Problems solved by technology

Although there are many kinds of cables on the market, the properties of the sheath materials of most cables are still not very ideal. During the use of the cables, there are defects in the heat resistance and aging resistance, and the impact resistance is not good enough. Good, shortens the service life of the cable, increases economic pressure, and has potential safety hazards

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a heat-resistant and aging-resistant 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 there are ...
