Problems solved by technology

[0012] In order to overcome the defect that the overall performance of the total antistatic polyester in the prior art cannot meet the actual needs, especially the defect that the antistatic performance of the antistatic polyester is rapidly lost in a humid environment, the invention provides a water-resistant and wear-resistant antistatic Polyester, which is coated on the surface of conventional polyester sheet through a special solution containing π-conjugated conductive polymer, mixed monomer and acrylic resin. A dense antistatic protective layer is formed on the surface, which can ensure excellent antistatic performance under high temperature and high humidity or soaked in water, or after repeated friction and scratches

Abstract

The invention relates to a water-resistant wear-resistant antistatic polyester film, which is obtained by coating the surface of polyester with an antistatic material solution and then stretching and curing, wherein the antistatic material solution comprises the following raw materials: a mixed monomer, epoxy acrylic resin, a pi-conjugated conductive polymer, an alcohol-water mixed solvent, an emulsifier and an initiator, the mixed monomer comprises 2-acrylamido-2-methylpropanesulfonic acid, a hydrophobic anionic monomer, (methyl) hydroxy acrylate and polyethylene glycol diacrylate. The antistatic polyester film developed by the invention can still keep excellent antistatic performance in a high-humidity saturated environment or after multiple times of friction, and has more excellent moisture resistance and durable antistatic property.

Description

technical field [0001] The invention relates to the field of polyester films, in particular to a water-resistant surface antistatic polyester film and a preparation method thereof. Background technique [0002] Because of its stable size, good mechanical strength and optical properties, polyester film is widely used in packaging materials, optical equipment and electrical appliances. However, since polyester is a covalently bonded polymer, the density of polar groups is very low, and it is an insulating material with a high surface resistivity (usually 10 12 ~10 30 Ω·cm 2 ), it is easy to accumulate static electricity during processing or use. The accumulation of static electricity to a certain extent may lead to electrostatic dust collection, electric shock, and even fire and explosion. When used as a packaging film, insulating film or protective film, it is very easy to damage various Electronic sensitive components, instruments, etc. interfere or cause electronic produ...
