High-temperature-resistant wear-resistant hydrophilic inorganic coating as well as preparation method and application thereof

The invention belongs to the technical field of functional coatings, and discloses a high-temperature-resistant and wear-resistant hydrophilic inorganic coating as well as a preparation method and application thereof. The high-temperature-resistant and wear-resistant hydrophilic inorganic coating comprises a component A, a component B and water, and the component A comprises the following components in parts by weight: 45-75 parts of silica sol, 10-20 parts of gamma-aluminum oxide, 0.5-5 parts of alpha-aluminum oxide, 1-5 parts of cobalt black, 0.1-5 parts of polyethylene glycol and 0.1-5 parts of a flatting agent; the component B comprises 20-30 parts of titanium powder, 1-2 parts of gamma-aluminum oxide, 1.2-30 parts of a carbon material and 1-5 parts of a flatting agent. The high-temperature-resistant and wear-resistant hydrophilic inorganic coating is formed through spraying, sintering at 500-600 DEG C and heat preservation. The inorganic coating has good hydrophilicity, corrosion resistance, binding forc
