Problems solved by technology

[0003] However, the current anti-fouling flashover technology still faces many problems. The biggest problem is that the anti-fouling flashover coating has poor adhesion and cannot play the function of anti-fouling flashover for a long time. In addition, there are poor wear resistance, The problem of poor strength also affects the long-term antifouling flashover function of the coating

Abstract

The invention provides an anti-pollution flashover coating which is prepared from the following components in parts by weight: 25-36 parts of organic silicon resin, 10-15 parts of nano silicon dioxidesol, 5-9 parts of titanium dioxide, 3-10 parts of aluminum oxide, 0.5-2 parts of hydroxyethyl cellulose, 1-3 parts of hydrophobic rock wool powder and 26-40 parts of high-molecular solvent. Accordingto the anti-pollution flashover coating provided by the invention, the adhesion property and wear resistance of the anti-pollution flashover coating can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antifouling flashover coating. Background technique [0002] Under severe weather conditions (such as: fog, dew, drizzle, etc.), flashovers will occur along the wet insulator surface, resulting in power system pollution flashover accidents. Pollution flashover threatens the safe and stable operation of the power system. If it is mild, it will affect local power supply. If it is serious, it will affect the power grid, and even cause the entire power grid to crack. The impact of pollution flashover on the power supply system has caused huge losses to the national economy. [0003] However, the current anti-fouling flashover technology still faces many problems. The biggest problem is that the anti-fouling flashover coating has poor adhesion and cannot play the function of anti-fouling flashover for a long time. In addition, there are poor wear resistance, The problem of poor ...
