Abstract
TPU was activated by hexamethylene diisocyanate (HDI) after the treatment of oil removing and cleaning the surface, and form free isocyanate groups (-NCO) on both sides. Then the ureido (-NHCONH) was formed by the reaction of amino groups (-NH2) of MCDEA and the free -NCO groups above. In the research, the tensile properties of TPUs modified by MCDEA MOCA and DMTDA respectively, were examined. The result show that non-toxic MCDEA was satisfactory to modify TPU, the best propertie was realized under the blend of TPU and MCDEA with ratio of 1∶7.关键词
