Abstract

The invention discloses a graphene-based anti-corrosive coating material for underwater curing construction and a preparation method thereof. The graphene-based anti-corrosive coating material for underwater curing construction comprises a component A and a component B, wherein the component A is prepared from the following raw materials of modified epoxy resin, epoxy active thinner, nanoparticle / graphene composite material, water-borne phosphate chelating matter, organosilicone resin, and emery; the component B is prepared from the following raw material of cashew nut shell oil-modified phenolic amine resin. The preparation method comprises the following steps of uniformly stirring all components of the component A and the component B; uniformly mixing the component A and the component B according to a weight ratio of (5 to 10):1, so as to obtain the graphene-based anti-corrosive coating material. The graphene-based anti-corrosive coating material and the preparation method have the characteristics that the graphene-based anti-corrosive coating material can be applied to the construction of underwater steel structure surfaces, and be quickly cured under water, and the effect is lasting; by adopting the nanoparticle / graphene composite material in the coating material, the anti-corrosive property is enhanced.

Description

technical field [0001] The invention relates to an anti-corrosion coating material, in particular to a graphene-based anti-corrosion coating material for underwater curing construction and a preparation method thereof. Background technique [0002] The rapid development of my country's marine economy is inseparable from concrete structures and steel structures that have been immersed in seawater for a long time, such as port terminals, drilling platforms, cross-sea bridges, underwater pipelines, ships, wind power towers, etc. Because these facilities are located in the seawater full immersion area and tidal range area all the year round, they are often subject to marine corrosion and marine pollution, which brings huge economic and safety risks. In order to maintain these facilities, an anti-corrosion coating that can be applied underwater and quickly solidifies to form a film is needed. [0003] Graphene has an excellent sheet structure, which can prevent the corrosive med...
