Abstract

The invention relates to the technical field of cables, and discloses an efficient flame-retardant wear-resistant subway cable and a preparation method thereof. The efficient flame-retardant wear-resistant subway cable comprises the following raw materials in parts by weight: 20-40 parts of silicone rubber, 5-15 parts of ethylene propylene diene monomer, 3-8 parts of butyl rubber, 3-10 parts of polyurethane, 3-4 parts of acetyl trioctyl citrate, 10-20 parts of modified aluminum oxide, 10-15 parts of kaolin, 10-15 parts of micro-encapsulation red phosphorus, 5-10 parts of zinc borate, 2-6 partsof 3-aminopropyltriethoxysilane, 1-2 parts of an accelerant, 2-4 parts of a Ca / Zn composite stabilizer, 1-3 parts of an anti-ageing agent, 3-7 parts of silicone powder and a cable body. The modifiedaluminum oxide is dispersed uniformly in a cable material, the properties are synergistic, the strength and wear resistance of the cable material are further improved, the kaolin and the silicone powder cooperate with each other, and the high temperature resistance, impact resistance, wear resistance and machinability of the efficient flame-retardant wear-resistant subway cable can be improved further.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-efficiency flame-retardant and wear-resistant subway cable and a preparation method thereof. Background technique [0002] Subway is a form of railway transportation, which refers to the urban rail transit system that mainly operates underground, that is, the abbreviation of "underground railway" or "subway" (Subway, tube, underground). Many such systems are designed to match the built environment. And considering the construction and operating costs, it may be converted into a ground or elevated section outside the city center. The subway is a proprietary, high-density, high-capacity urban rail transit system (Metro) covering various underground and above-ground roads in urban areas. , China Taiwan subway called "MRT". [0003] Compared with other means of transportation in the city, in addition to avoiding urban ground congestion and making full use of space, the subway ...
