Description

"Neutrale Selbstglanzemulsion zur Pflege von Fußböden (IV)" "Neutral self-gloss emulsion for the care of floors (IV)"
Die vorliegende Erfindung betrifft ein Mittel zur Pflege von Fußböden, das in Form einer Dispersion vorliegt und auf dem Fußboden selbstglänzend auf¬ trocknet. Derartige Mittel werden auch als Selbstglanzemulsionen bezeich¬ net.The present invention relates to an agent for the care of floors which is in the form of a dispersion and dries on the floor in a self-glossy manner. Such agents are also referred to as self-gloss emulsions.
Neue, bisher unbehandelte Fußböden und solche, die einer Grundreinigung unterzogen worden sind, werden heute zum Schutz vor Anschmutzungen und Beschädigungen ganz überwiegend mit Hilfe von Selbstglanzemulsionen ge¬ pflegt. Diese Mittel, die Wachs und/oder filmbildende Polymere in wechseln¬ der Zusammensetzung enthalten, bilden auf den Fußböden nach dem Abtrocknen geschlossene glänzende Filme aus, die schmutzabweisend wirken. Dabei kön¬ nen Filme, die einen hohen Wachsanteil aufweisen, leicht zusätzlich po¬ liert werden und sind bei Bedarf auch leicht wieder von den Oberflächen zu entfernen, während Filme, die überwiegend oder vollständig aus filmbil¬ denden Polymeren bestehen, besonders widerstandsfähig gegen mechanische Beanspruchung sind. Ein Problem, das bei allen Selbstglanzemulsionen bis heute nicht vollständig gelöst ist, liegt darin, daß die Emulsionen bzw. Dispersionen ganz gleichmäßig auf den Oberflächen eintrocknen müssen, wenn ein vollständig geschlossener Schutzfilm entstehen soll. Sehr häufig ist zu beobachten, daß der zunächst geschlossene Film der wäßrigen Dispersion beim Eintrocknen aufreißt und sich unter Umständen sogar zu einzelnen Tropfen zusammenzieht, so daß der entstehende Pflegefilm ein fleckiges Aussehen erhält. Besonders stark ist dieser Effekt bei den heute bevor¬ zugten Dispersionen mit weitgehend neutralem pH-Wert. Hier eine Verbes¬ serung zu schaffen, war eine der Aufgaben der vorliegenden Erfindung. Gleichzeitig sollte die Stabilität der Dispersionen, vor allem bei Lage¬ rung in der Kälte, verbessert werden. Gegenstand der Erfindung ist eine wäßrige Selbstglanzemulsion zur Pflege von Fußböden, die in unverdünntem Zustand einen pH-Wert zwischen 5 und 9 aufweist, und die ein natürliches oder synthetisches Wachs und einen Mono- alkyldiethylenglykolether mit 1 bis 4 C-Atomen im Alkylteil oder ein Ge¬ misch solcher Ether enthält. Besonders bevorzugt sind Selbstglanzemulsi¬ onen, deren pH-Wert im unverdünnten Zustand zwischen 6 und 8 liegt.New, previously untreated floors and those that have been subjected to basic cleaning are now predominantly maintained with the help of self-gloss emulsions for protection against soiling and damage. These agents, which contain wax and / or film-forming polymers in alternating compositions, form closed, glossy films on the floors after drying, which have a dirt-repellent effect. Films which have a high wax content can easily be additionally polished and, if necessary, can also be easily removed from the surfaces again, while films which consist predominantly or entirely of film-forming polymers are particularly resistant to mechanical stress are. A problem that has not yet been completely solved with all self-gloss emulsions is that the emulsions or dispersions have to dry completely uniformly on the surfaces if a completely closed protective film is to be formed. It can be observed very often that the initially closed film of the aqueous dispersion tears open when it dries up and may even contract into individual drops, so that the resulting care film has a spotty appearance. This effect is particularly strong in the presently preferred dispersions with a largely neutral pH. One of the objects of the present invention was to provide an improvement here. At the same time, the stability of the dispersions, particularly when stored in the cold, should be improved. The invention relates to an aqueous self-gloss emulsion for the care of floors, which has an undiluted pH of between 5 and 9, and which is a natural or synthetic wax and a monoalkyl diethylene glycol ether with 1 to 4 carbon atoms in the alkyl part or a Ge ¬ mix of such ethers. Self-gloss emulsions whose pH in the undiluted state is between 6 and 8 are particularly preferred.
