| Abstract: |
| The SBR sponges with high foaming rates were prepared by use of SBR matrix，borate coupling agent modified clay naphthenic oil and foaming agent as additives and the properties of vulcanizates were investigated.The results showed that the viscosity was increased and the curing rate was slowed due to the addition of modified clay； the optimum cure time was extended due to the loading of naphthenic oil.The SBR sponge possessed low density，good softness， high rebound elasticity，excellent buffering and damping property by using 30 phr modified clay and 3.5 phr naphthenic oil. |
