Description

Lösungs-, Weichmachungs-, Gelatinierungs- und Quellungsmittel für Aminoplaste Gegenstand des Patents 893 261 ist die Verwendung von Monoäthern mehrwertiger aliphatischer Alkohole mit cycloaliphatischen Alkoholen mit mindestens 6 oder höhermolekularen aliphatischen Alkoholen mit mindestens 8 Kohlenstoffatomen als Lösungs-, Weichmachungs-, Gelatinierungs- und Quellungsmittel für Aminoplaste. Wie nun weiterhin gefunden wurde, lassen sich mit mindestens gleich gutem Erfolg auch diejenigen Äther mehrwertiger aliphatischer Alkohole für den angegebenen Zweck verwenden, in denen mehr als eine Hydroxylgruppe mit einem höhermolekularen aliphatischen oder cycloaliphatischen Alkohol veräthert, aber wenigstens noch eine freie Hydroxylgruppe vorhanden ist. Solche Äther sind z. B. Glycerin-a, a'-di-n- oder . -iso-hexyläther, Glycerina, a'-dicyclohexyläther, Pentaerythritdi- oder -trioctyläther, Dipentaerythrit-tetrahexyläther, der Din-butyläther des Trimethylolpropans, der Pentapropyläther des Sorbits u. a. Derartige Verbindungen sind aus der Literatur bekannt und werden in bekannter und üblicher Weise, z. B. aus mehrwertigen aliphatischen Alkoholen bzw. deren Alkalimetallverbindungen und Alkyl- bzw. Cycloalkylhalogeniden, erhalten.Solvents, softeners, gelling agents and swelling agents for Aminoplasts The subject of patent 893 261 is the use of monoethers of polyvalent ones aliphatic alcohols with cycloaliphatic alcohols with at least 6 or higher molecular weight aliphatic alcohols with at least 8 carbon atoms as solvents, plasticizers, Gelatinizing and swelling agents for aminoplasts. As found now those ethers can also be made more valuable with at least equal success Use aliphatic alcohols for the specified purpose, in which more than one Hydroxyl group with a higher molecular weight aliphatic or cycloaliphatic Alcohol is etherified, but at least one free hydroxyl group is still present. Such ethers are z. B. glycerin-a, a'-di-n- or. -iso-hexyl ether, glycerina, a'-dicyclohexyl ether, pentaerythritol di or trioctyl ether, dipentaerythritol tetrahexyl ether, the din-butyl ether of trimethylolpropane, the pentapropyl ether of sorbitol and others. Such compounds are known from the literature and are known in and usual way, e.g. B. from polyhydric aliphatic alcohols or their alkali metal compounds and alkyl and cycloalkyl halides, respectively.

Die Polyäther mehrwertiger Alkohole sind gut mit den Aminoharzen verträglich und lassen sich leicht in dieselben einarbeiten, auch wenn noch andere hochpolymere Stoffe zugegen sein sollten.The polyethers of polyhydric alcohols are well compatible with the amino resins and can be easily converted into incorporate the same, even if still other high polymer materials should be present.

Beispiele i. Zu einer Auflösung von io Gewichtsteilen Harnstoff in ioo Gewichtsteilen einer wäßrigen Lösung von Formaldehyd (spezifisches Gewicht i,og2) werden 5 Gewichtsteile Glycerin-dihexyläther hinzugefügt und die Mischung durch Zugabe von Phosphorsäure sauer (PH = 3 bis 4) eingestellt. Nach Bildung des Vorkondensates bei gewöhnlicher Temperatur wird das Gemisch auf Papier- oder Gewebebahnen aufgebracht und durch Hitzebehandlung eine wasserfeste elastische Imprägnierung erzielt.Examples i. To dissolve 10 parts by weight of urea in 100 parts by weight of an aqueous solution of formaldehyde (specific weight i, og2) 5 parts by weight of glycerol dihexyl ether are added and the mixture through Addition of phosphoric acid adjusted to acidic (PH = 3 to 4). After the pre-condensate has formed at ordinary temperature the mixture is applied to paper or fabric webs and a waterproof elastic impregnation is achieved through heat treatment.

2. Zum Verleimen von Furnierhölzern dient eine Lösung von igo Gewichtsteilen Melamin in i2oo Gewichtsteilen neutralem wäßrigem 3o°/Qigem Formaldehyd, der vor der Bildung des Vorkondensationsproduktes ioo Gewichtsteile Dipentaerythrit-trioctyläther zugesetzt sind.2. A solution of igo parts by weight is used to glue veneers Melamine in 100 parts by weight of neutral aqueous 30% formaldehyde, which is before the formation of the precondensation product 100 parts by weight of dipentaerythritol trioctyl ether are added.

3. Setzt man einer Lösung von 5o Gewichtsteilen handelsüblichem Harnstoff-Formaldehydharz in 5o Gewichtsteilen g6°/Qigem Äthylalkohol io Gewichtsteile Glycerin-dihexyläther zu, so erhält man einen Lack, der nach dem Auftrocknen einen klaren haftfesten elastischen Film liefert.3. A solution of 50 parts by weight of commercially available urea-formaldehyde resin is used in 50 parts by weight of 6% ethyl alcohol 10 parts by weight of glycerol dihexyl ether to, the result is a varnish which, after drying, has a clear, adhesive, elastic Film supplies.
