| 中文摘要: |
| 采用高效液相色谱法研究天然橡胶硫化胶中新型对苯二胺类防老剂TMPPD的耐水抽出性能，并与常用对苯二胺类防老剂6PPD和IPPD对比。结果表明：在3种防老剂中，防老剂TMPPD的耐水抽出性能最佳，防老剂TMPPD基本不被水抽出；防老剂IPPD的耐水抽出性能最差；防老剂6PPD的耐冷水抽出性能较好，耐热水抽出性能较差。 |
| 英文摘要: |
| In this study，the water extraction resistance of a new p-phenylene diamine antioxidant TMPPD in NR was investigated by high-performance liquid chromatography and was compared with conventional p-phenylene diamine antioxidant 6PPD and IPPD.The results showed that among these three kinds of antioxidants，TMPPD showed the best water extraction resistance that almost no TMPPD was detected after water extraction of the vulcanized rubber containing TMPPD.Antioxidant IPPD showed the worst water extraction resistance.Antioxidant 6PPD had good resistance to cold water extraction，but showed poor resistance to hot water extraction. |
