Abstract

The invention belongs to the technical field of coatings, and particularly relates to a high-self-cleaning super-smooth anti-pollution flashover coating and a preparation method thereof. The high- self-cleaning type super-smooth anti-pollution flashover coating is characterized by being prepared from the following raw materials in percentage by mass: 4 to 12 percent of lubricating oil, 10 to 15 percent of fluorocarbon resin, 68 to 80 percent of a solvent, 1 to 6 percent of hydrophobic SiO2, 1 to 5 percent of polytetrafluoroethylene (PTFE) and 0.2 to 1.5 percent of a silane coupling agent. A coating layer formed by spraying the paint through an aerosol can has good self-cleaning property, super-smoothness, pollution flashover resistance and icing resistance; and good corrosion resistance and aging resistance are achieved.

Description

technical field

[0001] The invention belongs to the technical field of coatings, and in particular relates to a high self-cleaning super-slip antifouling flashover coating and a preparation method thereof. Background technique

[0002] Transmission line insulators are prone to pollution flashover in the presence of dirt, or ice flashover in icy environments, seriously affecting the safe operation of transmission lines, and causing serious economic losses every year due to insulator pollution flashover and ice flashover. It has brought huge troubles to the power industry. At present, room temperature vulcanized silicone rubber RTV coatings are used to coat insulators, but the anti-pollution flashover and anti-ice flashover effects of RTV are not ideal, and pollution flashover and ice flashover events still occur frequently. The cause of the flashover event is that the RTV coating is easy to accumulate dirt after long-term operation, and the dirt remains on the surface of the...
