Description
Die Erfindung betrifft den in den Patentansprüchen beschriebenen Papierleim für die Masseleimung und Oberflächenleimung.The invention relates to the paper glue described in the claims for Bulk sizing and surface sizing.
Die Innenleimung von Papier mit Kolophoniumharz und mit verstärktem Kolophoniumharz wurde von Casey in Pulp and Paper, 2. Auflage, Band II: Papermaking, Kapitel XIII, Seiten 1043-1066, beschrieben. Verstärkte Kolophoniumharze können durch Umsetzen von Maleinsäureanhydrid oder anderen dienophilen Verbindungen mit Kolophonium unter Erhöhung der Zahl der Carbonsäuregruppen hergestellt werden. Ein typischer verstärkter Leim kann etwa 1 bis 30% Maleopimarsäurenanhydrid enthalten.The inside sizing of paper with rosin and with reinforced rosin was by Casey in Pulp and Paper, 2nd edition, Volume II: Papermaking, Chapter XIII, pages 1043-1066. Reinforced rosins can be made by reacting Maleic anhydride or other dienophilic compounds with rosin while increasing the number of carboxylic acid groups. A typical reinforced glue can contain about 1 to 30% maleopimaric anhydride.
Es wird allgemein anerkannt, dass ein Leim mit hohem Anteil an freiem Kolophoniumharz zu einer besseren Leimung führt und weniger Alaun erfordert. Dabei ist es durch Verwendung eines Schutzkolloids möglich, einen hochstabilen Leim herzustellen, der bis zu 90% freies Kolophonium enthält. Nach dem Bewoid-Verfahren (Sandermann - Naturharze, Terpentinöl, Tallöl S. 205 Springer-Verlag 1960 ) wird ein Leim mit hohem Anteil an freiem Kolophonium hergestellt, der etwa 90% freies, in einer kleinen Menge Kolophoniumseife dispergiertes und durch die Anwesenheit von etwa 2% Casein oder eines anderen Protein stabilisiertes Kolophonium enthält. Das Casein wird als Schutzkolloid eingesetzt, um das Wachstum von Kolophoniumteilchen zu verhindern, wodurch sie in feinem Zerteilungszustand gehalten werden. Beim Bewoid-Verfahren wird das Kolophonium in Gegenwart von 1 bis 2% Natriumhydroxid und etwa 2% Casein mechanisch zerteilt. Das Kolophoniumharz wird erhitzt und mechanischen Scherspannungen ausgesetzt, bis es in kleine Teilchen unterteilt ist. Eine kleine Menge Ätznatron wird dann dem geschmolzenen Kolophonium zugesetzt, um es teilweise zu verseifen und dann wird Casein zur Stabilisierung des dispergierten Kolophonium zugesetzt. Das gelöste Casein wird unter kräftigem Rühren in das geschmolzene Kolophoniumharz eingearbeitet, worauf eine zusätzliche Menge NaOH zugesetzt wird oder die heisse Kolophoniumschmelze wird in Casein enthaltendes Wasser gespritzt. Schliesslich wird Wasser zugesetzt, um eine fertige Dispersion mit etwa 30 - 45% Festanteilen zu ergeben, die in dieser Form verwendet wird. Dieses Verfahren wird auch als "Inversionsverfahren zur Herstellung von Kolophoniumharzleim" und der so hergestellte Kolophoniumharzleim als "Invertleim" bezeichnet.It is generally accepted that a glue with a high proportion of free rosin too leads to better sizing and requires less alum. It is through use of a protective colloid possible to produce a highly stable glue that is up to 90% free Contains rosin. According to the Bewoid process (Sandermann - natural resins, turpentine oil, Tallöl p. 205 Springer-Verlag 1960) becomes a glue with a high proportion of free rosin made about 90% free, dispersed in a small amount of rosin soap and stabilized by the presence of about 2% casein or other protein Contains rosin. The casein is used as a protective colloid to prevent the growth of Prevent rosin particles, keeping them in a fine state of disintegration will. In the Bewoid process, the rosin is in the presence of 1 to 2% Sodium hydroxide and about 2% casein mechanically broken down. The rosin is heated and subjected to mechanical shear stresses until it is divided into small particles. A small amount of caustic soda is then added to the melted rosin to make it partially saponified and then casein is used to stabilize the dispersed Rosin added. The dissolved casein is mixed into the melted one with vigorous stirring Rosin incorporated, after which an additional amount of NaOH is added or the hot rosin melt is injected into water containing casein. Eventually Water was added to give a finished dispersion with about 30-45% solids, which is used in this form. This process is also called "inversion process Production of rosin glue "and the rosin glue thus produced as Designated "invert glue".
