The invention relates to the field of preparation of super-hydrophobic coatings, in particular to a preparation method of a super-hydrophobic coating capable of resisting icing for a long time, which specifically comprises the following steps: step 1, cleaning and sandblasting coarsening treatment is carried out on the surface of a base material; step 2, blending the epoxy resin, the curing agent and the first solvent to obtain an epoxy resin solution; step 3, dispersing the submicron particles and the nanoparticles in a second solvent, and adding a silane coupling agent to obtain a particle composite suspension; step 4, spraying the epoxy resin solution obtained in the step 2 on the surface of the substrate treated in the step 1, and semi-curing the epoxy resin adhesive; step 5, spraying the particle composite suspension obtained in the step 3 on the surface of the base material obtained in the step 4, and completely curing; and 6, obtaining the durable anti-icing super-hydrophobic coating. The invention has the beneficial effects that: the super-hydrophobic coating prepared on the surface of each substrate has good durability and firmness, and has durable anti-icing performance. |
