| 摘 要： | 探讨甜菜碱(三甲铵乙内酯,天然橡胶非胶组分)对聚异戊二烯橡胶(IR)硫化特性、强伸性能和热稳定性能的影响。结果表明:与未加甜菜碱的IR相比,添加甜菜碱的IR硫化速度显著提高,交联密度增大,强伸性能改善,热稳定性能略有提高;当甜菜碱用量为0.5份时,IR的综合性能最佳。

| Abstract: | In this study, the influence of betaine （N,N,N-trimethylglycine, non-rubber component in natural rubber） on the curing characteristics, tensile properties and thermal stability of polyisoprene rubber （IR） was investigated. Compared with the IR compound without betaine, the curing rate of the compound with betaine IR increased significantly, the crosslink density increased, tensile properties were improved and the thermal stability was slightly improved. The recommended addition level ofbetaine was 0.5 phr |
