Abstract

The invention discloses a preparation method of a cable sheath material of a mine cable. The method comprises the following steps: carrying out primary mixing on chloroprene rubber, chlorinated polyethylene and styrene butadiene rubber; adding polyurethane, stearinic acid, magnesium oxide, aluminum hydroxide, zinc oxide and organic montmorillonite into a primary mixed compound for secondary mixing; adding a vulcanizing agent, an antioxidant, N,N'-bis(furfurylidene)acetone, magnesium hydroxide and a promoter into secondary mixed compound for tertiary mixing; and carrying out sulfuration on a tertiary mixed compound to obtain the cable sheath material of the mine cable. The invention also brings forward a mine cable. The mine cable comprises a cable core, an insulation layer, a buffer layer and a sheath layer. The periphery of the cable core is wrapped by the insulation layer, the periphery of the insulation layer is wrapped by the buffer layer, and the periphery of the buffer layer is wrapped by the sheath layer. The obtained cable has the advantages of high strength and high toughness.

Description

technical field [0001] The invention relates to the field of cables, in particular to a mine cable and a method for preparing the cable sheathing material thereof. Background technique [0002] At present, the cables used in mines are used in harsh environments, so the cables used in mines are required to have the characteristics of high strength and good toughness, and the strength and flexibility of the cables mainly depend on the performance of the outer sheath layer of the cables.
