Abstract

The invention relates anti-static coating for a photo-curing nanometer polyaniline-epoxy acrylic resin interpenetrating network, which is prepared by interpenetrating polyaniline and an epoxy acrylic resin system under the action of an initiator and a catalytic agent. Aniline is subjected to in-situ emulsion polymerization in epoxy acrylic resin to obtain doped nanometer polyaniline particles, and a dilute monomer, a catalytic agent, an initiator, a polymerization inhibitor and fillers are further added into the doped nanometer polyaniline particles to be stirred evenly. The anti-static coating is simple in process device, convenient to operate and quick in curing speed. The anti-static coating for the photo-curing nanometer polyaniline-epoxy acrylic resin interpenetrating network has good glossiness, stable electric conduction performance, good mechanical property, ageing-resistant performance and chemical erosion resistance performance, not only can serve as the anti-static coating, but also has the price and environment-friendly advantages. Products can be used in the inner walls of oil transmission pipelines, electronic machines, electrostatic dust preventing floors, bridges, railways and other places and have wide application range and good economic and social benefits.

Description

technical field [0001] The invention relates to the field of polymer antistatic coatings in polymer materials, in particular to a light-cured nano polyaniline-epoxy acrylic resin interpenetrating network antistatic coating. Background technique [0002] Conductive coating is a functional special coating that is applied to high resistivity polymer materials to enable it to conduct current and eliminate accumulated static charges. It can be coated on the surface or inside of any shape substrate. Conductive coatings have many advantages such as convenient construction, simple equipment, low cost and wide application range, and are used in electronics, construction, aviation and military fields. Polyaniline conducts electricity because the molecular structure contains large π bonds, and π electrons move freely on the molecular chain. Polyaniline has many advantages such as good electrical conductivity, high stability in air and high thermal stability, light weight, simple synth...
