ACRYLIC SMC OR BMC, PROCESS FOR PRODUCING THE SAME, PROCESS FOR PRODUCING ARTIFICIAL ACRYLIC MARBLE, AND THICKENER

摘要

There are disclosed an acrylic SMC or BMC comprising an acrylic monomer or acrylic syrup (A), an inorganic filler (B) and a polymer powder (C) containing a remaining emulsifier in an amount from 0.01 to 0.95 wt% as constituent components; a method for producing an acrylic SMC or BMC comprising kneading the components at a temperature from 20 to 70 DEG C for thickening thereof using a kneader 8; a method for producing artificial marble comprising curing under heat and pressure this acrylic SMC or BMC; and a thickening agent composed of the polymer powder (C). These are useful for producing (meth)acrylic artificial marble having excellent various properties such as appearance, hot water-resistance and the like. <IMAGE>
