Abstract

The invention discloses a mobile phone body composite film. The mobile phone body composite film sequentially comprises a glass substrate, a first Cr layer, a TiO2 layer, a second Cr layer and a SiO2layer, wherein the glass substrate, the first Cr layer, the TiO2 layer, the second Cr layer and the SiO2 layer from bottom to top, and the first Cr layer, the TiO2 layer, the second Cr layer and the SiO2 layer are sequentially composited on the glass substrate through an electron beam evaporation coating method in a stagger manner. The film layers of the mobile phone body composite film are good in adhesive force when adhering to the substrate, and the adhesive force of each layer is 4B; the mobile phone body composite film is good in surface hardness, and the surface hardness ranges from 2H to 3H, and color is not prone to fading; and the mobile phone body composite film can be applied to a mobile phone rear cover, a tablet computer rear cover, a video player rear cover, a television body, an intelligent watch rear cover and the like. The invention further provides a preparation method of the mobile phone body composite film.

Description

technical field [0001] The invention relates to the technical field of film materials, in particular to a fuselage composite film and its preparation method and application. Background technique [0002] According to statistics from the China Academy of Information and Communications Technology, in 2016, China's mobile phone market shipments reached 560 million units, an increase of 8% year-on-year; among them, domestic mobile phone brand shipments reached 498 million units, accounting for 88.9% of the overall shipments ; In 2016, the total number of new models launched in the Chinese market reached 1,446, of which 1,382 were domestic models. [0003] Due to the high degree of unification of upstream parts manufacturers of mobile phones, the manufacturers supplying mobile phone parts are over-concentrated, which also leads to the serious homogenization of mobile phones. The body of a mobile phone is a carrier that integrates a sense of technology, fashion and quality. Many ...
