Abstract

The invention discloses a blue-light-prevention screen protective membrane and a preparation method of the blue-light-prevention screen protective membrane, wherein the blue-light-prevention screen protective membrane is composed of a scrape-resistant coating, a film substrate layer, a blue light blocking layer and a release membrane layer; one surface of film substrate layer is coated by the scrape-resistant coating; the other surface of the film substrate layer is coated by the blue light blocking layer; the other surface of the blue light blocking layer is coated by the release membrane layer. The blue light blocking layer consists of the following components in parts by mass: 150 parts of methyl MQ silicon resin, 80-120 parts of terminated polydimethylsiloxane, 4.14-5.94 parts of 2, 4-dichlorobenzoyl peroxide, 0.27-5.06 parts of benzotriazole and 0.027-0.115 part of azo-type benzidine yellow. The blue-light-prevention screen protective membrane provided by the invention can resist blue light with the wavelength of 380-480nm, reduces the injury of blue light to retina, moreover has favorable visible light transmittance, and can be effectively compatible with visible light transmittance and blue light blocking rate; the coating is uniform and controllable in thickness; the preparation process is simple and low in cost.

Description

technical field [0001] The invention relates to an anti-blue light screen protective film and a preparation method thereof. Background technique [0002] Among the rays of light that are exposed to, the most harmful to the eyes mainly come from three categories: ultraviolet rays, infrared rays and blue light. Among them, blue light is an important part of visible light, which includes high-energy short-wave blue light from 380nm to 410nm and short-wave blue light from 420nm to 480nm. Blue light has extremely high energy and can penetrate the lens directly to the retina. Blue light irradiation on the retina will produce free radicals, which will lead to the decline of retinal pigment epithelial cells, resulting in a lack of nutrients for photosensitive cells and causing visual impairment. [0003] Modern flat panel displays, TFT film screens, LEDs, fluorescent lamps, liquid crystal displays, etc. all have backlight sources, and the light sources excited by the powerful elec...
