Beschreibung
Zusammenfassung:	The present invention relates to the technical field of polypropylene materials, and provides a polypropylene microsphere and a preparation method therefor, a 3D printing raw material, and a use. The polypropylene microsphere comprises 0.2 wt%-10 wt% of a structural unit derived from ethylene and 90 wt%-99.8 wt% of a structural unit derived from propylene, wherein a melting heat absorption curve of the polypropylene microsphere is obtained by means of a differential scanning calorimeter (DSC), and a half-peak width (Wm) of the melting heat absorption curve of the polypropylene microsphere is 4-10 °C. According to the polypropylene microsphere of the present invention, the crystallization sequence distribution of the polypropylene microsphere is uniform, and when the polypropylene microsphere is used for 3D printing, 3D printing melting is uniform, a product is good in performance, and the polypropylene microsphere has an industrial application prospect.
