The elastic material comprises a flame-retardant component A and a catalysis component B with the weight proportion of 100:(4-6), wherein the flame-retardant component A comprises 30-70 parts of ethylene propylene diene monomer, 30-70 parts of ethylene-octylene copolymer, 15-25 parts of nitrile rubber, 1-6 parts of silane crosslinking agent, 0.3-1.5 parts of graft initiator, 0.1-5 parts of antioxygen, 0.2-2 parts of lubricant, 0.1-4 parts of 3-aminopropyl trimethoxy silane and 50-150 parts of modified flame retardant; and the catalysis component B comprises 100 parts of ethylene-vinyl acetate and/or ethylene-octylene copolymer, 3-50 parts of organosilicone flame retardant, 1-5 parts of first antioxygen, 1-10 parts of second antioxygen and 1-8 parts of crosslinking catalyst. The elastic material is a novel halogen-free low-smoke flame-retardant cable material, and has the advantages of excellent flame resistance and elasticity, low smoke, low toxicity, excellent processing performance and low cost.

Description

technical field [0001] The invention relates to a halogen-free low-smoke flame-retardant cable material and a preparation method thereof, in particular to a silane self-crosslinking halogen-free low-smoke flame-retardant elastic material and a preparation method thereof. Background technique [0002] Halogen-free low-smoke flame-retardant cable materials are more and more popular in the wire and cable industry because of their superior performance such as environmental protection, low smoke, and flame retardancy. Many manufacturers regard it as a potential replacement for PVC materials. Low-smoke flame-retardant cable materials are mainly divided into two types: cross-linked type and thermoplastic type. Thermoplastic materials have the advantage of being recyclable, and are mainly used in power cables, control cables, and communication cables as insulation and sheath layers for such cables. Cross-linked materials are mainly electron beam irradiation cross-linked materials, ...