Die neuen Selbstglanzemulsionen zeichnen sich durch hohe Lagerstabilität, insbesondere auch bei niedrigen Temperaturen, aus. Besonders bemerkenswert ist das außerordentlich gleichmäßige Antrockenverhalten, bei dem ein Auf¬ reißen des Films praktisch nicht zu beobachten ist, so daß gleichmäßige, optisch einwandfreie Pflegefilme resultieren. Weiterhin ist überraschend, daß die erfindungsgemäßen Mittel gegen ikrobiellen Befall stabil sind und deshalb auf den Zusatz von üblichen Konservierungsstoffen verzichtet wer¬ den kann.The new self-gloss emulsions are characterized by high storage stability, especially at low temperatures. Particularly noteworthy is the extremely uniform drying behavior, in which tearing of the film is practically not observable, so that uniform, optically perfect care films result. It is also surprising that the agents according to the invention are stable against microbial attack and therefore the addition of conventional preservatives can be dispensed with.
Als Wachse eignen sich für die erfindungsgemäßen Selbstglanzmittel sowohl natürliche Wachse als auch synthetische Wachse, die natürlichen Ursprungs aber auch vollsynthetisch hergestellt sein können. Beispiele sind Poly- ethylenwachse, oxidierte Polyethylenwachse, Montanesterwachse, Paraffin¬ wachse, Candellilawachs und Carnaubawachs. Von diesen werden in den er¬ findungsgemäßen Mitteln Montanesterwachs, Paraffinwachs, Carnaubawachs und Polyethylenwachs bevorzugt. Besonders bevorzugt werden Wachsmischungen aus Montanesterwachs und Polyethylenwachs sowie aus Montanesterwachs und Car¬ naubawachs. Der Gehalt an Wachs beträgt in den erfindungsemäßen Mitteln 2 bis 50 Gew.-%, vorzugsweise 2 bis 15 Gew.-%.Suitable waxes for the self-gloss agents according to the invention are both natural waxes and synthetic waxes, which, however, can also be produced entirely synthetically from natural origin. Examples are polyethylene waxes, oxidized polyethylene waxes, montan ester waxes, paraffin waxes, candellila wax and carnauba wax. Of these, montan ester wax, paraffin wax, carnauba wax and polyethylene wax are preferred in the agents according to the invention. Wax mixtures of montan ester wax and polyethylene wax and of montan ester wax and carnauba wax are particularly preferred. The wax content in the agents according to the invention is 2 to 50% by weight, preferably 2 to 15% by weight.
Sofern nicht überwiegend selbstemulgierende Wachse verwendet werden, ent¬ halten die erfindungsgemäßen Emulsionen übliche Wachsemulgatoren in Mengen zwischen 0,1 und 10 Gew.-%, vorzugsweise zwischen 0,5 und 3 Gew.-%. Bei¬ spiele derartiger Emulgatoren sind der mit 20 Mol Ethylenoxid (E0) ethoxy- lierte Oleylcetylalkohol und Sorbit onooleat.Unless predominantly self-emulsifying waxes are used, the emulsions according to the invention contain conventional wax emulsifiers in amounts between 0.1 and 10% by weight, preferably between 0.5 and 3% by weight. Examples of such emulsifiers are oleyl acetyl alcohol ethoxylated with 20 moles of ethylene oxide (E0) and sorbitol onooleate.
