The cable material is prepared from 12-15 parts by weight of friction powder made of cashew nut shell oil, 13-15 parts by weight of barium metaphosphate, 7-8 parts by weight of alumina, 10-13 parts by weight of basalt fibres, 4-5 parts by weight of castor oil, 2-3 parts by weight of dioctyl terephthalate, 3-4 parts by weight of an antioxidant 1035, 3-4 parts by weight of triallyl isocyanurate, 55-65 parts by weight of butadiene-acrylonitrile rubber, 55-60 parts by weight of chloroprene rubber, 2-3 parts by weight of paraffin oil, 3-4 parts by weight of zinc stearate, 55-70 parts by weight of natural rubber, 30-40 parts by weight of hollow glass micro beads, 1-1.3 parts by weight of a silane coupling agent kh550, 12-16 parts by weight of epoxy resin E44, 0.06-0.1 part by weight of diethylenetriamine, 0.1-0.2 part by weight of an accelerant NS, 2.6-3 parts by weight of a silane coupling agent kh570 and a proper amount of distilled water. The cable material is good in fireproofing performance, flame retardant, not liable to combust, low in smoke, long in service lifetime, capable of saving resources and good in practicability.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-temperature-resistant, low-smoke, flame-retardant rubber cable material. Background technique [0002] As the name implies, hollow glass microspheres are hollow glass microspheres with different hollowness and density. In most cases, adding hollow glass microspheres to polymers can significantly reduce material costs, improve the processing flow properties of high-viscosity materials, endow products with better appearance, and improve the stiffness and even strength of materials. Under certain conditions, it can also improve the wear resistance and impact resistance of the material to a certain extent, and can also give the product good heat insulation, sound insulation and other properties. With the continuous and rapid development of China's economy, cables have been widely used in various industries, and it is the second largest industry in China after the auto...

Problems solved by technology

With the continuous and rapid development of China's economy, cables have been widely used in various industries, and it is the second largest industry in China after the automobile industry. , leading to the damage or loss of the original performance of the cable rubber surface, especially when used in an environment with long-term high temperature and complex geological conditions, its wear-resistant collision, temperature resistance, medium resistance, aging resistance, and flame retardancy cannot meet the requirements. Frequent electrical accidents, and with the further improvement of the country's electrical safety requirements, the quality of cables will be higher and higher

Cable is the carrier of power transmission, and its use scenarios are very broad, which also makes the requirements for cable performance different in different application scenarios, especially in some low-temperature environments, the existing cables face many problems during use , for example, in the process of dragging and bending, the cable is easily damaged, and in the low temperature environment, the outer sheath of the cable is easily broken and damaged, which needs to be solved urgently
