Abstract

The invention discloses an environment-friendly composite material for a back film of a mobile phone. The material comprises a base film layer. An adhesive layer is arranged on one side of the base film layer, release paper is arranged on one side of the adhesive layer, a protecting layer is arranged in the base film layer, a decorative layer is arranged on one side of the protecting layer, and aprotecting protruding point is arranged on one side of the base film layer. By arranging the protecting layer and the protecting point, a user separates the release paper and the adhesive layer, the base film layer and a back shell of the mobile phone can be adhered through the adhesive layer, the decorative layer can increase the charm value of the base film layer, and the protecting layer is arranged to block external electromagnetic waves, so that the using effect that the mobile phone is relatively smooth is achieved. By arranging the protecting protruding point, the frictional force between the base film layer and the hand of the user can be increased, so that the user can take the mobile phone conveniently. The probability that the mobile phone falls off accidently as a result of insufficient frictional force is reduced.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to an environmentally friendly composite material used for the back film of a mobile phone. Background technique [0002] A mobile phone, also known as a mobile phone, is a mobile phone that can be held in the hand. In the early days, it was commonly known as Big Brother, and it was a portable phone terminal that could be used in a wide range. Mobile phone back film, also known as beauty film and mobile phone protective film, is a kind of cold lamination film that can be used to mount the surface of mobile phone body, screen and other tangible objects. The existing mobile phone rear film only has a protective effect and cannot meet the increasing needs of users. [0003] Therefore, it is necessary to invent an environmentally friendly composite material for the back film of a mobile phone to solve the above problems. Contents of the invention [0004] The purpose of the prese...
