摘要:在中试装置上合成相对分子质量分布较宽的充油S-SBR,考察不同环烷油和芳烃油填充量的充油S-SBR的流变性能和混炼行为。结果表明,增大油的填充量能提高充油SSBR的流动性能,充芳烃油S-SBR相对于充环烷油的S-SBR对温度更敏感,宽相对分子质量分布的充环烷油S-SBR的混炼性能优于S-SBR1204及ESBR1778,宽相对分子质量分布的充芳烃油S-SBR的混炼性能优于SSBR1204,Solprene 380和ESBR1712。

Abstract:The various oilextended S-SBRs(OESSBR) with broader molecular weight distribution were synthesized on a pilot plant and the rheological properties and mixing behaviour of S-SBRs extended with different contents of naphthenic oil or aromatic oil were investigated.The results showed that the flowability of OESSBR improved by increassing the content of oil;the S-SBR extended with aromatic oil was more sensitive to the temperature than that extended with naphthenic oil;the mixing behaviour of naphthenic oilextended SSBR with broader MW was superior to those of SSBR1204 or ESBR1778;and the mixing behaviour of aromatic oilextended S-SBR was superior to those of SSBR1204,Solprene 380 and ESBR1712.

摘要:
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25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。

Abstract:
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,t90 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.
