Title
Paraffin/Wasser-Emulsion als Kaeltetraeger und Speichermedium sowie Verfahren zu deren Herstellung
Other Title
Emulsion, useful as coolant or storage medium for thermal energy, comprises an inner phase dispersed in a continuous phase, where inner phase contains a surfactant and a nucleating agent and continuous phase contains a thixotropic agent
Abstract
(A1) Die Erfindung bezieht sich auf eine Emulsion, die mindestens eine in mindestens einer kontinuierlichen Phase dispergierte innere Phase enthaelt, wobei die innere Phase mindestens ein Tensid sowie mindestens einen Keimbildner und die kontinuierliche Phase mindestens ein Thixotropierungsmittel enthaelt.

EP 2127737 A2 UPAB: 20091216 NOVELTY - Emulsion comprises at least an inner phase dispersed in at least a continuous phase, where the inner phase contains at least a surfactant and at least a nucleating agent and the continuous phase contains at least a thixotropic agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for producing the emulsion, comprising dispersing an inner phase in at least a continuous phase, where at least a surfactant and at least a nucleating agent are added to the inner phase and at least a thixotropic agent is added to the continuous phase, before dispersing. USE - The emulsion is useful as coolant and/or heat transfer medium and/or storage medium for thermal energy (claimed). ADVANTAGE - The emulsion shows a negligible tendency to coalesce. The temperature range of the phase change takes place in a closely limited temperature range. The emulsion shows improved storage stability. The reduction of cooling effect in the emulsion by nucleating agent is reduced.
