PURPOSE: To obtain an artificial marble having improved workability, uniformity, deepness of the appearance and designability by adding calcium carbonate having a specific primary particle diameter. CONSTITUTION: Calcium carbonate having a primary particle diameter of 0.01-0.5μm and optionally surface-treated with 1-10 pts.wt. (based on 100 pts.wt. of the calcium carbonate) of a fatty acid and/or a fatty acid soap is mixed with white marble, silica, mica, cured resin, etc., and the mixture is roughly crushed. The roughly crushed material is compounded to a resin in an amount of 0.1-50 pts.wt. based on 100 pts.wt. of the resin and the mixture is optionally incorporated with a filler, a curing catalyst, a cure accelerator, a shrinkage controlling agent, a stabilizer, a colorant and a thickener, kneaded and formed by casting. |
