Description

Verfahren zum Kondensieren und Härten von Kunstharzen In der Lacktechnik werden Filmbildner verwendet., die- durch Erhitzen in ihren chemischen undphysikalischenEigenschaften verändert werden. Die Lackierungen können dadurch z. B. härter und beständig gegen Chemikalien werden. Die Härtung ist meist ein ziemlich zeitraubender Prozeß, der durch zugesetzte Beschleuniger verkürzt «erden kann. Die Verminderung der Härtezeit ist von ausschlaggebender Bedeutung für -die Wirtschaftlichkeit des Härteverfahrens, da dann vor allem die nötigen. Heizvorrichtungen besser ausgenutzt werden können.Process for condensing and hardening synthetic resins in paint technology film formers are used, which - by heating in their chemical and physical properties to be changed. The paintwork can thereby z. B. harder and resistant to Chemicals will be. The hardening is usually a rather time consuming process shortened by added accelerators «can be grounded. The reduction of the hardening time is of decisive importance for -the economic efficiency of the hardening process, then above all the necessary ones. Heating devices can be better utilized.

Es wurde ein Verfahren gefunden, welches ermöglicht, durch den Zuslatz von besonders wirksamen, Beschleunigern den Zeitaufwand wesentlich zu verkürzen und die Kondensation der Harze zu verbessern. Es besteht darin, dar dein durch Erhitzung zu kondensierenden Kunistharze.n als Beschleuniger geringe Mengen Alulniniumchela:te, wie Alumi@niumacetylace-tonat, Aluminiummalonsäureester, zugesetzt werden. Die angewandten: Mengen liegen annähernd um o,oi °/o, da größere Mengen oft ungünstig wirken. Für die Kondensation. komm-en: z. B.. Phenolal:deliyd'kompositionell, Alkydharze in Betracht, die. durch Beschleuniger kondensiert und gehärtet werden können. Man kann die Harze in. den üblichen Anwendungsformen verwenden, z. B. als Lösungen. Emulsionen, Dispersionen..A method has been found which enables the addition of particularly effective accelerators to significantly reduce the time required and to improve the condensation of the resins. It consists in daring your by heating Synthetic resins to be condensed as accelerators, small amounts of aluminum chelates, such as aluminum acetylacetonate, aluminum malonic acid ester, can be added. The applied: Quantities are approximately o, oi per cent, since larger quantities often have an unfavorable effect. For the condensation. come: z. B. Phenolal: deliyd'kompositionell, Alkydharze in Consider that. can be condensed and hardened by accelerators. One can Use the resins in the usual application forms, e.g. B. as solutions. Emulsions, Dispersions ..

Beispiel i Eine Lösung eines, häirtbaren Phenolharzes wird mit o,oi °/o eines Aluminiumchelates, wieAluminiumacetylacetonat öderAluminiummalonsäureester, versetzt. Mit der Lösung wird ein Gegenstand lackiert, der dann einige Sekunden auf i5o° erhitzt wird; die Härtung erfolgt ,in dieser lcurzm Zeit. Wird kein, Beschleuniger zugesetzt, so werden mehrere Minuten Hir das Einbrennen blenötigt.Example i A solution of a hardenable phenolic resin is given with o, oi ° / o of an aluminum chelate such as aluminum acetylacetonate or aluminum malonic acid ester, offset. An object is painted with the solution, which then takes a few seconds heated to 150 °; the hardening takes place in this short time. Not going to accelerate added, it takes several minutes to burn in.

Beispiele Eine Lacklösung, welche Polyvinylacetal und ein Phenroilfo@rrnaldehyäha,rz enthält, wird mit o,oi °/o Aluminiumacetylacetonat, bezogen auf die, angtwandten Harze, versetzt. Ein mit diesem Lack überzogener Gegenstand wird nach demVerdunsten deas Löisiungisirnittels auf i8o° erhitzt, wobei der Lacküberzug in überraschend kurzer Zeit erhärtet. EXAMPLES A varnish solution which contains polyvinyl acetal and a phenolic acid hydrofluoric acid is admixed with 0.010 aluminum acetylacetonate, based on the resins used. One with this paint coated object becomes after evaporation the solution is heated to 180 °, the Lacquer coating hardened in a surprisingly short time.
