Abstract

The invention provides a low temperature resistant and corrosion resistant marine cable sheath and a preparation method thereof. The cable sheath is prepared from, by weight, 25-35 parts of fluorinated silicone rubber, 20-30 parts of low temperature resistant silicone rubber, 15-20 parts of fluorine rubber, 15-25 parts of modified kaolin, 10-15 parts of plasticizer TOTM, 5-8 parts of polyvinyl chloride, 1-4 parts of stabilizer, 5-10 parts of light magnesium oxide, 3-5 parts of epoxidized rapeseed oil, 2-4 parts of antioxidant, 10-20 parts of carbon black and 2-4 parts of graphene nanoplatelets. The low temperature resistant and corrosion resistant marine cable sheath has very good cold resistance and corrosion resistance, corrosion of sea water can be resisted, and the cable sheath can be used for a long time at the low temperature of -100 DEG C; meanwhile, excellent physical and mechanical properties are achieved, the wear resistant property and insulating property are good, the aging speed can be obviously reduced, and the use time is longer.

Description

technical field [0001] The invention belongs to the technical field of cable sheaths, and in particular relates to a low-temperature-resistant and corrosion-resistant marine cable sheath and a preparation method thereof. Background technique [0002] With the rapid development of power cables, higher requirements are put forward for cable protection. Cable sheathing is the most commonly used electrical insulation material for protecting wires and cables. It is widely used because of its good insulation performance, high chemical stability, no rust, no aging, and adaptability to harsh environments. In the production process of marine cables, the corrosion resistance of the cables is very high. At present, many inferior raw and auxiliary materials are used in the cable sheaths and sheath materials in the market. As time goes on, it will cause great damage to the conductive copper wires in the cables. Large damage, which seriously affects the performance of the cable. How to ...
