THERMOPLASTIC RESIN COMPOSITION AND MOLDED PRODUCT FORMED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2020/138785
Kind Code:
A1
Abstract:
A thermoplastic resin composition of the present invention comprises: approximately 100 parts by weight of a polycarbonate resin; approximately 0.1-5 parts by weight of a rubber-modified aromatic vinyl-based copolymer resin; approximately 0.1-7 parts by weight of zinc oxide; approximately 0.01-2 parts by weight of a C10-20 alkyl phosphate; approximately 0.01-2 parts by weight of a maleic anhydride-graft polymerized rubber polymer; and approximately 0.01-2 parts by weight of a phosphite-based antioxidant, wherein the zinc oxide has an average particle size of approximately 0.5-3 μm, a specific surface area BET of approximately 1-10 m2/g, a 2θ value as the peak position, of 35-37°, in X-ray diffraction analysis, and a crystallite size, represented by relation 1, of approximately 1,000-2,000 Å. The thermoplastic resin composition has excellent antibacterial properties, weather resistance, impact resistance, heat resistance and the like.
