Super-hydrophobic powder prepared from hole slag micro-powder as well as preparation method and application of super-hydrophobic powder

The invention provides super-hydrophobic powder prepared from hole slag micro-powder, and relates to the technical field of super-hydrophobic materials, and the super-hydrophobic powder comprises the following components by weight: 10-20% of hole slag micro-powder particles, 5-10% of a siloxane modifier, 5-10% of tetraethoxysilane and 70-80% of absolute ethyl alcohol. The super-hydrophobic material has an excellent hydrophobic effect and can be used for preparing a self-cleaning coating, the hydrophobic angle of the obtained coating can reach 156 +/-3 degrees, the self-cleaning effect is good, the existing hole slag resources are effectively utilized, the problems that the existing hole slag is difficult to utilize, the environment is harmed and the like are solved, and the raw material cost of the super-hydrophobic self-cleaning coating is reduced. The invention also provides a self-cleaning coating prepared from the super-hydrophobic powder and a preparation method, the self-cleaning coating can be used as
