Abstract

In order to improve the corrosion resistance of anticorrosive coatings and expand the application scope of Iranian rock asphalt, solentless Iranian rock asphalt anticorrosive coatings were prepared throuth a two-component process using the matrix asphalt, Iranian rock asphalt and epoxy resin as film - forming materials with the addtion of fillers, various additives and other components. The anti - corrosion properties of such coatings were studied through AC impedance test and acid, alkali and salt corrosion resistance test. Results showed that when the content of Iranian rock asphalt was 15%, the comprehensive properties of modified asphalt were best. The corrosion resistance of the prepared Iranian rock asphalt anticorrosive coating was much better than that of the petroleum asphalt anticorrosive coating. The corrosion resistance time to acid, alkali and salt immersion was prolonged by more than 10 days. The viscosity of Iranian rock asphalt anticorrosive coating was large at room temperature, and good coating effect was achieved when the coating temperature was about 60 ℃.
