| Abstract: | A one component water-soluble polyurethane grouting material was prepared from polyether polyol of high activation, isocyanate and additives. The influence factor of the various -NCO content of prepolymer,the reaction time and temperature,the variety and mass fraction of catalyst on property of one component water-soluble polyurethane grouting material have been studied. The optimum formula is determined:the reaction temperature of prepolymer is between 80 ℃ and 90 ℃,and the reaction time is 3 h,-NCO content is between 3.0% and 4.5%. A series of high-performance water-soluble polyurethane grouting material were prepared. |
