exterior wall material.
It is possible to form a durable article with a high added value and an attractive three-dimensional wood grain pattern. Furthermore, when used as a construction material, if the board of the present invention is made of resin and reinforcing material with excellent heat resistance, it will not only have an elegant appearance and durability, but also have excellent weather resistance and fire resistance. .

In addition, the manufacturing method of the FRP pseudo-wood board 2 according to the present invention includes forming a wooden mold from a board with three-dimensionally raised wood grains, and also sufficiently waxing the surfaces of the wooden mold and the FRP mold and applying a mold release agent. Therefore, the fine irregularities of the wood grain on the surface of the wooden mold are transferred intact from the wooden mold to the FRP mold, and from the FRP mold to the product, and there is almost no wear and tear on the wooden mold or FRP mold. It is also easy to demold. Furthermore, in the process of forming a product from an FRP mold, after gel coating the base color resin and before assimilating the base color resin, when rubbing the additive color gel coat resin, the three-dimensional wood grain of the wooden mold is transferred to the surface of the FRP mold. Because of the unevenness that has been removed, the colored resin is dispersed and rubbed into each unevenness, and shading is created on each unevenness due to the correspondence between the base color area made of the base color resin and the added color area made of the added color resin. It is possible to form a color-distinguished wood grain pattern on uneven surfaces. Furthermore, when the coloring resin is rubbed in, it is appropriately kneaded with the base color resin, so the color changes continuously from the base color area to the coloring area, making the layer look more like the real thing. In addition, if the base color resin and the additive color resin are gel-coated and then this color resin is rubbed into the base color resin, the color area or the wood grain-like unevenness will be finely embossed, making it even more beautiful. It can be formed to look like wood grain. As described above, in the method of the present invention, the unevenness of the wood grain pattern of the wooden mold can be easily transferred to the product by sufficient wax treatment and the application of a mold release agent. Precise coloring that corresponds to the unevenness of the wood grain pattern can be easily achieved by coating the layer twice with the base color resin and the additive color resin and rubbing it in.
