Description
Verfahren zur Darstellung von gehärteten Kunstmassen Es wurde gefunden, daß man zu gehärteten Kunstmassen von vorteilhaften Eigenschaften gelangt, wenn man die durch Umsetzung von Phenolaldehydharzen mit Halogenfettsäuren erhaltenen Harzcarbonsäuren in ihre wasserlöslichen Ammoniumverbindungen überführt und diese mit oder ohne Füllkörper auf Temperaturen über i oo° erhitzt.Process for the preparation of hardened artificial masses It has been found that one arrives at hardened synthetic compositions of advantageous properties if one obtained by reacting phenol aldehyde resins with halogenated fatty acids Resin carboxylic acids converted into their water-soluble ammonium compounds and these heated to temperatures above 100 ° with or without packing.
Die Darstellung der Ammoniumverbindungen erfolgt durch Absättigen der freien Carboxylgruppe mit Ammoniak oder dessen Derivaten, wie Methylamin, zweckmäßig in wäßriger Lösung. Die erhaltene neutrale, klare, wäßrige Lösung läßt sich beliebig verdünnen und konzentrieren. Nach Verdampfen des Wassers und Erhitzen des Lackrückstandes über i oo° - man geht mit der Temperatur zweckmäßig auf 15 o bis i 6o° - erhärtet dieser zu einem vollkommen unschmelzbaren und unlöslichen Körper.The ammonium compounds are prepared by saturating the free carboxyl group with ammonia or its derivatives, such as methylamine, expediently in aqueous solution. The neutral, clear, aqueous solution obtained can be diluted and concentrated as desired. After evaporation of water and heating the paint residue over i oo ° - one goes to the temperature appropriate to 1 5 o to i 6o ° - confirmed this to a completely infusible and insoluble body.
Werden die «#äßrigen Lösungen der Ammoniumsalze dieser carboxyIhaltigen Harze mit Füllstoffen versetzt, wird beispielsweise Papierschlamm mit diesen wäßrigen Lösungen imprägniert und in entsprechende Formen gepreßt, so lassen sich die so gepreßten Formlinge ebenfalls durch Erhitzen zu ganz neuen, bisher noch nicht bekannten Kunststoffen verarbeiten. Auf diese Weise ist es möglich, aus dem billigen, technisch anfallenden Papierschlamm durch Imprägnieren mit diesen vorgenannten Lösungen alle möglichen Formlinge darzustellen, wie z. B. Röhren, Kästchen, Büchsen, Schalen, Fässer, Ferner Gebrauchsgegenstände mannigfacher Art. Diese geformten Massen haben sehr wertvolle Eigenschaften; sie sind vollkommen wasserdicht und außerordentlich widerstandsfähig gegen mechanische wie auch- chemische Beanspruchung. An Stelle von Papiermassen können, sofern es der Verwendungszweck erfordert, auch andere Füllstoffe Verwendung finden, beispielsweise Asbestfasern, Holzmehl, Infusorienerde, Hornpulver usw. Da die in oben gekennzeichneter Weise durch Erhitzen erhaltenen Produkte auch ein sehr geringes Leitvermögen haben, so eignen sie sich auch sehr gut für Isolierzwecke in. der Elektrotechnik.The aqueous solutions of the ammonium salts of these carboxy-containing Resins mixed with fillers, for example, paper sludge is mixed with these aqueous Solutions impregnated and pressed into appropriate shapes, that's how they can be Pressed bricks also by heating to form completely new, hitherto unknown Process plastics. In this way it is possible, from the cheap, technically resulting paper sludge by impregnating with these aforementioned solutions all possible moldings, such as B. tubes, boxes, cans, bowls, Barrels, also utensils of various kinds. These have shaped masses very valuable properties; they are completely waterproof and extraordinary resistant to mechanical as well as chemical stress. Instead of Other fillers can also be used for paper pulps, provided the intended use so requires Find use, for example, asbestos fibers, wood flour, infusor earth, horn powder etc. Since the products obtained by heating in the manner indicated above also have a very low conductivity, so they are also very suitable for insulation purposes in. electrical engineering.
Dadurch, daß es gelungen ist, die härtbaren Phenolaldehydharze in wasserlösliche Form zu bringen, ohne daß man zur Anwendung von fixem Alkali gezwungen ist, welches zur Herstellung einer wasserlöslichen Form der Phanolaldehydharze erforderlich ist, sind der Verwendbarkeit der nach vorliegendem Verfahren gewonnenen Produkte viel größere Gebiete geöffnet als den bisher bekannten härtbaren Harzen.Because it has been possible to use the curable phenol aldehyde resins in Bring water-soluble form without being forced to use fixed alkali is what is required for the preparation of a water-soluble form of the phanolaldehyde resins are the usability of the products obtained according to the present process opened much larger areas than the previously known curable resins.
