Ocean cable sheath material with high strength and strong corrosion resisting performance

Abstract

The invention discloses an ocean cable sheath material with high strength and strong corrosion resisting performance. The ocean cable sheath material is prepared from the following raw materials in parts by weight: 53 to 68 parts of acrylonitrile-butadiene rubber, 19 to 24 parts of polyvinyl alcohol resin, 15 to 21 parts of polytetrafluoroethylene, 3 to 9 parts of ammonium bicarbonate, 2 to 6 parts of barium stearate, 1 to 4 parts of vinyl trimethoxy silane, 2 to 7 parts of polytetramethylene ether glycol, 1 to 5 parts of sodium dialkyl sulfate, 1 to 4 parts of manganese acetate, 2 to 5 partsof sodium chromate, 1 to 4 parts of hexamethylenetetramine, 1 to 5 parts of phenylmethyl silicone oil, 3 to 10 parts of zinc oxide, 1 to 4 parts of ammonia water, 2 to 7 parts of borax, 1 to 5 parts of white carbon black, 1 to 6 parts of glass fibers, 1 to 2 parts of talcum powder, 2 to 5 parts of liquid paraffin wax, 2 to 6 parts of titanium white powder, 1 to 4 parts of an antioxidant BHT, 2 to5 parts of a maleic anhydride grafted compatibilizer, 1 to 4 parts of a vulcanizing agent and 1 to 4 parts of an anti-ageing agent. By adopting the ocean cable sheath material, the rigidity and the corrosion resisting performance of a cable sheath are improved. The cable sheath material is reasonable in component ratio and has good chemical stability and corrosion resisting performance; parametersare not greatly changed under acid, alkali and salt and damp and hot conditions, and the performance parameters are stable.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a marine cable sheath material with high strength and strong corrosion resistance. Background technique [0002] The ocean can provide human beings with material resources, space resources and energy for survival and development. my country is a big maritime country with a coastline of more than 18,000 kilometers, more than 6,500 coastal islands, and over 3 million square kilometers of sea area under its jurisdiction. my country has abundant marine resources and a booming marine industry, but the marine environment is very harsh and highly corrosive. Seawater itself is a strong corrosive medium. At the same time, waves, waves, tides, and currents generate low-frequency reciprocating stress and Shock, coupled with marine microorganisms, attached organisms and their metabolites, all directly or indirectly accelerate the corrosion process. Marine corrosion is mainly localiz...
