▎ 摘　　要

NOVELTY - Continuous preparation of graphene/copper composite lead comprises adding graphene powder and copper powder and mixing to obtain composite powder; subjecting composite powder to reduction treatment; adopting continuous extrusion to prepare graphene/copper composite wire billet; and carrying out multi-pass cold drawing. USE - The method is used for continuous preparation of graphene/copper composite lead. ADVANTAGE - The method realizes continuous production of line blank, uses multiple-pass drawing to realize further dispersion and orientation of graphene in copper matrix, and improves performance of composite conductor.
