Abstract

The invention discloses a steel wire braided rubber hose. The rubber hose comprises an inner rubber layer, two steel wire layers which are braided outside the inner rubber layer, a middle rubber layerbetween the two steel wire layers and an outer rubber layer outside the two steel wire layers, and inner rubber of the inner rubber layer comprises, by weight, 90-120 parts of nitrile rubber, 100-120parts of carbon black, 5-10 parts of white carbon black, 15-25 parts of dioctyl adipate, 5-10 parts of zinc oxide, 1-5 parts of stearic acid, 3-5 parts of antioxidants, 1-3 parts of sulfur, 0.3-0.8 part of a vulcanizing agent, 3-8 parts of adhesives, 0.5-1.5 parts of accelerants, 0.3-0.7 part of an anti-scorching agent and 3-8 parts of organic montmorillonite. According to the steel wire braidedrubber hose, pulse stress deformation is small, the rubber hose is light in weight, the bending radius is small, pulse performance is stable, and furthermore, pulse frequency breaks through 0.3 million times, so that the service life of the rubber hose is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of rubber hoses, in particular to a steel wire braided rubber hose. Background technique [0002] With the strengthening of social development and national infrastructure, some heavy industry enterprises continue to rise, and some supporting enterprises have an increasing demand for SAER17 series rubber hoses, and the requirements are getting higher and higher, and SAER17Φ|25×2-layer steel wire braided hoses have been tested. Well-known 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 the unreasonable design of the rubber formula. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and to provide a steel wire braided rubber hose, through the improvement of its rubber formula, to prepar...
