Abstract

The invention provides an irradiation-resistant halogen-free flame-retardant ethylene-propylene cable material, relating to the technical field of cables. The irradiation-resistant halogen-free flame-retardant ethylene-propylene cable material is prepared from 100 parts of ethylene-propylene rubber, 60-80 parts of aluminum oxide, 1-3 parts of gamma-ray absorbent and 10 parts of zinc oxide by a double screw extruder. The cable material is incombustible, and can prevent combustion. The flame retardancy grade can reach Grade V-0. The cable material can not easily generate halogen-containing toxic substances or smoke dust during combustion. The gamma-ray irradiation resistance accumulated dose is up to 288 Mrad.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a radiation-resistant halogen-free flame-retardant ethylene-propylene cable material. Background technique [0002] Power cables have important applications in many fields, and cables in some special fields may need to withstand a large amount of radiation exposure, while general cable materials will accelerate aging and denaturation after long-term or large-dose radiation exposure, thus This will shorten the service life and affect the safety of electric equipment. Contents of the invention [0003] The object of the invention is to provide a halogen-free flame-retardant cable material with good radiation resistance. [0004] In order to solve the existing problems in the background technology, the technical scheme adopted by the present invention is as follows: it is made of raw materials of 100 parts of ethylene-propylene rubber, 60-80 parts of aluminum oxide, 1-...
