PE (polyethylene) electrostatic protective film as well as preparation method and coating equipment thereof

Abstract

The invention discloses a PE electrostatic protective film and a preparation method and coating equipment thereof. The PE electrostatic protective film comprises a PE base film layer, an electrostatic liquid layer, a high temperature resistant layer and an adhesive layer, the electrostatic liquid layer is arranged on the PE base film layer, the high temperature resistant layer is arranged on the electrostatic liquid layer, the adhesive layer is arranged on the top of the high temperature resistant layer, and the adhesive layer is arranged on the top of the high temperature resistant layer. The thicknesses of the PE base film layer, the electrostatic liquid layer, the high-temperature-resistant layer and the adhesive layer are 50-90 microns, 2.2-3.5 microns, 2.6-4.3 microns and 4-6 microns respectively; impedance of the PE protective film ranges from 107 ohm/cm < 2 > to 1011 ohm/cm < 2 >, antistatic performance is remarkably improved, nano conductive particles and conductive liquid can be effectively dispersed by the vinyl resin type amide polymer, system distribution is uniform, conductivity values of prepared products are consistent, meanwhile, the PE protective film has better high-temperature-resistant characteristic by designing the high-temperature-resistant layer, the use requirements are met; and in addition, the equipment can be conveniently adjusted according to the parameters.

Description

Problems solved by technology

[0003] In the existing production activities, PE protective film is usually used to protect the surface of the product. However, the current PE protective film has poor antistatic performance and high temperature resistance, and it is difficult to meet the requirements of use. At the same time, the electrostatic liquid layer coating machine does not Easy to adjust according to
