The invention discloses a preparation method of a terpolymer-doped polyaniline super-hydrophobic composite anti-corrosion coating. Firstly, the solution polymerization method is used to stir the hydrophilic vinyl monomer, fluorine-containing acrylate monomer and oil-soluble initiator in a solvent evenly and react for a period of time, and then add functional acrylic monomer or long-chain acrylate. The monomer is used as the third monomer to continue to react for a period of time to obtain the fluorine-containing terpolymer surfactant. Then, the fluorine-containing terpolymer surfactant, aniline monomer and oxidant are uniformly mixed and reacted for a period of time to obtain superhydrophobic polyaniline. Finally, the prepared super-hydrophobic polyaniline is uniformly dispersed in the resin matrix to obtain a polyaniline super-hydrophobic composite anti-corrosion coating with excellent anti-corrosion properties. The invention solves the problems of poor water resistance and anti-corrosion performance of the resin matrix itself, and can be used as anti-corrosion paint to greatly improve the long-term anti-corrosion performance of metals. |
