High-wearability insulating cable material and preparation method thereof

Abstract

The invention discloses a high-wearability insulating cable material and a preparation method thereof. The high-wearability insulating cable material is prepared from the following raw materials in parts by weight: 70 to 90 parts of polyurethane rubber, 15 to 20 parts of polytetrafluoroethylene, 10 to 15 parts of nylon 6, 10 to 15 parts of polypropylene glycol adipate, 5 to 10 parts of dipropylene glycol dibenzoate, 5 to 10 parts of trel-butylphenyl diphenyl phosphate, 7 to 13 parts of antimonous oxide, 5 to 10 parts of decabromodiphenylethane, 4 to 8 parts of zinc borate, 2 to 3 parts of tert-butyl peroxybenzoate, 1.5 to 2 parts of zinc oxide, 2 to 3 parts of stearic acid, 3 to 6 parts of chlorcosane, 1 to 2 parts of accelerant ZDMC (Zinc Dimethyldithiocarbamate), 1 to 2 parts of accelerant CZ (N-cyclohexylbenzothiazole-2-sulphenamide), 15 to 20 parts of fumed silica, 10 to 15 parts of attapulgite nanoocomposites, 5 to 10 parts of nano zeolite, 10 to 15 parts of precipitated barium sulphate, 1.5 to 2.5 parts of antioxidant 1010, 2 to 3 parts of anti-aging agent TPPD (N-(p-toluene-sulphonylamido-N'-phenylene diamine)), and 3 to 6 parts of composite filler. The cable material is outstanding in wearability, particularly, the wearability is always several times and even dozen times that of the common electrical material under a terrible working condition in the presence of water, oil and other wetting medias; the cable material is also remarkable in heat resistance, flame resistance, ageing resistance, oil resistance, warping strength, impact resistance and tear resistance.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a high wear-resistant insulating cable material and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy, the demand for wire and cable has risen sharply, prompting a rapid increase in the use of cable materials. At present, the sheath materials of wire and cable mainly include PE, PVC and so on. However, due to poor wear resistance, these common sheath materials cannot be used for wires and cables in various harsh environments. Therefore, it is necessary to develop a cable material with excellent wear resistance to meet the performance requirements of modern wire and cable. Contents of the invention [0003] The object of the present invention is to provide a high wear-resistant insulating cable material with excellent comprehensive performance and a preparation method thereof for t...
