Colored heat insulation window film for blocking ultraviolet light

Abstract

The invention relates to a colored heat insulation window film for blocking ultraviolet light. The colored heat insulation window film is formed by compounding a scratch resisting layer (1), a first polyester film or polyethylene film base material (2-1), a dyeing heat insulation adhesive layer (3), a second polyester film or polyethylene film base material (2-2), an ultraviolet blocking pressure sensitive rubber layer (4) and a release film (5), wherein the scratch resisting layer (1) is obtained by carrying out coating and then ultraviolet curing on a mixture prepared from a scratch-resistant agent, ethyl acetate and methylbenzene; the dyeing heat insulation adhesive layer (3) is obtained by coating and then thermocuring a mixture prepared from a heat insulation substance, an adhesive, a curing agent, butanone, methylbenzene and dyes; the ultraviolet blocking pressure sensitive rubber layer (4) is obtained by coating and then thermocuring a mixture prepared from a benzophenone ultraviolet absorber, a benzotriazole ultraviolet absorber, an acrylate adhesive, a curing agent and a solvent. The window film can permanently block the ultraviolet light, has the effects of heat insulation and energy conservation, and is beautiful in appearance.

Description

technical field [0001] The invention relates to a colored heat-insulating window film for blocking ultraviolet rays, which is particularly suitable for pasting on the glass surface of buildings or cars. Background technique [0002] Furniture, carpets, art paintings, curtains and other fabrics in buildings or automotive interiors will accelerate aging under sunlight or strong artificial light, especially under ultraviolet light, which will cause photooxidative degradation and greatly shorten their service life. , most domestic window film products have problems such as poor UV shielding performance and poor aging resistance, that is, the blocking rate of window film to ultraviolet rays is less than 90%, and as the use time continues to increase, the appearance and physical properties of the window film also deteriorate. It will gradually decline, and the heat insulation and energy saving effect is general, the color is relatively single, and the appearance is not beautiful. ...

AI Technical Summary

Problems solved by technology

[0002] Furniture, carpets, art paintings, curtains and other fabrics in buildings or automotive interiors will accelerate aging under sunlight or strong artificial light, especially under ultraviolet light, which will cause photooxidative degradation and greatly shorten their service life. , most domestic window film products have problems such as poor UV shielding performance and poor aging resistance, that is, the blocking rate of window film to ultraviolet rays is less than 90%, and as the use time continues to increase, the appearance and physical properties of the window film also deteriorate. It will gradually decline, and the heat insulation and energy saving effect is general, the color is relatively single, and the appearance is not beautiful. Therefore, it is urgent to develop a window film that can not only block ultraviolet rays for a long time, but also has a beautiful appearance and good heat insulation and energy saving effect, so as to effectively protect buildings. Or the interior of the car and to ensure the health of the occupants
