Low-smoke zero-halogen cable material for high power and preparation method thereof

Abstract

The invention discloses a low-smoke zero-halogen cable material for high power. The low-smoke zero-halogen cable material comprises, by weight, 2-4 parts of chlorcosane, 6-8 parts of calcium carbonate, 3-4 parts of linear low-density polyethylene, 2-4 parts of melamine cyanurate, 2-3 parts of sulphur, 1-2 parts of accelerant, 3-5 parts of dioctadecyl 3,3'-thiodipropionate, 2-3 parts of boric acid, 2-4 parts of diisooctyl sebacate, 1-3 parts of dimethyltin bis(isooctylmercaptoacetate), 2-4 parts of triallyl isocyanurate, 4-5 parts of low-molecular PE wax, 40-60 parts of ethylene propylene diene monomer, 2-5 parts of trimellitate and 8-12 parts of filling agent. The low-smoke zero-halogen cable material has the excellent mechanical performance, heat resistance and weather resistance, the added triallyl isocyanurate can remarkably shorten the vulcanizing time, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power low-smoke halogen-free 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-powe...
