The invention discloses a polypropylene composition which comprises, by weight parts, 100 parts of polypropylene, 10-30 parts of basic magnesium sulfate whisker, 0.1-1.0 part of foaming agent, 0.5-1.5 parts of smell adsorbent and 10-30 parts of flexibilizer. By simultaneously adding basic magnesium sulfate whisker and foaming agent of a specific content, compared with the situation that only basic magnesium sulfate whisker is added, the weight of a workpiece can be greatly reduced while the comprehensive mechanical property is not reduced, and thus the lightweight requirements of an automobile are met. By adding the smell adsorbent of a specific content and adopting single vacuum design of a twin-screw extruder, it is guaranteed that the vacuum degree requirements are not larger than -0.08 bar, micromolecular volatile matter can be pumped away, and the devolatilization effect is improved obviously. The prepared polypropylene composition is low in smell and emission characteristics, the lightweight requirements of the automobile and low-smell low-emission performances of automobile interior part materials can be met, and the application prospect is wide.
