NOVELTY - Preparing hydrochloric acid-hydrogen sulfide corrosion-resistant and high-temperature resistant coating comprises using 6-amino-2-picolinic acid, graphene nanosheet, organic resin, polyvinyl polyamine, trimethylolpropane trimethacrylate, diethylene glycol butyl ether, organosiloxane resin, dispersant, anticorrosive filler, leveling agent, defoamer, and water as raw materials firstly subjecting 6-amino-2-picolinic acid and graphene nanosheet to esterification reaction to obtain 6-amino-2-picolinic acid graphene ester, combining organic resin with polyvinyl polyamine and trimethylolpropane trimethacrylate, reacting to obtain a crosslinked modified organic resin, finally functionalizing the obtained 6-amino-2-picolinic acid graphene ester with the crosslinked modified organic resin to obtain the organic resin material functionalized with graphene 6-amino-2-picolinate, then mixing and stirring with the remaining components to obtain the coating. USE - The method is useful for preparing hydrochloric acid-hydrogen sulfide corrosion-resistant and high-temperature resistant coating.
