preparation example Construction

[0033] The preparation method of the anti-pollution flashover superhydrophobic self-cleaning paint of the present invention is characterized in that the silicone glass glue, polyvinylidene fluoride powder, titanium dioxide and aluminum hydroxide are first added to an organic solvent, and fully stirred to prepare a mixed dispersion , During construction, evenly coat the dispersion on the surface of the base material to obtain an anti-pollution flashover super-hydrophobic self-cleaning coating.

[0034] The silicone glass glue used in the present invention is neutral and acid silicone glass glue. The neutral silicone glass glue has a longer curing time and has weaker bonding ability than acid silicone glass glue, so acid silicone glass glue is preferred. The amount is 5-20% of the organic solvent. If the amount of silicone glass glue is too small, it is easy to cause the dispersion to have low viscosity and uneven application, and it is not easy to adhere to the substrate; if the a...

Abstract

The invention relates to anti-fouling super-hydrophobic self-cleaning paint and a preparation method thereof. The anti-fouling super-hydrophobic self-cleaning paint is characterized by being composed of silicone glass cement, polyvinylidene fluoride powder particles, photocatalyst, arc-proof agent and organic solvent, wherein the silicone glass cement is 5-20wt% of the organic solvent, the polyvinylidene fluoride powder particles is 10-50wt% of the silicone glass cement, the photocatalyst is 10-50wt% of the silicone glass cement, and the arc-proof agent is 5-20wt% of the silicone glass cement. By adoption of the anti-fouling super-hydrophobic self-cleaning paint, a surface contact angle of a coating is larger than 150 degrees, excellent insulativity is achieved, and breakdown voltage is larger than 15kV / mm.

Description

Technical field [0001] The invention relates to an anti-pollution flashover superhydrophobic paint, in particular to an anti-pollution flashover superhydrophobic self-cleaning paint and a preparation method thereof. Background technique [0002] The outer insulating surface of power equipment will gradually accumulate dirt during operation. In the dry state, the dirt layer has a large resistance, and the leakage current flowing through the dirt layer is small, which has no significant impact on the insulation strength. However, under climatic conditions such as fog, dew, drizzle, and melting snow, the dirty layer is wetted and the electrolyte in the dirty layer is dissolved, which increases the surface conductance in the dirty layer and increases the leakage current. Due to the thermal effect of the leakage current, a dry zone appears where the current density is large. The resistance of the dirt layer in the dry zone increases sharply, causing the dry zone to withstand a higher ...
