摘要：
The curing behavior of silicone rubber modified epoxy/clay nanocomposites was studied using a differential scanning calorimeter (DSC) and an oscillatory rheometer. The nanocomposites were prepared from the reaction of cycloaliphatic epoxy resins, silicone rubber containing amine functional group, anhydride hardener and nano-clay. As the clay content increased until 4 phr, the curing reaction rate increased, the reaction heat decreased, and the gelation time decreased. The isothermal cure results were well matched with the modified Kamal's model. Therefore, it is thought that the overall cure characteristics can be simulated by applying a modified Kamal's model.
