A thermoplastic resin composition of the present invention comprises approximately 100 parts by weight of a rubber-modified aromatic vinyl-based copolymer resin, approximately 50-150 parts by weight of a polyalkyl (meth)acrylate resin, approximately 0.1-3 parts by weight of a silver (Ag)-based compound; and approximately 0.5-10 parts by weight of zinc oxide, wherein the zinc oxide is composed of primary particles and secondary particles, the average particle size (D50) of the primary particles, measured by means of a particle size analyzer, is approximately 1-50 nm, and the average particle size (D50) of the secondary particles is approximately 0.1-10 μm. The thermoplastic resin composition has excellent antibacterial property, thermal stability, transparency, metal texture and the like.

Thermoplastic resin composition and molded product manufactured therefrom

A thermoplastic resin composition includes: a first rubber-modified vinyl graft copolymer obtained by grafting a monomer mixture including an aromatic vinyl monomer and a vinyl cyanide monomer to a diene rubber polymer; a second rubber-modified vinyl graft copolymer obtained by grafting a monomer mixture including an aromatic vinyl monomer and a vinyl cyanide monomer to an acrylate rubber polymer; a first aromatic vinyl-vinyl cyanide copolymer having a weight average molecular weight of about 250,000 g/mol to about 450,000 g/mol and including about 25 wt % to about 31 wt % of a repeat unit derived from a vinyl cyanide monomer; a second aromatic vinyl-vinyl cyanide copolymer having a weight average molecular weight of about 70,000 g/mol to about 150,000 g/mol and including about 33 wt % to about 42 wt % of a repeat unit derived from a vinyl cyanide monomer; and a third aromatic vinyl-vinyl cyanide copolymer having a weight average molecular weight of about 70,000 g/mol to about 150,000 g/mol and including about 25 wt % to about 31 wt % of a repeat unit derived from a vinyl cyanide monomer. The thermoplastic resin composition can have excellent properties in terms of chemical resistance, stiffness, impact resistance, and the like.
