Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a decorative board having a sheet-shaped material 2 adhered thereto and a method for producing the same.

[Prior art and its problems]

For example, the following proposals have been made for a decorative board coated with wood fibers.

B. As shown in Japanese Examined Patent Publication No. 40-14990, an uneven pattern is formed on the surface, a transparent paint is applied over this pattern surface, the pigment in the paint is allowed to settle in the concave part of the pattern, and the convex part of the pattern is It is known that only a transparent layer can be formed.

In this proposal, the ground color of the article is expressed in the convex part of the pattern through the transparent layer, and the pigment in the paint is settled and colored in the concave part, but it is monochromatic in color and monotonous in design. There is a drawback.

Also, as in Japanese Utility Model Publication No. 50-104475 filed by the present applicant, a sealer coating layer is layered on the convex outer surface of a substrate made of wood fiber, and an opaque coating film is layered on the surface and the concave outer surface. A coating board having a uniform color tone and an uneven pattern formed by layering the coating thickness of the semitransparent coating layer on the opaque coating layer on the concave surface to be thicker than the convex surface is also proposed. ing.

This proposal forms a sealer coating layer on a convex outer surface having a low specific gravity, prevents the absorption of the colored coating material applied to the surface, and thus provides a uniform colored coating layer regardless of the surface density of the uneven outer surface. By applying the semitransparent coating layer after forming, the semitransparent coating layer is layered so that the convex outer surface portion is thin and the concave outer surface portion is thick. Therefore, on the concave surface, the color tone of the opaque coating layer is emphasized by passing through a thin semitransparent coating layer, and on the concave surface, the color tone of the opaque coating layer is almost hidden by the semitransparent coating layer. The color tone is emphasized.

Further, even in the intermediate portion from the convex surface to the concave surface, the translucent coating film layer is thickened according to the depth of the concave portion, so that the change in the color tone of the convex surface and the concave surface is the same. There are no faults due to the difference in shade, which causes a natural color change.

However, although improved in terms of design, the production line must be complicated because two layers, a colored coating layer and a semi-transparent layer, must be configured, and the difference in shade of the same paint makes it difficult to change the color tone. I have left.

[Means to solve the problem and its action]

The present invention has the following configuration to solve the above problems.

That is, in the decorative board according to the present invention, the sheet-like material 2 on which the coating material is prevented from being sucked is attached in a pattern on the surface of the substrate, and the specific gravity is applied to the portion 3 where the coating material is prevented from being sucked. Pigmented coating 4a with a high particle size and large particles settled, and a pigment 4b with a low specific gravity and a small particle layered on top of it, a convex colored coating layer A is formed on the other part 3a which has not been subjected to a suction prevention treatment. A decorative board and its production in which a pigmented colored coating layer B having a low specific gravity and small particles 4b is impregnated and impregnated into a sheet, and a pigmented layer 4a having a high specific gravity and large particles is formed on the sheet. Is the way.

According to the present invention, by adopting the above-mentioned constitution, the colored coating film layer convex-colored coating film layer A, which has different colors in the coating material suction prevention treatment portion 3 and the non-suction prevention treatment portion 3a such as the sealer of the sheet-like material 2, B is obtained in a single painting process. That is, a coating layer having a high design property can be obtained by a simple process. Examples of the present invention will be described below.

[Explanation of Examples]

 1 to 4 show an embodiment of the present invention.

1 to 4, the substrate 1 may be any one of an organic plate-shaped body such as a plywood, a fiber board, a cement plate, and a wood chip cement plate, an inorganic plate-shaped body, an organic-inorganic mixed plate-shaped body.

A sheet-like material 2 is attached to the base material 1 as shown in FIG.

At this time, the sheet-like material is attached using a laminator device, a press device, or the like after applying an adhesive to the surface of the substrate or the surface of the sheet-like material or each of them. Examples of the adhesive used include vinyl acetate, ethyl acetate, urea resin adhesive and the like.

The sheet-like material 2 may be a material that can penetrate the coating material, and is not particularly limited to synthetic resin, thin paper, cloth-like material, or the like.

