| 中文摘要: |
| 制备二苯基对苯二胺（防老剂BBPD）、苯基甲苯基对苯二胺（防老剂BTPD）和苯基（二甲基）苯基对苯二胺（防 老剂BXPD）3种二芳基对苯二胺类防老剂，测试其熔点和研究其应用性能，并与市售防老剂DTPD进行对比。结果表明： 3种自制的二芳基对苯二胺类防老剂的熔点高于防老剂DTPD，胶料的加工性能、硫化特性和耐臭氧老化性能与防老剂 DTPD胶料相当，物理性能和耐热氧老化性能比防老剂DTPD胶料好，防老剂BTPD和BXPD胶料的耐屈挠疲劳性能优于防老剂DTPD胶料。 |
| 英文摘要: |
| Three kinds of diaryl-p-phenylenediamine antioxidants，N，N′ -diphenyl-p-phenylenediamine （antioxidant BBPD），N-phenyl-N′ -methylphenyl-p-phenylene diamine（antioxidant BTPD） and N-phenyl-N′ -dimethylphenyl-p-phenylenediamine（antioxidant BXPD） were prepared. The melting points were measured，the application properties were studied，and compared with commercial antioxidant DTPD. The results showed that the melting points of those three self-made antioxidants were higher than that of antioxidant DTPD，the processing properties，curing characteristics and ozone aging resistance of the compound with either of those three antioxidants were similar to those of the compound with antioxidant DTPD，the physical properties and thermal aging resistance were better，and the flex fatigue resistance of the compound with antioxidant BTPD or antioxidant BXPD was better than that of the compound with antioxidant DTPD. |
