Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur kontinuierlichen Beschichtung von Kunststoff-Bodenbelägen mit strukturierter Oberfläche, insbesondere von strukturierten PVC-Bodenbelägen, mit einer Oberflächenausrüstung.The invention relates to a method and a device for the continuous coating of plastic floor coverings with a structured surface, in particular of structured PVC floor coverings, with a surface finish.

Kunststoff-Bodenbeläge mit strukturierter Oberfläche, insbesondere sogenannte chemisch geprägte PVC-Bodenbeläge, finden heute in großem Umfang Verwendung als Fußbodenoberflächen, vor allem wegen ihrer verschiedenartigen dekorativen Oberflächengestaltung und ihrer weitgehenden Beständigkeit gegen Abnützung. Um ein gepflegtes Aussehen nach der Verlegung für einen längeren Zeitraum zu erhalten, ist aber eine Pflege der Oberfläche dieser Bodenbeläge notwendig. Eine solche wirksame Erstpflege des verlegten Bodenbelages wird jedoch bei der Verlegung durch den Lieferanten an Ort und Stelle nur sehr selten vorgenommen. Auch die Fälle, in denen der Käufer im « Do it your self »-Verfahren nach erfolgter Verlegung des Bodenbelages eine solche Erstpflege vornimmt, sind die Ausnahme. Wenn eine solche Erstpflege überhaupt durchgeführt wird, ist diese sehr häufig unzureichend, fehlerhaft oder wird zu spät vorgenommen, und sie wird vor allen Dingen auch ohne eine haftverbessernde Wärmeeinwirkung vorgenommen. Dadurch kommt es bei solchen strukturierten Bodenbelägen, insbesondere wenn diese eine helle Farbstellung aufweisen, zur irreversiblen, vorzeitigen Anschmutzungen. Es entstehen Gehzonen, 'Gummiabsatzmarkierungen usw., die dann später nicht mehr zu entfernen sind. Außerdem haben chemisch geprägte PVC-Bodenbeläge die Eigenschaft, daß der stets enthaltene Weichmacher innerhalb von Tagen und wochen durch Migration einen Weichmacherfilm auf der Bodenbelagsoberfläche ausbildet, der besonders schmutzanfällig ist und zudem wie eine Trennschicht gegenüber dem später üblicherweise vom Endverbraucher aufgebrachten Pflegemittel wirkt.Plastic floor coverings with a structured surface, in particular so-called chemically embossed PVC floor coverings, are widely used as floor surfaces today, primarily because of their diverse decorative surface designs and their extensive resistance to wear and tear. In order to maintain a well-groomed appearance after laying for a longer period, it is necessary to maintain the surface of these floor coverings. Such effective initial maintenance of the installed flooring is, however, only very rarely carried out on site by the supplier. The cases in which the buyer does such initial care in the "do it your self" procedure after the floor covering has been laid are also exceptional. If such initial care is carried out at all, it is very often inadequate, faulty or is carried out too late and, above all, it is also carried out without the effect of heat, which improves adhesion. This results in irreversible, premature soiling of such structured floor coverings, especially if they have a light color. There are walking zones, rubber heel markings, etc., which cannot be removed later. In addition, chemically embossed PVC floor coverings have the property that the plasticizer that is always present forms a plasticizer film on the surface of the floor covering by migration within days and weeks, which is particularly susceptible to dirt and also acts as a separating layer from the care products that are usually later applied by the end user.

Aus der DE-B-28 40 581 ist es bekannt, einen aus thermoplastischen Kunststoffen bestehenden strukturierten Bodenbelag mit einer durchsichtigen, widerstandsfähigen und kratzfesten Trittschicht aus einem photopolymerisierbaren Kunststoff zu versehen. Der Kunststoff wird dabei vorhangartig freifließend auf ein Substrat aufgebracht, wobei unter der Beschichtungsmasse Luftblasen eingeschlossen werden.From DE-B-28 40 581 it is known to provide a structured floor covering made of thermoplastic plastics with a transparent, resistant and scratch-resistant wear layer made of a photopolymerizable plastic. The plastic is applied to a substrate in a free-flowing curtain-like manner, air bubbles being enclosed under the coating material.

