摘要
研究了硫黄、促进剂、改性胶粉用量对胶粉/SBR共混胶料性能的影响。结果表明;改性胶粉用量在10-35份的范围内.对共混胶料的静态力学性能影响不大:在10-22份的范围内对动态压缩疲劳生热影响不大.适当调整基质胶中硫黄、促进剂的用量.有利于降低胶料的动态压缩疲劳生热。扫描电子能谱微区分析的研究表明:由于硫黄的迁移形成了具有特殊结构的界面过渡层.该过渡层是降低动态压缩疲劳生热的关键。
The influence of the levels of sulfur,accelerator and modified ground rubber/SBR blend was investigated. The results showed that the static properties of the blend was not influenced significantly when 10-35 phr modified ground rubber was used; the dynamic compression fatigue heat build-up was not influenced significantly when 10-22 phr ground rubber was used; and it was benificial to the dynamic compression fatigue heat build-up to adjust the levels of sulfur and accelerator in the rubber matrix appropriately. The domain analysis with SEES showed that the migration of sulfur resulted in a transition layer with a special structure at the boundary, which was the key factor to decrease the dynamic compression fatigue heat build-up.
