The present invention discloses a biodegradable polypropylene non-woven fabric and a preparation method thereof, belonging to the technical field of biodegradable polypropylene non-woven fabrics. The preparation method comprises: preparing biodegradable masterbatch, preparing anti-aging masterbatch, mixing, spinning and drafting. The preparation of biodegradable masterbatch comprises: adding polypropylene, polycaprolactone, erucamide, maleic anhydride-grafted polypropylene, first modified cellulose nanocrystals, second modified cellulose nanocrystals, stearic acid and 3-aminopropyltrimethoxysilane into a high-speed mixer for uniform mixing, then adding the mixture into a twin-screw extruder for melt extrusion and pelletizing to obtain biodegradable masterbatch. The present invention can improve the degradability of the biodegradable polypropylene non-woven fabric, and enhance the strength, elongation at break, spinnability, UV resistance, high temperature resistance and aging resistance of the non-woven fabric.
