Abstract

The invention discloses a high-temperature-irradiation-resistant halogen-free flame-retardant automobile wire material and a preparation method thereof. The high-temperature-irradiation-resistant halogen-free flame-retardant automobile wire material adopts high-density polyethylene, linear low-density ethylene, a thermoplastic polyurethane elastomer, an olefin block copolymer and an ethylene-butyl acrylate copolymer with different melt indexes as resin matrixes; a halogen-free flame retardant composed of an intumescent flame retardant, magnesium hydroxide and zinc borate is added into the resin matrixes, and a functional filler, an antioxidant, a lubricant and a crosslinking sensitizer are combined; and thus, the obtained automobile wire material can satisfy the required softness and wear resistance and also ensure the thermal overload property of the product. Besides, the wire material has the advantages of favorable flame retardancy, low smoke and no halogen, and conforms to the requirements for environmental protection. The preparation method of the product has the advantages of simple technique and low cost, and is easy to operate and suitable for popularization and application.

Description

technical field [0001] The invention relates to a flame-retardant composite and a preparation method thereof, in particular to a high-temperature radiation-resistant halogen-free flame-retardant automotive wire and a preparation method thereof, belonging to the technical field of polymer composite materials. Background technique [0002] As we all know, automotive wiring harness materials need to have performance requirements such as flame retardancy, wear resistance, and oil resistance. According to different environments and locations of use, automotive cables can be divided into various temperature grades of 80°C, 105°C, 125°C and 150°C. At the same time, it has the characteristics of wear resistance and flame retardancy. Currently, low-smoke and low-halogen materials are used in the market. Most of the flame retardants used in low-smoke and low-halogen products are brominated flame retardants, and their combustion will produce a large amount of smoke and irritating gase...
