Abstract

The invention discloses a high-performance anti-electrostatic ultralight stripping PET release film. The high-performance anti-electrostatic ultralight stripping PET release film is prepared from thefollowing raw materials: 40%-50% of siloxane polymer, 30%-50% of cosolvent, 10%-25% of antistat, 3%-8% of cross-linker, 5%-15% of anchoring agent and 2%-5% of catalyst. According to the high-performance anti-electrostatic ultralight stripping PET release film provided by the invention, the siloxane polymer is adopted as a main material, the production and manufacturing cost can be reduced greatly,a surface coating is formed by adopting the antistat, cannot interact a silicon coating and is free of mobility along with temperature changes, the electric conduction performance is stable, and thus, the anti-electrostatic effect is effectively improved; and the high-performance anti-electrostatic ultralight stripping PET release film is free of harmful substances, so that the safety of use is guaranteed.

Description

technical field [0001] The invention relates to the technical field of release films, in particular to a high-performance antistatic ultralight peeling PET release film. Background technique [0002] In the current industrial production, the use of PET release film is very wide, but there are some shortcomings in the production process of the existing PET release film, not only the production process is relatively complicated, which greatly increases its manufacturing cost, but also due to the selection of There are factors of mutual interference between raw materials, which not only easily peel off and affect the service life, but also further affect the performance of the release film, resulting in poor conductivity, easy to be affected by static electricity, and contain harmful substances such as heavy metals and VOC. Less secure. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a high-pe...
