Abstract
(DE)
Die Erfindung betrifft eine neuartige Zusammensetzung eines Gießharzes und die Verwendung davon beim heißhärtenden Elektroverguss, wie er beispielsweise bei der Herstellung elektrotechnischer Bauteile wie Transformatoren, Isolatoren, Kondensatoren, Spulen und Baugruppen eingesetzt wird. Außerdem betrifft die Erfindung einen Formkörper, der aus dem Gießharz erhältlich ist, sowie die Verwendung eines derartigen Formkörpers. Durch die Erfindung wird erstmals ein Gießharz für den heißhärtenden Elektroverguss vorgestellt, bei dem auf Weichmacher und Flexibilisatoren verzichtet werden kann. Dies wird durch die Abmischung der Epoxidharzbasis mit cycloaliphatischen Epoxidharzen und die Zugabe hochdisperser Nanopartikel erreicht.
(EN)
The invention relates to a novel composition of a casting resin and the use thereof in hot-curing electro casting, as is used for example in the production of electrical components, such as transformers, insulators, capacitors, coils and assemblies. The invention additionally relates to a shaped article which is obtainable from the casting resin and to the use of a shaped article of this kind. By means of the invention, a casting resin with which it is possible to dispense with plasticisers and flexibilisers is provided for the first time for hot-curing electro casting. This is achieved by the mixing of the epoxy resin base with cycloaliphaticepoxy resins and the addition of highly dispersed nanoparticles.

L’invention concerne une nouvelle composition d’une résine de coulée et l’utilisation de celle-ci dans le scellement électrique thermodurcissable, tel qu’utilisé, par exemple, dans la fabrication de composants électriques tels que transformateurs, isolateurs, condensateurs, bobines et modules. L’invention concerne en outre un corps moulé, lequel peut être obtenu à partir de la résine de coulée, ainsi que l‘utilisation d’un tel corps moulé. La résine de coulée pour le scellement électrique thermodurcissable selon l’invention est la première permettant de renoncer à des plastifiants et des flexibilisateurs. Ceci est rendu possible par le mélange de la base de résine époxy avec des résines époxy cycloaliphatiques et l’ajout de nanoparticules hautement dispersées.
