NOVELTY - High elastic wear-resistant polyurethane wheel comprises 44.6-45.6 wt.% polyurethane, 39.4-40.4 wt.% organosilicone rubber, 4.4-5.4 wt.% modifier, and hollow microsphere (remaining). USE - Used as high elastic wear-resistant polyurethane wheel. ADVANTAGE - The polyurethane wheel: can improve the acid and alkali resistance and heat resistance of the polyurethane wheel, can be used normally under the acid and alkali environment and high temperature condition, nano-silicon dioxide and hollow micro-bead to compound, which can improve the bearing performance and compressive strength of the PU wheel, can mix nano silicon dioxide and graphene oxide and compounded, can isolate the agglomeration of graphene oxide, can improve the thermal stability of the PU wheel, adds graphene oxide and nano-alumina, which are mixed and compounded, can realize the high heat-conducting electric insulation performance of PU wheel, can ensure the thermal stability of PU wheel, adds modified agent using nano fiber structure, which can ensure the modified treatment effect of the polyurethane, organosilicone rubber and hollow micro-bead, thus ensure the performance of the PU wheel. DETAILED DESCRIPTION - preparing the polyurethane wheel, comprising (i) polyurethane, organosilicone rubber, hollow micro-bead and modifier raw material in the nano silicon dioxide, carbon nano tube, graphene oxide, nano aluminum oxide, Tween (Polysorbate) 80, polytetrafluoroethylene resin; (ii) taking nano silicon dioxide in the step (i), carbon nano tube, graphene oxide, nano aluminum oxide, Tween (Polysorbate) 80, polytetrafluoroethylene resin into the de-ionized water, performing ultrasonic treatment under water bath for 30-40 minutes, adding electrostatic spinning in the electrostatic spinning process to obtain the modifier; (iii) performing co-ultrasonic treatment for the one-third weight of modifier obtained in the step (ii) and the organosilicone resin in step (i) for 20-30 minutes to obtain the mixed material a; (iv) adding the modifier obtained in the step two and the hollow micro-bead in the step (i) into jet-type jet mill to process, obtaining the mixed material b; (v) adding polyurethane in the step (i), and step (ii) in the rest modifier and in the mixed material a and step (iv) to obtain the mixed material b are added to the mixer at 110-120degrees Celsius, mixing for 30-40 minutes, then performing dynamic vulcanization treatment for 10-20 minutes to obtain the mixed material glue; and (vi) injecting the mixed rubber prepared in the step (v) into the mold through a double-screw injector to obtain the high elastic wear-resistant polyurethane wheel.
