This invention discloses a polypropylene composition, its preparation method, and its applications, belonging to the field of polymer material modification technology. The polypropylene composition comprises a matrix polypropylene, a second polypropylene, a polyolefin elastomer, a masterbatch A composed of bismaleimide monomers, a third polypropylene, zirconium phosphate, and a silane coupling agent, masterbatch B. This invention achieves excellent interfacial compatibilization and controllable crosslinking within the polyolefin elastomer phase through the reaction of maleic anhydride and dodecyl diamine with bismaleimide monomers. Simultaneously, ball-milled modified zirconium phosphate provides efficient heterogeneous nucleation, significantly improving the crystallinity of the matrix. The resulting polypropylene composition better balances rigidity and toughness, broadening the application prospects of polypropylene materials in high-performance fields.
