Description

Technical field [0001] The invention relates to the technical field of cables, in particular to an anti-aging and high temperature resistant cable sheath material and a preparation method thereof. Background technique [0002] The cable jacket is a layer of rubber or rubber composite sheath that protects the cable from damage caused by the natural environment and external factors, and can insulate to ensure that foreign objects are not harmed. The cable jacket is a rubber layer wrapped around the cable core , Play the role of insulation and protection of the internal conductor, the quality of the cable sheath depends on the insulation performance, fire resistance and mechanical properties of the sheath. [0003] Most cables are directly placed outdoors and exposed to wind and rain. The cable sheath is prone to aging. Especially in hot summer days, when the cable is exposed to sunlight, the surface temperature rises rapidly, and it is exposed to a high temperature environment for a ...
