Abstract

The invention discloses a heatproof flame-retardant locomotive cable, which comprises a core and a sheath that wraps the core. The sheath comprises following components in parts by weight: 100 to 150parts of polyvinyl chloride, 30 to 60 parts of nitrile rubber, 5 to 25 parts of polyester type thermoplastic polyurethane elastomer, 3 to 15 parts of polyamide acid, 3 to 7 parts of zinc oxide, 0.3 to1.2 parts of stearic acid, 0.9 to 2 parts of sulfur, 6 to 15 parts of pentaerythritol, 5 to 15 parts of ammonium polyphosphate, 10 to 15 parts of melamine, 5 to 20 parts of titanium dioxide, 2 to 10parts of zinc hydroxyl stannate coated magnesium hydroxide, 3 to 12 parts of nano silicon dioxide, 3 to 15 parts of nano calcium carbonate, 1 to 5 parts of ammonium octamolybdate, 2 to 5 parts of zincnaphthenate, 1 to 4 parts of calcium stearate, 2 to 5 parts of 1-phenyl-3-methyl-5-pyrazolone, and 2 to 7 parts of sorbitol. The provided heatproof flame-retardant locomotive cable has the advantagesof excellent heatproof and flame-retardant properties, and high strength.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a heat-resistant and flame-retardant locomotive cable. Background technique [0002] As the link connecting various electrical equipment, cables play a pivotal role in the normal operation of the equipment. The rolling stock cables widely used in subways and urban rail vehicles often need to have properties such as high temperature resistance, oil resistance, softness, heat resistance and flame retardancy. However, the heat resistance and flame retardancy of the existing locomotive cables are not very good. When used in the narrow space of the locomotive, there are defects of poor heat resistance and flame retardancy, which need to be modified. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a heat-resistant and flame-retardant locomotive cable, which has excellent heat resistance, flame retardancy, ...
