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...
