Inorganic filler dispersion, superhydrophobic insulating and wear-resistant coating and preparation method thereof

The disclosure relates to the technical field of inorganic filler and superhydrophobic coating, and in particular, to an inorganic filler dispersion, a superhydrophobic insulating and wear-resistant coating and preparation methods thereof. The inorganic filler dispersion is formed by a primary modification of the micro-nano-meter sized inorganic filler composed of a mixture of a nanometer sized inorganic filler and a submicron-meter sized inorganic filler with a hydrophobic silane coupling agent, and a secondary modification of the primary modified micro-nano-meter sized inorganic filler in an organic solvent with a hydrophobic hydroxy-terminated blocking agent and a catalyst. The inorganic filler dispersion and the hydroxyl-terminated polydimethylsiloxane and other components are ground to obtain a pre-coating mixture, which can be used as reinforcing component and mixed evenly with the latent curing agent and the solvent to obtain a one-component superhydrophobic insulating and wear-resistant coating.
