The present invention discloses an anti-aging foamed polypropylene material and a preparation method thereof, relating to the technical field of polymer materials. In the preparation of the anti-aging foamed polypropylene material, N-hydroxyacrylamide is grafted onto polypropylene by free radical initiation, and then reacted with acetic anhydride to prepare modified polypropylene; modified lignin is prepared by reacting lignin, formaldehyde and bis(3-aminopropyl)phenylphosphine; modified polypropylene, modified lignin, azodicarbonamide and nano-zinc oxide are uniformly mixed, extruded and calendered into a film through a twin-screw extruder, and then foamed to obtain the anti-aging foamed polypropylene material. The anti-aging foamed polypropylene material prepared by the present invention has good porosity, tensile strength, anti-aging performance and flame retardancy.
