摘　　要：利用等当量粒子反应原理,对聚氨酯树脂体系的主剂与固化剂的配比进行了计算。计算结果表明,聚氨酯树脂体系的主剂与固化剂的配比在100∶（20~26）范围内。通过DSC分析、动态黏度、恒温黏度分析及25℃凝胶时间的测试,确定了固化工艺与黏度符合管道翻衬修复技术的树脂最佳配比为100∶20。为了验证其使用性能,进行了树脂与管壁剥离强度的模拟测试。结果表明,配比为100∶20的聚氨酯树脂粘结强度较高,可满足管道翻衬修复技术的要求。The mixture ratio between host crystal and curing agent of PU resin is calculated by adopting the particle reaction principle based on the same equivalent weight.The results show that the mixture ratio between host crystal and curing agent of PU resin is 100∶20～100∶26.By the analysis of DSC cures,viscosity-temperature cures,viscosity-time cures and the gelatin time under 25℃,the best mixture ratio of 100∶20 is confirmed.In order to test and verify its operational performance,the adhesive strength between the resin and the pipeline wall was simulated and tested.The results show that the adhesive strength of the resin with mixture ratio of 100∶20 is so high that it can meet the requirements of the pipeline lining rehabilitation technology.
