Seawater-corrosion-resistant cable material for submarine cable

The invention discloses a seawater-corrosion-resistant cable material for a submarine cable. The seawater-corrosion-resistant cable material comprises the following raw materials by weight: 36 to 40 parts of butadiene-acrylonitrile rubber, 12 to 14 parts of low-density polyethylene, 16 to 18 parts of SEBS resin, 7 to 9 parts of maleic anhydride grafted ethylene-vinyl acetate copolymer, 2.6 to 3.2 parts of an antioxidant, 3.5 to 5.5 parts of a cross-linking agent, 1.6 to 2.4 parts of silicone oil, 1.4 to 1.8 parts of an anti-oxidant BHT, 5.5 to 6.5 parts of carbamate and 2.2 to 3.4 parts of hydroxyethyl cellulose. The seawater-corrosion-resistant cable material has more excellent break resistance and mechanical strength and good resistance to corrosion, acid and alkali, and exerts good protection effect on the cable. 本发明公开了种耐海水腐蚀海底电缆用电缆料，各原料以重量份计如下：丁晴橡胶36～40份，低密度聚乙烯12-14份，SEBS树脂16～18份，马来酸酐接枝乙烯-醋酸乙烯酯共聚物7～9份，防老剂2.6～3.2份，交联剂3.5-5.5份，硅油1.6～2.4份，抗氧剂BHT 1.4～1.8份，氨基甲酸酯5.5～6.5份，羟乙基纤维素2.2-3.4份；本发明具有更优良的抗断裂性能和机械强度，同时具有良