Um dies zu vermeiden, müssen daher in einem vorhergehenden, technisch aufwendigen Arbeitsschritt vor dem Auftragen des Kunststoffes wenigstens die Vertiefungen des Substrates mit einer Mischung aus einem ungesättigten Acrylat benetzt werden. Eine Vergleichmäßigung des aufgetragenen Kunststoffes kann so nicht durchgeführt werden.In order to avoid this, prior to application of the plastic, at least the depressions in the substrate must be wetted with a mixture of an unsaturated acrylate in a previous, technically complex work step. The applied plastic cannot be evened out in this way.

In der WO 82/02 681 wird ein Verfahren zur Herstellung eins dekorativen Folienmaterials durch Bedrucken einer Polyvinyl-Folie mit einer Mehrzahl von pigmentierten Plastisolen beschrieben, wobei nach dem letzten Druckvorgang und vor dem Härten eine durchsichtige Kunststoffschicht auf die dekorative Musterschicht aufgerakelt wird, worauf dann das gesamte Schichtgebilde in einem Ofen getrocknet wird. Eine Vergleichmäßigung der Oberfläche des Grundmaterials ist der Literaturstelle nicht zu entnehmen.WO 82/02 681 describes a process for producing a decorative film material by printing on a polyvinyl film with a plurality of pigmented plastisols, a transparent plastic layer being knife-coated onto the decorative pattern layer after the last printing process and before curing, followed by the entire layer structure is dried in an oven. The literature reference does not show that the surface of the base material is even.

Der Erfindung liegt nun die Aufgabe zu Grunde, ein Verfahren und eine Vorrichtung der Eingangs genannten Art zu schaffen, mit denen es auf einfache und kostengünstige Weise möglich ist, einen Bodenbelag herzustellen, der bereits fachgerecht mit einer gleichmäßigen Antischmutzausrüstung an der Oberfläche versehen ist, wodurch die oben genannten Schwierigkeiten und Erscheinungen beim Endabnehmer des Bodenbelages nicht mehr auftreten können. Zusätzlich sollen durch die Beschichtung der Bodenbelagsoberfläche in einem frischen benetzungsfähigen Zustand eine besonders gute Adhäsion und eine besonders gute Dauerhaftigkeit des Schutzfilmes erzielt werden, wie sie sonst mit den herkömmlichen Methoden nicht erreicht wird.The invention is based on the object to provide a method and a device of the type mentioned, with which it is possible in a simple and inexpensive manner to produce a flooring that is already professionally provided with a uniform anti-soiling finish on the surface, whereby the above-mentioned difficulties and phenomena can no longer occur with the end customer of the floor covering. In addition, the coating of the floor covering surface in a fresh, wettable state is intended to achieve a particularly good adhesion and a particularly good durability of the protective film, which cannot otherwise be achieved with the conventional methods.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Beschichtung der Oberfläche des Bodenbelages gleich werksseitig, anschließend an die Herstellung des Bodenbelages vorgenommen wird. Dazu wird auf den Bodenbelag mittels einer Walze als wäßriges Beschichtungsmittel eine Polymerdispersion auf der Basis von Reinacrylaten in Verbindung mit entsprechenden temporär und permanent wirkenden Weichmachern oder als lösungsmittelhaltiges Beschichtungsmittel ein Organosol auf Basis von Acrylat oder Polyurethan aufgebracht.This object is achieved in that the coating of the surface of the floor covering is carried out immediately at the factory, after the production of the floor covering. For this purpose, a polymer dispersion based on pure acrylates in conjunction with corresponding temporary and permanent plasticizers or an organosol based on acrylate or polyurethane as a solvent-containing coating agent is applied to the floor covering by means of a roller as an aqueous coating agent.

