BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for coloring a grooved decorative material.

[0002]

2. Description of the Related Art There is a grooved decorative material whose surface is grooved for flooring and wall materials. This kind of grooved decorative material is useful as a material that has a three-dimensional appearance and creates a neat design because the surface is divided into blocks by the groove processing. The grooved decorative material is formed by adhering a decorative veneer on a plywood which is a base plate, grooving the surface of the decorative veneer, and clear-coating the entire surface with transparent paint.

[0003]

However, the grooved decorative material formed as described above has the following problems in design.

That is, in order to increase the three-dimensional effect in the grooved decorative material, the groove is formed deeply. In that case, the cut extends to the upper layer of the lower plywood,
Since the color of different plywood is exposed in that part,
The color of the groove was not unified, and the design was lost. In addition, the dark color of the plywood that stands out too much in the groove also impaired the design.

Therefore, in order to solve such a problem,
It is conceivable to use a thick decorative veneer so as not to cut deep into the plywood, but in that case the cost will be very high. Therefore, in the past, a light-colored material such as Vatican material (mackerel) was selected and used as the plywood material, but it is difficult to secure the plywood material. It was

Although it is conceivable to color the grooves to be uniform, it is difficult to color only the thin grooves with high precision, which is difficult in industrial production.

The present invention has been made by paying attention to the above points, and it is an object of the present invention to provide a grooved decorative material excellent in designability by using an inexpensive general-purpose plywood as a base plate. To aim.

[0008]

According to a first aspect of the present invention, a makeup veneer is made by adhering a decorative veneer on a base plate and grooving the surface of the veneer to the base plate. Apply a transparent paint to the surface of the veneer, apply a colorant over the groove and the transparent paint surface of the decorative material, and scrape and remove the colorant on the transparent paint surface to color the groove. did.

The above-mentioned transparent paint is only required to be transparent to the extent that the lower decorative veneer can be seen, and may contain a coloring agent.

According to a second aspect of the present invention, in addition, in the first aspect of the invention, the transparent paint has a low permeability.

According to the invention of claim 3, in the invention of claim 2, the transparent paint is resin-rich.

According to a fourth aspect of the present invention, in the first, second and third aspects, the colorant is rich in extender pigment.

[0013]

According to the invention of claim 1, the colorant layer on the transparent paint layer of the decorative material is scraped off, the transparent paint layer remains on the decorative veneer, and the colorant remains only in the groove. The inside of the groove is colored.

According to the invention of claim 2, in addition to the invention of claim 1, the penetration of the colorant into the transparent paint is small, the colorant layer is surely held on the transparent paint layer, and the scraping thereof is possible. It is done efficiently.

According to the invention of claim 3, in the invention of claim 2, the penetrability of the transparent paint is reduced without adding other additives.

According to the invention of claim 4, claim 1, 2,
In the invention of 3, the colorant ensures that the inner surface of the groove is concealed.

[0017]

The coating method of the present invention will be described below with reference to the drawings.

(1) Fabric Polishing As the decorative material 1, as shown in FIG. 1, a decorative veneer 3 having a thickness of 0.3 mm or less is attached to the surface of a plywood 2 as a base plate, and the decorative veneer 3 is A V-groove 5 which is formed on the surface and extends to the upper layer of the plywood 2 is used. As the above-mentioned plywood 2, general-purpose inexpensive kacha and red material are used, and as the decorative veneer 3, for example, Mizurana, oak, and cherry wood are used.

Then, the entire surface of the decorative material 1 is polished with a paper having a small grain size (roughness # 320 to # 400) to make it smooth.

(2) Disposal coating On the surface of the decorative veneer 3 of the decorative material 1 having a smooth surface, as shown in FIG. 2, a colored transparent paint 7 is applied by a roll coater.
Apply.

As the colored transparent paint 7, a lacquer diluted with thinner and mixed with a slight colorant is used. The degree of dilution of the above lacquer with thinner is such that the viscosity of the colored transparent paint 7 is 20 to 25 seconds / Iwata N.
The coloring transparent coating 7 is rich in resin by making the degree of dilution as high as K-2 and having low permeability.

The colored transparent paint 7 remains on the product, and the oak material exhibits a color close to that of a candy color when sunburned to enhance the design of the decorative material 1. Further, the designability can be further improved by mixing a slight amount of the colorant.

(3) Colored Wiping After the colored transparent paint 7 on the surface of the decorative veneer 3 is dried, as shown in FIG. 3, the colorant 8 is applied to the entire surface of the decorative material 1 with a waste cloth attached to the rotating body. .

As the coloring agent 8, for example, a coloring pigment 42% and an extender pigment 58% diluted with urethane or thinner is used. Color pigment is 30-70
% And extender pigments are used in the range of 70 to 30%.

When coloring, the colored transparent paint 7 located in the lower layer
Has a low permeability, the colorant 8 does not penetrate into the colored transparent paint 7 layer, whereby the colorant 8 layer is reliably held on the colored transparent paint 7 layer. Further, the coloring agent 8 has a higher viscosity due to the higher mixing ratio of the extender pigment, and surely hides the inner surface of the groove 5 without being absorbed by the coating surface.

(4) Scraping Then, the colorant 8 on the layer 7 of the colored transparent paint is scraped off with a reverse coater.

In this state, as shown in FIG. 4, the decorative material 1 is in a state in which the coloring agent 8 remains only in the groove 5 and the inside of the groove 8 is colored. Colored transparent paint 7 on the decorative veneer 3
Is left. At the time of this scraping, the colorant 8 layer is held on the colored transparent paint 7 without penetrating the colored transparent paint 7, so that only the colorant 8 can be easily scraped off.

The surface of the cosmetic material 1 thus obtained is further washed with a wash roll. As the roller used here, a rubber roller having a hardness of 40 to 50 ° is used. After drying, a sanding sealer is used for undercoating, and then overcoating is applied for clear coating to complete the coating, and the product is obtained.

In the above embodiment, the colored transparent paint 7
The resin is rich in the resin to reduce its permeability, but other methods may be used.

Although the coloring agent 8 is colored on the entire surface of the decorative material 1 in the above embodiment, it may be colored only on the surface of the groove 5 and the colored transparent coating 7 in the vicinity thereof.

[0031]

As described above, according to the first aspect of the invention, the colorant layer on the transparent paint layer of the decorative material is scraped off so that the transparent paint layer remains on the decorative veneer and the groove is formed. Since the colorant remains only in the inside and the inside of the groove is colored, by this,
Coloring inside the groove can be done easily and accurately, and as a result, it is possible to use abundant and inexpensive plywood etc. which will be the base plate without being affected by its color, as a result,
It is possible to provide a grooved decorative material that is inexpensive and has an excellent design.

Further, since the transparent paint layer remains on the decorative veneer, a decorative material having a higher design property can be obtained.

According to the invention of claim 2, in the invention of claim 1, further, since the penetration of the colorant into the transparent paint is small and the colorant layer is reliably held on the transparent paint layer,
The scraping is performed efficiently and the workability is excellent.

According to the invention of claim 3, in addition to the invention of claim 2, the transparent coating has a reduced permeability without addition of other additives, so that the transparent coating can be easily obtained. .

According to the invention of claim 4, claims 1, 2,
