Preparation method of aqueous anticorrosive and fireproof integrated coating

The invention provides an aqueous anticorrosive and fireproof integrated coating. The aqueous anticorrosive and fireproof integrated coating is prepared by integrally adding graphene oxide and sodiumtripolyphosphate to an aqueous epoxy resin by a silane coupling agent. A preparation method of the coating comprises the specific preparation steps of (1) mixing sodium tripolyphosphate, xylene and the silane coupling agent, reacting the mixture, and then washing and drying the mixture to obtain modified sodium tripolyphosphate; (2) mixing modified sodium tripolyphosphate, graphene oxide and deionized water, reacting the mixture, and then washing and drying the mixture to obtain integrated sodium tripolyphosphate/graphene oxide; (3) mixing the integrated sodium tripolyphosphate/graphene oxide,deionized water and the aqueous epoxy resin to obtain a mother solution; (4) mixing the mother solution and other auxiliaries in proportion to obtain the aqueous anticorrosive and fireproof integrated coating.