Die auf den strukturierten Bodenbelag aufgebrachte Beschichtung ist dabei in ihrer Oberflächengestaltung ungleichmäßig, weshalb die aufgetragene Beschichtung zunächst durch Anblasen mittels eines Gasstromes, z. B. Luft vergleichmäßigt wird, um auf den fertigen Bodenbelag eine gleichmäßige Schichtdicke des Auftrags zu erhalten. Anschließend wird die auf dem Bodenbelag befindliche noch feuchte Beschichtung mittels einer Wärmestrahlung getrocknet, gehärtet und fixiert.The coating applied to the structured floor covering is uneven in its surface design, which is why the applied coating is firstly blown on by means of a gas stream, e.g. B. air is evened out to get a uniform layer thickness of the order on the finished flooring. Then the still moist coating on the floor covering is dried, hardened and fixed by means of thermal radiation.

Das erfindungsgemäße Verfahren ist dabei geeignet für Beschichtung von endlosen Bodenbelägen mit einer Oberflächenausrüstung mit einer Bahnbreite des Bodenbelages bis über 4 Meter. Die Durchlaufgeschwindigkeit des Bodenbelages kann dabei 1 bis 80 m/min betragen. Als besonders geeignet hat sich eine Durchlaufgeschwindigkeit von 10 bis 30 m/min herherausgestellt.The method according to the invention is suitable for coating endless floor coverings with a surface finish with a web width of the floor covering of more than 4 meters. The throughput speed of the floor covering can be 1 to 80 m / min. A throughput speed of 10 to 30 m / min has proven to be particularly suitable.

Die Schichtdicke des Auftrages auf dem strukturierten Bodenbelag ist dabei gleichmäßig und von etwa 1 bis 50 ILm einstellbar. Mit einer Schichtdicke des Auftrages von 3 bis 20 ILm wird bereits in den meisten Fällen der angestrebte Effekt voll erreicht.The layer thickness of the application on the structured flooring is even and adjustable from about 1 to 50 ILm. With a layer thickness of 3 to 20 IL m, the desired effect is already fully achieved in most cases.

Eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens ist durch die Merkmale des Anspruches 3 gekennzeichnet.A device for performing the inventions The method according to the invention is characterized by the features of claim 3.

Weitere zweckmäßige Ausbildungen der Vorrichtung enthalten die Ansprüche 4-7.Further expedient designs of the device contain claims 4-7.

Die Erfindung wird anhand einer SchemaZeichnung weiter veranschaulicht.The invention is further illustrated using a schematic drawing.

