The present invention relates to the field of window film technology, in particular to an anti-ultraviolet masterbatch, a BOPET window film and a preparation method. The anti-ultraviolet masterbatch includes a polyester resin, an anti-ultraviolet composition and a dispersant, and the anti-ultraviolet composition is Core-inner shell-outer shell structure composition, the core is nano-infrared ore powder, the inner shell is a titanium dioxide layer, and the outer shell is a polyacrylamide layer. The anti-ultraviolet masterbatch of the present invention makes the BOPET window film of the present invention have good light transmittance, anti-ultraviolet property and thermal insulation through the heat absorption effect of nano-infrared ore powder, the ultraviolet shielding effect of titanium dioxide and the light concentrating effect of polyacrylamide And far-infrared health care function, great application prospects. |
