Description
Verfahren zum Herstellen von Druckfarben unter Verwendung von Sulfitcelluloseablauge Zusatz zum Patent 542 587 Die Erfindung betrifft ein Verfahren zur Herstellung einer Druckfarbe für Zeitungs-, Buch- und Illustrationsdruck gemäß Patent 542587. Process for the production of printing inks using sulphite cellulose waste liquor.
Gegenstand des Hauptpatents ist ein; Verfahren zur Herstellung einer Druckfarbe auf der Basis von Sulfitcelluloseablauge, bei der die schädigende Wirkung der sauren Eigenschaften der Ablauge sowie die von Bestandteilen derselben, wie Kalk, Eisen, Gerbstoffen usw., durch Abstumpfung der Säure und durch Unschädlichmachung dieser Bestandteile durch Beigabe verhältnismäßig geringer Mengen von 01- und Fettseifen o. dgl. beseitigt werden soll.The subject of the main patent is a; Process for the production of a printing ink on the basis of sulphite cellulose waste liquor, in which the damaging effect of the acidic properties of the waste liquor and that of its constituents, such as lime, iron, tannins, etc., by dulling the acid and rendering these components harmless by adding relatively small amounts of oil and fatty soaps or the like should be eliminated.
Die vorliegende Erfindung beruht auf der Erkenntnis, daß einmal die Abstumpfung der Säuren besonders vorteilhaft mittels Ammoniaks gestaltet werden kann, daß weiter die Unschädlichmachung von Kalk, Eisen, Gerbstoffen durch Beigabe besonders hergestellter Seifen und schließlich auch die Emulgierung der neutralisierten und mit Seife behandelten Sulfitcelluloseablauge durch ein bestimmtes Emulgierungsmittel gefördert werden kann.The present invention is based on the finding that once the The acids are blunted particularly advantageously by means of ammonia can that further the rendering harmless of lime, iron, tannins by adding them specially manufactured soaps and finally also the emulsification of the neutralized ones and soap-treated sulphite cellulose waste liquor by a certain emulsifying agent can be promoted.
Die Abstumpfung der Säuren erfolgt mit Ammoniak, und zwar deswegen, weil Alkalien oder Erdalkalien noch durch Bildung von Harzseifen eine Gerinnung und Ausfällung der Salze der Ablauge bewirken, die auf den Gelatinewalzen sitzenbleiben und sie zerreißen können.The acids are blunted with ammonia, namely, because alkalis or alkaline earths still coagulate due to the formation of resin soaps and cause precipitation of the salts of the waste liquor which remain on the gelatin rollers and they can tear apart.
Die Abstumpfung der Säuren kann mit Ammoniakmengen erfolgen, die theoretisch zu .einer völligen Neutralisation des festgestellten Säuregrades nicht ausreichen, weil die Ionisation des Ammoniaks hinreicht, der fertiggestellten Farbe gleichwohl einen neutralen Charakter zu verleihen. Die Seife, die zur Unschädlichmachung der schädigenden Kalk-, Eisen-, Gerbstoffbestandteile usw. der Sulfitcelluloseablauge dient, soll erfindungs. gemäß möglichst keine Oxygruppen enthalten, um Polymerisation unter Bindung der Schwermetalle usw. und somit eine Gerinnung zu vermeiden.The acids can be blunted with amounts of ammonia, which theoretically not sufficient for a complete neutralization of the determined degree of acidity, because the ionization of the ammonia is sufficient, the finished paint is sufficient to give it a neutral character. The soap used to render the damaging lime, iron, tannin components etc. of the sulphite cellulose waste liquor serves, should fiction. as possible to contain no oxy groups in order to polymerization by binding the heavy metals etc. and thus avoiding coagulation.
Z. B. kann man sich erfindungsgemäß einer Seife bedienen, die unter Verwendung von Holzöl, einem ungesättigten Kohlenwasserstoff ohne OH-Gruppen, hergestellt ist. Weiter kommen in Betracht z. B. Rapsöl und S oyaöl.For example, according to the invention, a soap can be used which is described under Using wood oil, an unsaturated hydrocarbon without OH groups is. Next come into consideration z. B. rapeseed oil and s oya oil.
