Abstract

The invention relates to an ultraviolet-blocking window film. The ultraviolet-blocking window film consists of a scratch-resistant layer (1), a first polyester film or polyethylene film base material (2-1), a first ultraviolet-blocking pressure-sensitive adhesive layer (3-1), a second polyester film or polyethylene film base material (2-2), a second ultraviolet-blocking pressure-sensitive adhesive layer (3-2) and a release film (4) which are compounded into a whole, wherein the scratch-resistant layer (1) is obtained through ultraviolet curing after coating of a mixed material consisting of a scratch-resistant agent, ethyl acetate and methylbenzene; both the first ultraviolet-blocking pressure-sensitive adhesive layer (3-1) and the second ultraviolet-blocking pressure-sensitive adhesive layer (3-2) are obtained through thermosetting operation after coating of a mixed material consisting of a benzophenone ultraviolet absorbent, a benzotriazole ultraviolet absorbent, acrylic adhesive, a curing agent and a solvent. The ultraviolet-blocking window film can block ultraviolet lastingly.

Description

technical field [0001] The invention relates to a window film for blocking ultraviolet rays, which is especially 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. Therefore, there is an urgent need to develop a window film that can permanently block ultraviolet rays, so as to effectively protect the interior of buildings or cars and ensure the ...
