Abstract

A glue contains enzymatically disaggregated starch as the largest part by weight of the solid matter fraction of the glue. The starch is preferably disaggregated at the α-1,4-bond. The glue is particularly useful in the tobacco industry for gluing the longitudinal seam and the filter rod. It is characterised by a uniform width of the seam, by few deposits on the dispensing nozzles, by no ropiness and by a high strength.

Description

"Klebstoff mit enzvmatisch abgebauter Stärke" "Adhesive with degraded starch"
Die Erfindung betrifft einen wäßrigen Klebstoff mit enzymatisch abgebauter Stärke sowie dessen Herstellung und Verwendung in der Zigarettenindustrie.The invention relates to an aqueous adhesive with enzymatically degraded starch and its production and use in the cigarette industry.
Zum Verkleben von Zigaretten werden zunehmend natürliche Rohstoffe eingesetzt. So werden zum Beispiel für die maschinelle Längsnahtverleimung von Zigarettenhüllen anstelle der bislang ein¬ gesetzten Dispersionsleime nach der DE 2619708 Klebstoffgemische auf Gelatine-Basis beschrieben. Derartige Klebstoffe erfüllen je¬ doch nicht alle Anforderungen, die an einen Klebstoff zur maschi¬ nellen Längsnahtverleimung unter Verwendung von in der Zigaretten¬ industrie üblichen Leimscheiben- und DüsenauftragsSystemen zu stellen sind. Sie liegen hinsichtlich ihrer Struktur zwischen wä߬ rigen Systemen und Schmelzklebstoffen und müssen aus beheizten Ap¬ paraturen auf die zu verklebenden Papierbereiche aufgetragen wer¬ den. Wie bei allen Klebstoffen auf Basis tierischer Proteine be¬ steht beim Erhitzen die Gefahr der Zersetzung und der Entwicklung unangenehmer Gerüche.Natural raw materials are increasingly being used to glue cigarettes. For example, for machine longitudinal seam gluing of cigarette tubes instead of the previously used dispersion glues according to DE 2619708, adhesive mixtures based on gelatin are described. However, such adhesives do not meet all the requirements which are to be placed on an adhesive for mechanical longitudinal seam gluing using glue disc and nozzle application systems customary in the cigarette industry. In terms of their structure, they lie between aqueous systems and hotmelt adhesives and must be applied to the paper areas to be bonded from heated apparatuses. As with all adhesives based on animal proteins, there is a risk of decomposition and the development of unpleasant odors when heated.
Es sind auch gut fließende Klebstoffe auf Naturprodukt-Basis be¬ kannt. So beschreibt die EP 0368136 Bl die Verwendung von Gummiarabicum enthaltenden Klebstoffgemischen zur Längsnahtverleimung von Zigarettenhüllen. Diese Klebstoffgemische enthalten auf 100 Gew.-Teile Wasser 40 bis 120 Gew.-Teile Gummiarabicum, 3 bis 80 Gew.-Teile wasserlösliche Stärkeabbaupro¬ dukte und/oder Carboxymethylstärke und/oder verkleisterte Stärke sowie gegebenenfalls übliche Konservierungsmittel in wäßriger Lö¬ sung mit einer Viskosität von 1000 bis 15000 mPas nach Brookfield bei 20 °C. Zu den erfindungsgemäß einzusetzenden wasserlöslichen Stärkeabbauprodukten gehören oxydativ oder hydrolytisch z.B. enzy¬ matisch abgebaute Stärken und Dextrine. Nachteilig bei diesen Klebstoffen sind die ungleichmäßige Nahtbreite, Ablagerungen an der Düse sowie Fadenziehen des Klebstoffes an der Düse.Well flowing adhesives based on natural products are also known. For example, EP 0368136 B1 describes the use of adhesive mixtures containing gum arabic for the longitudinal seam gluing of cigarette tubes. These adhesive mixtures contain 40 to 120 parts by weight of gum arabic, 3 to 80 parts by weight of water-soluble starch degradation products and / or carboxymethyl starch and / or gelatinized starch and, if appropriate, conventional preservatives in aqueous solution with a viscosity of per 100 parts by weight of water Brookfield 1000 to 15000 mPas at 20 ° C. The water-soluble starch degradation products to be used according to the invention include oxidatively or hydrolytically, for example, enzymatically degraded starches and dextrins. Disadvantages of these adhesives are the uneven seam width, deposits on the nozzle and threading of the adhesive on the nozzle.
