Problems solved by technology

Since most of the antistatic agents or antistatic emulsions currently on the market do not have a release function, the conventional antistatic release film preparation method is to perform antistatic treatment on the film substrate, and then perform release treatment, so that it will Increase the process, resulting in a long production cycle, and in the release treatment, the antistatic substance will easily lead to the weakening or even failure of the catalytic activity of the catalytic system during the film forming process, so it is necessary to increase the amount of catalyst to solidify and form a film
The two-step method of antistatic treatment and release treatment to prepare antistatic release film not only increases the cost, but also leads to unstable peeling force of the release film during later storage, and even affects the stability of antistatic performance. lead to failure of antistatic performance

Abstract

The invention relates to the technical field of release emulsion, and discloses antistatic release emulsion with excellent stability performance and a method for preparing the antistatic release emulsion. The antistatic release emulsion with the excellent stability performance comprises, by weight, 5-20 parts of alkenyl polysiloxane, 0.5-10 parts of hydrogen-containing polysiloxane, 0.05-1 part ofphenyl hydroxyl reticular silicon resin, 0.05-5 parts of conductive polymer polythiophene, 0.05-2 parts of single-wall carbon nano-tube aqueous solution, 1-5 parts of linear silane coupling agents with epoxy groups, 1-10 parts of surfactants and 60-85 parts of water. The antistatic release emulsion and the method have the advantages that the antistatic release emulsion can be applied to thin filmbase materials, and prepared release films are excellent in stable antistatic property and stable in release property; the antistatic release emulsion is suitable for online coating, working procedures can be reduced, and the cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of release emulsions, in particular to an antistatic release 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 antistatic treatment to enhance ...
