Abstract

The invention discloses a modified terpolymer EP rubber containing cable sheath material and preparation method thereof, and the product comprises the following raw materials: modified terpolymer EP rubber, hydrogenated butadiene-acrylonitrile rubber, blast furnace slag, zeolite molecular sieve, aluminium carbide, promoter 808, promoter CZ, N-(beta-aminoethyl)-gamma-aminopropyl trimethoxysilane (triethoxysilane), barium ricinoleic acid, anti-oxidant 1010, diisobutyl phthalate and phosphate ester; the invention employs modified terpolymer EP rubber as main material, and the terpolymer EP rubber is modified, thereby the product has the characteristics of low-smoke, halogen free, flame retardation, high mechanical strength and high insulation resistor, moreover, the product has good elasticity and flexibility, simultaneously the nanometer attapulgite in the raw material is used as strengthening agent, and nanometer level titanium dioxide and aluminium carbide are used as filling materials.

Description

technical field [0001] The invention relates to a cable sheath material, in particular to a cable sheath material containing modified EPDM rubber and a preparation method thereof. Background technique [0002] With the rapid development of the economy, wires and cables are widely used in various industries and fields, and electrical fire accidents occur frequently, and the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. Excessive and corrosive gases are dangerous factors in fires, which hinder people's safe evacuation and fire fighting work, causing serious losses of life and property. The quality requirements of sheathing materials are increasing day by day. The invention provides a cable sheathing material containing modified EPDM rubber and a preparation method thereof. Contents of the invention [0003] The object of the present invention is to provide a kind of cable sheath material containing modifie...
