Abstract

The present invention relates to an aqueous inorganic anti-corrosion paint manufacturing technique. The preparation ratio is as follows: 190 shares of silicic acid quaternary ammonium salt, 10 shares of pure acrylic emulsion, 750 shares of zinc powder, 25 shares of wollastonite powder and 25 shares of inorganic bentonite. The present invention has following advantages of having excellent shielding property and blocking corrosion factors to move to a substrate.

Description

technical field [0001] The invention relates to a production process of water-based inorganic anticorrosion paint. Background technique [0002] Water-based inorganic zinc-rich coatings in the prior art use potassium silicate or potassium silicate as the base material, but no matter it is sodium silicate, potassium silicate or silicate, the alkali metal ions exist in the coating film after the coating is formed. The reverse reaction leads to poor water resistance of the coating film. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defective, a kind of water-based inorganic anticorrosion coating production technology is provided. [0004] The technical solution of the present invention is: a water-based inorganic anti-corrosion coating production process, characterized in that: it is a two-component coating, wherein A component is liquid, B component is powder, and the weight ratio is 1:4, A The components are composed...
