Embodiment 1
[0025] The structure of the produced two-glue one-line transparent fiber-reinforced mesh pipe is as follows: figure 2 As shown, the raw material of the outer rubber layer is composed of PVC with a high degree of polymerization of the brand DH-1800 and additives. Processing technology: 100Kg of DH-1800 high-polymerization PVC, 3Kg of organotin stabilizer, 0.7Kg of paraffin, 0.8Kg of stearic acid, 65Kg of epoxy soybean oil, 3Kg of ACR processing modifier, and 5Kg of light calcium carbonate were mixed at 65°C Mix in the high-speed mixer for 10 minutes, then cold mix to 40°C and take out the pot, and then granulate in a twin-screw extruder. The granulation temperature is 96°C, 110°C, 112°C, 115°C, 118°C. Finally, the outer rubber layer of the composite hose is extruded through a single-screw extruder, and the extrusion temperature is 116°C, 138°C, 140°C, 145°C, 148°C.
Embodiment 2
[0027] The structure of the produced three-glue two-wire fiber-reinforced PVC pipe is as follows image 3 As shown, the raw material of the outer rubber layer is composed of YH-2500 high-polymerization PVC and SG-3 PVC resin alloy plus additives. Processing technology: 100Kg of YH-2500 high degree of polymerization PVC, 5Kg of calcium zinc stabilizer, 0.5Kg of PE wax, 0.7Kg of stearic acid, 75Kg of DOP, 3Kg of ACR processing modifier, 5Kg of CPE, and 100Kg of SG-3 resin are mixed in a mixer Mix for 10 minutes, then cold mix to 40°C and take out of the pot, then granulate in a twin-screw extruder at 96°C, 110°C, 112°C, 115°C, 118°C, and finally extrude through a single screw Extrude the outer rubber layer of the composite hose by machine, and the extrusion temperature is 116°C, 138°C, 140°C, 145°C, 148°C.