Bei dem zweiten kennzeichnenden Bestandteil der erfindungsgemäßen Selbst¬ glanzemulsion handelt es sich um einen Monoalkyldiethylenglykolether mit 1 bis 4 C-Atomen im Alkylteil, wobei selbstverständlich auch Gemische dieser Ether verwendet werden können. Bevorzugt werden Methyldiglykol, Ethyldi- glykol und n-Butyldiglykol verwendet. Die Ether scheinen im Zusammenwirken mit den Wachsen in der wäßrigen neutralen Emulsion für die oben geschil¬ derten unerwarteten Eigenschaften der neuen Mittel verantwortlich zu sein. Im allgemeinen reichen geringe Mengen dieser Ether aus. Ihr Anteil an den erfindungsgemäßen Mitteln beträgt 0,05 bis 11 Gew.-%, vorzugsweise 3 bis 8 Gew.-%.The second characteristic constituent of the self-gloss emulsion according to the invention is a monoalkyldiethylene glycol ether having 1 to 4 carbon atoms in the alkyl part, it also being possible, of course, to use mixtures of these ethers. Methyl diglycol, ethyl di glycol and n-butyl diglycol are used. In conjunction with the waxes in the aqueous neutral emulsion, the ethers seem to be responsible for the unexpected properties of the new agents described above. In general, small amounts of these ethers are sufficient. Their proportion of the agents according to the invention is 0.05 to 11% by weight, preferably 3 to 8% by weight.
Neben den obengenannten Wachsen, die den überwiegenden Teil der Feststoffe im erfindungsgemäßen Mittel ausmachen, können die Mittel filmbildende Poly¬ mere in dispergierter Form enthalten. Der Polymeranteil dient dazu, die Pflegefilme widerstandsfähiger gegen mechanische Beschädigung zu machen. Bei diesen Polymerverbindungen handelt es sich um solche, die in Wasser bei neutralem pH-Wert wenigstens teilweise unlöslich sind und die eine minimale Filmbildetemperatur im Bereich zwischen etwa 0 und etwa 70 C° aufweisen. Es handelt sich dabei vorzugsweise um Polymere, die aus ethy- lenisch ungesättigten Monomeren hergestellt werden. Beispiele derartiger Monomerer sind Styrol, Acrylsäureester oder Methacrylsäureester alipha- tischer, 1 bis 8 C-Atome aufweisender Alkohole, Acrylnitril, Vinylacetat, Acrylsäure und Methacrylsäure. Besonders bevorzugt werden Poly(meth)acry- late aus zwei oder mehr dieser Monomeren, die gegebenenfalls in untergeord¬ neter Menge auch weitere Mono ere enthalten können. Ganz besonders bevor¬ zugte Polymere enthalten 1 bis 30 Gew.-Teile an carbonsäuregruppenhaltigen Monomeren, 30 bis 70 Gew.-Teile Monomere, die Homopolymere mit Glastempe¬ raturen unter 20 °C bilden, vorzugsweise Ester der Acrylsäure mit Ci-Cs- Alkoholen und/oder der Methacrylsäure mit C4-C8-Alkoholen und 30 bis 70 Gew.-Teile Monomere, die Homopolymere mit Glastemperaturen über Raumtem¬ peratur bilden, vorzugsweise Methacrylsäureester von Cι~C3-Alkoholen oder Styrol. Werden mehrere unterschiedliche Polymerverbindungen der vorstehend genannten Art im Gemisch eingesetzt, soll die Filmbildetemperatur, die für das Gemisch ermittelt wird, im Bereich zwischen 0 und 70 °C liegen. Die genannten Filmbildungstemperaturen beziehen sich auf das weichmacherfreie System, d. h. auf die Polymeren ohne weitere Zusätze.In addition to the waxes mentioned above, which make up the majority of the solids in the agent