Description
Verfahren zur Herstellung von härtbaren siliciumhaltigen Kunstharzen mit erhöhter Hydrolysenbeständigkeit Bei der Suche nach Kunststoffen mit höherer Wärmebeständigkeit für die Elektrotechnik ist man auf organische Siliciumverbindungen gestoßen, die beispielsweise aus Organopolysiloxanen, Kieselsäureestern oder deren Kombinationen mit rein organischen härtbaren Kunstharzen bestehen. Diese Stoffe sind jedoch, wie Versuche gezeigt haben, gegen hydrolytische Einflüsse mehr oder weniger stark empfindlich, so daß man also Isolationen aus solchen Stoffen kaum für feuchte Betriebe mit alkalischer Atmosphäre verwenden kann. Process for the production of curable silicon-containing synthetic resins with increased resistance to hydrolysis When looking for plastics with higher Heat resistance for electrical engineering is based on organic silicon compounds encountered, for example, from organopolysiloxanes, silicic acid esters or their There are combinations with purely organic hardenable synthetic resins. These substances however, as tests have shown, are more or less against hydrolytic influences less sensitive, so that one can hardly isolate it from such materials can be used for humid plants with an alkaline atmosphere.
Der Erfindung liegt die Aufgabe zugrunde, Harze mit erhöhter Hydrolysenbeständigkeit zu schaffen und dadurch das Anwendungsgebiet derartiger Isolationen auszuweiten. The invention is based on the object of providing resins with increased resistance to hydrolysis to create and thereby expand the field of application of such insulation.
Erfindungsgemäß werden bei der üblichen Umsetzung von freie Hydroxylgruppen aufweisenden ölmodifizierten. Alkydharzen mit Orthokieselsäureestern Orthokieselsäureester der Formel (RO)xSi(OX)4-z verwendet. Dabei ist R ein Aryl- oder nicht tertiärer Alkylrest, X ein tertiärer Alkylrest und x gleich 1 bis 3. According to the invention, free hydroxyl groups are used in the usual reaction containing oil-modified. Alkyd resins with orthosilicic acid esters Orthosilicic acid esters of the formula (RO) xSi (OX) 4-z is used. R is an aryl or non-tertiary Alkyl radical, X is a tertiary alkyl radical and x is 1 to 3.
Unter üblicher Umsetzung ist dabei folgendes zu verstehen: Wird beispielsweise ein solcher Stoff als Tränklack benutzt, dann findet beim Vermischen der Komponenten und anschließend bei Raumtemperatur kaum eine nennenswerte Umsetzung statt. Die eigentliche Umsetzung erfolgt erst bei der üblichen Aushärtung, also bei höheren Temperaturen. Wird aber ein solcher Stoff beispielsweise als Preßmasse, als halbfester Körper verwendet, dann kann eine teilweise Umsetzung durch entsprechende Wärmebehandlung vor der eigentlichen Verarbeitung erzielt werden, und die vollständige Umsetzung findet erst bei der Aushärtung statt. The following is to be understood under normal implementation: For example If such a substance is used as an impregnating varnish, then it takes place when the components are mixed and then hardly any significant conversion takes place at room temperature. the actual implementation only takes place during the usual hardening, i.e. at higher levels Temperatures. But if such a substance is used, for example, as a molding compound, as a semi-solid Body used, then can be a partial implementation through appropriate heat treatment can be achieved before the actual processing, and the full implementation only takes place during curing.
Es empfiehlt sich, Ester, die als Arylrest beispielsweise einen Phenyl- oder Kresylrest aufweisen, zu verwenden, der gegebenenfalls halogeniert, z. B. chloriert, sein kann. So eignen sich z. B. auch solche mit dem p-Chlorphenylrest. x kann mit Vorzug ein tertiärer Butyl- oder tertiärer Amylrest sein. It is advisable to use esters which, as an aryl radical, are, for example, a phenyl or have cresyl radical, to be used, which is optionally halogenated, for. B. chlorinated, can be. So are z. B. also those with the p-chlorophenyl radical. x can with Preferred be a tertiary butyl or tertiary amyl radical.
Diese Stoffe können als Kunststoffe in der Elektrotechnik für übliche Zwecke, also z. B. als Lackanstrich, Tränklack, Füllung von Geräten, Klebemittel, Preßmasse, verwendet werden. These substances can be used as plastics in electrical engineering for usual Purposes, e.g. B. as varnish, impregnating varnish, filling of devices, adhesives, Molding compound, can be used.
Beispiel 800 g eines ölmodifizierten Polyesterharzes werden in 800 g Testbenzin gelöst und erfindungsgemäß mit einer Lösung von 200 g o-Kieselsäure-diphenyl- ditert.butylester in 200 g Testbenzin vermischt. Die Umsetzung des Polyesterharzes und des eben gegenannten Orthokieselsäureesters beginnt sehr langsam schon beim Vermischen und schreitet bei Raumtemperatur langsam fort. Die Hauptumsetzung findet erst bei der Wärmebehandlung bzw. Aushärtung dieser Masse statt. Example 800 g of an oil-modified polyester resin are used in 800 g of white spirit dissolved and according to the invention with a solution of 200 g of o-silicic acid diphenyl ditert.butyl ester mixed in 200 g white spirit. The implementation of the polyester resin and the just opposite Orthosilicic acid ester begins very slowly during mixing and progresses slowly proceed at room temperature. The main implementation only takes place during the heat treatment or hardening of this mass takes place.
