PURPOSE: A polycarbonate resin composition is provided to have excellent heat resistance and flexural strength, by containing mica which is coated with a synthetic resin with an amino group with excellent surface adhesion to polycarbonate. CONSTITUTION: A polycarbonate resin composition comprises 100.0 parts by weight of polycarbonate, 5-30 parts by weight of synthetic resin-coated mica, and 0.1-5 parts by weight of a dispersant. The synthetic resin is a styrene acrylonitrile copolymer. The mica consists of 50-55 parts by weight of silicon oxide, 30-35 parts by weight of aluminum oxide, 5-10 parts by weight of potassium oxide, 0.5-1 parts by weight of ferric oxide. The dispersant is a styrene sodium acrylate copolymer of which weight average molecular weight is 1,000-100,000. |
