A kind of oil-resistant cable material for railway locomotive vehicle cable and preparation method thereof

Abstract

The invention discloses an oil-resistant cable material used for railway locomotive vehicle cables, and a preparation method thereof. The oil-resistant cable material is prepared from the following raw materials by weight: 60-80 parts of high styrene rubber, 40-60 parts of butadiene-acrylonitrile rubber, 20-40 parts of chloroprene rubber, 15-20 parts of a bromomethyl-p-tert-octyl phenol formaldehyde resin, 10-15 parts of dibutyl maleate, 9-18 parts of polychlorinated biphenyls, 8-16 parts of tridichloropropyl phenyl silicate, 10-15 parts of nano barium titanate, 12-18 parts of heavy calcium carbonate powder, 5-10 parts of fly ash, 24-32 parts of fast extruding furnace carbon blanc N550, 2.5-4.5 parts of di-tert-butyl peroxide, 3-6 parts of dibenzoylquinone dioxime, 2-3 parts of isocyanatopropyl triethoxysilane, 3-5 parts of basic lead carbonate, 2-3 parts of calcium oxide, 6-12 parts of a transformer oil, 4-6 parts of liquid paraffin, 3-5 parts of glyceryl monopalmitate, 1-2 parts of tetraethylthiuram disufide, 2-3 parts of N-tert-butylbenzothiazole-2-sulphenamide, 1.5-2.5 parts of 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline and 10-15 parts of modified stone powder. The cable material provided by the invention has excellent oil resistance, solvent resistance and chemical corrosion resistance, and effectively prolongs the service life of the cable.

Description

technical field [0001] The invention relates to an oil-resistant cable material for railway locomotive and vehicle cables and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] In recent years, the national railway transportation has developed rapidly, the control of the railway system has become more and more complex, and there are more and more electrical control equipment, the demand for cables will inevitably increase accordingly, and the performance requirements for cable materials will also become more and more stringent. . Some places in railway locomotives have lubricating oil or fuel oil, so cables must have good oil resistance. However, the oil resistance of cable materials on the market can no longer meet the actual needs. Therefore, it is urgent to change the formula of traditional cable materials and develop a Oil-resistant cable compound to improve the safety performance of railway rolling stock cables. Con...
