Abstract

The invention relates to an antistatic protective film. The antistatic protective film comprises a polyester film and antistatic coating which coats the polyester film, wherein the antistatic coatingcomprises the following components in parts by weight: 30-60 parts of acrylate resin, 1-5 parts of an antistatic agent, 0.3-3.0 parts of a curing agent, 1-2 parts of a leveling agent and 100-150 partsof a solvent. An organosiloxane monomer and a fluorine-containing acrylic monomer are directly introduced into a main chain, silicon-oxygen chain segments are formed during polymerization, and fluorine-containing chain segments can form shielding protection for the main chain and internal molecules, so that the stability of polymer molecules is improved; the cohesive force of the polymer molecules is increased after crosslinking of the acrylate resin, and the three-dimensional network structure of the antistatic coating is compact and water molecules difficultly penetrate therein, so that theweather resistance of the antistatic coating is improved; after the antistatic protective film provided by the invention is placed for 500 hours under high-temperature, constant-temperature and constant-humidity conditions, the antistatic coating can still maintain a good antistatic property.

Description

technical field [0001] The invention relates to an antistatic protective film and a preparation method thereof, belonging to the technical field of thin films. Background technique [0002] When producing optoelectronic display products such as polarizers, phase difference plates, transparent conductive films, liquid crystal displays, and touch panels, an antistatic protective film will be covered on the outermost layer, and the appearance of the optoelectronic display products will be inspected. In order to prevent the surface of the protective film from absorbing impurities due to static electricity and affect the appearance judgment of the photoelectric display product, the resistance of the protective film is generally controlled at 10 10 Ω or less. During the production, storage, transportation and use of the antistatic protective film, the antistatic coating is affected by changes in ambient temperature and humidity, resulting in an increase in surface resistance and ...
