Description

Schmutzabweisendes Ausrüstungsmittel enthaltendes MittelA soil repellent finish containing agent
Die Erfindung betrifft ein schmutzabweisendes Ausrüstungsmittel, wie bspw. Polysiloxan enthaltendes Mittel zur schmutzhemmenden Ausrüstung für textile Flächen, insbesondere textile Bodenflächen, ggf. als Bestandteil eines Teppich- Reinigungsmittels, wobei das Mittel weiter ein Netzmittel und / oder ein An- tistatikum enthält.The invention relates to a dirt-repellent finishing agent, such as. Polysiloxane-containing agent for soil-inhibiting equipment for textile surfaces, in particular textile floor surfaces, optionally as part of a carpet cleaning agent, wherein the agent further contains a wetting agent and / or an antistatic.
Schmutzabweisende Ausrüstungsmittel als Bestandteil von Mitteln zur schmutzhemmenden Ausrüstung von textilen Flächen sind bekannt. Diese basieren zumeist auf Fluorcarbonen. Auch fluoralkylfreie Produkte auf Basis von Polysiloxanen oder Polyacrylaten sind bekannt. In der EP 1 156 151 Bl ist ein Mittel zur schmutzhemmenden Ausrüstung für textile Flächen beschrieben, das ein Trägermaterial und eine Wirkstofflösung enthält, die als schmutzhemmen- de Substanz ein Fluorcarbonharz oder ein Polysiloxanderivat oder eine Kombination davon beinhaltet. Dieses Mittel dient zur schmutzhemmenden Ausrüstung textiler Flächen, insbesondere textiler Bodenbeläge, sowie deren Reinigung.Dirt-repellent finishes are known as part of antisoiling agents of textile surfaces. These are mostly based on fluorocarbons. Also fluoroalkyl-free products based on polysiloxanes or polyacrylates are known. EP 1 156 151 B1 describes an agent for dirt-inhibiting equipment for textile surfaces, which contains a carrier material and a solution of active substance which contains as a soil-inhibiting substance a fluorocarbon resin or a polysiloxane derivative or a combination thereof. This agent is used for the dirt-inhibiting equipment of textile surfaces, in particular textile floor coverings, as well as their cleaning.
Im Hinblick auf den zuvor beschriebenen Stand der Technik wird eine technische Problematik der Erfindung darin gesehen, ein Ausrüstungsmittel der in Rede stehenden Art derart verbessert weiterzubilden, dass bei gegenüber dem bekannten Stand der Technik gleichem Anteil von schmutzhemmendem Ausrüstungsmittel wie Polysiloxan in dem Reinigungsmittel eine Verbesserung der schmutzabweisenden Wirkung erreicht wird bzw. bei gegenüber dem Stand der Technik verringertem Anteil des Ausrüstungsmittels in dem Reinigungsmittel eine zumindest gleiche schmutzabweisende Wirkung erzielt wird.In view of the above-described prior art, a technical problem of the invention is seen in such a refinement of a device of the kind in question improved so that with respect to the prior art equal proportion of dirt-inhibiting finishing agent such as polysiloxane in the detergent an improvement in dirt-repellent effect is achieved or in comparison with the prior art reduced proportion of the finishing agent in the cleaning agent at least the same dirt-repellent effect is achieved.
