Embodiment 1

[0024] The specific preparation process and steps of this embodiment are as follows:

[0025] Pump 40kg of room temperature vulcanized silicone rubber and 60kg of toluene into a multifunctional mixer and mix them at a speed of about 200rpm. While stirring, add 5kg of silicon oxide and 0.3kg of sodium laurate. After the addition, stir for 50 minutes at a speed of 250rpm. Then add 0.1 kg of triethylhexyl phosphoric acid, 0.1 kg of γ-aminopropyltriethoxysilane and 0.1 kg of monobutyl tin oxide to the above mixed solution, and stir thoroughly for 150 minutes to obtain an antifouling flashover silicone coating.

Embodiment 2

[0027] The specific preparation process and steps of this embodiment are as follows:

[0028] Pump 35kg of room temperature vulcanized silicone rubber and 75kg of xylene into a multifunctional mixer and mix them at a speed of about 200rpm. While stirring, add 8kg of barium sulfate and 0.5kg of sodium laurate. After the addition, stir for 40 minutes at a speed of 250rpm. Then add 0.2 kg of sodium lauryl sulfate, 0.1 kg of γ-methacryloxypropyl trimethoxysilane and 0.05 kg of dibutyl tin dichloride to the above mixed solution, and fully stir for 180 minutes to obtain Dirt flash silicone coating.

Abstract

The invention belongs to the modified macromolecule coating technology and relates to an anti-pollution flashover organosilicon coating and a preparation method thereof. The anti-pollution flashover organosilicon coating has the starting material formulation as follows based on parts by weight: 1-50 parts of room temperature vulcanized silicone rubbers, 50-90 parts of organic solvent, 1-10 parts of fillers, 1-10 parts of organic surface treatment agents, 0.01-1 part of dispersant, 0.01-1 part of coupling agent and 0.01-1 part of organic tin catalyst. The anti-pollution flashover organosilicon coating is dry and exquisite in surface after being cured, has good self-cleaning as floating ash on the surface can be blown and washed by wind and rain and is really free of cleaning; besides, the coating has good hydrophobicity, ageing resistance and mechanical property as well as excellent high and low temperature resistance, weatherability, ozone resistance, radiation resistance and electric arc and electrical insulation.

Description

technical field [0001] The invention belongs to the technology of modified polymer coatings, and relates to an antifouling flashover organic silicon coating and a preparation method thereof. Background technique [0002] Pollution flashover is due to the fact that the surface of the insulating material of the power equipment is polluted by solid, liquid and gas conductors to form a dirty layer, which is wetted by fog and rain, resulting in partial discharge and increased leakage current. When the degree of wetting increases and the magnitude of the leakage current increases, the partial discharge arc increases, and the arc length reaches a critical value, and flashover occurs on the surface of the insulator. The previous anti-fouling flashover measures were manual cleaning, replacement of large creepage distance porcelain bottles, installation of sheds, and replacement of anti-fouling insulators. These measures were inconvenient to implement and had limited anti-fouling flas...
