The invention relates to a novel RTV slow-release type long-acting super-hydrophobic pollution-flashover-resistant coating material. According to the present invention, nanometer active metal oxides such as nanometer titanium dioxide, nanometer alumina and nanometer zinc oxide are added, and the ratio is optimized, such that the catalytic effect is improved, the improved slow-release type long-acting super-hydrophobic pollution-flashover-resistant coating material can be efficiently processed, the RTV is strengthened, and the mechanical property, the electrical property and the anti-aging property of the coating are improved; the surface structure and the characteristics of the RTV coating are improved with the nanometer powder material, such that the self-cleaning ability and the water repellency of the coating are enhanced, the coating has the good effect, and pollution flashover resistance is easily achieved; and the novel RTV slow-release type long-acting super-hydrophobic pollution-flashover-resistant coating material can provide important practical significance in the anti-fouling work of super high voltage and ultra high voltage power network lines, can save a lot of construction funds and operation and maintenance costs, and can create good social and economic benefits.

Description

technical field [0001] The invention belongs to the field of paint processing, and relates to an antifouling flashover paint, in particular to a slow-release long-acting super-hydrophobic antifouling flashover paint. Background technique [0002] With the rapid development of industrial and agricultural production, the air pollution is becoming more and more serious, the pollution is aggravated, the environment is deteriorated, the voltage is increased, the network is expanded, and the number of AC and DC interconnections is increasing, and the pollution flashover accidents of the power system continue to occur. Pollution flashover accidents involve a wide range, and the power outage lasts for a long time, which seriously threatens the safe operation of power transmission and transformation equipment and brings great economic losses to the national economy. Every winter, thousands of pollution flashover trips occur on the national power grid, sometimes almost causing the pro...
