▎ 摘 要
NOVELTY - Composite sliding bearing comprises an open cell foam metal (5), a functionalized graphene layer electrodeposited on a surface of the open cell foam metal, where the modified polyetheretherketone is filled in the pores of metal foam. The modified polyetheretherketone is composed of 60-70 pts. wt. modified polyetheretherketone, 5-10 pts. wt. polytetrafluoroethylene, 20-30 pts. wt. basalt fiber after surface modification by coupling agent, 5-10 pts. wt. graphite and 0.8-1.2 pts. wt. antioxidant. After being extruded at a temperature of 360 to 390 degrees C, the coupling agent is a high temperature resistant phenylimide silane, and the amount is 0.2-1.5 wt.% of the mass of the basalt fiber. The ether ether ketone is filled into the pores of the open-cell foam metal by an injection molding process at a temperature of 350-390 degrees C and and an injection pressure of 80 to 120mpa. USE - Composite sliding bearing. DETAILED DESCRIPTION - The functionalized graphene is by the Hummers method is oxidized-peeled-reduced to obtain functionalized graphene. After reduction, graphene is pre-reduced by sodium borohydride, then sulfonated, and then reduced by hydrazine to introduce sulfonic acid on the surface of graphene. The electrodeposition adopts a direct current power source, the graphite electrode is connected to the positive electrode, and the open-cell foam metal is connected to the negative electrode at a concentration of 100 mg to 200 mg/l. An INDEPENDENT CLAIM is included for a method for preparing composite sliding bearing, which involves: (A) depositing a layer of functionalized graphite on a pore surface of an open cell foam metal by an electrodeposition method; (B) loading open-cell foam metal into the injection mold; (C) filling modified polyetheretherketone into the pores of the open-cell foam metal by an injection molding process; and (D) cooling and forming, where modified polyetheretherketone is composed of 60-70 pts. wt. modified polyetheretherketone, 5-10 pts. wt. polytetrafluoroethylene, 20-30 pts. wt. basalt fiber after surface modification by coupling agent, 5-10 pts. wt. graphite and 0.8-1.2 pts. wt. antioxidant and agent is mixed and prepared by extrusion molding at a temperature of 360 to 390 degrees C and after being extruded at a temperature of 360 to 390 degrees C, the coupling agent is a high temperature resistant phenylimide silane, and the amount is 0.2-1.5 wt.% of the mass of the basalt fiber. The ether ether ketone is filled into the pores of the open-cell foam metal by an injection molding process at a temperature of 350-390 degrees C and and an injection pressure of 80 to 120mpa.
