摘要： The present invention provides a method for preparing polyolefin resin powder, comprising the following steps: a) heating a polyolefin resin to dissolve in an organic solvent with a solubility parameter smaller than or equal to that of the polyolefin resin to obtain a polyolefin resin solution; b) cooling the polyolefin resin solution, so that a solid precipitates out to obtain a solid-liquid mixture; c) optionally adding an additive to the solid-liquid mixture and mixing; d) performing solid-liquid separation and drying to obtain polyolefin resin powder for selective laser sintering, wherein the difference between the solubility parameter of the organic solvent and the solubility parameter of the polyolefin resin falls within 0-20% of the solubility parameter of the polyolefin resin. The polyolefin resin powder obtained in the present invention has good oxidation resistance and powder flowability, a moderate size, a smooth surface, a suitable bulk density, and appropriate dispersibility and particle size distribution. The polyolefin resin powder is especially applicable to a selective laser sintering method.
