Abstract
The application provides a super-hydrophobic anti-pollution flashover coating with hydrophobic mobility. The super-hydrophobic anti-pollution flashover coating is prepared from the following raw materials: organic silicon resin, an organic solvent, silicon oxide, a flame retardant, a cross-linking agent, a coupling agent, a dispersing agent, an antifoaming agent, a leveling agent and an organic silicon resin curing agent. The invention also provides a preparation method of the super-hydrophobic anti-pollution flashover coating with hydrophobic mobility. The anti-pollution flashover coating provided by the invention has super-hydrophobicity and hydrophobic mobility at the same time; the surface hydrophobicity of the anti-pollution flashover coating is improved, the long-term effectiveness of the anti-pollution flashover coating is ensured, the service life of the anti-pollution flashover coating is prolonged, and the occurrence probability of pollution flashover accidents is reduced, sothat problems of low hydrophobicity and easy deposition of dirt on the surface of the existing anti-pollution flashover coating are solved, and the occurrence probability of pollution flashover accidents is reduced.
Description
technical field [0001] The invention relates to the technical field of super-hydrophobic anti-fouling flashover coatings, in particular to a super-hydrophobic anti-fouling flashover coating with hydrophobic mobility and a preparation method thereof. Background technique [0002] A super-hydrophobic surface refers to a surface with a hydrophobic angle greater than 150° and a rolling angle less than 10°. In recent years, superhydrophobic surfaces have attracted widespread attention due to their unique superhydrophobic properties and self-cleaning properties, and have shown broad application prospects in production and life. [0003] With the increasing pollution of the air environment, pollution flashover accidents of transmission lines occur frequently, which seriously threatens the safe and stable operation of the power grid. Pollution flashover accidents mainly go through the following processes: the accumulation of dirt on the surface of the external insulation equipment;...
