Abstract

Study on isocyanate-terminated prepolymer prepared by the reaction of toluene diisocyanate (TDI) with the hydroxy of epoxy resin. By the characteristics that isocyanate-group reacts with active hydrogen groups easily, the prepolymer could be as a curing agent for substance with active hydrogen groups like coal tar. IR spectra showed that the modification was achieved by cross-linking the hydroxy of epoxy resin and the isocyanate of TDI, but epoxy group had no change. In self-made coal tar coatings, the remaining isocyanate-groups played a curing agent role linking coal tar and epoxy resin. Tafel test showed the films with prepolymer was more corrosion resistance, combined the characteristics of the epoxy resin and coal tar.
