Abstract

Verfahren zur Verbesserung der Gebrauchseigenschaften von Tufted-Bodenbelägen, das darin besteht, daß man bei der Herstellung der Tufted-Bodenbeläge die für den Vorstrich und/oder die für den Zweitstrich erforderlichen Dispersionen oder Latices vor ihrer Compoundierung mit einem Fluortensid der Formel Rf-C2H4O-R vermischt, wobei Rf einen Rest C6F13, C8F17, C10F21 oder C12F25, R eine Gruppe der Formeln <IMAGE> M und M' Na, K oder NH4 und n eine Zahl von 4 bis 8 bedeuten. Das Fluortensid erhöht die Noppenfestigkeit der Polfäden und die Haftfestigkeit des Zweitrückens.Process for improving the performance properties of tufted floor coverings, which consists in preparing the tufted floor coverings with the dispersions or latices required for the primer coat and / or the second coat coat before they are compounded with a fluorosurfactant of the formula Rf-C2H4O- R mixed, where Rf is a radical C6F13, C8F17, C10F21 or C12F25, R is a group of the formulas <IMAGE> M and M 'Na, K or NH4 and n is a number from 4 to 8. The fluorosurfactant increases the pimple strength of the pile threads and the adhesive strength of the second back.

Description

Die Einbindung der Polfäden in das Grundgewebe von Tufted-bodenbelägen erfolgt durch einen sogenannten Vorstrich mit Naturlatex, Syntheselatex z.B. auf der Basis Butadien Styrol 40 : 60 oder 60 : 40, mit Kunststoffdispersionen beispielsweise auf der Basis Polyvinylacetat oder mit Mischungen aus Polyvinylacetatdispersionen und Synthese-oder Naturlatex oder mit Polyurethan.The pile threads are integrated into the base fabric of tufted floor coverings by means of a so-called primer with natural latex, synthetic latex e.g. based on butadiene styrene 40:60 or 60:40, with plastic dispersions, for example based on polyvinyl acetate or with mixtures of polyvinyl acetate dispersions and synthetic or natural latex or with polyurethane.

Bevorzugt sind Butadien-Styrol-Latex (ca. 50 %) z.B. im Verhältnis 40 : 60, 60 : 40 oder 35 : 60 + 3,5 Acrylsäure und Polyvinylacetat-Dispersionen (50 %ig), Mischpolymerisate von Vinylacetat mit Maleinsäuredibutylester z.B. im Verhältnis 77/23 (ca. 50 %ig), Mischpolymerisate von Styrol/Butyacrylat/Acrylnitril/Methacrylsäure/Acrylamid z.B. im Verhältnis 16 : 61 : 25 : 2 : 1 oder 25 : 53 : 25 : 2 : 1, Mischpolymerisate von Ethylacrylat/Acrylnitril/N-Methylacrylamid 6 : 3 : 1, Mischpolymerisate von Butylacrylat/Vinylacetat/N-Methylolacrylamid 35 : 55 : 10, ferner Pfropfpolymerisate (partiell verseift) wie 50 % Polyvinylalkohol, 25 % Polyvinylacetat, 25 % Polyethylen.Butadiene-styrene latex (approx. 50%) is preferred, e.g. in the ratio 40:60, 60:40 or 35:60 + 3.5 acrylic acid and polyvinyl acetate dispersions (50%), copolymers of vinyl acetate with maleic acid dibutyl ester e.g. in the ratio 77/23 (approx. 50%), copolymers of styrene / butyacrylate / acrylonitrile / methacrylic acid / acrylamide e.g. in the ratio 16: 61: 25: 2: 1 or 25: 53: 25: 2: 1, copolymers of ethyl acrylate / acrylonitrile / N-methyl acrylamide 6: 3: 1, copolymers of butyl acrylate / vinyl acetate / N-methylolacrylamide 35: 55: 10, furthermore graft polymers (partially saponified) such as 50% polyvinyl alcohol, 25% polyvinyl acetate, 25% polyethylene.

Der Vorstrich enthält darüberhinaus noch üblicherweise Verdicker und Kreide oder Aluminiumhydroxyd als Füllmittel. Der Auftrag dieses Vorstrichs auf den Teppichrücken erfolgt durch Pflatschen.The primer also usually contains thickeners and chalk or aluminum hydroxide as a filler. This primer is applied to the back of the carpet by splashing.

Auf diesen Vorstrich wird im allgemeinen noch eine Rückenbeschichtung aufgetragen, entweder ein Schaumstrich oder ein Deckstrich, der zum Verkleben eines textilen Zweitrückens dient. Die Applikation dieses Zweitstrichs erfolgt durch Rakelauftrag. Eine Verklebung des textilen Zweitrückens kann aber auch beim Auftrag des Vorstrichs erfolgen, wobei nach dem Pflatschauftrag des Vorstrichs der Zweitrücken von einer Anpreßwalze an die klebende, pigmentierte Latexdispersion geführt und angepreßt wird.A back coating is generally applied to this primer, either a foam coat or a top coat, which is used to glue a second textile back. This second stroke is applied by squeegee application. However, the textile backing can also be glued when the pre-coat is applied, with the second back being guided and pressed by a pressure roller onto the adhesive, pigmented latex dispersion after the pre-coat has been applied.

Es wurde nun gefunden, daß man sowohl die Einbindung der Polfäden in den Vorstrich als auch die Verklebung eines textilen Zweitrückens durch Zugabe von Fluortensiden zum Vorstrich oder zum Zweitstrich wesentlich verbessern kann.It has now been found that both the incorporation of the pile threads in the primer and the bonding of a textile backing can be significantly improved by adding fluorosurfactants to the primer or the second coat.

