Abstract

The invention relates to the technical field of conductive materials and preparation methods thereof, in particular to conductive grease and a preparation method thereof. The conductive grease comprises the following components in part by weight: 5 to 15 percent of lithium soap, 60 to 70 percent of synthetic basic oil, 23 to 33 percent of pure copper powder, 1 to 2 percent of tin powder and 1 to 2 percent of silver powder. The preparation method comprises the following steps of: weighing the synthetic basic oil, the pure copper powder, the tin powder and the silver powder, adding the synthetic basic oil, the pure copper powder, the tin powder and the silver powder into a reactor, and uniformly mixing to obtain a pasty mixture for backup use; weighing the lithium soap, and smashing the lithium soap into powder; adding the lithium soap powder into the pasty mixture, uniformly mixing, and stirring and grinding to obtain the conductive grease; and putting the conductive grease into a package bottle to obtain a finished product. The conductive grease is relatively high in electrical conductivity, high in electrochemical corrosion resistance and heat resistance and high in conductive connection reliability; the preparation method for the conductive grease is scientific and rational; and the process is simple and convenient.

Description

[technical field] [0001] The invention relates to the technical field of conductive materials and preparation methods thereof, in particular to a conductive grease and a preparation method thereof.
