Description

Lacke, insbesondere Polierlacke Es -wurde gefunden, daß Lacke, die Polykondensationsprodukte aus Cyolohexylurethan, Harnstoff und Formaldehyd enthalten, besonders wertvolle Eigenschaften besitzen.Lacquers, especially polishing lacquers It has been found that lacquers that Contain polycondensation products from cyolohexyl urethane, urea and formaldehyde, have particularly valuable properties.

Die genannten Polykondensationspr6dukte sind z. B. nach dem Verfahren des Patents 947:204-erhältlich. Sie sind insbesondere in Spiritus klar löslich. Aus solchen Lösungen hergestellte Anstriche sind vergleichbaren Anstrichen, z. B. solchen aus natürlichen Harzen, wie Schellack, oder aus künstlichen Harzen, wie Produkten aus Acetophenon . oder Cyclohexanon oder Äthylurethan und - Formaldehyd sowie Phenolformaldehyd- oder Harnstofform@al.dehydkondensa-, tionsprodukten, durch einen verhältnismäßig hohen Erweichungspunkt (etwa i--o°) bei gleichzeitigem engem plastischem Bereich .und- hervorragender Härte überlegen. Die genannten Polykondensationsprodukte eignen sich daher, insbesondere in Kombination mit geeigneten Weichmachern, wie Benzylbutylphthalat, Dioctylphthalat, Phthalsäureglykolen und Trimethylolpropanadipat und bzw. oder Weichharzen.. sowie gegebenenfalls Nitrocellulose hervorragendals Polierlacke für Holz oder Metallbleche. Mit diesen Polierlacken ausgeführte Anstriche können nicht nur von Hand, sondern auch mechanisch poliert werden, da sie schwabbelfest sind. Bei . Bearbeitung mit Polieröl tritt keine Schleierbildung auf. Außerdem besitzen Anstriche, welche die genannten Kondensationsprodukte enthalten, ähnlich wie solche, die aus den bekannten. Urethanharzen bestehen, hohe Wetterbeständigkeit und Lichtechtheit.The polycondensation products mentioned are e.g. B. after the procedure of Patent 947: 204- available. In particular, they are clearly soluble in alcohol. Paints made from such solutions are comparable paints, e.g. B. those made from natural resins such as shellac, or from synthetic resins such as Acetophenone products. or cyclohexanone or ethyl urethane and formaldehyde as well as phenol formaldehyde or urea form@al.dehydkondensa-, throughput products a relatively high softening point (about i - o °) with simultaneous tightness plastic range and superior hardness. The polycondensation products mentioned are therefore suitable, especially in combination with suitable plasticizers, such as Benzyl butyl phthalate, dioctyl phthalate, phthalic acid glycols and trimethylol propane adipate and / or soft resins .. as well as optionally nitrocellulose outstanding than Polishing varnishes for wood or sheet metal. Coatings made with these polishing varnishes can not only be polished by hand, but also mechanically, as they are wobbly resistant are. At . Processing with polishing oil does not result in fogging. Also own Paints which contain the condensation products mentioned, similar like those from the known. Urethane resins are made of, high weather resistance and lightfastness.

