Abstract

The invention discloses special packing for a wear-resistant and corrosion-resistant high-pressure rubber pipe. The special packing is prepared from the following raw materials in parts by weight: 3-5 parts of ferroferric oxide, 1-2 parts of tantalum boride, 7-9 parts of spodumene, 1-2 parts of tantalum diboride, 2-3 parts of p-tert-butylbenzoic acid, 8-10 parts of magnesium aluminate spinel, 3-4 parts of niobium boride, 3-5 parts of butylated hydroxytoluene, 2-5 parts of composite lead stabilizer, 1.3-1.8 parts of zinc stearate, 1-2 parts of calcium stearate, 50-55 parts of coal ash, a proper quantity of 4-6% hydrochloric acid, a proper quantity of water and 15-20 parts of auxiliary. Due to the addition of ferroferric oxide and the magnesium aluminate spinel in the packing, the wear resistance and heat resistance of the rubber pipe are improved; due to the addition of p-tert-butylbenzoic acid, the rubber pipe has favorable chemical corrosion resistance and soapy water resistance and is suitable for conveying chemicals; due to the adoption of the coal ash, the cost is reduced, and the reinforcing property of the packing is good; due to the adoption of the auxiliary, the dispersibility and reinforcing property of the packing can be improved, the strength and impact toughness of the high-pressure rubber pipe can be improved, and the high-pressure rubber pipe is not easy to bubble and deform.

Description

technical field [0001] The invention belongs to the field of high-pressure rubber hoses, in particular to a special filler for wear-resistant and corrosion-resistant high-pressure rubber hoses 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 eros...
