| Abstract: | Two-component PU adhesive was prepared for pipeline repairment in a damp environment.The DSC was used to monitor the cure-reaction process of the adhesive and the water resistance was tested.Multiple field data showed that heat of cure-reaction was 297.4 J/g with the curing temperature at 86.5 ℃.The shear strength of the adhesive decreased 2.2 MPa soaked in water for 15 days with temperature at 22±1 ℃.The adhesive had good water resistance. |