Diese Problematik ist zunächst und im Wesentlichen durch den Gegenstand des Anspruches 1 gelöst, wobei darauf abgestellt ist, dass als Netzmittel und / oder Antistatikum ein kationisches Tensid eingesetzt ist. Da die Anfälligkeit textiler Beläge zu verschmutzen u.a. von den Oberflächeneigenschaften der Faser und von der Anfälligkeit zur elektrostatischen Aufladung abhängt, wird der Zusatz eines synergistisch wirkenden Netzmittels und Antistatikums vorgeschlagen. Als Netzmittel und Antistatikum findet ein kationisches Tensid Verwendung. Als kationische Tenside bezeichnet man Substanzen, die eine positiv geladene funktionelle Gruppe besitzen. Wie jedes Tensid sind auch die kationischen Tenside aus einem polaren und einem unpolaren Teil aufgebaut. Als unpolarer Teil dienen verschiedene Alkylreste. Die polare Gruppe ist in der Regel eine quar- ternäre Ammonium-Einheit. Durch die Verwendung eines Netzmittels in Form eines kationischen Tensids werden zumindest gleiche, sogar verbesserte schmutzabweisende Wirkungen gegenüber Reinigungsmitteln erzielt, die ein Polysiloxan bzw. ein anderes schmutzhemmendes Ausrüstungsmittel ohne ein solches vorgeschlagenes synergistisch wirkendes Netzmittel beinhalten. Dies selbst bei einer Einsparung von bis zu 50 % der schmutzhemmenden Ausrüstungsmenge. So kann bspw. bei einer Halbierung der Ausrüstungsmenge und einem Zusatz in Form eines kationischen Tensids eine verbesserte schmutzabweisende Wirkung in einer Größenordnung von 10 bis 30 % erreicht werden.This problem is solved first and foremost by the subject matter of claim 1, wherein it is pointed out that as a wetting agent and / or Antistatic a cationic surfactant is used. Since the susceptibility of soiling of textile coverings depends, inter alia, on the surface properties of the fiber and the susceptibility to electrostatic charging, the addition of a synergistically acting wetting agent and antistatic agent is proposed. The wetting agent and antistatic agent used is a cationic surfactant. Cationic surfactants are substances which have a positively charged functional group. Like any surfactant, the cationic surfactants are composed of a polar and a nonpolar part. As nonpolar part serve various alkyl radicals. The polar group is usually a quarternary ammonium unit. The use of a surfactant in the form of a cationic surfactant achieves at least equal, even improved, antisoiling effects over detergents that include a polysiloxane or other antisoiling finish without such a proposed synergistic wetting agent. This even with a saving of up to 50% of the dirt-inhibiting equipment amount. Thus, for example, when halving the amount of equipment and an additive in the form of a cationic surfactant improved dirt-repellent effect in the order of 10 to 30% can be achieved.
Die Gegenstände der weiteren Ansprüche sind nachstehend in Bezug zu dem Gegenstand des Anspruches 1 erläutert, können aber auch in ihrer unabhängigen Formulierung von Bedeutung sein.The subjects of the further claims are explained below in relation to the subject matter of claim 1, but may also be significant in their independent formulation.
In einer bevorzugten Ausgestaltung ist das kationische Tensid eine quarternäre Ammoniumverbindung, so bspw. Dodexyl- oder Hexadecyltrimethylammoni- umchlorid. Bezüglich des Ausrüstungsmittels kann alternativ zu einem Polysiloxan auch ein Ausrüstungsmittel auf Basis eines fluoralkylfreien Polyacrylats vorgesehen sein. In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass das Mittel, d.h. das auf die auszurüstende textile Fläche aufzubrin- gende Reinigungs- / Schmutzhemmungsmittel, 0,01 bis 10 Gew.-% Netzmittel aufweist, so weiter in einer bevorzugten Ausführung 0,25 - 1 Gew.-%. Versuche ergaben gute Ergebnisse hinsichtlich des Wiederanschmutzverhaltens bei einer Zugabe von 0,5 Gew.