Example Embodiment

[0027] Example 1: A UV-proof and waterproof mobile phone hardened film, such as figure 1 As shown, it includes a film body, which is sequentially provided with a first release film layer 1, a base layer 2, an anti-ultraviolet layer 3, a waterproof layer 4, and a second release film layer 5 from bottom to top. The constituent materials of layer 3 are calculated in parts by weight as follows: 20 parts of nano titanium dioxide, 40 parts of benzotriazole, 15 parts of dibutyl phthalate, 14 parts of epoxy resin and 1 part of diluent. The constituent raw materials are calculated in parts by weight as follows: 30 parts of polyurethane resin, 20 parts of butyl acetate, 10 parts of chloroalkyl ester and 1 part of phosphor.

[0028] The diluent is at least one of ethylene glycol, propanol and isobutanol.

[0029] The phosphor is at least one of europium oxide phosphor, cerium oxide phosphor, aluminum oxide phosphor, and barium oxide phosphor.

[0030] The base layer 2 is a BOPET film layer or...

Example Embodiment

[0036] Example 2: A UV-proof and waterproof mobile phone hardened film, such as figure 1 As shown, the rest is the same as in Example 1, the difference is that the composition of the anti-ultraviolet layer 3 is based on the following parts by weight: 25 parts of nano titanium dioxide, 50 parts of benzotriazole, 20 parts of dibutyl phthalate Parts, 16 parts of epoxy resin and 2 parts of diluent. The raw materials of the waterproof layer 4 are calculated in parts by weight: 35 parts of polyurethane resin, 45 parts of butyl acetate, 15 parts of chloroalkyl ester and 3 parts of phosphor, The thickness of the waterproof layer 4 is 10 μm, the thickness of the UV-proof layer 3 is 6 μm, the thickness of the base layer 2 is 12 μm, the first release film layer 1 and the second release film layer 5 The thickness is 13μm.

Example Embodiment

[0037] Example 3: A UV-proof and waterproof mobile phone hardened film, such as figure 1 As shown, the rest is the same as in Example 1, the difference is that the composition of the anti-ultraviolet layer 3 is based on the following parts by weight: 30 parts of nano-titanium dioxide, 60 parts of benzotriazole, 25 parts of dibutyl phthalate Parts, 18 parts of epoxy resin and 3 parts of diluent. The raw materials of the waterproof layer 4 are calculated in parts by weight: 40 parts of polyurethane resin, 60 parts of butyl acetate, 20 parts of chloroalkyl ester and 5 parts of phosphor, The thickness of the waterproof layer 4 is 20 μm, the thickness of the UV-proof layer 3 is 10 μm, the thickness of the base layer 2 is 15 μm, the first release film layer 1 and the second release film layer 5 The thickness is 15μm.

Abstract

The invention discloses an anti-ultraviolet and waterproof mobile phone hardening film, which comprises a film body, wherein the film body is sequentially provided with a first release film layer, a substrate layer, an anti-ultraviolet layer, a waterproof layer and a second release film layer from bottom to top. Composition raw materials of the anti-ultraviolet layer comprise nanometer titanium dioxide, benzotriazole, dibutyl phthalate, epoxy resin and a diluting agent, wherein the weight ratio of the nanometer titanium dioxide to the benzotriazole is (3:1) to (1:2); the weight ratio of the dibutyl phthalate to the epoxy resin is (3:2) to (2:3); the composition raw materials of the waterproof layer comprise urethane resin, butyl acetate, cathyl chloride and fluorescent powder, wherein the weight ratio of the polyurethane resin to the n-butyl acetate is (2:1) to (1:2); the weight ratio of the cathyl chloride to the fluorescent powder is (10:1) to (2:1). By using the mode, the anti-ultraviolet and waterproof mobile phone hardening film has the advantages that the ultraviolet rays of the mobile phone screen can be effectively shielded; the waterproof performance and the wear-resistance performance of the mobile phone protection film are improved; the service life of the mobile phone protection film is prolonged.

Description

technical field [0001] The invention relates to the technical field of protective films for electronic products, in particular to an anti-ultraviolet and waterproof hardened film for mobile phones. Background technique [0002] With the increasingly powerful functions of mobile phones, computers and other electronic products, people use mobile phones and computers to complete most of their work and daily needs. These devices may cause visual fatigue of human eyes and cause the occurrence of myopia. [0003] Therefore, it is very important to protect human health by inventing a protective film to be attached to the screen of an electronic product for shielding ultraviolet rays. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide an anti-ultraviolet and waterproof mobile phone hardening film, which can effectively shield the ultraviolet rays of the mobile phone screen, improve the waterproof and wear resistance of th...
