Definitions
- the present invention relates to a detergent molding with a coating, in particular for the sanitary sector, and the method of its preparation.
- in-tank products cleaning agents that are positioned in the water box of the toilet and give some of the active ingredients to the water in the cistern, so that the rinse water is enriched in each flushing process by the detergent.
- in-tank products which also enrich the rinse water from the water tank, but which are not positioned in the water in the container, but in the piping between the actual water receiver and the outlet from the water box.
- the cleaning agent is also washed around like a Rimblock only during rinsing from the flow of water and is otherwise dry.
- the agent is, however, like a conventional "in-tank product" on / in the water tank, but not in the water.
- Water boxes for toilets which provide a "dry” storage of cleaning agents and a rinse the agent with rinse water only during flushing, are known for example from the company Ifö.
- the molded in the form of a long cylinder detergent are placed in special tubular containers in which they are then washed by the rinse water stream.
- the known detergent tablets are generally packed in water-soluble films placed on the market.
- the detergent tablets are filled into the cups or other containers in the form wrapped in the water-soluble films.
- the foliation avoids that residues of detergent stick to the hands of the consumer and the hands of the consumer are not stained blue in blue flushes.
- the film prevents "crumbling" of the agent and contributes to its mechanical stability.
- a further disadvantage of the known film, for example of PVA, is that it is sensitive to moisture in the production and storage, and at high humidity, the film can be processed poorly. Furthermore, the films lead to residues in the rinsing process, since in the moisture from the film partially forms a slimy mass.
- the water-soluble films are thermally sealed. Since the films easily decompose or chemically change under the action of heat, the dissolution behavior of the film is impaired.
- the U.S. Patent 3,856,932 teaches to disinfect swimming pools employing chill-spreading tablets embedded in a water-impermeable and water-insoluble material, at least one remaining area of the tablet being uncoated.
- a tablet containing calcium hypochlorite which can be used to clean the toilet bowl.
- This tablet is made by compression of a dry mixture of calcium hypochlorite with a water insoluble finely divided resin. If desired, this tablet may be further surrounded by a preformed shell of an inert polymer. The shell is made in such a way that it has an opening into which the tablet can then be inserted.
- the object of the present invention is to provide a surfactant comprising detergent tablets with a coating which allows good handling of the agent even in the high-color Blau Techern, impurities and color stains on the hands prevents abrasion, and an introduction of the detergent tablet even with more complex shapes in a corresponding complementarily shaped receptacle allows.
- the detergent tablet is coated with a liquid coating material comprising non-water-soluble resins as film formers and low-polarity to nonpolar organic solvents and the purging of the uncoated detergent tablet is at least 80 rinses and the rinse rate of the coated detergent tablet at least after curing which is 1.05 times the purging number of the uncoated detergent tablet.
- the purging number of the coated detergent tablet is thus at least 84, wherein the purging number across the coating the uncoated detergent tablet is increased at least to 1.05 times.
- the coating material does not dissolve the water-soluble constituents, in particular the dye, from the detergent tablet. Soiling of the hands is thus prevented.
- the paint film formed directly on the surface of the detergent molding after curing forms a dry, consistently hard, non-sticky, smooth surface.
- the coating is also water-insoluble. This leads to an extension of the service life of the coated detergent tablets compared to the uncoated detergent tablets, which in the case of local bar-shaped toilet cleaners, which should consume only gradually when rinsing with water, in contrast to the disposable tablets for the rinsing or Washing machine represents an additional advantage.
- non-water-soluble resins are understood as meaning resins which, after application and drying, can no longer be removed by rinsing with water at room temperature. After complete drying, these water-insoluble resins form a largely closed surface.
- Water-soluble resins in the context of the present invention are synthetic polymers whose solubility in water at 20 ° C. is less than 0.5% by weight, preferably less than 0.1% by weight and more preferably less than 0.05% by weight on the cured resin (as a pure substance).
