Modified PP foaming enhanced material and preparation method thereof

The invention belongs to the technical field of macromolecular material modification, and in particular relates to a modified PP (polypropylene) foaming enhanced material and a preparation method thereof. The modified PP foaming enhanced material consists of modified PP particles and foamed masterbatches, wherein the modified PP particles consist of PP, an inorganic mineral filling agent, a toughening agent, short glass fibers, an antioxidant 1010 and a surfactant; and the foamed masterbatches consist of EVA, talcum powder, a foaming agent, a foaming promoter, a crosslinking agent, an assistant crosslinking agent and an antioxidant 1010. The PP is enhanced and modified and then is subjected to chemical foaming, so that the prepared PP foamed material has low density, also has excellent tensile strength, bending strength and impact strength, can be used for replacing parts such as a door plate and an instrument desk on an automobile prepared by non-foamed PP at present, and can achieve the aims of reducing wei
