Description
Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Harzleimung von Fasersuspensionen mit Hilfe von unverstärkten oder verstärkten Harzen und Fixiermitteln auf Basis von Aluminiumsalzen. Die Harzleimung führt zu einer Hydrophobierung der Fasern und damit des Papiers. Als Aluminiumsalze für die Harzleimung kommen vor allem Aluminiumsulfat oder Polyaluminiumhydroxychlorid in Frage, wobei in zunehmendem Maße Gemische von Harzen und Fixiermitteln zur Anwendung kommen. Besonders bewährt haben sich Produkte der Anmelderin auf Basis von Harzen und Polyaluminiumhydroxychlorid, die unter der Bezeichnung "Kentosol" vertrieben werden.object The present invention is a process for resin sizing of Fiber suspensions with the aid of unreinforced or reinforced resins and fixing agents based on aluminum salts. The resin sizing leads to a hydrophobization of the fibers and thus of the paper. As aluminum salts for the resin sizing are mainly aluminum sulfate or polyaluminum hydroxychloride in question, whereby increasingly mixtures of resins and Fixing agents are used. Have proven especially Applicant's products based on resins and polyaluminum hydroxychloride, which are sold under the name "Kentosol".
Da bei der Herstellung von Papier in zunehmendem Maße Papier recycelt wird, welches durch verschiedene Inhaltsstoffe oder auch Druckfarben etc. verunreinigt ist, wird durch diese Verunreinigungen der Vorgang der Hydrophobierung, der nachfolgend vereinfacht Harzleimung genannt wird, mehr oder weniger gestört.There paper is increasingly being recycled in the manufacture of paper which contaminated by various ingredients or printing inks, etc. is, by these impurities the process of hydrophobing, which in the following is simply called resin sizing, more or less disturbed.
Die Erfindung hat sich somit die Aufgabe gestellt, diese Störungen zu minimieren und die Harzleimung von Faserstoffsuspensionen sicher und zuverlässig durchzuführen unabhängig davon, ob überhaupt und unabhängig davon, welche Verunreinigungen in welchen Mengen in der Faserstoffsuspension vorhanden sind.The Invention has thus set itself the task of these disorders minimize and resin sizing of pulp suspensions safely and reliable perform independently of it, if anything and independent of which impurities are present in which quantities in the pulp suspension are.
Diese Aufgabe kann überraschenderweise in der Weise gelöst werden, dass zusätzlich fluorhaltige Fixierhilfsmittel verwendet werden, nämlich Fluorkieselsäure und/oder deren Salze sowie Fluorsulfonsäure und/oder deren Salze.These Task can be surprising solved in the way be that extra fluorine-containing fixing aids are used, namely fluorosilicic acid and / or their salts and fluorosulfonic acid and / or their salts.
Diese fluorhaltigen Fixierhilfsmittel werden entweder unmittelbar vor oder nach der Zugabe des Fixiermittels zugesetzt. Sie können aber auch schon zuvor entweder dem Fixiermittel oder aber einem Leimungsmittel zugesetzt werden, wobei dieses bereits das Harz und das aluminiumhaltige Fixiermittel enthält.These fluorine-containing fixatives are either immediately before or added after the addition of the fixing agent. But you can even before either the fixative or a sizing agent be added, this already the resin and the aluminum-containing Contains fixative.
Das Verfahren ist somit sehr flexibel und kann den jeweiligen Bedürfnissen und den jeweiligen Produktionsverfahren leicht angepasst werden.The Procedure is thus very flexible and can meet the respective needs and easily adapted to the respective production process.
