摘要
用二水合氯化亚锡(SnCl2.2H2O)作氢化丁腈橡胶(HNBR)的硫化剂,研究了硫化温度、SnCl2.2H2O用量对混炼胶硫化特性以及硫化胶力学性能的影响,并采用傅立叶变换红外光谱(FTIR)对其化学结构进行了表征。结果表明:SnCl2.2H2O可以使HNBR产生硫化,硫化胶具有良好的力学性能,其交联结构完全不同于传统的有机过氧化物硫化橡胶。
SnCl2· 2H2O and HNBR were used as the curing agent and matrix in this study, respectively. The effect of curing temperature and the content of SnCl2 · 2H2O on the curing properties of the composites and the mechanical properties of the vulcanizates were studied. The chemical structure was characterized by FTIR. According to the testing results, HNBR could be cured by SnCl2·2H2O, and the cross-link structure of the vulcanizates was different from the traditional one cured by organic peroxides. The vulcanizates had good mechanical properties.
