Abstract

The invention discloses an asphalt-modified epoxy zinc phosphate heavy-duty anti-corrosion primer and a preparation method thereof. The primer comprises the following components: A component: epoxy resin A, epoxy resin B, zinc phosphate, coal tar Asphalt, modified resin, red iron oxide, precipitated barium sulfate, sericite, composite phosphorus titanium powder, anti-settling slurry, defoamer, dispersant, first mixed solvent; component B: cardanol modified polyamide resin, Salt spray resistance additive, second mixed solvent. The preparation method is to prepare component A and component B respectively, and then mix component A and component B during use. The primer of the invention has good drying performance, adhesion, salt spray resistance and chemical resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an asphalt-modified epoxy zinc phosphate heavy-duty anti-corrosion primer and a preparation method thereof. Background technique [0002] The zinc phosphates that appear on the market are all made of epoxy resin or modified resin combined with zinc phosphate. For the environment of strong acid and strong alkali, it is difficult for epoxy resin to meet its performance requirements, such as oil pipelines, oil equipment, oil storage tanks Wait. Patent CN 102898928 A discloses a moisture-cured epoxy zinc phosphate primer with rust, which can be continuously soaked in 5% sulfuric acid and 5% sodium hydroxide for 240 hours at room temperature without foaming or falling off, and is resistant to salt spray The performance can reach 1000 hours without foaming or falling off.
