摘要
以天然橡胶(NR)硫化胶为例,采用高效液相色谱法研究新型防老剂TMPPD在硫化胶中的耐迁移性能,并与防老剂6PPD和IPPD进行对比。结果表明:随着迁移时间延长,防老剂TMPPD的迁移量增大,但总迁移量不大;3种防老剂中,防老剂TMPPD的耐迁移性能最佳,防老剂6PPD最差。
In this study,the migration of novel antioxidant TMPPD in the vulcanized NR was investigated by using high performance liquid chromatography and compared with antioxidant 6PPD and IPPD. The results showed that,with prolonged migration time,antioxidant TMPPD migration increased, but the total amount was little. Among the three kinds of antioxidant,antioxidant TMPPD showed the best migration resistance while antioxidant 6PPD had the worst.
