Protective film for liquid crystal display and preparation process of protective film

Abstract

The invention discloses a protective film for liquid crystal display and a preparation process of the protective film. The protective film for liquid crystal display comprises a first ink layer, a first PET release film, a silica gel layer and the like, wherein the bottom surface of the first ink layer is connected with the top surface of the first PET release film, the bottom surface of the firstPET release film is connected with the top surface of the silica gel layer, and the bottom surface of the silica gel layer is connected with the top surface of a PU adhesive layer; the bottom surfaceof the PU adhesive layer is connected with the top surface of a PET base material, the bottom surface of the PET base material is connected with the top surface of an acrylic adhesive layer, and thebottom surface of the acrylic adhesive layer is connected with the top surface of a scratch-resistant adhesive layer; and the bottom surface of the scratch-resistant adhesive layer is connected with the top surface of a second PET release film. The protective film has reasonable design, a simple structure, excellent electric insulativity, resistance to high temperature and friction and good stability, requirements of different customers can be met, a protective film attaching procedure can be eliminated, the efficiency can be improved, and the cost is saved; and the problem that the protectivefilm falls off from the film periphery can be solved, and the protective film can be applied to high-temperature conditions, curved surface occasions and other special application fields.

Description

technical field [0001] The invention relates to a protective film and its preparation process, in particular to a liquid crystal display protective film and its preparation process. Background technique [0002] The liquid crystal display panel is located on the uppermost layer of the liquid crystal display module. In order to prevent its surface from adhering to external dust particles, or artificial wear and scratches during the process of handling, storage and stacking, etc., the existing liquid crystal display modules are all attached There are liquid crystal display module protective films made of plastic materials such as polyethylene (PE) or polyethylene terephthalate (PET). The existing protective film attachment needs to separate the protective film on the surface of the liquid crystal display panel and the protective film of the printed circuit board, and the protective film is attached by the operator with one hand. Take the tape, and fix the protective film on t...

AI Technical Summary

Problems solved by technology

The existing protective film attachment process is complicated, low in efficiency, high in cost, and the protective film is easy to fall off from the periphery of the film, and the existing protective film cannot meet the application of special occasions, such as high temperature conditions, curved surface occasions, etc.
