Abstract

The epoxidized hydroxyl-terminated polybutadiene(EHTPB)/H12MDI polyurethane elastomer were prepared by cure cross-linking reaction between EHTPB and H12MDI.The optimum reaction temperature was investigated by using DSC extrapolation.The mechanical properties of curing products were tested to study other optimum curing parameters,such as reaction time,use amount of H12MDI and chain extender BDO,as well as epoxidized value of EHTPB.Mechanical properties of HTPB/H12MDI curing products were compared with those of EHTPB/H12MDI curing products under the same conditions.The results show that EHTPB/H12MDI curing products have better mechanical properties,and the optimum process conditions of EHTPB/H12MDI polyurethane are obtained.
