Abstract

The invention discloses a production method of a high-performance BOPET film. The BOPET film is composed of an outer surface layer, a middle core layer and an inner surface layer. The outer surface layer is composed of PET, PHB, PA6, p-hydroxybenzoic acid, terephthalic acid, ethylene glycol, LLDPE and an antioxidant 1010; the middle core layer consists of PET (Polyethylene Terephthalate), PBT (Polybutylene Terephthalate), PC (Polycarbonate), ABS (Acrylonitrile Butadiene Styrene), glass fiber, talcum powder and a copolymer of styrene-methyl methacrylate-glycidyl methacrylate; the inner surface layer is prepared from PET, titanium dioxide, zinc oxide, PBT, polyethylene oxide, TPU, nano silicon dioxide and triphenyl phosphate. The BOPET film designed by the method is higher in performance.

Description

technical field [0001] The invention relates to the technical field of BOPET films, in particular to a production method of high-performance BOPET films. Background technique [0002] BOPET film is a biaxially oriented polyester film. BOPET film usually has the characteristics of high strength, good rigidity, transparency, and high gloss, but it also has defects in use, so how to develop a BOPET film with better performance is The direction of research that workers in this field want to study. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present invention is to provide a production method of high-performance BOPET film. [0004] In order to solve the above-mentioned problems, the technical solution of the present invention is: a kind of production method of high-performance BOPET film, BOPET film is made up of outer surface layer, middle core layer and inner surface layer; [0005] The outer layer is compos...
