Abstract

The invention discloses a special packing for a high-pressure rubber tube for petroleum transportation. The packing is prepared from the following raw materials in parts by weight: 15-20 parts of chlorosulfonated polyethylene, 10-15 parts of semi-reinforcing carbon black, 1-2 parts of cerium tetrafluoride, 1-2 parts of cobalt naphthenate, 3-6 parts of nanoscale titanium dioxide, 1-2 parts of cuprous chloride, 3-5 parts of graphene, 1-2 parts of capric acid, 1-2 parts of sulfonated lanolin, 60-65 parts of pulverized fuel ash, a proper amount of 4-6% hydrochloric acid, a proper amount of water, and 15-20 parts of auxiliaries. The chlorosulfonated polyethylene, semi-reinforcing carbon black, nanoscale titanium dioxide and graphene are added in the packing, so that the rubber tube has excellent antiskid, anti-wear, oil-resistant and corrosion-resistant properties, as well as an corrosion resistance property; through the use of pulverized fuel ash, the cost is lowered, and the reinforcing property is good; through the use of the auxiliaries, the strength and impact toughness resistance of the high-pressure rubber tube can be enhanced, and the high-pressure rubber tube is not easily blistered and deformed. The packing is applicable to production of high-pressure rubber tubes for oil transportation, long in service life, and safe and reliable.

Description

technical field [0001] The invention belongs to the field of high-pressure rubber hoses, and in particular relates to a special filler for high-pressure rubber hoses used for oil transportation and a preparation method thereof. Background technique [0002] High-pressure rubber hoses are used in mine hydraulic supports, oil field development, engineering construction, lifting transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and various industrial sectors. Mechanized and automated hydraulic systems have a certain pressure Petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquid (such as emulsion, oil-water emulsion, water) and pipelines for liquid transmission. [0003] The inner rubber layer of the high-pressure rubber hose has the function of making the conveying medium withstand pressure and protecting the steel wire from ero...
