Description

Die vorliegende Erfindung betrifft ein wäßriges Mittel zum Reinigen von harten Oberflächen, das eine Kombination aus im alkalischen Medium löslichen Polymerverbindungen und nichtionischen Tensiden enthält, sowie die Verwendung dieser Mittel zur maschinellen Reinigung von Fußböden.The present invention relates to an aqueous agent for cleaning hard Surfaces that are a combination of soluble in the alkaline medium Contains polymer compounds and nonionic surfactants, as well as the use these agents for machine cleaning of floors.

Auf dem Gebiet der Reinigung von harten Oberflächen sind neben den hygienischen und ästhetischen Aspekten die Materialien der zu reinigenden Oberflächen sowie die Art und Intensität der Verschmutzung sowie wirtschaftliche Faktoren zu berücksichtigen. Zu den harten Oberflächen zählen beispielsweise Beläge aus Natursteinen, Fliesen, wie Feinsteinzeugfliesen, aber auch elastische Beläge wie Linoleum und PVC. Bei der Reinigung von harten Oberflächen im gewerblichen Bereich ist zusätzlich zu berücksichtigen, daß die Oberflächen unterschiedliche Strukturen aufweisen und zugleich Verschmutzungen unterschiedlichster Art zu entfernen sind, ggf. je nach Anwendungszweck mit gleichzeitiger Desinfektion. Deshalb ist auch für diesen Bereich eine Vielzahl von Mitteln entwickelt worden.In the field of cleaning hard surfaces, besides hygienic and aesthetic aspects the materials of the surfaces to be cleaned as well as the type and Pollution intensity as well as economic factors. To the hard surfaces include, for example, coverings made of natural stones, tiles, such as Porcelain stoneware tiles, but also elastic coverings such as linoleum and PVC. In the Cleaning hard surfaces in the commercial sector must also be taken into account, that the surfaces have different structures and at the same time Various types of soiling have to be removed, depending on the situation Application with simultaneous disinfection. That is why for this area too a variety of means have been developed.

In der Praxis wird die Auswahl der Mittel im Wesentlichen dadurch bestimmt, ob die Mittel die Reinigungsaufgabe in möglichst kurzer Zeit auf den unterschiedlichsten Materialien unabhängig von der Verschmutzungsart materialschonend erfüllen. Aus wirtschaftlichen Gründen werden hierfür in der gewerblichen Reinigung Maschinen eingesetzt. Bei der Fußbodenreinigung verwendet man in der Regel Scheuersaugmaschinen (Reinigungsautomaten) oder Schrubb-Maschinen (Einscheibenoder kontrarotierende Mehrscheibenmaschinen bzw. Bürstenwalzmaschinen). Im letzteren Fall wird das Absaugen der Reinigungsmittel In einem zweiten Arbeitsgang mit einem Wassersauger ausgeführt.In practice, the choice of funds is essentially determined by whether the Means the cleaning task in the shortest possible time on the most varied Fill materials gently regardless of the type of contamination. Out For commercial reasons, machines are used in commercial cleaning used. Floor cleaning is usually used Scrubber driers (automatic cleaning machines) or scrubbing machines (single disc or contrasting multi-disc machines or brush rolling machines). in the the latter case involves vacuuming the cleaning agent in a second step running a water vacuum.

Bei der Reinigung von Fußböden mit rauhen Oberflächen, z.B. Steinzeug- oder Steingutplatten sowie nicht polierten Natur- und Kunststeinen, besteht das Problem, daß sich auf diesen Böden aufgrund der großen Oberfläche der Schmutz sehr schnell ablagert. When cleaning floors with rough surfaces, e.g. Stoneware or earthenware slabs as well as unpolished natural and artificial stones, there is the problem that on due to the large surface area, the dirt deposits very quickly.

Werden nur Reinigungsmittel angewendet, so sind die Oberflächen schon nach kürzester Zeit stark verschmutzt. Um die Ablagerung von erneuter Anschmutzung zu verzögern, erfolgt die Reinigung in der Regel in zwei Arbeitsgängen, nämlich die Reinigung als solche und eine anschließende Konservierung der Belagoberfläche. Produkte, die sowohl Reinigungs- als auch Pflegemittel enthalten, zeigen keine ausreichende Reinigungsleistung, so daß ein kontinuierlicher Schmutzaufbau erfolgt.If only cleaning agents are used, the surfaces are already after very dirty in no time. To prevent the deposition of renewed soiling delay, the cleaning is usually done in two steps, namely the Cleaning as such and subsequent preservation of the surface of the covering. Products that contain both cleaning and care products do not show any sufficient cleaning performance so that dirt builds up continuously.

