| Abstract: | A non-toxic,low viscosity, longer working life, colorless liquid curing agent has been obtained through modification of hexanediamine by muhifunctional epoxy and the structure is characterized by infrared spectroscopy. The reactivity of this curing agent and the optimal curing agent dosage are also studied by DSC; and then with using the epoxy E44 as the curing epoxy resin, its shear strength, impact strength and thermal properties is discussed. The results indicate that the modified curing agent slightly increases the mechanical and thermal properties, and it greatly reduces the reactivity and enhances its working life. |
