Abstract

A sunscreen automotive film is made from, by weight, 25 to 36 parts of PVC (polyvinyl chloride), 7 to 12 parts of nano-filler, 1.2 to 2.3 parts of anti-UV (ultraviolet) 531, 2 to 4 parts of PE (polyethylene) white masterbatch, 8 to 10 parts of bimodal PE, 4 to 6 parts of low-density polyethylene, 3 to 7 parts of low molecular weight polyisobutene, 2.5 to 4 parts of phenol formaldehyde resin, 0.2 to 0.4 part of antioxidant BHT, 12 to 18 parts of ethylene-vinyl acetate copolymer, 6 to 9 parts of methyl methacrylate, 7 to 10 parts of solvent, 1 to 1.5 parts of nanoscale Al2O3 powder, 1.2 to 2.2 parts of azo compound, 2 to 5 parts of polybutylene terephthalate, 0.2 to 0.5 part of foamer, and 0.6 to 0.9 part of cross-linking agent. The sunscreen automotive film is super-high in hardness and toughness, excellent in ultraviolet resistance, superior in performance and highly clear and has greatly improved anti-explosion performance.

Description

technical field [0001] The invention relates to an automobile film with sun protection function. Background technique [0002] Since the front windshield of the car is tempered safety glass, when the glass bursts, if the front windshield is installed, the fragments will not splash, which will protect the safety of the driver. However, if the special film for the front shield is not used or the manual installation is not good, it will seriously affect the driving, especially the driving safety of the owner at night. Car film is to paste a layer of film-like objects on the front and rear windshields, side windows and sunroofs of the vehicle, and this layer of film-like objects is also called solar film or explosion-proof heat insulation film. Car film, referred to as "car film", is a film that is attached to the car glass for beauty, safety and heat insulation. Its basic properties include safety, clarity, anti-glare, UV protection, heat insulation, anti-scratch, sufficient ...
