| titleOfInvention | Preparation method of flaky silver powder |
| abstract | The invention discloses a preparation method of flake silver powder, which takes water, silver salt, complexing agent, silver plating brightener, dispersant, alkali or acid, flake alkaline compound crystallization template or flake acidic compound crystallization template or sublimable flake compound crystallization template and reducing agent as raw materials, adopts a chemical plating method to plate silver on the surface of the flake compound crystallization template until silver ions completely react, and directly obtains the flake silver powder without ball milling through separation purification and processing process after the reaction is finished. The technical scheme of the invention has the advantages of low energy consumption, small environmental pollution, simple production process, short process route, small investment on large-scale production equipment, high production efficiency, low production cost and good dispersion performance and conductivity of products, is suitable for large-scale production, solves the problems in the conventional processes for preparing the flake silver powder by using a ball milling method and a template method, and has good industrial prospect. |
