Irradiation-resistant anti-aging sheath material for communication wire harness, and preparation method of irradiation-resistant anti-aging sheath material

Abstract

The invention discloses an irradiation-resistant anti-aging sheath material for a communication wire harness, and a preparation method thereof. The irradiation-resistant anti-aging sheath material for the communication wire harness is prepared from the following raw materials in parts by weight: 34 to 48 parts of polytetrafluoroethylene, 14 to 22 parts of polyetherimide, 11 to 19 parts of polyphenylene sulfone, 5 to 10 parts of light calcined powder, 5 to 10 parts of nano barium sulphate, 12 to 18 parts of dibutyl phthalate, 2 to 3 parts of calcium ascorbate, 7 to 14 parts of a ceramic polishing waste material, 5 to 8 parts of low-molecular-weight polyisobutylene, 6 to 12 parts of calcium silicate slag tail, 5 to 10 parts of baddeleyite, 3 to 4 parts of poly(ethylene glycol) monooleate, 4 to 6 parts of behenamide, 2 to 3 parts of calcium isooctanoate, 1 to 2 parts of zinc isoocatanoate, and 4 to 5 parts of antimony pentasulfide. According to the irradiation-resistant anti-aging sheath material for the communication wire harness, and the preparation method thereof, irradiation-resistant materials, such as polyetherimide and polyphenylene sulfone are added into polytetrafluoroethylene for blending and modifying, and meanwhile, a suitable amount of inorganic fillers, such as nano barium sulphate, the calcium silicate slag tail, baddeleyite and antimony pentasulfide, are added, so that the irradiation resistance of the sheath material can be improved, and the anti-aging performance, the heat stability and the corrosion resistance of the sheath material can also be improved.

Description

Technical field [0001] The invention relates to a radiation-resistant and anti-aging sheath material for communication wiring harnesses and a preparation method thereof, and belongs to the field of polymer materials. Background technique [0002] The communication harness is generally composed of wires, insulating sheath materials, wiring terminals and wrapping materials. Among them, the sheath material is an important part of the communication harness, which not only plays the role of insulation protection, but also plays the role of flame retardant, anti-corrosion, and waterproof. The quality of the sheath material directly affects the quality and service life of the communication harness. At present, there are many types of communication harness sheath materials on the market with different performances, but the sheath materials used for communication harnesses still have the disadvantages of poor radiation resistance and poor aging resistance, which affects the service life ...
