Special environment-friendly high-corrosion-resistance zinc-aluminum coating for metal components and preparation method thereof

The invention relates to the field of zinc-aluminum coatings, in particular to a special environment-friendly high-corrosion-resistance zinc-aluminum coating for metal components and a preparation method thereof. A special environment-friendly high-corrosion-resistance zinc-aluminum coating for metal components comprises the following raw materials in parts by mass: 20-40 parts of zinc powder, 10-25 parts of aluminum powder, 5-15 parts of a wetting agent, 1-3 parts of a dispersing agent, 10-20 parts of a resin material, 0.5-1 part of a defoaming agent, 10-15 parts of a modified filler and 40-55 parts of a solvent. The prepared environment-friendly high-corrosion-resistance zinc-aluminum coating special for the metal component has good corrosion resistance and environmental protection performance, meanwhile, excellent coating water resistance, high-temperature/chemical stability, aging resistance, wear resistance and other performance are reserved, and good comprehensive performance is obtained; the zinc-alumi
