采用热空气老化箱常规法结合热重分析(TG)法、差示扫描量热(DSC)法及橡胶加工分析(RPA)法研究了2种不同品系NR硫化胶的耐老化性能.实验结果表明:品系PB68硫化胶的耐老化性能比品系RRIM600硫化胶的好.
The aging resistances of natural rubber (NR) vulcanizates from different clones of rubber trees are investigated by the conventional method of hot-air aging combined with thermogravimetry (TG), differential scanning calorimetry (DSC) and rubber processing analyzer (RPA). The results show that the aging-resistance of NR vulcanizate from clone PB68 is better than that of clone RRIM600.
