中文摘要:
      研究偶联剂Si747和Si69对白炭黑/炭黑并用体系补强天然橡胶（NR）性能的影响。结果表明：与偶联剂Si69混炼胶相比，偶联剂Si747混炼胶的硫化速率较大；随着一段密炼排胶温度升高，两种偶联剂混炼胶小应变储能模量（G′1）与大应变储能模量（G′2）的差值（G′1－G′2）呈下降趋势；排胶温度适当提高有利于改善偶联剂Si747硫化胶的物理性能；偶联剂Si69硫化胶的滚动阻力较小，偶联剂Si747硫化胶的抗湿滑性较好。
英文摘要:
      In this study，the influence of silane coupling agents Si747 and Si69，on the properties of silica/carbon black reinforced NR compound was investigated.It was found that comparing with the Si69 modified compound，the curing speed of the compound with Si747 was higher.As the discharging temperature of first mixing stage increased，the difference between the storage modulus at small strain （G′1） and the storage modulus at large strain （G′2），G′1-G′2 decreased. The physical properties of the vulcanizates with Si747 were improved with a proper increase of the discharging temperature. It was also found that the rolling resistance of the vulcanizates with Si69 was lower，and the wet skid resistance of the vulcanizates with Si747 was better.
