Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a decorative board having a pattern on its surface, and in particular, having large surface irregularities,
The present invention relates to a method for efficiently manufacturing a decorative board having a different design and having different top coats.

[0002]

2. Description of the Related Art Conventionally, various decorative boards have been used for exterior and interior of houses and as furniture members, but in recent years, products having unevenness on the surface have become popular along with the tendency toward high quality and high design. It has become popular. In the case of a conventional product having a flat surface, as a method of providing a pattern on the surface, for example, a method of laminating a film on which a pattern is printed on the surface can be used, but when the surface has irregularities For this reason, there was no choice but to resort to a simple method such as painting a single color paint or sprinkling sand.

Further, depending on the place where the decorative plate is used,
A top coat is often applied for the purpose of surface protection, but in most cases, a single top coat is used, such as a gloss coat only for the gloss coat and a matte coat only for the mat coat. When applying a high-gloss gloss coat or matte coat, which is often seen in wallpaper, to these decorative plates, first apply either top coat to the entire surface, then use masking tape, etc., and then apply again. It required extremely complicated work.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a decorative plate having large irregularities on the surface thereof with concave and convex portions. Another object of the present invention is to provide a method for manufacturing a decorative plate, in which different top coats are efficiently provided.

[0005]

In order to solve this problem, the present invention uses a rubber relief printing plate in a concave portion (hereinafter, referred to as a joint portion) of a decorative plate base material having a large surface unevenness. Provided is a method for manufacturing a decorative board, which is characterized by applying a coat.

The present invention will be described in detail below. FIG. 1 shows an example of the structure of a transfer sheet used in the present invention.
The base sheet 11 has a structure in which a release varnish layer 12 and a pattern layer 13 are sequentially provided.

FIG. 2 shows an example of the transfer method of the transfer sheet. After applying the adhesive to the uneven surface of the decorative plate base material 21 by various methods, the pattern layer surface of the transfer sheet 22 shown in FIG. 1 is installed and pressed with the heat roll 23 from the surface to transfer the desired pattern. To do.

The hot roll used at this time is appropriately determined according to the intended design. That is, this is the case where a pattern to be transferred is applied to the entire surface of the decorative plate, or the transfer pattern is applied only to the convex and concave portions of a large pattern.

FIG. 3 shows an example of the structure of a decorative board obtained by the method for manufacturing a decorative board of the present invention. An embossed plate 31, an adhesive layer 32, a pattern layer 33, and a gloss coat to be decorated.
The matte coat is sequentially laminated. At this time, the order of the growth coat and the matte coat may be reversed if desired.

[Example] As a base sheet for a transfer sheet, a thickness of 50 μm
The semi-cured vinyl chloride film of No. 1 was used, and the following layers were laminated thereon by gravure printing to obtain a transfer sheet.

Peeling varnish layer: Polyvinyl butyral Picture layer: Brick-like printing ink consisting of coloring pigments (phthalocyanine blue, dianthraquinonidril red) and poly (vinyl chloride)

50 g / m ² coating of a white two-component curing urethane paint using titanium oxide as a pigment by using an air spray, using a fiber reinforced cement plate with a brick-like concavo-convex pattern as a decorative board substrate. Then, it was dried by heating in an oven at 80 ° C. for 9 minutes.

The transfer sheet was placed thereon with the pattern layer facing down, and the surface temperature was 160 ° C. Heat roll (Rubber hardness of outer layer 3
0 ℃, 3mm thick silicon rubber, inner layer rubber hardness 80 ℃
It was pressed with an EPT rubber having a wall thickness of 17 mm. The pressure was 10 kg / cm ^{2 and the} speed was 5 m / min. The decorative plate obtained after peeling the base sheet of the transfer sheet has white joints,
The brick part had been transcribed.

An acrylic silicone type gloss clear top coat was applied to this decorative plate by air spray. The coating amount was 80 g / m ² . This was dried in an oven at 120 ° C. for 15 minutes and then left at room temperature for one day.

Acrylic silicone mat clear top coat was applied to this using a rubber relief plate only on the joints. The resulting decorative board was printed with a delicate pattern printed on the bricks and further subjected to a gloss top coat, and the joints had a white adhesive layer with a mat top coat,
The design was extremely high.

[0016]

As described above, according to the present invention, it becomes possible to impart a beautiful pattern on the surface of various decorative boards having an uneven surface in synchronization with the uneven pattern. In particular, an embossed decorative board having a beautiful gloss mat pattern on the uneven surface of a decorative board having a brick, tile, or stone embossed pattern can be obtained by a simple method.
