The invention relates to a wear-resistant super-hydrophobic coating compound. The compound at least comprises the following components: i) super-hydrophobic sol having amino group, and ii) resin capable of reacting with super-hydrophobic sol or combining with super-hydrophobic sol thorough a hydrogen bond and intermolecular force. The coating compound can be used for coating on the surface of a matrix such as glass, metal, ceramic, paper and cloth by a coating, spin coating, spraying or spray coating method, and a super-hydrophobic layer is formed. The coating formed on the hard base materials such as glass and metal has excellent hydrophobicity and wear resistance; a contact angle is greater than 160 DEG, a roll angle is 1 DEG; under pressure of 100g counterweight, 240-mesh sand paper is used for grinding, grinding thickness for each time is 10 cm, the contact angle after 40 times of grinding is still greater than 157 DEG C; THE pencil hardness is 7-9 H, and the adhesive force is between grade 0 and 1.
