Beschreibung
Zusammenfassung:	The invention belongs to the technical field of sealing strips, and particularly discloses a water turbine movable guide vane end face sealing strip and a preparation method thereof. The sealing strip for the end face of the movable guide vane of the water turbine is of an inverted-T-shaped structure and is prepared from alkylamine functionalized graphene oxide and a pouring type polyurethane prepolymer, the bottom face of the sealing strip makes contact with a sealing groove in the end face of the movable guide vane of the water turbine, the middle of the bottom face of the sealing strip is an arc section, and the two sides of the arc section are horizontal sections. The horizontal section of the sealing strip enables the bottom of the sealing strip to make full contact with the sealing groove, the arc section can guarantee that space allowance exists when the sealing strip is compressed, the sealing compensation effect is achieved, the sealing reliability is improved, and the probability that the sealing st
