| Abstract: |
| The influence of silica level on the rheology，elastic memory，curing behaviour，equilibrium stress-strain and dynamic mechanical properties of siliea-reinforced ENR was studied.The test result showed that silica-reinforced ENR was a non-Newtonian fluid；the extrusion swelling decreased，the vulcanization rate and the hysteresis 1oss increased as the level of silica increased；the extrusion swelling increased as the shear rate increased.It was indicated with TEM that the dispersion of sillca in ENR compound improved significantly when a silane coupling agent was added into the compound. |
