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.

Claim (Index 2):
A manufacturing method of an ultra-high molecular weight polyethylene enhanced high-flow delivery high pressure hose of  claim 1 , comprising the following steps:\n (1) rubber mixing: a technical formulation of the rubber are as follows by mass fraction: 90-110 parts of rubber, 5-10 parts of zinc oxide, 1-2 parts of stearic acid, 1-2 parts of microcrystalline wax, 2-5 parts of pvc stabilizer, 1-2 parts of antioxidant, 12-20 parts of white carbon black, 5-10 parts of titanium dioxide, 1.5-3 parts of resorcinol, 1.5-3 parts of accelerant hexamethylenetetramine, 1.5-5 parts of resin, 1.5-3 parts of accelerant CZ, 0.4-0.8 parts of accelerant TMTM, 1.8-2.5 parts of sulfur, 15-30 parts of dioctyl phthalate, and the pigment is replenished as needed; putting the above materials, except the sulfur, accelerant TMTM and accelerant CZ, into an internal mixer, wherein the mixing time is greater than or equal to 7 minutes, the discharging temperature is between 100-120\u00b0 C., and mixing on the open mill for 2-3 times, then entering into the rubber filter for straining, adding accelerants TMTM and CZ into the filtered rubber compound in proportion, sheeting out to obtain a rubber material, cooling and standby for application; (2) preparing the reinforcing layer: mixing the ultrahigh molecular weight polyethylene and the polyester filament in a certain ratio, wherein a mixing ratio thereof is 0-100%, wherein the ultrahigh molecular weight polyethylene and the polyester filament are made into warps and wefts respectively, braiding into a tubular reinforcing layer using a circular loom; (3) producing a finished product: putting the reinforcing layer on a core of the coextrusion mold, putting the rubber material in step (1) into an extruder, wherein a temperature of the extruder is set at 45-85\u00b0 C., starting the extruder, wherein a squeezing speed of the extruder is 10-50 rpm, and then starting the dragger so that the reinforcing layer squeezing out of the coextrusion mold with a base. The rubber material penetrates the reinforcing layer and forms the inner layer along with the base when passing through the coextrusion mold, at the same time, attaching to the surface of the reinforcement layer to become the outer layer. The dragger drags the outer layer to a cooling device in a speed of 2-5 m/min, and then reaches the vulcanization line to be vulcanized; (4) vulcanizing: applying clamps on two ends of the semi-product of step (3) on the ultralong vulcanization line, steaming on one end, wherein a vapor pressure of the vulcanization is 0.1-0.3 MPa with a time of 10-600 minutes to obtain the finished product; (5) pressure testing: dragging the product to a dedicated pressure test machine, applying clamps on the two ends, injecting water, testing the product under a pressure of 1.5-2 times of the design pressure to check whether leakage or not.
