| Abstract: | A quickly curing repairing adhesive for conveyer belts at room temperature was successfully synthesized by using a TDI-PEBA(polyethylene and butylene glycol adipate) polyurethane prepolymer as the component A,a polyols and a chain extender as the component B,and 540 resin as the component C.Its using properties are:working life of 10 min,surface drying time of 2 h,complete curing time of 168 h,tensile strength of 11 MPa,and breaking elongation of 300%~400%.The hardness of the cured was near that of the conveyer belts and its medium resistance was excellent.The adhesive is suitable for quickly repairing of conveyer belts. |
