Problems solved by technology

During the service life of the cable, the sheath must protect the cable core from moisture and other pollution. The degree of protection should keep the circuit performance in the cable core normal. Once too much moisture or other pollutants enter the cable core, the transmission performance will be affected. will seriously deteriorate
This requires the cable sheath to have high mechanical strength and internal toughness to prevent cracking or damage in harsh environments, resulting in abnormal cable transmission or potential safety hazards
[0003] Cables used in outdoor, underwater or other environments are often in contact with corrosive substances, especially in poor outdoor environments, often encountering rainwater with a certain pH value, coupled with sunlight, high temperature, etc. Environmental conditions, long-term use of the cable sheath often appear aging cracks and other phenomena, resulting in varying degrees of circuit failures, affecting people's normal life and work

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a sun-resistant and anti-corrosion cable sheathing material and a preparation method thereof. Background technique [0002] Wire and cable are the carriers of power transmission and information transmission, and are widely used in industrial and civil electrical facilities. Wires and cables are used in different environments or occasions and have different requirements, which puts forward higher requirements for the cable sheath covering the outside of the cable. The main function of the cable sheath is to mechanically and electrically protect the transmission cable from various conditions that will cause it to lose its transmission function. The cable jacket must fulfill this protective function during installation, splicing and throughout the service life of the cable. During the service life of the cable, the sheath must protect the cable core from moisture...