Im Handel sind zwar auch Mischprodukte bekannt, die eine bessere Reinigungsleistung zeigen, diese Produkte schäumen jedoch so stark, das sie für die maschinelle Anwendung nicht geeignet sind. Hinzu kommt, daß die Wischpflegemittel häufig Pflegekomponenten enthalten, die einen starken Pflegefilm bilden, so daß trotz starken Absaugens bei der maschinellen Reinigung die Trittsicherheit von Feinsteinzeugfliesen beeinträchtigt werden kann. Weitere Versuche, reinigungsverstärkte kombinierte Produkte zu entwickeln, führen wegen des ungünstigen Schaumverhaltens häufig zu Problemen bei der maschinellen Anwendung. Außerdem führt ein höherer Tensidanteil zu klebrigen Rückständen auf den Böden, die wiederum eine intensivere Anschmutzung des Bodens zur Folge haben.Mixed products are known in the trade, which have a better cleaning performance show, however, these products foam so strongly that they are suitable for machine Application are not suitable. In addition, the wiping agents are common Contain care components that form a strong care film, so that despite strong Vacuuming the mechanical safety of porcelain stoneware tiles can be affected. Further attempts to combine cleaning enhanced Developing products often leads to the unfavorable foaming behavior Machine application problems. In addition, a higher proportion of surfactants sticky residues on the floors, which in turn causes more intensive soiling of the soil.

Auf der anderen Seite ist die Löslichkeit von filmbildenden Substanzen nur begrenzt, so daß sie sich nicht vollständig lösen und bei der nächsten Reinigung nicht bzw. nur unvollständig wieder entfernt werden können, so daß es zum Aufbau eines starken Pflegefilms kommen kann. Dieser beeinträchtigt wiederum die Trittsicherheit und das optische Aussehen des Bodens und macht in gewissen Abständen eine Sonderreinigung erforderlich.On the other hand, the solubility of film-forming substances is only limited, so that they will not come off completely and not or only during the next cleaning can be removed incompletely, so that it builds a strong Care film can come. This in turn affects the surefootedness and that visual appearance of the floor and does special cleaning at certain intervals required.

Der vorliegenden Erfindung lag somit die Aufgabe zugrunde, die herkömmlichen Reinigungsmittel zu verbessern und dabei Reinigungsmittel für harte Oberflächen, insbesondere für den gewerblichen Bereich, zu entwickeln, die eine gute Reinigungsleistung zeigen und gleichzeitig die Oberfläche konservieren, so daß die Reinigung in einem Arbeitsvorgang und vorzugsweise mit Reinigungsautomaten durchgeführt werden kann.The present invention was therefore based on the object, the conventional cleaning agents to improve and thereby cleaning agents for hard surfaces, especially for the commercial sector, to develop a good cleaning performance show and at the same time preserve the surface so that the Cleaning in one operation and preferably with automatic cleaning machines can be carried out.

    Die erfindungsgemäßen Mittel werden vorzugsweise in Verdünnung mit Wasser eingesetzt, wobei die Anwendungskonzentration meist zwischen 0,5 und 5 Gew.-%, vorzugsweise zwischen 2 und 5 Gew.-%, bezogen auf die Anwendungslösung, liegt. Die Anwendung kann manuell oder in üblichen Reinigungsautomaten erfolgen, beispielsweise durch Aufbringen der Reinigungslösung und anschließendes maschinelles Schrubben mit Scheuersaug- oder anderen Schrubbmaschinen. Der angelöste Schmutz ist gut in der Reinigerflotte dispergiert, so daß er sich nicht wieder in die Poren des Bodenmaterials ablagert, bevor die Flotte abgesaugt wird. Nach dem Schrubb- Saugprozeß wird der Boden nicht nachgespült, die verbleibende Restfeuchte trocknet an. Es bildet sich ein hauchdünner Pflegefilm auf der Oberfläche, der das Anhaften von Schmutz verhindert beziehungsweise vermindert. Dieser Pflegefilm wird beim nächsten Reinigungsvorgang vollständig wieder aufgelöst und bildet sich erneut aus der wiederum verbleibenden Restfeuchte.The agents according to the invention are preferably diluted with water used, the application concentration usually between 0.5 and 5 wt .-%, preferably between 2 and 5 wt .-%, based on the application solution.

