Description

technical field

[0001] The invention belongs to the technical field of rubber products, and in particular relates to a rubber composition, a rubber product, a hydraulic hose and a preparation method thereof. Background technique

[0002] Hydraulic rubber hose is also known as hydraulic oil pipe, hydraulic hose, high-pressure hose, and hydraulic pipe. The hydraulic hose structure is mainly composed of a liquid-resistant synthetic rubber inner rubber layer, a middle rubber layer, a multi-layer reinforcement layer, and a weather-resistant synthetic rubber outer rubber layer. The inner rubber layer has the function of making the conveying medium bear the pressure and protecting the steel wire or wire fiber from erosion. The outer rubber layer protects the reinforcing layer from damage. .

[0003] Hydraulic hoses are divided into steel wire braided hoses, steel wire wound hoses, wire braided hoses and cloth-covered hoses according to the production process. Steel wire hydrauli...
