The invention discloses a manufacturing method of atomized silver and zinc oxide electrical contact materials containing additives. The method comprises the following steps that (1), according to the material ratio of silver and zinc oxide electrical contacts needing preparing, the dosages of needed pure silver blocks, needed pure zinc blocks and needed salt-class compounds containing the additives are calculated, and the needed pure silver blocks, and the needed pure zinc blocks and the needed salt-class compounds containing the additives are weighed for the standby; (2), the pure silver blocks and the pure zinc blocks are atomized to be silver and zinc alloy powder; (3), the salt-class compounds containing the additives are prepared to form a water solution or an ethyl alcohol solution, the silver and zinc alloy power is added into the solution to be mixed, and silver and zinc alloy powder slurry with the salt-class compounds containing the additives evenly distributed is obtained; (4), the slurry is dried and smashed, and silver and zinc alloy powder with the salt-class compounds containing the additives evenly distributed is obtained; (5), pre-oxidation processing, isostatic pressing formation, sintering and extrusion are carried out on the alloy powder so as to obtain the atomized silver and zinc oxide electrical contact materials containing the additives. The method well solves the problem of segregation of the additives caused by a traditional atomization and power mixing process, and improves the degree of densification, the processing performance, the material yield and the electrical property of the materials.
