Abstract

The application provides an anti-pollution flashover coating for preventing moss on the surface of an insulator. The anti-pollution flashover coating is prepared from the following raw materials: fluorocarbon resin, an organic solvent, g-C3N4, a flame retardant, an antifoaming agent, a leveling agent and a closed isocyanate curing agent. The anti-pollution flashover coating has the advantages thatthe anti-pollution flashover performance is improved; the graphite-like phase carbon nitride absorbs sunlight to generate ion free radicals with strong oxidizing property; the ion free radicals withstrong oxidizing property can be used for inactivating algae, thereby effectively killing moss and inhibiting the growth of the moss; and problems of toxicity, harm to the environment, poor heat resistance, poor ultraviolet resistance and the like of a moss-preventing and algae-resistant agent of a moss-preventing and anti-pollution flashover coating in the prior art are solved. The invention further provides a preparation method of the anti-pollution flashover coating for preventing moss on the surface of the insulator.

Description

technical field [0001] The invention relates to the technical field of anti-pollution flashover coatings for power systems, in particular to an anti-pollution flashover coating used for preventing moss on the surface of insulators and a preparation method thereof. Background technique [0002] With the increasing air pollution, power grid equipment is more and more prone to pollution flashover accidents, causing large-scale power outages and affecting the safe and stable operation of the power grid. The most important factor causing pollution flashover of power grid equipment is that the surface of the insulator is dirty, such as smoke, sand, salt, sea water, rain, etc., and there will be a large area of ​​moss in humid places. It will absorb moisture and inorganic salts in the air, and form a conductive layer on the surface of the insulator, which is prone to flashover under the action of an electric field. [0003] In my country's Sichuan and other warm and humid areas, i...
