摘　　要：为了解决当前维修施工中存在的粘结强度与耐疲劳性不理想问题,该文对聚氨酯粘合剂材料在建筑维修施工中的应用展开探索,依据聚氨酯粘合剂材料的固化机理,对聚氨酯粘合剂的制备方法进行了阐述。并分析材料动态粘弹性,从而完成性能指标统计。随后明确渗漏点,并清理干净切割裂缝,在凹槽中注入单组分聚氨酯密封胶后,完成底涂施工,最后通过蓄水试验评估施工质量。仿真实验表明,聚氨酯粘合剂材料不仅增加了建筑基面之间的粘结强度,而且具有比较有效的通气度。Based on the curing mechanism of polyurethane adhesive materials,the method of obtaining polyurethane adhesive is implemented.Then,the leakage point was determined,the cut cracks were cleaned,one component polyurethane sealant was injected into the groove,the bottom coating was finished,and the construction quality was evaluated by water storage test.The simulation results show that the polyurethane binder not only increases the bonding strength between the building substrates,but also has a more effective ventilation.
