Camera protecting film and preparation process thereof

Abstract

The invention discloses a camera protecting film and a preparation process thereof. The camera protecting film comprises a polyethylene protecting film layer, a stickup layer A, a foam superimposed layer, a stickup layer B and a polyethylene glycol terephthalate layer from top to bottom sequentially, wherein the stickup layer A and the stickup layer B are acryl glue layers, two hollow areas in the same size are arranged on each of the polyethylene protecting film layer, the stickup layer A, the foam superimposed layer and the stickup layer B, the acryl glue layers are 0.15 mm thick, a silica gel bonding layer is 0.02 mm thick, a base material in the polyethylene protecting film layer is 0.038 mm thick, the polyethylene glycol terephthalate layer is 0.15 mm thick, and the foam superimposed layer is 0.5 mm or 1.0 mm thick. The design idea of the camera protecting film is that multiple different materials are superimposed and glued to form a whole with a certain thickness, an outwards bulging camera can be well protected when used by a user, the requirement for high efficiency is met, the production time is saved, the cost is reduced, and the benefits are maximized.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a camera protective film and a preparation process thereof. Background technique [0002] With the rapid development of the electronics industry, consumers have higher and higher requirements for the performance of electronic products, and have higher and higher requirements for appearance design, hardware design and software functions. At the same time, they have higher pursuit of cost performance of electronic products. . Especially in the mobile phone and notebook industries, ultra-thin and light-weight has been the main development direction in recent years, and the structure and function of electronic components are also developing in the direction of miniaturization and multi-function, and the requirements for mobile phone cameras are also getting higher and higher.

AI Technical Summary

Problems solved by technology

[0003] The previous camera protective films in the industry are basically attached to the camera lens, and they are all designed for flat attachment. This design cannot meet the goal of the convex camera that customers need, and customers cannot completely protect it when using it. The surrounding area of ​​the camera is good, and the camera will be scratched and dirty due to the peeling off of the protective film during the assembly process

Moreover, the thickness of the existing protective film is not enough, it is easy to cause damage to the lens, and some protective films are produced with insufficient precision, and cannot fit well when they are attached to the camera, causing the protective film to fall off
