▎ 摘  要

NOVELTY - Graphene static conductive anticorrosive coating without solvent comprises A component and B component. The component A comprises 10-30 pts. wt. epoxy resin, 2-10 pts. wt. modified resin, 2-10 pts. wt. active diluting agent, 0.5-3 pts. wt. anti-settling agent, 1-5 pts. wt. dispersant, 0.1-1 pts. wt. de-foaming agent, 10-30 pts. wt. titanium pigment, 20-40 pts. wt. barium sulfate, 20-40 pts. wt. micaceous iron oxide ash, 0.1-1 pts. wt. graphene, and the component B comprises 100 pts. wt. curing agent. USE - The graphene static conductive anticorrosive coating without solvent is useful for corrosion prevention of petroleum pipeline or storage tank. ADVANTAGE - The graphene static conductive anticorrosive coating without solvent: has the performance of conducting static electricity and anticorrosion, and also has zero VOC, and can reach 200-400 um in one film formation, which greatly improves the protective performance of the coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene static conductive anticorrosive coating without solvent comprising (1) adding epoxy resin into the jacket reaction vessel drying and cleaning, 2-10 pts. wt. modified resin, active diluting agent, stirring speed is 600-1200 revolutions per minute, stirring for 10-30 minutes, stirring uniformly, adding anti-settling agent, dispersing agent, antifoaming agent, titanium pigment, barium sulfate, stirring speed is 1000-1500 revolutions per minute, stirring for 30-60 minutes, grinding by sand mill, obtaining slurry, the slurry is at a stirring speed of 500-800 revolutions per minute, adding micaceous iron oxide ash, graphene, and mixing uniformly to obtain A component, and (2) adding curing agent to obtain the second component, and (3) mixing the A component and B component to obtain the coating.
