Super-hydrophobic composite ceramic coating

The invention discloses a super-hydrophobic composite ceramic coating. The super-hydrophobic composite ceramic coating comprises a component A, a component B and a component C. The component A comprises phosphoric acid, phosphate, attapulgite, natural kaolin, metakaolin and siliceous powder, with the balance being water. The component B comprises a metal oxide, a hydroxide and wollastonite, with the balance being water. The component C comprises hydrophobic nanometer silicon dioxide, attapulgite, polysiloxane and neutral silicone glass cement and with the balance being absolute ethyl alcohol. The super-hydrophobic composite ceramic coating provided by the invention can be used for forming a hydrophobic ceramic coating on metal to compensate for the defect that an inorganic ceramic coating has a hydrophilic characteristic; and the hydrophobic coating with a contact angle larger than 150 degrees and excellent performance is formed outside the ceramic coating, so corrosion of the external environment to the cera
