Problems solved by technology

However, if the mobile phone is touched many times in a day, many bacteria will be left on its surface. Although the existing technology also has the technology to make the surface of the mobile phone protective film have the ability to sterilize, it has not yet seen both bactericidal function and anti-scratch function. The protective film appears

Abstract

The invention discloses a flexible screen protection film, which is characterized by comprising a base material, a sterilizing and hardening layer, a gluing layer and a release film, wherein the sterilizing and hardening layer is arranged on the first surface of the base material; the gluing layer is arranged on the second surface of the base material; the release film is stuck on the gluing layer; and in addition, the base material is a PU (Poly Urethane) film, a TPU (thermoplastic urethanes) film, a PO (Propylene Oxide) film or a PVC (Poly Vinyl Chloride) film; the sterilizing and hardening layer is plated on the base material by vacuum evaporation, vacuum ion plating or vacuum sputtering; and the sterilizing and hardening layer is pure copper, copper alloy or copper oxide. The invention also discloses a preparation method of the flexible screen protection film. Compared with the prior art, the flexible screen protection film has the advantages that the surface of the protection film has the functions of preventing from starching and sterilizing. The flexibility of the whole protection film is greatly increased, and no creases are generated in the folding or bending process.

Description

technical field [0001] The invention relates to a screen protection film of a digital product, in particular to a foldable and bendable flexible screen protection film, and also relates to a preparation method of the flexible screen protection film. Background technique [0002] The screens of digital products (mobile phones, MP4, PSP, portable computers) in the prior art are all planar, cannot be folded and bent, and are extremely inconvenient to carry. As a development trend, the screens of existing digital products (especially mobile phones) are equipped with a layer of screen protection film. Generally, PC protection film, PET protection film, and AR protection film are used. For such documents, please refer to the patent number It is the Chinese utility model patent "Screen Protective Film" of ZL200920169661.1 (authorized announcement number CN201514774U). This kind of protective film works well for non-foldable screens, but for foldable and curved screens, there will ...
