摘要
The present invention relates to a new method for preparing a silver-based electrical contact material, comprising following steps of: (a) providing a carbonaceous mesophase solution; (b) adding a silver source into the carbonaceous mesophase solution and stirring to obtain a compound; (c) removing a solvent from the compound to obtain a solid; (d) performing a heat treatment on the solid, and obtaining a silver-based electrical contact material. The silver source is silver powder prepared by means of a chemical method. By means of the method, a uniform carbonaceous coating on silver is implemented, the silver is uniformly distributed in a nanometer scale, and a diamond is generated in situ of a material after being sintered. The silver-based electrical contact material processed by means of this method shows an excellent mechanical wear resistance and electrical property.
