ARTIFICIAL MARBLE HAVING NATURAL PATTERN AND PARTIAL LUMINESCENT, AND METHOD OF PREPARING THE SAME

摘要

PURPOSE: Artificial marble is provided to have natural stone texture in a bright plate and a light accumulation effect in a dark plate by containing an unsaturated polyester resin, natural stone particles, inorganic filler, an organic/inorganic pigment, and a light accumulation chip at an optimum ratio. CONSTITUTION: Artificial marble contains 5-15wt% of unsaturated polyester resin, 75-92wt% of silica-containing compound, and 3-10wt% of amorphous light accumulation chip. The distribution area of the light accumulation chip on every cross section of the artificial marble is 3-10% of the cross section area of the artificial marble. The artificial marble additionally contains 0.01-1 parts by weight of organic/inorganic pigment for 100 parts by weight of the composition containing the unsaturated polyester resin, the silica-containing compound, and the light accumulation chip. The average particle diameter of the light accumulation chip is 0.1-5.6 mm.
