摘　　要：研究液体抗氧剂(简称抗氧剂)优配B7081L在钕系顺丁橡胶(NdBR)中的应用,并与抗氧剂B7802,1520和B7720进行对比。结果表明,与采用其他3种抗氧剂的NdBR胶料相比,采用抗氧剂优配B7081L的NdBR胶料表现出良好的门尼粘度稳定性和抗黄变性能,热氧老化后的凝胶含量没有明显变化,氧化诱导时间较长。The application of liquid antioxidant(antioxidant for short)B7081l in neodymium butadiene rubber(NdBR)was studied,and compared with antioxidant B7802,1520 and B7720.The results showed that,compared with the compound of NdBR with three other antioxidants,the compound of NdBR with antioxidant B7081L exhibited good Mooney viscosity stability and yellowing resistance,the gel content after thermal oxidative aging did not change significantly,and the oxidation induction time was longer.
