Description
Verfahren zur Herstellung von Gegenständen aus Glimmerschüppchen und Kieselsäureestern aliphatischer Alkohole, insbesondere Polykieselsäureestern Es ist bekannt, Glimmer gegebenenfalls nach vorherigem Erhitzen und Abschrecken in feinste Schüppchen aufzulösen und ihn zusammen mit einem Bindemittel, ähnlich wie in der Papierindustrie, zu Folien, Tafeln od. dgl. zu verarbeiten. Die so gewonnen Teile zeichnen sich durch große Hitzebeständigkeit aus, haben hervorragende elektrische Eigenschaften und werden deshalb als hochbeanspruchtes Dielektrikum in elektrischen Geräten verwendet.Process for the production of objects from mica flakes and Silicic acid esters of aliphatic alcohols, in particular polysilicic acid esters Es is known to convert mica into, if necessary, after prior heating and quenching to dissolve the finest flakes and put it together with a binding agent, similar to in the paper industry, to make foils, panels or the like. That won Parts are distinguished by great heat resistance, have excellent electrical properties Properties and are therefore used as a highly stressed dielectric in electrical Devices used.
Ferner ist die Herstellung von Formkörpern aus Glimmerschüppchen und aliphatischen Estern der Kieselsäure bekannt. Diese Ester werden in wässerige kolloidale Sole, insbesondere alkoholische Sole der Kieselsäure übergeführt, und zwar durch Hydrolysation der Kieselsäureester mittels Einwirkung von flüchtigen Säuren, beispielsweise wässerige Kohlenwasserstoffsäure. Erst diese Sole werden mit dem Glimmer vermischt und anschließend getrocknet.Furthermore, the production of moldings from mica flakes and aliphatic esters of silicic acid known. These esters are colloidal in water Soles, in particular alcoholic sols of the silica converted, namely by Hydrolysis of the silicic acid ester by means of the action of volatile acids, for example aqueous hydrocarbon acid. Only this brine is mixed with the mica and then dried.
Weiterhin ist die Herstellung von haltbaren wässerigen Emulsionen von Estern der Kieselsäuren bekannt, die zur Herstellung von Formkörpern verwendet werden können, indem man z. B. Sillimanit mit dem gleichen Volumen einer wässerigen Emulsion eines Kieselsäureesters vermischt und das Gemisch verformt. Die Formkörper können so hoch erhitzt werden, daß man ein Kieselsäureskelett als Bindemittel erhalten kann. Es müssen hier aber zunächst wässerige Emulsionen der Kieselsäureester hergestellt werden.Furthermore, the production of durable aqueous emulsions of silicic acid esters known, which are used for the production of moldings can be done by z. B. Sillimanit with the same volume of an aqueous Mixed emulsion of a silicic acid ester and the mixture is shaped. The moldings can be heated so high that a silica skeleton is obtained as a binding agent can. In this case, however, aqueous emulsions of the silicic acid esters have to be produced first will.
Bei einem Verfahren zur Herstellung von Gegenständen aus Glimmerschüppchen und Kieselsäureestern aliphatischer Alkohole, insbesondere Polykieselsäureestern, bringt man erfindungsgemäß Glimmerschüppchen mit den Kieselsäureestern unmittelbar in Berührung, beispielsweise durch Mischung, verformt das Gemisch und erhitzt alsdann die Gegenstände so hoch und so lange, bis die Ester sich zersetzen und Kieselsäure als Bindemittel zurückbleibt. Infolge des Fehlens von Wasser und Säure bei der Herstellung solcher Körper sind diese elektrisch wertvoller als die nach bekannten Verfahren hergestellten Körper. Das Verfahren zeichnet sich durch besondere Einfachheit aus. Die verwendeten Ausgangsstoffe sind wesentlich wohlfeiler und leichter herzustellen als Silicone. Die Körper halten überraschend gut der Hitze stand, weil die bei der Erhitzung sich bildende Kieselsäure nach der Abscheidung der organischen Bestandteile des Esters die Glimmerteilchen fest zusammenhält. Auf diese Weise hergestellte Glimmerkörper, z. B. Folien, sind so fest, daß sie wie Metall klingen. Man kann einen solchen Stoff auch als Anstrichmittel verwenden, insbesondere wenn man Glimmerschüppchen höchster Feinheit benutzt, falls der bestrichene Gegenstand der Hitzebehandlung genügend standhält. Im Anstrich setzen sich die Schüppchen mehr oder weniger geordnet in Schichten ab, jedenfalls leidet die elektrische Festigkeit nicht, wenn man die Schüppchen mehr und mehr verkleinert. Ein solcher eingebrannter Anstrich ist nach dem Erhärten elektrisch und thermisch sehr widerstandsfähig und hält auch der Feuchtigkeit stand.In a process for the production of objects from flakes of mica and silicic acid esters of aliphatic alcohols, in particular polysilicic acid esters, according to the invention, mica flakes are brought directly with the silicic acid esters in contact, for example by mixing, the mixture is deformed and then heated the objects so high and so long until the esters decompose and silica remains as a binder. As a result of the lack of water and acid in its manufacture Such bodies are electrically more valuable than those according to known processes manufactured body. The process is characterized by its particular simplicity. The raw materials used are much cheaper and easier to manufacture than silicones. The bodies withstand the heat surprisingly well because the Heating of the silicic acid that forms after the separation of the organic components of the ester holds the mica particles tightly together. Mica bodies made in this way, z. B. Foils are so strong that they sound like metal. You can have such a substance Also use as a paint, especially if you have the highest mica flakes Delicacy used in case the coated object of heat treatment is sufficient withstands. In the paint, the scales settle in more or less orderly Layers off, in any case the electrical strength does not suffer if you remove the flakes more and more downsized. Such a baked-on paint is after it has hardened electrically and thermally very resistant and also withstands moisture.
