Embodiment 1

[0018] Add 25g of hexafluorobutyl acrylate to the agitator, start the high-speed dispersing disc at 500rpm, then add 63g of γ-methacryloxypropyltrimethoxysilane-terminated polysiloxane resin, 10g of antistatic agent, 2g Photoinitiator 1173 / 184 (ratio 1:1) 0.2g defoamer BYK333, after all the materials are added, adjust the speed to 2500rpm, disperse at high speed for 3 hours, filter the material with a 300-mesh nylon mesh.

[0019] The release agent is coated on a 0.025 micron thick PET polyester film by a coater, cured with a 365nm ultraviolet lamp, the curing energy is 80-120mJ / cm2, and the dry film thickness after curing is about 1 micron. Perform performance tests such as anti-static, peeling force, and adhesion.

Abstract

The invention relates to an ultraviolet light solidified antistatic organosilicon separant which mainly comprises the following components by weight percent: 20-50% of vinyl organosilicon resin, 10-30% of fluorine-containing activated diluent, 5-20% of antistatic agent, 0.5-5% of photoinitiator and 0.05-1% of defoamer. The ultraviolet light solidified antistatic organosilicon separant has an antistatic property so as to reduce the product pollution caused by static when a release film is stripped out of a binder; and the separant just needs to be sprayed for one time, thereby improving production efficiency, reducing cost and lowering pollution.

Description

technical field [0001] The invention relates to a silicone release agent, in particular to an ultraviolet curable antistatic silicone release agent. Background technique [0002] With the development of LED, LCD, PC, mobile phone and other electronic industries, the demand for release film is increasing day by day, and the requirements are getting higher and higher. One of them is to require the release film to have anti-static function. Ordinary release film, because its base material is PET polyester material, is an insulator, it is easy to generate static electricity during the winding and unwinding process, and the static electricity will absorb dust and impurities in the environment, affecting the quality of post-processing, and it will lead to The electronic components in contact with them are damaged by high voltage discharge. [0003] Traditional release film production uses silicone heat-curing components for coating, and there are problems such as volatilization o...
