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。
探討甜菜堿（三甲銨乙內酯，天然橡膠非膠組分）對聚異戊二烯橡膠（IR）硫化特性、彊伸性能和熱穩定性能的影響。結果錶明：與未加甜菜堿的IR相比，添加甜菜堿的IR硫化速度顯著提高，交聯密度增大，彊伸性能改善，熱穩定性能略有提高；噹甜菜堿用量為0.5份時，IR的綜閤性能最佳。

In this study, the inlfuence 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 signiifcantly, the crosslink density increased, tensile properties were improved and the thermal stability was slightly improved. The recommended addition level of betaine was 0.5 phr.