-% Netzmittel bzw. Antistatikum, dies weiter bevorzugt unter Halbierung der ursprünglichen Menge an Ausrüstungsmittel. Weiter kann vorgesehen sein, dass das Netzmittel mit einem Festkörpergehalt von 25 - 50 % vorliegt, so weiter beispielsweise 30 - 40 %, bevorzugt 36 %. Die Menge des Netzmittels entspricht in einer Weiterbildung des Erfindungsgegenstandes etwa dem 0,1- bis 1-Fachen der Menge des Ausrüstungsmittels. So ist beispielsweise bei einem 3%igen Polysiloxananteil 0,5 % Netzmittel vorgesehen, womit annähernd gleiche Wieder anschmutzungs werte erzielt werden, wie bei Mitteln, die einen doppelt hohen Anteil an Polysiloxan ohne Netzmittel in Form von kationischen Tensiden aufweisen. So erweist es sich entsprechend als vorteilhaft, wenn die Menge des Netzmittels einem Sechstel bis einem Drittel der Menge des Ausrüstungsmittels entspricht, so weiter bspw. etwa einem Zwan- zigstel bis einem Zehntel der Gesamtmenge des das Ausrüstungsmittel und das Netzmittel aufweisenden Auftragsmittels. Hierbei kann durch Halbierung der Ausrüstungsmenge unter Zusatz eines Netzmittels von etwa 10 - 20 % der schmutzhemmenden Ausrüstungsmenge eine um 10 - 30 % verbesserte schmutzabweisende Wirkung erreicht werden.In a preferred embodiment, the cationic surfactant is a quaternary ammonium compound, so for example Dodexyl- or Hexadecyltrimethylammoni- umchlorid. With regard to the finishing agent, as an alternative to a polysiloxane, a fining agent based on a fluoroalkyl-free polyacrylate may also be provided. In a preferred embodiment of the invention, it is provided that the agent, ie the cleaning / soil-inhibiting agent to be applied to the textile surface to be finished, contains 0.01 to 10% by weight wetting agent Thus, in a preferred embodiment, 0.25-1 wt%. Experiments have shown good resoiling performance with the addition of 0.5% by weight of wetting agent or antistatic agent, more preferably halving the original amount of finishing agent. It can further be provided that the wetting agent is present with a solids content of 25-50%, so on, for example, 30-40%, preferably 36%. The amount of wetting agent corresponds in a development of the subject invention about 0.1 to 1 times the amount of the finishing agent. Thus, for example, at a 3% polysiloxane content 0.5% wetting agent is provided, whereby approximately the same re-soiling values are achieved, as in the case of agents which have a doubly high content of polysiloxane without wetting agent in the form of cationic surfactants. Accordingly, it proves to be advantageous if the amount of the wetting agent corresponds to one sixth to one third of the amount of the finishing agent, so on, for example, about one-twentieth to one-tenth of the total amount of the application means comprising the finishing agent and the wetting agent. This can be achieved by halving the amount of equipment with the addition of a wetting agent of about 10 - 20% of the dirt-inhibiting equipment amount improved by 10 - 30% dirt-repellent effect.
Das erfindungsgemäße Mittel wird nachstehend anhand der beigefügten Zeichnungen, die lediglich Ausführungsbeispiele des Mittels wiederspiegeln, näher erläutert. Es zeigt:The agent according to the invention will be explained in more detail below with reference to the accompanying drawings, which merely illustrate embodiments of the agent. It shows:

Fig. 3 ein weiteres Balkendiagramm zur Darstellung der Wiederanschmut- zungshemmung im Vergleich zu einem unbehandelten Teppich bei Verwendung verschiedener schmutzhemmender Ausrüstungsmittel mit einem vorgeschlagenen Netzmittel im Vergleich zu den schmutz- hemmenden Ausrüstungsmitteln ohne Netzmittel.FIG. 3 is another bar graph illustrating resumption inhibition as compared to an untreated carpet using various antisoiling finishing agents with a proposed wetting agent as compared to antisoiling antisoiling equipments.
Die Bestimmung des Anschmutzverhaltens von neuen, erstmalig behandelten bzw. gereinigten Teppichen gibt Aufschluss darüber, wie ein Reinigungsmittel im Vergleich zu einem unbehandelten Teppich oder einem mit einem anderen Reinigungsmittel behandelten Teppich das Wiederanschmutzverhalten beein- flusst. Je nach Beschaffenheit des Reinigungsmittels kann eine erhöhte, neutrale oder verzögerte Anschmutzung bzw. Wiederanschmutzung erfolgen.The determination of the soiling behavior of new, initially treated or cleaned carpets provides information on how a cleaning agent influences the resoiling behavior in comparison to an untreated carpet or a carpet treated with another cleaning agent. Depending on the nature of the cleaning agent, increased, neutral or delayed soiling or re-soiling may occur.
