Title:
磁気粘性流体
Document Type and Number:
Japanese Patent JP7176916
Kind Code:
B2
Abstract:
To provide magnetic viscous fluid capable of achieving excellent dispersion stability and re-dispersibility of magnetic particles, high exciting average torque value and short torque recovery time.SOLUTION: The magnetic viscous fluid containing magnetic particles, disperse medium, fatty amide, dispersant and dispersion assistant acquires dispersion stability and re-dispersibility of magnetic particles. The magnetic viscous fluid has high exciting average torque value and short torque recovery time; therefore, it can be suitably used to control a frictional force working between objects in various types of apparatuses such as a brake, a clutch, a vibration isolator and a damper of a vibration control device.SELECTED DRAWING: None
