Abstract

The invention relates to the technical field of cable protection equipment, in particular to a marine high-performance rubber and plastic sheath material and a preparation process thereof. The marine high-performance rubber and plastic sheath material comprises the following raw materials in percentage by weight: 12-17% of hydrogenated nitrile rubber, 3-6% of rare earth, 45-50% of attapulgite, 0.5-1.5% of a lubricant, 1-1.5% of an antioxidant, 6.5-7.5% of a flexibilizer, 11-13% of a flame retardant, 2-3% of a coupling agent, 2-3% of a compatilizer, 1-2% of a light stabilizer and 1.5-2.5% of color master batch. The material is made of hydrogenated nitrile rubber, has excellent oil resistance, corrosion resistance, low temperature resistance, high temperature resistance, oxidation resistance, dynamic fatigue resistance and ozone resistance, can resist high temperature of 150-170 DEG C, has cold resistance superior to that of fluororubber, has acid resistance and oil resistance 5 times that of common NBR, and adapts to marine environments such as high salt, heavy storm waves, strong ultraviolet rays, high water pressure, marine organisms, dynamic loads and the like.

Description

technical field [0001] The invention relates to the technical field of cable protective equipment, in particular to a marine high-performance rubber and plastic sheath material and a preparation process. Background technique [0002] The marine umbilical cable is a high-tech integrated cable that integrates functions such as power transmission digital models, video signal transmission, and gas or liquid transportation. Under the complex ocean bottom conditions, the marine umbilical cable is used in a high-voltage, high-acid and alkali self-shielding environment during use. The cable is used for deep-sea trenching, seabed salvage, seabed mining, ocean exploration, seabed robots and large-scale seabed tourism. Projects and other marine engineering. [0003] In recent years, the development of marine photovoltaics, wind power generation, underwater robots, oil exploration and military has put forward higher requirements for marine umbilical cables. Therefore, the sheath mater...
