Title:
MAGNETORHEOLOGICAL FLUID, METHOD FOR MANUFACTURING MAGNETORHEOLOGICAL FLUID, AND MAGNETORHEOLOGICAL FLUID DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/054622
Kind Code:
A1
Abstract:
Provided is a magnetorheological fluid containing magnetic particles, a carrier fluid, and an organic molybdenum compound, the magnetic particle content being 35–50 vol% (inclusive) with respect to the volume of the magnetorheological fluid, the viscosity of the carrier fluid measured by an electromagnetic rotary viscometer at a measurement temperature of 25°C being 10 mPa·s (millipascal seconds) or more, and the shear viscosity of the magnetorheological fluid measured at a shear rate of 1000 s−1 at a measurement temperature of 25°C being 500 mPa·s or less. Also provided are a magnetorheological fluid device including said magnetorheological fluid, and a method for manufacturing said magnetorheological fluid. The method for manufacturing said magnetorheological fluid includes resonant acoustic mixing of a mixture containing said magnetic particles, carrier fluid, and organic molybdenum compound.
