Problems solved by technology

[0002] 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.
