Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plate-shaped decorative board used as a surface material for furniture, system kitchens, interior materials, etc., and a method for manufacturing the same.

[Prior art] Conventional decorative boards of this type are those with printed paper glued to the base, and a special type of decorative board with a structure of Japanese paper glued to the base is disclosed in Japanese Patent Publication No. 56-45658. It is stated in the official gazette.

[Problems to be Solved by the Invention] However, the decorative board made by adhering printed paper has the disadvantage that the color or pattern of the printed paper directly appears on the surface and lacks depth. In addition, the paper bonded with Japanese paper described in the above publication is made by repeating colored painting and sanding on the Japanese paper to improve its texture, but since it is a one-off product, it is difficult to achieve the desired color or texture, and it is difficult to obtain the desired color or texture. There are problems when there are differences between the products.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a decorative board that is rich in depth and decorativeness and that can mechanically obtain a predetermined color or pattern.

[Means for Solving the Problems] Next, the means for achieving the above object will be explained.

That is, in the first invention of the present application, a nonwoven fabric having a transparent structure is adhered to the upper surface of a base,
The decorative board is characterized in that colored coating is applied from the upper surface of the base and the upper surface of the nonwoven fabric, and a transparent or translucent resin layer is formed on the upper surface of the nonwoven fabric.

Further, the second invention of the present application is to apply a base colored coating to the upper surface of the substrate, adhere a nonwoven fabric having a transparent structure to the upper surface, apply a colored coating for nonwoven fabric to the upper surface of the nonwoven fabric, and apply a colored coating to the upper surface of the base. The present invention provides a method for producing a decorative board, characterized in that a transparent or semitransparent resin layer is formed on the upper surface of a nonwoven fabric.

Further, in the first and second inventions, a substance having light reflecting or light scattering properties such as aluminum foil or aluminum powder may be mixed into the resin layer or disposed on the upper surface of the nonwoven fabric. .

[Function] From a nonwoven fabric having a transparent structure, the surface color of the substrate can be seen through, and the density of the fibers making up the nonwoven fabric is partially different, so the decorative board according to the present invention can be seen through the resin layer on the upper surface. Although it is possible to obtain deep and diverse expressions, there are variations in the expression of product colors. However, in the present invention, since the upper surface of the substrate and the upper surface of the nonwoven fabric are colored, the variation in the surface color of the substrate or the pattern such as wood grain on the surface and the pattern of the nonwoven fabric fibers is caused by the above-mentioned coloring. The combination of the above two layers of coloring makes it possible to express even more diverse tones.

Furthermore, since a non-woven fabric is used as the decorative layer, it is easy to apply, it is difficult to see even if cuts are made, and the adhesive resin permeates into the non-woven fabric, increasing its strength. It is also possible to process different patterns by pasting them together. Note that when printed paper is used as the decorative layer, paper peeling may occur, but when the above-mentioned nonwoven fabric is used, such a problem does not occur.

[Example] Figures 1 and 2 are a longitudinal sectional view and a partially cutaway plan view of a decorative board according to a first embodiment of the present invention, which will explain the first embodiment. .

Reference numeral 1 denotes a base of the decorative board 10, which is made of natural wood, veneer, particle board, or the like. The upper surface of this base body 1 is colored (colored) by spray painting or the like, and a base coloring coating 2 is applied to determine the color base of the decorative board. 4 is a transparent adhesive 3 on the base 1 on which the base color coating 2 has been applied.
It is a non-woven fabric bonded together with long fibers of natural or synthetic fibers entwined in an irregular shape to form a thin sheet structure that can be seen through, and is colorless or has a specific color. Furthermore, this nonwoven fabric 4 is colored with a desired color (coloring) by applying a colored coating 5 for nonwoven fabric by spray painting or the like. 6 is a relatively thick intermediate resin layer made of polyester coating, and 7 is an upper resin layer for protection and polishing.

The above decorative board is manufactured by applying coloring to the upper surface of the base 1 by spraying and applying a base coloring coating 2.
A nonwoven fabric 4 is adhered thereon using an adhesive 3.
Next, the upper surface may be colored by spraying to apply the colored coating 5 for nonwoven fabric, and the intermediate coating resin layer 6 and the top coating resin layer 7 may be sequentially applied to the upper surface.

In the decorative board according to the first embodiment, the base colored coating 2 on the upper surface of the substrate 1 can be seen through the thick intermediate resin layer 6 and the nonwoven fabric 4, and a rich and varied expression can be obtained.

In addition, on the upper surface of the base 1 and the upper surface of the nonwoven fabric 4,
Since the colored coatings 2 and 5 are respectively applied, a variety of colors can be expressed, and there is no variation in the color tone of the product, and no discrepancy occurs between the sample and the product.

3 and 4 are a longitudinal sectional view and a partially cutaway plan view of a decorative board according to a second embodiment of the present invention.

The decorative board 110 according to the second embodiment has a substance 8 having light reflecting or light scattering properties disposed on the upper surface of the nonwoven fabric 4 which has been colored with a colored coating 5. is the same as in the first embodiment.

This light-reflecting or scattering material 8 is formed of glass, shell, metal foil such as aluminum, powder, or the like.

Further, the substance 8 may be provided in a recess formed by embossing the nonwoven fabric 4 as shown in FIG. 3, or may be simply sprinkled. Furthermore, it may be mixed into the intermediate coating resin layer 6.

[Effects of the Invention] As explained above, according to the present invention, it is possible to see through the resin layer and the nonwoven fabric, it is robust and easy to manufacture, and it is possible to obtain a deep and highly decorative expression. There is.

Further, according to the present invention, since the upper surface of the substrate and the upper surface of the nonwoven fabric are colored and painted, it is possible to express a variety of colors. Partial variations in the pattern are evened out, there are no problems such as discrepancies between the sample and the product, and the desired color pattern can be obtained mechanically, which increases the commercial value of this type of decorative board. It has the effect of improving
