Abstract

The invention relates to an antistatic polyester film and a preparation method thereof, wherein the antistatic polyester film comprises a polyester film and an antistatic coating layer coated on the surface of the polyester film; the antistatic coating layer is composed of hybrid acrylate resin, an antistatic agent, a curing agent and a solvent; the antistatic coating layer is composed of the components in parts by weight: 30-50 parts of hybrid acrylate resin, 0.5-1 part of a leveling agent, 0.2-2.0 part of the curing agent, and 90-120 parts of the solvent. According to the invention, polythiophene conductive macromolecules are added in the polymerization process, the synergistic effect of polythiophene and modified nano inorganic particles is utilized to improve the antistatic property, and the used modified nano inorganic particles have good rigidity and hardness, are copolymerized with other acrylate monomers after being modified by a silane coupling agent and are uniformly distributed in acrylate resin. According to the hybrid acrylate resin prepared by the preparation method disclosed by the invention, coating is performed after compounding, so that the antistatic coating layer coated on the surface of the polyester film has scratch resistance, meanwhile, the antistatic performance of the film is also improved, and electrostatic adsorption of impurities can be effectivelyprevented.

Description

technical field [0001] The invention relates to the technical field of films, in particular to an antistatic polyester film. Background technique [0002] When preparing an antistatic polyester film, it is necessary to first coat one side of the polyester film with an antistatic coating to prepare an antistatic polyester film, and then coat other functional coatings on the other side, such as antistatic polyester film. The other side of the ester film was coated with acrylic pressure-sensitive adhesive to prepare a polarizer protective film. In the process of coating pressure-sensitive adhesive, due to equipment, process and other reasons, the surface of the antistatic coating is often scratched, or the surface is scratched during handling and use, which affects the quality of the product. Therefore, antistatic coatings are required to have anti-scratch properties. [0003] Chinese patent CN105482728A provides a kind of anti-scratch pre-coating film, the anti-scratch subst...
