| titleOfInvention | Modified anticorrosive hydrotalcite, water-based intelligent anticorrosive paint, preparation method and coating |
| abstract | The invention discloses modified anticorrosive hydrotalcite, a water-based intelligent anticorrosive coating, a preparation method and a coating, wherein the preparation method of the modified anticorrosive hydrotalcite comprises the following steps: dripping a mixed solution of a metal nitrate solution, sodium hydroxide and sodium tripolyphosphate into deionized water, stirring and centrifuging to obtain anticorrosive hydrotalcite; and adding the anticorrosive hydrotalcite and dopamine into a buffer solution, stirring and centrifuging to obtain the modified anticorrosive hydrotalcite. According to the invention, the corrosion resistance is improved by utilizing the capability of the tripolyphosphate ions to passivate metal to form a protective film and the lamellar blocking effect of the hydrotalcite, the coating made of the modified corrosion-resistant hydrotalcite is coated on the surface of steel, and when the steel is corroded to generate metal cations, the catechol group on the dopamine and the metal cations can form a cross-linked network structure, so that the coating is adsorbed on the surface of a steel matrix, and the effects of automatic protection and intelligent corrosion prevention are achieved. |
