Description

technical field [0001] The invention relates to an outer rubber tube for hydraulic oil pipes, in particular to an outer rubber tube for hydraulic oil pipes with excellent comprehensive mechanical properties and outstanding corrosion resistance, belonging to the technical field of hydraulic fittings. Background technique [0002] Hydraulic oil pipes are widely used in large construction machinery and equipment such as excavators, loaders, and road rollers. Due to the complex and changeable working environment of construction machinery and equipment, the equipment is easily affected by external factors such as temperature, humidity, and oil pollution, especially hydraulic oil pipes. Affected by oil pollution over time, it is easy to accelerate the aging of the outer rubber hose, affecting the overall service life of the hydraulic oil pipe, and in severe cases, the entire construction machinery and equipment can not be used normally.

Problems solved by technology

[0002] Hydraulic oil pipes are widely used in large-scale construction machinery equipment such as excavators, loaders, and road rollers. Due to the complex and changeable working environment of construction machinery equipment, the equipment is easily affected by external factors such as temperature, humidity, and oil pollution, especially hydraulic oil pipes. Oil corrosion over time will easily accelerate the aging of the outer rubber hose, affect the overall service life of the hydraulic oil pipe, and even lead to the failure of the entire construction machinery and equipment in severe cases

[0003] Most of the current measures to improve the corrosion resistance of the outer hose used for hydraulic oil pipes are to improve its material. The use of fluorine rubber, modified nitrile rubber, fluorosilicone rubber and other materials can effectively improve the corrosion resistance of the outer hose, but the above materials cannot be used in Strength, heat resistance and aging resistance are effectively balanced, so that the service life and performance of hydraulic oil pipes are limited. Therefore, the outer rubber hose for hydraulic oil pipes needs further research and development in terms of corrosion resistance