Die geringe Filmdicke und die Beschaffenheit des Films gewährleisten ferner, daß die Trittsicherheit der Fliesen sichergestellt ist.When using the cleaning agent according to the invention in the cleaning of There is no build-up of the care film on the surfaces, as it is cleaned again when cleaned completely resolved. Ensure the low film thickness and the nature of the film furthermore that the sure-footedness of the tiles is ensured.

    Prüfung der ReinigungswirkungTesting the cleaning effect

    Die Reinigungswirkung der Wischpflegemittel wurde mit Hilfe eines Gardner-Waschbarkeits- und Scheuerprüfgerätes ermittelt, wie es in den Qualitätsnormen des Industrieverbandes Putz- und Pflegemittel e.V. beschrieben ist (Seife-Öle-Fette-Wachse, 108, Seiten 526-528 (1982)). Bei dieser Methode wird eine weiße PVC-Folie mit einer Testanschmutzung aus Ruß und Fett versehen und unter standardisierten Bedingungen mit einem mit dem Reinigungsmittel getränkten Schwamm maschinell gewischt. Die Reinigungsleistung wird durch photoelektrische Bestimmung des Remissionsgrades gemessen.The cleaning effect of the wiping care products was checked with the help of a Gardner washability and abrasion tester as determined in the quality standards of the industrial association Putz- und Pflegemittel e.V. is described (soap-oil-fat-waxes, 108, pages 526-528 (1982)). This method uses a white PVC film with a test soiling made of soot and fat and under standardized conditions with a the sponge soaked in the cleaning agent is wiped mechanically. The Cleaning performance is determined by photoelectric determination of the reflectance measured.

    Prüfung der PflegeeinwirkungChecking the effects of care

    Die Pflegewirkung zeigt sich unter anderem darin, daß durch einen aus früheren Behandlungen mit demselben Mittel stammenden Film die Ablösung von nachträglich aufgebrachten Anschmutzungen erleichtert wird.
    Das oben angegebene Prüfverfahren wurde deshalb in der Weise modifiziert, daß die Folie vor dem Aufbringen der gleichen Anschmutzung mit dem zu prüfenden Wischpflegemittel gewischt und dann getrocknet wurde. Nach dem Aufbringen der Anschmutzung erfolgte die Prüfung dann wie die Prüfung der Reinigungsleistung:    The care effect is shown, among other things, by the fact that a film from previous treatments with the same agent facilitates the detachment of subsequently applied soiling.
    The test method specified above was therefore modified in such a way that the film was wiped with the wiping agent to be tested and then dried before the same stain was applied. After applying the soiling, the test was then carried out like the cleaning performance:

    Tabelle 3 gibt die Ergebnisse der Prüfungen an allen 12 Mitteln wieder. Sie sind in Prozent Lichtremission bezogen auf weiß = 100 % angegeben. In allen Prüfungen wurden die Mittel in mit Wasser verdünnter Form mit einer Konzentration von 2 Gewichtsprozent angewendet. Table 3 shows the results of the tests on all 12 means. They are given in percent light emission based on white = 100%. In all tests, the agents were used in water-diluted form with a concentration of 2 percent by weight.

    Aus den Ergebnissen wird deutlich, daß die erfindungsgemäßen Wischpflegemittel 1 bis 6 eine ausgezeichnete Reinigungsleistung sowohl gegenüber nicht vorbehandelter als auch gegenüber vorbehandelter Folie aufweisen. Von vorbehandelter Folie wird dabei die Anschmutzung noch besser entfernt als von der ursprünglichen Folie. Die zum Vergleich herangezogenen Mittel R1-R3/P1-P3 zeigen dagegen gute Reinigungsleistungen entweder nur an unvorbehandelter Folie (6) oder nur an vorbehandelter Folie. Die nicht erfindungsgemäßen Mittel sind dabei in ihrer Pflegewirkung durchaus mit den erfindungsgemäßen Mitteln vergleichbar, führen aber anders als diese, nach mehrfacher Anwendung zu einer Filmaddition, die das natürliche Aussehen und die Trittsicherheit der behandelten Flächen beeinträchtigen.From the results it is clear that the wiping agents 1 to 6 Excellent cleaning performance over both non-pretreated and also have compared to pretreated film. The pretreated film is used the dirt is removed even better than from the original film. The for By comparison, means R1-R3 / P1-P3 used show good ones Cleaning services either only on untreated film (6) or only on pretreated film. The agents not according to the invention are in their care effect quite comparable to the agents according to the invention, but perform differently than these, after multiple application to a film addition, the natural look and the Impair the sure-footedness of the treated surfaces.