Next, a sealer is applied in a pattern on the surface of the sheet-like material 2 by using a coating device as a paint suction preventing treatment to form a sealer coating layer 3.

Reference numeral 3a is a non-sealer portion which is not subjected to the sealer treatment.

Next, as shown in FIG. 2, a coating device for applying a colored paint 4 in which a pigment 4a having a high specific gravity and a large particle and a pigment 4b having a low specific gravity and a small particle are arbitrarily mixed on the entire surface on which a sealer is applied in a pattern To be applied almost uniformly.

When left standing for a while, the colored coating material 4 has a sealer layer formed on the sealer coating layer portion 3, so that the colored coating material 4 is not sucked into the base material 1 and is convex as shown in FIG. Form layer A.

In the convex colored coating layer A, the pigment 4a having high specific gravity and large particles and the pigment 4b having small specific gravity and small particles are mixed in the colored coating material 4, so that the pigment 4a having high specific gravity and large particles sediments, On the contrary, the pigment 4b having a low specific gravity and small particles is constituted so as to form a layer on the upper portion thereof.

Therefore, the convex colored coating film layer A on the sealer coating film layer portion 3 is expressed with a thick coating film, a low specific gravity and a small color tone of the pigment 4b having small particles.

By changing the addition amount of the pigment 4b having a low specific gravity and small particles, for example, by decreasing it, the color tone of the upper layer containing the pigment 4b is transmitted, and the specific gravity settled at the bottom of the convex colored coating layer A is The color tone of the pigment 4a, which is high and has large particles, is influenced and appears, and a subtle color change is obtained.

Since the sealant coating film is not formed on the non-sealer portion 3a, the colored coating material 4 is partially sucked into the sheet-like material 2 to form the concave colored coating film layer B.

The concave colored coating layer B is a mixture of the pigment 4a having a high specific gravity and large particles and the pigment 4b having a low specific gravity and small particles in the colored coating material 4, so that the coating material 4 is sucked into the base material 1. Due to the flow, the pigment 4b having a small specific gravity and small particles is sucked into the substrate 1 together with the coating material 4, and the pigment 4a having a large specific gravity and large particles is left on the non-sealer portion 3a to form a layer. Is configured as follows.

Therefore, the coating layer of the concave colored coating layer B on the non-sealer portion 3a is slightly thinned, and the color tone of the pigment 4a having a high specific gravity and large particles is expressed deeply.

By changing the addition amount of the pigment 4b having low specific gravity and small particles or the pigment 4a having high specific gravity and large particles, the pigment 4b having low specific gravity and small particles 4b left in the concave colored coating layer B on the non-sealer portion 3a. Of the pigment 4a, 4b
The color tone is influenced and appears, and a subtle color change is obtained.
This color change can also be obtained by changing the addition amount of the pigment 4a having high specific gravity and large particles. If necessary, a topcoat may be applied to the entire surface of the sheet-like material 2 on which the convex colored coating layer A and the concave colored coating layer B are formed.

By changing the colors of the pigment 4a having a high specific gravity and large particles and the pigment 4b having a low specific gravity and small particles, the colors of the sealer coating layer portion 3 and the non-sealer portion 3a can be changed, which improves the design. Be useful.

In the above examples, the application of a sealer was described as an example of the paint suction prevention treatment, but in addition to this, sealing, resin impregnation, paint, etc. may be used to perform paint suction prevention treatment. it can.

[Advantages of the Invention] Using a colored paint in which a pigment having a low specific gravity and a small particle is mixed as a pigment having a high specific gravity and large particles, a convex portion and a concave portion of a surface uneven pattern are formed due to a difference in suction of the coating material on the decorative sheet material 2. The color change with the pattern portion can be obtained, and such color change can be performed by one color coating. Further, the color change can be easily made subtly by changing the addition amount of each pigment.

Since the colored paint is applied to the sheet-like material 2, it is not necessary to use an expensive base material, and a makeup with a color change can be provided at low cost.
