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...
