Heat-insulating protective film capable of preventing blue light and ultraviolet light and resisting fog

Abstract

The invention relates to a heat-insulating protective film capable of preventing blue light and ultraviolet light and resisting fog. The heat-insulating protective film is formed by a fog resisting layer (1), a first polyester film (2-1), a blue light-preventing heat-insulating adhesive layer (3), a second polyester film (2-2), an ultraviolet blocking pressure-sensitive adhesive layer (4) and a release film (5), and all the layers are combined into a whole; the blue light-preventing heat-insulating adhesive layer (3) is a mixed material formed by a compound light stabilizer, a heat-insulating material, an adhesive, a curing agent and a solvent and is used for coating the other surface of the first polyester film (2-1), and the ultraviolet blocking pressure-sensitive adhesive layer (4) is a mixed material formed by an adhesive, a curing agent, an ultraviolet absorbent and a solvent and is used for coating the other surface of the second polyester film (2-2). The heat-insulating protective film capable of preventing blue light and ultraviolet light and resisting fog provided by the invention can effectively protect human eyes from being harmed by blue light through being attached to glass surfaces of buildings and automobiles, and meanwhile, has the functions of blocking the ultraviolet light, insulating heat, resisting fog, and the like.

Description

technical field [0001] The invention relates to an anti-blue light, anti-ultraviolet and anti-fog heat insulation protective film, which is suitable for pasting on the glass surface of buildings and the like, and is also suitable for the glass surface of automobiles. Background technique [0002] Blue light is high-energy visible light with a wavelength of 380-500nm, among which short-wave blue light of 380-440nm can stimulate the retina to excite free radical ions, cause the retinal pigment epithelial cells to shrink, and then cause the death of photosensitive cells, eventually causing blurred vision and gradual decline in vision Or even lose it completely. After the blue light enters the fundus and is focused, the focus does not fall on the retina, but falls between the retina and the lens, which increases the chromatic aberration distance for the light to focus in the eye. The injection of blue light will exacerbate chromatic aberration and blurred vision. At that time, ...

AI Technical Summary

Problems solved by technology

[0003] Buildings or cars have a large number of glass structures for the transmission of light, but the glass or glass window film on the market today does not have a good anti-blue light effect. There are a lot of high-energy light sources in sunlight and car headlights. Short-wave blue light, so under the above conditions, long-term exposure to blue light radiation will damage people's eyes and cause eye vision damage that is difficult to recover
