| 摘 要： | 在丁腈橡胶(NBR)中添加酚醛(PR)和受阻酚AO60,制备NBR/PR/AO60共混橡胶。采用DSC,FTIR,扫描电子显微镜和黏弹谱仪等方法表征NBR/PR/AO60共混橡胶的结构,并详细研究其阻尼机理。结果表明:在共混橡胶结构中,除NBR的硫化交联网络外,还包含NBR/AO60的超分子氢键网络、NBR/PR的络合作用、AO60与PR分子间作用、AO60分子聚集体(富相区)以及在AO60相中的NBR分子等多种微观作用形式。多种的分子作用形式,造成了硫化胶的分子间内摩擦增大,提高了阻尼性能。但随着贮存时间的延长,硫化胶的tanδ-温度曲线由双峰特征变为三峰特征,AO60分子逐渐聚集、结晶,形成大的结晶聚集体,造成硫化橡胶阻尼性能的不稳定。

| Abstract: | The phenolic resin(PR) and tetrakis(methylene-3-(3-5-ditert2butyl242hydroxy phenyl) propionyloxy) methane(AO60) were added into the acrylonitrile-butadiene rubber(NBR) to prepare the vulcanized NBR/PR/ hindered phenol rubbers.The structures of the vulcanized rubbers were characterized by DSC,FTIR,DMTA and SEM.And their damping and mechanical mechanism were investigated in detail.The results show that the microscopic structures of vulcanized rubber include the networks of intermolecular hydrogen bonds betwee... |
