Abstract

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, and the like, the method is suitable for large-scale production, the problems existing in the process of preparing the flake nickel powder by ball milling are solved, and the industrialization prospects are good.

Description

technical field [0001] The invention relates to a preparation method of flaky nickel powder in an alkaline medium, belonging 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...