Ausgehend von diesem Stand der Technik besteht die erfindungsgemäße Aufgabe darin, eine sichere und dauerhafte Verleimung von Längs¬ nähten von Zigarettenhüllen mit den in der Zigarettenindustrie üb¬ lichen Maschinen zu gewährleisten, insbesondere unter Berücksich¬ tigung der dort erforderlichen hohen Produktionsgeschwindigkeiten von 10000 Zigaretten pro Minute unter Verwendung von Düsenauf¬ tragssystemen für die Längsnahtverklebung und unter Verwendung von Walzenauftragssystemen für die Filteranklebung. Dabei sollen die oben angeführten Nachteile vermieden werden.Starting from this prior art, the object of the invention is to ensure a safe and permanent gluing of longitudinal seams of cigarette tubes with the machines customary in the cigarette industry, in particular taking into account the high production speeds of 10,000 cigarettes per minute required there using nozzle application systems for longitudinal seam bonding and using roller application systems for filter bonding. The disadvantages mentioned above should be avoided.
Die Erfindung ist den Patentansprüchen zu entnehmen. Sie besteht im wesentlichen in einem wäßrigen Klebstoff mit enzymatisch abgebauter Stärke, wobei kein anderer Stoff einen gewichtsmäßig größeren An¬ teil am Feststoffgehalt hat. Vorzugsweise ist der Anteil der enzy¬ matisch abgebauten Stärke am größten. Der Feststoffgehalt wird ge¬ mäß DIN 53189 bestimmt (Trocknung bei 105 °C bis zur Gewichtskon¬ stanz).The invention can be found in the claims. It essentially consists of an aqueous adhesive with enzymatically degraded starch, with no other substance having a larger proportion by weight of the solids content. The proportion of the enzymatically degraded starch is preferably greatest. The solids content is determined in accordance with DIN 53189 (drying at 105 ° C. to constant weight).
Neben der enzymatisch abgebauten Stärke können noch weitere Binde¬ mittel anwesend sein, z.B. native Stärke, substituierte Stärke und Cellulosederivate. Mischungen von enzymatisch abgebauter Stärke mit nicht abgebauter Stärke erlauben höhere Maschinengeschwindigkeiten bei sehr guten Klebeergebnissen. Das Mischungsverhältnis von abgebauter zu nicht abgebauter Stärke sollte zweckmäßiger 1 : ≤ 1 betragen, vorzugs¬ weise 1 : 0,5 bis 0,1. Mischungen außerhalb dieses Bereiches sind möglich, jedoch mit Nachteilen in mindestens einer Hinsicht ver¬ bunden.In addition to the enzymatically degraded starch, other binders may also be present, for example native starch, substituted starch and cellulose derivatives. Mixtures of enzymatically degraded starch with undegraded starch allow higher machine speeds with very good adhesive results. The mixing ratio of degraded to undegraded starch should advantageously be 1: 1 1, preferably 1: 0.5 to 0.1. Mixtures outside this range are possible, but they have disadvantages in at least one respect.
Außerdem kann der Klebstoff noch Additive zur Erzielung bestimmter Eigenschaften enthalten, insbesondere Konservierungsmittel. Als Konservierungsmittel eignen sich die in der Klebstoff- und Ta¬ bakindustrie üblichen Mittel gemäß der deutschen Tabakverordnung, insbesondere Kaliumsorbat und/oder p-Hydroxybenzoesäureester.The adhesive may also contain additives to achieve certain properties, in particular preservatives. Suitable preservatives are the agents customary in the adhesive and tobacco industry according to the German tobacco regulation, in particular potassium sorbate and / or p-hydroxybenzoic acid ester.
