摘    要:研究了不同门尼粘度的反式-1,4-聚异戊二烯(TPI)与氯丁橡胶(CR)并用胶的性能,并对比了CR/TPI与CR硫化胶的性能。结果表明,CR中并用10份TPI可明显改善开炼机混炼时的粘辊性、胶料在硫化过程中产生气泡等缺陷;并用TPI后。硫化胶的物理机械性能、耐热老化性能和耐臭氧性能有所下降,但当TPI与CR门尼粘度相近时,硫化胶的耐屈挠疲劳性能可提高1倍左右。

关 键 词:反式-1  4-聚异戊二烯  氯丁橡胶  并用  耐屈挠性能

Abstract:The blend properties of chloroprene rubber(CR) and trans1,4-polyisoprene(TPI)with different mooney viscosity were studied,and the vulcanizate properties of CR/TPI and CR were compared.The results showed that the roll sticking property of CR was significantly improved,and did not produce bubble during the curing process by adding 10 phr TPI;Blended with TPI,the physical-mechanical properties,thermal aging resistance and ozone resistance of CR vulcanizate all dropped;The flex durability was increased by 1 time when the mooney viscosity of CR and TPI were equivalent.
Keywords:TPI  CR  blending  flex durability
