| 中文摘要: |
| 试验研究防老剂4070对NR胶料性能的影响，并与防老剂4020和3100进行对比。结果表明，防老剂4070/RD并用胶的硫化速度最快，硫化胶的抗屈挠裂口性能、耐热老化性能、耐疲劳性能和耐热水抽提性能最优，耐日光老化性能相当于防老剂4020/RD和3100/RD硫化胶。 |
| 英文摘要: |
| The effect of the antioxidant 4070 on the properties of NR compound was investigated and compared to those of antioxidants 4020 and 3100.The results showed that a NR compound with the highest curing rate was obtained by using 4070/RD，its vulcanizate possessed the excellent flex cracking resistance，thermal aging property，fatigue resistance and hot water extraction resistance，and the comparable light aging property to those by using 4020/RD or 3100/RD. |
