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

Abstract

The invention discloses a common anti-scratch protective membrane. The main structure of the membrane comprises a main membrane, a mounting glue layer, a mounting glue protective membrane, an anti-scratch layer, a protective membrane glue layer and an anti-scratch layer protective membrane, wherein the main membrane, the mounting glue protective membrane and the anti-scratch layer protective membrane are polyethylene terephthalate (PET) membranes; and the mounting glue layer, the anti-scratch layer and the protective membrane glue layer are glue structures with different properties. The invention also discloses a manufacturing method for the common anti-scratch protective membrane. The common anti-scratch protective membrane can be arranged easily, air bubbles can be removed quickly and automatically, no glue is resided after the screen is removed, and the membrane can be recycled after the screen is removed; besides, the membrane has the functions of scratch resistance, high wear resistance, fouling resistance and the like and can be widely applied to screen protection of various liquid crystal displays. The manufacturing method for the common anti-scratch protective membrane is simple, convenient to operate and suitable for industrial protection.

Description

technical field [0001] The invention relates to a protective film, in particular to an ordinary anti-scratch 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 scratch res...
