ELECTRORHEOLOGICAL FLUIDS BASED ON SYNTHETIC SHEET SILICATES

摘要

Electrorheological fluids based on synthetic sheet silicates Electrorheological fluids have been developed which essentially comprise an aluminum-free metal silicate hydrate which has a sheet structure, a dispersant and an inert aprotic dispersion medium. The metal silicate hydrate preferably is of the kenyaite, magadiite and/or kanemite type. The dispersion medium is preferably a silicone oil having a viscosity range of from 0.5 to 1,000 mPas and/or a mineral oil or a paraffin oil having a viscosity range of from 0.1 to 1,000 mPas. The metal silicate hydrate is added to the electrorheological fluid in a concentration of from 1 to 50% by weight.