Eine Seife der hier in Betracht kommenden Art stellt man in der Weise her, daß man Holzöl mit einem methylierten cyclischen Kohlenwasserstoff, wie Toluol, Xylol usw., unter Zusatz von Alkohol, Aceton und sonstigen Reduktionsmitteln etwa 24 Stunden bei einer Temperatur von 4o bis 5o° behandelt. Das erhaltene Produkt wird mit alkoholischer Kalilauge verseift, wobei dafür Sorge getragen werden muß,, daß . das Reduktionsmittel im Endprodukt in genügender Menge vorhanden ist (1/2 oder 1/4 der Gesamtmenge des Lösungs- bzw. Verseifungsmittels).A soap of the kind under consideration here is put in this way made that wood oil with a methylated cyclic hydrocarbon, such as toluene, Xylene, etc., with the addition of alcohol, acetone and other reducing agents, for example Treated for 24 hours at a temperature of 4o to 5o °. That received The product is saponified with alcoholic caustic potash solution, which is taken care of must ,, that. the reducing agent is present in sufficient quantity in the end product (1/2 or 1/4 of the total amount of solvent or saponifying agent).
Die so gewonnene Seife wird der Sulfitcelluloseablauge in geringen Mengen zugegeben, so zwar, daB die in der Sulfitablauge enthaltenen Kalk-, Eisen- und Gerbstoffmengen vollkommen neutralisiert und gebunden werden.The soap obtained in this way becomes the sulphite cellulose waste liquor in small amounts Quantities added, so that the lime, iron and amounts of tannin are completely neutralized and bound.
Um die in der beschriebenen Weise behandelte SÜlfitcelluloseablauge mit dem Mineralöl zu emulgieren, bedient man sich erfindungsgemäß eines Emulgierungsmittels, das aus besonders stickstoffreichen Eiweißsäuren (höhere Polypeptiden), unter Zusatz von Traganth gelöst, besteht. In Betracht kommen alle Eiweißsäuren, soweit sie den Charakter bzw. die Reaktion des Eiweißes behalten haben, ohne zu gerinnen (Albumosen), z. B. auch die Nukleinsäuren des Kaseins.To the sulphate cellulose waste liquor treated in the manner described to emulsify with the mineral oil, an emulsifying agent is used according to the invention, that from particularly nitrogen-rich protein acids (higher polypeptides), with added detached from tragacanth exists. All protein acids come into consideration, insofar as they are Have retained the character or the reaction of the protein without clotting (albumoses), z. B. also the nucleic acids of casein.
Es hat sich herausgestellt, daß hierdurch das Mineralöl mit der Sulfitcelluloseablauge in- eine innige Emulsion übergeführt wird, die annähernd konstant bleibt.It has been found that this results in the mineral oil with the sulphite cellulose waste liquor is converted into an intimate emulsion, which remains almost constant.
Beispiel Etwa 3o kg Sulfitablauge vom spezifischen Gewicht 1,32 bis 438 werden mit Ammonick nicht vollkommen neutralisiert und mit 5 % Wasser verdünnt. Hierzu werden r,2 kg der beschriebenen, nicht schäumenden Seife sowie 25o g Emulgierungsmittel zugegeben, sodann etwa ¢o kg Mineralöl und bis zur vollständigen Emulgierung verrührt.Example About 30 kg of sulphite waste liquor with a specific gravity of 1.32 to 438 are not completely neutralized with Ammonick and diluted with 5% water. To this end, about 2 kg of the non-foaming soap described and 250 g of emulsifying agent are added, then about ¢ o kg of mineral oil and stirred until emulsification is complete.
Danach erfolgen Zusätze von Ruß, Leinöl, Glycerin und Teerblau in üblichen: Mengen, worauf die ganze Masse gründlich ver. rührt wird.Then add carbon black, linseed oil, glycerine and tar blue in usual: quantities, after which the whole mass is thoroughly stirred.
