NOVELTY - Preparing graphene aluminum base composite material involves preparing graphene, aluminum powder and aluminum alloy sheet, where graphene and aluminum powder are prepared in ball mill under liquid nitrogen environment, graphene are adhered to surface of aluminum powder to formed powder mixture is placed into vacuum drying box to dried, then dried powder mixture is dispersed on surface of aluminum alloy board, where mass ratio of powder mixture and aluminum alloy plate is 1:3-5, where aluminum alloy plate is folded, rolled and compounded as nip point folded position. USE - Method for preparing graphene aluminum base composite material (claimed). ADVANTAGE - The method enables to prepare graphene aluminum base composite material is easy to prepare, easy for industrial popularization and cost-effective, and has relatively uniform and good combination of graphene with aluminum substrate. DETAILED DESCRIPTION - Preparing graphene aluminum base composite material involves preparing graphene, aluminum powder and aluminum alloy sheet, where graphene and aluminum powder are prepared in ball mill under liquid nitrogen environment, graphene are adhered to surface of aluminum powder to formed powder mixture is placed into vacuum drying box to dried, then dried powder mixture is dispersed on surface of aluminum alloy board, where mass ratio of powder mixture and aluminum alloy plate is 1:3-5, where aluminum alloy plate is folded, rolled and compounded as nip point folded position, then controlled rolling speed so that two layers of aluminum alloy air along with rolling to discharged and repeated for 5-10 times folded and rolled composite aluminum base composite material, where prepared graphene composite rolling pass deformation is not less than 50%, then heated graphene aluminum base composite material for 5-8 hours at 620-640 degrees C to obtained finished product.
