Embodiment 1
[0033] Mix 30 parts of block resin (produced by Shenzhen Taike Technology Co., Ltd., a typical resin with hydrophobic migration properties) and 70 parts of silicone acrylic resin, add an appropriate amount of butyl acetate to adjust the concentration of the mixture, Slowly stir and blend in a closed container for 5 hours, take out the product, and add 0.5 part of leveling agent to obtain a room temperature type anti-pollution flashover hard coating for electric power external insulation.
[0034] When in use, take out 100 parts of antifouling flash hard paint, add 0.1 part of zirconium isooctanoate, 0.1 part of dibutyltin dilaurate, 1 part of ethyl orthosilicate, stir well, adjust the viscosity with butyl acetate, Then it is used for spraying or brushing on the lower surface of the insulating part of the insulator, and the thickness of the coating is 0.01mm.
[0035] Such as figure 1 As shown, it is a cross-sectional view of the right half of the outer surface of an axisymmet...
Embodiment 2
[0037] Mix 50 parts of block resin (Shenzhen Taike Technology Co., Ltd.) with 50 parts of silicone acrylic resin, add an appropriate amount of solvent to adjust the concentration of the mixture, stir and blend slowly in a closed container at room temperature for 7 hours, take out the product, add leveling 2 parts to obtain room temperature type electric power external insulation anti-pollution flashover hard coating.
[0038] When using, take out 100 parts of antifouling flash hard paint, add 1 part of zirconium isooctanoate, 1 part of dibutyltin dilaurate, N-(ethylaminoethyl)-3-aminopropylmethyl dimethoxy 1 part of silane, 7 parts of tetraethyl orthosilicate, stir evenly, adjust the viscosity with butyl acetate, and then spray or brush on the lower surface of the insulating part of the insulator, and the coating thickness is 0.02mm.
Embodiment 3
[0040] Mix 70 parts of block resin (Shenzhen Taike Technology Co., Ltd.) with 30 parts of silicone acrylic resin, add an appropriate amount of solvent to adjust the concentration of the mixture, stir and blend slowly in a closed container at room temperature for 7 hours, take out the product, add leveling The antifouling flashover hard coating for room temperature electric power external insulation can be obtained by adding 5 parts of the agent.
[0041] When using, take out 100 parts of antifouling flash hard paint, add 2 parts of zirconium isooctanoate, 2 parts of dibutyltin dilaurate, N-(ethylaminoethyl)-3-aminopropylmethyl dimethoxy 2 parts of silane and 10 parts of tetraethyl orthosilicate are stirred evenly, and the viscosity is adjusted with butyl acetate, and then sprayed or brushed on the lower surface of the insulating part of the insulator, and the coating thickness is 0.5mm.
