Impact-resistant and tear-resistant sheath material for automobile door wire harness and preparation method for impact-resistant and tear-resistant sheath material

Abstract

The invention discloses an impact-resistant and tear-resistant sheath material for an automobile door wire harness and a preparation method for the impact-resistant and tear-resistant sheath material. The impact-resistant and tear-resistant sheath material is prepared from the following raw materials in parts by weight: 29 to 37 parts of syndiotactic polypropylene, 22 to 34 parts of an ethylene-1-octene copolymer, 16 to 24 parts of polyethylene glycol terephthalate-1,4-cyclohexanedimethanol terephthalate, 7 to 11 parts of waste polished tiles, 8 to 14 parts of hydroxyl-terminated polybutadiene, 4 to 8 parts of hollow silica nanospheres, 6 to 10 parts of zircon powder, 8 to 12 parts of china stone tailings, 10 to 15 parts of dipropylene glycol dibenzoate, 1 to 2 parts of zinc diricinoleate, 1 to 2 parts of calcium ricinoleate, 5 to 10 parts of converter steel slag, 4 to 7 parts of nanometer graphene oxide, 3 to 6 parts of long-chain-alkyl silicone oil and 2 to 5 parts of montan wax. According to the impact-resistant and tear-resistant sheath material and the preparation method thereof, the advantages of the macromolecular raw materials such as the syndiotactic polypropylene and the ethylene-1-octene copolymer are combined, and meanwhile, an organic filler such as the nanometer graphene oxide is added, so that the performance of a conventional polypropylene sheath material is improved, and the impact-resistant and tear-resistant sheath material is endowed with stronger tear strength and impact strength, also has the characteristics of high aging resistance, heat resistance and weather resistance and the like, and can be widely used for manufacturing an automobile tail wire harness sheath.

Description

technical field [0001] The invention relates to an impact-resistant and tear-resistant sheath material for automobile door wire harnesses 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 wire harness sheathin...
