摘要
研究新型防老剂RT-1对天然橡胶(NR)性能的影响。结果表明:加入防老剂RT-1,NR胶料的ML增大,MH减小,t90和ts1延长,老化后NR硫化胶的拉伸性能较好,热氧化活化能增大;防老剂RT-1对NR硫化胶热氧老化的防护效果优于防老剂BHT和4010NA。
The effect of new antioxidant RT-1 on the properties of NR compound was investigated. The results showed that,by adding antioxidant RT-1, the ML of the NR compound increased, the M. decreased, the t90 and ts1 were extended,the tensile properties of the NR vulcanizates after aging were better, and the activation energy of thermal oxidation increased. It was indicated that the protective effect of antioxidant RT-1 in NR vulcanizate against thermal oxygen aging was superior to that of antioxidant BHT and 4010NA.
