Title:
THERMOPLASTIC RESIN COMPOSITION, METHOD FOR PREPARING SAME, AND MOLDED PRODUCT COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/033404
Kind Code:
A1
Abstract:
The present disclosure relates to a thermoplastic resin composition, a method for preparing same, and a molded product comprising same and, more specifically, to a thermoplastic resin composition, a method for preparing same, and a molded product comprising same, the composition comprising: (A) 30 to 50 wt% of a polybutylene terephthalate resin; (B) 8 to 20 wt% of a polyethylene terephthalate resin; (C) 3 to 15 wt% of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer; (D) 3 to 15 wt% of an aromatic vinyl compound-vinyl cyanide compound copolymer; (E) 25 to 40 wt% of glass fibers; (F) 0.15 to 1 wt% of a carbodiimide-based compound; (G) 0.5 to 1.5 wt% of an epoxy compound; and (H) 0.25 to 1.2 wt% of a hindered amine-based light stabilizer. The present invention has an effect of providing a thermoplastic resin composition, a method for preparing same, and a molded product comprising same, wherein the composition has excellent heat resistance and mechanical properties, such as impact strength, tensile strength, flexural strength, and flexural modulus, as well as a superb flexural strength retention rate after the Air-HAST test, thereby satisfying the product reliability required for exterior materials and electronic component materials in a vehicle.
