Abstract

Compressed granulate contains highly pure cellulose and/or cellulose derivative that is insoluble but swells in water, finely-divided (co)polymer of (meth)acrylic acid or salt and liquid surfactant(s) that thickens or forms a gel with water. An Independent claim is also included for the production of the compressed granulate.

Description

Die Erfindung richtet sich auf ein Granulat, das besonders gut Wasser aufnimmt und im Innern weiterleitet wodurch zum Teil eine Volumenzunahme erfolgt, so daß das Granulat als Sprengmittel für gepreßte Formkörper, wie Tabletten, geeignet ist.The invention is directed to granules that are particularly good at water records and forwards inside, which in some cases increases the volume takes place, so that the granules as disintegrants for pressed moldings, such as tablets.

Sprengmittel für Tabletten oder Granulate sind Hilfsstoffe, die den Zerfall von Tabletten oder des Granulats bei Kontakt mit Flüssigkeiten, insbesondere Wasser positiv beeinflussen. Dabei soll sowohl der Zerfall von Tabletten in grobe Teile als auch nachfolgend ein Zerfall in kleinere Partikel bewirkt und beschleunigt werden.Disintegrants for tablets or granules are auxiliary substances that disintegrate tablets or granules in contact with liquids, in particular Influence water positively. The decay of Tablets in large parts and then a disintegration into smaller ones Particles are caused and accelerated.

Als Sprengmittel für Tabletten sind eine Vielzahl anorganischer und organischer Substanzen bekannt, zum Beispiel anorganische Stoffe wie Bentonite, auch Persalze, Acetate, Alkalicarbonate/Hydrogencarbonate und Zitronensäure. Zu den bekannten organischen Verbindungen gehören Stärke, modifizierte Stärke und Stärkeabbauprodukte, Cellulose, Celluloseether, wie Methylcellulose Hydroxypropyl cellulose und Carboxymethylcellulose, Proly(meth)acrylate, Polyvinylpyrrolidon und quervernetztes Polyvinylpyrrolidon, Alginate, Gelatine und Pectine.A large number of inorganic and organic disintegrants for tablets are Substances known, for example inorganic substances such as bentonites, also persalts, acetates, alkali carbonates / hydrogen carbonates and citric acid. Known organic compounds include starch, modified Starch and starch degradation products, cellulose, cellulose ethers, such as Methyl cellulose hydroxypropyl cellulose and carboxymethyl cellulose, proly (meth) acrylates, Polyvinyl pyrrolidone and cross-linked polyvinyl pyrrolidone, Alginates, gelatin and pectins.

Bei Tabletten, die aus vorgefertigten Compounds gepreßt werden, besteht die Notwendigkeit, den Zerfall in die ursprünglichen Compounds und nachfolgend auch in Einzelbestandteile zu beschleunigen.For tablets that are made from pre-made compounds the need to disintegrate into the original compounds and subsequent to accelerate even in individual components.

Bei Tabletten, die aus nicht vorgefertigten Compounds gepreßt werden, entsteht beim Verpressen häufig eine sehr hohe Dichte, die bei Kontakt mit Wasser den gewünschten Zerfall der Tablette verzögert. Dies ist häufig unerwünscht, weil sich Bestandteile dann nur mit Verzögerung lösen. For tablets that are pressed from non-prefabricated compounds, A very high density often arises when pressing, that in contact delayed the desired disintegration of the tablet with water. This is common undesirable, because components then only come off with a delay.

Aus dem Stand der Technik ist kein Sprengmittel bekannt, das sich durch eine nichtlineare Quellkinetik auszeichnet und es ist nirgends die Verwendung von Tensiden, bevorzugt gelbildende oder mit Wasser verdickende Tenside, im Sprengmittel erwähnt. Die Verlängerung der Tablettenzerfallszeit durch bestimmte Tenside wird bisher als Nachteil beschrieben.No disintegrant is known from the prior art, which is characterized by is characterized by a non-linear source kinetics and the use is nowhere of surfactants, preferably gel-forming or water-thickening Surfactants, mentioned in the disintegrant. The prolongation of the tablet disintegration time Certain surfactants have so far been described as a disadvantage.

