Locomotive fluoroplastic cable material and preparation method thereof

Abstract

The invention discloses a locomotive fluoroplastic cable material and a preparation method thereof. The locomotive fluoroplastic cable material is prepared from the following raw materials in parts by weight: 57-81 parts of FEP resin, 22-36 parts of ethylene-octylene copolymer, 8-14 parts of propylene carbonate, 17-23 parts of hydrated magnesium silicate ultrafine powder, 14-18 parts of lithium feldspar powder, 10-15 parts of aluminum dihydrogen tripolyphosphate, 12-17 parts of tri-ethylene glycol BNDB, 7-11 parts of ethyl 4-dimethylaminobenzoate, 13-19 parts of a composite flame retardant, 1.5-2.5 parts of di-n-octyltin moleate polymer, 2-3 parts of PGFE, 5-8 parts of liquid paraffin, 2-3 parts of 1,4-bis(methoxymethyl)-benzene and 1-2 parts of 2-2 stearate pentaerythritol phosphate. The prepared cable material is excellent in overall performance, has the excellent performances of higher mechanical strength, excellent electrical insulating property, fire resistance, heat resistance, abrasive resistance, chemical corrosion resistance, heat stability, gaining resistance, and the like, and is wide in application prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to a fluorine plastic 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 disadvantages of low strength, poor chemical corrosion resistance, heat resistance, and poor wear resistance, resulting in short service li...

AI Technical Summary

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 disadvantages of low strength, poor chemical corrosion resistance, heat resistance, and poor wear resistance, resulting in short service life and unable to meet market demand.
