The invention belongs to the technical field of superhydrophobic material preparation, and particularly relates to a method for converting hydrophilic sand into super-hydrophobic sand. The method mainly comprises the following steps: carrying out the structured processing and the low surface energy substance modification of sand surfaces. The water contact angle of the prepared super-hydrophobic sand is greater than 150 degrees, and water can freely roll on the surface of the sand without permeating. In addition, the super-hydrophobic sand exhibits extremely good thermostability, and still has good hydrophobicity at a temperature of 400DEG C. Meanwhile, the super-hydrophobic sand can be used for realizing the storage and the transportation of water, and has a good drag reduction effect. The preparation method disclosed by the invention has the advantages of simple technology, abundant raw materials, no toxin, environment protection, low cost and high thermostability, is suitable for large-area preparation and application, can be applied to the surface of a building to realize a super-hydrophobic wall, and also can be applied to the storage and the transportation of desert water so as to realize the irrigation and transportation engineering of the water in a desert.
