摘　　要：采用聚醚多元醇、甲苯二异氰酸酯(TDI)、3,3'-二氯-4,4'-二氨基二苯基甲烷(MOCA)等制备了无溶剂遇水膨胀液体橡胶止水带,利用邻苯二甲酸二丁酯(DBP)代替有机溶剂使用避免了溶剂的挥发,实验表明,止水带最佳的配比为:m(聚醚D2802)∶m(S505)=1∶4,DBP用量为15%,填料用量为15%,经2年的施工应用未出现漏水现象。A kind of solvent-free water swellable liquid rubber water-stop was prepared,with polyether polyol,TUl, and MOCA. The organic solvent was replaced by DBP,which can avoid the volatilize of solvent. The optimum conditions for water-stop are polyether m（D2802）：m（S505）=1：4;dosage of DBP of 15%：dosage of packing materials of 15%. The application in two years shows that the water leakage has not happened.
