Special filler for cold-resistant ultraviolet-resistant high-pressure rubber tubes and preparation method thereof

Abstract

The invention relates to a special filler for cold-resistant ultraviolet-resistant high-pressure rubber tubes, which is prepared from the following raw materials in parts by weight: 5-8 parts of attapulgite, 3-5 parts of meerschaum, 1-2 parts of vanadium pentoxide, 13-15 parts of ferrocene, 2-3 parts of barium stearate, 2-3 parts of polyamide wax micropowder, 2-3 parts of phytic acid, 2-3 parts of triethanolamine, 2-3 parts of triglycol diisooctoate, 50-55 parts of fly ash, a right amount of 4-6% hydrochloric acid, a right amount of water and 15-20 parts of assistant. By adding the ferrocene, the filler has ultraviolet resistance and higher photoaging resistance; by adding the triglycol diisooctoate, the cold resistance of the rubber tube can be enhanced; by using the fly ash, the cost is lowered, and the filler has favorable reinforcing performance; and the assistant can enhance the dispersity and reinforcing performance of the filler and enhance the strength and impact toughness of the high-pressure rubber tube, so that the rubber tube can not easily bubble or deform.

Description

Technical field [0001] The invention belongs to the field of high-pressure rubber hoses, and particularly relates to a special filler for cold-resistant and ultraviolet-resistant high-pressure rubber hoses and a preparation method thereof. Background technique [0002] High-pressure rubber hoses are used in mine hydraulic supports, oilfield development, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and various industrial sectors mechanized and automated hydraulic systems. And temperature petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel, lubricating oil) and water-based liquid (such as emulsion, oil-water emulsion, water), etc. and liquid transmission pipeline. [0003] The inner rubber layer of the high-pressure rubber hose has the function of making the conveying medium bear pressure and protecting the steel wire from corrosion, ...

AI Technical Summary

Problems solved by technology

At present, the rubber of high-pressure rubber hose still has some properties that need to be improved, such as aging resistance, heat resistance, low temperature resistance, acid and alkali resistance, corrosion resistance, strength, ultraviolet resistance, flame retardancy, wear resistance, toughness, impact resistance and other properties. It is not satisfactory, and the production cost is also high; it is necessary to modify the performance of the rubber hose to improve reliability and stability, prolong the service life, reduce the frequency of maintenance and replacement, and improve the production efficiency and safety of construction machinery and coal mining machinery.
