Locomotive flame retardant and heat resistant cable material and preparation method thereof

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 ...

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 heat resistance, which leads to their short service life and cannot meet market demand.
