大理石を得ることが出来なかった。Further, in order to further enhance the texture of natural marble, artificial marble (JP-A-59-171612) has been considered in which mica fragments are used as particles to exhibit a glittering feeling similar to natural stone. This conventional artificial marble is obtained by spraying mica pieces on the inner bottom surface of a molding die, then pouring in an unsaturated polyester resin containing crushed crushed rock, and then curing the same. . However, such conventional artificial marble does not have an appearance having a sense of depth like natural marble because mica pieces are arranged only in the plane direction.
Further, in order to solve such a problem, a method of spraying mica pieces in the thickness direction inside the mold is also conceivable, but this method is difficult, and an artificial marble having an appearance with a sense of depth is obtained. I couldn't do that.

As the transparent curable resin liquid in the present invention, a curable resin liquid such as an unsaturated polyester resin or acrylic syrup is suitably used. As the unsaturated polyester resin, a composition containing an unsaturated polyester prepolymer and a polymerizable monomer is used.

When the average of the maximum particle size of the mica pieces is less than 7 mm, a patchy pattern similar to a large-grain crystalline natural stone such as granite or marble cannot be obtained. Conversely, if the average of the maximum particle size of the mica pieces exceeds 20 mm, the moldability will decrease.

ある。The artificial stone having a mottled pattern according to the present invention comprises 1 to 50 parts by weight of mica fragments having an average maximum particle size of 7 to 20 mm, based on 100 parts by weight of the transparent curable resin liquid, and Since the resin molded product obtained by curing a composition containing 80 to 300 parts by weight of an inorganic filler having a diameter of 10 to 300 μm is used, the mica pieces may be in the planar direction and any Because they are arranged in an angled direction and light is reflected intricately by these mica fragments, they have a superior sense of depth and gloss compared to conventional artificial stones with patchy patterns, and granite It has the advantage of having an appearance very similar to large-grain crystalline natural stones such as lime and marble.

Furthermore, in the case of using mica pieces surface-treated with a silane coupling agent, the mica pieces are chemically bonded to the transparent curable resin liquid, so that the interface with the transparent curable resin liquid is strengthened. The adhesion between the resin and the transparent curable resin liquid is improved, and the strength is excellent. In addition, those using a transparent resin liquid containing reinforcing fibers also have excellent strength.
