Abstract
The present invention relates to an ultra-high molecular weight polyethylene enhanced high-flow delivery high-pressure hose and manufacturing method thereof. The hose includes an outer rubber layer, a reinforcing layer and an inner rubber layer from outside to inside. A thickness of the outer rubber layer is 0.3-6.0 mm. A thickness of the reinforcing layer is 1.0-5.0 mm. A thickness of the inner layer is 0.3-5.0 mm. The outer rubber layer and the inner layer are obtained by co-extruding onto the reinforcing layer using a coextrusion equipment. The manufacturing method includes the following steps: rubber mixing, preparing the reinforcing layer, producing a finished product, vulcanizing and pressure testing. The hose of the invention has the advantages of light weight, good flexibility, abrasion resistance, corrosion resistance and good weather fastness. The hose can be connected through a plurality of standard buckles, which is easy to wind up, easy to assemble and disassemble.
