Problems solved by technology

[0003] However, the screen protectors currently used in the market are prone to bubbles when pasted and are not easy to discharge, which affects the aesthetics of the product after the film is applied. Moreover, the screen protectors currently used have low light transmittance and poor scratch resistance, and the protective film is still easy to be damaged by fingers. , pendants and other hard objects scratches, thus affecting the service life of the LCD screen

Embodiment 1

[0031] The specific steps of the manufacturing method of the above-mentioned anti-scratch and anti-fouling screen protective film are as follows:

[0032] (1) Coating a 25um installation adhesive layer 5 on the corona surface of the 100um main film PET substrate 4;

[0033] (2), use 50um installation adhesive protective film PET base material 6 to compound with installation adhesive layer 5;

[0034] (3), and then on the non-corona surface of the main film PET substrate 4, coat a layer of 2um anti-scratch glue solution added with hexafluorobutyl methacrylate. 2 Next, it is cured by UV to form a scratch-resistant layer 3;

[0035] (4) Coat a layer of 5um protective film adhesive layer 2 on the corona surface of another scratch-resistant layer protective film PET substrate 1 with a thickness of 50um, and compound it with the scratch-resistant layer 3 after coating to obtain this product The product described in the examples.

Abstract

The invention discloses a scratch-resistant stain-repellent screen protection film. The main structure of the scratch-resistant stain-repellent screen protection film comprises a main film, a mounting adhesive layer, a mounting adhesive protection film, a scratch-resistant layer, a protection film adhesive layer and a scratch-resistant layer protection film, wherein the three layers of the main film, the mounting adhesive protection film and the scratch-resistant layer protection film are film structures of polyethylene terephthalate (PET) material, and the three layers of the mounting adhesive layer, the scratch-resistant layer and the protection film adhesive layer are adhesive structures with different properties. The invention also discloses a making method of the scratch-resistant stain-repellent screen protection film. The scratch-resistant stain-repellent screen protection film provided by the invention is easy to mount, and capable of quickly and automatically removing bubbles; no adhesive residue is left on the screen surface after the scratch-resistant stain-repellent screen protection film is removed; the scratch-resistant stain-repellent screen protection film can be repeatedly sticked and used after being removed from the screen; and the scratch-resistant stain-repellent screen protection film has the functions of scratching resistance, excellent abradability, stain repellence and the like, and can be widely applied to screen protection of various liquid crystal display screens. The making method of the scratch-resistant stain-repellent screen protection film provided by the invention is simple, easy to operate and suitable for industrial production.

Description

technical field [0001] The invention relates to a protective film, in particular to an anti-scratch and anti-fouling screen protective film with anti-scratch function for protecting liquid crystal screens and a manufacturing method thereof. Background technique [0002] With the vigorous development of electronic technology, electronic products such as mobile phones, MP4, MP5, cameras, digital video cameras, and notebook computers are being introduced from old to new. In order to prevent the surface of the screen of the electronic product from being scratched or worn and affect the use effect, a screen protective film is generally attached to the screen surface of the electronic product. [0003] However, the screen protectors currently used in the market are prone to bubbles when pasted and are not easy to discharge, which affects the aesthetics of the product after the film is applied. Moreover, the screen protectors currently used have low light transmittance and poor scr...
