Abstract

The multilayer paper has a base layer of unbleached fibres or fibres from used paper materials. The covering layer is a white or coloured coating instead of a white fibre layer. Also claimed is a production process where the fibre layer is produced without an additional bleached cellulose covering layer, to be passed to an application station for coating.

Description

Die Erfindung betrifft ein mehrschichtiges Papier sowie ein Verfahren und eine Vorrichtung zur Herstellung dieses mehrschichtigen Papiers gemäß dem Oberbegriff des ersten Anspruches sowie des Anspruches 4 und 9.The invention relates to a multilayer paper and to a method and a device for the production of this multi-layer paper according to the preamble of the first Claim and claims 4 and 9.

Bei der Herstellung von Papieren mit spezifischen Anwendungsprofilen, insbesondere Verpackungspapiere wird derzeit unter anderem versucht Papiere herzustellen, die in ihrer Z-Achse (senkrecht zur Oberfläche stehende Achse) bezüglich ihrer Faser- und Feststoffkonzentration eine starke Abhängigkeit von der Tiefe besitzen. So wird einerseits versucht mit Hilfe von Mehrschichtstoffaufläufen geringwertige Materialien (Altpapierbasis) in die Mittelschicht des Papiers einzulagern und die hochwertigen beziehungsweise teuren Materialien nur auf den Außenschichten oder einer Außenschicht aufzubringen, wo sie im wesentlichen die Güte des Papiers bestimmen, um so zum Beispiel für die Bedruckbarkeit geeignet zu sein.In the manufacture of papers with specific application profiles, in particular Packaging papers are currently trying to produce papers that are used in its Z axis (axis perpendicular to the surface) with respect to its fiber and Solid concentration have a strong dependence on depth. So on the one hand tries low-quality materials with the help of multi-layer headboxes (Waste paper base) in the middle layer of the paper and the high quality respectively expensive materials only on the outer layers or an outer layer where they essentially determine the quality of the paper, and so on For example, to be suitable for printability.

Auf die EP 0 651 092 A1 wird verwiesen. In dieser Schritt wird ein Mehrschichtenstoffauflauf, beziehungsweise ein Verfahren zur Herstellung eines mehrschichtigen Papiers dargestellt, mit dem es möglich ist, die Stoffsuspension der äußeren Schichten gezielt mit den gewünschten Materialien anzureichern und damit dem gewünschten Profil der Konzentration über die Z-Achse (Smily-Profil = in der Mitte geringe und an den Rändern hohe Konzentration) möglichst nahe zu kommen um auf der Oberseite des Papiers eine möglichst weiße und gut bedruckbare Oberfläche zu erhalten.Reference is made to EP 0 651 092 A1. In this step, a multilayer headbox, or a method for producing a multilayer Paper presented with which it is possible to suspend the material of the outer layers targeted enrichment with the desired materials and thus the desired Profile of the concentration across the Z axis (Smily profile = low in the middle and on the edges of high concentration) to get as close as possible to get on the top to get the surface of the paper as white as possible and easily printable.

Ein anderes Verfahren benutzt mehrere Stoffaufläufe (Sekundärstoffaufläufe) mit denen hintereinander einzelne Papierlagen mit unterschiedlichen Eigenschaften auf ein oder mehrere Langsiebe aufgetragen werden und so ein mehrlagiges Papier entsteht, das auf mindestens einer Seite aus einer hochwertigen, meistens gebleichten bedruckbaren Zellstofflage besteht (

Figure 00010001
z.B. White Top Liner"). Another process uses several headboxes (secondary headboxes) with which individual layers of paper with different properties are applied in succession to one or more Fourdrinier sieves, creating a multi-layer paper that consists of a high-quality, mostly bleached, printable cellulose layer on at least one side (
Figure 00010001
e.g. White Top Liner ").

Allen oben genannten Verfahren haftet das Problem an, daß bei der Schichten- bzw. Lagenbildung sehr viel Entwässerungsenergie notwendig ist und andererseits der maschinelle Aufwand zur Herstellung erheblich ist.All of the above-mentioned processes have the problem that the layer or Layer formation requires a great deal of drainage energy and, on the other hand, mechanical Manufacturing effort is significant.

Vor allem aber gehen alle oben genannten Verfahren davon aus, als Rohstoff teuren gebleichten Zellstoff oder deinkten Faserstoff zu verwenden.Above all, however, all of the above methods assume that they are expensive as a raw material to use bleached pulp or deinked pulp.