In dem Feststoffgehalt hat die enzymatisch abgebaute Stärke den größten Anteil, insbesondere liegt ihr Anteil über 50 Gew.-%, be¬ zogen auf die Bindekomponente. Vorzugsweise wird sie als alleiniges Bindemittel verwendet.In the solids content, the enzymatically degraded starch has the largest share, in particular its share is above 50% by weight, based on the binding component. It is preferably used as the sole binder.
In dem erfindungsgemäßen Klebstoff kommen auf 100 Gew.-Teile Wasser bis zu 100 Gew.-Teile an Bindemittel, vorzugsweise 5 bis 80 Gew.-Teile.In the adhesive according to the invention there are up to 100 parts by weight of binder, preferably 5 to 80 parts by weight, per 100 parts by weight of water.
Der enzymatische Abbau von Stärke ist bekannt. Für die Erfindung besonders geeignet sind Stärkeabbauprodukte, bei denen überwiegend die -l,4-Bindung gespalten wurde und weniger die -l,6-Bindung oder die α-l,3-Bindung. Insbesondere sollte die Stärke mit der α-l,4-D-Glucan-glucohydrolase abgebaut worden sein, vorzugsweise mit einer α-Atπylase und zwar einer Fungal-oc-Amylase.The enzymatic breakdown of starch is known. Starch degradation products are particularly suitable for the invention, in which predominantly the -1,4 bond has been split and less the -1,6 bond or the α-1,3 bond. In particular, the starch should have been broken down with the α-1,4-glucan-glucohydrolase, preferably with an α-Atπylase, namely a fungal-oc-amylase.
Ausgangsprodukte für die abgebauten Stärkeprodukte sind vorzugs¬ weise chemisch nicht modifizierte Lebensmittelstärken wie z.B. Wachsmais-, Kartoffel-, Tapioka- und Weizenstärke. Es können aber auch chemisch modifizierte Stärken eingesetzt werden, wenn sie nur aus einer Komponente bestehen, z.B. acetyliertes Distärkeadipat oder N-Oktenylsuccinat.Starting products for the degraded starch products are preferably chemically unmodified food starches such as Waxy corn, potato, tapioca and wheat starch. However, chemically modified starches can also be used if they consist of only one component, for example acetylated distarch adipate or N-octenyl succinate.
Davon ausgehend wird der enzymatische Abbau ganz allgemein unter folgenden Bedingungen durchgeführt:Based on this, the enzymatic degradation is generally carried out under the following conditions:
Die Reaktionstemperatur beträgt 30 bis 60 °C, insbesondere 45 bis 55 °C.The reaction temperature is 30 to 60 ° C, especially 45 to 55 ° C.
Der pH-Wert beträgt 4 bis 8, insbesondere 5 bis 7. Das Enzym wird hinzugefügt in einer Menge von 1 bis 300 ppm, insbesondere 10 bis 30 ppm, bezogen auf die abzubauende Stärke. Das Stärkeausgangsprodukt wird eingesetzt in einer Menge von 10 bis 70, insbesondere von 25 bis 40 Gew.-%, bezogen auf das wäßrige System.The pH is 4 to 8, in particular 5 to 7. The enzyme is added in an amount of 1 to 300 ppm, in particular 10 to 30 ppm, based on the starch to be broken down. The starch starting product is used in an amount of 10 to 70, in particular 25 to 40,% by weight, based on the aqueous system.
Der enzymatische Abbau wird fortgeführt, bis zur Erreichung der Viskosität von 1000 bis 20000 mPa-s, insbesondere bis 2000 bis 6000 mPa*s nach Brookfield.The enzymatic degradation is continued until the viscosity of 1000 to 20,000 mPa-s, in particular up to 2,000 to 6,000 mPa * s according to Brookfield.
Der enzymatische Abbau dauert im allgemeinen 5 Min. bis 24 Std., insbesondere 10 bis 60 Minuten.The enzymatic breakdown generally takes 5 minutes to 24 hours, in particular 10 to 60 minutes.
