摘　　要：长江科学院自主研发的水免疫聚脲混凝土表面防护材料以改性聚天门冬氨酸酯和异氰酸酯为组份,通过结构调控制备得到,其不受所处环境中水的作用而产生劣化,对水具有免疫功能即水免疫性,从而降低服役环境对材料施工和性能的影响,解决了聚脲工程应用关键性问题。该材料通过近10 a来在丹江口水库、南水北调中线高填方渠道、穿黄隧洞、溪洛渡水电站以及尚家河水库等大中型重点工程中的应用,显示出优异的防护效果。在水利水电领域具有较大的开发价值与应用前景,并可向市政、交通、海洋工程等其它基础建设和国民生活领域拓展。The water immune polyurea concrete surface protection material independently developed by Yangtze River Scientific Research Institute is prepared from modified polyaspartic acid ester and isocyanate by adjusting and controlling the molecular structure and aggregate structure.It is not to be deteriorated by water in the environment;that is to say,it is immune to water.Such water immunity reduces the impact of service environment on material performance and construction,and addresses the critical problems in engineering application of polyurea.It has proved excellent application effect in large and medium-sized key projects such as Danjiangkou Reservoir,high-fill canal of middle route of South-to-North Water Diversion Project,Yellow River crossing tunnel,Xiluodu Hydropower Station,and Shangjiahe Reservoir over the past decade.The material is of great development and application value and prospect in the field of water conservancy and hydropower,and is expected to be applied in municipal administration,transportation,marine engineering and other areas of infrastructure and national life.
