| Abstract: |
| The effects of conventional reinforcing agents（carbon black and silica），montmorillonite（original and OMMT） and salts of unsaturated carboxylic acids（zinc methacrylate and magnesium methacrylate） on the physical properties and hot air aging property of HNBR compounds were investigated，and the microstructure was characterized by SEM，TEM and TGA.The results showed that the conventional reinforcing agents could be dispersed uniformly in rubber matrix，and provided better physical properties but poor air aging property；the reinforcement effect of salts of unsaturated carboxylic acids was the best because of the crosslinking grafted reaction in rubber matrix，and the air aging property increased obviously；the dispersion of MMT and physical properties of HNBR compounds were significantly enhanced by organic modification on MMT，and meanwhile，the composites had excellent hot air aging property. |
