NOVELTY - Method for preparing anticorrosive material of graphene grafted modified acrylic resin involves (a) adding graphene oxide to thionyl chloride, placing in a water bath reaction device, heating to 65-75 degrees C in a nitrogen atmosphere, (b) adding graphene acyl chloride and 2-mercaptoethanol to the dichloromethane solvent, ultrasonically dispersing, adding the accelerator triethylamine, heating in a nitrogen atmosphere, and (c) adding methyl acrylate, methyl methacrylate, n-butyl acrylate and mercapto functionalized graphene to the distilled water solvent, ultrasonically dispersing to form a polymerized monomer solution, taking 1/5 volume of polymerized monomer solution and heating, slowly adding ammonium persulfate solution dropwise, adding the remaining 4/5 volume of polymerized monomer solution, dissolving the product in an acetone solvent and pouring into the surface of the tinplate for curing to form a film to obtain the product. USE - The method is used for preparing anticorrosive material of graphene grafted modified acrylic resin. ADVANTAGE - The method improves the compatibility of graphene and acrylic resin, reduces the agglomeration between graphene nanoparticles, has excellent mechanical properties, improves the tensile strength and flexural modulus of the material, and has excellent salt spray resistance and anti-corrosion performance.
