Abstract

The invention relates to the technical field of optical films and in particular relates to a preparation method and an application of a protective film in full lamination with a mobile terminal. The preparation method of the protective film comprises the following steps: putting a polyester film substrate and a first release film into a film coating and laminating wheel, carrying out hot-press lamination, wherein a curve equation of lamination temperature and time is shown as follows: T=429X2-83X+(261-271)s; coating the other surface of the polyester film substrate with an adhesive material, coating the adhesive material with a second release film, putting the film substrate in a drying oven, and drying to obtain the protective film. The protective film prepared by the method is high in tension and is capable of laminating the picture surface, the back surface and side surface of the mobile terminal at 360 degrees; the protective film is integrally molded, and is low in production cost and high in impact resistance; the mobile terminal is low in sable thickness; the preparation method is simple and can be used for effectively solving the problem that the protective film is not liable to coil because the material is softened during processing at a high temperature.

Description

technical field [0001] The invention relates to the technical field of optical films, in particular to a preparation method and application of a protective film that can fully adhere to a mobile terminal. Background technique [0002] When using electronic products, it is often easy to scratch or even break the screen or casing for various reasons. Currently commonly used electronic product protection methods are mainly divided into three categories: 1. Screen protective film. 2. Back shell. 3. Holster. [0003] The first type of screen protector is mainly made of PET. PET protective film is the most common protective film on the market at present. Strong, with good light transmittance. However, with the development of the electronics industry, the new generation of I Phones and smart phones such as Samsung, for better visual experience of the screen. Both the edge and the screen glass are designed to be curved in order to adapt to this curved edge, and the corners are ...
