  Title: Design and characterization of functionalized S-SBR for eco-tire with low rolling resistance and high wear resistance.

  题材:合同于低滚阻和高耐磨ECO轮胎的成效化SSBR的计划和特色

  Abstract:摘要

  Rolling resistance of tires has attracted much attention in the eco-tire industry because it strongly relates the fuel efficiency. Key technology for the reduction of the rolling resistance of the tire is to improve dispersion of fillers, e.g. silica, in the tread compounds. In this regards, some solution-styrene butadiene rubbers (S-SBR) with functional moiety at chain end have developed to achieve good interaction with silica fillers. Additionally, in recent, high wear resistance of the tire has also been desired even in the eco-tire treads. To improve these properties, it is strongly required further modification of the S-SBR.

  轮胎滚动阻力在ECO轮胎行业里引起了很大的关怀,因为他与燃油效率息息相关。降低滚动阻力的主要技术是改进填料分散,例如,轮胎胎面胶里之白炭黑。在这方面,有的头基功能团改性的溶液聚合丁苯橡胶能和白炭黑填料达到很好的组成。此外,eco轮胎胎面也急需轮胎的高耐磨性。为了提高这些性能,明确要求更好改性的S-SBR. 

  Asahi-kasei’s S-SBR provides significant improvement of the rolling resistance as well as the wear resistance of the tire tread compounds due to our unique functionalization and high molecular weight technologies. To improve rolling resistance property, our development of S-SBR for the eco-tire tread compounds has been focused on the functionalization of the both chain ends.

  The technology of the installing functional moieties which have a good interaction with silica into the both chain ends of the S-SBR enabled to achieve quite low hysteresis loss property due to an improvement of silica dispersion as well as a fixation of the free chain end on the surface of the silica in the compounds. The fixation of the free chain reduced an energy loss because it prevented the chain to move during tire rolling. To enhance wear resistance property, a polymerization technology to produce S-SBR which has a high molecular weight has been developed in our company. It has been well known that the molecular weight of S-SBR strongly relates wear resistance because breaking strength is enhanced by the increasing of the molecular weight.

  However, there were serious troubles in the manufacturing process to produce high molecular weight polymers which showed quite high viscosity. Note that we achieved to produce a quite high molecular weight S-SBR by an installation of a branching structure in the polymer chain because the structure enabled to decrease the polymer viscosity.

  旭化成S-SBR异常之成效化和高分子量技术对于轮胎的滚动阻力和胎面胶耐磨性有明显的加强。为了改善滚动阻力的性质,咱们对eco轮胎胎面胶的S-SBR的科研重点放在了双端基官能团改性。SSBR双端基官能团引进技术可以改善白炭黑的分散性,同时把聚合物自由端固定在胶里之白炭黑表面,因此拥有很低的落后性能. 自由链端的稳定降低了能量损失,是因为他在轮胎滚动期间防止了链的运动。为了加强耐磨性能,咱们企业支付了生育高分子量S-SBR的集聚技术。显而易见SSBR总量与耐磨性密切相关,因为随着总量的增长,扯断强度也随之增强。可是,在生养很高粘度的高分子量聚合物的生产工艺里会生活很要紧的题目。注意到这个后,咱们通过在聚合物链上支链化技术,制造超高分子量的S-SBR,因为支链化结构能降低聚合物粘度。

  We will present our S-SBR grades and development strategy, the latest generation of functionalization technology, and the mechanism of such performance improvements.

  咱们将展示不同之S-SBR牌号和付出策略,新一代的成效化技术,以及改善这些性能的公有制。
