Problems solved by technology

Water-based inorganic zinc-rich paint has the advantages of no odor, non-flammable, non-explosive, and no environmental pollution due to its absence of organic solvents. However, due to less solvent and low wettability, the adhesion is not as good as the corresponding solvent-based paint, and zinc powder In the coating, due to the poor wettability of zinc powder, zinc powder is easy to settle, which affects product quality

Abstract

The invention relates to an anti-corrosive paint added with a benzene sulfonic acid / barium stearate stabilizing agent and a technology of the anti-corrosive paint. The anti-corrosive paint is prepared from 20-30% of sodium silicate, 45-60% of superfine zinc powder, 10-20% of silicon-acrylate emulsion, 3-5% of a titanate coupling agent, 3-4% of a MgCl2 aqueous solution, 2-3% of sodium dodecylbenzene sulfonate and 2-3% of barium stearate. The stability of the paint is improved by adding sodium dodecylbenzene sulfonate and barium stearate.

Description

Technical field [0001] The invention relates to an anticorrosive paint and a preparation process thereof, in particular to an anticorrosive paint added with sodium dodecylbenzene sulfonate and barium stearate stabilizer and a preparation process thereof, belonging to the field of paint synthesis. Background technique [0002] With the development of the steel anti-corrosion industry, more and more anti-corrosion paint products appear, among which zinc-rich anti-corrosion paint has also attracted more and more attention. Zinc-rich paint contains a lot of zinc powder. The zinc particles are in close contact with the surface of the steel. The potential of zinc is more negative than that of iron. Therefore, in the electrolyte solution, zinc atoms easily lose electrons and become anodes, while iron is the cathode. . In the anode zone, zinc is corroded due to the loss of electrons, and electrons are continuously obtained on the surface of the steel in the cathode zone, thereby being p...
