Colored anti-fog window film capable of insulating ultraviolet light

Abstract

The invention relates to a colored anti-fog window film capable of insulating ultraviolet light. The colored anti-fog window film consists of an anti-fog layer (1), a first polyester film or polyethylene film substrate (2-1), an ultraviolet insulating colored pressure-sensitive adhesive layer (3), a second polyester film or polyethylene film substrate (2-2), an ultraviolet insulating pressure-sensitive adhesive layer (4) and a release film (5) which are integrally compounded layer to layer, wherein the anti-fog layer (1) consists of hydrophilic thermocuring solvent type acrylic resin, propylene glycol monomethyl ether, dimethylformamide, a catalyst triethylene diamine, a flatting agent, isopropanol and ethanol; the ultraviolet insulating pressure-sensitive adhesive layer (4) consists of a mixture material which comprises a benzophenone ultraviolet absorbent, a benzotriazole ultraviolet absorbent, an acrylic acid adhesive, a curing agent and a solvent; the ultraviolet insulating colored pressure-sensitive adhesive layer (3) consists of the mixture of the ultraviolet insulating pressure-sensitive adhesive layer (4) and dyes. The colored anti-fog window film provided by the invention is long-lasting in insulating ultraviolet light, anti-fog and attractive in appearance.

Description

technical field [0001] The invention relates to a colored anti-fog 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 above-mentioned window film products rely on electric heating and the use of anti-fog coatings to achieve anti-fog. The former ha...

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 above-mentioned window film products rely on electric heating and the use of anti-fog coatings to achieve anti-fog. The former has a good effect but is expensive and wastes resources. The latter just sprays anti-fog coatings on glass and other surfaces, but cannot be cured. , so the anti-fog durability is poor and inconvenient to use, and the color is relatively single, which is not beautiful
