Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength and high-toughness heat-insulating cable. Background technique [0002] Natural rubber is a natural polymer compound with a polyisoprene content of more than 90%. Because of its good elasticity, plasticity, strength and insulation properties, it is widely used in various fields of industrial production, such as: wires , Cables, conveyor belts, rubber hoses, various rubber products used in the electronics and electrical industries, as well as rubber products used in automobiles, airplanes, and ships. [0003] Natural rubber also has some disadvantages, such as high cost, low strength, insufficient toughness, etc. Therefore, different ingredients are often added in industrial production to meet diverse needs. In the field of cable processing, high strength and high toughness are the basic requirements for cables. At the same time, when cables are used in certain hig...
