The invention relates to a method for preparing a micro-groove anisotropy super-hydrophobic surface material through a mechanical engraving method. The method sequentially comprises the following steps that 1, preparation is made before mechanical engraving; 2, a micro-groove structure is mechanically engraved on a copper-clad plate base material; 3, the micro-groove copper-clad plate is cleaned;4, the surface micro-structure of the micro-groove copper-clad plate is chemically etched and prepared; and 5, the super-hydrophobic surface material with the anisotropy is prepared for surface decorating. According to the method, an automatic numerical control engraving machine is utilized for engraving a micro-groove matrix graph array on the surface of the copper-clad plate, after the copper-clad plate is cleaned, a ferric oxide hydrochloric acid solution is adopted for etching the surface micro-structure, then a lauric acid ethanol solution is adopted for carrying out surface decorating, the micro-groove anisotrop
