The invention belongs to the technical field of chemical materials and discloses an azide-group-containing super-hydrophobic anticorrosion material preparation method. The super-hydrophobic anticorrosion material preparation method includes: adding, by mass, an initiator, 2-5 parts of a catalyst, 20-100 parts of an azide monomer, 60-200 parts of a fluorine-containing monomer, 3-5 parts of an auxiliary catalyst and 1-3 parts of nano silicon dioxide into a reactor, wherein the mass percent of the initiator accounts for 0.3-1% of the total mass percent of the raw materials; vacuumizing, and stirring for 10h under a blue light; pouring reaction liquid into normal hexane to obtain separated solid, dissolving the solid into a solvent to prepare a membrane, and curing for 10min under a photo-curing light to obtain a modified material which has advantages of super-hydrophobicity, corrosion resistance and the like.