according to the invention, the agents can contain film-forming polymers in dispersed form. The polymer content serves to make the care films more resistant to mechanical damage. These polymer compounds are those which are at least partially insoluble in water at neutral pH and which have a minimum film-forming temperature in the range between about 0 and about 70 ° C. These are preferably polymers which are produced from ethylenically unsaturated monomers. Examples of such monomers are styrene, acrylic acid ester or methacrylic acid ester of aliphatic alcohols having 1 to 8 carbon atoms, acrylonitrile, vinyl acetate, acrylic acid and methacrylic acid. Poly (meth) acrylates from two or more of these monomers are particularly preferred, which may also contain further monomers in a subordinate amount. Very particularly preferred polymers contain 1 to 30 parts by weight of monomers containing carboxylic acid groups, 30 to 70 parts by weight of monomers which form homopolymers with glass temperatures below 20 ° C., preferably esters of acrylic acid with Ci-Cs alcohols and / or methacrylic acid with C4-C8 alcohols and 30 to 70 parts by weight of monomers which form homopolymers with glass transition temperatures above room temperature, preferably methacrylic acid esters of -C3-alcohols or styrene. If several different polymer compounds of the type mentioned above are used in the mixture, the film-forming temperature which is determined for the mixture should be in the range between 0 and 70.degree. The film formation temperatures mentioned relate to the plasticizer-free system, i. H. on the polymers without further additives.
Die Polymeren können in den erfindungsgemäßen Mitteln in Mengen bis zu 30 Gew.-% , insbesondere zwischen 2 und 10 Gew.-% enthalten sein. Diese Zahlenangaben beziehen sich auf die reinen Polymeren. Wird bei der Her- Stellung der erfindungsgemäßen Suspensionen von dispergierten Polymeren ausgegangen, so wie sie vielfach im Handel angeboten werden, sind von die¬ sen Dispersionen entsprechend höhere Mengen bei der Herstellung der er¬ findungsgemäßen Mittel zu verwenden.The polymers according to the invention can be present in amounts of up to 30% by weight, in particular between 2 and 10% by weight. These figures refer to the pure polymers. Is used in the If the suspensions according to the invention are based on dispersed polymers, as are often offered commercially, correspondingly higher amounts of these dispersions are to be used in the preparation of the compositions according to the invention.
Neben den vorstehend genannten Inhaltsstoffen können die erfindungsgemäßen Selbstglanzemulsionen weitere Wirk- und Hilfsstoffe in geringeren Mengen enthalten, sofern sie die positiven Eigenschaften der Mittel nicht beein¬ trächtigen. Als Beispiele seien Weichmacher, Netz- und Verlaufshilfsmittel, Netzharze und Parfümöle genannt.In addition to the ingredients mentioned above, the self-gloss emulsions according to the invention can contain other active ingredients and auxiliaries in smaller amounts, provided that they do not impair the positive properties of the agents. Examples include plasticizers, wetting and leveling agents, network resins and perfume oils.
