The invention discloses a preparation method of high aluminum zinc-aluminum pseudo-alloy rod materials and wire materials. The preparation method comprises the following steps that a pure aluminum rod or an aluminum alloy rod and a pure zinc rod are put into a package of pure aluminum or aluminum alloy materials in a certain order, so that composite billet materials are formed; after heating the composite billet materials and extrusion dies of an extrusion machine, then the composite billet materials are put into the extrusion dies, the billet materials are extruded, and composite pseudo-alloy rod materials are prepared; and the obtained composite pseudo-alloy rod materials are drawn and diameter-reduced for multiple passes, and the wire materials are manufactured. According to the preparation method of high aluminum zinc-aluminum pseudo-alloy rod materials and wire materials, the aluminum rod and the zinc rod arranged in the package are extruded, so that the pseudo-alloy rod materials are formed by deformation and mixing, and then the rod materials are drawn and diameter-reduced to obtain the high aluminum zinc-aluminum pseudo-alloy wire materials. In the above process, the zinc and the aluminum are only deformed, the diameter is reduced, alloying does not happen between the zinc and the aluminum, the eutectic structure and the hard brittle phase are not produced, the deformation ability of the obtained rod materials is good, and a high aluminum zinc-aluminum coating layer is formed in heat spraying preparation of an anticorrosive coating after the pseudo-alloy wire materials are prepared by drawing and diameter reduction.
