Embodiment Construction

[0018] A flame-retardant and heat-resistant cable material for railway rolling stock, made of the following raw materials in weight (kg): low-density polyethylene 86, tetrafluoroethylene-hexafluoropropylene copolymer 44, 2,2,4-trimethyl Base-1,3-pentanediol diisobutyrate 15, waste glass powder 17, brucite powder 13, oleic acid diethanolamide borate 4.5, antimony trisulfide 6, erucamide 4, oxidized polyethylene Wax 3, trimethylolpropane trioleate 2, composite flame retardant 19, dibasic lead phosphite 2.5, cerium isooctanoate 1.5, pentachlorobiphenyl 1, methyl p-tert-butylbenzoate 2.5;

[0019] The preparation method of described composite flame retardant is as follows:

[0020] (1) Take colemanite, montmorillonite and magnesium molybdate in a mass ratio of 4:3:1, mix them uniformly, pulverize, pass through a 120 mesh sieve, and then ball mill at 600r / min for 1h;

[0021] (2) Mix the powder obtained by the above ball milling with water to prepare a suspension with a concentrat...

Abstract

The invention discloses a locomotive flame retardant and heat resistant cable material and a preparation method thereof. The locomotive flame retardant and heat resistant cable material is prepared from the following raw materials in parts by weight: 78-94 parts of LDPE, 33-51 parts of tetrafluoroethylene-hexafluoropropylene copolymer, 11-17 parts of 2,2,4-trimethyl-1,3-pentanediol diisobutyrate, 16-22 parts of waste glass powder, 10-15 parts of brucite powder, 3-6 parts of diglycolamide oleate borate, 4-8 parts of antimony trisulfide, 3.5-5 parts of erucyl amide, 2-4 parts of oxidized polyethlene wax, 1.5-2.5 parts of TMPTO, 17-23 parts of a composite flame retardant, 2-3 parts of lead oxide phosphite hydrate, 1-2 parts of cerium isooctanoate, 1-2 parts of pentachlorodiphenyl and 2-3 parts of methyl 4-tert-butylbenzoate. The prepared cable material is highly flame retardant and heat resistant, has the flame retardant effect during the use, can work for a long time under a high temperature condition, is prevented from softening and deforming, is good in use effect and long in service life, and meets the demand of high performance of locomotive cables.

Description

technical field [0001] The invention relates to a cable material, in particular to a flame-retardant and heat-resistant cable material for railway locomotives and a preparation method thereof. Background technique [0002] With the rapid development of the economy, wires and cables have been widely used in the railway rolling stock industry. In recent years, electrical fire accidents of railway locomotives 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 railway locomotives on the market generally have the disadvantage of poor heat resistance, which leads to their short service life and cannot meet the market demand. Therefore, it is ...
