Description

Verfahren zur Papierleimung Die vorliegende Erfindung betrifft ein Verfahren zur Papierleimung.Paper Sizing Process The present invention relates to a Process for paper sizing.

Für die Zwecke der Papierleimung werden vorteilhaft Harzseifen verwendet, die einen kleineren oder größeren Anteil des benutzten Harzes uriverseift als sog. Freiharz enthalten. Der nicht verseifte Harzanteil neigt aber dazu, sich abzuscheiden oder erreicht nicht die erforderliche feine Verteilung (Dispersitätsgrad). Um letzterem Übelstand abzuhelfen, hat man bereits vorgeschlagen, die Herstellung solcher freiharzhaltigen Seifen oder Emulsionen unter Verwendung besonderer Dispergierungsvorrichtungen, wie Rührwerke, Injektoren, Strahldüsen, Homogenisatoren o. dgl., vorzunehmen.Resin soaps are advantageously used for paper sizing purposes, which ureans a smaller or larger proportion of the resin used than so-called. Free resin included. However, the unsaponified resin content tends to separate out or does not achieve the required fine distribution (degree of dispersion). To the latter To remedy the problem, it has already been proposed to manufacture such resin-free Soaps or emulsions using special dispersing devices, such as agitators, injectors, jet nozzles, homogenizers or the like.

Zur Stabilisierung der so hergestellten unbeständig en Dispersionen und Emulsionen hat man schon den Zusatz sog. Schutzkolloide, wie beispielsweise Leim, Casein, Stärke, Wasserglas, Carragheenmoos und anderer Körper mit kolloiden Eigenschaften, in Vorschlag gebracht. Durch die Beigabe solcher Körper wurde aber die Dispergierung und Emulgierung erschwert, ohne daß die Qualität des erzielten Papiers wesentlich verbessert wurde.To stabilize the unstable dispersions produced in this way and emulsions you already have the addition of so-called protective colloids, such as Glue, casein, starch, water glass, carragheen moss and other bodies with colloids Properties, brought in proposal. However, by adding such bodies the dispersion and emulsification made more difficult without affecting the quality of the achieved Paper has been significantly improved.

Erfindungsgemäß wird nun das Verfahren so durchgeführt, daß die Leimurig mit an such bekannten freiharzhaltigen Harzemulsionen in Gegenwart von Alkylaminen vorgenommen wird, bei denen mindestens eine Alkylgruppe eine OH-Gruppe trägt.According to the invention, the method is now carried out so that the Leimurig with known free resin-containing resin emulsions in the presence of alkylamines is made in which at least one alkyl group carries an OH group.

Als besonders günstig für den vorliegenden Zweck haben sieh das Mono-, Di- und Trioxäthylamin bewährt, die folgende Formeln aufweisen NH2 CH2-CH2-OH, NH (CH2-CH2-OH)2, N (CH2 CH2-OH)3, sowie die homologen Oxäthylalkylamine. Man hat Triäthanolamin und andere Äthanolamine bzw. ihre Seifen bereits Als Emulgermittel für Wachs- und öleinulsionen vorgeschlagen. Im vorliegenden Falle ist es aber nicht die Emulgierwirkung der erfindungsgemäß verwendeten Amine, die die beobachtete erheblich bessere Leimung des Papiers bedingt, denen Versuche haben ergeben, daß je nach den angewendeten Verfahrensmaßnahmen bzW. Apparaturen die Leimung in Gegenwart der genannten Amine ebenso gute Ergebnisse zeitigt, wenn der Dispersionsgrad an such schlechter ist.The mono, Di- and trioxethylamine proven, the following formulas have NH2 CH2-CH2-OH, NH (CH2-CH2-OH) 2, N (CH2 CH2-OH) 3, as well as the homologous oxethylalkylamines. You have triethanolamine and other ethanolamines or their soaps already as emulsifiers for wax and suggested oil emulsions. In the present case, however, it is not the emulsifying effect of the amines used according to the invention, which considerably increases the observed effect Better sizing of the paper due to which tests have shown that depending on the applied procedural measures or Apparatuses the sizing in the presence of the said Amine produces equally good results when the degree of dispersion is poor is.

Die erfindungsgemäß hergestellten Papiere zeigen eine erheblich geringere Durchlässigkeit bzw. eine wesentlich bessere Leimung als Papiere, die nach dem üblichen Verfahren ohne die erfindungsgemäßen Zusätze hergestellt wurden.The papers produced according to the invention show a considerably lower level Permeability or a much better sizing than papers, which after the usual Process without the additives according to the invention were produced.

Das Harz in den Seifen oder Emulsionen kann teilweise durch Fettsäuren, Wachse, Montanwachse, Paraffin, Ceresin, Teer oder durch Gemische dieser Stoffe ersetzt werden. Ausführungsbeispiele I. 450l weiches Wasser, 665 kg Harz (Kolophonium), 32kg Atznatron fest, 44g Trioxäthylamin in 4ol Wasser werden unter starkem Rühren etwa 3 Stunden verseift. Die hergestellte Harzseihe enthält etwa 6o% Frei-2. 45ol weiches Wasser, 5oo kg Harz (Kölophonium), I6o kg Montanwachs, 5 o kg Ätznatron fest, Ekg Trioxäthylamin in 6öl Wasser.The resin in the soaps or emulsions can be partly replaced by fatty acids, Waxes, montan waxes, paraffin, ceresin, tar or mixtures of these substances be replaced. Embodiments I. 450l soft water, 665 kg resin (rosin), 32kg of caustic soda solid, 44g of trioxethylamine in 4ol of water are stirred vigorously saponified for about 3 hours. The resin series produced contains about 60% free-2. 45ol soft water, 500 kg of resin (Kölophonium), 160 kg of montan wax, 50 kg of caustic soda solid, Ekg trioxethylamine in 6oil water.
