Secondary repair polyaniline-based composite anticorrosive paint as well as preparation method and application thereof

The invention discloses a secondary repair polyaniline-based composite anticorrosive paint, which comprises a component 1 and a component 2, the component 1 comprises the following components according to the total mass of the component 1: 30.0-80.0 wt% of resin, 0.01-10.0 wt% of a polyaniline-based composite material, 0.01-10.0 wt% of an aniline monomer, 0.01-5.0 wt% of titanium dioxide, 0.01-5.0 wt% of benzoin and derivatives, 0.1-1.0 wt% of a paint additive, and 1-20.0 wt% of a solvent, and the component 2 comprises a resin curing agent. Compared with the prior art, in the curing process of the coating of the polyaniline-based composite anticorrosive paint provided by the invention, aniline monomers can permeate into gaps of polyaniline molecules to absorb light energy, so that the corrosion resistance of the original polyaniline-based composite coating can be obviously improved; therefore, the technical problem of poor anti-corrosion effect caused by the fact that more corrosive media enter gaps between t
