| 摘 要： | 研究反式-1,4-丁二烯-异戊二烯共聚橡胶(TBIR)的结晶性能、加工性能以及NR/BR/TBIR并用胶在轿车轮胎胎侧胶中的应用。结果表明:相比反式-1,4-聚异戊二烯(TPI),TBIR的结晶性能微弱、玻璃化温度更低;相比天然橡胶(NR)和顺丁橡胶(BR),TBIR具有优异的加工性能;相比NR,BR和TPI,TBIR的耐老化性能优异;相比NR/BR和NR/BR/TPI并用胶,NR/BR/TBIR(并用比为45/35/20)并用胶的物理性能优异,生热降低,耐裂口扩展性能显著提高。TBIR作为一种新型合成橡胶材料可应用于高耐疲劳轿车轮胎。

| Abstract: | The crystalline behavior, processing performance of two different trans-1,4-poly(butadiene-co-isoprene) copolymer rubbers (TBIR) and properties of sidewall stock of PCR tire utilized with TBIR were studied. It was found that, compared with trans-1,4-polyisoprene (TPI), TBIR showed a weaker crystallization performance and a lower glass-transition temperature (Tg). Compared with nature rubber (NR) and cis-1,4-polybutadiene rubber (BR), TBIR presented improved processing properties. Compared with NR, BR and TPI, TBIR demonstrated excellent hot oxygen ageing resistance. Compared with NR/BR and NR/BR/TPI vulcanizates, NR/BR/TBIR(45/35/20) vulcanizates showed excellent physical and mechanical properties, lower heat built-up and outstanding crack-growth resistance. So TBIR was a novel synthesis rubber for high performance tire sidewall. |
