Problems solved by technology

Because it is tempered glass without certain toughness, such a protective film will be brittle fractured during processing and cannot be bent. At the same time, die-cutting is also very difficult, which greatly increases the cost of post-processing.

Abstract

The invention discloses an ultra-high hardness protection film having toughness, and a preparation method thereof, wherein the ultra-high hardness protection film is applied to display screens and mobile phone touch screens so as to provide protection, such that the long-term effective protection can be provided during use processes in the real sense. According to the present invention, the ultra-high hardness protection film of the present invention comprises a peeling layer, a use layer is introduced on the peeling layer, a film covering layer is introduced on the use layer, and the film covering layer, the use layer and the peeling layer form the protection film integrate structure; and the ultra-high hardness protection film has characteristics of super-strong wear resistance, super-strong scratch resistance, and good toughness, and the film can not produce cracks when the bending radian achieves 120 DEG.

Description

technical field [0001] The invention relates to an optical protective film, in particular to the field of manufacturing a liquid crystal display touch screen protective film. Background technique [0002] Touch screens can be seen everywhere in people's daily life, and more and more touch screen protective films are appearing around us. However, the hardness of the common protective film on the market is only 2-3H. Such a protective film is prone to scratches and scratches as the use time increases, which affects people's viewing of screen messages. Therefore, people have to frequently replace the new protective film to ensure the clarity and appreciation of the screen. This invisibly brings more economic waste to people in the usual use process, and also seriously affects people's mood in use. [0003] The newly developed protective film with high hardness on the market is mainly made of tempered glass as its layer. Because it is tempered glass without certain toughness...
