摘要：环保税全面实施，传统溶剂型防腐涂料已不能适应国内新形势的要求。 水性工业涂料如何提高
产品性能、优化产品涂装、拓展应用范围等成为行业难题。 水性聚脲纳米重防腐涂料已在化工重防腐管廊
项目等 8 个项目推广应用。 本文重点以案例分析水性聚脲纳米涂层应用于新建化工金属管廊、二次维修金
属管廊、金属釜外壁、金属釜内壁等工况环境，探究不同施工方式、处理方式对涂层性能的影响，应用于案
例的涂层的防腐防护性能表现突出。

Abstract:* The environmental protection tax has been fully implemented, and the traditional
solvent -based anti -corrosion coatings have been unable to meet the requirements of the new
domestic situation. How to improve the performance of the waterborne industrial coatings, optimize
coating process and expand application range have been regarded as industry problems. The
waterborne polyurea nano -structured heavy -duty anti -corrosion coating has been promoted and
applied in 8 projects including the chemical heavy-duty anti-corrosion pipe gallery project. In this
paper, several case study of waterborne polyurea nano-structured coating applied in newly-built
chemical metal pipe gallery, repaired metal pipe gallery, outer wall and inner wall of the metal kettle
and other working conditions are analyzed. Meanwhile, the effects of different construction methods
and treatment methods on the properties of the coating. The results show that the anti -corrosion
involved in case study has good protection performance.
