中文摘要:
      研究了氢氧化镁、氧化锌及硬脂酸对环氧化天然橡胶(ENR)硫化特性、硫化胶的力学性能及老化性能的影响。结果表明：加人2份氢氧化镁可有效地提高ENR的硫化速度、拉伸强度和抗热氧老化性能；氧化锌和硬脂酸对硫化胶网络的完善是不可缺少的。用差示扫描量热法(DSC)比较了几种防老剂(防老剂D，H，WSP，MB，4010，SP)在ENR中的防护效果。结果表明防老剂D的效果最好。以防老剂D与防老剂MB并用，加入2份氢氧化镁、2份硬脂酸和5份氧化锌，不仅可缩短硫化时间，而且可大幅度提高硫化胶的拉伸强度、扯断伸长率和老化系数。
英文摘要:
      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.
