The invention discloses a high-temperature-resistant and wear-resistant nylon cable material for a coal mine cable and a preparation method of the high-temperature-resistant and wear-resistant nylon cable material. The high-temperature-resistant and wear-resistant nylon cable material is prepared from the following raw materials in parts by weight: 55 to 75 parts of nylon46, 30 to 50 parts of ethylene-chlorotrifluor ethylene copolymer, 18 to 36 parts of polyarylether ether nitrile, 8 to 16 parts of pentaerythritol distearate, 4 to 8 parts of ethylene bis oleamide, 13 to 19 parts of Di(2-ehtylhexyl)4,5-epoxy tetrahydrophthalate, 15 to 20 parts of zirconium nitride, 10 to 15 parts of N-cyclohexyl para toluene sulfonamide, 14 to 22 parts of vermiculite, 5 to 10 parts of polytetrafluoroethylene micropowder wax, 18 to 26 parts of waste silica brick, 4 to 7 parts of cuprous bromide, 10 to 15 parts of crystalline flake graphite powder and 5 to 10 parts of dilinoleic acid. The cable material has improved performance of a traditional nylon cable material, has excellent high temperature resistance and wear resistance, especially has high wear resistance and a low friction coefficient in a high temperature condition, and has greatly-prolonged service life.
Description
technical field [0001] The invention relates to a high-temperature and wear-resistant nylon cable material for coal mine cables and a preparation method thereof, belonging to the technical field of cable material manufacturing. Background technique [0002] Nylon, scientific name polyamide, is a general term for thermoplastic resins containing repeating amide groups -[-NHCO-]- on the main molecular chain. Nylon has the characteristics of many varieties, large output and wide application, and is one of the five major engineering plastics. Because of its high mechanical strength, high softening point, heat resistance, low friction coefficient, wear resistance, self-lubrication, shock absorption and noise reduction, oil resistance, weak acid resistance, alkali resistance and general solvents; good electrical insulation, It has the advantages of self-extinguishing, non-toxic, odorless, and good weather resistance, and is widely used in the production of cables and cables. With...
