Example Embodiment

[0015] A high-strength cable material for urban rail transit is made from the following weight (kg) raw materials: SG-2 type PVC resin 66, ethylene-chlorotrifluoroethylene copolymer 32, liquid polyisoprene rubber 17, alkali Magnesium sulfate whisker 12, pentaerythritol tetrabenzoate 11, bisphenol A bis(diphenyl phosphate) 8, di-n-butyl sebacate 12, activated alumina 16, fluorite powder 13, hexafluoroacetylacetone Calcium 2.5, isohexadecyl stearate 4, butyloxazole-2,4-dione 2.5, lead salicylate 1.5, ethyl gallate 1, composite flame retardant 14;

[0016] The preparation method of the composite flame retardant is as follows:

[0017] (1) Weigh palygorskite, attapulgite and barium metaborate in a ratio of 6:5:3 by mass, mix well, pulverize, pass through a 100-mesh sieve, and then ball mill at 700r / min for 0.5h;

[0018] (2) adding water to the powder obtained by the above-mentioned ball milling and stirring to prepare a suspension with a concentration of 55g / L, and then adding a...

Abstract

The invention discloses a high-strength cable material for urban rail transport and a preparation method thereof. The high-strength cable material is prepared from the following raw materials, by weight, 51-73 parts of SG-2 type PVC resin, 25-38 parts of an ethene-trifluorochloroethene copolymer, 12-21 parts of liquid polyisoprene rubber, 10-15 parts of basic magnesium sulfate whiskers, 7-13 parts of pentaerythritol tetrabenzoate, 5-10 parts of tetraphenly bispheol A diphosphate, 10-15 parts of Di-n-butyl sebacate, 14-18 parts of activated aluminium oxide, 10-15 parts of fluorite powder, 2-3 parts of calcium hexafluoroacetylacetonate, 3-5 parts of isocetyl stearate, 2-3 parts of butyloxazole-2,4-dione, 1-2 parts of lead salicylate, 1-2 parts of ethyl gallate and 12-16 parts of a composite flame retardant. The cable material provided by the invention has excellent physical and mechanical properties and can be used to raise strength of cables, effectively reduce mechanical damage and prolong service life of cables. The cable material also has excellent wear resistance, corrosion resistance, heat aging resistance and weather fastness.

Description

technical field [0001] The invention relates to a cable material, in particular to a high-strength 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, the cable materials for urban rail transit currently on the market generally have the disadvantage of low mechanical strength, which leads to their short service life and cannot meet market demand. Therefore, it is urgent to change t...
