Abstract

The invention relates to an ethylene-propylene-diene monomer material used for an electric wire and a preparation method of the ethylene-propylene-diene monomer material. The ethylene-propylene-diene monomer material comprises the following components in parts by weight: 85-115 parts of an ethylene-propylene-diene monomer, 2.5-10 parts of acrylic acid, 1.5-7 parts of sodium stearate, 1.5-6 parts of an initiator, 2.5-8 parts of an antiager, 0.5-1.5 parts of an inorganic filler and 1-2 parts of a fire retardant. According to the preparation method, a mixture is added to a double-screw extruder to carry out extrusion pelleting. The ethylene-propylene-diene monomer material used for the electric wire is high in strength, good in anti-aging, good in flame retardant property, stable in power supply property and convenient to process.

Description

technical field [0001] The invention relates to a material for cable manufacturing and a preparation method thereof, in particular to a rubber material for electric wires and cables and a preparation method thereof. Background technique [0002] EPDM rubber has excellent electrical properties, excellent heat resistance, good low temperature flexibility, etc., so it is widely used in cables, especially mine cables and marine cables. However, the traditional EPDM rubber cannot meet the requirements for high cable strength, and its processing performance is poor, and its anti-aging and flame-retardant properties cannot meet the actual use requirements. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to overcome the deficiencies in the prior art, to provide a rubber material for wire and cable with high strength, good aging resistance, good flame retardancy and stable power supply performance, and to provide a rubber material capabl...
