Embodiment Construction

[0018] An anti-cracking cable material for railway rolling stock, made of the following raw materials in weight (kg): linear low density polyethylene 85, poly-p-phenylene terephthalamide 25, basalt fiber 26, acetyl citrate three N-butyl ester 18, composite flame retardant 20, trimethylol propane cocoate 5, isostearyl laurate 4, dibutyltin dilaurate 3, monophenylene diisooctyl phosphite 2.5, distearyl Acid Hydroxy Aluminum 3, Potassium Titanate Whisker 15, Cork Powder 12, Resorcinol Monobenzoate 2.5, Nickel Dibutyl Dithiocarbamate 1;

[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 an 80-mesh sieve, and then ball mill at 600r / min for 1h;

[0021] (2) Add water and stir the powder obtained by the above ball mill to prepare a suspension with a concentration of 40g / L, and then add a certain volume of 1mol / ...

Abstract

The invention discloses a locomotive cracking resistant cable material and a preparation method thereof. The locomotive cracking resistant cable material is prepared from the following raw materials in parts by weight: 78-94 parts of LLDPE, 20-30 parts of PPTA, 22-28 parts of basalt fibre, 15-20 parts of ATBC, 18-24 parts of a composite flame retardant, 4-6 parts of trimethylolpropane glyceryl cocoate, 3-5 parts of dodecanoic acid, 3-4 parts of dibutyltin dilaurate, 2-3 parts of PDOP, 2-3 parts of aluminium hydroxy distearate, 13-17 parts of potassium titanate whisker, 10-15 parts of cork powder, 2-3 parts of resorcinol monobenzoate and 1-2 parts of nickel dibutyldithiocarbamate. The cable material is excellent in crack resistance, cannot easily crack under the long-term actions of low temperature and impact force, and the like, and is high in mechanical strength, better in electrical insulating property and flame retardant property, organically integrates the electrical insulating property, flame retardant property, mechanical performance and cracking resistance, and is easy to manufacture, wide in material selecting range, lower in cost and good in use performance.

Description

technical field [0001] The invention relates to a cable material, in particular to an anti-cracking 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 currently on the market generally have the disadvantage of poor crack resistance, which leads to their short service life and cannot meet market demand. Therefore, it is urgent to cha...
