Potassium magnesium phosphate-based steel anticorrosive coating material and preparation method thereof

YANG JIANMING / LI TAO / HAN CHAO

The invention discloses a potassium magnesium phosphate-based steel anticorrosive coating material and a preparation method thereof. The potassium magnesium phosphate-based steel anticorrosive coating material is formed by mixing a magnesium potassium phosphate cementing material, a setting time regulating component, a corrosion inhibition component and a toughening component, or is prepared from the magnesium potassium phosphate cementing material, a composite retarder component, the corrosion inhibition component and the toughening component. The potassium magnesium phosphate-based steel anticorrosive coating material has excellent properties such as normal-temperature curing, rapid hardening, high strength, low shrinkage, freezing resistance, salt freezing resistance, salt erosion resistance, high temperature resistance and strong environmental adaptability, and also has excellent toughness and impact resistance.
