| Abstract: | The reaction of epoxy foam system was studied in detail through DSC and structural rotation viscosimeter. The results on viscosity and curing degree changed with time was discussed. Cooperativity of foaming reaction rate and curing rate was analyzed . The two-step method for preparating epoxy foam was determined initially. It was observed that the epoxy foam plastics displayed excellent synthetical properties. |