    Prüfung der WiederanschmutzungRe-contamination check

    Zur Bestimmung der Wiederanschmutzung wurden Felder von 0,5 bis 1 lfd. Meter Feinsteinzeugfliesen dreimal mit 5 %-iger Produktlösung mit einem gesättigten 15x15 cm Textil gewischt. Die Oberfläche wurde nicht nachgewischt.
    Nach dem Abtrocknen wurden die Felder einer natürlichen Begehung ausgesetzt. Die Anordnung der Prüffelder wurde täglich verändert. Die Bewertung der Prüffelder erfolgte durch Abmusterung mit einem nicht begangenen Prüffeld.
    Die Prüfdauer betrug 5 Tage bei täglicher Abmusterung und anschließender Reinigung mit 5 %-iger Produktlösung. Die Bewertung erfolgte nach folgendem Schlüssel.

  • 0 = wie Original
  • - = schlechtere Ergebnisse
    • To determine the re-soiling, fields from 0.5 to 1 running meter of porcelain stoneware tiles were wiped three times with 5% product solution with a saturated 15x15 cm textile. The surface was not wiped off.
    After drying, the fields were exposed to natural inspection. The arrangement of the test fields was changed daily. The test fields were evaluated by means of a test with a test field that was not used.
    The test duration was 5 days with daily sampling and subsequent cleaning with 5% product solution. The evaluation was based on the following key.
  • 0 = like original
  • - = worse results

    • Messung der TrittsicherheitSurefootedness measurement

    Die Messung erfolgte mit dem Gerät Floor Slide Control FSC 2000, Sellmaier Elektronic Vertrieb GmbH, Walsertalstr. 4, 81476 München.The measurement was carried out using the Floor Slide Control FSC 2000, Sellmaier Electronic Vertrieb GmbH, Walsertalstr. 4, 81476 Munich.

    Gemessen wurde die Gleitreibung. Es wurde mit einem neutralen Gleitmedium (standardisiertes Filterpapier) gemessen.The sliding friction was measured. It was made with a neutral lubricant (standardized filter paper) measured.

    Die in Tabelle 3 aufgeführten Gleitreibungswerte stellen einen Mittelwert aus 10 Messungen dar.The sliding friction values listed in Table 3 represent an average of 10 Measurements.

    Der Gleitreibungswert von 0,650 stellt den Originalbelag dar. Je niedriger der Gleitreibungswert, desto rutschiger ist die Oberfläche.The sliding friction value of 0.650 represents the original covering. The lower the sliding friction value, the slippery the surface.

    Prüfung des SchaumverhaltenTesting the foam behavior

    Schaumzaht/Schaumzerfall Schaumzaht / foam collapse

    Verfahren:Method:

    50 ml einer 1 %-igen Lösung wurden in einen 250-ml Schüttelzylinder gegeben, der anschließend mit einem Stopfen verschlossen. Innerhalb von 20 Sekunden wurde der Zylinder 10mal um 180° gekippt und wieder aufgerichtet. Unmittelbar nach der letzten Kippbewegung wurde die Schaummenge abgelesen. Dann ließ man Schüttelzylinder ruhig stehen und nach 60 Sekunden wurde nochmals die Schaummenge abgelesen. Von den abgelesenen Werten wurden jeweils 50 ml für die vorgegebene Lösung abgezogen.50 ml of a 1% solution was placed in a 250 ml shaking cylinder, which was then closed with a stopper. Within 20 seconds the Cylinder tilted 10 times by 180 ° and erected again. Immediately after the last one The amount of foam was read from the tilting movement. Then shaking cylinders were left stand still and after 60 seconds the amount of foam was read again. 50 ml each of the readings were for the given solution deducted.

    Der in der Tabelle angegebene zweite Wert gibt den Schaumzerfall an, wobei Werte oberhalb 70/70 ml Probleme mit zu starkem Schaum anzeigen, was in der Praxis dazu führt, daß sich die Scheuersaugmaschine aufgrund des Schaumpolsters frühzeitig abstellt und die Kapazität des Gerätes nicht voll genutzt werden kann.The second value given in the table indicates the foam breakdown, where values above 70/70 ml show problems with too much foam, what in practice causes the scrubber drier early due to the foam pad turns off and the capacity of the device can not be fully used.

    Prüfung des DispergiervermögensTesting the dispersibility

    Das Dispergiervermögen wurde mit einem standardisierten Testschmutz nach der Schüttelmethode bestimmt.The dispersibility was measured using a standardized test dirt Shake method determined.
