▎ 摘  要

NOVELTY - Manufacture of tensile plastic pipe involves adding high-density polypropylene, acetal resin, and bisphenol A-type epoxy resin to a mixer, heating, stirring to obtain a mixture (a1), crushing sepiolite, sieving to obtain sepiolite powder, mixing the sepiolite powder with graphene oxide in a ball mill, adding deionized water, grinding, vacuum-filtering, vacuum-drying, pulverizing, sieving to obtain a dried mixture (m2), mixing 15-25 pts. wt. polyoxypropylene glyceryl ether, 8-10 pts. wt. polydimethylsiloxane, and 6-8 pts. wt. diacetone acrylamide in an ultrasonic oscillator, ultrasonically treating to obtain a mixture (m3), mixing 5-9 pts. wt. carbon nanotubes and 4-6 pts. wt. lignocellulose in a vacuum reactor, heating, stirring, cooling, adding 2-4 pts. wt. plasticizer and 2-4 pts. wt. antioxidant, stirring to obtain a mixture (m4), mixing the mixtures (m1)-(m4) in a mixing furnace at 130-150 degrees C, stirring, melt-blending the mixture, extruding, drying, and injection molding. USE - Manufacture of tensile plastic pipe used in farmland water irrigation. ADVANTAGE - The method enables manufacture of tensile plastic pipe with high tensile strength. DETAILED DESCRIPTION - Manufacture of tensile plastic pipe involves adding 80-90 pts. wt. high-density polypropylene, 60-70 pts. wt. acetal resin, and 35-45 pts. wt. bisphenol A-type epoxy resin to a mixer, heating to 75-85 degrees C, stirring at rate of 100-120 rpm for 30-40 minutes to obtain a mixture (a1), crushing 6-10 pts. wt. sepiolite, passing through a sieve of 180-200 mesh to obtain sepiolite powder, mixing the sepiolite powder with 3-5 pts. wt. graphene oxide in a ball mill, adding 10 pts. wt. deionized water, grinding, vacuum-filtering, vacuum-drying at 80 degrees C, pulverizing, sieving with 250 mesh to obtain a dried mixture (m2), mixing 15-25 pts. wt. polyoxypropylene glyceryl ether, 8-10 pts. wt. polydimethylsiloxane, and 6-8 pts. wt. diacetone acrylamide in an ultrasonic oscillator, ultrasonically treating at 200-250 W and 70-80 degrees C for 15-25 minutes to obtain a mixture (m3), mixing 5-9 pts. wt. carbon nanotubes and 4-6 pts. wt. lignocellulose in a vacuum reactor, evacuating pressure inside the reactor to 0.01-0.02 MPa, heating to 180-220 degrees C, stirring at a rate of 180-200 rpm for 20-30 minutes, cooling to 150-160 degrees C, adding 2-4 pts. wt. plasticizer and 2-4 pts. wt. antioxidant, stirring at a rate of 280-300 rpm for 45-55 minutes to obtain a mixture (m4), mixing the mixtures (m1)-(m4) in a mixing furnace at 130-150 degrees C, stirring at a rate of 900-1000 rpm for 80-120 minutes, melt-blending the mixture, extruding into granules using an extruder, drying in an oven for 6-8 hours, and injection molding for 18-22 hours.
