Problems solved by technology

However, the current high-pressure flexible rubber hose is prone to the problem of detachment between layers, and it is easy to make the solute stay in the scar, which will affect the life of the hose under long-term corrosion.
And the existing high-pressure flexible rubber hose has the problem of poor pressure resistance

Embodiment 1

[0019] The high-pressure flexible rubber hose is characterized in that it includes an inner rubber layer, a high-elasticity rubber layer is arranged outside the inner rubber layer, a non-woven wrapping layer is arranged outside the high-elasticity rubber layer, and a medium rubber layer is arranged outside the non-woven wrapping layer. , steel mesh is staggered in the middle rubber layer; polyethylene film is arranged outside the middle rubber layer, and protective armor is arranged outside the polyethylene film.

[0020] An outer sheath is provided between the polyethylene film and the protective armor.

[0021] The manufacturing process of the high pressure flexible rubber hose is as follows.

[0022] In the first step, the inner rubber layer and the inner rubber cloth layer are sequentially formed on the surface of the core rod on the molding machine to form a semi-finished product; the inner surface of the inner rubber layer is provided with an intermediate layer, the inte...

Abstract

A high-pressure flexible rubber hose and a manufacturing process thereof relate to the technical field of rubber products, in particular to a high-pressure flexible rubber hose and a manufacturing process thereof. The object of the present invention is to provide a high-pressure flexible rubber hose with tight connection between layers and strong pressure resistance. A high-pressure flexible rubber hose is characterized in that: it includes an inner rubber layer, and a high elastic rubber layer is arranged outside the inner rubber layer, and a non-woven fabric winding layer is arranged outside the high elastic rubber layer; In the rubber layer, the steel wire mesh is staggered in the middle rubber layer; the polyethylene film is arranged outside the middle rubber layer, and the protective armor is arranged on the outside of the polyethylene film.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a high-pressure flexible rubber hose and a manufacturing process thereof. Background technique [0002] At present, rubber hoses are widely used. In order to cope with changes in different environments, high-pressure flexible rubber hoses have gradually entered people's field of vision. High-pressure flexible rubber hoses have the characteristics of good flexibility and strong tensile strength, and perform in complex environments. very good. However, the current high-pressure flexible rubber hose is prone to the problem of interlayer detachment, which is easy to cause the solute to stay in the scar and corrode for a long time, which affects the life of the hose. In addition, the existing high-pressure flexible rubber hose has the problem of poor pressure resistance. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a high-pressure fl...
