    Effect of Titanate Coupling Agent Content on Performance of Magnetorheological Fluid

      Graphical Abstract
      • Abstract
    • A novel silicon-oil-based magnetorheological fluid (MRF) was prepared using titanate coupling agent with different contents as stabilizer and carboxyl iron powder as the magnetic particles. The effects of different volume fractions titanate coupling agents on sedimentation stability and shear properties of the MRF were compared. The results show that with the increase of the titanate coupling agent content the sedimentation stability of the MRF decreased. The MRF added 2vol% titanate coupling agent had the best sedimentation stability, while added 4vol% titanate coupling agent had a shear strength of 20 kPa when the magnetic field intensity was 400 mT. The quantitative relationship between shear strength and magnetic field intensity as well as the content of titanate was obtained when the volume fraction of carboxyl iron powder in MRF was 35vol%.
