Abstract

The invention relates to the technical field of polymer films and particularly relates to an anti-ultraviolet blue light protection film. The protection film is a composite film compounded by a polyurethane layer and a polyester layer, wherein the polyurethane layer and the polyester layer are compounded by a compound adhesive layer; the compound adhesive layer is an adhesive coating containing an ultraviolet blue light absorbent; the adhesive is a PVB adhesive; the ultraviolet blue light absorbent is a compound agent prepared from modified or unmodified melanin powder, 2-hydroxy-4-methoxybenzophenone and titanium dioxide. The preparation method of the film is simple; the film has high light transmittance, is capable of effectively absorbing ultraviolet light and blue light, and can be applied to multiple fields such as electronic industrial products and automobile adhesion films and the like according to different thicknesses of the film.

Description

technical field [0001] The invention relates to the technical field of polymer films, in particular to an anti-ultraviolet blue light protective film. Background technique [0002] Blue light is a high-energy visible light with a wavelength of 380-500nm, which can penetrate the lens to reach the retina, causing the retinal pigment epithelial cells to die, resulting in a lack of nutrients for light-sensitive cells, causing irreversible vision damage, and blue light is tiny in the air. Particles have a high probability of scattering and are prone to glare. In addition, blue light can also stimulate the brain, inhibit the secretion of melatonin and increase the production of adrenal cortex hormones, thereby destroying the balance of hormone secretion and directly affecting sleep quality. Among them, short-wave blue light with a wavelength of 400-480 nanometers is the most harmful to the retina. The short-wave blue light in this range can stimulate the retina to excite free rad...
