Description

Technical Field

[0001] The present application relates to a protective film, in particular to a high-strength anti-scratch protective film. Background Art

[0002] Protective films can be divided into digital product protective films, car protective films, household protective films, food preservation protective films, etc. according to their uses. With the popularization of digital products such as mobile phones in China, protective films have gradually become a general term for screen protective films, and are widely used in the field of screen protection. Now there are functional protective films such as AR anti-reflective film, AG matte anti-reflective film, mobile phone mirror film, anti-peep film, high-definition anti-scratch film, etc.

[0003] Many high-strength anti-scratch protective films are difficult to align when pasted due to their certain thickness and high hardness. The inaccurate alignment after pasting may affect the visual effect of the screen, such as reducing the brightness, contrast and clarity of the screen, and even causing certain color deviation. In addition, since most high-strength anti-scratch protective films are difficult to clean after being contaminated, the visual effect of the screen will also be affected. Therefore, a high-strength anti-scratch protective film is proposed to address the above problems. Summary of the invention

[0004] In this embodiment, a high-strength anti-scratch protective film is provided to solve the problem that the high-strength anti-scratch protective film in the prior art is easily affected by uneven sticking or contamination during use, which affects the visual effect of the screen.

[0005] According to one aspect of the present application, a high-strength anti-scratch protective film is provided, comprising a protective film body; the protective film body comprises a high-strength anti-scratch film layer, an electrically insulating flexible layer, a linear low-density polyethylene flexible layer, an anti-blue light protective coating and an inner flexible protective layer, the bottom surface of the high-strength anti-scratch film layer is bonded and fixed with the electrically insulating flexible layer, and the bottom surface of the electrically insulating flexible layer is bonded and fixed with the linear low-density polyethylene flexible layer, the bottom surface of the linear low-density polyethylene flexible layer is bonded and fixed with the anti-blue light protective coating, and the bottom surface of the anti-blue light protective coating is bonded and fixed with the inner flexible protective layer.

[0006] Furthermore, a self-adhesive layer is provided on the bottom surface of the protective film body, and a side protective oil film is bonded to the bottom surface of the self-adhesive layer. A positioning film is symmetrically provided on one side of the protective film body, and the positioning film is breakpoint-connected to the protective film body through a breakpoint connecting film.

[0007] Furthermore, the high-strength anti-scratch film layer, the electrically insulating flexible layer, the linear low-density polyethylene flexible layer, the anti-blue light protective coating and the inner flexible protective layer are all fixed by high-pressure bonding.

[0008] Furthermore, the thickness of the electrically insulating flexible layer is less than the thickness of the linear low-density polyethylene flexible layer, and the thickness of the linear low-density polyethylene flexible layer is equal to the thickness of the high-strength anti-scratch film layer.

[0009] Furthermore, the thickness of the anti-blue light protective coating is equal to the thickness of the electrically insulating flexible layer, and the thickness of the inner flexible protective layer is greater than the thickness of the anti-blue light protective coating.

[0010] Furthermore, the thickness of the positioning film is smaller than the thickness of the protective film body, and the side surfaces of the two breakpoint connection films are aligned with the side edges of the protective film body.

[0011] Through the above-mentioned embodiments of the present application, a high-strength anti-scratch design for the surface layer is adopted. When in use, it cooperates with the inner electrically insulating flexible layer, the linear low-density polyethylene flexible layer and the inner flexible protective layer to greatly improve the flexibility of the protective film, so that the protective film can be easily aligned with the screen after bending during installation, thereby avoiding the impact of unevenness on the visual effect of the screen, and the anti-blue light protective coating can reduce the impact of pollution on the visual effect of the screen, thereby solving the problem that the existing high-strength anti-scratch protective film is easily affected by uneven pasting or pollution during use, thereby greatly improving the practicality of the protective film.
