Water-based graphene anticorrosive paint and preparation method thereof

The invention discloses a water-based graphene anticorrosive coating and a preparation method thereof. The water-based graphene anticorrosive coating comprises epoxy resin, functionalized graphene, a dispersing agent, a preservative, a curing agent and a solvent, the functionalized graphene is prepared by reacting a modified copolymer with phosphorylated graphene oxide; the modified copolymer has a structure as shown in a formula A, and a: b: c = (10-15): (5-8): (3-5). According to the water-based graphene anticorrosive paint provided by the invention, the functionalized graphene is added into the water-based epoxy resin, and the components such as the dispersing agent, the preservative and the curing agent are compounded, so that the prepared paint has good dispersity and excellent stability, and the anticorrosive capability of the paint can be remarkably improved. # imgabs0 # 本发明公开了一种水性石墨烯防腐涂料及其制备方法，所述水性石墨烯防腐涂料包含环氧树脂、功能化石墨烯、分散剂、防腐剂、固化剂和溶剂；所述功能化石墨烯通过改性共聚物与磷酸化氧化石墨烯反应制得；所述改性共聚物具有如下式A所示结构，其中，a：b：c=（10-15）：（5-8）