Gegenstand der Erfindung ist somit ein Verfahren zur Verbesserung der Gebrauchseigenschaften von Tufted-Bodenbelägen, das darin besteht, daß man bei der Herstellung der Tufted-Bodenbeläge die für den Vorstrich und/oder die für den Zweitstrich erforderlichen Dispersionen oder Latices vor ihrer Compoundierung mit einem Fluortensid der Formel

The invention thus relates to a method for improving the performance properties of tufted floor coverings, which consists in the fact that in the manufacture of the tufted floor coverings the dispersions or latices required for the primer coat and / or the second coat coat prior to their compounding with a fluorosurfactant of the formula

Bevorzugt sind solche Fluortenside, die aus einem Gemisch verschiedener Einzelverbindungen bestehen mit gleicher Bedeutung von R, aber unterschiedlicher Bedeutung von Rf. M hat insbesondere die Bedeutung von NH4 und M' von Na, wobei M bzw. M' als Kationen und die entsprechenden Sulfonsäurereste als Anionen vorliegen. Wesentlich für die Erfindung ist, daß das Fluortensid zunächst mit dem Latex oder der Dispersion separat vermischt wird, bevor aus dieser Mischung dann durch Zugabe der anderen Komponenten die Vorstrich- bzw. Zweitstrichmasse hergestellt wird. Das Fluortensid wird dem Latex oder der Dispersion für den Vorstrich in einer Menge von 0,1 bis 0,2 Gew-% zugegeben. Wird gleichzeitig ein textiler Zweitrücken kaschiert, beträgt die Menge an Fluortensid im Latex oder in der Dispersion für den Vorstrich 0,1 bis 0,5 Gew-%. Wird dieser textile Zweitrücken durch einen Zweitstrich mit dem Grundgewebe verklebt, so enthalten der Latex oder die Dispersion für diesen Zweitstrich 0,1 bis 0,3 Gew-% an Fluortensid.Preferred fluorosurfactants are those which consist of a mixture of different individual compounds with the same meaning of R, but different meaning of Rf. M has in particular the meaning of NH 4 and M 'of Na, where M and M' as cations and the corresponding sulfonic acid residues are present as anions. It is essential for the invention that the fluorosurfactant is first mixed separately with the latex or the dispersion before it is mixed then the primer or second coat mass is produced by adding the other components. The fluorosurfactant is added to the latex or the dispersion for the primer in an amount of 0.1 to 0.2% by weight. If a secondary textile backing is concealed at the same time, the amount of fluorosurfactant in the latex or in the dispersion for the primer is 0.1 to 0.5% by weight. If this textile backing is glued to the base fabric with a second coat, the latex or the dispersion for this second coat contain 0.1 to 0.3% by weight of fluorosurfactant.

Die Zusammensetzung von Vorstrich und Zweitstrich im einzelnen entspricht dem Stand der Technik auf diesem Gebiet, so daß Art und Menge der verschiedenen Komponenten nicht im einzelnen erörtert werden müssen, da sie dem Fachmann hinreichend bekannt sind. Typische Rezepturen für den Vorstrich enthalten z.B. 100 Teile Styrol-Butadien Latex oder Naturlatex, 200-400 Teile Kreide, 0,3 Teile Wasserenthärter, 2 Teile Verdicker auf Basis von Acrylaten oder Cellulosederivaten. Der Zweitstrich kann beispielsweise bestehen aus 100 Teilen Styrol-Butadien Latex (weich) oder Naturlatex und 150 Teilen Kreide oder Aluminiumhydroxid. Hinzu kommt dann noch das Fluortensid wie oben angegeben. Das Fluortensid kann entweder in den Vorstrich oder in den Zweitstrich eingebracht werden, man kann aber auch bei beiden Aufstrichmassen den Latex oder die Dispersion mit diesen Fluortensiden vermischen.The composition of the primer and second coat corresponds to the state of the art in this field, so that the type and amount of the various components need not be discussed in detail since they are sufficiently known to the person skilled in the art. Typical recipes for the primer contain e.g. 100 parts styrene-butadiene latex or natural latex, 200-400 parts chalk, 0.3 parts water softener, 2 parts thickener based on acrylates or cellulose derivatives. The second line can consist of 100 parts styrene-butadiene latex (soft) or natural latex and 150 parts chalk or aluminum hydroxide. Then there is the fluorosurfactant as stated above. The fluorosurfactant can be applied either in the primer or in the second coat, but you can also mix the latex or the dispersion with these fluorosurfactants in both spreads.

Durch die Zugabe der Fluortenside zum Latex oder zur Dispersion mit anschließender Kompoundierung erhöht sich die Noppeneinbindung der Polfäden, auch solcher aus hydrophoben Garnen, infolge verbesserter Penetration und Haftung. Bei Verklebung mit einem textilen Zweitrücken wird durch die Zugabe der Fluortenside die Haftfestigkeit des Rückens deutlich erhöht. Gleichzeitig wird die Schnittfestigkeit des Bodenbelags positiv beeinflußt und das Ausreißen von Flornoppen im Schnittbereich vermindert.By adding the fluorosurfactants to the latex or to the dispersion followed by compounding, the bobbin binding of the pile threads, including those made of hydrophobic yarns, increases as a result of improved penetration and adhesion. When gluing with a second textile back, the addition of the fluorosurfactants significantly increases the adhesive strength of the back. At the same time, the cut resistance of the floor covering is positively influenced and the tearing out of tufts in the cut area is reduced.
