Document Type and Number:
WIPO Patent Application WO/2022/019410
Kind Code:
A1
Abstract:
The present invention relates to a thermoplastic resin composition and a molded article thereof and, more particularly, to a thermoplastic resin composition and a molded article thereof, the composition comprising: 100 parts by weight of base resin comprising A-1) 10 to 50 wt% of an acrylate-aromatic vinyl compound-vinylcyan compound graft copolymer comprising an acrylate rubber having an average particle diameter of 0.3 to 0.5 μm, A-2) 5 to 40 wt% of an acrylate-aromatic vinyl compound-vinylcyan compound graft copolymer comprising an acrylate rubber having an average particle diameter of 0.05 μm or more to less than 0.3 μm, and B) 20 to 65 wt% of an aromatic vinyl polymer; and C) 0.5 to 12 parts by weight of polyamide, wherein solvent resistance, measured as the time for cracking in a solvent consisting of 98 wt% of water, 1 wt% of citric acid, and 1 wt% of malic acid, is 15 days or more. According to the present invention, mechanical properties and processability are maintained at the same level or higher compared to conventional ASA-based resins, various colors can be implemented, and discoloration and cracks do not occur due to excellent solvent and chemical resistance, and thus there is an effect of providing a thermoplastic resin composition and a molded article thereof that are particularly suitable for industrial use of a cart.
