Locomotive cracking resistant cable material and preparation method thereof

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...

Problems solved by technology

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 still generally have the disadvantage of poor crack resistance, which leads to their short service life and cannot meet the market demand.
