低温增塑剂对NR/BR阻尼材料性能的影响
|
摘要
研究了癸二酸二辛酯/己二酸二辛酯(DOS/DOA)并用比对天然橡胶(NR)/顺丁橡胶(BR)阻尼材料的硫化特性、物理机械性能、低温性能、阻尼性能及动态机械性能的影响。结果表明,随着DOA用量增加、DOS用量减少,混炼胶最大扭矩、最小扭矩减小,焦晓时间、正硫化时间变化不大;DOS/DOA并用比对硫化胶物理机械性能及阻尼性能影响不大;DOS/DOA并用可以降低硫化胶的玻璃化转变温度,且当DOS/DOA质量比为10/10时,温度相关性最佳,综合性能最佳。
The effects of DOS/DOA on vulcanization properties,physical mechanical properties,low temperature properties,damping properties and dynamic properties of rubber damping materials were studied.The results showed that with the increase of DOA usage and the decrease of DOS usage,M_H,M_L of mixing glue decreased,and t_(10),t_(90) changed little;DOS/DOA ratio has little effect on physical mechanical properties and damping properties of Vulcanized rubber;DOS/DOA can reduce the glass transition temperature of the vulcanizates.The temperature dependence and the comprehensive performance of the vulcanizates are the best when DOS/DOA dosage ratio is 10/10.
