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. Therefore, it is urgent to develop a durable UV blocking window film to effectively protect the interior of buildings or cars and ensure the health of occupants

[0025] Example Preparation of UV blocking window film
[0026] The specific operation is as follows:
[0027] (A) Prepare raw materials
[0028] ① Prepare the base material
[0029] A polyester film substrate 2 with a thickness of 53 μm, and the polyester film substrate 2 is an aluminized polyester film; prepare a release film 4 with a thickness of 23 μm;
[0030] ②Preparation of mixed materials to form anti-scratch layer
[0031] The mass ratio of anti-scratch agent: ethyl acetate: toluene is 4 to 50: 1 to 15: 2 to 35 to prepare the above-mentioned components, and mix them evenly to obtain a mixed material forming an anti-scratch layer, which is stored for future use. Among them, the anti-scratch The scraping agent is UV-cured polyurethane acrylate coating BW1001 produced by Danyang Zhongshun Chemical Co., Ltd. Its appearance is a colorless transparent liquid, and its solid content is 46wt% to 50wt%, (measured at a temperature of 150°C); acetic acid Ethyl ester and toluen...

The invention relates to an ultraviolet-blocking window film. The ultraviolet-blocking window film consists of a scratch-resistant layer (1), a polyester film or polyethylene film base material (2), an ultraviolet-blocking pressure-sensitive adhesive layer (3) and a release film (4) which are compounded into a whole, wherein the scratch-resistant layer (1) is bond on one surface of the polyester film or polyethylene film base material (2) through ultraviolet curing; the ultraviolet-blocking pressure-sensitive adhesive layer (3) is bond on the other surface of the polyester film or polyethylene film base material (2) through ultraviolet curing; the release film (4) is compounded on the outer surface of the ultraviolet-blocking pressure-sensitive adhesive layer (3); 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; the ultraviolet-blocking pressure-sensitive adhesive layer (3) is 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 UV-blocking window film, 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 durable UV-blocking window film to effectively protect the interior of buildings or cars and ensure the health of occupants.
