Abstract
This thermoplastic resin composition of the present invention comprises: approximately 100 parts by weight of a polycarbonate resin; approximately 1 to approximately 20 parts by weight of a rubber-modified vinyl-based copolymer resin; approximately 10 to approximately 30 parts by weight of a phosphorous-based flame retardant agent; approximately 3 to approximately 12 parts by weight of calcium carbonate; approximately 10 to approximately 40 parts by weight of talc; approximately 5 to approximately 11 parts by weight of wollastonite; and approximately 0.01 to approximately 5 parts by weight of a black pigment. The weight ratio of the calcium carbonate to the talc is approximately 1:1.5 to approximately 1:3.5, and the weight ratio of the talc to the wollastonite is approximately 1:0.3 to approximately 1:0.7. The thermoplastic resin composition can exhibit the properties of high gloss and a good outer appearance, and has excellent fluidity, impact resistance, heat resistance, thin film flame retardancy, and dimensional stability.
