Abstract

The invention discloses a creep-resistant sheath material for an automobile tail wire harness and a preparation method for the creep-resistant sheath material. The creep-resistant sheath material is prepared from the following raw materials in parts by weight: 37 to 49 parts of polyphenyl ether, 5 to 10 parts of high-magnesium phosphate tailings, 16 to 24 parts of phenoxy resin, 12 to 19 parts of poly(1-butene), 10 to 15 parts of polyamideimide, 3 to 6 parts of ethylene bis lauramide, 8 to 12 parts of waste bone china, 9 to 16 parts of epoxy linseed oil, 5 to 10 parts of carbon whiskers, 5 to 10 parts of lithium china stones, 4 to 8 parts of low molecular weight polypropylene, 10 to 15 parts of dimethyglycol phthalate, 4 to 6 parts of zinc dioleate and 7 to 9 parts of calcium zirconate. The creep-resistant sheath material for the automobile tail wire harness contains the raw materials such as the polyphenyl ether, the phenoxy resin, the poly(1-butene), the polyamideimide, the carbon whiskers and the calcium zirconate, and the prepared material has high creep resistance, flexibility, high temperature resistance and aging resistance.

Description

technical field [0001] The invention relates to an anti-creep sheath material for an automobile rear harness and a preparation method thereof, belonging to the field of polymer materials. Background technique [0002] With the rapid development of automotive electronics technology, a large number of wiring harness products are used in automobiles, which play an important role in the safety and reliability of automobiles. Automotive wiring harnesses generally consist of wires, insulating sheath materials, terminal blocks and wrapping materials. Among them, the sheath material is an important part of the automobile wiring harness, which not only plays the role of insulation protection, but also plays the role of flame retardancy, corrosion resistance and waterproof. The quality of the sheath material directly affects the quality and service life of the automotive wiring harness. At present, there are many kinds of automotive wiring harness sheathing materials in the market w...
