Abstract

The invention discloses an antistatic coating, an antistatic release film with high adhesion and stability and a preparation method of the antistatic release film. The antistatic coating is an aqueous dispersion liquid or an ethyl acetate dispersion liquid containing an antistatic material; the antistatic coating is used as an external additive or an internal additive, the prepared antistatic release film has a lasting antistatic effect, the surface resistance can reach 103 omega / sq, the adhesion is high, the release force is stable, the transparency is good, and the problems of pollution, stripping failure and the like caused by static electricity when the release film is separated from an adhesive can be reduced.

Description

technical field [0001] The invention belongs to the technical field of film materials, and relates to a release film material, in particular to an antistatic coating for improving the antistatic performance of a release film material and an antistatic coating with good stability and adhesion prepared by using the antistatic coating. The release film material and its preparation technology are used to achieve the antistatic effect when the release film is separated, and at the same time to improve the excellent adhesion effect between the cured layer and the substrate. Background technique [0002] The release film refers to a film with a separable surface. The release film is not sticky or slightly sticky when in contact with a specific material under limited conditions. The production of common release films is generally surface treatment of polyester films, including coating silicon release agents, fluorine release agents or plasma treatment. Release film materials are wid...
