[0018] The preparation method of this modified water-based zinc-rich paint comprises the following steps:
[0019] (1) get each raw material component by described proportioning;
[0020] (2) Add water and sodium bentonite to the mixing tank and stir evenly; then add potassium silicate and potassium methyl silicate and stir evenly; then add emulsified asphalt and stir evenly; finally add tributyl phosphate and sodium polyacrylate , and stir evenly to obtain a water-based binder base material;
[0021] (3) adding scaly zinc powder to the water-based binder base material, and stirring evenly to obtain a water-based inorganic zinc-rich coating.
[0022] The stirring time and stirring speed in the preparation process can be adjusted according to the actual situation, and the stirring is kept during the process of adding each raw material component. In the embodiment provided by the present invention: after adding water and sodium bentonite, the stirring speed is controlled to be...
