【Abstract】 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.更多还原
