Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] A twist-resistant high-pressure rubber hose, as shown in the figure, includes an inner rubber layer 1 and an outer rubber layer 2, and several layers of middle rubber layers 3 are arranged between the inner rubber layer 1 and the outer rubber layer 2. The described There are at least two layers of middle glue layer 3, and a repair layer 4 is arranged between the middle glue layers, and the repair layer 4 is composed of a composite material, a repair agent and a catalyst; the composite material of the repair layer 4 is epoxy ester, the repairing agent is dicyclopentadiene sealed with microcapsules, and the catalyst is Grubbs catalyst. The outer side of the inner rubber layer 1 and the inner side of the outer rubber layer 2 are provided with steel wire reinforcement, 5, to increase its strength and strong resistance to twisting; the inner rubber layer 1 ...

Abstract

The invention relates to the technical field of high-pressure rubber hoses, and discloses a twist-resistant high-pressure rubber hose, which includes an inner rubber layer and an outer rubber layer, and several middle rubber layers are arranged between the inner rubber layer and the outer rubber layer. There are at least two middle glue layers, and a repair layer is arranged between the middle glue layers, and the repair layer is composed of composite materials, repair agents and catalysts. The invention adds a repair layer between the inner rubber layers. When the rubber hose is damaged by twisting or extrusion, the repair layer can identify the occurrence of damage within a certain limit and repair the cracks by itself; greatly prolonging the life of the rubber hose Long service life, to avoid the hazard caused by hose rupture.

Description

technical field [0001] The invention relates to the technical field of high-pressure rubber hoses, in particular to a twist-resistant high-pressure rubber hose. Background technique [0002] With the development of China's economy, customers' requirements for the quality of hydraulic hoses are constantly improving. In order to ensure the strength of the hydraulic hose, steel wire is usually used as the reinforcement layer. According to different steel wire production methods, hydraulic hoses can be divided into steel wire braided hoses and steel wire wound hoses. The steel wire winding process will make the blasting performance of the hose product far better than that of the braided hose. However, the existing steel wire winding pipe is affected by the hardness of the inner rubber and the winding structure, the pipe body is bulky and hard, and the flexibility is poor, so it is not suitable for use in narrow spaces. In particular, during the use of high-pressure hoses, cra...
