Problems solved by technology

[0003] Some communication cables are located indoors and are less affected by the environment, but many communication cables are placed directly outdoors, exposed to wind and sun, and the communication cable sheath is easy to age. Some aged cable sheaths will be carbonized, causing the cable The material becomes brittle, the strength is greatly reduced, and it is easy to break, which is not conducive to the effective protection of the cable. Moreover, the insulation of the aging cable material becomes poor, and it is prone to leakage, which affects the safety of the communication cable.

Description

Technical field [0001] The invention relates to the technical field of electronic communication, in particular to an anti-aging communication cable material and a preparation method thereof. Background technique [0002] Communication cables are cables that transmit telephones, telegraphs, fax documents, TV and radio programs, data and other electrical signals, and are formed by twisting more than a pair of insulated wires. The outer layer of the communication cable is a cable sheath. The cable sheath is a layer of insulating material that protects the cable from damage caused by external factors, and can ensure that the cable is not damaged by foreign objects. [0003] Some communication cables are located indoors and are less affected by the environment. However, many communication cables are directly placed outdoors and are exposed to wind and sun. The communication cable sheath is prone to ageing. Some aging cable sheaths will be carbonized, causing the cable The material beco...
