Abstract

The invention discloses a new copper and copper alloy coated graphite powder and graphene material, which is composed of the following raw materials in parts by weight: copper sulfate 20-50, stannous sulfate 3-5, zinc sulfate 2-5 , graphite powder 20-50, graphene 20-25, reduction aid 0.8-1, aluminum dihydrogen phosphate 1-2, composite aid 0.1-0.2, the invention enables metal materials to be completely coated on graphite and graphene particles The surface gradually forms a cladding layer and becomes a whole, which solves defects such as uneven mixing; a metal layer is added to the surface of graphite and graphene, which effectively improves the difficulty of direct compression molding of graphite materials, which is difficult to Issues such as powder metallurgy have greatly improved production efficiency and improved molding conditions; a layer of metal is completely coated on the surface of graphite materials, which not only improves and improves the uniformity of graphite and metal, but also improves electrical and thermal conductivity.

Description

technical field [0001] The invention mainly relates to the field of new materials, in particular to a copper and copper alloy-coated graphite powder and graphene new material and a preparation method thereof. Background technique [0002] Most of the existing mixed materials of copper and graphite use a single copper powder and copper alloy powder, and add graphite powder according to a certain ratio, then put it into a mixer, and mix it for a certain period of time to form a mixed powder. Or graphite powder is pressed into shape by adding pitch, and then the pitch is decomposed by high-temperature graphitization to form graphite products. The composite materials obtained by these traditional methods have certain defects. First, the density and quality of metal are different from those of graphite and graphene. The difference is very huge. The effect of uniform distribution of multiple materials cannot be achieved through long-term mixing of mixing equipment. At the same tim...
