Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, in particular the invention relates to a water-based epoxy antistatic anti-static oil-resistant anti-corrosion coating for the inner wall of an oil tank and a preparation method thereof. Background technique [0002] In recent years, water-based coatings have been gradually promoted and applied in the petrochemical field, and water-based coatings have been included in the category of heavy-duty anti-corrosion coatings in relevant petrochemical standards. [0003] At present, petrochemical coatings are mainly oil-based and heavy-duty anti-corrosion. Under the current stringent environmental protection policy requirements, my country is in the transition stage of "oil to water". The water-based technology of conductive static anti-corrosion coatings on the inner wall of petroleum storage tanks is in its infancy. It will replace traditional solvent-based static conductive anti-corros...
