Low energy consumption cable material for large power and preparation method thereof

Abstract

The invention discloses a low energy consumption cable material for large power and a preparation method thereof. The low energy consumption cable material is prepared from 4-6 parts by weight of linear low density polyethylene, 20-30 parts by weight of polyvinyl chloride resin, 4-7 parts by weight of molybdenum disulfide, 3-5 parts by weight of boehmite, 10-15 parts by weight of methyl vinyl silicone rubber, 3-5 parts by weight of dioctyl terephthalate, 2-3 parts by weight of oxalyl dihydrazide, 2-4 parts by weight of nanometer magnesium-lanthanum alloy powder, 25-35 parts by weight of silicone rubber, 3-5 parts by weight of ethyoxy lauramide, 2-4 parts by weight of oil DOP, 4-5 parts by weight of purified dioctyl terephthalate, 3-6 parts by weight of an ethylene-vinyl acetate copolymer, 1-2 parts by weight of an antiager OD and 8-12 parts by weight of a filler. Through a reasonable formula and improved processes, the preparation method reduces production energy consumption. The low energy consumption cable material has a high plastification degree and excellent processing properties and is suitable for popularization application.

Description

technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power low-energy 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 equipment.
