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.

Abstract

The invention discloses a method for producing a polyvinyl chloride (PVC) compound hose. The method comprises production of an inner glue layer and production of an outer glue layer, wherein during production of the inner glue layer, common PVC is taken as a raw material, and during production of the outer glue layer, high-polymerization-degree PVC or an alloy of the high-polymerization-degree PVC and the common PVC is taken as a raw material. The inner glue layer and the outer glue layer are produced by adopting materials in different formulas; and the high-polymerization-degree PVC or the alloy of the high-polymerization-degree PVC and the common PVC replace for the common PVC, so the abrasion resistance of the PVC compound hose is improved greatly and the service life is prolonged on the premise of slight increase of the cost.

Description

technical field [0001] The invention relates to the field of PVC pipes, in particular to a production method of PVC composite hoses. Background technique [0002] There are many types of PVC hoses on the market, and most PVC hoses will be in contact with the outside world during use, causing friction. Therefore, the outer layer of the hose needs to have high wear resistance. The inner layer of the hose is generally used to guide the flow of liquid, and the requirements for wear resistance are not high. [0003] In the existing PVC composite hose, the inner and outer layers are generally produced with the same formula material. The inner and outer layers of the hose made of PVC material with ordinary polymerization degree are not strong in wear resistance, resulting in short service life; the inner and outer layers of the hose made of high polymerization degree PVC material have enhanced wear resistance and longer service life , but the cost is high and often cannot be acce...
