| 中文摘要: |
| 研究了两种牌号反式-1,4-丁二烯-异戊二烯共聚橡胶(TBIR)的生胶结晶性能、加工性能以及NR/BR/TBIR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结晶性能微弱、玻璃化转变温度(Tg)更低；相比天然橡胶(NR)和顺丁橡胶(BR),TBIR具有更加优异的加工性能；相比NR、BR和TPI,TBIR生胶耐老化性能优异。相比NR/BR和NR/BR/TPI并用胎侧胶,TBIR取代20份BR后,NR/BR/TBIR(45/35/20)并用硫化胶物理机械性能优异,生热降低,耐裂口扩展性能显著提高。综合可知,TBIR作为一种新型的合成橡胶材料,可应用于高抗疲劳性轿车轮胎。 |
| 英文摘要: |
| 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. |
