NOVELTY - Economical graphene slurry containing modified epoxy zinc-rich primer comprises component A and component B with mass ratio of 5-10:1; the component A comprises medium solid containing high molecular weight epoxy resin, high solid containing low molecular weight epoxy resin, organic solvent, bentonite, gas phase silicon dioxide, plasticizer, polyvinyl butyral solution, zinc powder, ferro-phosphorus powder and graphene slurry; the component B comprises cashew nut shell oil modified amine curing agent, or further comprises an organic solvent. USE - Used as economical graphene slurry containing modified epoxy zinc-rich primer. ADVANTAGE - The primer is environmentally friendly, has reduced cost of more than 15%, has salt-mist resistant performance, adhesion performance, and strong shock resistance property. The method has friendly production process, is simple, does not require sand grinding process, is economical and is suitable for industrial scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing economical graphene slurry containing modified epoxy zinc-rich primer comprising (i) preparing component A by providing medium solid containing high molecular weight epoxy resin, high solid containing low molecular weight epoxy resin, and organic solvent, mixing and stirring uniformly to form a clear solution under the condition of stirring, then adding bentonite, gas phase silicon dioxide, plasticizer, polyvinyl butyral solution, zinc powder and ferro-phosphorus powder, dispersing, finally, under the stirring state, adding graphene slurry, and dispersing to obtain finished product, (ii) preparing component B by mixing cashew nut shell oil modified amine curing agent and organic solvent uniformly to obtain mixture, and (iii) when using, mixing the component A and component B according to the mass ratio of 1:5-10 to obtain the product.