Unter Anwendung des Inversionsverfahrens wurde nach der US-PS 23 93 179 ein Leim mit freiem Kolophoniumharz hergestellt, wobei anstelle von Natriumhydroxid ein nicht alkalisches Dispersionsmittel, z.B. ein sulfonierter höherer Fettalkohol, verwendet wurde. Das Kolophonium wurde geschmolzen, und die gewünschte Menge Dispersionsmittel wurde unter zur Bildung einer homogenen geschmolzenen Masse ausreichendem Rühren zugesetzt. Dann wurde nach und nach unter raschem Rühren eine praktisch neutrale oder schwach saure wässrige Lösung oder Dispersion eines Schutzkolloids, z.B. Casein, zugesetzt, wodurch sich eine pastenähnliche Dispersion mit hohem Feststoffanteil bildete, die dann mit Wasser auf einen Feststoffgehalt von 40 bis 60 Gew.-% verdünnt wurde.Using the inversion process was a glue with free according to US-PS 23 93 179 Rosin made using a non-alkaline instead of sodium hydroxide Dispersing agents, e.g. a sulfonated higher fatty alcohol was used. The Rosin was melted and the desired amount of dispersant was added to Sufficient stirring was added to form a homogeneous molten mass. Then was gradually with rapid stirring a practically neutral or weakly acidic aqueous Solution or dispersion of a protective colloid, e.g. Casein added, which results in a paste-like dispersion with high solids content, which then with water on a Solids content of 40 to 60 wt .-% was diluted.
In dem Prosize-Verfahren (Sandermann - Naturharze, Terpentinöl, Tallöl S. 205 Springer-Verlag 1960 ) zur Herstellung eines geschützten Leims mit einem hohen Anteil an freiem Kolophoniumharz wurden durch die Gegenwart eines grenzflächenaktiven Proteins, z.B. Sojabohnen-Protein, die Kolophoniumteilchen am Wachsen zu grösseren Aggregaten gehindert.In the Prosize process (Sandermann - natural resins, turpentine oil, tall oil p. 205 Springer-Verlag 1960) for the production of a protected glue with a high proportion of Free rosin was removed by the presence of a surfactant protein, e.g. Soybean protein that prevents the rosin particles from growing into larger aggregates.
Nach der DE-PS 11 31 348 waren die verstärkten Kolophoniumharze bisher nicht zur Herstellung von Dispersionen geeignet, da sie meistens zu hohe Schmelzpunkte besassen, zur Kristallisierung neigten oder beim Dispergieren feine Krusten bildeten, die zu Sedimentationserscheinungen führten. Das Patent beschreibt einen Papierleim und ein Verfahren zu dessen Herstellung in Form einer wässrigen Dispersion mit einem hohen Gehalt an freiem Kolophoniumharz, bei dem verstärktes Kolophoniumharz bei erhöhten Temperaturen mit Fettsäuren, Fettsäuregemischen und/oder Naphtensäuren gemischt und die Dispersion in bekannter Weise durchgeführt wurde. Das Verfahren wurde als Inversionsverfahren angewandt.According to DE-PS 11 31 348, the reinforced rosins have not previously been used Production of dispersions suitable, since they mostly had too high melting points, for Crystallization tended to form or formed fine crusts when dispersed Sedimentation symptoms led. The patent describes a paper glue and a Process for its preparation in the form of an aqueous dispersion with a high content free rosin, in the reinforced rosin at elevated temperatures mixed with fatty acids, fatty acid mixtures and / or naphthenic acids and the dispersion in was carried out in a known manner. The method was used as an inversion method.

Als anionische Dispergiermittel wurden Materialien auf der Grundlage verseiften Kolophoniums, Natrium-alkylbenzosulfonat, Natrium-naphtalinsulfonsäure, Natrium-laurylsulfat oder das Ammoniumsalz des Sulfatesters eines Akylphenoxy(poletylenoxy)-ethanols eingesetzt.DE-OS 24 26 038 discloses a method for producing a practically stable aqueous dispersion for use in sizing cellulosic fibers Paper production of suitable rosin-based material, whereby an unstable, aqueous dispersion containing at least 5% solids consisting of 0 to 95% rosin and 100 to 5% of a reaction product of rosin with an acid, the rest -C = C-C = O containing ent, the amount of bound as an adduct acidic compound was about 1 to 20% of the total solid weight under a pressure of about 142 to 563 bar and at a temperature of 150 to 190 ° C in the presence of a anionic dispersant was homogenized.

Die schwedische Patentanmeldung 74 10 018-1 beschreibt eine praktisch stabile, wässrige Dispersion, die im wesentlichen aus Wasser, Kolophoniummaterial und als Stabilisator für das Kolophoniummaterial einem Alkaimetall-alkylbenzolsulfonat bestand. Die Dispersionen wurden hergestellt, indem man ein vorbereitetes Gemisch der Komponenten durch einen Homogenisator führte.Swedish patent application 74 10 018-1 describes a practically stable, aqueous Dispersion consisting essentially of water, rosin material and as a stabilizer for the rosin material was an alkali metal alkyl benzene sulfonate. The dispersions were prepared by passing a prepared mixture of the components through a Homogenizer led.

