Problems solved by technology

[0005] With the development of my country's modern industry, cables are used in all aspects of the national economy and people's lives. People put forward higher requirements for the performance of high-temperature cables and high-temperature-resistant cable materials. Cables and cable materials with a single high-temperature resistance performance can no longer be used. To meet people's needs for cables, cables and cable materials must develop in the direction of functionalization and diversification

Abstract

The invention discloses a high-temperature-resistant, heat-conducting, tear-proof cable, which comprises a conductive cable core, an inner protective sheath and an outer protective sheath, the inner protective sheath covers the conductive cable core, the outer protective sheath covers the inner protective sheath, and the outer protective sheath The periphery is provided with corrugated textures that are spirally wound around the periphery of the outer protective sheath to facilitate high-temperature heat dissipation. The invention has good impact resistance, high toughness, strong tear resistance, good flame retardancy, and strong high temperature resistance. The outer protective cover is provided with a wrinkled texture that is spirally wound around the outer protective cover for high temperature heat dissipation. It is used to increase the surface area of ​​the outer protective sheath, which is beneficial to the high temperature heat dissipation of the cable and has good thermal conductivity.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-temperature-resistant, heat-conducting, tear-resistant cable. Background technique [0002] Phenolic resin is a widely used thermosetting resin, which has many good properties, such as strong mechanical strength, stable size, good high temperature resistance, excellent electrical insulation, and the inherent flame retardancy of the resin itself, smoke Low rate and ablation resistance, etc. [0003] Graphene is composed of closely arranged single-layer sheets of carbon atoms, and the lattice structure is similar to a single-layer two-dimensional honeycomb. At present, graphene material is recognized as the lightest and thinnest two-dimensional material in the world, with excellent properties, such as: large specific surface area, excellent mechanical properties, low friction coefficient and high thermal conductivity. In the process of synthesizing graphene, an important gr...
