High-wear-resistance pure rubber hose

Abstract

The invention discloses a high-wear-resistance pure rubber hose, and belongs to the field of rubber hoses, according to the high-wear-resistance pure rubber hose, a plurality of convex anti-wear rubber layers protruding outwards are arranged on the outer end wall of an outer rubber layer and serve as anti-wear convex points, and the outer end faces of the anti-wear convex points are coated with an outer anti-wear layer; meanwhile, the outer end wall of the inner rubber layer is provided with a material injection cavity corresponding to the position of the convex anti-abrasion rubber layer, a flexible reinforcing piece is embedded in the convex anti-abrasion rubber layer, one end of the flexible reinforcing piece extends into the material injection cavity, and foaming resin layers are additionally arranged inside and outside the material injection cavity and the flexible reinforcing piece, so that the anti-abrasion performance of the hose is improved. On one hand, the mechanical strength of the hose is improved, the inner layer and the outer layer of the hose are not prone to aging and mutual stripping caused by long-time use, on the other hand, the flexibility and the pressure resistance of the hose are further improved, and therefore the abrasion resistance of the hose is indirectly enhanced.

Description

technical field [0001] The invention relates to the field of rubber hoses, in particular to a highly wear-resistant pure rubber hose. 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. It is suitable for conveying 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 outside the inner tube, and the rubber Fabric or wire is added to the inner tube to add strength to the hose. [0003] For rubber hoses, their strength and wear resistance are generally not high, and they will be damaged too quickly when used in occasions with a large friction coefficient. Time shortened. [0004] For this reason, we propose a kind of highly wear-resistant pure rubber hose to effectively solve some pr...

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
