The invention relates to a device for producing a silicone and/or silane emulsion consisting of an active component containing silicone and/or silane, and an aqueous phase. Said device comprises a first mixing station for the emulsion components which are delivered by pumps (P],P2,P3) from reservoirs (VA, VB, VC), and is characterised in that said first mixing station has a mixing device (Ml) wherein nozzles (2,4) mix a jet of the active agent (1) with the aqueous phase (3) to produce a preliminary emulsion. The invention also relates to a method for producing fine-particle, stable silicone emulsions, especially for producing oil-in-water emulsions containing as little emulsifier as possible, and to emulsions produced according to said method.
L'invention concerne un dispositif permettant de préparer une émulsion à base de silicone et/ou de silane, comprenant un principe actif contenant du silicone et/ou du silane et une phase aqueuse. Il est prévu un poste de mélange destiné aux constituants de l'émulsion acheminés depuis des réservoirs (VA, VB, VC) par l'intermédiaire de pompes (P1, P2, P3). Ce dispositif se caractérise en ce que le premier poste de mélange présente un dispositif de mélange (M1) dans lequel des buses (2, 4) mélangent un principe actif en jet (1) avec la phase aqueuse (3) pour former une pré-émulsion. L'invention concerne en outre un procédé de préparation d'émulsions à base de silicone, stables et à fines particules, s'utilisant notamment pour préparer des émulsions huile dans l'eau avec le moins d'émulsifiant possible, ainsi que des émulsions pouvant être obtenues d'après ce procédé.
