Abstract

The invention discloses a super-hydrophobic anticorrosive coating used for power transmission and transformation devices. The coating comprises, by weight, 10-18 parts of modified nanometer zirconium dioxide, 6-16 parts of modified nano-silica, 20-40 parts of polyurethane resin, 3-7 parts of a curing agent, 2-10 parts of a coupling agent, 0.5-1 part of a leveling agent, 0.5-1.5 parts of an antifoaming agent, 0.5-1 part of a dispersant, 0.2-0.6 parts of a drier, 0.3-1.2 parts of an antioxidant, 0.2-0.6 parts of an ultraviolet absorber, and 30-50 parts of a solvent. The static contact angle of the super-hydrophobic anticorrosive coating used for power transmission and transformation devices reaches up to 160-167 DEG, and the roll angle reaches 2-4 DEG, so the coating has excellent hydrophobic performance; and the super-hydrophobic anticorrosive coating used for power transmission and transformation devices also has the advantages of very good anticorrosive performance, environmental protection and energy saving, environment pollution reduction, and meeting of current green production principles.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a superhydrophobic anticorrosion coating for power transmission and transformation equipment and a preparation method thereof. Background technique [0002] A variety of power transmission and transformation equipment in my country's power system, such as transformers, transmission towers, and transmission lines, have been exposed to the air for a long time, resulting in the gradual accumulation of dirt on the outer insulating surface of the power transmission and transformation equipment during operation. Under climatic conditions such as snow melting and melting snow, the dirty layer is moistened and the electrolyte in the dirty layer dissolves, which increases the surface conductance and leakage current in the dirty layer, and pollution flashover accidents are prone to occur on the outer insulating surface of the equipment. At present, the common treatment method is...
