Description

Description: TECHNICAL FIELD The present invention relates to a method for producing a decorative inlaid decorative veneer that can be used as a top plate of a housing or kotatsu.

[Prior Art and Its Problems] Conventionally, inlays have been widely used as high-class crafts, but since they are very expensive, they are generally used for small items such as heavy boxes, and top plates for housing and kotatsu. It was economically difficult to widely use it for general household products.

[Means for Solving Problems] The present inventors have arrived at the present invention as a result of intensive studies in view of the above points.

 An embodiment of the present invention will be described below with reference to the drawings.

First, the colored layer 2 having a desired inlaid basic tone color is formed on the surface of the plate-shaped substrate 1. As a method for forming the same, after applying a sealer to the plate-shaped substrate 1, a colored paint is applied by a spray or a roll coater, or a colored sheet or a decorative sheet with a patterned pattern is attached.

Next, the convex pattern layer 3 having an appropriate shape and excellent in transparency is formed. The convex pattern layer is formed by screen printing, and the film thickness thereof is preferably 50 to 150 μm, and the higher the transparency, the better, but the light transmittance of 50% or more is acceptable for use. The ink used for screen printing is an ultraviolet curable ink, which has a short curing time and is convenient for work.

Next, if necessary, the surface of the convex pattern layer is polished to make it smooth, and then colored paint layers 4 and 4'having excellent polishing properties are formed by a spray or a roll coater. After drying, the convex pattern layer is exposed and polished until the surface becomes smooth. After that, a transparent top coat 5 is applied to the entire surface.

In order to improve the abradability of the colored paint layers 4 and 4 ', 1 to 3% by weight of polyethylene fine powder may be mixed in the paint.

Through the above steps, the basic color of the inlay is revealed through the transparent convex pattern layer, and the colored paint layer 4 around the convex pattern layer 3 which is revealed by polishing serves as an edge of the convex pattern layer, and the inside of the colored paint layer 4 '. A decorative board having an inlay-like appearance, in which the convex pattern layer 3 is fitted in, can be obtained. When three or more coating layers are applied, double or more edging is applied.

[Examples] The present invention will be specifically described below with reference to examples.

Example 1 A sealer was applied to the surface of a thick wood fiber board, dried, and then ground, and a urethane coating containing 10% by weight of a pearl pigment as a base color of inlay was applied by a roll coater to form a pearl colored layer. . Next, a convex pattern layer in the shape of a shell was formed by screen printing in a state of being scattered with a UV-curable acrylate screen ink having a transparency of 80%. The thickness of the convex pattern layer was about 100 μm.

Next, a urethane-based white paint containing 1% by weight of polyethylene fine powder is applied by spraying, and then a urethane-based black paint containing 1% by weight of polyethylene fine powder is applied in the same manner. Layers were formed. After the paint layer is thoroughly dried, the wide belt sander (# 240
The surface of the convex pattern layer was exposed with a paper) and polished until the surface became smooth.

Next, a transparent acrylic urethane topcoat was applied to the entire surface.

A pearl-colored convex pattern layer having a white edging was scattered in the black paint layer, and a decorative inlaid decorative plate as if a piece of shell was fitted was obtained.

Example 2 A 40 g / mm ² resin-impregnated paper having a grain pattern printed on the surface of a lauan plywood was attached via an adhesive. Next, after forming a convex layer in the shape of natural stone, 2% by weight of fine polyethylene powder
The mixed gray and white urethane paints were sequentially applied to form two colored paint layers, and a natural stone having a gray edging was inserted into the white paint layer in the same manner as in Example 1. A veneered veneer with excellent decorativeness was obtained.

[Effects of the Invention] As described above, in the inlaid decorative board of the present invention, a convex pattern layer of an appropriate shape is formed by screen printing on the colored layer colored in the basic color of the inlay, and two or more layers are formed thereon. The colored coating layer is formed and then polished and applied with a top coat, so that it is very inexpensive and can be widely used for general furniture such as tops of dwelling machines and kotatsu.

Claims (1)

(57) [Claims] 1. A colored layer having a basic color of inlay is formed on the surface of a plate-shaped substrate, then a convex pattern layer having excellent transparency is formed by screen printing, and two colored paint layers are further formed on the entire surface. After the above-mentioned formation, a method for producing an inlaid decorative board is characterized by polishing until the convex pattern layer is exposed and applying a transparent top coat on the entire surface.
