Title:
ELECTROVISCOUS LIQUID
Document Type and Number:
Japanese Patent JPH02150494
Kind Code:
A
Abstract:
PURPOSE: To obtain an electroviscous liquid without need of drying, exhibiting extremely quick response to applying and removing of electric voltage, large electroviscous effect and small electric power consumption by comprising respectively specific dispersion phase of crystallized zeolite and liquid phase of electric insulating oil.
CONSTITUTION: The aimed electroviscous liquid is composed of (A) 1-60% dispersion phase of crystallized zeolite expressed by the formula [M is H-ion or metallic cation (mixture) having average valence (n); x and y are integers of y/x=10-200] and having 0.05-10wt.% and 0.01-20μm average particle size and (B) 40-99-% liquid phase of electric insulating oil having 0.65-500cst viscosity at room temperature.
