Preparation and Performance Analysis of Waterborne Epoxy Antistatic Oil-resistant Anticorrosive Coatings
Using waterborne epoxy emulsion and waterborne epoxy curing agent as film-forming materials,conductive mica powder as conductive filler,anticorrosive pigments,fillers and additives,waterborne epoxy electrostatic conductive oil-resistant anticorrosive coatings with excellent electrostatic conductivity and anti-corrosion performance were prepared.The influence of the ratio of waterborne epoxy curing agent and waterborne epoxy emulsion on the film performance,and the influence of the type and amount of conductive fillers on the conductivity of the coatings were discussed.The ratio of anti-rust pigment and filler and resin in the formula of waterborne epoxy electrostatic conductive oil-resistant anticorrosive coatings was determined by orthogonal test,and the influence of different coatings thickness on the change of surface resistivity was analyzed.The results showed that when the ratio of waterborne epoxy curing agent and waterborne epoxy emulsion was epoxy/amine hydrogen equivalent ratio of 1.2,and the content of conductive mica powder was about 18%,the anti-static and anti-corrosion properties of the coatings were optimized,making them suitable for the internal anti-corrosion and electrostatic protection of oil storage tanks,oil pipelines,and transportation oil tanks in the petrochemical industry.
