新型橡胶代用材料PVCR的应用试验

考察了易与橡胶共混的改性聚氯乙烯树脂(PVCR)在通用橡胶(NR，BR 和SBR)和胶管、胶带胶料中的应用情况。结果表明，PVCR可在常温下以常规混炼工艺与通用橡胶较好地混合；在纯胶配方中以PVCR等量替代10份NR、20份BR或15份SBR对胶料性能影响不大；在普通胶管、胶带胶料中也可以以10～20份的用量对其中的通用橡胶进行等量替代。;The application of a modified PVC (PVCR)partly instead of NR，BR or SBR in rubber hose and belt production w as investigated .The results showed that PVCR could be well blended with the general rubbers using common mixing technology at the normal temperature；the physical properties of rubber compound were affected little by using 10 and 20 phr of PVCR instead of equal parts of BR or 15 phr of PVCR instead of equal parts of SBR in whole rubber fo rmula；and 10 ～ 20 phr of PVCR could be used instead of general rubbers in conventional rubber hose and belt compounds
