THERMOPLASTIC RESIN COMPOSITION HAVING LESS AMOUNT OF TVOCS AND EXCELLENT MECHANICAL PROPERTIES

摘要

PURPOSE: A thermoplastic resin composition is provided to secure the impact strength, and the mechanical property including the flowage and heat resistance, and to prevent environment contamination by reducing the generation of total volatile organic compounds. CONSTITUTION: A thermoplastic resin composition contains 100 parts of base resin by weight, and 0.1~5 parts of porous silica nano particle by weight. The base resin is formed with 30~99 parts of styrene-based resin including an epoxy group by weight, and 1~70 parts of polyester resin. The average particle size of the porous silica nano particle is 5~800 nano meters. The average diameter of each pore is 1~80 nano meters. The styrene-based resin contains 5~100wt% of epoxy radical including vinyl copolymer, and 0~95wt% of rubber strengthening styrenic copolymer resin.
