Problems solved by technology

However, its hardness can only reach 4H, and it does not explain how to achieve the hardness and transmittance. There is no basis and it cannot be realized.
[0005] At present, the UV-cured hard coatings on the market mainly have the problems of low hardness and low light transmittance.
The hardness of the pencil is 1-3H, and it is easy to produce scratches after friction, which obviously cannot meet the requirements of our current living environment

Abstract

The invention discloses a PET three-layer scratch resistant protective film. The PET three-layer scratch resistant protective film comprises a protective layer, a use layer and a release layer, and the three layers are orderly bonded. The protective layer comprises a PET raw film and a silica gel layer. The use layer comprises a hardened coating, a PET raw film and a silica gel layer. The release layer comprises a PET raw film. The hardened coating of the use layer is bonded to the silica gel layer of the protective layer. The silica gel layer of the use layer is bonded to the PET raw film of the release layer. The PET three-layer scratch resistant protective film has hardened layer hardness greater than or equal to 5H, can resist friction of steel wool 0000#, has obvious scratch resistance, can effectively protect a screen, has light transmittance of 93% and has lasting and stable use effects and performances. The PET three-layer scratch resistant protective film has a service life 2-3 times that of a common hardened protective film in the market.

Description

technical field [0001] The invention relates to a protective film for an optical display screen, in particular to a PET three-layer anti-scratch protective film. Background technique [0002] With the continuous advancement of science and technology, more and more touch panels are used in display devices, but the passive wear of the touch panel will lead to the reduction of performance and aesthetics, and eventually lead to loss of use value and economic loss. Therefore, the hard coating that can be applied to the surface of the substrate has become a current research hotspot. [0003] Application No. 201310147481.4, a scratch-resistant PC film for optical display screens and its preparation method, discloses a scratch-resistant PC film for optical display screens, which uses PC film as the base material, and on the surface of the PC film It has a layer of 1-5 micron thick UV-cured acrylate coating. It is to apply a coating containing 1-20 parts by weight of photoinitiator...
