Beschreibung
Zusammenfassung:	The invention discloses a one-step method reaction device for thermoplastic polyurethane. The one-step method reaction device comprises a material storage tank, a static metering feeding device, a check valve, a reactor, a valve and a buffering device, wherein all the parts are connected by pipelines; the static metering feeding device is composed of a pneumatic ball valve, a plunger piston cylinder body, a plunger piston and a driving device; the buffering device is composed of a buffering device kettle body, a plunger piston and an oil cylinder. The one-step method reaction device for the thermoplastic polyurethane has the beneficial effects that the metering device is accurate in feeding and has strong adaptability on materials with different viscosities; the one-step reaction device for the thermoplastic polyurethane disclosed by the invention can be used in cooperation with a double-screw extruder with a small length-diameter ratio and can also be used in cooperation with a melt pump, so as to realize co