Weichmacher dienen zur Modifizierung der Filmkonsistenz, wobei man zwi¬ schen temporären Weichmachern und permanenten Weichmachern unterscheidet. Bei den temporären Weichmachern handelt es sich um flüchtige hydrophile Lösungsmittel, die das Zusammenlaufen der Polymerteilchen bei der Film¬ bildung begünstigen. Beispiele sind Ethylenglykol, Diethylenglykol sowie Glykolether. Ihr Anteil an den erfindungsgemäßen Mitteln liegt im allge¬ meinen nicht über 15 Gew.-%, vorzugsweise zwischen 0,5 und 10 Gew.-%. Per¬ manente Weichmacher sind Flüssigkeiten, die unter Normalbedingungen nicht flüchtig sind, so daß mit deren Hilfe die Beschaffenheit des Pflegefilms anhaltend beeinflußt werden kann. Beispiele derartiger Weichmacher sind Dibutylphthalat, Tributylphosphat, Tributoxyethylphosphat und N-Methyl- caprolactam. Auch dieser Weichmachertyp ist in den erfindungsgemäßen Sus¬ pensionen im allgemeinen zu nicht mehr als 15 Gew.-% enthalten. Bevorzugt wird ein Gehalt an 0,5 bis 10 Gew.-%.Plasticizers serve to modify the film consistency, a distinction being made between temporary plasticizers and permanent plasticizers. The temporary plasticizers are volatile, hydrophilic solvents which promote the convergence of the polymer particles during film formation. Examples are ethylene glycol, diethylene glycol and glycol ether. Their proportion of the agents according to the invention is generally not more than 15% by weight, preferably between 0.5 and 10% by weight. Permanent plasticizers are liquids which are not volatile under normal conditions, so that the condition of the care film can be influenced with their help. Examples of such plasticizers are dibutyl phthalate, tributyl phosphate, tributoxyethyl phosphate and N-methylcaprolactam. This type of plasticizer is generally not more than 15% by weight in the suspensions according to the invention. A content of 0.5 to 10% by weight is preferred.
Netz- und Verlaufshilfsmittel dienen dazu, die Benetzung der behandelten Oberfläche beim Auftrag der Selbstglanzemulsion zu verbessern; außerdem wird dadurch die Verdünnung der Mittel mit Wasser, beispielsweise beim Auftragen auf feuchte Fußböden, erleichert. Verwendbar sind die üblichen Tenside, insbesondere nichtionische und anionische Tenside, beispielsweise Ethoxylate von langkettigen Alkoholen oder Alkylbenzolsulfonate und Fett¬ alkoholsulfate. Sehr häufig werden hier auch Fluortenside verwendet, die eine besonders starke Erniedrigung der Grenzflächenspannung bewirken. Der Gehalt an Netz- und Verlaufshilfsmitteln liegt im allgemeinen nicht über 5 Gew.-%, bezogen auf das Gesamtgewicht der Selbstglanzemulsion. Vorzugs- weise liegt der Gehalt zwischen 0,1 und 2 Gew.-%. Auch mit Hilfe von Netz¬ harzen kann die Benetzung der Oberfläche beim Auftrag verbessert werden. Bei diesen Harzen handelt es sich beispielsweise um Styrol-Maleinatharze oder um klargestellte Polyacrylate. Ihr Gehalt in den Mitteln liegt im allgemeinen nicht über 5 Gew.-%; vorzugsweise werden zwischen 0,1 und 2 Gew.-% eingesetzt.Wetting agents and leveling agents serve to improve the wetting of the treated surface when the self-gloss emulsion is applied; it also makes it easier to dilute the agents with water, for example when applied to damp floors. The usual surfactants, in particular nonionic and anionic surfactants, for example ethoxylates of long-chain alcohols or alkylbenzenesulfonates and fatty alcohol sulfates, can be used. Fluorosurfactants, which bring about a particularly strong reduction in the interfacial tension, are also very often used here. The content of wetting and leveling agents is generally not more than 5% by weight, based on the total weight of the self-gloss emulsion. Preferred the content is between 0.1 and 2% by weight. The wetting of the surface during application can also be improved with the aid of mesh resins. These resins are, for example, styrene-maleate resins or clarified polyacrylates. Their content in the compositions is generally not more than 5% by weight; preferably between 0.1 and 2% by weight are used.
Die Herstellung der Mittel kann nach üblichen Suspendierverfahren erfol¬ gen. So kann man beispielsweise nach der Wasser-in-Wachs-Methode oder nach der Wachs-in-Wasser-Methode arbeiten. Der pH-Wert wird gegebenenfalls mit Alkalien oder Säuren auf den gewünschten Wert im neutralen pH-Bereich (pH 5 bis pH 9) eingestellt.The agents can be prepared by customary suspension processes. For example, the water-in-wax method or the wax-in-water method can be used. If necessary, the pH is adjusted to the desired value in the neutral pH range (pH 5 to pH 9) with alkalis or acids.
