中文摘要: |
考察氯化顺丁橡胶(CBR)用量对其与CR,NBR或CPE并用胶的物理性能、耐老化性能和阻燃性能的影响。结果表明,随CBR用量的增大,CBR/CR和CBR/NBR的拉伸强度和拉断伸长率均下降,CBR/CPE的这两项性能均提高;老化或浸油后,3种并用胶的拉伸性能均随CBR用量的增大而下降;随CBR用量的增大,CBR/NBR的阻燃性能改善,CBR/CR和CBR/CPE的阻燃性能下降。 |
英文摘要: |
The influence of chlorobutadiene rubber(CBR) proportion on the physical properties,aging properties and flame retardance of CBR/CR,NBR or CPE blends was investigated.The results showed that the tensile strength and elongation at break of CBR/CR and CBR/NBR blends decreased,and those of CBR/CPE increased as the CBR proportion increased;the tensile strength of all three aged or oil-dipped blends decreased as CBR proportion increased,and the flame retardance of CBR/NBR blend improved,and that of CBR/CR and CBR/CPE blends decreased as the proportion of CBR increased. |
