Description
Verfahren zur Herstellung von Kunstharzen. Es wurde gefunden, daß man -den Klebepunkt der \;aturharze wesentlich erhöhen kann, `nenn man synthetisch hergestellte, freie Carboxylgruppen enthaltende, harzartige Kondensationsprodukte mit Naturharzen verschmilzt ohne oder mit Zusatz von Oxyden, Hydroxyden oder Carbonaten der Erdalkalien. Von M. B o t t 1 e r (über Herstellung und Eigenschaften von Kunstharzen, Seite 28 und a9) ist das Verschmelzen von Naturharzen bzw. deren Salzen mit Aldehyd-Phenolharzen beschrieben. Das Verfahren gemäß vorliegender Erfindung dagegen besteht in dem Verschmelzen von Naturharzen mit solchen Kunstharzen, welche aus aromatischen Carbonsäuren erhalten werden bzw. im Molekül freie Carboxylgruppen besitzen, mit oder ohne Zusatz von Oxyden, Hydr oxy den oder Carbonaten der Erdalkalien. Bei diesem Verfahren erhält man im Gegensatz zu dem bisher bekannten, von Bottler beschriebenen Verfahren bei Verwendung der Carbonsäureharze ohne Zusatz von Erdalkaliverbindungen veredelte -Naturharze, welche neben einer gewissen Erhöhung des Klebepunktes, im Vergleich zu den in analogerWeise mitPhenolharzen erhaltenen, diesen gegenüber besonders den Vorzug zeigen, daß sie nicht wie diese eine dem angewandten Naturharze gegenüber verringerte Löslichkeit in Alkalien, sondern im Gegenteil eine erhöhte Löslichkeit besitzen. Diejenigen Harze der vorliegenden Erfindung, welche bei gleichzeitiger Anwesenheit von Erdalkaliverbindungen gewonnen werden, besitzen einen weit höheren Klebepunkt als die durch Verschmelzen mit Phenolharz erhaltenen. Beispiele: i. i oo Teile deutsches Fichtenharz werden geschmolzen und bei ioo bis i2o' unter Rühren 75 Teile des durch Kondensation von Salicylsäure mit Formaldehyd erhaltenen Harzes eingetragen. Die Temperatur wird langsam gesteigert bis igo bis 2oo'. Nach Erkalten der Schmelze erhält man ein klares, helles Harz, das sich sehr leicht in Soda und Ammoniak löst und dessen Klebepunkt um mindestens 3o' erhöht ist.Process for the production of synthetic resins. It has been found that - the sticking point of the natural resins can be increased significantly if synthetically produced, resin-like condensation products containing free carboxyl groups are fused with natural resins with or without the addition of oxides, hydroxides or carbonates of alkaline earths. M. Bott 1 er (on the production and properties of synthetic resins, page 28 and a9) describes the fusing of natural resins or their salts with aldehyde-phenolic resins. The method according to the present invention, however, consists in the fusing of natural resins with those synthetic resins which are obtained from aromatic carboxylic acids or have free carboxyl groups in the molecule, with or without the addition of oxides, hydrates or carbonates of alkaline earths. In this process, in contrast to the previously known process described by Bottler, when the carboxylic acid resins are used without the addition of alkaline earth compounds, refined natural resins are obtained which, in addition to a certain increase in the adhesive point, compared to those obtained in an analogous manner with phenolic resins, are particularly preferred over them show that they do not have a reduced solubility in alkalis as compared to the natural resins used, but on the contrary have increased solubility. Those resins of the present invention which are obtained in the simultaneous presence of alkaline earth compounds have a far higher sticking point than those obtained by fusing with phenolic resin. Examples: i. 100 parts of German spruce resin are melted and 75 parts of the resin obtained by condensation of salicylic acid with formaldehyde are introduced at 100 to 120 'with stirring. The temperature is slowly increased to igo to 2oo '. After the melt has cooled down, a clear, light-colored resin is obtained which dissolves very easily in soda and ammonia and whose sticking point is increased by at least 30 '.
2. ioo Teile Kolophonium werden geschmolzen und in die Schmelze unter Rühren 5o Teile des durch Kondensation von Phenoxyessigsäure mit Formaldehyd erhaltenen Harzes eingetragen. Dieser werden noch 12 Teile feingepulverte Kreide zugesetzt und die Temperatur langsam gesteigert, bis sie schließlich 24.o bis 25o' erreicht. -Nachdem eine Probe der Schmelze erst bei i 3o bis i35° zu kleben beginnt, wird erkalten gelassen. Man erhält ein sehr helles, hartes Harz, welches sich zur Herstellung von nicht klebenden Lacken als auch in der elektrotechnischen In--lustrie v envenden läßt.2. 100 parts of rosin are melted and poured into the melt under Stir 50 parts of the obtained by condensation of phenoxyacetic acid with formaldehyde Resin registered. 12 parts of finely powdered chalk are added to this and slowly increased the temperature until it finally reached 24o to 25o '. -After a sample of the melt begins to stick at i 3o to i35 ° let cool. A very light-colored, hard resin is obtained, which is suitable for production of non-adhesive lacquers as well as in the electrotechnical industry leaves.
3. iöoTeile Kolophonium werden wie oben mit 6o Teilen des durch Umsetzung des Konrlensationsproduktes aus technischem Kresol und Paraldehyd mit Chloressigsäure entstandenen Kunstharzes verschmolzen. Bei 13o° beginnt man langsam unter Rühren 8 g gebrannte Magnesia einzutragen. Nachdem alles eingetragen, treibt man.die Tempepeur langsam auf 2¢o bis 26o° und läBt dann erkalten. Man erhält ein helles, hochschmelzendes Harz, das sich ausgezeichnet in der Elektrotechnik verwenden läßt.3. iöo parts of rosin are reacted as above with 6o parts of the of the concentration product from technical cresol and paraldehyde fused with chloroacetic acid formed synthetic resin. You start at 13o ° slowly add 8 g of burnt magnesia while stirring. After everything has been entered, the temperature is slowly increased to 2 ° to 26 ° and then allowed to cool. You get a light-colored, high-melting resin that is excellent in electrical engineering lets use.
