| 摘 要： | 采用橡胶加工分析仪RPA2000,对目前海南、云南、广东三大植胶垦区中拟大规模推广种植的7个不同新品系天然生胶的加工性能进行分析,指标包括胶料的稠度及流变指数、粘弹特性、应力松弛时间、耐老化性能等.结果表明,云研77-2和热垦7-33-97生胶加工性能好,利于混炼加工;云研77-2及云研77-4的塑性保持率较小,耐老化性能差;湛试93-114的塑性保持率最大,耐老化性能最优.

| Abstract: | The processabilities of raw natural rubbers from 7 new clones intending to widely plant in the rubber planting areas of Hainan, Yunnan and Guangdong were studied using a rubber process analyzer RPA2000. Processabilities indecies contained consistency coefficient and rheological index, viscoelastic characteristic, stress relaxation time and ageing resistance. The results showed that raw natural rubbers from clones of Yunyan 77-2 and Reken 7-33-97 had good processability and were easy to mix. Raw natural rubbers from Yunyan 77-2 and 77-4 were lower in plasticity retention index (PRI) and poorer in ageing-resistance, whereas raw natural rubber from clone of Zhanshi 93-114 possessed the highest PRI and the best aging resistance. |
