Description

Elektrisches Imprägniermittel oder Isolierstoff Es ist ein Verfahren vorgeschlagen worden, nach dem durch Umsetzung von Verbindungen des Typs Si (OR)mCln mit höhermolekularen Mono-oder Dicarbonsäuren siliciumhaltige Wachse hergestellt werden können. 0R können dabei Alkoxy-, Aroxy- und Aralkoxygruppen sein. Al:s besonders vorteilhaft können zur Synthese höhermolekularer Wachse Siliciumverbindungen desTyps Si (OR)2C12 oder Si (OR)3Cl Verwendung finden. Als Carbonsäuren können die gleichen wie diejenigen der natürlichen oder synthetischen Wachse herangezogen werden, beispielsweise Stearinsäure, Palmitinsäure usw. Diese Verbindungen werden vorteilhaft bei Temperaturen, die zwischen 8o und 25o° liegen, umgesetzt. Das Reaktionsprodukt wird z. B. in einem organischen Lösungsmittel, wie Trichloräthylen, gelöst und gegebenenfalls mit Hilfe von Aktivkohle bei Siedetemperatur gereinigt. Das Reaktionsprodukt stellt ein Wachs hoher Wärmebeständigkeit dar, das bei thermischer Behandlung ausgehärtet werden kann.Electrical impregnant or insulating material.It is a process been proposed after the reaction of compounds of the type Si (OR) mCln silicon-containing waxes produced with higher molecular weight mono- or dicarboxylic acids can be. OR can be alkoxy, aroxy and aralkoxy groups. Al: s special Advantageously, for the synthesis of higher molecular weight waxes, silicon compounds of the type Si (OR) 2C12 or Si (OR) 3Cl are used. As carboxylic acids can be the same how those of the natural or synthetic waxes are used, for example Stearic acid, palmitic acid etc. These compounds are advantageously used at temperatures which are between 8o and 25o °, implemented. The reaction product is z. B. in one organic solvents such as trichlorethylene, dissolved and optionally with the help Purified from activated carbon at boiling temperature. The reaction product is a wax high heat resistance, which are cured during thermal treatment can.

Die Erfindung betrifft eine besonders vorteilhafte Anwendungsform dieser Wachse. Erfindungsgemäß werden Reaktionsprodukte von Verbindungen des Typs Si (0R). Cln, insbesondere Si (0R)3 Cl, die mit höhermolekularen Mono- oder Dicarbonsäuren umgesetzt werden, wobei 0R Alkoxy-, Aroxy- und Aralkoxygruppen sein können, als elektrische Imprägniermittel oder Isolierstoffe verwendet.The invention relates to a particularly advantageous form of application these waxes. According to the invention, reaction products of compounds of the type Si (0R). Cln, especially Si (OR) 3 Cl, the with higher molecular weight Mono- or dicarboxylic acids are reacted, with OR being alkoxy, aroxy and aralkoxy groups can be used as electrical impregnating agents or insulating materials.

Beispiel Ein nach der erwähnten Methode hergestelltes siliciumhaltiges Wachs, das einen Schmelzpunkt von etwa 16o° hat, wird auf i75° erwärmt und damit eine Feldspule imprägniert, deren Drähte mit Glasseide umsponnen sind. Nach Beendigung des in üblicher Weise durchgeführten Imprägniervorganges zeigt die Spule einen lückenlosen Wachsüberzug, der sich durch große thermische Stabilität auszeichnet.Example A silicon-containing product produced by the method mentioned Wax, which has a melting point of around 160 °, is heated to 175 ° and thus impregnated a field coil, the wires of which are wrapped with fiberglass. After completion of the impregnation process carried out in the usual way, the coil shows a gapless one Wax coating, which is characterized by great thermal stability.
