Description

Technical Field

[0001] The utility model relates to the technical field of window films, and specifically relates to a wear-resistant window film with tensile resistance and ultraviolet protection. Background Art

[0002] Window films are attached to various windows, which have the functions of heat insulation and preservation, and at the same time have the effect of safety explosion prevention. When the glass is broken, the glass can maintain its original shape and will not splash everywhere, improving safety;

[0003] For example, a window film with the publication number of CN111107993B. The window film of this application includes a light-transmissive base material layer, an infrared reflection layer, an outer coating layer, and a protective film that can be peeled off from the outer coating layer. The window film with the above structure can achieve high functions even after construction;

[0004] Another example is a window film with the publication number of CN204451404U. The window film includes: a wear-resistant layer, a transparent polyethylene plastic film substrate deposited with a heat insulation functional layer, an anti-oxidation layer, a first acrylic adhesive layer, a protective film layer, a second acrylic adhesive layer, and a release film stacked in sequence from bottom to top; wherein, the anti-oxidation layer is a resin coated on the transparent polyethylene plastic film substrate deposited with a heat insulation functional layer by a coating process, and the thickness of the anti-oxidation layer is 1 to 10 μm. The resin-type anti-oxidation layer with a uniform thickness of at least 1 μm can completely cover the nano-level metal layer, effectively protecting the metal layer in the heat insulation functional layer from being oxidized, which is beneficial to improving the performance of the anti-oxidation layer and extending the service life of the reflective window film. The coating method can accurately control the coating thickness of the resin according to actual needs, with simple process, convenient operation, fast production speed, and suitable for large-scale industrial production;

[0005] During the use of window films, various accidental scratching situations may occur. After long-term use, there are many traces on the surface of the window film. At the same time, during the use process, the window film will be exposed to the sun, which will affect the subsequent use of the window film. However, the window films in the above applications do not have good wear resistance and tensile resistance effects during use, bringing unnecessary troubles to users. At the same time, they do not have good ultraviolet protection effects. When the sunlight is strong, ultraviolet rays will cause great damage to users.

[0006] In view of the above problems, there is an urgent need to innovate and design on the basis of the original window film. Content of the Utility Model

[0020] Furthermore, during use, the lower stretching layer on the upper surface of the first wear-resistant layer optimizes the overall stretchability of the window film, and elastic filaments are evenly distributed inside the lower stretching layer, optimizing the overall stretching effect of the window film;

[0021] (2)For this wear-resistant window film with tensile strength and UV resistance, the second wear-resistant layer on the upper surface of the lower stretching layer optimizes the overall wear resistance of the window film. At the same time, the upper stretching layer on the upper surface of the second wear-resistant layer also optimizes the overall stretchability of the window film. During use, the UV protection layer on the upper surface of the upper stretching layer prevents users from being burned by ultraviolet rays, improving safety;

[0035] The upper stretch layer 5 is heat-sealed to the upper surface of the second wear-resistant layer 4, and the upper surface of the upper stretch layer 5 is heat-sealed to the UV protection layer 6 and the antistatic layer 7, and the antistatic layer 7 is heat-sealed to the upper surface of the UV protection layer 6.

[0036] The hydrophobic layer 1 is coated with PU varnish, the surfaces of the first wear-resistant layer 2 and the second wear-resistant layer 4 are coated with anti-scratch and wear-resistant agents, and the first wear-resistant layer 2 and the second wear-resistant layer 4 are dried inside an external oven at a drying temperature of 85°~125° and a drying time of 15 seconds~115 seconds.

[0037] Elastic threads 11 are provided throughout the interior of the lower stretch layer 3 and the interior of the upper stretch layer 5 , and the elastic threads 11 are distributed at equal intervals. The material of the elastic threads 11 is polyurethane fiber, and the material of the anti-ultraviolet layer 6 is polypropylene film.

[0038] Before use, the window film is first laminated to the desired position through the laminating layer 10 made of polyurethane film material. During use, the PU varnish on the surface of the hydrophobic layer 1 does not leave any water stains, thereby ensuring the overall neatness of the window film. When the window film is scratched, the anti-scratch and wear-resistant agent on the surface of the first wear-resistant layer 2 prevents the window film from being scratched. During use, the lower stretching layer 3 on the upper surface of the first wear-resistant layer 2 optimizes the overall stretchability of the window film, and the elastic threads 11 are evenly distributed inside the lower stretching layer 3, thereby optimizing the overall stretching effect of the window film.
