Abstract

The invention discloses a flame-retardant and high-temperature-resistant cable and a preparation method thereof. The cable is prepared from, by weight, 40 to 50 parts of ethylene-vinyl acetate copolymer, 10 to 20 parts of high-density polyethylene, 8 to 12 parts of liquid polyisobutene, 4 to 10 parts of microcrystalline wax, 3 to 9 parts of high-aluminum fiber, 2 to 6 parts of antioxidant, 6 to 10 parts of silicon carbide powder, 7 to 14 parts of calcium carbonate powder, 8 to 18 parts of carbon nanotube, 3 to 9 parts of molybdenum trioxide and 2 to 6 parts of aluminum hydroxide. The preparation method is simple. The prepared cable is good in flame retardance and high temperature resistance and has good mechanical strength, wear resistance and traction resistance, and the service life of the cable in a severe environment is prolonged.

Description

technical field [0001] The invention relates to the technical field of cable preparation, in particular to a flame-retardant, high-temperature-resistant cable and a preparation method thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. The cable has the characteristics of internal electrification and external insulation. Cables 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. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] The existing cables have poor comprehensive mechanical properties, p...
