Abstract

The invention discloses a rubber hose with good high-pressure-resistant bending performance. The rubber hose is composed of inner-layer rubber, outer-layer rubber and high-strength fibers; the high-strength fibers are arranged between the inner-layer rubber and the outer-layer rubber; the inner layer rubber and the outer layer rubber are prepared from the following raw materials in parts by mass;40-60 parts of chloroprene rubber, 30-50 parts of butyl rubber, 2-5 parts of petroleum ether, 2-4 parts of borax, 4-8 parts of mica powder, 4-6 parts of carbon black, 1-6 parts of stearic acid, 2-6 parts of a plasticizer, 3-8 parts of an accelerant M, 1-2 parts of sulfur, 1-3 parts of a vulcanizing agent and 1-2 parts of a vulcanization accelerator. According to the invention, the chloroprene rubber and the butyl rubber are used as main materials; petroleum ether, borax, mica powder, carbon black, stearic acid, the plasticizer and the accelerant M in a specific proportion are matched, so thatthe high-pressure resistance is greatly improved, the softness and the viscosity are also greatly improved, the bendable angle of the rubber hose with the same caliber is larger than that of a traditional rubber hose, and thus the applicability is improved.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to a rubber hose with good high-pressure resistance and bending performance. Background technique [0002] The rubber hose is a steel wire braided hose. The rubber hose consists of an inner rubber layer, a steel wire braid layer and an outer rubber layer. Suitable for conveying hydraulic fluids, such as alcohol, fuel oil, lubricating oil, emulsion and so on. [0003] Traditional rubber hoses have poor high-pressure resistance. When used in a long-term high-pressure environment, tube bursts are prone to occur, and traditional rubber hoses also have poor bending performance. Therefore, an improved technology is urgently needed to solve the problem. This problem that exists in the prior art. Contents of the invention [0004] The object of the present invention is to provide a rubber hose with good high-pressure bending resistance, so as to solve the problems raised in the ab...