Diese Aufgabe wird gelöst durch ein verdichtetes Granulat, enthaltend nicht wasserlösliche, in Wasser quellbare hochreine Cellulose und/oder Cellulosederivate und feinteilige Polymere oder Copolymere von (Meth)acrylsäure oder Mischungen dieser Polymeren oder Copolymeren und ein oder mehrere flüssige nichtionische und/oder anionische und/oder amphotere Tensid(e),die zur Gelbildung oder Verdickung mit Wasser neigen, wobei durch das Verdichten eine Ausrichtung der anisotropen Cellulose bzw. Cellulosederivate erzeugt wurde.This object is achieved by a compacted granulate containing not water-soluble, water-swellable high-purity cellulose and / or Cellulose derivatives and finely divided polymers or copolymers from (Meth) acrylic acid or mixtures of these polymers or copolymers and one or more liquid nonionic and / or anionic and / or amphoteric Surfactant (s) that tend to gel or thicken with water, an alignment of the anisotropic cellulose by the compression or cellulose derivatives was generated.

Die in Wasser quellbare hochreine Cellulose wird in Form mikrokristalliner Gefüge eingesetzt, wobei die übermolekularen Strukturelemente die Form von Fibrillen aufweisen, in deren Längsrichtung sich kristalline und amorphe Bereiche abwechseln können. Als besonders geeignet haben sich Fibrillen nativer Cellulose mit einer maximalen Länge von 300 µm erwiesen. Es können sowohl mikrokristalline als auch amorphe feinteilige Cellulose und Mischungen derselben verwendet werden.The water-swellable, high-purity cellulose becomes microcrystalline in form Structure used, the super-molecular structural elements Have the shape of fibrils, in the longitudinal direction of which crystalline and can alternate amorphous areas.

Most notably particle sizes from 45 μm to 90 μm are preferred.

Teilchen mit mittleren Teilchengrößen über 150 µm zeigen zwar eine gute Sprengwirkung, sind nach dem Quellen jedoch zu groß, werden beim Waschen abfiltriert und sind auf dem Textilgut nach der Wäsche visuell als Teilchen sichtbar.Particles with average particle sizes over 150 µm show a good one Explosive effects, but are too large after swelling, become when washing filtered off and are visually as particles on the textile after washing visible.

Cellulose/Cellulosederivate werden mit Polymeren/Copolymeren von (Meth)acrylsäure oder Salzen derselben im Granulat kombiniert, das Gewichtsverhältnis kann von 100:0.5 bis 100:30, vorzugsweise von 100:1 bis 100:20 betragen, ganz besonders bevorzugt ist ein Gewichtsverhältnis von 100:1 bis 100:10, am günstigsten ist ein Gewichtsverhältnis von 100:3.Cellulose / cellulose derivatives are made with polymers / copolymers from (Meth) acrylic acid or salts thereof combined in the granulate, the weight ratio can be from 100: 0.5 to 100: 30, preferably from 100: 1 to 100: 20, a weight ratio of is very particularly preferred 100: 1 to 100: 10, the most favorable is a weight ratio of 100: 3.

Als weiteren wesentlichen Bestandteil enthält das Granulat ein oder mehrere flüssige, mit Wasser gelbildende oder verdickende Tenside, ausgewählt aus der Gruppe der nichtionischen, anionischen oder amphoteren Tenside.The granulate contains one or more other essential constituents liquid, water-forming or thickening surfactants from the group of nonionic, anionic or amphoteric surfactants.

Die nichtionischen Tenside sind ausgewählt aus Alkylpolyglucosiden, Fettsäure-Alkylolamiden, Fettsäure-Polyethylenglykolestern, Fettaminoxethylaten, Fettalkoholethoxylaten mit 3-15 Mol Ethylenoxid oder Propylenoxid, Fettsäureglyceriden, Sorbitanestern, Saccharoseestern, z.B. Saccharosepalmitat, Pentaaerythrit-Partialester, die auch ethoxyliert sein können, sowie Alkylphenol-Polyethylenglykolethern und Phenolpolyethylenglykolethern (wenn diese im jeweiligen Land eingesetzt werden dürfen)The nonionic surfactants are selected from alkyl polyglucosides, fatty acid alkylolamides, Fatty acid polyethylene glycol esters, fatty amine oxethylates, Fatty alcohol ethoxylates with 3-15 mol ethylene oxide or propylene oxide, Fatty acid glycerides, sorbitan esters, sucrose esters, e.g. Sucrose palmitate, Pentaerythritol partial esters, which can also be ethoxylated, as well as alkylphenol polyethylene glycol ethers and phenol polyethylene glycol ethers (if these can be used in the respective country)

Die anionische Tenside sind ausgewählt aus Alkylsulfaten, linearen und verzweigten Alkybenzolsulfonaten, Alkylglycerolethern, Fettalkoholpolyethylenglycolethersulfaten, Paraffinsulfonaten, Alpha-Olefinsulfonaten, Sulfosuccinaten, Phosphorsäureestern und Fettalkoholethercarboxylaten.The anionic surfactants are selected from alkyl sulfates, linear and branched alkylbenzenesulfonates, alkylglycerol ethers, fatty alcohol polyethylene glycol ether sulfates, Paraffin sulfonates, alpha olefin sulfonates, Sulfosuccinates, phosphoric acid esters and fatty alcohol ether carboxylates.

