Epoxy resin waterborne anticorrosive and antistatic coatings have been widely used in many fields such as oil storage tanks and oil pipelines.The modified expanded graphite was added into epoxy resin waterborne antistatic coating to prepare high performance antistatic coating.The results proved that:when the modification of expanded graphite content in the coating was 0.5%,the mechanics properties of the coating was not affected.At the same time,coating resistivity was lowered to 1×108Ω,met the requirements of antistatic national standards.The corrosion resistance of the coating was enhanced,and its resistance to 3% NaCl solution immersion shown salt resistance extended to 5d.Coating resistance to 10% NaOH solution extended to 21d,acid resistance was improved significantly.
