The invention relates to the technical field of evaporation material production, and discloses a preparation method of an aluminum evaporation material, which comprises the following steps: continuously casting an aluminum ingot into an aluminum bar with the diameter of 8mm; the aluminum bar is subjected to annealing treatment; one end of the aluminum bar subjected to annealing treatment is pointed; the pointed aluminum bar is drawn on a wire drawing machine, the single-pass variable of drawing is 20-30%, drawing is repeated for 2-10 times, the total variable of drawing is lower than 98%, and an aluminum wire is obtained; the aluminum wires are cut off, and aluminum particles are obtained; cleaning and drying the aluminum particles to obtain an aluminum evaporation material; through the method, the aluminum evaporation material with good surface quality is prepared, and meanwhile, we surprisingly discover that the smaller the single-pass deformation is, the more the drawing passes are, and the better the surf
