摘 要:针对高性能耐低温弹性体的原材料选择,选用不同苯乙烯含量的溶聚丁苯橡胶 (SSBR)与丁异戊共聚物(BIR)并用,研究了并用比对 SSBR/BIR 耐低温弹性体硫化特性、 Payne 效应、动态性能、低温性能和物理机械性能的影响,以此探讨高分子链中单体含量与低 温性能之间的关系。研究发现,当 SSBR5251H/SSBR1038/BIR 并用比为 20/40/40 时,胶料 的门尼黏度达到 61,填料的分散性差,填料网络作用强,硫化胶的损耗因子峰值最低。当 SSBR5251H/SSBR1038/BIR 并 用 比 为 0/50/50 时 ,硫 化 胶 的 玻 璃 化 转 变 温 度(Tg)最 低 , SSBR5251H/SSBR1038/BIR 并用比为 0/50/50 时硫化胶的压缩耐寒系数大,耐低温性、力学 性能和耐磨性表现优异。溶聚丁苯橡胶中的结合苯乙烯含量和 BIR 的并用量都对并用胶的 耐低温性有明显影响。

Abstract:The purpose of this study was to explore the relationship between monomer content in SSBR chains and low temperature performance of SSBR/BIR. SSBR/BIR low temperature elastomers were prepared with solution polymerized butadiene rubber (SSBR) with different styrene contents and BIR. The influence of blending ratio on the vulcanization characteristics, Payne effect, dynamic performance, low temperature performance and mechanical properties of SSBR/BIR was studied. It was found that when the blending ratio of SSBR5251H/ SSBR1038/BIR was 20/40/40, the Mooney viscosity of the compound reached 61. The dispersion of the filler was poor which formed a strong filler-filler network in the compound, and the peak loss factor of vulcanized rubber was the lowest. When the blending ratio of SSBR5251H/SSBR1038/BIR was 0/50/50, the glass transition temperature of vulcanized rubber was the lowest. Excellent low-temperature performance,mechanical properties and abrasion resistance were exhibited in vulcanizates. The low temperature performance of SSBR/ BIR elastomers was impacted significantly by the styrene content of SSBR and the combined content of BIR.
Key words:glass transition temperature; low-temperature property; blending ratio; lowtemperature elastomer
