The invention discloses a quality detection method for special propylene material, comprising the specific steps of (1) measuring melt-mass flow rate MFR1 when the special propylene material has a load of 5 kg; (2) measuring melt-mass flow rate MFR2 when the special propylene material has a load of 2.16 kg; and (3) calculating distribution index n, i.e., lg MFR1/LG MFR2, wherein the special propylene material is prepared by using the controllable rheological method. The quality detection method for the special propylene material has the advantages of good simplicity and high speed; a quantitative analytical method is provided for detecting the odor of the special propylene material prepared by using the controllable rheological method, and the method is applicable to the quality control in industrial amplified production.
