The production method and process of PET safety protective film, pet protective film can be seen everywhere in industrial applications. The role of pet protective film is mainly used to protect the product from scratch and dust. We will explain the improved type of pet protective film in the current market. Pet safety protective film, the following editor will explain the production method and process of protective film for everyone. Introduction: The protective film, functionally speaking, is to put a layer of film on the physical objects we want to protect, so that it is not damaged. Now there are high translucent protective films, AG matte protective films, and mobile phone mirrors. Functional protective film such as film and privacy film. Polyethylene terephthalate (PET) is a highly crystalline polymer with excellent wear resistance, electrical insulation, flame retardancy, and heat aging resistance. Characteristics such as low water absorption and low water absorption rate. Therefore, PET protective film is widely used in electronic products such as computers, digital cameras and mobile phones. However, the existing PET protective film has poor scratch resistance and tear resistance, which reduces the PET protective film. For this purpose, we propose a PET safety protective film. Requirements for realization of pet safety protection film: In order to realize the above-mentioned PET safety protection film function, the technical solution is as follows: PET safety protection film includes a first PET film layer and a second PET film layer. The upper surface of the first PET film layer is fixedly connected with a Scratch coating, the bottom of the first PET film layer is fixedly connected with an antibacterial layer, the bottom of the antibacterial layer is fixedly connected with a TPU film layer, the bottom of the TPU film layer is fixedly connected with a hardened coating, and the bottom of the hardened coating is connected with the second PET film The upper surface of the layer is fixedly connected, and the bottom of the second PET film layer is fixedly connected with a flame-retardant silicone composite layer. The flame-retardant silicone composite layer includes a flame-retardant layer, a flame-retardant silicone mixed layer and a silicone layer. The first PET film layer and the anti-scratch coating layer and the antibacterial layer, and the second PET film layer, the flame-retardant silicone composite layer and the hardened coating layer are all connected by an OCA glue layer. A release film layer is fixedly connected to the bottom of the flame-retardant silicone composite layer. The flame-retardant silica gel mixed layer is a mixture of flame-retardant materials and silica gel. Compared with the existing pet protective film, the beneficial effects of the new PET safety protective film are as follows: 1. The utility model is fixedly connected to the scratch-resistant coating on the upper surface of the first PET film layer, and fixedly connected to the bottom of the second PET film layer. The flame-retardant silicone composite layer has effectively improved the scratch resistance, tear resistance and flame retardancy of the protective film, and the silicone layer has the ability to automatically absorb the screen glass, which can be applied to a certain arc of the screen, and has a fast The ability of evacuating bubbles improves the bonding effect between the protective film and the screen glass. 2. Through the effects of the first PET film layer, the second PET film layer and the hardened coating, the utility model can make the protective film have a better cushioning effect when it is subjected to explosions or greater impacts, and the explosion-proof effect is good. Safe and reliable.
