无机硅补强剂S20在高性能轮胎胎面胶中的应用

Application of Inorganic Silicon Reinforcing Agent S20 in High Performance Tire Tread

研究无机硅补强剂S20对高性能绿色轮胎胎面胶性能的影响。结果表明:与未添加填料分散剂的胶料相比,加入无机硅补强剂S20的胶料的门尼粘度显著降低,胶料流动性和填料分散性提高,加工性能改善,硫化胶的拉断伸长率增大,滚动阻力减小,抗湿滑性能和动态力学性能改善;与添加填料分散剂的胶料相比,加入无机硅补强剂S20胶料的加工性能明显改善,其他性能相差不大。

The effect of inorganic reinforcing agent S20 on the properties of green tire tread was investigated. The results showed that when filler dispersing aid was not used, the Mooney viscosity of the compound with S20 was lower, the fluidity of the compound, filler dispersion and processability were improved, elongation at break of the vulcanizates increased, rolling resistance decreased, and wet skid resistance and dynamic mechanical properties were improved. When filler dispersing aid was used, the processability of the compound with S20 was significantly improved, and other properties were similar.
