preparation example Construction

[0032] The embodiment of the present invention also provides a preparation method of a composite material used for the outer sheath of a locomotive cable, which includes: mixing the components in the raw materials. The obtained outer sheath has very excellent flame retardancy and high and low temperature resistance performance after being used in cables.

[0033] Further, the mixing temperature is 130-170° C., and the mixing time is 5-15 minutes; preferably, the mixing temperature is 140-160° C., and the mixing time is 7-9 minutes. It is advisable to control the mixing temperature and mixing time within the above range, so that all components can be fully mixed and uniform, and the flame retardancy and high and low temperature resistance of the material can be guaranteed.

[0034]The embodiment of the present invention also provides a cable outer sheath, which is prepared from the above-mentioned composite material. The preparation method of the cable outer sheath belongs to ...

Abstract

The invention discloses a composite material for a locomotive cable outer sheath, a preparation method of the composite material, the cable outer sheath and a locomotive cable, and relates to the technical field of industrial cables. The composite material for the locomotive cable outer sheath is prepared from the following raw materials in parts by weight: 12 to 23 parts of ethylene-vinyl acetatecopolymer resin, 2 to 7 parts of polyolefin elastomer resin, 13-25 parts of linear low-density polyethylene resin, 1-4 parts of high-density polyethylene resin, 3-10 parts of maleic anhydride graftedPOE, 0.1-0.8 part of an antioxidant, 0.1-0.8 part of an irradiation crosslinking agent, 1-13 parts of an organophosphorus flame retardant, 20-50 parts of calcium magnesium carbonate and 1-7 parts ofan organosilicon flame retardant. The material can be endowed with good flame retardant property and high and low temperature resistance. The preparation method takes materials in the formula as raw materials. The material of the outer sheath of the locomotive cable is the composite material for the outer sheath of the locomotive cable, and the outer sheath can work at ultralow temperature and ultrahigh temperature and has good flame retardant property.

Description

technical field [0001] The invention relates to the technical field of industrial cables, and in particular to a composite material used for the outer sheath of a locomotive cable and a preparation method thereof, the outer sheath of the cable and the locomotive cable. Background technique [0002] The national railway system closely follows the national development lines, and continuously improves the comfort, high-speed, and safety of high-speed railways to meet passengers' requirements for high-speed railways. Therefore, it is necessary to require rolling stock cables to continuously and stably transmit power or signals during the high-speed operation of the locomotive, and to have properties such as halogen-free, low smoke, ultra-high and low temperature resistance, environmental protection, oil resistance, and high flame retardancy. The existing rolling stock cables cannot fully meet the above requirements, especially the combustion performance and ultra-high and low te...
