聚硅氧烷基磁流变粘弹性流体制备方法与力学性能测试
Preparation and Mechanical Properties Test for Polysiloxane Based Magneto-rheological Viscoelastic Fluid (MRVF)
以六甲基二硅氧烷和聚二苯基硅氧烷制得的线性聚硅氧烷作为磁流变材料的载体，加入添加剂，采用球磨分散方法，研制出了四种不同组分磁流变粘弹性流体(MRVF)样品。采用奥地利安东帕高级旋转流变仪（MCR-301）对上述样品进行了力学性能测试。实验表明：在剪切率为200s-1，磁感应强度为0~0.9T条件下，剪切应力的调节范围为5~120kPa；根据剪切应力与剪切率关系曲线，磁流变粘弹性流体的剪切稀化明显，剪切屈服应力显著；在剪切率为200s-1，在磁感应强度为0.1T~0.9T，第一法向应力差的变化范围为20kPa~140kPa。
new MR material, named as Magneto-rheological viscoelastic fluid (MRVF), is put forward. The carrier of MRVF is based on the chemical products of hexamethyldisiloxane and polyborodiphenylsiloxane. By means of ball milling method and special additives, four samples are developed. The rotary rheometer, Austrian Anton Par MCR-301, is used to test the mechanical properties of the samples. The experimental results show that the shear stress varies from 5kPa to 120kPa with the shear rate of 200s-1 and magnetic induction intensity of 0~0.9T. According to the curves of shear stress versus shear rate ,the shear thining and yield-effect of MRVF is significant.The first normal-stress difference of MRVF varies from 20kPa to 140kPa with the shear rate of 200s-1 and magnetic induction intensity of 0.1~0.9T.?????
