Abstract

The invention discloses a low-hardness 125 DEG C irradiation-crosslinking halogen-free low-smoke flame-retardant insulation material for a new-energy vehicle wire. The low-hardness 125 DEG C irradiation-crosslinking halogen-free low-smoke flame-retardant insulation material is prepared from, by weight, 15-20 parts of ethylene propylene diene monomer, 50-60 parts of ethylene acetic ether, 15-20 parts of polyolefin elastomer, 10-15 parts of compatilizer, 2.5 parts of flame retardant 125 and crosslinking agent triallyl isocyanurate, 3 parts of silicone powder, 2 parts of PE wax, 1 part of gamma-methyl propyl trimethoxy silane, 1 part of polysiloxane, 1 part of tetra-[beta-(3.5-ditert-butyl-4-hydroxycyclohexyl phenyl) propionic acid] pentaerythritol ester and 1 part of disteaxyl thiodipropionate. The cable material is good in flame retardant effect, low in smoke, free of halogen, capable of avoiding 'secondary disaster', safe and environmentally friendly, has the good mechanical property,electrical insulation property, oil resistance, wear resisting property, heat resisting property and ageing resistance, and is broad in application prospect.

Description

technical field [0001] The invention relates to the field of cable materials and their manufacture, in particular to a low-hardness 125°C radiation-crosslinked halogen-free low-smoke flame-retardant insulating material for new energy automobile wires and a preparation method thereof. Background technique [0002] The automobile manufacturing industry has become a pillar industry of my country's national economy, driving the development of a large number of supporting industries. Automobile wires are important accessories to improve the technical content of automobiles, and higher requirements are constantly being put forward for the cable materials used to make automobile wires. At present, the development characteristics of low-voltage automotive wires in recent years can be summarized by simply using small wire diameter, radiation cross-linked polyolefin thin-wall insulation, and high reliability. [0003] Currently on the market, automotive wires are mainly cable materia...
