A kind of film material for eye protection computer screen

Abstract

The invention discloses an eye protection film material for computer screens. The eye protection film material comprises a wear layer, a blue ray absorbing layer and a release protective film layer which are arranged in sequence from top to bottom, and the wear layer and the blue ray absorbing layer are connected and the blue ray absorbing layer and the release protective film layer are connectedcorrespondingly through respectively independent transparent adhesive layers. The blue ray absorbing layer is prepared by using an addition polymer formed by polymerization of monomers of 4',4'',4''',4''''-(1,1,2,2-ethenetetrayl)tetra(4-biphenylcarboxylic acid), acrylonitrile, vinylethylene carbonate and 1-allyl-3-vinylimidazolium chloride as a substrate, then performing ion exchange and adding anadditive. The wear layer is prepared by blending a condensation and polymerization product of transparent nylon, 1,3-adamantanedicarboxylic acid and dihydralazine. The invention further discloses a preparation method of the eye protection film material for the computer screens. The eye protection film material for the computer screens prepared by the preparation method has an obvious eye protection effect and good anti-friction performance, and can effectively reduce the transmittance of harmful blue rays while ensuring the high transmittance of favorable blue rays.

Description

technical field [0001] The invention relates to the technical field of thin film display, in particular to an optical film applied to computer screens to protect eyes and prevent blue light. Background technique [0002] With the advancement of science and technology and the popularization of electronic digital products, electronic equipment has become an indispensable item in people's daily life. These electronic equipment are generally equipped with LCD screens. The LCD screen uses the physical characteristics of liquid crystals. The arrangement becomes orderly, allowing light to pass through easily, and the arrangement becomes chaotic when no electricity is applied, preventing light from passing through. The computer is the most common type of electronic equipment. When the computer is in use, the computer screen emits a large amount of high-energy short-wave blue light. These blue lights continue to irradiate our eyes and cause eye dysfunction. These extremely high-energ...

Problems solved by technology

[0007] In order to overcome the defects in the prior art, the present invention provides an eye-protecting computer screen film material, which overcomes the ubiquitous process complexity, high cost, blue light and The ultraviolet absorption rate and light transmittance are low. While absorbing harmful blue light, it also reflects or absorbs beneficial blue light, resulting in technical problems of distorted object color display. It has remarkable eye protection effect and good friction resistance. It can ensure beneficial blue light. With high transmittance, it can effectively reduce the transmittance of harmful blue light