Bevorzugt sind Mengenverhältnisse von 100:2 bis 100:5The quantitative ratio of cellulose / cellulose derivatives and / or polymers / copolymers of (meth) acrylic acid or salts thereof: surfactant can from 100: 1 to 10: 1. Quantities of 100: 2 are preferred up to 100: 5

Völlig überraschend wurde gefunden, daß bei Anlagerung der erfindungsgemäßen Tenside an Cellulose bzw. deren Derivaten die Quellwirkung der erfindungsgemäßen Sprengmittelgranulate deutlich verbessert wird. Dies ist besonders überraschend, da viele konzentrierte Tenside bei Kontakt mit Wasser zur Gelbildung neigen und die Benetzung und Quellung des Sprengmittelgranulates eher behindert sein sollte. Gelbildung oder verdickende Wirkungen hat man z.B. bei Fettalkoholethoxylaten, Seifen, Fettalkylethersulfaten und Fettalkylsulfaten beobachtet.Completely surprisingly, it was found that when the inventive compounds were added Surfactants on cellulose or their derivatives have the swelling effect of the invention Disintegrant granules is significantly improved. This is Particularly surprising, since many concentrated surfactants come into contact with Water tend to gel and wetting and swelling of the disintegrant granules should be rather disabled. Gelation or thickening One has effects e.g. for fatty alcohol ethoxylates, soaps, fatty alkyl ether sulfates and fatty alkyl sulfates were observed.

Die gelbildenden oder mit Wasser verdickenden Tenside können anionisch, amphoter oder nichtionisch sein, besonders bevorzugt sind nichtionische Tenside.The gel-forming or water-thickening surfactants can be anionic, be amphoteric or nonionic, particularly preferred are nonionic Surfactants.

Es hat sich deshalb als besonders vorteilhaft erwiesen, die flüssigen Tenside zunächst in direktem Kontakt mit der Cellulose / den Cellulosederivaten zu bringen und daran anzulagern und dann die feinteiligen Polymere / Copolymere von (Meth)acrylsäure oder deren Salze in die Mischung derart einzubringen, daß die Polymerteilchen an den Fibrillen der Cellulose haften.It has therefore proven to be particularly advantageous to use the liquid Surfactants initially in direct contact with the cellulose / cellulose derivatives to bring and attach to it and then the finely divided polymers / Copolymers of (meth) acrylic acid or its salts in the mixture to be introduced in such a way that the polymer particles on the fibrils of the cellulose be liable.

Die Mischung der erfindungsgemäßen Granulatbestandteile, Cellulose/Cellulosederivate und Polymere/Copolymere von (Meth)acrylsäure und nichtionische Tenside wird dann mit üblichen Verfahren granuliert. Beispielsweise können Mischer der Firmen Vomm, Lödige, Schugi, Eirich, Henschel oder Fukae eingesetzt werden.The mixture of the granulate components according to the invention, cellulose / cellulose derivatives and polymers / copolymers of (meth) acrylic acid and nonionic surfactants are then granulated using conventional methods. For example can mixers from Vomm, Lödige, Schugi, Eirich, Henschel or Fukae can be used.

Für das Quell- und Wasseraufnahmeverhalten des erfindungsgemäßen Granulats ist die abschließende Verdichtung wesentlich. Das Verdichten unter Anwendung von Druck kann auf verschiedene Weise erfolgen.For the swelling and water absorption behavior of the granules according to the invention the final compression is essential. Compacting under Pressure can be applied in various ways.

Als besonders geeignet hat sich die Verdichtung auf Walzwerken erwiesen, deren Walzen mit unterschiedlicher Umdrehungsgeschwindigkeit laufen, so daß die Druckeinwirkung auf das Granulat im Walzenspalt noch durch Friktion ergänzt wird. Dies führt zur Ausbildung von schuppenartiger Struktur und Ausrichtung der anisotropen Cellulose/Cellulosederivate im Granulat. Compaction on rolling mills has proven to be particularly suitable whose rollers run at different speeds, so that the pressure on the granules in the nip is still due to friction is added. This leads to the formation of a scale-like structure and alignment of the anisotropic cellulose / cellulose derivatives in the granulate.

Diese Ausrichtung kann eine der Ursachen für das besonders günstige quellkinetische Verhalten dieser Ausführungsform der erfindungsgemäßen Granulate sein.This orientation can be one of the reasons for the particularly cheap source kinetic behavior of this embodiment of the invention Be granules.