Zur Beendigung des enzymatisehen Abbaues wird das Enzym ther¬ misch denaturiert. Das erhaltene Reaktionsgemisch wird nun zu dem erfinduπgsge äßen Klebstoff konfektioniert, indem gegebenenfalls eine weitere Binde¬ mittel-Komponente hinzugefügt wird, soweit das nicht schon vor der Reaktion geschah. Außerdem werden nun die Additive hinzugefügt, insbesondere das Konservierungsmittel.To end the enzymatic degradation, the enzyme is thermally denatured. The reaction mixture obtained is now made up into the adhesive according to the invention, in which case a further binder component is added, if this has not already been done before the reaction. In addition, the additives are now added, especially the preservative.
Die Viskosität des erfindungsgemäßen Klebstoffes wird der Auf¬ tragsart sowie der dabei verwendeten Maschinen angepaßt. Für die Hochleistungsmaschinen in der Zigarettenindustrie sollte die Vis¬ kosität im Bereich von 1000 bis 20000, insbesondere 2000 bis 6000 Pas liegen, gemessen nach Brookfield bei 23 °C (RVT) (ISO 2555).The viscosity of the adhesive according to the invention is adapted to the type of application and the machines used. For the high-performance machines in the cigarette industry, the viscosity should be in the range from 1000 to 20,000, in particular 2,000 to 6000 Pas are measured according to Brookfield at 23 ° C (RVT) (ISO 2555).
Die erfindungsgemäßen Klebstoffe sind vielseitig zu verwenden, insbesondere um Papier miteinander zu verkleben. Vor allem eignen sie sich jedoch bei der Zigarettenherstellung, insbesondere zur Verklebung der Längsnaht und der Filteran lebung. Von besonderer Bedeutung ist, daß die erfindungsgemäßen Klebstoffe dabei auf üb¬ lichen Maschinen der Zigarettenindustrie verwendet werden können. So werden die erfindungsgemäßen Klebstoffgemische in üblichen Zi¬ garettenfertigungsmaschinen über Düsen auf die zu verleimenden Längsnahtbereiche der Zigarettenhüllen aufgetragen und ergeben eine wirksame Verleimung. Der Auftrag der Klebstoffgemische erfolgt üb¬ licherweise bei Umgebungstemperatur. Bei höher viskosen Klebstoffgem sehen kann jedoch eine geringfügige Erwärmung notwen¬ dig sein. In den meisten Fällen reicht es jedoch aus, wenn nur die Auftragsdüsen beheizt werden. Ebenso ist die Verwendung des erfindungsgemäßen Klebstoffes auf den Walzenauftragssystemen für die Filteranklebung möglich. Von besonderer Bedeutung ist, daß da¬ bei Geschwindigkeiten bis zu 10000 Zigaretten pro Minute bei einbahniger Fahrweise ermöglicht werden.The adhesives according to the invention can be used in a variety of ways, in particular to bond paper to one another. Above all, however, they are suitable for the manufacture of cigarettes, especially for gluing the longitudinal seam and filtering life. It is of particular importance that the adhesives according to the invention can be used on conventional machines in the cigarette industry. Thus, the adhesive mixtures according to the invention are applied in conventional cigarette manufacturing machines via nozzles to the longitudinal seam regions of the cigarette cases to be glued and result in effective gluing. The adhesive mixtures are usually applied at ambient temperature. In the case of highly viscous adhesives, however, slight heating may be necessary. In most cases, however, it is sufficient if only the application nozzles are heated. It is also possible to use the adhesive according to the invention on the roller application systems for filter adhesion. It is particularly important that speeds of up to 10,000 cigarettes per minute are made possible with a single-lane driving style.
