US 8,039,575 B2 · Flame-retardant polycarbonate resin composition, polycarbonate resin molded article, and method for producing the polycarbonate resin molded article

Abstract

Provided are a polycarbonate resin composition containing a glass filler, which is excellent in transparency, strength, and heat resistance and provided with high flame retardancy even without using a flame retardant, and a polycarbonate resin molded article obtained by molding the resin composition. The flame-retardant polycarbonate resin composition contains a combination including (A) 55 to 95 mass % of an aromatic polycarbonate resin containing a polycarbonate-polyorganosiloxane copolymer and (B) 45 to 5 mass % of a glass filler having a refractive index smaller or larger than a refractive index of the aromatic polycarbonate resin by 0.002 or less, and (C) 0.05 to 20.0 parts by mass of a silicone compound having a reactive functional group with respect to 100 parts by mass of the combination. The polycarbonate resin molded article has a thickness of 0.3 to 10 mm which is obtained by molding the composition.