Die Anwendung der erfindungsgemäßen Selbstglanzemulsionen erfolgt in der Regel unverdünnt: Die Emulsionen werden auf die Oberfläche aufgetragen und dort mit Hilfe eines weichen Gegenstandes, beispielsweise eines Schwamms oder eines Lappens, gleichmäßig in der gewünschten Menge verteilt. Nach dem Verdunsten des Wassers verbleibt bei diesem Pflegeverfahren ein außer¬ ordentlich gleichmäßiger glänzender Pflegefilm. The self-gloss emulsions according to the invention are generally used undiluted: the emulsions are applied to the surface and distributed there in the desired amount with the aid of a soft object, for example a sponge or a cloth. After the water has evaporated, an extraordinarily uniform, glossy care film remains in this care process.

Während dieser Zeit wurden die Proben wöchentlich aus dem Gefrierschrank genommen und nach Erreichen der Raumtemperatur visuell beurteilt. Sichtbare Zeichen der Instabilität waren Ausflockungen, Boden¬ satz, Aufschwemmungen und Änderung der Viskosität. Die Bewertung wurde nach folgendem Maßstab vorgenommen:To assess the cold stability, the samples were stored at 0 - 3 ° C for 12 weeks. During this time, the samples were removed from the freezer weekly and assessed visually after reaching room temperature. Visible signs of instability were flocculation, sedimentation, flooding and changes in viscosity. The evaluation was carried out on the following scale:
0 einheitliche, homogene Probe0 uniform, homogeneous sample
1 leichte Aufschwemmungen oder Bodensatz nach 12 Wochen1 slight flooding or sediment after 12 weeks
2 leichte Aufschwemmungen oder Bodensatz nach 3 Wochen2 light suspensions or sediment after 3 weeks
3 mittlere Aufschwemmung oder Bodensatz nach 3 Wochen3 medium suspension or sediment after 3 weeks
4 starke Aufschwemmungen oder Bodensatz nach 3 Wochen4 heavy swellings or sediment after 3 weeks
5 sehr starke Aufschwemmungen oder Bodensatz nach 3 Wochen5 very strong floods or sediment after 3 weeks
Die Verlaufseigenschaften wurden durch praxisgerechte Anwendung auf schwar¬ zen, unbehandelten PVC-Bahnen ermittelt. Dazu wurden je Prüfvorgang 10 ml der zu prüfenden Suspension mit Hilfe eines Handauftraggerätes auf eine 30 x 60 cm große PVC-Platte gleichmäßig verteilt. Das Auftragsgerät bestand aus einem, auf einen Rahmen gespannten Polstervelourstoff, dessen wirksame Fläche 20 x 55 cm betrug. Nach dem Abtrocknen wurde das Aussehen der Ober¬ fläche visuell nach folgender Skala beurteilt:The flow properties were determined by practical application on black, untreated PVC sheets. For this purpose, 10 ml of the suspension to be tested were evenly distributed onto a 30 x 60 cm PVC plate using a hand-held applicator. The application device consisted of an upholstery fabric stretched on a frame, the effective area of which was 20 x 55 cm. After drying, the appearance of the surface was assessed visually on the following scale:
0 streifenfrei0 streak-free
1 schwach sichtbare gleichförmige Streifen1 weakly visible uniform stripe
2 deutlich sichtbare Streifen 3 deutl ich ungleichförmige Streifen2 clearly visible stripes 3 I see uneven stripes
4 starke unregelmäßige Rückstände4 large irregular residues

Aus den Prüfergebnissen werden die vorteilhafte Eigenschaften der erfin¬ dungsgemäßen Selbstglanzemulsion 2 gegenüber dem Vergleichsbeispiel 1 deut¬ lich. From the test results, the advantageous properties of the self-gloss emulsion 2 according to the invention compared to comparative example 1 are clear.