Die Verdichtung des Granulats soll vorzugsweise derart sein, daß das verdichtete Granulat eine Schüttdichte von 100 g/l bis 800 g/l, bevorzugt von 200 g/l bis 600 g/l, ganz besonders bevorzugt von 300 g/l bis 500 g/l aufweist.The compression of the granules should preferably be such that the compression Granules a bulk density of 100 g / l to 800 g / l, preferred from 200 g / l to 600 g / l, very particularly preferably from 300 g / l to 500 g / l having.

Die erfindungsgemäßen Sprengmittelgranulate sind in den Formkörpern in Mengen von 0.5 Gew.% bis 10 Gew.% enthalten, vorzugsweise 2 Gew.% bis 7 Gew.% und besonders bevorzugt 3 Gew.% bis 6 Gew.%.The disintegrant granules according to the invention are in the moldings in Contain amounts of 0.5 wt.% To 10 wt.%, Preferably 2 wt.% To 7 % By weight and particularly preferably 3% by weight to 6% by weight.

Das spezifische Wasseraufnahmevermögen des erfindungsgemäßen Granulats kann gravimetrisch wie folgend bestimmt werden:
Eine definierte Granulatmenge (z.B. 2.00 g) wird in einen dünnen Papierbeutel, wie einem Teebeutel eingeschweißt und in ein Gefäß mit einem Überschuß an Wasser getaucht. Nach 3 Minuten Eintauchzeit wird der Beutel aus dem Wasser herausgenommen und 10 Minuten zum Abtropfen aufgehängt. Der Beutel wird gewogen und aus der Gewichtsdifferenz eines nassen Beutels mit und ohne Granulat die Wasseraufnahme bestimmt. Für die Bestimmung kann destilliertes Wasser oder Wasser mit definierter Härte verwendet werden.The specific water absorption capacity of the granules according to the invention can be determined gravimetrically as follows:
A defined amount of granules (eg 2.00 g) is sealed in a thin paper bag, such as a tea bag, and immersed in a vessel with an excess of water. After 3 minutes of immersion, the bag is removed from the water and hung for 10 minutes to drain. The bag is weighed and the water absorption is determined from the weight difference of a wet bag with and without granules. Distilled water or water with a defined hardness can be used for the determination.

Die auf diese Weise bestimmbare Wasseraufnahme beträgt vorzugsweise 500 bis 2000 %The water absorption which can be determined in this way is preferably 500 until 2000 %

Das erfindungsgemäße verdichtete Granulat zeichnet sich durch eine besondere Quellkinetik aus, die Ausdehnung ändert sich in Abhängigkeit von der Zeit nicht linear und soll nach möglichst kurzer Zeit ein bestimmtes Niveau erreichen. Besonders von Interesse ist das Quellverhalten in den ersten 10 Sekunden nach Berührung mit Wasser, wenn das Granulat als Sprengmittel für Formkörper verwendet werden soll.The compacted granulate according to the invention is distinguished by a special one Swelling kinetics, the expansion changes depending on the Time is not linear and should reach a certain level after the shortest possible time to reach. The swelling behavior in the first 10 seconds after contact with water when the granules as Explosives should be used for moldings.

Vorzugsweise beträgt die Volumenzunahme nach 5 Sekunden 55 Vol.% bis 225 Vol.%, wobei bei höherer Verdichtung, d.h. höherem Schüttgewicht, die Volumenzunahme größer ausfällt.
Nach 10 Sekunden beträgt die Volumenzunahme vorzugsweise 75 Vol.% bis 270 Vol.%, wobei ebenfalls die Volumenzunahme mit steigendem Schüttgewicht zunimmt.The increase in volume after 5 seconds is preferably 55% by volume to 225% by volume, the increase in volume being greater with higher compaction, ie higher bulk density.

Der erste Schritt des Verfahrens beinhaltet einen Misch- und Granulierungsvorgang, bei dem Vorcompounds durch Agglomerationsverfahren hergestellt werden. Diese Vorcompounds bilden eine rieselfähige und grobkörnige Ware, die einen bestimmten Feuchtegrad hat. Im nächsten Schritt werden diese Vorcompounds mechanisch verdichtet. Die Produkte können zwischen zwei Druckflächen in Walzenverdichtern, z. B. glatt oder profiliert, verdichtet werden. Sind bestimmte Gleiteigenschaften vorhanden, so kann die Verdichtung in Extrudern oder Flachmatrizenpressen zu Matrizen erfolgen. Der Ausstoß des Kompaktates erfolgt als Strang.
