Description

[Detailed description of the invention] This invention relates to a decorative board with a three-dimensional pattern, and its purpose is to prevent the effects of small irregularities such as channel grooves and raised chips on the surface of the board from appearing on the surface of the decorative board. The purpose of the present invention is to provide an appearance of a decorative board that is both visually appealing and rich in three-dimensionality.

Traditionally, when a substrate is made of plywood or vertic board made from a hardwood veneer such as lauan wood, and the surface is decorated by applying paint or pasting a decorative board or decorative film, etc., the substrate The effects of small irregularities such as vessel grooves and raised chips often appear on the surface of the decorative laminate as discoloration or dark spots, which also causes a decrease in the appearance of the surface of the decorative laminate.

Therefore, in the past, attempts were made to prevent the appearance of discoloration and dark spots by applying filler paint or attaching thick decorative boards or films.

However, methods such as base treatment and thickening the decorative sheet naturally led to an increase in the number of manufacturing steps and an increase in raw material costs, resulting in an increase in product prices.

This idea solves the above problems.

That is, in this invention, a thin leaf pattern printing paper 3 is attached to the surface of a substrate 1 having small irregularities via an adhesive 2, and then a transparent paint 5 is applied to the surface, and after drying to a semi-cured state, the surface is coated. After forming recesses 6 with a texture on the surface, using transparent resin ink to form a transparent raised pattern 7 that matches a part of the pattern 4 on the printing paper, the entire surface is further coated with transparent paint. The three-dimensional patterned decorative board is characterized by a three-dimensional patterned decorative board, and its most distinctive feature is that it forms recesses in the texture of the entire transparent paint layer applied to the top surface of the thin leaf pattern printed paper adhered to the substrate surface. The purpose is to make small irregularities such as channel grooves and raised edges of chips less noticeable.

Hereinafter, this invention will be explained in detail with reference to drawings showing embodiments of the invention.
Reference numeral 1 is a substrate having small irregularities, such as a commonly used substrate such as plywood with concave pipe grooves, vertic board with raised chips, or asbestos board with uneven papermaking.

2 indicates an adhesive layer, and 3 indicates a thin printing paper.

Adhesive 2 is a commonly used vinyl acetate resin emulsion type,
Urea resins, urethane resins, phenol resins, melamine resins, etc., and emulsion type adhesives are particularly preferred.

The thin-fed printing paper 3 has a desired pattern 4 printed on thin paper having a weight of about 15 to 609/lri by a commonly used printing method such as gravure printing, offset printing, and flexible printing.

Note that the thin printed paper 3 is preferably attached so as to follow the small irregularities of the substrate 1 as much as possible.

Reference numeral 4 denotes a pattern printed on the thin-fed printing paper 3, which is an arbitrary pattern such as a commonly used wood grain pattern, a flower pattern, or a tile pattern.

5 is a transparent paint layer applied to the surface of thin printing paper 3;
Allow the paint to dry until it is fully cured.

The amount of coating is about 50 to 100 f/d, and the resin used is mainly a commonly used urethane resin, amino alkyd resin, acrylic resin, vinyl resin, lacquer, etc.

6 is a recess in the texture formed on the surface of the transparent paint layer 5;
It is best to shape it by overlapping wire mesh or pressing it with an embossing roll.

The depth and width of the recesses 6 in the cloth are not particularly limited, but the depth is 0.
．． In order of 1 to 1.0, the eye width is preferably about 1 to 5 TIrII&.

7 shows a transparent raised pattern that is in sync with a part of the pattern 4 of the printing paper 3.

The transparent raised pattern 7 is formed by printing a high solid content ink such as transparent acrylic resin, epoxy resin, or urethane resin so as to be thickly raised using a method such as screen printing.

The height of the bulge is preferably about 100 to 300 microns because it gives an excellent three-dimensional effect.

Note that the transparent ink may be colored with a dye or the like, and may be colored and transparent.

8 is a top-coated transparent paint that is applied to protect the surface of the decorative board and improve its aesthetic appearance.

Commonly used amino alkyd resins, urethane resins, acrylic resins, etc. are used as paints, and the coating amount is 80%.
~100 f/rd.

As described above, in the decorative board of this invention, the effects of small irregularities such as vessel grooves and raised chips on the board surface are eliminated by the textured concavities, giving the decorative board a soft, textured appearance. At the same time, the areas where the textured recesses are exposed on the decorative surface reduce the gloss due to diffuse reflection of light, and the lens effect of the transparent raised pattern that is synchronized with a part of the printed pattern makes the printed pattern stand out. In reality, the transparent raised pattern forms a concavo-convex pattern, making it possible to provide a decorative board with a three-dimensional pattern that is extremely three-dimensional and luxurious in appearance.

Next, examples will be described.

EXAMPLE A lauan plywood board having a thickness of 1277 Il11 was used as a substrate. A vinyl acetate resin adhesive was applied to the surface of the board at 80 to 100 g/d, and a floral print paper weighing 3597 rd was overlaid and bonded under heat and pressure.

Then, 50 to 60 g/d of a urethane resin-based transparent paint was applied to the entire surface of the printing paper, and the coating was dried at 70 to 80'C.

The surface of the coating film was then compressed with an embossing roll having textured irregularities to form textured recesses with a depth of approximately 0.3 to 0.5 degrees.

Next, a screen printing plate was stacked so as to match the pattern of the printing paper, and printing was carried out to a thickness of 250 μm using an acrylic resin emulsion type transparent ink.

Next, after drying it at 70 to 80'C for 3 hours, apply 8097rd of transparent urethane resin paint to the entire surface and dry it.
I got the three-dimensional pattern decorative board I was looking for.
