Method for preparing flaky nickel powder through acid medium

The invention provides a method for preparing flaky nickel powder. The method is characterized in that water, nickel salt, a complexing agent, a nickel plating brightening agent, a dispersing agent, an antioxidant, acid, a flaky acidic compound crystal template and a reducing agent are taken as raw materials, nickel plating is carried out on the surface of the flaky acidic compound crystal template by adopting a chemical plating method until nickel ions react completely, and after the reaction is finished, the flaky nickel powder is directly obtained through a separation and purification treatment and a processing treatment without ball milling. The technical scheme of the method has the advantages that the energy consumption is low, environmental pollution is low, the production process is simple, the process route is short, the investment to the large-scale production equipment is low, the production efficiency is high, the production cost is low, and the dispersion performance and the conductivity of the p
