The invention discloses a preparation method of a silver tin oxide target material for a contact material. The preparation method comprises the following steps: S1, powder spraying: preparing silver tin oxide powder with the purity being greater than or equal to 99.95% and the particle size being 10-40nm; s2, a base tube is prepared, specifically, a stainless steel tube serves as a target material base tube, sand blasting treatment and bottoming treatment are sequentially conducted on the target material base tube, so that dirt on the surface of the base tube is removed, and an active surface is obtained; according to the silver tin oxide target material, the target material prepared through the processes of powder spraying, base tube preparation, cold spraying and the like has the excellent density performance, meanwhile, the wear resistance and the conductivity can be harmoniously improved, tin oxide can be jointly matched with tin oxide and silver through ball milling treatment through modification treatme
