NOVELTY - A lead-graphene composite material preparing method involves dispersing graphene nanometer sheets into anhydrous alcohol at ratio of 1: 500-1500 to obtain a black graphene solution. Lead powder is added into the graphene solution, anhydrous alcohol and a lead-based composite material containing the graphene nanometer sheets are packed into a ball milling tank for ball milling and mixing for 20-28 hours, followed by drying ball milled slurry, and compacting the dried powder and sintering to obtain product. USE - Method for preparing lead-graphene composite material. ADVANTAGE - The material has good bonding of lead particles and graphene, and increased the contact interface of lead and graphene to make dilution and remelting of the lead-based graphene composite material.
