Abstract:
The fabrication of magnetorheological (MR) elastomers was studied by two vulcanization methods, including heat vulcanization (HV) and radiation vulcanization (RV), were em-ployed to fabricate MRE samples. The dynamical mechanical properties were characterized by using a dynamic mechanic analyzer. In particular, both the MR effect and its durability were investigated.The experimental results showed that RV samples have large magneto-induced modulus,large zero-field modulus,and good durability property of MR effect.To explain these results,cubic deformation and plasticizer migration were analyzed. Large magneto-induced modulus of RV sample results from cubic deformation during vulcaniza-tion process. And the plasticizer migration results in better durability of MR effect.

摘要:
介绍了两种制备磁流变弹性体的硫化方法即高温硫化和辐射硫化. 研究中采用动态力学分析仪(DMA)测量了样品的动态力学特性.特别是对样品的磁流变效应和耐久性进行了详细的测试. 实验结果表明,经过辐射硫化的样品具有更大的零场模量和磁致模量,以及更好的磁流变效应和耐久性. 为了解释这些结果,文章对样品的体积形变和增塑剂渗出都作了详细的分析. 在硫化过程中样品的体积保持稳定是辐射硫化样品具有大磁致模量的重要原因,而增塑剂渗透性小也是辐射硫化样品具有高磁流变效应和耐久性的重要因素.
