A conductive thermoplastic resin composition, according to the present invention, comprises: 100 parts by weight of a base resin including (A) 15 to 35 wt% of a rubber-modified aromatic vinyl-based graft copolymer having an average diameter of 2,000-5,000 Å and a core-shell structure, B) 5 to 15 wt% of a rubber-modified aromatic vinyl-based graft copolymer having an average diameter of 500-1,500 Å and a core-shell structure, and C) 50 to 80 wt% of an aromatic vinyl-based graft copolymer having a weight-average molecular weight of 70,000-120,000 g/mol; and D) 1 to 5 parts by weight of carbon nanotubes on the basis of the 100 parts by weight of the base resin. The conductive thermoplastic resin composition, according to the present invention, maintains excellent impact strength and enhances surface resistance through the dispersion of carbon nanotubes, and thus can be used for electrostatic painting without need for a primer treatment |
