Abstract

The invention relates to an ultraviolet-cured high-adhesion scraping-resistant agent for a heat insulating film, which comprises the following components in part by mass: 15 to 25 parts of urethane acrylate oligomer, 10 to 17 parts of acrylate reactive diluent, 40 to 50 parts of solvent, 8 to 12 parts of adhesion promoter, 0.5 to 1 part of leveling agent and 5 to 10 parts of photoinitiator. The urethane acrylate oligomer is taken as matrix resin, has urethane bonds and forms various hydrogen bonds among molecular chains of high polymer, so that the cured product has excellent wear resistance and flexibility; and the solvent is used for enhancing the dissolution and dispersion of the components so as to solve the problem of formation of crystals. The adhesion promoter forms molecular anchor with a base material, and forms physical bonding or a firm chemical bond with the base material to enhance the adhesion. The ultraviolet curing speed is high, equipment cost is low, the pollution is light, and the invention provides a new energy-saving and environment-friendly technology.

Description

technical field [0001] The invention relates to the fields of chemical materials and optics, and is an ultraviolet-cured high-adhesion scratch-resistant agent coated on the surface of a heat-insulating film, which is used in automobiles and buildings to improve the performance and strength of glass. Background technique [0002] Heat insulation film is a multi-layer multi-functional polyester composite optical-grade special film product, which is used in the field of automobiles and buildings. , energy saving, explosion-proof, anti-ultraviolet, shielding privacy and safety protection and other functions, in recent years, heat insulation film has been widely used in China. [0003] Scratch-resistant agent is a material coated on the surface of the heat insulation film to prevent scratches. It can make the heat insulation film anti-scratch and bright in appearance. It has become an important part of high-grade heat insulation film. The high-grade insulation film requires high...
