The invention relates to a preparation method of a 3 mm Zn-Cu-Ti alloy wire for spraying. The method comprises the following steps that 1. pure copper blocks and titanium sponge are weighed in proportion, and are smelted into a Cu-Ti intermediate alloy by adopting a non-consumable vacuum arc furnace, and after cooled, and the alloy is broken into small blocks; 2, a resistance furnace is adopted for smelting a Zn-Cu-Ti alloy, then Cu-Ti intermediate alloy is put into zinc melt, heat preservation is conducted till the Cu-Ti intermediate alloy is completely dissolved into the zinc melt, and thenthe Zn-Cu-Ti alloy melt is poured into a graphite mold; 3, a cylindrical cast ingot is put into the resistance furnace, is heated to 150 DEG C-180 DEG C, and taken out, and a layer of graphite emulsion lubricant is brushed over the cast ingot; and 4, the Zn-Cu-Ti cast ingot is put into an extrusion mold, the cast ingot and the extrusion mold are heated together, then isothermal extrusion is conducted, and one-step deformation is conducted to obtain the alloy wire. According to the preparation method, on one hand, the problem that a large amount of zinc volatilizes in a smelting process is solved, the zinc-copper-titanium alloy wire is prepared in one step, preparation procedures are reduced, the production cost is greatly reduced, and the productivity is improved.
