Abstract:
Organopolysiloxane emulsions which are stable and of large particle size are produced in controllable fashion using a cylindrical mixer having multiple inlets and axially displaced rotor stator units.

Claim (Index 15):
A continuous process for production of emulsions which comprise polyorganosiloxanes (A), emulsifiers (B), water (C) and optionally further components (D), comprising:\n continuously feeding components (A) through (D) into a cylindrical mixer comprising two or more rotor-stator mixing elements providing axial flow therethrough, wherein the rotor and stator elements are each arranged with an axial offset, and the cylindrical mixer contains at least one feedpoint upstream from the mixing elements of the cylindrical mixer and at least one further feedpoint along the mixer between mixing elements, supplying the polyorganosiloxanes (A) via a feedpoint at the entry to the mixer, optionally in the form of a premix with a portion of one or more of emulsifiers (B), water (C), further components (D) and mixtures thereof, and supplying emulsifiers (B) and water (C), optionally portions of polyorganosiloxanes (A), and optionally further components (D), separately or as a premix at one or more feedpoints upstream from the mixing elements and/or at one or more feedpoints between the mixing elements, wherein the admixture of the total amounts of components (A) to (D) is in each case effected independently of one another via one feedpoint or across two or more feedpoints, where the central particle size D(50) of the emulsions is greater than 1 \u03bcm, and controlling the central particle size D(50) of the emulsions by splitting the proportions of components (A) to (D), which are imported at the further feedpoints between the mixing elements along the mixer, and continuously withdrawing a product emulsion from the cylindrical mixer, where the central particle size relates to the D(50) value of the volume distribution as measured by the principle of Fraunhofer diffraction corresponding to ISO 13320 and the parameters for measurement assume a spherical model having a refractive index of 1.33 for the continuous phase, of 1.39 for the disperse phase, and an absorption of 0.01.
