Problems solved by technology

[0003] The current cable preparation method is not mature enough, which leads to high resistivity and insufficient conductivity of the cable. At the same time, after the cable is used for a long time and is damaged, the cable conductor is directly in contact with the air, which is easy to cause the cable to oxidize and rust, which seriously affects The effect of the use of the cable is that the service life is short, which brings a lot of trouble to the user

Abstract

The invention provides a strong-effect conductive oxidation-resistant cable and a preparation method thereof, which relate to the technical field of cable production. The cable is made of the following raw materials in parts by weight: copper 65-75 part, aluminum 15-25 part, graphene 14-16 part, carbon fiber 4-8 part, carbon black 2-4 part of zinc dialkyldithiophosphate, 25-35 part of tributyl phosphite, 8-12 part, styrene-diphenylamine 4-6 parts, O-Tert-alkyl benzotriazole 2-4 parts. The invention has the advantages of strong electric conductivity and oxidation resistance, adopts a pluralityof electric conductive fillers in the production process, so that the electric conductivity of the cable is better, the resistivity is small, and two kinds of anti-oxidation coating materials are prepared by adopting a plurality of antioxidants, so that the cable conductor is doubly protected, the cable and air contact are prevented from oxidizing and rusting, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to a powerful conductive and anti-oxidation cable and a preparation method thereof. Background technique [0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating layer that transmits power or information from one place to another. At present, the cables mainly include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. It is composed of strands or multi-strand wires and protective layers, and is used to connect circuits, electrical appliances, etc. [0003] The current cable preparation method is not mature enough, which leads to high resistivity and insufficient conductivity of the cable. At the same time, after the cable is used for a long time and is damaged, ...
