Abstract

The invention provides a blue-light-proof film. The blue-light-proof film includes a release protection film, a mounting adhesive, a PET layer, a blue-light-proof adhesive sticky layer, a blue light absorbing layer and a wear resistant layer which are arranged sequentially; the blue-light-proof adhesive sticky layer is made of raw materials of an organosilicone adhesive, methyl acrylate, nanometer cobalt oxide, phthalic dimethylamine, benzoyl peroxide, hexamethylphosphoric triamide and isocyanate curing agent. Compared with the prior art, the nanometer cobalt oxide in the blue-light-proof adhesive sticky layer of the blue-light-proof film of the invention can well absorb blue light, and the phthalic dimethylamine and the hexamethylphosphoric triamide act cooperatively so as to further improve a blue light absorbing effect, and thus, the blue-light-proof film can assuredly have an excellent blue light filtering effect. As indicated by experiment results, the blue-light-proof film can filter out about 90% of blue light, and the light transmittance of the blue-light-proof film is more than 90%.

Description

technical field [0001] The invention relates to the field of thin film technology, in particular to an anti-blue light film. Background technique [0002] Solar radiation is a type of electromagnetic radiation, which can be divided into several bands. The wavelengths shorter than 0.4 microns are called ultraviolet bands, those from 0.4 microns to 0.78 microns are called visible light bands, and electromagnetic waves with wavelengths in the range of 0.78-1000 μm are called infrared rays. In visible light, there is a kind of high-energy visible light-blue light. Blue light is the part of visible light closest to ultraviolet light with the highest energy. It accounts for 60% of white light. Its wavelength is between 380-500nm. Chronically exposed to blue light, the pigments in the cells will promote the reaction of phototoxins, and the retinal cells are more likely to be damaged. Blue light will pass through the cornea and lens and touch the retina. Blue light will accelerate...