Die Wiederanschmutzhemmung gibt hierbei an, ob ein Reinigungsmittel kom- biniert mit einem Ausrüstungsmittel die Teppichfasern so schützt, dass trockener Schmutz weniger am Teppichpol haftet und dieser deutlich geringer anschmutzt als bei einem unbehandelten Teppich.Resistance to sticking again indicates whether a cleaning agent combined with a finishing agent protects the carpet fibers in such a way that dry dirt adheres less to the carpet pile and contaminates it much less than with an untreated carpet.
Der mit einem Korrekturfaktor versehene Vergleich zu einer Standardrezeptur ohne schmutzhemmendem Ausrüstungsmittel mit neutralem Wiederanschmutzverhalten bezeichnet, ob eine Rezeptur eine stärkere (negativer Wert) oder geringere (positiver Wert) Wiederanschmutzung als diese Standardrezeptur zeigt. Entsprechend beschreibt eine große positive Differenz eine starke schmutzabweisende Wirkung. Ist die Differenz negativ, ist eine im Vergleich zur Referenzrezeptur stärkere Wiederanschmutzung erfolgt. Es wurde die Wiederanschmutzungshemmung eines Teppichreinigungsmittels mit unterschiedlichen Anteilen eines Polysiloxans (Ausrüstungsmittel A) im Vergleich zu einem Standard-Teppichreinigungsmittel ohne Ausrüstungsmittel ermittelt (vgl. Fig.l), um den Verlauf der Abhängigkeit zu bestimmen. Unterschiede ab 0,5 ΔE werden optisch wahrgenommen.The correction factor comparison to a standard non-stain neutralizer antisagging finish formulation indicates whether a recipe exhibits a stronger (negative value) or lower (positive value) stain than this standard formulation. Accordingly, a large positive difference describes a strong dirt-repellent effect. If the difference is negative, there is a stronger re-soiling compared to the reference recipe. The antiredeposition inhibition of a carpet cleaner having different proportions of a polysiloxane (Finishing Agent A) compared to a standard carpet cleaner without finishing agent was determined (see Fig. 1) to determine the course of the dependency. Differences from 0.5 ΔE are perceived optically.
Eine Rezeptur mit einem 44% igen Anteil an Ausrüstungsmittel A erreicht im Vergleich zu einer Standardrezeptur ohne Ausrüstungsmittel eine Wiederan- schmutzungshemmung von 4,7 ΔE. Entsprechend ist eine starke schmutzabweisende Wirkung erzielt. Eine lineare Abhängigkeit ist bis zu einem Anteil an Po- lysiloxan A bis 8 % mit einer Wiederanschmutzungshemmung von 3,2 ΔE gegeben.A formulation with a 44% level of finishing agent A has a resistance to staining of 4.7 ΔE compared to a standard formula without finishing. Accordingly, a strong dirt-repellent effect is achieved. A linear dependence is given up to a proportion of polysiloxane A to 8% with a Wiederanschmutzungshemmung of 3.2 ΔE.
Es erweist sich als vorteilhaft, eine möglichst geringe Menge an Ausrüstungsmitteln A einzusetzen. Durch die synergistische Wirkung einer Kombination aus Ausrüstungsmittel A und eines Netzmittels N und Antistatikums wird die Wiederanschmutzungshemmung verstärkt (vgl. Fig. 2). Wird das Netzmittel N und Antistatikum ohne Ausrüstungsmittel A in eine Rezeptur eingesetzt, wird bei l%igem (N) bzw. 4%igem (N') Zusatz eine Wiederanschmutzungshemmung von 1,1 bzw. 1,6 ΔE erreicht. Dies bedeutet, dass eine um den Faktor 4 erhöhte Konzentration lediglich eine geringe Erhöhung der Wirksamkeit um 0,5 ΔE bewirkt.It proves to be advantageous to use the smallest possible amount of finishing agent A. The synergistic effect of a combination of finishing agent A and a wetting agent N and antistatic enhances resistance to re-soiling (see Fig. 2). If the wetting agent N and antistatic agents without finishing agent A are used in a formulation, resistance to re-soiling of 1.1 or 1.6 ΔE is achieved with 1% (N) or 4% (N ') addition. This means that a concentration increased by a factor of 4 causes only a small increase in the activity by 0.5 ΔE.