Es ist zwar schon bekannt, Lacküberzüge dadurch herzustellen, daß man auf die zu lackierenden Unterlagen Lösungen aufstreicht, die, gegebenenfalls zusammen mit Weichmachern und Pigmenten, zwei verschiedene Stoffe enthalten, nämlich einerseits Verbindungen, die im Molekül zwei Urethanreste enthalten - z. B. auch Cyclohexylurethanderivate -, und andererseits filmbildende Stoffe, die im Molekül mit Urethangruppen umsetzungsfähige Gruppen enthalten - worunter z. B. auch Harnstoff-Formaldehyd-Harze zuverstehen sind-, und die Überzüge abschließend bei Temperaturen von etwa 15o° einzubrennen. Zum Unterschied hierzu stellen die in der vorliegenden Anmeldung beschriebenen Lacke keine Einbrennlacke dar, sondern Lacke, die bei Raumtemperatur physikalisch trocknen und, wie erwähnt, insbesondere als Polierlacke geeignet sind. Beispiel i Eine Mischung aus 5o Gewichtsteilen Cyclohexyl-#urethan-Harnstoff -Formaldehyd -Harz, 2.5 .Gewichtsteilen Tnimethylolpropanadipat und 75 Gewichtsteilen Spiritus ergibt einen ausgezeichneten Spirituslack. Beispieil 2 Ein Holzpoli,erlack besteht aus 23 Gewichtsteilen Nitrocellulose (mittelviskos), 35 °/a butanolfeucht, 9 Gewichtsteilen. Äthylacetat, 28 Gewichtsteilen Butylacetat, 6 Gewichtsteilen Athylglykol, 3o Gewichtsteilen Toluol, 4 Gewichtsteilen Butanol, 23 Gewichtsteilen Cyclohexylurethan-Harnstoff-Formaldehyd-Harz, i : i iri Toluol. gelöst, 7 Gewichtsteilen Trimethylolpropanadipat, i : i in Butylacetat gelöst.Although it is already known to produce lacquer coatings that one spreads solutions on the substrates to be painted, which, if necessary along with plasticizers and pigments, contain two different substances, viz on the one hand, compounds that contain two urethane residues in the molecule - z. Belly Cyclohexyl urethane derivatives -, and on the other hand film-forming substances in the molecule contain reactive groups with urethane groups - including z. B. also urea-formaldehyde resins are to be understood, and finally the coatings at temperatures of about 15o ° to burn in. In contrast to this, those described in the present application Lacquers are not stoving lacquers, but lacquers that are physically produced at room temperature dry and, as mentioned, are particularly suitable as polishing varnishes. example A mixture of 50 parts by weight of cyclohexyl urethane urea formaldehyde Resin, 2.5 parts by weight of dimethylol propane adipate and 75 parts by weight of alcohol makes an excellent spirit varnish. Example 2 A wooden poli that is made of varnish from 23 parts by weight of nitrocellulose (medium viscosity), 35 ° / a butanol moist, 9 parts by weight. Ethyl acetate, 28 parts by weight of butyl acetate, 6 parts by weight of ethylglycol, 3o parts by weight Toluene, 4 parts by weight of butanol, 23 parts by weight of cyclohexyl urea-formaldehyde resin, i: i iri toluene. dissolved, 7 parts by weight of trimethylolpropane adipate, i: i in butyl acetate solved.

Beispiel 3 Ein Autopolierlack besteht aus 23 Gewichtsteilen Nitrocellulose (mittelviskos), 35 °/o butanolfeucht, 9 Gewichtsteilen Äthylacetat, 6 Gewichtsteilen Äthylglykol, 28 Gewichtsteilen B.utylacetat, 3o Gewichtsteilen Toluol, 4 Gewichtsteilen Butanol, 37,5 Gewichtsteilen Cyclohexylumethan-Harnstoff-Formaldehyd-Harz, i : i in Xylol gelöst, 22,5 Gewichtsteilen ölreiches Ricinenalkylharz, i : i in Xylol gelöst, 4,5 Gewichtsteilen hochchloriertes Diphenyl, i : i in Toluol gelöst, 4,5 Gewichtsteilen Dibutylphthalat, 6,5 Gewichtsteilen Titanoxyd, 6,5 Gewichtsteilen Zinkweiß.Example 3 A car polishing lacquer consists of 23 parts by weight of nitrocellulose (medium viscosity), 35% moist butanol, 9 parts by weight of ethyl acetate, 6 parts by weight Ethyl glycol, 28 parts by weight of butyl acetate, 3o parts by weight of toluene, 4 parts by weight Butanol, 37.5 parts by weight of cyclohexylumethane-urea-formaldehyde resin, i: i Dissolved in xylene, 22.5 parts by weight of oil-rich ricinene alkyl resin, i: i in xylene dissolved, 4.5 parts by weight of highly chlorinated diphenyl, i: i dissolved in toluene, 4.5 Parts by weight of dibutyl phthalate, 6.5 parts by weight of titanium oxide, 6.5 parts by weight Zinc white.
