Zusammenfassung:	The invention discloses a preparation method of a double bond modified graphene/polyvinylidene chloride heavy-duty coating and relates to the technical field of coatings. The preparation method comprises the following steps of firstly, adopting an improved Hummers method to prepare a graphene oxide aqueous dispersion; then, utilizing double bond-contained silane coupling agent to modifying graphene oxide, and then using L-ascorbic acid to reduce graphene oxide to prepare a modified graphene aqueous dispersion; and then, performing in-situ emulsion polymerization on the modified graphene aqueous dispersion with vinylidene chloride and acrylate monomer to prepare the double bond modified graphene/polyvinylidene chloride heavy-duty coating. In the prepared double bond modified graphene/polyvinylidene chloride heavy-duty coating, the compatibility of an inorganic component and an organic component are relatively good; and in addition, modification of double bond modified graphene to a polyvinylidene chloride emul
