Irradiation cross-linked halogen-free flame-retardant polyolefin material for new energy automobile wire as well as preparation method and application of irradiation cross-linked halogen-free flame-retardant polyolefin material

Abstract

The invention discloses an irradiation crosslinking halogen-free flame-retardant polyolefin material for new energy automobile wires and a preparation method and application thereof. The irradiation crosslinking halogen-free flame-retardant polyolefin material comprises the following raw materials: base resin, a compatilizer, a halogen-free flame retardant, an antioxidant and an assistant crosslinker, the base resin comprises SEBS, polyphenyl ether, linear low-density polyethylene resin, an ethylene-vinyl acetate copolymer, vinyl silicone rubber and ethylene propylene diene monomer, and the SEBS is oil-filled SEBS; during preparation, the polyphenyl ether master batch and the flame-retardant master batch can be respectively prepared firstly and then are mixed and extruded with other raw materials; the material can meet the requirements of light weight, water resistance, oil resistance and solvent resistance at the same time, and can be used for producing large-square (conductor area is greater than or equal to 6.0 mm < 2 >) high-voltage wires in new energy automobiles.

Description

technical field [0001] The invention belongs to the field of new energy automobile cables, and in particular relates to a radiation crosslinked halogen-free flame-retardant polyolefin material for new energy automobile cables, a preparation method and application thereof. Background technique [0002] With the demand for environmental protection and other aspects, countries around the world are basically advocating relatively environmentally friendly new energy industries, such as new energy vehicles that have gradually become popular. At present, although new energy vehicles are developing well, as consumers continue to improve their quality requirements, some shortcomings are still exposed, such as new energy vehicle lines, the proportion of existing vehicle lines is too large, and it is difficult to meet the lightweight The demand for new energy vehicles is relatively large, and there is still a large square (conductor area ≥ 6.0mm 2 ) High-voltage wires in the car (high...

AI Technical Summary

Problems solved by technology

At present, although new energy vehicles are developing well, as consumers continue to improve their quality requirements, some shortcomings are still exposed, such as new energy vehicle lines, the proportion of existing vehicle lines is too large, and it is difficult to meet the lightweight The demand for new energy vehicles is relatively large, and there is still a large square (conductor area ≥ 6.0mm 2 ) High-voltage wires in the car (high voltage refers to the voltage of AC 600-1000V / DC 900-1500V) and the demand trend of increasing proportion

In addition, the high-temperature-resistant flexible cables of existing new energy vehicles are difficult to meet the requirements of water resistance, oil resistance and solvent resistance.
