NOVELTY - Preparation method of graphene oxide modified epoxy resin coating involves pretreating the substrate, placing the substrate in a constant temperature drying oven to dry. Adding epoxy resin into a container, adding graphene oxide, then mechanically stirring and ultrasonically dispersing, adding solvent and auxiliary agent to the container respectively, ultrasonically dispersing for 2 hours, and centrifuging to remove graphene agglomerates, Adding carbon black and talc respectively, stirring evenly to obtain coating. Adding a curing agent to the coating, stirring mechanically until it is completely uniform, spraying the coating on the cleaned substrate sample, then drying in a drying oven, and then solidifying at room temperature. USE - Preparation method of graphene oxide modified epoxy resin coating used for pipe. ADVANTAGE - Different amounts of graphene oxide (GO) are added into epoxy resin, so that a GO modified epoxy resin coating is prepared and is subjected to industrial-grade physical and chemical performance test and finally selecting 1 wt.% of GO as the optimum content for preparing the modified coating, so that the obtained modified coating has the strongest adhesive force and wear resistance and better corrosive liquid resistance. Graphene oxide modified epoxy resin coating also provides a certain data basis for industrial production. The technical parameters such as spraying time, spraying paint quantity, curing temperature, curing time, coating viscosity and the like are determined, and data support is provided for industrial production of the industrial grade GO modified epoxy resin coating.
