NON-HALOGEN FLAME RETARDANT POLYCARBONATE RESIN COMPOSITION WITH EXCELLENT FLAME RETARDANCY USING A PHOSPHORUS COMPOUND AS A FLAME RETARDANT

摘要

PURPOSE: An environment-friendly flame retardant polycarbonate-based resin composition is provided to ensure excellent flame retardancy and to avoid the generation of poisonous gas in processing or combustion. ;CONSTITUTION: A non-halogen flame retardant polycarbonate resin composition includes, based on 100 parts by weight of a base resin, 0.5~30 parts by weight of a phosphorous-based compound having a structure of chemical formula (I) or mixture thereof. The base resin consists of (A) 30-100 weight% of a polycarbonate resin and (B) 0-70 weight% of rubber-modified aromatic vinyl resin. In chemical formula (I), R1 and R2 are independently C1~10 alkyl group, and C5~7 cycloalkyl group or phenyl group.;COPYRIGHT KIPO 2011
