Description
Verfahren zur Verbesserung von Lacken und Anstrichmitteln. Es ist gefunden worden, dass durch Zu satz von Lösungen von Eisen-(III)-alkohola- ten, die durch Verbindungen, welche durch Keto-Enol=Tautomerie ausgezeichnet sind, zurr Beispiel Acetessigester, stabilisiert sind, Lacke und Anstrichmittel verbessert werden können.
Gegenstand des Patentes ist demnach ein Verfahren zur Verbesserung von Lacken und Anstrichmitteln, das dadurch gekennzeichnet ist, dass denselben Lösungen von Eisen-(III;- alkoholaten, die durch Verbindungen, welche sich durch Keto-Enol-Tautomerie auszeichnen, wie zum Beispiel Acetessigester, stabilisiert sind, zugesetzt werden.
Durch den Zusatz die ser Lösungen kann beispielsweise bei trocknen den ölen oder Lacken aus Lackharzen mit reaktionsfähigen, zum Metallalkoholateinbau befähigten Gruppen, wie zum Beispiel Doppel bindungen oder sauren Methylengruppen, eine wesentliche Beschleunigung des 'Trocknungs- vorganges, eine Erhöhung der Filmfestigkeit und Filmhärte und auch eine ausgeprägte Rostschutzwirkung erzielt werden. Ferner kann ausser diesen technischen Vorteilen auch eine Einsparung von Metallen erzielt werden.
Beispiel: Leinöl-Standöl wird mit einer Lösung von mit Acetessigester stabilisiertem Eisen-III- Butylat in Benzol versetzt, bis das Gemisch, auf Trockenrückstand bezogen, 9,5 /o Eisen enthält. Der Trocknungsvorgang erfährt da durch eine wesentliche Beschleunigung. Ein Aufstrich zeigt nach Trocknung sehr gute Rostschutzeigenschaften und im Vergleich zu einem mit unbehandeltem Leinöl-Standöl er haltenen Aufstrich erhöhte Festigkeit und Härte.
Process for the improvement of lacquers and paints. It has been found that by adding solutions of iron (III) alcohols which are stabilized by compounds which are characterized by keto-enol = tautomerism, for example acetoacetic ester, varnishes and paints can be improved.
The subject of the patent is therefore a process for the improvement of varnishes and paints, which is characterized in that the same solutions of iron (III; - alcoholates, which are characterized by compounds that are characterized by keto-enol tautomerism, such as acetoacetic ester, are stabilized, are added.
By adding these solutions, for example, when drying oils or paints made from varnish resins with reactive groups capable of incorporating metal alcoholate, such as double bonds or acidic methylene groups, a substantial acceleration of the drying process, an increase in film strength and film hardness and also a pronounced rust protection effect can be achieved. In addition to these technical advantages, it is also possible to save metals.
Example: linseed oil stand oil is mixed with a solution of iron (III) butylate stabilized with acetoacetic ester in benzene until the mixture, based on the dry residue, contains 9.5% iron. The drying process is accelerated considerably. After drying, a spread shows very good anti-rust properties and, in comparison to a spread obtained with untreated linseed oil stand oil, increased strength and hardness.
