Description

[Detailed Description of the Invention] The present invention relates to a decorative board in which flocking is applied to the surface of a substrate having an uneven surface.

(Prior Art and Purpose and Structure of the Present Invention) In general, a process called flock printing is performed in which short fibers are flocked onto the surface of a flat material such as woven fabric or paper as a base material.

As an application of flock printing, a decorative paint layer is formed on the surface of a soft fiberboard, and short fibers are electrostatically flocked on the surface of the decorative paint layer in a partial pattern to create a sound-absorbing decorative ceiling board (Public Law Publication No. 46-30348). is provided.

Although the decorative surface has an improved design compared to the patterned pattern of short fibers in conventional flock printing, it has a decorative paint layer and short fibers flocked in a pattern.
or a design based on changes in each color tone,
It lacked a three-dimensional effect and was unsatisfactory.

Furthermore, as in Japanese Utility Model Application Publication No. 56-79328, a flocked foam has been proposed in which long and short piles that soften and melt are flocked onto a soft foam, and then embossed to create an uneven pattern with different shading in the concave and convex areas. .

However, such a proposal cannot be applied to a substrate made of plywood, fiberboard, etc. that has been embossed in advance. This is because, when attempting to implant hair into the recess, the direction of the raised hair becomes random, making the inside of the recess appear as if the hair is a starling, and the flocked layer conversely deteriorates the design.

The present invention aims to solve these problems of conventional decorative laminates. That is, in the decorative board of the present invention, the surface of the substrate 1 is textured,
The aim is to provide a cosmetic surface with a three-dimensional effect by implanting hair.

(Explanation of an embodiment) The present invention is characterized in that the surface of the plate-shaped substrate 1 is textured, short fibers are flocked on the convex portions 2 of the surface, and the inside of the concave portions 3 is colored and painted. Concerning decorative boards intended for improvement.

The manufacturing method of the decorative board of the present invention will be explained below.

Grooves 3 and arbitrary pattern recesses 3 are formed on the surface of the plate-like substrate 1 by embossing, cutting, etc.

The plate-like substrate 1 may be any inorganic or organic board such as plywood, fiberboard, cement board, silica board, PC board, or a mixed or composite plate of inorganic and organic materials.

Further, the plate-shaped substrate may be subjected to actual processing such as interlocking processing or actual processing on two or four sides of the butt ends, and the shape and material thereof are not particularly limited.

Further, if necessary, a surface treatment is performed on the surface of the plate-like substrate.

Surface treatment is a process that hides or strengthens the surface of a plate-like substrate, smooths the surface, and improves the adhesion of surface coatings, adhesives, etc., and also includes surface treatment, sealer coating, undercoat coating, Methods such as sanding are used.

A colored coating 4 is applied to the entire surface including the concave portions 3 on the surface subjected to the base treatment, or a colored coating is applied only to the convex portions 3 of the surface, and a pattern is printed.

Patterns can be printed using gravure, graphoff, flat printing using an offset printing machine, gravure, etc.
By embossed printing using a screen printer, etc.

The adhesive c is applied over the entire surface or in a pattern onto the convex portions 2 on the surface of the plate-shaped substrate 1 using a roll coater, a spreader, screen printing, or the like.

Adhesives include vinyl acetate, polyacrylic ester, vinyl acetate acrylic copolymer, vinyl acetate vinyl chloride copolymer,
EVA, acrylic vinyl chloride copolymer, synthetic rubber (MBR,
Use organic or inorganic adhesives such as NBR, SBR), polyurethane, and water glass, and if necessary, use pigments for optional coloring.

The plate substrate 1 coated with adhesive c is inserted into an electrostatic flocking device.

A layer of short fibers p is formed by flocking short fibers p onto a layer of adhesive c applied on the convex portions 2 on the surface by electrostatic flocking.

Next, the flocked short fibers P are pre-dried using a drying device to temporarily fix the flocked short fibers P, and the excess short fibers P are collected using a vacuum device.

In the electrostatic flocking method, a plate-like substrate is transported with its decorative surface facing upward, a ground electrode is placed on the substrate side, a high voltage electrode is provided above it, and the short fibers are fed into an electric field from above and directed downward. The down method method involves transporting a plate-like substrate with its decorative surface facing downward, and the up method method uses a grounded electrode on the substrate side and a high-voltage electrode below the short fibers to fly the short fibers upward. Either one is fine.

Short fibers include human silk, synthetic fibers (nylon,
Can be transparent or opaque, using fabric such as cashmilon, vinylon, cordieran, polyester, acrylic, etc.), hemp, wool, or glass fiber that has been electrodeposited to improve flight in an electric field. .

Although it may be a twisted yarn, it is preferable to use a straight raw yarn in which the molten raw material liquid is extruded from a nozzle during the spinning process.

Next, the plate-shaped body on which short fibers have been flocked is inserted into a drying device, the adhesive c is solidified, and the short fibers p are spun.

If necessary, apply a transparent top coat to the entire surface using a flow coater, spray, etc., dry in a drying device, and apply a top coat.

Plate-shaped substrate 1 with unevenness processed in this way
A decorative board was obtained in which the concave portions 3 on the surface were coated with optional colored coating 4, and short fibers P were flocked onto the convex portions 2 on the surface.

(Effects of the present invention) The decorative board has improved design as the colored coating 4 on the concave portions 3 on the surface and the short fiber flocked portions on the convex portions 2 are mixed together.
In addition, the unevenness of the surface gives it a rich three-dimensional feel and a luxurious feel, further improving the design.

That is, the present invention is based on the prior art disclosed in 1983.
Based on the new idea of using colored paint instead of flocking inside the recesses as in No. 79328, an appropriate decorative pattern is expressed on a board that has been embossed in advance.
