The invention discloses a fused zinc aluminum corrosion resistant coating material and a preparation method of the fused zinc aluminum corrosion resistant coating material. According to the fused zincaluminum corrosion resistant coating material, rare earth oxide powder with the nanometer particle size or sub-micron particle size is added to the surface of metal ceramic spray powder, so that thefused zinc aluminum corrosion resistant coating material is obtained. By means of the dispersion strengthening effect of particles among slice layers, the strength of the integral material is improved, the crack extension path is lengthened, and therefore the penetration process of corrosive liquid along cracks is prolonged, and the corrosion resistance of a coating is improved.
