Abstract

The invention provides an antistatic paint, an antistatic thin film and a preparation method of the antistatic thin film. The antistatic paint comprises a hard coating paint and an antistatic agent. The hard coating paint comprises the following components by weight: 20 to 35 parts of acrylic oligomer, 5 to 10 parts of acrylic monomer, 40 to 60 parts of a solvent and 1 to 5 parts of a photoinitiator. The antistatic agent comprises the following components by weight: 0.5 to 5 parts of polyacrylic acid and 1 to 20 parts of an ionic liquid. The surface pencil hardness of the antistatic thin film formed by coating the antistatic paint provided by the invention reaches 2H, the initial surface resistivity can reach 10<8> to 10<11> ohm / sq., the surface resistivity can be still 10<10> to 10<12> ohm / sq. after the thin film is wiped by the solvent, and therefore the antistatic thin film has the characteristics of high weathering resistance, high hardness, low surface resistance and good optical effects.

Description

technical field

[0001] The present invention relates to an antistatic coating, and in particular to an antistatic coating containing ionic liquid. The antistatic film formed by the antistatic coating has the characteristics of high hardness and low surface resistance. Background technique

[0002] In recent years, with the improvement and improvement of semiconductor and optoelectronic component manufacturing technology, flat-panel displays including liquid crystal display (Liquid Crystal Display, LCD) and plasma display (Plasma Display Panel, PDP) have gradually become popular in modern families. and in the office. In order to prevent the panel surface of the flat-panel display from being scratched by external forces or from being bonded to dust in the air due to static electricity, a layer of scratch-resistant antistatic film is usually added in front of the flat-panel display. In addition, antistatic film can be applied on the surface of the display, and products that ar...
