The invention provides a super-hydrophobic anti-icing corrosion-resistant surface of a steel plate and a preparation method of the super-hydrophobic anti-icing corrosion-resistant surface. The super-hydrophobic anti-icing corrosion-resistant surface of the steel plate is provided with a micro-nano-scale double coarse structure and a low-surface-energy substance monomolecular layer modified on the surface of the micro-nano-scale double coarse structure; the micro-nano-scale double coarse structures comprise large convex structures located on the lower layer and small convex structures located on the upper layer, each large convex structure is provided with a plurality of small convex structures, the size of each large convex structure is 1-100 microns, and the size of each small convex structure is 50-500 nm; the static contact angle between the super-hydrophobic anti-icing corrosion-resistant surface of the steel plate and water is larger than 150 degrees. The preparation method specifically comprises the four steps of surface pretreatment, chemical etching, low surface energy modification and cleaning and drying. According to the technical scheme, the problem that the surface of a common steel plate is prone to being covered with water, iced and rusted is solved.
