The invention discloses a zinc electrode for an alkaline secondary battery and a preparation method of the zinc electrode, the zinc electrode comprises an electrode material and a current collector material, the electrode material basically comprises zinc oxide, graphite, polytetrafluoroethylene (PTFE) and an additive, and the current collector material is tinplate; the method comprises the following steps: firstly, manufacturing an electrode without a current collector material, and then compounding the electrode without the current collector material with the current collector material. Themethod is low in manufacturing cost, a solvent-free mixing process is adopted, the preparation method is simple, the preparation time is short, the mixing process can be completed within only 0.1-1 h,the energy consumption in the process is very low, and the prepared zinc electrode is high in precision. 本发明公开了一种碱性二次电池用锌电极及其制备方法，所述锌电极包括电极材料和集流体材料，电极材料的基本组成为：氧化锌、石墨、聚四氟乙烯(PTFE)及添加剂，集流体材料为马口铁；首先制作不含集流体材料的电极，然后将不含集流体材料的电极和集流体材
