LUMINESCENT ARTIFICIAL MARBLE

摘要

PURPOSE: A phosphorescent artificial marble with excellent phosphorescent effect is provided to minimize the content of the phosphorescent pigment by using an unsaturated polyester resin, and a silica-containing compound and a phosphorescent pigment in the optimal rate. CONSTITUTION: A phosphorescent artificial marble comprises 7-10 weight% of a polyester resin (A), 85-91 weight% of a silica-containing compound (B), and 2-5 weight% of a phosphorescent pigment (C). The phosphorescent artificial marble has maximum luminance over 110mcd / m^2 and maintains the brightness over 7mcd / m for more than 1 hour. The silica-containing compound (B) includes a natural stone particle (B1) 50-80 weight% and an inorganic filler (B2) 20-50 weight% against silica-containing compound 100 weight%. The average particle diameter of the natural stone particle (B1) is 0.1-9.0mm. The inorganic filler (B2) is the silica powder with the average particle diameter is 20 μm or less. The average particle diameter of the phosphorescent pigment (C) is 6-150 μm.
