The invention discloses a fragrance type polypropylene composite material and a preparation method thereof. The fragrance type polypropylene composite material comprises the following components in percentage by weight: 48-97.9% of polypropylene, 2-20% of an elastomer, 0-30% of talcum powder, 0.001-0.005% of a flavoring agent and 0.1-2% of an antioxidant. The preparation method comprises the following steps: (1) weighing the components according to the ratio, mixing the polypropylene, the elastomer and the flavoring agent for 1-3 minutes in a high-speed mixing machine, adding the talcum powder and the antioxidant, and further mixing for 1-3 minutes so as to obtain premix; and (2) performing melting extrusion on the premix by using a twin-screw extruder, and performing vacuum granulation, thereby obtaining the fragrance type polypropylene composite material. The fragrance type polypropylene composite material has the advantages that a small amount of the flavoring agent is added, no toxin or harm can be caused, original mechanical properties and sporadic properties such as flavor, condensation, VOC (Volatile Organic Compounds) and the like of the material are not damaged, on the contrary, bad smell of plastic, charring and the like of a high polymer material self can be weakened, pleasant fragrance can be generated instead, and thus the acceptability of the composite material can be improved.
