Abstract In order to effectively improve the comprehensive performance of epoxy resin (EP) anti-corrosive coating, a new type of inorganic nanofiller modified sepiolite (OMSEP) was successfully prepared. Then the OMSEP fibers with a content of 0%, 1%, 2%, 3%, 4% and 5% were ad-ded to the pure epoxy resin (EP) anti-corrosive coating for the first time, and the comprehensive performance of OMSEP/EP composite coating and pure EP coating were compared and analyzed. The results show that the addition of the new inorganic nanofiller OMSEP can effectively improve the overall performance of pure EP coatings, and when the amount of OMSEP added is 3%, the adhesion of OMSEP/EP coating is level 1 and the impact resistance is 52 kg·cm, the abrasion amount is only 0.01 g, the impedance modulus in the low frequency region (|Z|0.01 Hz) is three orders of magnitude higher than that of pure EP coating, showing the best mechanical properties and corrosion resistance.
