| Abstract: |
| The influence of magnesium hydroxide，zine oxide and stearic acid on vulcanization behavior，mechanical properties and aging properties of ENR was investigated.The result showed that the curing rate，tensile strength，and thermal and oxidative aging resistance of ENR compound increased significantly by addition of 2 parts of magnesium hydroxide；zine oxide and stearic acid were essential to develop a perfect network.The effect of some antioxidants was compared in ENR compounds with DSC.The best result was obtained with antioxidant D.The vulcanizing time decreased，and the tensile strength，the elongation at break and the aging coefficient of the vulcanizate increased when antioxidant D in combination with MB，2 parts of magnesium hydroxide，2 parts of stearic acid and 5 parts of zine oxide were used in ENR compound. |
