促进剂TBSI在全钢载重子午线轮胎中的应用

Application of TBSI accelerator in BTR tire

研究促进剂TBSI在全钢载重子午线轮胎上三角胶和胎体胶中的应用。在上三角胶配方中以促进剂TBSI等量替代促进剂NS ,胶料的焦烧时间延长 ,硫化速度减慢 ,抗硫化返原性能提高 ,硫化胶的强伸性能及撕裂性能较优。在胎体胶配方中以 1份促进剂TBSI替代 1 2 5份促进剂DZ ,胶料的焦烧时间延长 ,t90 缩短 ,硫化胶的拉断永久变形减小 ,H抽出力相当。

The application of TBSI accelerator in upper bead filler and carcass compounds of BTR tire was investigated.The results showed that the scorch time extended,the curing speed reduced,the anti-reversion improved,and the better tensile,elongation and tear properties were obtained using TBSI instead of TBBS by equal weight in the upper bead filler compound;and the scorch time extended,t_(90) reduced,the permanent tensile set decreased and the H pull-out changed little using 1 phr of TBSI instead of 1.25 phr of DCBS in the carcass compound.
