Abstract

The invention discloses a heat-resistant rubber cable sheath material which is prepared from the following raw materials in parts by weight: 3-4 parts of magnesium stearate, 12-14 parts of mica powder, 8-11 parts of aluminum nitride, 4-6 parts of nano silver fiber, 5-6 parts of urea, 55-60 parts of chloroprene rubber, 2-3 parts of liquid paraffin, 10-13 parts of isoprene rubber, 46-55 parts of cis-1,4-polybutadiene rubber, 55-70 parts of natural rubber, 30-40 parts of hollow glass microsphere, 0.3-0.4 part of antioxidant BHT, 2-3 parts of sulfur, 2-3 parts of organobentonite, 1-1.3 parts of silane coupling agent kh550, 12-16 parts of epoxy resin E44, 0.06-0.1 part of diethylenetriamine, 0.1-0.2 part of accelerator DA, 2.6-3 parts of silane coupling agent kh570 and a right amount of distilled water. The rubber cable sheath has the characteristics of excellent heat resistance, excellent oil resistance, no combustion spreading, chemical corrosion resistance and the like, prolongs the service life of the cable, saves the resources and lowers the cost.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a heat-resistant rubber cable sheathing 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 automobile industry. , leading to...

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
