中文摘要:
      研究防老剂L60（主要成分源于木质素）在天然橡胶（NR）中的应用，并与防老剂264、防老剂2246、防老剂445和防老剂4020进行对比。结果表明：防老剂L60会降低胶料的硫化速度；防老剂L60硫化胶的耐热空气老化性能较好，耐臭氧老化性能与防老剂264硫化胶相当；防老剂L60对NR硫化胶的热分解温度影响较小。
英文摘要:
      The application of antioxidant L60（its main component was derived from lignin） in natural rubber （NR） was studied and compared with antioxidant 264，antioxidant 2246，antioxidant 445 and antioxidant 4020. The results showed that，antioxidant L60 could reduce the curing speed of the compound. The hot air aging resistance of the vulcanizate with antioxidant L60 was better，and the ozone aging resistance was comparable to that of the vulcanizate with antioxidant 264. Moreover，antioxidant L60 had little effect on the thermal decomposition temperature of NR vulcanizate
