Special packing material for high-toughness water-resistant high-pressure rubber tube and preparation method thereof

Abstract

The invention discloses a special packing material for a high-toughness water-resistant high-pressure rubber tube. The special packing material is prepared from the following raw materials in parts by weight: 2-3 parts of epoxy acrylate, 5-10 parts of ABS (Acrylonitrile Butadiene Styrene) resin, 3-4 parts of tridecafluoro trimethoxy silane, 0.3-0.4 part of tetraethoxysilane, 10-15 parts of chalk powder, 0.4-0.5 part of chlorinated paraffin, 0.4-0.5 part of epoxy ethylhexyl stearate, 50-55 parts of coal ash, a proper amount of 4-6% hydrochloric acid, a proper amount of water and 15-20 parts of additives. Due to the added tridecafluoro trimethoxy silane, the high-pressure rubber tube is good in hydrophobic, antifouling and uvioresistant property, and the service life is prolonged; due to the epoxy acrylate, the ABS resin and the tetraethoxysilane, the toughness and tearing strength of the high-pressure rubber tube are improved; due to the coal ash and the chalk powder, the cost is lowered, and the reinforcement property is good; due to the additives, the dispersity and reinforcement property of the packing material are improved, and the strength and impact resisting toughness of the high-pressure rubber tube are improved.

Description

technical field [0001] The invention belongs to the field of high-pressure rubber hoses, in particular to a special filler for high-toughness water-resistant and high-pressure rubber hoses and a preparation method thereof. Background technique [0002] High-pressure 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. Petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water) and pipelines for liquid transmission. [0003] The inner rubber layer of the high-pressure hose has the function of making the conveying medium withstand pressure and protecting the steel wire from erosion, and the outer rubber layer protects the steel wire from damage. At present, th...

AI Technical Summary

Problems solved by technology

At present, the rubber of high-pressure 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. As expected, the production cost is also high; the performance of the rubber hose needs to be modified 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.
