Abstract
The present invention provides a super-hydrophobic anti-pollution flashover coating with hydrophobicity transference, which is prepared from the following raw materials: a silicone resin, an organic solvent, silicon oxide, a flame retardant, a cross-linking agent, a coupling agent, a dispersing agent, a defoaming agent, a leveling agent, and a silicone resin curing agent. The present invention also provides a preparation method of the super-hydrophobic anti-pollution flashover coating with hydrophobicity transference. The anti-pollution flashover coating provided by the present invention has both super-hydrophobicity and hydrophobicity transference, which improves the hydrophobicity of a surface of an anti-pollution flashover coating layer, ensures the long-term effectiveness of an anti-pollution flashover coating layer, and prolongs a service life of an anti-pollution flashover coating layer, thereby solving the problem that existing anti-pollution flashover coatings have low hydrophobicity and are prone to contaminant accumulation on the surface and reducing the occurrence probability of pollution flashover accidents.
