Abstract

The invention discloses a compact steel wire braided rubber hose, which comprises an inner rubber layer, two steel wire layers which are braided outside the inner rubber layer, a middle rubber layer between the two steel wire layers and an outer rubber layer outside the steel wire layers. The inner rubber of the inner rubber layer, the middle rubber of the middle rubber layer and the outer rubber of the outer rubber layer are made of the following raw materials: raw rubber, reinforcing agents, softening agents, minor ingredients, adhesive and accelerating agents. The invention additionally discloses a preparation method of the compact steel wire braided rubber hose. The compact steel wire braided rubber hose has the advantages that the structure is reasonable, the pulse compression deformation is small, the weight of the rubber hose is light, the bending radius is small, all performances of the finished product satisfy requirements in notes of SAEJ517R17, the pulse performance is stable, the pulse times exceeds 300 thousand and the service life of the rubber hose is greatly prolonged.

Description

technical field [0001] The invention relates to a steel wire braided rubber hose, and also relates to a preparation method of the rubber hose. Background technique [0002] At present, many heavy industry supporting enterprises have a great demand for SAE R17 series hoses, and the requirements are getting higher and higher, while SAER17 The 25×2-layer steel wire braided rubber hose has been tested. Well-known domestic rubber hose manufacturers only reach about 100,000 times, and rarely reach the 200,000 times required by the standard, which is far from meeting the needs of customers. The main reason for this problem is that the formula of the rubber compound and the design of the skeleton layer are unreasonable. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a dense steel wire braided rubber hose and its preparation method. The dense steel wire braided rubber hose is an SAE R17 rubber hose with c...
