[0003]

The conventional artificial marble is inferior in flexibility, so that it is difficult to perform post-processing or bending on-site in correspondence with a deformed and protruding wall surface or a deformed substrate having a curved surface or the like. there were. Therefore, an artificial marble product having a shape corresponding to the deformed or deformed substrate having a curved surface has to be formed in a factory in advance using a mold. In addition, artificial marble products are packed and transported in the same shape, so they take up space and are extremely heavy, so that transportability and workability are poor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a flexible, lightweight, transportable, flexible, and deformable substrate having a curved surface. It is to provide an artificial marble product with good workability.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The artificial marble of the present invention is a flexible artificial marble obtained by adding a filler and / or a pigment to a urethane-modified vinyl ester resin or a urethane-modified vinyl ester resin. By using the urethane-modified vinyl ester resin, the discoloration of yellow can be suppressed in a high-temperature and high-humidity application site while ensuring flexibility. The artificial marble having a multilayer shape in which a surface layer is formed on the substrate layer using the artificial marble as a substrate layer. By forming the surface layer, contamination resistance is improved. In any case, the thickness of the artificial marble is set to 1.0 to 20.0 mm. When the thickness is less than 1.0 mm, the durability is poor and the moldability is also difficult. If it is 20.0 mm or more, the flexibility becomes poor, and it is difficult to wind and transport.

The material used for the surface layer may be a soft thermoplastic resin or a thermosetting resin. The surface layer may be formed by using a sheet such as an acrylic sheet or by spraying a soft acrylic-modified vinyl ester resin, urethane-modified vinyl ester resin, unsaturated polyester resin, or the like. The acrylic sheet is preferably a resin composed mainly of methyl methacrylic resin. When constituting a multilayer, the surface layer has a thickness of 10 to 500
It is made of a 0-micron resin material. If the thickness is less than 10 microns, the durability becomes poor and the moldability becomes difficult.
If it exceeds 5,000 microns, the flexibility becomes poor, and it is difficult to wind and transport.

[0009] When design properties are required, the surface layer may be transparent, translucent, or partially colored. By forming the transparent layer, the design can be enhanced because the depth can be formed in the product.

As the filler, stone pieces, cold water stone, calcium hydroxide, sodium hydroxide, calcium carbide and the like are used. By containing a filler, it is possible to form an artificial marble pattern and to reinforce the strength. When the filler is an inorganic filler, it is preferable to apply a silane-based surface treatment agent.

As a backup material, a metal plate, a ceramic plate, a calcium silicate plate, a cement plate or the like is used.
