Abstract

The invention relates to the technical field of hardened films, particularly to an antifouling anti-fingerprint matte hardened film. The antifouling anti-fingerprint matte hardened film comprises a base material layer, wherein a matte coating is arranged on the upper surface of the base material layer, and the upper surface of the matte coating is coated with an organic silicon modified polyurethane acrylate coating. The hardened film is prepared from simple raw materials, easy to machine and low in cost, has excellent antifouling and anti-fingerprint effects and presents wide market prospects.

Description

technical field [0001] The invention relates to the technical field of hardened films, in particular to an antifouling and anti-fingerprint frosted hardened film and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's dependence on electronic products is getting stronger and stronger. Touch screens are widely used in electronic products such as tablet computers and smart phones. In order to prevent the touch screen from being scratched, consumers usually attach a protective film on the surface of the touch screen. However, since the hands are prone to sweating, a large number of fingerprints will be left when the sweat fat of the hands slides on the surface of the protective film, which seriously affects the appearance and sense of use. In order to obtain an anti-fouling and anti-fingerprint matte hardened film, in the prior art, a layer of fluorosilicon material is electroplated on the surface of the matte...
