Abstract
The invention relates to a preparation method of a polypropylene enhanced and toughened composite material. The preparation method comprises: drying polypropylene, glass fibers and nano calcium carbonate; adding a toughening agent and stirring and mixing; fusing, extruding and granulating a mixture on a twin-screw extruder; then, drying a granulated material; finally, carrying out injection molding on the dried material to obtain the enhanced and toughened composite material. By modifying the polypropylene through the polypropylene, the glass fibers and the nano calcium carbonate, the prepared material can be enhanced and toughened through the glass fibers and the toughening agent, and the nano calcium carbonate can further improve the strength of the material, so that the strength of the composite material provided by the invention is greatly improved and an application range is relatively wide.
