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
The invention belongs to the modified high-molecular coating technology, relate to a kind of anti-pollution flashover organosilicon coating and preparation method thereof.
Background technology
Pollution flashover is because the insulating material surface of power equipment is formed pollution layer by the pollution of solid, liquids and gases conducting objects, meets mist dew and rainwater and makes moist wettingly, causes shelf depreciation, and Leakage Current increases.When the wetness degree increase, when the Leakage Current amplitude increased, the shelf depreciation arc increased, and arc length reaches threshold value, and flashover can take place insulator surface.Anti-pollution flashover measure in the past is artificial cleaning, changes the large distance porcelain vase, installs full skirt additional, changes anti-pollution type insulator, and comparatively inconvenience is implemented in these measures, and anti-pollution flashover effect is limited.
The existing at present research that room temperature vulcanized silicone rubber (RTV) is used for antifouling flush paint, but because the main body of RTV antifouling flush paint is the polymer organo-silicone rubber, behind self cure or the film-forming, the sticking power between coating and the insulator is lower, coating hardness is less, easily scratches; And long-term exposure is subjected to effects such as uviolizing, electromagnetic field and dust storm in the open air, and the life-span of its anti-pollution flashover is not long.Under dirty area and bad weather condition, also may produce dried belt discharge phenomenon.In addition, the arc ablation resistance ability of coating also can influence the work-ing life of insulator.
