| Abstract: | A stable organic-inorganic composite binder with high SiO2/K2O molar ratio potassium silicate was prepared by mixing silica sol with potassium hydroxide and silicone-acrylate emulsion, and then the waterborne inorganic zinc-rich coatings was obtained by the modified potassium silicate solution mixing flake zinc powder with the mass ratio of 1 ： 2. The influences of SiOdK20 molar ratio, solid content, reaction time, silicone-acrylate emulsion amount on the storage stability of potassium silicate solution and coatings performance were discussed. The optimum technical condition of coatings were determined by using orthogonal experiment method. The prepared waterborne inorganic zinc-rich coatings was a kind of economical and practical green coatings. |
