| 中文摘要: |
| 通过3种添加工艺将乙二胺四乙酸二钠（EDTA-2Na）、柠檬酸钠（NaCA）和三聚磷酸钠（STPP）3种金属离子钝化剂加入胶清橡胶，研究金属离子钝化剂对胶清橡胶硫化特性、物理性能和热氧老化性能的影响。结果表明：加入金属离子钝化剂对胶清橡胶硫化特性和物理性能影响较小，但能明显提高胶清橡胶的热氧老化性能；NaCA和EDTA-2Na在凝固前加入胶清对提高胶清橡胶热氧老化性能和热稳定性效果更好，STPP则在混炼过程中添加效果更好。 |
| 英文摘要: |
| Three kinds of metallic passivator，including EDTA-2Na，NaCA and STPP，were added into skim rubber through three kinds adding processes.The effect of adding process of metallic passivator on the curing characteristics，physical properties and thermo oxygen aging properties of skim rubber was investigated.The results showed that with metallic passivator，the curing characteristics and physical properties of skim rubber were changed slightly，but the thermo oxygen aging properties were improved significantly.Through adding NaCA or EDTA-2Na before skim serum coagulation，the thermo oxygen aging properties and thermal stability of skim rubber were improved，and better results would be obtained by adding STPP in mixing process. |
