Problems solved by technology

[0002] The rubber hose in the existing power steering system, the rubber layer is generally made of chlorosulfonated polyethylene rubber as the main raw material, supplemented by carbon black, accelerator and other materials as auxiliary agents, mixing and extruding, but in the mixing process The ratio of main raw materials, accelerators, carbon black types and other auxiliary agents affect the high pressure resistance of the adhesive layer. The existing products are affected by the above factors and processing technology, and their high pressure resistance often reaches Less than demand, short service life, unable to meet the needs of the growing automotive industry