Ein weiteres Problem besteht darin, daß derzeit viele Papiermaschinen in Betrieb sind, die bezüglich ihrer Qualität des hergestellten Papiers den heutigen Anforderungen nicht mehr genügen.Another problem is that many paper machines are currently in operation, the current requirements with regard to the quality of the paper produced no longer suffice.

Aufgabe der Erfindung ist es, ein neues einfacher und billiger herzustellendes Produkt (Papier) zu schaffen, welches hinsichtlich seiner Bedruckbarkeit eine bessere Oberfläche bietet.The object of the invention is to produce a new product which is simpler and cheaper To create (paper) which has a better surface in terms of its printability offers.

Eine zweite Aufgabe der Erfindung ist es ein Verfahren und eine Vorrichtung zu entwickeln, mit denen eine Reduktion der Entwässerungsenergie möglich ist und nur einen geringen maschinellen Aufwand erfordert.A second object of the invention is to develop a method and a device with which a reduction of the drainage energy is possible and only one requires little mechanical effort.

Die Aufgabe der Erfindung wird durch die kennzeichnenden Merkmale der Ansprüche 1 (Papier), 4 (Verfahren) und 9 (Vorrichtung) gelöst.The object of the invention is achieved by the characterizing features of claims 1 (Paper), 4 (method) and 9 (device) solved.

Erfindungsgemäß wird ein solches Papier vorgeschlagen, das als Topschicht (Deckschicht) keine aus teuren Rohstoffen bestehende Papierlage, sondern einen Deckstrich enthält.According to the invention, such a paper is proposed as a top layer (Top layer) not a paper layer consisting of expensive raw materials, but one Contains dash.

Die Erfinder haben erkannt, daß mit der erfindungsgemäßen Lösung bestehende Papierherstellungsmaschinen für einlagige Papiere auf einfache Weise auf ein zweilagiges Produkt (einlagige Papierlage und Deckstrich) umrüstbar sind und in überraschender Weise die obengenannten gewünschten Eigenschaften erreicht werden. The inventors have recognized that existing paper manufacturing machines with the solution according to the invention for single-ply papers in a simple way on a two-ply Product (single-ply paper and top coat) are convertible and surprising Way the above desired properties can be achieved.

Erfindungsgemäß wird ein Verfahren zur Herstellung eines Papiers oder Kartons mit mindestens einer nicht Papierfasern enthaltenen, insbesondere weißen Deckschicht vorgeschlagen, wobei eine Faserstofflage mit einem Stoffauflauf und einem anschließenden Former oder Langsieb erzeugt wird. Die Faserstofflage wird mit mindestens einer Pressenpartie und einer anschließenden Trockenpartie getrocknet. Dabei kann die Naß- und/oder die Trockenpartie mit einer Leim- oder Filmpresse oder einem anderen Coater ausgerüstet sein. Mindestens ein Strich wird mit Hilfe eines Coaters oder einer Filmpresse aufgetragen, der dem Papier die Oberschicht (Topschicht) mit den besonderen Eigenschaften, wie zum Beispiel der guten Bedruckbarkeit oder einem besonderen Aussehen z.B. marmoriert (mottled), verleiht.According to the invention, a method for producing a paper or cardboard is used at least one, in particular white top layer, not containing paper fibers proposed, a fiber layer with a headbox and a subsequent Shaper or Fourdrinier wire is produced. The fiber layer is at least a press section and then a drying section. It can the wet and / or the dryer section with a glue or film press or another Be equipped. At least one stroke is made with the help of a coater or applied to a film press, which gives the paper the top layer (top layer) with the special properties, such as good printability or a special one Appearance e.g. marbled (mottled), gives.

Das Verfahren kann ein on-line- oder ein off-line-Verfahren sein.The process can be an on-line or an off-line process.

In eine bestehende Papiermaschine zur Herstellung von Papier- oder Kartonbahnen kann ohne Änderung des Maschinenkonzeptes, also der bestehenden Papiermaschine, zwischen Naßpartie und Wickelmaschine wenigstens eine Streichvorrichtung eingebaut werden, um die laufende Papier- oder Kartonbahn mit dem Deckstrich anstelle der bisherigen teureren weißen" - Faserstoffschicht (Papierlage) zu versehen.In an existing paper machine for the production of paper or cardboard webs, at least one coating device can be installed between the wet end and the winding machine without changing the machine concept, i.e. the existing paper machine, in order to replace the running paper or cardboard web with the top coat instead of the previous, more expensive one white "- fiber layer (paper layer).

Wie oben schon erwähnt, kann der Deckstrich als Einfach- oder Mehrfachstrich mit oder ohne Zwischentrocknung aufgebracht werden.As mentioned above, the top coat can be used as a single or multiple stroke or applied without intermediate drying.

