Novel environmental-protection cable material for high power and preparation method thereof

Abstract

The invention discloses a novel environmental-protection cable material for high power; the cable material is prepared from the following raw materials in parts by weight: 45-65 parts of PVC resin, 8-10 parts of pottery clay, 3-4 parts of ammonium polyphosphate, 2-4 parts of diatomite, 3-5 parts of polyethylene wax, 15-25 parts of carbon black N550, 3-4 parts of an anti-aging agent MB, 2-3 parts of polypropylene, 5-6 parts of amine polyphosphate, 2-4 parts of calcium stearate, 2-3 parts of tert-butyl peroxyacetate, 4-5 parts of thermoplastic polyurethane, 2-4 parts of calcium ferrite, 1-2 parts of 1,4-bis(tert-butyldioxyisopropyl)benzene, and 8-12 parts of a filling agent. The cable material is simple in preparation method, has excellent tension and tensile force, and has relatively strong toughness and aging resistance properties; and the selected raw materials are all the environmental protection materials, so that the cable material has no pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power environment-friendly new cable material and a preparation method thereof. Background technique [0002] With the development of my country's economy and the rapid development of the communication industry, more and more high-power equipment is used, which puts forward higher requirements for the performance of cables. The withstand power of the cable is linearly related to the difference between the maximum temperature of the inner conductor and the ambient temperature, and the maximum working temperature of the inner conductor is limited by the cable insulation material. The long-term working temperature of the cable insulation material is the maximum allowable working temperature of the inner conductor, but at present Most of the cable materials on the market do not have excellent high temperature resistance and cannot meet the needs of current high-power ...
