Preparation method for flake nickel powder in alkaline media

The invention provides a preparation method for flake nickel powder in alkaline media. According to the method, water, nickel salt, complexing agents, nickel plating brighteners, dispersing agents, antioxidants, alkalis, a flake alkali compound crystallization template and reducing agents are used as raw materials, a chemical plating method is adopted, the surface of the flake alkali compound crystallization template is nickelplated until a nickel ion reaction is complete, and after the reaction is over, the flake nickel powder is directly obtained through separation, purification and processing treatment technological processes without ball milling. The technical scheme has a series of beneficial effects that energy consumption is low, environmental pollution is low, the production process is simple, the process route is short, large-scale production equipment investment is low, the production efficiency is high, the production cost is low, the dispersing performance and conductivityof a product are good, an
