Abstract

The invention provides a high-wear-resistance nitrile rubber composite cable material. The high-wear-resistance nitrile rubber composite cable material is prepared from components in parts by weight as follows: 100 parts of nitrile rubber, 4-5 parts of an accelerant, 2-2.5 parts of an antioxidant, 8-13 parts of a fire retardant, 10-15 parts of filler, 1.5-2 parts of a coupling agent, 5-10 parts of a plasticizer, 1-1.5 parts of a vulcanizing agent, 2.5-3 parts of an anti-aging agent, 6-8 parts of modified compound zirconia, 4 parts of zinc oxide and 2 parts of stearic acid. The invention further provides a preparation method of the nitrile rubber composite cable material. The wear resistance of the nitrile rubber composite cable material is very high.

Description

technical field [0001] The invention relates to a cable material, in particular to a highly wear-resistant nitrile rubber composite cable material and a preparation method thereof. Background technique [0002] Nitrile rubber is polymerized from butadiene and acrylonitrile, and can be divided into general-purpose nitrile rubber and special nitrile rubber according to uses. Nitrile rubber has the following properties: [0003] 1. Excellent oil resistance and solvent resistance, the higher the acrylonitrile content, the better the oil resistance [0004] 2. General physical and mechanical properties [0005] 3. Good heat resistance [0006] 4. Good water resistance and low air permeability [0007] 5. It can be mixed with other rubber or plastic to improve the performance of the rubber. [0008] Nitrile rubber can be used alone or mixed with polyvinyl chloride plastic to make oil-resistant electrical insulation sheaths, such as motor lead wires, oil and mine cables, and m...
