| 中文摘要: |
| 对防老剂DTPD的特点和质量进行评述，分析其3种有效成分含量。防老剂DTPD作为后效型对苯二胺类防老剂，耐抽出性能较好，长效老化防护效果突出，是轮胎工业重要且具有很好发展前景的防老剂品种。随着行业标准的正式实施，产品质量得到规范和提升，但不同企业和生产工艺的防老剂DTPD中3种有效成分含量有差异。有效成分N，N′-二邻甲苯基对苯二胺和N-苯基-N′邻甲苯基对苯二胺含量高的防老剂DTPD具有更好的后效防护作用。 |
| 英文摘要: |
| The characteristics and quality of antioxidant DTPD were reviewed，and the content of three active ingredients were analyzed.As a post-effect type p-phenylenediamine antioxidant，DTPD had good extraction resistance，outstanding long-term aging protection effect，and was an important and promising antioxidant in tire industry.With the formal implementation of industry standard，the quality of antioxidant DTPD had been standardized and improved，but the content of three active ingredients in antioxidant DTPD of different enterprises and production processes was different.Antioxidant DTPD with high content of active ingredients N，N′-di-o-methylphenyl-p-phenylenediamine and N-phenyl-N′-o-methylphenyl-p-phenylenediamine had better post protective effect. |
