Thermal window film that blocks UV rays

Abstract

The invention relates to a heat insulation window film capable of blocking ultraviolet rays. The heat insulation window film comprises a scratch-resistant layer (1), a first polyester film or polyethylene film base material (2-1), a heat insulation adhesive layer (3), a second polyester film or polyethylene film base material (2-2), an ultraviolet blocking pressure sensitive adhesive layer (4) and a release film (5) which are compounded to form a whole body, wherein the scratch-resistant layer (1) is obtained by coating with a mixture of a scratch-resistant agent, ethyl acetate and methylbenzene and then carrying out ultraviolet curing; the heat insulation adhesive layer (3) is obtained by coating with a mixture of heat insulation substance, a bonding agent, a curing agent, butanone and methylbenzene and then carrying out thermal curing; the ultraviolet blocking pressure sensitive adhesive layer (4) is obtained by coating with a mixture of a diphenyl ketone type ultraviolet absorber, a benzotriazole type ultraviolet absorber, an acrylic acid bonding agent, a curing agent and a solvent and then carrying out thermal curing. The heat insulation window film not only is capable of blocking ultraviolet rays for a long time, but also has effects of heat insulation and energy conservation.

Description

technical field [0001] The invention relates to a 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 decrease, and the heat insulation and energy saving effect is general. Therefore, it is urgent to develop a window film that can not only block ult...

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 decrease, and the heat insulation and energy saving effect is general. Therefore, it is urgent to develop a window film that can not only block ultraviolet rays for a long time, but also has good heat insulation and energy saving effect, so as to effectively protect the interior of buildings or cars and ensure the health of occupants
