Problems solved by technology

[0003] For rubber hoses, their strength and wear resistance are generally not large, and they will be damaged too quickly when used in occasions with a large friction coefficient. The outer layer of the hose is prone to large-scale wear, making the use of rubber hose shortened time

Embodiment 1

[0041] see Figure 1-4 , a highly wear-resistant rubber hose, including an inner rubber layer 1 and an outer rubber layer 2 that are connected with the inner and outer layers. The outer end wall of the outer rubber layer 2 is annularly distributed with a plurality of convex wear-resistant protruding outwards. Adhesive layer 3, the lower end walls of a plurality of convex anti-abrasion adhesive layers 3 are embedded and connected with the outer end walls of the inner adhesive layer 1. The inner adhesive layer 1, the outer adhesive layer 2 and the convex abrasion-resistant adhesive layer 3 are all composed of The raw material components in parts are composed of 50-65 parts of natural rubber, 45-65 parts of nitrile rubber, 35-50 parts of cis-butadiene rubber, 60-80 parts of butadiene nitrile, and 5-10 parts of anti-aging agent.

[0042] see Figure 4-6 , the plurality of convex anti-abrasion rubber layers 3 and the outer rubber layer 2 are integrally formed, and one-shot injecti...

Abstract

The invention discloses a high wear-resistant rubber hose, which belongs to the field of rubber hoses. A high wear-resistant rubber hose is provided with a plurality of convex anti-wear protruding outwards on the outer end wall of the outer rubber layer. Rubber layer, a plurality of convex anti-friction rubber layers protruding outward are used as anti-friction bumps, and the outer end of the anti-friction bumps is covered with an outer anti-friction layer, which effectively reduces the wear surface of the outer end surface of the hose. At the same time, An injection cavity corresponding to the position of the convex anti-wear rubber layer is set on the outer end wall of the inner rubber layer, and a flexible reinforcement is embedded inside the convex anti-wear rubber layer, and one end of the flexible reinforcement extends into the injection cavity. Then, by adding a foamed resin layer inside and outside the injection cavity and the flexible reinforcement, on the one hand, it is beneficial to improve the mechanical strength of the hose, and it is not easy to cause the inner and outer layers of the hose to age and peel off each other due to excessive use. The flexibility and pressure resistance of the hose are further improved, thereby indirectly enhancing the wear resistance of the hose.

Description

technical field [0001] The invention relates to the field of rubber hoses, and more particularly, to a high wear-resistant rubber hose. Background technique [0002] The rubber hose is a steel wire braided hose. The hose is composed of an inner rubber layer, a steel wire braided layer and an outer rubber layer. It is suitable for transporting hydraulic fluids, such as alcohol, fuel oil, lubricating oil, emulsion, etc. The existing rubber hose usually includes an inner tube and an outer tube. The inner tube is processed first, and then the outer tube is covered on the outside of the inner tube. Fabric or wire is added to the inner tube to increase the strength of the hose. [0003] For rubber hoses, their strength and wear resistance are generally not large. When used in occasions with a large friction coefficient, the damage is too fast. The outer layer of the hose is prone to large area wear, which makes the use of rubber hoses time is shortened. [0004] To this end, w...
