Abstract

The invention discloses a 125 DEG C-irradiation crosslinked halogen-free low-smoke flame-retardant insulating material for a new-energy vehicle wire. The 125 DEG C-irradiation crosslinked halogen-freelow-smoke flame-retardant insulating material is prepared from the following raw materials in parts by weight: 15-20 parts of metallocene linear low-density polyethylene, 50-60 parts of ethyl vinyl acetate, 15-25 parts of polyolefin elastomer, 10-15 parts of compatibilizer, 125 parts of flame retardant, 2.5 parts of crosslinking aid (triallyl isocyanurate), 3 parts of silicone powder, 2 parts ofPE (polyethylene) wax, 1 part of gamma-methacryloyloxypropyltrimethoxysilane, 1 part of polysiloxane, 1 part of methyl silicone oil, 1 part of tetra[beta-(3,5-ditertbutyl-4-hydroxyphenyl)propanoic acid]pentaerythritol ester and 1 part of disteaxyl thiodipropionate. The 125 DEG C-irradiation crosslinked halogen-free low-smoke flame-retardant insulating material disclosed by the invention has the advantages of good flame-retardant effect, low-smoke and halogen-free effects, no cause of secondary disaster, safe and environment-friendly effects, good mechanical property, electric insulating property, oil resistance, wear resistance, heat resistance and ageing resistance and wide application prospect.

Description

technical field [0001] The invention relates to the field of cable material and its manufacture, in particular to a 125°C irradiation cross-linking halogen-free low-smoke flame-retardant insulating material for new energy automobile wires and a preparation method thereof. Background technique [0002] Currently on the market, automotive wires are mainly cable materials based on polyvinyl chloride and low-halogen irradiation cross-linking materials. Although polyvinyl chloride-based cable materials have the advantages of low price, good flame retardancy, and good processability, they and low-halogen irradiation crosslinking materials both contain halogens, which are a threat to human health and the natural environment. With the development of society, it is a trend that low-smoke and halogen-free automobile wires gradually replace halogen-containing automobile wires. In addition, the environment where the automobile wire is located is generally oily, which will generate fric...
