Zusammenfassung:The invention discloses a preparation method of an alloy type creep-resistant fluorine-containing thermoplastic elastomer. The alloy type creep-resistant fluorine-containing thermoplastic elastomer is prepared from the following raw materials: 100 parts of a thermoplastic elastomer, 0.05-5 parts of an initiator, 1-20 parts of GMA, 30-70 parts of PVDF, 5-50 parts of EGMA, 0.05-5 parts of dicarboxylic acid or anhydride, 0-5 parts of a catalyst and 0.01-5 parts of an antioxidant. The preparation method comprises the following steps: carrying out chemical treatment on a thermoplastic elastomer by using an initiator and GMA to prepare a modified thermoplastic elastomer, blending the modified thermoplastic elastomer with PVDF, EGMA, dicarboxylic acid or anhydride, adding a catalyst to generate a dynamic covalent bond, and finally carrying out hot press molding by using a press vulcanizer. The creep resistance of the material is improved by constructing dynamic covalent bonds, so that the material has good machinabi
