Abstract

The invention discloses an epoxy zinc-rich primer and a preparation method thereof. The epoxy zinc-rich primer comprises the following components in percentage by mass: component A: 10-15% of E20 epoxy resin, 0.2-0.4% of dispersant, 2-4% of barium petroleum sulfonate, 30-50% of zinc powder, 10-20% of composite iron-titanium, 5-10% of sericite, 1-1.2% of organic bentonite, and 18.25-21.6% of mixed solvent; component B: 15-30% of cardanol-modified polyamide resin, 1-2% of epoxy accelerator, and 68-84% of mixed solvent. The preparation method for the component A comprises the following steps: adopting the mixed solvent to dissolve each component respectively, then adjusting the viscosity to a desired value through the mixed solvent; the preparation method for the component B comprises the following steps: dissolving each component through the mixed solvent. During use, the volume ratio of the component A and the component B is (3-5):1.

Description
