Abstract

A high-elasticity hydraulic hose and its production process relate to the technical field of rubber products, in particular to a high-elasticity hydraulic hose and its production process. The purpose of the present invention is to provide a high-elasticity hydraulic hose suitable for various complex environments and a production process thereof. A high-elasticity hydraulic hose is characterized in that it comprises an inner rubber layer, a middle rubber layer and an outer rubber layer, the inner rubber layer is provided with a flexible metal wire skeleton, and between the inner rubber layer and the middle rubber layer is provided The air cushion layer, the inner rubber layer and the air cushion layer are both bellows-shaped; the air cushion layer is covered with flexible wires to protect the air cushion layer, a ply is arranged outside the air cushion layer, and a canvas layer is arranged outside the ply; the The air cushion layer, the cord layer and the canvas layer are bonded by compound adhesive.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a high-elastic hydraulic rubber hose and a production process thereof. Background technique [0002] At present, rubber hoses are mainly used in radiators, air conditioners, and heating pipes of various vehicles such as automobiles, locomotives, and ships, and vehicles. The structure of the steel wire braided rubber hose is composed of a liquid-resistant synthetic rubber inner rubber layer, a middle rubber layer, a steel wire braided reinforcement layer I or II or III, and a synthetic rubber outer rubber layer with excellent weather resistance. Existing hydraulic hoses have poor elasticity and cannot be used in complex environments. Many efforts have been made by technical personnel to solve this problem, but no good results have been obtained. For this reason, multi-pipe connection is generally used in complex environments. This way not only affects the appearance but...
