Description
Lösungsmittel für Harze, insonderheit Kunstharze. Es ist bekannt, daß eyklische Ketone, wie beispielsweise das Cyklohexanon, ein gutes Lösungsvermögen für Harze, wie Dammar, Kopal- und Fichtenharz, besitzen, während die entsprechenden Alkohole, z. B. das Cyklohexanol und seine Homologen, für diesen Zweck bisher nicht benutzt sind: Der Grund hierfür ist offenbar in der Dickflüssigkeit und relativ geringen Flüchtigkeit der Cyklohexanole zu suchen, wie dies auch im Patent 25135I hinsichtlich ihrer Unverwendbarkeit für die Herstellung von Zaponlacken des näheren ausgeführt ist-Es wurde nun gefunden, daß das Cyklohexanol und seine Homologen sowohl allein als auch in Mischung mit Benzolkohlenwasserstoffen, Benzinen, chlorierten Kohlenwasserstoffen und hydrierten Naphthalinen ein ganz, ausgezeichnetes Lösungsvermögen für Harze besitzen und insbesondere die überraschende Eigenschaft zeigen, Kondensationsprodukte der Phenole mit Formaldehyd (Kunstharze), die bekanntlich in zahlreichen Lösungsmitteln wenig oder gar nicht löslich sind, leicht aufzulösen, ja sogar als Zusatz zu Nichtlösern klare und haltbare Lösungen dieser Phenolabkömmlinge zu liefern. .Dabei ist die Flüchtigkeit der genannten Verbindungen besonders dann eine durchaus genügende, wenn sie im Gemisch mit anderen, schneller verdunstenden Mitteln, die an sich aber das obengenannte Lösungsvermögen nicht besitzen müssen, zur Anwendung gelangen. Beispiel 1. 7o Gewichtsteile Dekahydronaphthalin werden mit So Gewichtsteilen Cyklohexanol versetzt und 75 Gewichtsteile eines durch Koncl_ensation von Phenol mit Formaldehyd erhaltenen Kunstharzes in dieser Mischung aufgelöst. Die dickflüssige Lösung ist zum Lackieren von Holzteilen u. dgl. ohne weiteres geeignet, da sie nicht langsamer trocknet wie die bekannten Terpentinlacke und auch ohne Leinölzusatz das Harz in Form eines klaren, von der Unterlage schwer entfernbaren Überzuges hinterläßt.Solvents for resins, especially synthetic resins. It is known, that eyklische ketones, such as cyclohexanone, have good solvent power for resins such as dammar, copal and spruce resin, while the corresponding Alcohols e.g. B. Cyclohexanol and its homologues, not yet for this purpose are used: The reason for this is obviously in the thickness and relative to look for low volatility of the cyclohexanols, as is also the case in patent 25135I regarding their unsuitability for the production of zapon varnishes of the closer It has now been found that the cyclohexanol and its homologues both alone as well as in a mixture with benzene hydrocarbons, gasoline, chlorinated Hydrocarbons and hydrogenated naphthalenes have a very, excellent solvent power for resins and in particular show the surprising property of condensation products the phenols with formaldehyde (synthetic resins), which are known in numerous solvents are little or not at all soluble, easy to dissolve, even as an additive to nonsolvents to deliver clear and durable solutions of these phenol derivatives. .The Volatility of the compounds mentioned, especially a sufficient, when mixed with other, faster evaporating agents, but that in itself do not have to have the above-mentioned solvent power to be used. Example 1. 70 parts by weight of decahydronaphthalene are mixed with 50 parts by weight of cyclohexanol added and 75 parts by weight of one by Koncl_ensation of phenol with formaldehyde obtained synthetic resin dissolved in this mixture. The thick solution is Suitable for painting wooden parts and the like, as they are not slower dries the resin in like the well-known turpentine lacquers and without the addition of linseed oil Leaves the form of a clear coating that is difficult to remove from the substrate.
An Stelle des hier verwandten Kunstharzes können, wie schon erwähnt, auch Naturharze, wie Dammar, Fichtenharz u. @dgl., gegebenenfalls in ungeschmolzenem Zustande, an Stelle des Cyklohexanols auch seine Homologen (Methylcyklohexanole), an Stelle des hier als Verdünnungsmittel angewandten D:ekahydronaphthalins auch andere Kohlenwasserstoffe, wie höher siedende Benzole, Tetrahydronaphthalin (Tetralin), .Benzin u. dgl., Verwendung finden, und schließlich kann auch ohne. den Zusatz eines Verdünnungsmittels gearbeitet werden. Beispiel a. 5o Gewichtsteile ungeschmolzenen Kaurikopals werden- in 3o Gewichtsteilen eines durch Hydrierung von Trikresol gewonnenen Methylcyklohexanolgemisches gelöst und mit 3o bis 4o Gewichtsteilen einer höher siedenden Solventnaphtha verdünnt. Die erhaltene dickflüssige Lösung ist- sowohl an sich als auch nach Zugabe geeigneter Öle, wie Standöl und Dicköl, für Lackierungszwecke, nach weiterem Zusatz an Farbstoffen auch für Farbanstriche geeignet.Instead of the synthetic resin used here, as already mentioned, also natural resins such as dammar, spruce resin and the like, possibly in unmelted Conditions, instead of cyclohexanol also its homologues (methylcyclohexanols), in place of the d: ekahydronaphthalins used here as a diluent other hydrocarbons, such as higher-boiling benzenes, tetrahydronaphthalene (tetralin), .Petrol and the like, find use, and finally can also without. the addition of a Diluent to be worked. Example a. 5o parts by weight unmelted Kauricopals are obtained in 3o parts by weight by hydrogenating tricresol Methylcyklohexanolgemisches dissolved and with 3o to 4o parts by weight a higher boiling solvent naphtha. The viscous solution obtained is- both per se and after adding suitable oils, such as stand oil and thick oil, for painting purposes, after further addition of dyes also for paint coatings suitable.
