Description
"lösun smittelfreie Überzu smitteL" Aus den deutschen Auslegeschriften Nr. 1 101 667 und Nr. 1 231 833 sind lösungsmittelfreie kalthärtende oder ofentrocknende Überzugsmittel auf Basis von Aminoplasten und Weichmachungsmitteln bekannt."Solvent-free transfer agents" from the German Auslegeschriften No. 1 101 667 and No. 1 231 833 are solvent-free cold-curing or oven-drying ones Coating agents based on aminoplasts and plasticizers are known.
Zn weiterer Ausbildung dieser Erfindungen hat sich gezeigt, daß ausgezeichnete lösungsmittelfreie Überzugsmittel aus Mischungen von Umsetzungsprodukten von mit einwertigen Alkoholen mit 1-4 Kohlenstoffatomen verätherten Aminotriazin-Formaldehyd-Kondensationsprodukten und cyolisehen Carbonsäuren sowie fe-tsäurefreien hrdroxylgruppenhaltigen Polyestern mit einem Hydroxylgehalt von mindestens 4% bestehen.Zn further development of these inventions has been found to be excellent solvent-free coating agents made from mixtures of reaction products of with monohydric alcohols with 1-4 carbon atoms etherified aminotriazine-formaldehyde condensation products and cyolic carboxylic acids as well as free-acid-free hydroxyl-containing polyesters with a hydroxyl content of at least 4%.
Die neuen löaungsmittelfreien Überzugsmittel sind niedrigviskos, bei Raumtemperatur hervorragend lagerstabil und können als Einbrennlacke Gder nach Härterzusatz, beispielsweise Salzsäure, auch als kalthärtende Lacke verwendet werden.The new solvent-free coating agents are of low viscosity Excellent storage stability at room temperature and can be used as stoving lacquers after adding hardener, hydrochloric acid, for example, can also be used as cold-curing paints.
Besonders geeignete Umsetzungsprodukte sind solche aus Hexamethoxymethylmelamin und oyclischen Polycarbonsäuren, z. B. Phthalsäure, Benzoltricarbonsäure, Benzoltetracarboasäure oder deren Derivaten, z. B.. Anhydriden.Particularly suitable reaction products are those from hexamethoxymethylmelamine and cyclic polycarboxylic acids, e.g. B. phthalic acid, benzene tricarboxylic acid, benzene tetracarboic acid or their derivatives, e.g. B. Anhydrides.
Besonders geeignete fettsäurefreie hydroxylgruppenhaltige Polyester sind auf der Basis von aliphatischen und aro- matischen Dicarbonsäuren, uc r-. Adipinsäure, Phthaleäure, zweiwertiger und drei- oder mehrwertigen Alkoholon, z. ,B. 1,2-Propylenglycol, Glycerin, aufgebaut und haben einen Hydroxylgehalt von 8% und höher. Beispiel: A) 100 Teile Hexamethoxymethylmelamin werden in Gegenwart von tylol bei 80-12000 unter leichtem Vaeuum mit 16 Teilen Phthalsäureanhydrid bis zu einer Säurezahl von 10 umgesetzt. Das erhaltene Umsetzungsprodukt ist völlig klar und hat eine Viskosität von etwa 6 P. bei 200C.Particularly suitable fatty acid-free polyesters containing hydroxyl groups are based on aliphatic and aro- matic dicarboxylic acids, uc r-. Adipic acid, phthalic acid, dihydric and tri or polyhydric alcohols, e.g. , B. 1,2-propylene glycol, glycerine, and have a hydroxyl content of 8% and higher. Example: A) 100 parts of hexamethoxymethylmelamine are reacted with 16 parts of phthalic anhydride to an acid number of 10 in the presence of tylene at 80-12000 under slight vacuum. The reaction product obtained is completely clear and has a viscosity of about 6 P. at 200.degree.
B) Unter Verwendung von Zinkoctoat und hithiumnaphtenat als Katalysatoren wird ein hydroxylgruppenhaltiger Polyester aus Glycerin, 1,2-Propylenglycol, Phthalsäuresahydrid und Adipinsäure unter azeotropen Bedingungen und Verwendung von 3Cylol während 30-35 Stunden bei Temperaturen von 120-mal-mal 2200C hergestellt. Der fettsäurefreie hydroxylgruppenhaltige Polyester hat eine Säurezahl von 12 und eine Hydrozylzahl von 520, die Viskosität beträgt 75see./DIN 4 mm/200C, 75%ig in Äthanol. Nach Herstellung des Polyesters wird das Xylol-unter Vacuum abdestilliert.B) Using zinc octoate and lithium naphtenate as catalysts, a hydroxyl group-containing polyester is produced from glycerol, 1,2-propylene glycol, phthalic acid sahydride and adipic acid under azeotropic conditions and using 3-cylol for 30-35 hours at temperatures of 120 times 220 ° C. The fatty acid-free, hydroxyl-containing polyester has an acid number of 12 and a hydrocyl number of 520, the viscosity is 75 sea./DIN 4 mm / 200 ° C., 75% in ethanol. After the polyester has been produced, the xylene is distilled off in vacuo.
60 Teile des Umsetzungsproduktes A) werden jetzt mit 40 Teilen des fettsäurefreien, hydroaylgruppenhaltigen, lösungsmittelfreien Polyesters BZ vermischt. Anstriche werden 30 min. bei 13000, 10 min. bei 16000 oder wenige Minuten bei 20000 eingebrannt und zeichnen sich durch gute allgemeine lacktechnische Eigenschaften aus. Bei Verwendung als kalthärtender hack werden 10% eines Härters aus eineu Teil conc. Salzsäure (37%ig) und einem Teil Äthylalkohol verwendet. Anstriche auf Holz sind bereits nach wenigen Minuten staubtrocken und härten zu Lackfilmen von hoher Härte und sehr guter Elastizität. Diese Lackfilme lassen die Holzstruktur völlig unverändert erkennen und sind absolut lichtecht. Die Lagerstabilität nach Härterzusatz beträgt bei Raumtemperatur ca. 2 Tage.60 parts of the reaction product A) are now mixed with 40 parts of the fatty acid-free, hydroayl group-containing, solvent-free polyester BZ. Paintings will be 30 min. At 13000, 10 min. At 16,000 minutes or baked at 200 00 and are distinguished by good general coating properties. When used as a cold-curing hack, 10% of a hardener from a part of conc. Hydrochloric acid (37%) and a part of ethyl alcohol are used. Paints on wood are dust-dry after just a few minutes and harden to form paint films of high hardness and very good elasticity. These lacquer films show the structure of the wood completely unchanged and are absolutely lightfast. The storage stability after the addition of hardener is approx. 2 days at room temperature.
