摘　　要：通过将密封胶应用到装配式混凝土建筑外墙的拼接处,可以起到一定的防水作用,为了进一步提高密封胶防水效果,现以“聚氨酯密封胶”为研究对象,实验分析聚氨酯密封胶材料的适应性、强度等性能。结果表明:为保证工程施工质量,相关人员要重视对混凝土界面的清洁处理以及缝面的烘干处理,确保缝表面的整洁度和干净性;当干燥处理接收后,方可对聚氨酯材料进行接缝施工操作,最大限度地提高接缝防水性能。Applying sealant to the splices of exterior walls of prefabricated concrete buildings can play a certain waterproof role.In order to further improve the waterproof effect of the sealant,we take“polyurethane sealant”as the research object,and use experimental analysis to comprehensively analyze the adaptability,strength,and other properties of polyurethane sealant materials.The test results show that in order to ensure the quality of engineering construction,relevant personnel should pay attention to the cleaning treatment of the concrete interface and the drying treatment of the joint surface to ensure the cleanliness and cleanliness of the joint surface.After the drying treatment is received,joint construction operations can be carried out on polyurethane materials to maximize the waterproof performance of the joint.It is hoped that effective referencecan be provided for relevant personnel.
