摘要
通过对比SBR1723与SBR1712生胶与胶料性能,研究环保芳烃油（TDAE）对充油SBR性能及其在轿车子午线轮胎胎面胶中应用性能的影响。结果表明,由于填充油品不同,SBR1723玻璃化转变温度比SBR1712低2-3℃,其混炼胶加工性能稍差,硫化胶拉断伸长率下降,滚动阻力和生热降低,耐磨性较好,抗湿滑性能有所下降。在轿车子午线轮胎胎面胶中应用时,随着补强剂作用的加强,填充油品的影响变小,适当提高白炭黑用量可进一步降低滚动阻力和改善抗湿滑性能。
The influence of enviroment-friendly aromatic oil （TDAE） on properties of oil-extended SBR （OESBR） and those of OESBR-based tread compound for PCR tire was investigated by comparing the properties of green SBR1723 and its compound to those of SBR1712. The results showed that because of different types of extending oils,SBR1723 had 2-3℃ lower Tg ,somewhat poorer processibility of mix,and lower enlongation at break, rolling resistance and heat build-up, better abrasion resistance and somewhat poorer wet traction of vulcanizate when compared to SBR1712. The influence of extending oil type in tread compound of PCR tire decreased as the reinforcement increased, and the rolling resistance and wet traction could be improved further by increasing the addition level of silica properly.
