NOVELTY - Preparing sulfonated graphene-barium salt powder material, involves slowly adding soluble barium salt solution to the sulfonate dispersion graphene to react, aging, washing, centrifuging and separating. The dry powder material is prepared. USE - Method for preparing sulfonated graphene-barium salt powder material used for anti-static anti-corrosion paint used in oil storage tank and oil pipeline industry. ADVANTAGE - The method is simple and efficient, the powder material preparation in the epoxy resin with low filling amount to form a conductive network, the antistatic coating standard is reached. At the same time, the highly dispersed barsulfonate/graphene composite filler has large sheet structure shape, on the basis of keeping good anti-static performance, it also gives excellent long-term anti-corrosion performance of composite coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing static anti-corrosive paint, which involves: 1. using the sulfonated graphene-barium salt powder material dispersed in acetone to form dispersion liquid, the dispersion liquid sulfonated graphene-barium salt powder material solid content is 0.05-0.5 wt.%; 2. adding film-forming substance to stir, the mass ratio of the epoxy resin and the sulfonated graphene-barium salt powder is 1: 0.01- 1:0.1; 3. adding curing agent, stirring uniformly, curing agent polyamide 65 curing agent or organic amine curing agent, the mass ratio of the epoxy resin and the curing agent is 1:0.3- 1:1.2; 4. and, solidifying at room temperature for at least 24 hours to obtain the anti- static anti-corrosion coating.
