摘　　要：研究普通硫化(CV)体系、半有效硫化(SEV)体系、有效硫化(EV)体系对农业轮胎用乳聚丁苯橡胶(ESBR)/轮胎再生胶(TRR)共混物性能的影响。研究表明:采用CV体系的胶料的门尼粘度低,流动性好;采用EV和SEV体系的胶料的门尼粘度稍高;采用CV体系的硫化胶的定伸应力和拉伸强度最高,耐磨性能和耐屈挠疲劳性能最好,但耐老化性能差,压缩永久变形大;采用EV体系的硫化胶的耐老化性能最好,压缩生热低,压缩永久变形小,耐屈挠疲劳性能较差;采用SEV体系的硫化胶的综合性能较好;采用促进剂TBSI的硫化胶的撕裂强度高,耐老化性能较好,压缩生热低,压缩永久变形小;对于农业轮胎,采用含促进剂TBSI的SEV体系的ESBR/TRR共混物较为合适。The effects of common vulcanization(CV)system,semi effective vulcanization(SEV)system and effective vulcanization(EV)system on the properties of emulsion-polymerized styrene butadiene rubber(ESBR)/reclaimed tire rubber(TRR)blends for agricultural tires were studied.The results showed that,the compound with CV system had low Mooney viscosity and good fluidity,and the compounds with EV and SEV system had higher Mooney viscosity.The vulcanizate with CV system had the highest modulus and tensile strength,the best wear resistance and flexural fatigue resistance,but had poor aging resistance and large compression set.The vulcanizate with EV system had the best aging resistance,low compression heat build-up and small compression set,but poor flexural fatigue resistance.The overall properties of the vulcanizate with SEV system were good.The vulcanizate with accelerator TBSI had high tear strength,good aging resistance,small compression heat build-up and compression set.For agricultural tires,the ESBR/TRR blend with SEV system containing accelerator TBSI was more suitable.
