The present invention provides a self-healing anti-pollution flashover coating and a preparation method and application thereof. The self-healing anti-pollution flashover coating comprises a combination of diamine-containing polydimethylsilane, a dinitrile monomer and a lubricant; Add diamine-containing polydimethylsilane as the base molecule, and add dinitrile monomers together, so that the two react to obtain a polymer containing hydrogen bond sites, which can form both intermolecular chains and intrachains. hydrogen bond, so that after the coating formed by the self-healing anti-pollution flashover coating is damaged, the molecular chain of the coating at the damaged position can move and re-form new hydrogen bonds, thereby repairing the damage; The coating can prevent the adhesion of pollutants and water droplets, and finally an anti-pollution flashover coating with high coating stability and self-healing performance is obtained. |
