NOVELTY - Preparing graphene/basalt heat-conductive anti-metal corrosion coating involves adding a bisphenol A epoxy resin, a graphene/basalt composite powder to an aqueous acetone solution, stirring at 300-400 revolutions per minute for 1-2 hours, adding nano titanium dioxide and silane coupling agent and stirring for 30-60 minutes, adding antifoaming agent and emulsifier to continue stirring until the slurry is completely dispersed to obtain the A component. The method for preparing the graphene/basalt composite powder includes dissolving sodium alginate in deionized water to obtain an aqueous solution of sodium alginate. The basalt scales were added to absolute ethanol, stirred at 150-200 revolutions per minute for 10-20 minutes on a magnetic stirrer, and then ultrasonically shaken to obtain a dispersion. The epoxy silane coupling agent and deionized water are mixed, and then added dropwise to the dispersion to stirring the reaction for 10-20 minutes. USE - Method for preparing graphene/basalt heat-conductive anti-metal corrosion coating. ADVANTAGE - The method enables to prepare graphene/basalt heat-conductive anti-metal corrosion coating has block the corrosion of chloride ions, has better heat conduction and heat dissipation effect, and has avoids adverse effects on the hull itself and the coating. DETAILED DESCRIPTION - Preparing graphene/basalt heat-conductive anti-metal corrosion coatinginvolves adding a bisphenol A epoxy resin, a graphene/basalt composite powder to an aqueous acetone solution, to 300-400r /min is stirring for 1-2 hours, adding nano titanium dioxide and silane coupling agent and stirring for 30-60 minutes, adding antifoaming agent and emulsifier to continue stirring until the slurry is completely dispersed to obtain the A component. The method for preparing the graphene/basalt composite powder includes dissolving sodium alginate in deionized water to obtain an aqueous solution of sodium alginate. The basalt scales were added to absolute ethanol, stirred at 150-200 revolutions per minute for 10-20 minutes on a magnetic stirrer, and then ultrasonically shaken to obtain a dispersion. The epoxy silane coupling agent and deionized water are mixed, and then added dropwise to the dispersion to stirring the reaction for 10-20 minutes. The aqueous solution of sodium alginate is added dropwise, and reacted at 30-40 degrees C for 1-3 hours, and the modified basalt is obtained by centrifugation, filtration, and dry bathing. The modified basalt and graphene are added to deionized water, ultrasonically stirred, and centrifuged, filtered, and dried to obtain a graphene/basalt composite powder, adding a curing agent, a UV absorber to ethyl acetate, stirring and mixing to obtain a B component, mixing the A component with the B component and stirring uniformly to obtain a graphene/basalt anti-metal corrosion coating.
