LONG-ACTING SUPER-HYDROPHOBIC COATING RESISTANT TO WATER PRESSURE IMPACT AND PREPARATION METHOD THEREFOR

摘要

A long-acting super-hydrophobic coating resistant to water pressure impact and a preparation method therefor. The long-acting super-hydrophobic coating resistant to water pressure impact comprises a conductive substrate, and further comprises the following raw materials in parts by weight: 1-10 parts of titanium source or 1-10 parts of zinc source, 40-100 parts of deionized water, 20-50 parts of hydrochloric acid or 20-40 parts of sodium hydroxide, 1-10 parts of electrolyte, 1-10 parts of low-surface-energy modifier, 10-20 parts of a high-molecular polymer, 1-5 parts of carbon nanotubes, and 70-100 parts of an organic solvent. The special organic-inorganic nano interpenetrating network structure of the long-acting super-hydrophobic coating resistant to water pressure impact greatly improves the stability of a multi-level nanostructure, so that the surface of the super-hydrophobic coating has good resistance to high pressure water impact and resistance to high pressure static water.
