POLYESTER RESIN COMPOSITION AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/040735
Kind Code:
A1
Abstract:
The present invention relates to a polyester resin composition and a preparation method therefor and an application thereof. The polyester resin composition contains a PCT resin, a white pigment, a reinforcing material, a polyester elastomer, and other additives. The polyester resin composition provided by the present invention has a strong binding force with a silica gel; when the polyester resin composition is made into an LED reflecting support, the LED reflecting support is not easy to separate from the silica gel in high temperature and high humidity environments, such that the service life of an LED lamp bead can be effectively prolonged; and meanwhile, the polyester resin composition has good toughness, and would not cause the problem of powder falling under repeated stress.
