Abstract Located on coastal areas, facilities and pipelines serviced at high temperature will encounter from humid-hot corrosive environments for a long period, which can lead to deterioration of their thermal insulation coating. In this study, nano-ZrO2 particles modified corrosion-resistant and thermal insulated epoxy coatings were prepared and characterized in terms of salt water resistance, salt fog resistance, cold and heat shock resistance and thermal insulation performance. The results showed that the corrosion resistance and thermal insulation stability of nano-modified coatings in corrosive environments could be significantly improved. The improvement effect was the best when 3% nano- ZrO2 particles was added, but the ideal protective performance could not be achieved when the content was too small or too much.
