Title (EN) POTTING COMPOUND, INSULATING MATERIAL, AND USE THEREOF

Abstract:
(EN) The invention relates to a novel potting compound, in particular a potting compound which can be used to produce an insulating material by means of an anhydride-free hardening process. The invention further relates to the use of the insulating material in switchgears, transformers, cast resin transformers, and/or in the corresponding semi-finished product. For this purpose, the invention first discloses a potting compound with a hardening component that is used to facilitate an anionically-initiated homopolymerization of sterically hindered epoxide resins, which has been considered impossible according to the prior art until now. For this purpose, superbases are used with a pKB value of more than 23.
(FR) L'invention concerne une nouvelle masse de scellement, en particulier une masse de scellement qui peut être utilisée dans la fabrication d'un matériau isolant par durcissement d'une résine sans anhydride. L'invention concerne en outre l'utilisation du matériau isolant dans des appareillages électriques, des transformateurs, des transformateurs secs enrobés de résine et/ou qui peut être utilisé dans le produit semi-fini correspondant. En outre, l'invention concerne premièrement une masse de scellement contenant un composant durcisseur qui permet une homopolymérisation anionique de résines époxydes stériquement encombrées, ce qui, jusqu'à présent, n'était pas faisable selon l'état de la technique. De plus, on utilise de ce que l'on appelle des superbases ayant une valeur pKb supérieure à 23.
(DE) Die Erfindung betrifft eine neuartige Vergussmasse, insbesondere eine, die zur Herstellung eines Isolationswerkstoffes mittels anhydridfreier Härtung einsetzbar ist. Außerdem betrifft die Erfindung die Verwendung des Isolationswerkstoffes in Schaltanlagen, Transformatoren, Gießharztrockentransformatoren und/oder in dem entsprechenden Halbzeug einsetzbar ist. Dazu offenbart die Erfindung erstmals eine Vergussmasse mit einer Härterkomponente, durch die eine anionisch initiierte Homopolymerisation von sterisch gehinderten Epoxidharzen, was bislang nach dem Stand der Technik als nicht machbar galt, ermöglicht wird. Dazu werden so genannte Super-Basen mit einem pKB Wert größer 23 eingesetzt.
