Polyaniline conductive electrostatic paint with lasting conductivity and preparation method thereof

The invention discloses polyaniline conductive electrostatic paint with lasting conductivity and a preparation method thereof, belongs to the paint filed. The polyaniline conductive electrostatic paint comprises a component A and a component B, wherein the component A comprises the following components in percentage by mass of 10-28% of bisphenol A epoxy resin, 0.1-0.5% of dispersing agent, 0.1-0.5% of antifoaming agent, 5-20% of solvent, 10-20% of titanium dioxide, 5-35% of talcum powder, 5-30% of wollastonite in powder, 0.5-2% of gaseous phase silicon dioxide and 5-20% of conductive static polyaniline; the component B comprises 10-33% of curing agent in percentage by mass. The polyaniline conductive electrostatic paint with lasting conductivity disclosed by the invention not only guarantees corrosion resistance of a coating, but also keeps lasting and stable conductive performance of the coating; the coating surface resistivity is permanently controlled to 109 ohm magnitude order which satisfies 108-1011 ohm of GB13348-2009 Liquid Petroleum Product electrostatic Safety Regulations; and the adopted dispersing agent is copolymer liquor containing acid groups, is light yellow liquid, aromatic in smell, beneficial to lowering product viscosity and improving leveling property, beneficial to increasing content of pigment, and beneficial to pigment deflocculation by virtue of steric hindrance effect.
