Problems solved by technology

However, most of the antistatic agents or antistatic emulsions on the market have single functions, only have antistatic properties, and are suitable for the preparation of antistatic films. Then carry out release treatment, for example, silicon coating method can be used for release treatment. However, most antistatic agents or antistatic emulsions on the market are not suitable for obtaining release function by silicon coating due to their own components and performance reasons, and During the release treatment, the antistatic substance will easily lead to the weakening or even failure of the catalytic activity of the catalytic system, so it is necessary to increase the amount of catalyst added in order to solidify and form a film
In addition to increasing the cost, it will also cause the peeling force of the later release film to be unstable during storage, and even affect the stability of the antistatic performance, resulting in the failure of the antistatic performance

Abstract

The invention relates to the technical field of antistatic emulsion, and discloses a silicon paintable antistatic emulsion with good stability and a preparation method thereof. The silicon paintable antistatic emulsion comprises following components in parts by weight: 5 to 20 parts of a linear silane coupling agent containing an epoxy group, 0.05 to 1 part of phenyl hydroxyl net like silicon resin, 5 to 50 parts of conductive polymer (polythiophene), 0.5 to 20 parts of a water solution of single-walled carbon nanotubes, 1 to 5 parts of a surfactant, and 30 to 55 parts of water. After the silicon paintable antistatic emulsion is painted on a film, the prepared antistatic film has a good and stable antistatic performance, and then silicon is painted on the antistatic film to prepare an antistatic release film, which has a good antistatic performance and also has a release function.

Description

technical field [0001] The invention relates to the technical field of antistatic liquid, and more specifically, relates to a silicon-coatable antistatic emulsion with good stability and a preparation method thereof. Background technique [0002] During the handling or use of glass, high-grade plates, electronic products and other products, the surface is prone to contact pollution or scratches, so a protective film is used to cover the surface to avoid pollution or damage. Generally, plastic films are used, but plastic films The dielectric constant is small, it is a non-conductor, and its insulation performance is high, so it will generate static electricity. However, the accumulation of static electricity on the surface of the plastic film can easily cause the surface to absorb dust, even cause discharge, and cause a fire. Therefore, in order to avoid the accumulation of static electricity on the surface of the plastic film, the plastic film is usually treated with antista...
