摘　　要：针对海洋湿态热腐蚀环境,制备了纳米改性环氧耐蚀隔热涂层;并探究腐蚀过程中涂层的耐盐水、耐盐雾、抗冷热冲击及隔热性能等变化特征,分析腐蚀环境中纳米ZrO_(2)提高环氧隔热涂层耐腐蚀性与隔热性能的关联性。研究表明,纳米改性涂层在腐蚀环境中的耐蚀与隔热稳定性得以显著提升,其中3%ZrO_(2)添加量时,改善效果最好,而含量过少、过多时不能达到理想的防护性能。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-ZrO_(2) 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-ZrO_(2) particles was added,but the ideal protective performance could not be achieved when the content was too small or too much.
