Description

technical field [0001] The invention relates to a cable sheath material, in particular to an underground cable sheath material and a preparation method thereof. Background technique [0002] The cable sheath is the protective layer of the outer layer of the cable. It is used to protect the cable and ensure the safe operation of the cable. Therefore, the cable sheath material is required to have certain wear resistance, aging resistance, and excellent mechanical properties. Underground cables are different from overhead cables. They are often installed in cable trenches, tunnels or sea water, and are often exposed to water and soil layers. Therefore, higher requirements are put forward for the underground cable sheath material. [0003] Chinese Patent Publication No. CN108250733A discloses a waterproof submarine cable protective sheath and its preparation method. The preparation method comprises: 1) adding vinyl chloride, boron nitride, sodium bicarbonate, starch, molecular ...
