This article provides comprehensive experimental data of two water-swelling materials, water swelling rubber (WSR) and water-swelling polyurethane (WSP). Swelling tests, Dynamic Mechanical Analyzer (DMA) and Scanning Electron Microscope (SEM) were performed. Sealing properties of WSR and WSP were characterized by the data of swelling ratios (S and S), storage moduli (E') and images of micro-damage morphologies. These data can be useful for the prediction of the long-term waterproof performance of water-swelling materials and provide reference for material selection. The data presented herein was used for the article, titled "Laboratory evaluation of long-term sealing behaviors of two water-swelling materials for shield tunnel gasket" [1].
本文提供了两种遇水膨胀材料——遇水膨胀橡胶（WSR）和遇水膨胀聚氨酯（WSP）的全面实验数据。进行了膨胀试验、动态力学分析仪（DMA）测试和扫描电子显微镜（SEM）分析。通过膨胀率（S和S）、储能模量（E'）数据以及微观损伤形态图像对WSR和WSP的密封性能进行了表征。这些数据有助于预测遇水膨胀材料的长期防水性能，并为材料选择提供参考。本文所呈现的数据用于题为《两种盾构隧道密封垫用遇水膨胀材料长期密封性能的室内评价》的文章[1]。
