Preparation method for flaky nickel powder

The invention provides a preparation method for flaky nickel powder. According to the method, water, nickel salt, a complexing agent, a nickel plating brightening agent, a dispersing agent, an antioxidant, a sublimable flaky compound crystal template and a reducing agent serve as raw materials, a chemical plating method is adopted, the surface of the flaky compound crystal template is plated withnickel until nickel ions are reacted completely, and after a reaction is completed, by means of the technological processes of separation and purification and processing treatment, the flaky nickel powder is directly obtained without ball milling. By means of the technical scheme, the preparation method has a series of beneficial effects that the energy consumption is low, the environmental pollution is small, the production process is simple, the process route is short, the investment of large-scale production equipment is small, the production efficiency is high, the production cost is low,and the dispersing perform