Eine Rezeptur mit 6%igem Polysiloxananteil A weist eine Wiederanschmutzungshemmung von 2,3 ΔE auf. Durch eine Kombination AN" von 3 % PoIy si- loxan A mit 0,5 % des Netzmittels N und Antistatikums wird jedoch eine Wiederanschmutzungshemmung im annähernd gleichen Bereich, konkret von etwa 2,4 ΔE erreicht. Wird das Netzmittel N und Antistatikum l%ig zugesetzt, so verbessert sich die Wiederanschmutzungshemmung weiter auf 2,7 ΔE (Kombination AN). Entsprechend ist bei halbiertem Ausrüstungsmittel wie Polysiloxan unter Zugabe von 1 % des Netzmittels N eine weiter verbesserte schmutzabweisende Wirkung erreicht. Die Zugabe von 0,25 % Netzmittel N (Kombination AN') erbrachte keine verbesserte Wiederanschmutzhemmung.A formulation with 6% polysiloxane content A has a repellency inhibition of 2.3 ΔE. However, a combination of AN 3% polysiloxane A with 0.5% of the wetting agent N and antistatic achieves resistance to re-soiling in approximately the same range, specifically about 2.4 ΔE If the wetting agent N and antistatic agent become 1% added, so Residue inhibition further improves to 2.7 ΔE (combination AN). Accordingly, with halved finishing agent such as polysiloxane with the addition of 1% of the wetting agent N, a further improved soil-repellent effect is achieved. The addition of 0.25% wetting agent N (combination AN ') did not provide improved resoiling inhibition.
Alternativ können die Ausrüstungsmittel A auch auf Basis einer Perfluoralkyl- polyacrylatdispersion (A1) bzw. einer fluoralkylfreien, anionischen Polyacrylat- dispersion (A") gebildet sein. Mittels dieser Rezepturen wurde sowohl mit (Re- zepturen AN, A1N und A"N) als auch ohne Netzmittel und Antistatikum (Rezepturen A, A1, A") das jeweilige Wiederanschmutzungsverhalten bestimmt (vgl. Fig. 3). Der ΔE-Wert eines unbehandelten Teppichabschnitts wird als Referenzwert 100 % gesetzt und die Anschmutztiefen der weiteren Proben hierzu im Verhältnis gesetzt.Alternatively, the finishing agents A can also be formed on the basis of a perfluoroalkyl polyacrylate dispersion (A 1 ) or a fluoroalkyl-free, anionic polyacrylate dispersion (A ") which has been formulated with both (formulas AN, A 1 N and A). N) as well as without wetting agent and antistatic (formulations A, A 1 , A ") determines the respective resoiling behavior (see Fig. 3) .The ΔE value of an untreated carpet section is set as the reference value 100% and the soiling depths of the further samples thereto set in proportion.
Es ist aus dem Balkendiagramm in Fig. 3 zu erkennen, dass jeweils die l%ige Zugabe des Netzmittels N die Wirksamkeit der eingesetzten Ausrüstungsmittel A, A1, A" deutlich verstärkt, so bei den gezeigten Beispielrezepturen AN, A1N und A"N um 4 - 6 %.It can be seen from the bar diagram in FIG. 3 that in each case the 1% addition of the wetting agent N markedly enhances the effectiveness of the finishing agents A, A 1 , A "used, in the example formulations AN, A 1 N and A" shown. N by 4 - 6%.
Durch die vorgeschlagene Rezeptur mit 3 % Ausrüstungsmittel A, insbesondere Polysiloxan, und 0,5 % - 1 % Netzmittel N wird die Anzahl der Reinigungszyklen auf dem verwendeten Teppichboden um etwa die Hälfte reduziert.The proposed formulation with 3% finishing agent A, especially polysiloxane, and 0.5% -1% wetting agent N reduces the number of cleaning cycles on the carpet used by about half.
