Abstract

The invention relates to a preparation method of an anti-reflection PET film for a liquid crystal writing board. The preparation method comprises the following steps: a, preparing an anti-reflection coating solution; b, coating an anti-reflection coating solution; c, preparing antiskid wear-resistant coating liquid; d, coating anti-skid wear-resistant coating liquid; e, pressing anti-dazzle textures; and f photocuring. The coating layer is a polymer layer mainly composed of acrylic monomers, so that the PET film has high hardness and can be prevented from being scratched, and the service life is prolonged; and the anti-dazzle textures can avoid light reflection, the anti-skid effect and the wear-resisting effect can be achieved, and the writing hand feeling is improved. Besides, the random copolymer latex particles are uniformly distributed on the PET film, micropores among the particles can be generated due to the arrangement of the latex particles, the refractive index of the surface of the PET film is reduced, and the light transmittance of the PET film is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal writing board production, in particular to a method for preparing an anti-reflection PET film for liquid crystal writing boards. Background technique [0002] Liquid crystal electronic writing board is an electronic device that adopts high-tech flexible liquid crystal technology, relies on pressure sensing to display text, patterns and graphics, and can complete writing with a single stroke and a light touch. PET film is an essential part of the liquid crystal writing board. The quality of the PET film directly affects the quality of the liquid crystal writing board. The existing PET film has a low surface hardness and is easy to be scratched and worn, thereby shortening the service life of the PET film. In addition, the existing PET film has poor light transmission effect, which affects people's use. Contents of the invention [0003] The invention aims to solve the deficiencies of the ...
