Abstract

Disclosed is a manufacturing process for an antistatic hard coating plastic film, comprising a first step of coating an antistatic hard coating onto the surface of a plastic film substrate and a second step of irradiating the antistatic hard coating with ultraviolet rays so as to react organosilicon with multifunctional acrylate monomers under the condition of an initiator. The antistatic hard coating plastic film provided in the invention has not only excellent antistatic performance, but also good sharpness and scratch resistance. Therefore, such antistatic hard coating plastic films can be used in liquid crystal display devices or be used as films for the protection of various image display devices.

Description

technical field [0001] The invention relates to a method for manufacturing an antistatic hard-coated plastic film, in particular to a method for endowing the film with antistatic and hard properties by a coating method. Background technique [0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, etc., and other resins, used for packaging, and as a coating layer. Plastic film is a macromolecular structure formed by polymerization and cross-linking of compounds, so it has a certain strength, and is an indispensable material with many types of products, easy processing, and abundant raw materials. [0003] However, the current plastic film has a small dielectric constant, generally belongs to non-conductor, and has high insulation performance. Therefore, the generation of static electricity cannot be avoided. Due to the accumulation of electrostatic charge on the surface of the plastic film, it is easy to cause the surface to absor...
