Problems solved by technology

[0002] With the rapid development of the touch screen market, the requirements for the appearance of the touch screen are getting higher and higher. However, since the outer surface of the existing touch screen is generally tempered glass, it is impossible to complete the personalization with complex patterns and special effects in the non-window area around the tempered glass. Appearance printing, so there is an explosion-proof film attached to the outer surface of the touch screen on the market. By printing various patterns on the non-window area around the explosion-proof film, it can meet the individual requirements of consumers. At the same time, the explosion-proof film can also prevent the touch screen from being damaged. Fragments scattered by external impact
[0003] At present, there are many kinds of commercialized antibacterial and explosion-proof protective films on the market, which have good anti-scratch and impact functions, but they still have the following problems: easy to fade and warp, and cracks will appear in severe cases, which will affect the service life. Has antibacterial function

Abstract

The invention discloses a safe explosion-proof membrane and a preparation method thereof. The explosion-proof membrane comprises a PET carrier layer, wherein a first functional layer is arranged on one surface of the PET carrier layer, a second functional layer is arranged on the other surface of the PET carrier layer, and protecting membrane layers are arranged on the outer surfaces of the first functional layer and the second functional layer. The preparation method of the explosion-proof membrane comprises the steps of preparing the first functional layer, preparing the second functional layer, preparing materials of the protecting membrane layers, and carrying out coating. The safe explosion-proof membrane is unlikely to fade and warp, has thermal-insulation, ultraviolet ray-blocking, anti-hitting and explosion-proof functions and is simple in preparation process, relatively low in cost and suitable for being taken as an outer-layer explosion-proof membrane of mobile phones and digital products.
