Abstract

The invention discloses a super-soft, insulated and fireproof mineral cable containing graphene. The super-soft, insulated and fireproof mineral cable containing graphene takes graphene as a conductor, and the graphene conductor is placed in a ceramic polyolefin insulation layer, can improve the signal transmission of the cable on one hand and has a good conduction effect on the other hand. The graphene conductor at least comprises two materials, namely, graphene and a conductive adhesive, the conductive adhesive is used for bonding graphene powder, the conductive adhesive with higher viscosity is used, and a conductive wire with super-soft performance is prepared from the graphene conductor. The cable has higher signal transmission and conduction capability than a conventional cable. The cable not only has the high signal transmission and conduction capability, but also has high fireproof capability.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a graphene super-flexible mineral insulated fireproof cable. Background technique [0002] The structure of traditional insulated cables is generally two layers, the inner layer is a metal conductive layer, and the outer layer is a non-metallic insulating layer. Such cables can only be used in ordinary places, and have the disadvantages of flammable insulation, easy aging, difficulty in high temperature resistance, and short service life. [0003] Copper is usually used as the conductive layer in cables, but copper itself is easily oxidized and corroded, and the texture of copper is soft and has poor ductility. In the prior art, in order to solve the problem of copper being oxidized and corroded, electroplating is usually performed on the surface of conductor copper, and a layer of anti-oxidation material is plated. However, this electroplating technique increases the production...
