新型增塑剂DINCH对丁腈橡胶性能的影响

摘要

The effect of new plasticizer DINCH on the properties of NBR compound was investigated and compared to several common plasticizers. The results showed that,in the peroxide and sulfur vulcanization systems, NBR vulcanizate with plasticizer DINCH had better tensile properties, lower compression set,and good oil resistance;the cold resistance of the vulcanizate with DINCH was between that with plasticizer DBPCor DOP) and plasticizer DBS(or DOS).%研究新型增塑剂DINCH对丁腈橡胶(NBR)性能的影响,并与几种常用增塑剂进行对比.结果表明,在过氧化物和硫黄硫化体系下,加入增塑剂DINCH的NBR硫化胶具有较好的强伸性能和较低的压缩永久变形,其耐寒性能介于增塑剂DBP或DOP和增塑剂DBS或DOS硫化胶之间,且耐油性能良好.
