Water-based graphene corrosion-resistant coating and preparation method thereof

The invention discloses water-based graphene corrosion-resistant coating and a preparation method thereof. The corrosion-resistant coating comprises a coating main agent and a coating additional agent, wherein the coating additional agent comprises water-based epoxy resin and a crosslinking additive; and the coating main agent comprises the following components: a water-based epoxy resin curing agent, a cosolvent A, a cosolvent B, a crosslinking additive, a catalyst, zinc powder and graphene. According to the water-based graphene corrosion-resistant coating and the preparation method thereof,which are provided by the invention, the high conductivity characteristic of the flaked graphene material is utilized and the traditional zinc powder material is combined, so that the specific surfacearea of the graphene can be greatly increased and the use amount of the zinc powder can be greatly reduced under the condition of guaranteeing the corrosion-resistant effect. 本发明公开了种水性石墨烯防腐涂料及其制备方法，所述防腐涂料包含涂料主剂和涂料附剂，所述涂料附剂包含水
