Abstract

Belonging to the technical field of high polymer materials, the invention in particular relates to an antistatic release film. The antistatic release film includes a polyester film, an antistatic layer on single side or double sides of the polyester film, and a release layer on the antistatic layer. The anti-static release film comprises the following components by weight: 30-60 parts of polyphenylene ethylene, 80-100 parts of adhesive resin, and 5-15 parts of an anti-adhesion agent. Compared with the prior art, according to the technical scheme provided by the invention, the antistatic layer has stable processing technology, excellent transparency and good adhesion, and the surface resistance is less than 108 omega cm.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antistatic release film. Background technique [0002] From various electronic and electrical equipment, information and communication fields to ordinary daily necessities, the application of release film is growing rapidly. The release film with high polymer film such as PP and PET as the support body is stable in size, easy to die-cut, It is widely used due to the advantages of less pollution. Especially in the processing and manufacturing of flat panel display devices, the antistatic property of the release film is required to be higher. [0003] At present, most of the protective films used in the market are made of PET substrates, and the resistivity of PET is as high as 10. 10 ~10 20 Ωcm, it is very easy to accumulate static electricity, so it is especially easy to absorb dust and impurities during production and use, which affects the performanc...
