高压海水介质对丁腈橡胶性能的影响

摘要

The effect of high pressure seawater on the properties of nitrile rubber (NBR)was studied.The results showed that,when the immersion time was extended,the mass change ratio of NBR vulcanizate increased,and the tensile strength and tensile elongation at break decreased.Compression temperature rise and compression set tended to decrease as the immersion time was extended,and the compression temperature rise and compression set were smaller when the aging temperature was higher.The damping properties were decreased with the increase of immersion time and aging temperature.%研究高压海水介质对丁腈橡胶(NBR)各项性能的影响.结果表明:随着浸泡时间的延长,NBR硫化胶的质量变化率呈增大趋势;拉伸强度和拉断伸长率呈减小趋势;压缩疲劳温升和压缩永久变形减小,且老化温度越高,压缩疲劳温升和压缩永久变形越小;阻尼性能降低,且老化温度越高,阻尼性能越差.
