Located on coastal areas,facilities and pipelines serviced at high temperature will encoun-ter from humid-hot corrosive environments for a long period,which can lead to deterioration of their ther-mal insulation coating.In this study,nano-ZrO2 particles modified corrosion-resistant and thermal insulat-ed 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 corro-sion 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 add-ed,but the ideal protective performance could not be achieved when the content was too small or too much.