Als vorteilhaftes Gesamt-Strichgewicht hat sich dabei 1 bis 25 g/m2 herausgestellt.1 to 25 g / m2 has been found to be an advantageous overall coat weight.

Die, erfindungsgemäß keine teuren gebleichten Rohstoffe enthaltende Faserstofflage läßt sich bestens mit dem Deckstrich abdecken. Der Deckstrich (Einfach- oder Mehrfachstrich) kann zum einen nur aus Farbe bestehen, wobei die Farbe wiederum aus Additiven, Pigmenten und Binder besteht, die in Flüssigkeit (vorzugsweise Wasser) suspendiert sind.
Zum anderen kann der Deckstrich zusätzlich zur Farbe noch Faserstoffanteile enthalten. The fibrous layer, which according to the invention contains no expensive bleached raw materials, can best be covered with the top coat. On the one hand, the top coat (single or multiple coat) can consist only of color, the color in turn consisting of additives, pigments and binders which are suspended in liquid (preferably water).
On the other hand, the top coat can also contain fiber in addition to the color.

Falls gewünscht, können die Eigenschaften (Feststoffgehalt, Auftragsmenge, Zusammensetzung, Viskosität, Pigmentgröße etc.) des Deckstriches entsprechend dem gewählten Auftragswerk so eingestellt werden, daß beispielsweise ein homogener oder marmorierter Eindruck entsteht. Dieses Aussehen kann selbstverständlich auch mit einem Rakelelement als Auftragsorgan, welches eine besondere definierte Oberfläche aufweist, erzeugt werden.If desired, the properties (solids content, application quantity, composition, Viscosity, pigment size etc.) of the top coat according to the chosen one Commissioned work can be set so that, for example, a homogeneous or marbled impression. This look can of course also with a doctor element as an application element, which has a special defined surface has to be generated.

Das mit dem Deckstrich versehene Papier kann anschließend noch in an sich bekannter Weise geglättet werden in Glätteinrichtungen mit hartem Nip; mit hartem heißen Nip; Soft-Nip; oder heißem Soft-Nip oder beliebigen Kombinationen daraus.The paper provided with the top coat can then still be known Be smoothed in smoothing devices with hard nip; with hard hot Nip; Soft nip; or hot soft nip or any combination of these.

Der optimalsten Glätteffekte werden dabei in einer Glätteinrichtung erzielt, die einen sogenannten Breit-Nip aufweist.The most optimal smoothing effects are achieved in a smoothing device that one has so-called wide nip.

Besondere Vorteile des erfindungsgemäßen Verfahrens und der Vorrichtung sind:

  • Aufgrund der nicht mehr notwendigen Entwässerung der Topschicht reduziert sich der Energiebedarf bei der Entwässerung und Trocknung.
  • Die Materialkosten sind reduziert, da das aufgetragene Streichmedium billiger als der Faserstoff ist.
  • Der maschinelle Aufwand zur Herstellung des Papiers ist geringer, da ein einfacher Stoffauflauf mit einem nachfolgenden Coater (z.B. Bladecoater, Speedcoater, Speedsizer, SDTA, Freistrahldüsenauftragswerk) für das direkte oder indirekte Streichen genügt.
  • Das hergestellte Produkt zeichnet sich durch eine höhere Lagenfestigkeit (Spaltfestigkeit) aus, da hier der bei einem Mehrlagenpapier notwendige Gautschprozeß entfällt.
  • Mit Hilfe des Streichmediums kann dem Produkt sehr einfach eine sehr gute optische Eigenschaft und Bedruckbarkeit mitgegeben werden.
  • Die optische Dichte der Deckschicht ist größer als die einer weißen Faserstofflage und kann homogener aufgetragen werden.
Particular advantages of the method and the device according to the invention are:
  • Due to the no longer necessary drainage of the top layer, the energy requirement for drainage and drying is reduced.
  • The material costs are reduced because the coating medium applied is cheaper than the fibrous material.
  • The mechanical effort for the production of the paper is less, since a simple headbox with a subsequent coater (eg blade coater, speed coater, speedsizer, SDTA, free jet nozzle applicator) is sufficient for direct or indirect coating.
  • The manufactured product is characterized by a higher layer strength (splitting strength), since the rubber process necessary for a multi-layer paper is omitted here.
  • With the help of the coating medium, the product can very easily be given a very good optical property and printability.
  • The optical density of the top layer is greater than that of a white fiber layer and can be applied more homogeneously.
