PURPOSE: Provided is an acrylonitrile-styrene thermoplastic resin composition excellent in antimicrobial property, chemical-resistance, and weather-resistance, which contains an inorganic antimicrobial agent and an organic antimicrobial agent. CONSTITUTION: The thermoplastic resin composition comprises: (A) 100pts.wt. of a base copolymer resin containing an aromatic vinyl monomer and an unsaturated nitrile monomer, which has a weight average molecular weight of 90,000-200,000; (B) 0.5-3.0pts.wt. of the inorganic antimicrobial agent; (C) 0.1-1.0pts.wt. of the organic antimicrobial agent, wherein the ratio of the inorganic antimicrobial agent(B) and the organic antimicrobial agent(C) is 1:1-8:1 and the total amount of the inorganic antimicrobial agent(B) and the organic antimicrobial agent(C) is 0.5-3.0pts.wt. based on the base resin(A) of 100pts.wt. |