Beispiel i 2 o Gewichtsteile des durch Einwirkung von 14o Gewichtsteilen Formaldehyd, 30 %, auf i io Gewichtsteile Kresol (technisch) bei Gegenwart von Alkali erhaltenen Kunstharzes werden in 25o Gewichtsteilen konzentrierter Natronlauge (42'B6) und 26o Gewichtsteilen Wasser gelöst. Zur_ klaren, etwas viskosen Lösung werden bei 5o bis 6o° langsam und portionsweise 9o Gewichtsteile Chloressigsäure gegeben. Beim jedesmaligen Eintragen tritt Erwärmung ein; man vermeidet ein überschäumen dadurch, daß man die Temperatur nicht über 8o° steigen läßt, hält aber, nachdem alles eingetragen, die Temperatur noch etwa 2o Minuten bei ioo bis 10z°. Die klare Lösung wird mit kaltem Wasser um das Mehrfache ihres Volumens verdünnt und hierauf die entstandene Harzsäure durch Zugabe von Salzsäure bis zur sauren Reaktion ausgefällt. Durch Auswaschen wird diese von anorganischen Bestandteilen, NaCl, befreit. Die noch feuchte Paste wird jetzt in eine Lösung von wäßrigem Ammoniak bei mäßig erhöhter Temperatur (6o bis 65°) eingetragen. Die Ammoniakmenge beträgt den der Harzsäure aliquoten Teil, d. h. etwa 17 Gewichtsteile ioo % Ammoniak. Es genügt aber schon weniger, um eine klare Lösung zu erhalten. Die Lösung kann direkt als solche verwendet werden; man kann sie aber auch je nach Bedarf konzentrieren oder verdünnen. Sie kann verwendet werden zum Imprägnieren von Gewebe, zur Herstellung von Lacken, da sie sich gut auf Flächen auftragen läßt und auf ihnen zu einem glatten, glänzenden Film auftrocknet, der nach Erhitzen auf etwa i 5o° unschmelzbar und unlöslich wird. Um das Produkt im wasserfreien, festen Zustande herzustellen, genügt es, es einzudampfen, was man, um ein überhitzen zu vermeiden, zweckmäßig im Vakuum vornimmt. Das wasserfreie Produkt stellt ein trockenes Pulver dar, das gleichfalls beim Erhitzen über ioo° unlöslich und unschmelzbar wird unter Abgabe von Ammoniak und etwas Kondensationswasser. Es löst sich leicht in Wasser und hat vor dem als Phenolformaldehydkunstharz bekannten Kunstharz den Vorzug, daß man zur Herstellung von Lösungen das teure organische Lösungsmittel sparen kann.Example i 20 parts by weight of the synthetic resin obtained by the action of 14o parts by weight formaldehyde, 30%, to io parts by weight cresol (technical) in the presence of alkali are dissolved in 250 parts by weight of concentrated sodium hydroxide solution (42'B6) and 26o parts by weight of water. To _ clear, slightly viscous solution are added in portions 9o parts by weight of chlorine acetic acid at 5o to 6o ° slowly. Every time you enter, warming occurs; One avoids foaming over by not letting the temperature rise above 80 °, but after everything has been entered, the temperature is maintained at 100 to 10z ° for about 20 minutes. The clear solution is diluted several times its volume with cold water and the resin acid formed is then precipitated by adding hydrochloric acid until it becomes acidic. This is freed from inorganic constituents, NaCl, by washing out. The still moist paste is now added to a solution of aqueous ammonia at a moderately elevated temperature (60 to 65 °). The amount of ammonia is that of the resin acid aliquot, ie about 17 parts by weight of 100% ammonia. But it is less enough to get a clear solution. The solution can be used directly as such; however, they can also be concentrated or diluted as required. It can be used for the impregnation of fabric, for the production of lacquers, since it can be easily applied to surfaces and dries on them to form a smooth, glossy film, which becomes infusible and insoluble after heating to about 150 °. In order to produce the product in an anhydrous, solid state, it is sufficient to evaporate it, which is expediently carried out in a vacuum to avoid overheating. The anhydrous product is a dry powder, which also becomes insoluble and infusible when heated to over 100 °, releasing ammonia and some water of condensation. It dissolves easily in water and has the advantage over the synthetic resin known as phenol-formaldehyde synthetic resin that one can save the expensive organic solvent for the preparation of solutions.
