"Verfahren zur Herstellung modifizierter Aminoplaste.""Process for the preparation of modified aminoplasts."
Die Erfindung bezieht sich auf Umsetzungsprodukte, die durch ein Verfahren zur Herstellung modifizierter Aminoplaste er halten werden, indem Hexamethoxymethylmelamin mit aromatischen Garbonsäuren oder deren Derivaten umgesetzt wird, sowie auf die Weiterkondensation dieser Umsetzungsprodukte nach dem Aufbringen auf eine Unterlage in Gegenwart anderer an sich bekannter Lackrohstoffe.The invention relates to reaction products by a process for the production of modified aminoplasts can be obtained by adding hexamethoxymethylmelamine with aromatic Carboxylic acids or their derivatives is implemented, as well as the further condensation of these reaction products after application on a base in the presence of other known paint raw materials.
Geeignete' aromatische Garbonsäuren sind u. a. Benzoesäure bzw. deren Derivate, z. B. p-tert-Butylbenzoesäure; Polycarbonsäuren bzw. deren Derivate, z. B. Phthalsäure, Phthalsäure-anhydrid, Isophthalsäure, Hexahydrophtnalsäure-anhydrid, Benzoltricarbonsäure, Benzöltetracarbonsäure-dianhydrid.Suitable aromatic carboxylic acids include: Benzoic acid or their derivatives, e.g. B. p-tert-butylbenzoic acid; Polycarboxylic acids or their derivatives, e.g. B. phthalic acid, phthalic anhydride, Isophthalic acid, hexahydrophthalic anhydride, benzenetricarboxylic acid, Benzol tetracarboxylic acid dianhydride.
Die neuen Umsetzungsprodukte sind von relativ niedriger Viskosität und selbst lösungsmittelfrei bei Raumtemperatur ohne kristalline Ausscheidungen lagerstabil sowie in vielen organischen Lösungsmitteln löslich. Die Umsetzungsprodukte sind organophiler als Hexamethoxymethylmelamin und nicht ohne weiter Zusätze wassermischbar.The new reaction products are of relatively low viscosity and even solvent-free at room temperature without crystalline precipitates are storage-stable and soluble in many organic solvents. The conversion products are more organophilic than hexamethoxymethylmelamine and not without further Water-miscible additives.
Die Vorteile der neuen Umsetzungsprodukte zeigen sich auch in Kombination mit anderen Lackrohstoffen, z. B. Acrylharzen, Alkyd harzen, Epoxidharzen. Entsprechende Kombinationen zeigen überlegene Korrosions-, Wasser- und Witterungsbeständigkeit bei her vorragenden mechanischem Eigenschaften und hohem Festkörpergehalt. Sie können auch lösungsmittelfrei angewendet werden. EbenThe advantages of the new conversion products can also be seen in combination with other coating raw materials, e.g. B. acrylic resins, alkyd resins, epoxy resins. Corresponding combinations show superior resistance to corrosion, water and weathering excellent mechanical properties and high solids content. They can also be used without solvents. Just
so können bei diesen Kombinationen weitere an sich bekannte so with these combinations further known ones can be used
Lackrohstoffe, z. B. Pigmente, Lösungsmittel, Amine, andere Harze, -z. B. Phenol-Formaldehydkondensate, mitverwendet werden, und sich nach dem Aufbringen auf eine Unterlage eine Weiterkondensation im Film, z. B. durch thermische Nachbehandlung, anschließen. Paint raw materials, e.g. B. Pigments, solvents, amines, others Resins, -z. B. phenol-formaldehyde condensates, are also used, and further condensation in the film, e.g. B. by thermal aftertreatment, connect.
