Problems solved by technology

[0002] With the rapid development of wireless communication tools, radio and television industry, the comprehensive promotion of office computer automation, and the rapid popularization of electric vehicles, electromagnetic radiation can be described as ubiquitous and pervasive, becoming a new type of environmental pollution; at the same time, with the development of technology , cables are also widely used in power systems, information transmission, instrument systems and other fields, while PVC materials are light in weight, good in mechanical strength, and have excellent flame retardancy and corrosion resistance, low price and cost, and wide sources. Widely used in cable protection materials, but the heat resistance, current carrying capacity and thermal stability are low, and the electrical insulation performance is still insufficient. At the same time, due to the harsh application environment of cable protection tubes, it is necessary to modify the properties of cable materials to improve The service life of the protection tube can avoid leakage or short circuit accidents caused by internal wire leakage or wire disconnection due to damage to the cable protection tube
