Abstract

The present invention relates to the technical field of anti-corrosion coatings, in particular to a hydrophobic anti-corrosion coating and a preparation method thereof, wherein the hydrophobic anti-corrosion coating comprises component A and component B; the component A comprises a mixed resin, Modified zinc oxide, filler, dispersant, coupling agent, thixotropic agent, defoamer, solvent; the B component includes the following preparation raw materials: ester cyclic amine curing agent. The hydrophobic anti-corrosion paint provided by the invention has strong hydrophobicity, effectively blocks corrosive media, inhibits the penetration of corrosive ions, and has outstanding anti-corrosion effect. And in the high salt spray and high humidity environment, the hydrophobic surface of the paint film can greatly reduce the permeability of water vapor to the paint film. In this corrosive environment, it has extremely excellent corrosion resistance. The production process of the paint is simple and easy to process. Low cost, easy large-scale commercial production.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a hydrophobic anti-corrosion coating and a preparation method thereof. Background technique [0002] Metal corrosion has caused huge losses to science and technology and economic construction. Coating anti-corrosion coatings on the surface of metal substrates is one of the most effective means for metal corrosion protection and prolonging the service life of metal materials. [0003] In the marine environment where rain and fog occur frequently and corrosive gases exist, the inorganic salt contained in the dust deposited on the surface of the coating dissolves and also forms a salt solution in the ponding water on the surface of the coating. Driven by osmotic pressure, the corrosive The liquid is easy to accelerate the penetration into the coating, which quickly reduces the service life of the coating and cannot meet the actual anti-corrosion requirements. Theref...
