Abstract

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 products are good; and the method is suitable for large-scale production and capable of solving the problems exist in the ball milling process when the ball milling process is used for preparing the flaky nickel powder, and has good industrialization prospect.

Description

technical field [0001] The invention relates to a preparation method of flaky nickel powder in an acidic medium, and belongs to the technical field of preparation of metal powder materials. Background technique [0002] Metal powders are divided into four types according to particle shape: spherical, random particle, flake and wire. Different from spherical metal powder and granular metal powder, flake metal powder has excellent catalytic performance, excellent sintering performance, excellent thixotropic performance, excellent adhesion, good shielding effect, excellent electromagnetic wave reflection ability and excellent Excellent electrical conductivity makes it widely used in chemical catalysis, powder metallurgy, conductive coatings, conductive adhesives, conductive inks and conductive pastes. [0003] At present, spherical metal powders or granular metal powders are mostly used in the fields of chemical catalysis, electromagnetic shielding coatings, radar wave reflect...
