The invention relates to the field of thermoplastic elastomer materials, and discloses a preparation method of a halogenated EPDM/PP rubber-plastic blend, a dynamically vulcanized thermoplastic elastomer, and a preparation method and application thereof. The preparation method of the halogenated EPDM/PP blend comprises halogenating EPDM while blending EPDM and PP. The invention grafts halogen onto the EPDM main chain using an initiator, improving the elongation at break and tensile strength of EPDM/PP TPV materials without affecting the vulcanization rate and crosslink density of EPDM, and preparing a dynamically vulcanized thermoplastic elastomer with a smooth surface and excellent processability.