Dieses Ergebnis war nicht vorhersehbar und kann gegebenenfalls nachträglich damit erklärt werden, dass die fluorhaltigen Fixierhilfsmittel die aufgrund des geringen Radius und der hohen Ladung stark polarisierende Wirkung des fixierenden Aluminiumions oder seiner Komplexe wirkungsvoll unterstützen. Diese stark polarisierende Wirkung ist ursächlich für das Zustandekommen der Verbindung zwischen Harz, Aluminium und Faser. Die fluorhaltigen Fixierhilfsmittel besitzen eine hohe negative Ladungsdichte am Fluoratom und sind damit anscheinend in der Lage, die Wechselwirkungen zwischen Harz, Aluminium und Faser zu verstärken und damit die die Anlagerung des Harzes an die Faserstoffe in der Suspension. Die die Leimung nachteilhaft beeinflussenden Wechselwirkungen zwischen dem Leimungssystem und Verunreinigungen, wie sie insbesondere beim Recycling von Papier entstehen, werden wirkungsvoll reduziert, da die Affinität der fluorhaltigen Fixierhilfsmittel zum Aluminium größer ist, als die Affinität besagter Störstoffe. Die Menge an fluorhaltigen Fixierhilfsmittel kann zwar variiert werden, liegt aber vorzugsweise im Bereich zwischen 3 und 5 Gew.-% bezogen auf das Leimungsmittel und etwa 20 Gew.-% bezogen auf das Fixiermittel. Bezogen auf die Stoffsuspension beträgt die Menge an fluorhaltigen Fixiermittel etwa 0,5 Gew.-%. Die Menge an fluorhaltigem Fixierhilfsmittel kann aber im Einzelfall höher oder niedriger gewählt werden, und zwar in Abhängigkeit von Art und Menge der störenden Verunreinigungen. Dies wiederum hängt in erheblichem Maße von Art und Menge des recycelten Papiers ab.This Result was unpredictable and may be subsequently with it explained be that the fluorine-containing fixing aids due to the low radius and high charge strongly polarizing effect of fixing aluminum ion or its complexes effectively support. This strongly polarizing effect is the cause of the connection between Resin, aluminum and fiber. The fluorine-containing fixatives have a high negative charge density on the fluorine atom and are therefore apparent capable of the interactions between resin, aluminum and fiber to reinforce and thus the addition of the resin to the fibers in the Suspension. The sizing disadvantageous influencing interactions between the sizing system and impurities, as they in particular when recycling paper, are effectively reduced, because the affinity the fluorine-containing fixing aid to aluminum is greater than the affinity said impurities. The amount of fluorochemical fixative may vary but is preferably in the range between 3 and 5% by weight. based on the sizing agent and about 20 wt .-% based on the fixing agent. Related to the stock suspension is the amount of fluorochemical fixer is about 0.5% by weight. The amount at fluorine-containing fixative but may be higher or higher in individual cases chosen lower be, depending on of type and amount of disturbing Impurities. This in turn depends to a considerable degree on art and amount of recycled paper.
Gegenstand der vorliegenden Erfindung sind somit zunächst das Verfahren zur Harzleimung gemäß den Verfahrensansprüchen 1 bis 3 sowie weiterhin die Mittel zur Durchführung des Verfahrens gemäß Ansprüchen 4 und 5.object The present invention thus initially relates to the process for resin sizing according to the method claims 1 to 3 and furthermore the means for carrying out the method according to claims 4 and 5th
Das erfindungsgemäße Verfahren wird durch die nachfolgenden Beispiele näher erläutert.The inventive method is explained in more detail by the following examples.
Beispiel 1example 1
Zum Vergleich wurde jeweils mit und ohne Zusatz von Fluorkieselsäure gearbeitet und nach der Leimung der Cobb-Wert gemessen. Der Cobb-Wert zeigt die Wasseraufnahmefähigkeit in einem bestimmten Zeitraum als Indiz für die Qualität der Hydrophobierung. Je niedriger der Cobb-Wert ist, umso besser ist die Leimung. Als Faserstoffsuspension mit hohem Störstoffanteil wurde deinktes Altpapier eingesetzt. Es wurde 5% des kombinierten Leimungsmittels Kentosol APNV eingesetzt. Die Cobb(60)-Bestimmung ergab 45/45. Erfindungsgemäß wurden 4% der Salzsäure in dem Produkt Kentosol AP NV durch Fluorkieselsäure ersetzt. Unter gleichen Bedingungen wurde ein Cobb(60)-Wert von 31/30 erzielt.To the Comparison was carried out in each case with and without the addition of fluorosilicic acid and measured after sizing the Cobb value. The Cobb value shows the water absorption capacity in a certain period of time as an indication of the quality of the water repellent treatment. The lower the Cobb value, the better the sizing. When Pulp suspension with high impurity content was deinked Waste paper used. It became 5% of the combined sizing agent Kentosol APNV used. The Cobb (60) determination gave 45/45. According to the invention, 4% hydrochloric acid in the product Kentosol AP NV replaced by fluorosilicic acid. Under same Conditions, a Cobb (60) score of 31/30 was achieved.