In dieser Zeichnung ist mit 1 die von dem Produktionsvorgang zulaufende strukturierte Bodenbelagsbahn bezeichnet. Eine Wanne 2 enthält das wässrige und/oder lösungsmittelhaltige Beschichtungsmittel 3, in das eine Walze 4 eintaucht und einen entsprechenden Anteil des Beschichtungsmittels mitnimmt. Das von der Walze 4 mitgenommene Beschichtungsmittel wird dann auf die Oberfläche einer im entgegengesetzten Drehsinn umlaufenden Auftragswalze 5 übertragen. Gegen diese Auftragswalze 5 wird durch eine Umlenkwalze 6 der strukturierte Bodenbelag angedrückt und dementsprechend auf die Oberfläche des Bodenbelages das Beschichtungsmittel aufgebracht. Um einen guten Auftrag des Beschichtungsmittels auf die Oberfläche des Bodenbelages zu gewährleisten, d. h. zu bewerkstelligen, daß der Beschichtungsfilm auf die gesamte Oberfläche des strukturierten Bodenbelages, insbesondere auch auf die tiefer liegenden Flächen aufgetragen wird, hat es sich dabei als vorteilhaft herausgestellt, daß die Auftragswalze 5 eine geschlossene glatte Oberfläche aus Gummi aufweist. Nach dem Auftrag des Beschichtungsmittels auf den strukturierten Bodenbelag wird der beschichtete Bodenbelag 7 über eine weitere Umlenkwalze 8 zur Vergleichmäßigung der Auftragsschicht an einer Düse 9 vorbeigeführt, mittels derer ein Gasstrom, z. B. Luft, die Oberfläche der Auftragsschicht anbläst, wodurch sich eine ebene Oberfläche der Beschichtung ausbildet.In this drawing, 1 denotes the structured floor covering web to be tapered from the production process. A trough 2 contains the aqueous and / or solvent-containing coating agent 3, into which a roller 4 is immersed and takes a corresponding proportion of the coating agent with it. The coating agent entrained by the roller 4 is then transferred to the surface of an application roller 5 rotating in the opposite direction of rotation. The structured floor covering is pressed against this application roller 5 by a deflecting roller 6 and the coating agent is accordingly applied to the surface of the floor covering. To ensure a good application of the coating agent on the surface of the floor covering, d. H. to accomplish that the coating film is applied to the entire surface of the structured floor covering, in particular also to the lower lying surfaces, it has been found to be advantageous that the application roller 5 has a closed smooth surface made of rubber. After the coating agent has been applied to the structured floor covering, the coated floor covering 7 is guided past a nozzle 9 via a further deflecting roller 8 in order to make the application layer more uniform, by means of which a gas stream, eg. B. air, the surface of the application layer blows, whereby a flat surface of the coating is formed.

Anschließend wird der beschichtete Bodenbelag mit seiner noch fließbaren Auftragsschicht an einer Heizeinrichtung 10 vorbeigeführt und die aufgetragene Schicht getrocknet, gehärtet und fixiert. Als Heizeinrichtung wird eine Wärmestrahlungsquelle, z. B. ein IR-Strahlerfeld verwendet.The coated floor covering with its still flowable application layer is then guided past a heating device 10 and the applied layer is dried, hardened and fixed. As a heating device, a heat radiation source, for. B. uses an IR radiator field.

Durch diesen Vorgang wird die als Antischmutzausrüstung auf die Oberseite des Bodenbelags aufgebrachte Beschichtung nicht nur getrocknet, sondern durch die Wärmeeinwirkung wird auch eine gute Haftung zwischen dem Bodenbelag und der Beschichtung erreicht.This process not only dries the coating applied as anti-soiling equipment to the top of the floor covering, but also ensures good adhesion between the floor covering and the coating due to the action of heat.

AusführungsbeispielEmbodiment

Eine 4,08 Meter breite Bahn eines chemisch geprägten, strukturierten CV-Bodenbelages wird einem Presseur zugeführt, mit einer Durchlaufgeschwindigkeit von 20 m/min. In einer Wanne befindet sich eine wässrige Dispersion aus Polymethylmethacrylat und Polyäthylenglykol als Weichmacher.A 4.08 meter wide web of chemically embossed, structured CV flooring is fed to an impression roller at a throughput speed of 20 m / min. An aqueous dispersion of polymethyl methacrylate and polyethylene glycol as a plasticizer is in a tub.

Diese Dispersion ist etwa 20-gewichtsprozentig an Polymethylmethacrylat und wird mit der in einem Vorratsbehälter befindlichen entsprechenden Dispersion umgepumpt.This dispersion is about 20 percent by weight of polymethyl methacrylate and is pumped around with the appropriate dispersion located in a storage container.

Mittels einer umlaufenden, in die Dispersion eintauchenden Stahlwalze wird laufend Dispersion aus der Wanne mitgenommen und auf eine Auftragswalze übertragen, die eine Gummiummantelung besitzt.By means of a revolving steel roller immersed in the dispersion, dispersion is continuously taken out of the tub and transferred to an application roller which has a rubber coating.

