Graphene composite material cable and production method thereof

Abstract

The invention provides a graphene composite material cable which comprises a conductor layer, an insulating layer, an outer covering layer and a protective layer which are arranged from inside to outside in turn. The protective layer material is the graphene composite material. The raw material of the graphene composite material comprises the following components according to the weight percentage: 4%-6% of graphite, 2%-3% of sodium nitrate, 12%-18% of potassium permanganate, 12%-13% of concentrated sulfuric acid, 34%-38% of deionized water, 10%-11% of hydrogen peroxide, 6%-7% of hydrazine hydrate, 5%-6% of copper sulfate, 5%-6% of aluminum block and 2%-4% of fireproof material. The graphene composite material is utilized to replace the metal braided shielding material and the aluminum foil material, the process is simple and the production cost is reduced, and the cable has remarkable economic benefits.

Description

technical field

[0001] The technical invention relates to the field of cables, in particular to a graphene composite cable and a production method. Background technique

[0002] With the gradual acceleration of the urbanization process, urban planning is becoming more and more modern. In the process of urban construction, cable entry into the ground has become the minimum construction requirement. At the same time, in the process of urban transformation, it is also necessary to put various cables erected in the air into the ground. The requirements for the cable are: the cable needs to have the characteristics of high strength, good rigidity and toughness. In addition, due to the characteristics of the cable itself, it also needs to have the characteristics of shielding to achieve the purpose of shielding electromagnetic interference.

[0003] At present, it is common to add a metal braid formed by aluminum foil and copper wire braid between the insulation and the outer la...
