▎ 摘　　要

NOVELTY - Preparing graphene oxide modified styrene-acrylic emulsion comprises mixing the graphene oxide buffer solution and styrene-acrylic monomer mixed solution, ultrasonically dispersing, mixing the obtained emulsion and silane coupling agent and ultrasonically dispersing for the second time, where the component of the graphene oxide buffer solution comprises graphene oxide, water and pH value buffer and the component of the styrene-acrylic monomer mixed solution comprises water, initiator, styrene and acrylate monomer. USE - The emulsion is useful in anticorrosion of cement-based material (claimed). ADVANTAGE - The emulsion has excellent performance and improves the durability of cement-based materials.
