Problems solved by technology

Although there are many kinds of cables on the market, the performance of the sheath material of most cables is still not ideal. During the use of the cable, there are defects such as unsatisfactory high temperature resistance, low strength, and poor impact resistance. Reduced cable life, increased economic pressure, and potential safety hazards

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high temperature resistant natural rubber cable sheath material. Background technique [0002] With the development of my country's petrochemical, communication, transportation, construction, electric power and other industries, the demand for cables in power plants, substations, smelting and petrochemical industries has been extremely high in recent years, and at the same time higher requirements have been put forward for the performance and quantity of cables. Therefore, the materials used to make cables are gradually high-grade, specialized and specialized. As the outermost material of the cable, the cable sheath has a great influence on the comprehensive performance of the cable. It not only requires excellent physical properties, such as tensile strength, elongation at break, etc., but also requires good heat resistance and Anti-aging properties, etc. Although the...
