Abstract: The present invention discloses a preparation method of a cardanol-modified polyamine curing agent with high corrosion resistance. The method includes the following steps: subjecting cardanol, paraformaldehyde and an amine compound to Mannich reaction, after the Mannich reaction, adding a water-soluble initiator for polymerization reaction, then evaporating water and excessive amine compound under reduced pressure after the polymerization reaction, thus obtaining a cardanol-modified polyamine curing agent. The coating obtained by curing the curing agent with an epoxy resin has greatly improved chemical resistance and corrosion resistance, indicating that the use of the water-soluble initiator in this present invention enables olefins to be polymerized very well, and molecules are reinforced obviously after polymerization, thereby greatly improving the chemical resistance and corrosion resistance.
