POLYMER MORTAR COMPOSITION FOR PREVENTING ULTRAVIOLET DECOMPOSITION

摘要

PURPOSE: Provided is a polymer mortar composition for preventing deterioration and physical property change of structure in ultraviolet exposure without addition of ultraviolet light absorber. CONSTITUTION: The polymer mortar contains 100pts.wt. of polymer resin, 100-150pts.wt.(based on the resin) of filler, and 520-570pts.wt.(based on the resin) of aggregate whose maximum size is 0.25-0.29mm, where the polymer resin contains 87-93wt.% of unsaturated polyester resin, 6-10wt.% of cobalt octanoate and the balance of methylethylketone peroxide.
