ABSTRACT:
Method and apparatus for preparing uniform highly dispersed emulsions by using a low drive power and without pressurization, making possible continuous mass production of uniform organopolysiloxane emulsions. An organopolysiloxane, water and a emulsifying agent, are continuously fed across a first-stage shearing and stirring mechanism and a second-stage shearing and stirring mechanism. The first-stage mechanism is a stator and turbine-type rotor whose blades are slanted obliquely from the radial direction when viewed from the axial direction. The second-stage mechanism is a stator and turbine-type rotor whose blades describe spiral curves with respect to the axial direction. The two mechanisms are arranged serially and separated from one another by a relaxation zone. Emulsification is carried out in the first-stage mechanism by an intake and shearing action at a shear rate of at least 100/second, and in the second-stage mechanism by a phase reversal rotating effect and shearing action at a shear rate of at least 100/second.
