Heatproof corrosion-resistant cable material for urban rail transport and preparation method thereof

Abstract

The invention discloses a heatproof corrosion-resistant cable material for urban rail transport and a preparation method thereof. The heatproof corrosion-resistant cable material is prepared from the following raw materials, by weight, 38-46 parts of teflon, 24-33 parts of a liquid crystal polymer, 16-22 parts of polyarylsulfone, 10-15 parts of a nano-zeolite molecular sieve, 6-12 parts of hexaphenoxy cyclotriphosphazene, 5-10 parts of diethylene glycol dibenzoate, 3-6 parts of microcrystalline wax, 8-16 parts of hollow glass microspheres, 14-18 parts of a composite flame retardant, 4-9 parts of melamine cyanurate, 2-3 parts of tri(mercaptoacetic acid n-butyl ester)antimony, 2-3 parts of 2-octyldodecanol, 10-15 parts of diallyl phthalate, 2-3 parts of Stearoylbenzoylmethane and 1-2 parts of 6-ethoxy-2,2,4-trimethyl-1,2-dihydro-quinoline. The cable material has good heat resistance, and the heat resistance grade reaches 160 DEG C. In addition, the cable material has excellent corrosion resistance, is especially resistant to corrosive mediums such as acid, alkali, salt, oil and the like, has good wear resistance, weather ageing resistance, flame resistance and the like, and can completely meet requirements of performance when used under conditions of high-temperature corrosive mediums.

Description

technical field [0001] The invention relates to a cable material, in particular to a heat-resistant and corrosion-resistant cable material for urban rail transit and a preparation method thereof. Background technique [0002] With the rapid development of the economy, wires and cables have been widely used in the urban rail transit industry. In recent years, electrical fire accidents in urban rail transit have occurred frequently, and the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. When the cable burns, it releases a large amount of smoke and toxic and corrosive gas, which seriously hinders people's safe evacuation and fire fighting work, causing serious loss of life and property. At the same time, cable materials for urban rail transit currently on the market generally have the disadvantages of poor heat resistance and corrosion resistance, resulting in short service life and unable to meet market deman...