Bei dem Durchlauf des CV-Bodenbelages zwischen der Umlenkwalze und der Auftragswalze wird die Oberfläche des CV-Bodenbelages mit einem dünner, zusammenhängenden, endlosen, der strukturierten Oberfläche des Belages anliegenden Dispersionsfilm beschichtet. Anschließend wird der so beschichtete CV-Bodenbelag über eine Umlenkwalze an einer Luftdüse vorbeigeführt, die mit einem etwa 40 °C warmen Luftstrom den noch nassen Auftrag anbläst und den Auftrag vergleichmäßigt. Darauf wird der vergleichmäßigte Dispersionsfilm auf den CV-Bodenbelag an einem IR-Strahlerfeld vorbeigeführt, das eine Leistung von 2 x 8 000 Kcal/m2 (2 x 33 500 KJ/m2) besitzt, und dabei der Dispersionsfilm getrocknet, gehärtet und auf die Oberfläche des CV-Bodenbelages fixiert. Die Beschichtung weist nach dem letzten Vorgang eine Stärke von etwa 6 fLm auf, was einem Auftragsgewicht von ungefähr 30 g/m2 an Beschichtungsfilm entspricht.When the CV floor covering passes between the deflecting roller and the application roller, the surface of the CV floor covering is coated with a thin, coherent, endless, dispersion film which lies against the structured surface of the covering. The CV floor covering coated in this way is then passed over a deflection roller past an air nozzle which blows the still wet application with an air stream at about 40.degree. C. and smoothes the application. The uniform dispersion film is then passed onto the CV floor covering at an IR radiator field, which has an output of 2 x 8,000 Kcal / m 2 (2 x 33,500 KJ / m 2 ), and the dispersion film is dried, hardened and exposed fixed the surface of the CV flooring. After the last process, the coating has a thickness of approximately 6 f Lm, which corresponds to an application weight of approximately 30 g / m 2 of coating film.

Darauf wird der mit der Antischmutzausrüstung versehene CV-Bodenbelag auf einer Vorratswalze aufgerollt.Then the CV floor covering with the anti-soiling equipment is rolled up on a supply roller.

Die mit der Erfindung erzielten Vorteile bestehen, insbesondere darin, daß ein Bodenbelag, insbesondere ein strukturierter PVC-Bodenbefag, gleich anschließend an den Produktionsvorgang mit einer Antischmutzausrüstung versehen wird, wobei eine gute Haftung zwischen dem Bodenbelag und der Beschichtung erreicht wird. Es wird dabei eine gleichmäßige Beschichtung des Bodenbelages erzielt, wobei auch die tieferliegenden Bereiche der Strukturierung mit dem Beschichtungsmittel versehen werden. Das Dessin wird nicht beeinträchtigt und die belagsbedingten Glanz- bzw. Mattgrade der Oberfläche des Bodenbelages können, wenn erforderlich, dabei ebenfalls erhalten bleiben.The advantages achieved by the invention consist, in particular, in that a floor covering, in particular a structured PVC floor covering, is provided with anti-soiling equipment immediately after the production process, with good adhesion between the floor covering and the coating being achieved. A uniform coating of the floor covering is achieved, with the lower areas of the structuring also being provided with the coating agent. The design is not affected and the degree of gloss or matt of the surface of the floor covering due to the covering can, if necessary, also be retained.

Selbstverständlich sind die erfindungsgemäße Verfahrensweise und die erfindungsgemäße Vorrichtung auch für die Herstellung von Belägen einsetzbar, die als Endprodukt für Wandverkleidunn, sonstige Bezüge oder für die Innenverkleidung von z. B. Automobilen Verwendung finden.Of course, the procedure according to the invention and the device according to the invention can also be used for the production of coverings which are used as end products for wall cladding, other covers or for the interior cladding of e.g. B. find use of automobiles.
