Embodiment

[0041] Choose a 50μm PET substrate 13, apply UV varnish glue on one side of the substrate 13 by dimple coating, and dry it in an oven at 50-130°C, 300-550mj / cm 2 Cured, the thickness is 2-3μm. UV varnish components: 30 parts of butanone, 30 parts of propylene glycol methyl ether acetate, 50 parts of hexanediol diacrylate, 30 parts of epoxy acrylic resin, 15 parts of polyurethane acrylic resin, 4 parts of benzophenone, and 1 part of triethanolamine share.

[0042] Coat the other side of the base material 13 with acrylic glue, apply it with a comma-type doctor blade, and cure it at 80-150° C. to obtain a 20 μm glue layer, and cover it with a release film 17 . Acrylic adhesive components: 50-60 parts of viscous monomer, 5-15 parts of internal polymeric monomer, 3-10 parts of modified monomer, and 0.1-1 part of crosslinking agent. The viscous monomer is 60 parts of butyl acrylate, the internal polymer monomer is 6 parts of vinyl acetate, 5 parts of methyl methacrylate, 5 parts o...

Abstract

The invention discloses a screen inner rupture-proof film, and a preparation method thereof. The screen inner rupture-proof film is adhered to the inner surface of a screen glass cover plate so as to realize protection of the screen. The screen inner rupture-proof film comprises a base material; one surface of the base material is coated with a UV varnish adhesive layer, and the other surface of the base material is coated with an acrylic adhesive layer; the other surface of the acrylic adhesive layer is coated with a release film; the thickness of the base material ranges from 20 to 100<mu>m, and the base material is prepared from one ingredient selected from PET, OPP, and PE; the release film is a PET release film with a thickness ranging from 50 to 150<mu>m; and the release force ranges from 3 to 20gf. According to the preparation method, one surface of the screen inner rupture-proof film is provided with the UV vanish adhesive layer, so that the screen inner rupture-proof film possesses impressionability, the screen inner rupture-proof film is printed with the shape and the appearance of the screen, and then the screen inner rupture-proof film adhered to the inner surface of the screen glass cover plate. The visual effect of the screen is seldom influenced because that the light-admitting quality of the screen inner rupture-proof film is high, and the screen inner rupture-proof film is printed with the shape and the appearance of the screen, and at the same time protection effect on the screen and electronic components in the screen is realized.

Description

technical field [0001] The invention relates to an optical protective film technology, in particular to an explosion-proof film in a screen. Background technique [0002] With the development of mobile phones, mobile phone protective films have also developed. Electronic display screens may be damaged or even burst due to external or internal impacts during use. The current protection method is generally to paste a protective film on the outside of the display screen, which has the advantage of being easy to operate. [0003] However, the protective film attached to the outside will turn yellow, edge up, or even fall off during use. Therefore, it needs to be replaced from time to time, resulting in a certain amount of waste. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an explosion-proof film inside the screen, which is pasted on the inner surface of the glass cover of the screen to ...
