| 摘 要： | 通过示差扫描量热法分析(DSC)研究了芳香胺改性双氰胺/环氧树脂E-44体系的固化反应,并探讨了反应的机理。结果表明,芳香胺改性双氰胺对环氧树脂E-44具有较高的固化反应活性,反应表观活化能明显降低,固化反应可以在中温进行。其固化反应机理与未改性的双氰胺环氧体系不同。

| Abstract: | Curing reaction and mechanism of epoxy resin E-44/dicyandiamide modified by aromatic amine system were studied by differential scanning calorimetry(DSC).The experimental results showed the modified dicyandiamide had excellent curing characteristic for epoxy resin E-44,and apparent activation energy of curing reaction was decreased appreciably,and curing reaction could be carried out at moderate temperature.Its curing reaction mechanism was different with common dicyandiamide /epoxy resin E-44. |
