Abstract

The invention discloses a manufacturing method of graphene composite aluminum wire-shaped materials. The manufacturing method comprises the steps that nano-powder graphene is prepared; graphene nano powder bodies are mixed with aluminum powders, grinding and pressing into alloy ingots are carried out in an oxygen-free environment; firing and dehydrating of the alloy ingots are carried out; moltenpure aluminum is introduced into the alloy ingots, and graphene composite aluminum rods are obtained by continuous casting and rolling; and the graphene composite aluminum wire-shaped materials with different wire diameters are obtained by drawing the graphene composite aluminum rods. According to the manufacturing method of the graphene composite aluminum wire-shaped materials, the problem that graphene and aluminum are not mutually soluble is solved, the strength of a single wire is improved greatly, the repetition and magnify are easy and pollution-free.

Description

technical field [0001] The invention relates to a method for manufacturing a linear material, in particular to a method for manufacturing a graphene-composite aluminum linear material. Background technique [0002] With the continuous development of graphene preparation technology, the pilot test and mass production routes of graphene are becoming more and more mature, and a large number of graphene preparation manufacturers and application products have emerged on the market. Graphene's excellent two-dimensional planar sheet structure and conductive properties shine in some fields, such as energy storage materials, lithium-ion batteries, semiconductor materials, conductive inks, etc. [0003] Aluminum stranded wire is a bare wire. At present, aluminum-clad steel strand (LGJ) is generally used as the wire in China; the steel core mainly plays the role of increasing strength, and the aluminum strand mainly plays the role of transmitting electric energy. Depending on the vol...