Gegenüber den in der EP 368136 beschriebenen Klebstoffen haben die erfindungsgemäßen Klebstoffe folgende Vorte le: gleichmäßigere Nahtbreite, geringere Ablagerungen an der Düse, kein Fadenziehen und höhere Festigkeit. Die Erfindung wird nun anhand eines Beispieles im einzelnen be¬ schrieben:Compared to the adhesives described in EP 368136, the adhesives according to the invention have the following advantages: more uniform seam width, less deposits on the nozzle, no stringing and higher strength. The invention will now be described in detail using an example:

Zu 60 Gewichtsteilen Wasser wurden 40 Gewichtsteile einer mo¬ difizierten Stärke (acetyliertes Distärkeadipat) bei 20 °C portionsweise unter Rühren zugesetzt. Sobald die Stärke voll¬ ständig gelöst war, wurde der pH-Wert geprüft (pH 5,6) und der gesamte Ansatz auf 50 °C erwärmt. Nun wurden 0,0025 Gew.-% (25 ppm) - bezogen auf die Stärke - einer Fungal-α-Amylase hinzu¬ gefügt und für 20 Min. bei 50 °C weitergerührt. Schließlich wurde 30 Min. lang auf 100 °C erhitzt und dann unter 60 °C ab¬ gekühlt.40 parts by weight of a modified starch (acetylated distarch adipate) were added to 60 parts by weight of water at 20.degree. C. while stirring. As soon as the starch was completely dissolved, the pH was checked (pH 5.6) and the entire batch was heated to 50 ° C. Now 0.0025% by weight (25 ppm) - based on the starch - of a fungal α-amylase was added and stirring was continued at 50 ° C. for 20 minutes. Finally, the mixture was heated to 100 ° C. for 30 minutes and then cooled below 60 ° C.
B) Konfektionierung und Charakterisierung des Klebstoffes.B) Packaging and characterization of the adhesive.
Zu der gemäß Punkt A) abgebauten Stärke wurden 0,2 Gew.-% - bezogen auf die Stärke-Trockensubstanz - eines Konservie¬ rungsmittels gegeben, welches aus einem Gemisch aus Ethyl- und Propyl-p-Hydroxybenzoesäureester bestand. Zum Schluß wurde die Viskosität auf 3000 bis 3500 mPa-s nach Brookfield (ISO 2555, 23 °C, RVT) eingestellt.To the starch degraded according to point A), 0.2% by weight, based on the starch dry substance, of a preservative which consisted of a mixture of ethyl and propyl p-hydroxybenzoic acid esters was added. Finally, the viscosity was adjusted to 3000 to 3500 mPa-s according to Brookfield (ISO 2555, 23 ° C, RVT).

Die vorstehend genannten Klebstoffgemisehe wurden in einer handelsüblichen Zigarettenmaschine der Fa. Hauni getestet. Die Verleimungsdüsen waren übliche Düsen mit beheizbarem Kopf. Die Verklebung wurde unter folgenden Bedingungen durchgeführt: Maschine Protos 90 S, Düse 1,6 mm mit Pumpe, Heizung ca. 300 bis 320 °C, Zigarettenmarke R6 (100 mm), Geschwindigkeit 6000 Zigaretten pro Min. Dabei traten keine Probleme auf, insbesondere traten innerhalb der Versuchsdauer von 30 Min. keine Ablagerungen an der Düse auf. Weiterhin waren keine Verschmutzungen in der Formatkammer zu be¬ merken. Es ergab sich eine ausgezeichnete Klebefestigkeit der Längsnähte. Die Nahtbreite war gleichmäßig, wie die Anfärbung mit einer Jodlösung zeigte. Beim gewaltsamen Trennen der Nähte zeigte sich eine Verfilzung der Klebebereiche, was eine Festigkeit nahe am Materialbruch anzeigt. The adhesive mixtures mentioned above were tested in a commercially available cigarette machine from Hauni. The gluing nozzles were conventional nozzles with a heated head. The bonding was carried out under the following conditions: Protos 90 S machine, 1.6 mm nozzle with pump, heating approx. 300 to 320 ° C., cigarette brand R6 (100 mm), speed 6000 cigarettes per minute. There were no problems, in particular occurred within no deposits on the nozzle during the test period of 30 min. Furthermore, no contamination was noted in the format chamber. The longitudinal seams had excellent adhesive strength. The seam width was uniform, as shown by the staining with an iodine solution. When the seams were forcibly separated, the adhesive areas became matted, indicating strength close to the material breakage.