Casein und eine flüchtige Base, z.B. Ammoniak, enthielt, wobei wenigstens 90% des verstärkten Kolophoniumharzes unverseift waren. Zur Herstellung dieses Mittels wurde das Inversionsverfahren angewandt, wobei zunächst verstärktes Kolophonium in einem mit Rühr- und Heizeinrichtung ausgestatteten Behälter geschmolzen wurde. Dann wurde in einem anderen Behälter ein Dispergier- und Stabilisiermittel hergestellt, indem man eine abgemessene Menge eines Schutzkolloids, z.B. Casein, und eine abgemessene Menge einer flüchtigen Base, z.B. Ammoniak, in Wasser löste. Anschliessend wurde dem geschmolzenen Kolophonium rasch das zubereitete Dispergier-und Stabilisiermittel zugesetzt, wobei während und nach der Zugabe Hochgeschwindigkeitsrühren oder ein anderes intensives Durchmischen zur Anwendung gelangte. Schliesslich wurde der Feststoffgehalt der anfallenden wässrigen Kolophoniumdispersion durch Zugabe einer berechneten Menge an Wasser eingestellt.US-PS 39 06 142 discloses a means for gluing paper without using Aluminum sulfate, which is a stable aqueous dispersion of one by reaction with a alpha, beta-unsaturated carboxylic acid or an appropriate anhydride enhanced Rosin, a protective colloid, e.g. Casein and a volatile base, e.g. Ammonia, contained, with at least 90% of the reinforced rosin unsaponified. For To produce this agent, the inversion process was used, initially Reinforced rosin in a container equipped with a stirring and heating device was melted. Then a dispersing and Stabilizer made by using a measured amount of a protective colloid, e.g. Casein, and a measured amount of a volatile base, e.g. Ammonia, dissolved in water. The molten rosin was then quickly dispersed and Stabilizer added, with high speed stirring during and after the addition or other intensive mixing was used. Finally the Solids content of the resulting rosin dispersion by adding a calculated amount of water set.

Die vorstehend beschriebenen Leimungsmittel wurden in einem pH-Bereich von 4,5 - 6 eingesetzt und erforderten zur Fixierung auf der Faser verhältnismässig hohe Mengen Aluminiumsulfat, durch die das Abwasser belastet wird.The sizing agents described above were in a pH range of 4.5-6 used and required relatively high amounts for fixation on the fiber Aluminum sulfate, which pollutes the wastewater.
Eine Verbesserung hinsichtlich des pH-Wertes ist in der Patentschrift EP 0 259 671 beschrieben. Auch dieses Produkt stellt einen Invertleim dar. Ein Produkt ohne Schutzkolloid auf Harzbasis ist bisher für die Leimung im Neutralbereich nicht beschrieben.An improvement with regard to the pH value is in the patent specification EP 0 259 671 described. This product also represents an invert glue. A product without Protective colloid based on resin has so far not been used for sizing in the neutral range described.
Die EPS 0200002 beschreibt ein Verfahren zur Neutralleimung mit einem Einkomponenten-Produkt, das Polyaluminiumchlorid und einen Invertleim enthält. Diese Produkte sind nicht lange lagerfähig, da sie sehr thixotrop sind und deshalb ständig gerührt werden sollen. Ein weiterer Nachteil dieser Produkte ist die geringe Harzmenge, d.h. es wird viel Wasser transportiert und die Einsatzmengen sind sehr hoch - ca. 10 % gegenüber 3 % bei bisher bekannten Leimungsmitteln.The EPS 0200002 describes a process for neutral sizing with a One-component product that contains polyaluminium chloride and an invert glue. This Products cannot be stored for a long time because they are very thixotropic and therefore permanent should be stirred. Another disadvantage of these products is the small amount of resin, i.e. a lot of water is transported and the amounts used are very high - approx. 10% compared to 3% with previously known sizing agents.
Alle Leimungsmittel, die ein Schutzkolloid enthalten, sind metastabile Zubereitungen, die
nur eine begerenzte Lagerfähigkeit aufweisen und zudem, wenn sie Casein enthalten,
konserviert werden müssen.
Der Erfindung liegt die Aufgabe zugrunde, einen Masse- und Oberflächenleim für den
pH-Bereich 4.5 - 8.5 zur Verfügung zu stellen, der nach einem einfachen Verfahren
herstellbar ist und nicht die Nachteile der herkömmlichen Invertleime besitzt.All sizing agents that contain a protective colloid are metastable preparations that only have a limited shelf life and, if they contain casein, must be preserved.
The invention has for its object to provide a mass and surface glue for the pH range 4.5 - 8.5, which can be produced by a simple process and does not have the disadvantages of conventional invert glue.
