In particular, the present invention relates to a method for producing a patterned marble-like molded plate that is suitably used on the wall surface or floor surface of a building.

Description of the Related Art In recent years, artificial marble made of synthetic resins such as unsaturated polyester and methyl methacrylate resin has been used in place of natural stone. These are mainly used for counters, kitchen furniture tops, vanities, bathtubs, etc. as the interior of the building becomes more sophisticated. These artificial marbles are monochromatic and uniform consisting of resin and inorganic powder, or natural crushed stones or colored granular fillers are mixed to give a natural stone-like pattern. There are also those in which a transparent gel coat layer is provided, or inorganic gel particles, resin particle particles or fibers are added to the gel coat layer. Further, there is also one in which a mixture of two or more kinds having different color tones is lightly mixed so as not to be uniformly dispersed and molded, or a mixture having different colors is simultaneously poured at the time of pouring to give a flow pattern.
【０００３】しかし、これら人工大理石を壁面や床面に

た場合には、壁面や床面が単調になり、デザイン的にも
劣っていた。又、床に使用した場合、その表面が平滑に
なり、歩行中に滑り易いという問題もあった。However, when these artificial marbles are used on the wall surface or the floor surface, it seems that natural stones or marbles are used at first glance, but the surface is too flat and lacks a three-dimensional effect, resulting in poor luxury. Moreover, when these artificial marbles were used on the entire surface of the wall or floor, the wall surface or floor surface became monotonous and the design was inferior. Further, when used on the floor, the surface becomes smooth, and there is a problem that it tends to slip during walking.

Further, it is difficult for the surface to have a three-dimensional effect, and it is difficult to improve the slip prevention property during walking. Further, if the depth of the recess exceeds 5 mm, the amount of the curable composition to be filled becomes large and the filling operation becomes difficult, which is not preferable. When the recess has a groove shape, there is no particular problem as long as the width is 1 mm or more, but it is preferably 2 mm to 10 mm. The width of the recess is 1 mm
When it is less than 3, the design is poor, the surface is less likely to have a three-dimensional effect, and the slip resistance during walking is difficult to improve.

To improve. It is also intended to improve the durability and the like of the curable composition filled in the recesses, and to impart the effect of suppressing shrinkage and distortion when the curable composition is polymerized. The addition amount of the filler is preferably 400 parts by weight or less with respect to 100 parts by weight of the curable compound. If the amount added exceeds 400 parts by weight, the viscosity of the mixed solution becomes too high and filling becomes difficult. Further, the strength after curing is deteriorated, and the color and texture are deteriorated, resulting in poor design and three-dimensional appearance.

Semi-transparent pale cream color obtained by adding 50 parts by weight of urethane acrylate, 50 parts by weight of hydroxyethyl methacrylate, and 3 parts by weight of a photopolymerization initiator (IRGACURE 651, manufactured by Ciba-Geigy Co., Ltd.) to the concave portion of the marble-like molded plate. The curable composition of 1. was added and injected using a polyethylene drip bottle. Then, the curable compound protruding from the concave portion is scraped off with a rubber spatula to form a uniform surface with the surface of the molded plate, and then the curable composition is irradiated with an ultraviolet irradiation device (manufactured by Eyegraphic Co., Ltd.) for 30 seconds. It was cured to obtain a patterned marble-like molded plate.

滑り防止効果に優れていた。The obtained patterned marble tone molded plate is prepared by using a curable composition having a color tone different from that of the marble tone molded plate.
The surface was excellent in design and had a three-dimensional effect on the surface. Further, this molded plate is formed in a state in which its surface is indented into a U shape due to the curing shrinkage of the curable composition filled in the recesses, and when used as a floor material, it has an effect of preventing slippage during walking. Was excellent.

行時の滑り防止効果を生じさせることができる。INDUSTRIAL APPLICABILITY The method of the present invention is a simple method in which a concave portion such as a groove or a depression is formed on the surface of a marble-like molded plate, and the concave portion is filled with a curable composition to be cured. It is possible to improve the design of the toning plate and to give the surface a three-dimensional effect. Therefore, the patterned marble-tone molded plate obtained by the method of the present invention can impart a high-class feeling when used as a building interior material. In particular, even if it is used on a large area such as a wall or floor, it does not become monotonous, and an excellent design can be obtained. In addition, the marble-tone molded plate obtained by the method of the present invention is such that the curable composition is raised in the recesses, dented, or a granular filler is applied from the surface of the curable composition filled in the recesses. When it is used as a flooring material, the effect of preventing slippage during walking can be obtained by making it protrude.

なる。Also, if the area defined by the grooves is too small or too large, the surface is less likely to have a three-dimensional effect. Especially when anti-slip properties when walking are required,
A suitable area is 1 cm 2 to 400 cm 2 . Further, in the case of a depression having a concave shape, even if the area is too small or too large, a three-dimensional effect hardly occurs on the surface.
