【摘要】 探讨抗硫化返原剂的作用机理,通过研究5种抗硫化返原剂对轮胎基部胶物理性能、tR97(胶料硫化转矩达到MH后再下降至97%MH所对应的时间)、硫化活化能和硫化返原降解活化能的影响,考察胶料抗硫化返原性能评价方法。结果表明:胶料过硫化后单项物理性能变化不能表征抗硫化返原性能;对于同类配方和相同生产工艺的胶料,tR97越长,抗硫化返原性能越好;tR97、硫化活化能和硫化返原降解活化能结合,可以评价胶料的抗硫化返原性能。更多还原

【Abstract】 In this study, the mechanism of anti-reversion agents was discussed. The influence of five antireversion agents on the physical properties, curing activation energy and reversion activation energy of the tire base eversion agents on the physical properties, curing activation energy and reversion activation energy of the tire base compound were experimentally investigated, and the evaluation methods of anti-reversion agents were discussed. It was found that the anti-reversion properties of the compound could not be assessed by the change of a single physical property after curing. For the compounds having similar recipe and production process, when the tR97(the time for the torque decreased from when it reached time for the torque decreased from when it reached MH to 97% of MH) was higher, the anti-reversion property was better. It was then recommended to use tR97, curing activation energy, and reversion activation energy together to evaluate the properties of anti-reversion properties.evaluate the properties of anti-reversion properties.更多还原
