Description
Isolierstoff der Elektrotechnik auf der Basis von polymeren Kieselsäureestern Die Erfindung bezieht sich auf die Anwendung polymerer Kieselsäureester hohen Molekulargeevichtes als Isolierstoff der Elektrotechnik. Gemäß einem anderweitigen Vorschlag erhält man solche Kieselsäureester, wenn man aromatische Orthokieselsäureester m@i.t Dioxydiphenylmethan oder -propan umestert.Electrical engineering insulating material based on polymeric silicic acid esters The invention relates to the use of polymeric silicic acid esters of high molecular weight as insulating material in electrical engineering. Receives according to another proposal one such silicic acid ester when one aromatic orthosilicic acid ester m@i.t dioxydiphenylmethane or propane transesterified.
Erfindungsgemäß werden diese Kieselsäureester als Isolierstoff der Elektrotechnik verwendet. Sie finden gemäß einer weiteren Ausgestaltung der Erfindung beispielsweise als Füllmasse für Hohlräume, die gegen Eintritt von Gasen und Feuchtigkeit zu schützen sind, Verwendung. Der Isolierstoff wird bei Erwärmung dünnflüssig, dringt also gut auch in die kleinsten Hohlräume, z. B. zwischen den einzelnen Drähten einer Wicklung und in Poren der Wicklungsisolation; ein. Er ist außerdem hitzebeständig, zeigt große Klebkraft und neigt nicht zum Sprödwerden und Ri-ssebilden. Er hat auch ,große elektrische Festigkeit. So kann man z. B. solche Isolierstoffe zum Füllen von Klemmenkästen elektrischer Geräte, zum Füllen der Gehäuse von Meßwandlern und ähnlicher Apparate verwenden. Er kann nach Erwärmung wieder aus dem Hohlraum entfernt werden.According to the invention, these silicic acid esters are used as the insulating material Electrical engineering used. You will find according to a further embodiment of the invention for example as a filling compound for cavities that protect against the entry of gases and moisture are to be protected, use. The insulating material becomes thin when heated and penetrates so also good in the smallest cavities, e.g. B. between the individual wires one Winding and in pores of the winding insulation; a. It is also heat resistant, shows high bond strength and does not tend to become brittle or crack. He also has , great electrical strength. So you can z. B. such insulating materials for filling of terminal boxes of electrical devices, for filling the housing of Use transducers and similar apparatus. It can be back off after warming up removed from the cavity.
Aus solchen Isolierstoffen können auch Filmbänder für elektrische Bauteile und Geräte hergestellt werden, oder man kann sie den zur Filmherstellung dienenden Stoffen beimengen. Soll z. B. die Wicklung eines elektrischen Gerätes mit solchen Isolierstoffen eingehüllt werden, dann wird diese Wicklung mit einer Schmelze dieses Isolierstoffes umgossen oder in einer solchen Schmelze getränkt, und anschließend wird das Ganze auf 35o bis .[oo° C etwa für 2 Stunden zwecks Vernetzung des Isolierstoffes erhitzt. Man erhält dadurch eine kautschukartige Umhüllung des elektrischen Gerätes. In derselben Weise können auch kautschukartige elektrische Formkörper hergestellt werden, oder man kann agressiven Flüssigkeiten ausgesetzte elektrische Bauteile und elektrische Leiter, z. B. Drähte, mit solchen Hüllen umgeben. Desgleichen werden solche Isolierstoffe mit Vorteil als isolierende Klebstoffe und isolierende Anstrichmittel in der Elektrotechnik verwendet, da sie besonders bei höheren Temperaturen noch beständig sind.From such insulating materials, film tapes for electrical Components and devices are manufactured, or they can be used for film production Add serving substances. Should z. B. the winding of an electrical device are encased with such insulating materials, then this winding is covered with a Melt of this insulating material poured around or soaked in such a melt, and then the whole thing is heated to 35o to [oo ° C for about 2 hours for the purpose of crosslinking of the insulating material is heated. This gives a rubber-like covering of the electrical device. In the same way, rubber-like electrical Shaped bodies can be produced, or they can be exposed to aggressive liquids electrical components and electrical conductors, e.g. B. wires, surrounded with such sheaths. Likewise, such insulating materials are used as insulating adhesives and with advantage insulating paints used in electrical engineering as they are particularly useful in higher temperatures are still resistant.
Es ist bereits bekannt, aus Orthokieselsäureestern durch Oxydation Polykieselsäureester herzustellen, die zwischen den Si-Atomen nur Sauerstoffbrücken aufweisen, während bei dem erfindungsgemäß verwendbaren Mittel der Abstand der Si-Atome im Kondensationsprodukt wesentlich größer ist, was die obengenannten Vorteile zur Folge hat.It is already known from orthosilicic acid esters by oxidation To produce polysilicic acid esters, the only oxygen bridges between the Si atoms have, while in the case of the agent which can be used according to the invention, the distance between the Si atoms in the condensation product is much larger, which leads to the advantages mentioned above Consequence.
