摘　　要：涂层体系性能对城市污水混凝土构筑物的防水和防腐起到重要作用。针对涂层体系的服役特点,选用了11种不同涂层体系,对其耐候性、耐湿热、耐碱性、耐磨性以及干湿基面施工的涂层和混凝土试件的耐酸性能进行了对比。结果表明,改性聚脲涂层体系的综合性能较好,可为污水混凝土构筑物防水防腐工程的设计选材提供参考。The performance of coating system plays an important role in the waterproofing and anti-corrosion of urban sewage concrete structures.According to the service characteristics of the coating system,11 different coating systems are selected to compare their weather resistance,wet heat resistance,alkali resistance,wear resistance,as well as the acid resistance of the coating layer constructed on dry and wet substrates and the concrete specimen.The results show that the comprehensive performance of the modified polyurea coating system is good,which can provide a reference for the design and material selection of waterproofing and anti-corrosion engineering of sewage concrete structures.