- the drying of the coatings can be carried out independently (evaporation of the solvent and associated film formation by, for example, polycondensation reaction, polyaddition, etc.). Drying may also be by thermal processes (e.g., thermally induced polymerization or by exposure to UV light (resists)).
- the dissolution of the coated detergent molding takes place in that water penetrates through the water-insoluble paint layer through micropores and swelling takes place on the water-soluble cleaning agent molding.
- the swelling leads to an increase in volume, formation of new pores and hairline cracks and thus to successive blasting off of the lacquer layer.
- the lacquer layer itself does not dissolve in this process, but rather is blasted off in the form of small particles.
- the purging number of the coated detergent tablet may also be at least 1.10-fold, preferably at least 1.15-fold and more preferably at least 1.20-fold the purging number of the uncoated detergent tablet.
- Preferably used as resins are higher molecular weight physically drying film formers such as cellulose nitrate, cellulose acetate butyrate, thermoplastic acrylates or PVC copolymers - the aforementioned resins in each case also in modified form (for example with phthalic acid esters). These resins cure by release of the solvents without undergoing a chemical change during film formation (physical cure).
- relatively low molecular masses 20,000 to 100,000 g / mol
- low viscosities of the binder systems (flowable) and low glass transition temperatures which lead to drying of the resins to high molecular weight systems with high glass transition temperatures. These viscosities are no longer measurable.
- Typical examples of such paints are veraerosolte paints for end users, which can be obtained from hardware stores.
- fast-curing resins such as polyurethane or epoxy resin paints
- film formers also in modified form
- fast-curing resins such as polyurethane or epoxy resin paints
- the latter are usually used only in the form of two components because of their high chemical reactivity.
- non-water-soluble polyester resins and in particular alkyd resins, especially long- or medium-oil alkyd resins.
- alkyd resins especially long- or medium-oil alkyd resins.
- modified alkyd resins e.g. styrene-modified, acrylated, etc.
- the non-water-soluble resins from the group of acrylates are preferably acrylic esters, for example alkyl methacrylates such as methyl, ethyl, propyl or butyl methacrylate.
- Acrylate-based binders generally give off particularly water-resistant and, in the case of automotive finishes, also weather-resistant topcoats. Such paints can therefore be found u.a. in the accessory trade in the form of aerosol cans for the end user for the repair of paint damages on the motor vehicle.
- Chemically reactive systems contain e.g. additionally melamine resins or isocyanate curing crosslinkers (2-component paints).
- the coating of the detergent tablets takes place from non-aqueous solvents.
- the solvents are poorly polar or nonpolar organic solvents and preferably aprotic.
- the dielectric constant of the solvent (s) should be below 30, preferably below 20 and more preferably below 10.

Abstract
Description
Die vorliegende Erfindung betrifft einen Reinigungsmittelformkörper mit einer Beschichtung, insbesondere für den Sanitärbereich, und das Verfahren seiner Herstellung.The present invention relates to a detergent molding with a coating, in particular for the sanitary sector, and the method of its preparation.
Zur Reinigung von Toiletten werden einerseits Reinigungsmittelformkörper als Rimblocks, die am Toilettenrand in einem Körbchen befestigt werden und sich beim Überspülen mit Wasser nach und nach auflösen, eingesetzt.For cleaning toilets on the one hand detergent tablets are used as Rimblocks, which are attached to the toilet rim in a basket and gradually dissolve when rinsing with water used.
Andererseits sind sogenannte In-Tank-Produkte bekannt, Reinigungsmittel, die im Wasserkasten der Toilette positioniert werden und einen Teil der Wirkstoffe an das in dem Spülkasten befindliche Wasser abgeben, so dass das Spülwasser bei jedem Spülvorgang durch das Reinigungsmittel angereichert ist.On the other hand, so-called in-tank products are known, cleaning agents that are positioned in the water box of the toilet and give some of the active ingredients to the water in the cistern, so that the rinse water is enriched in each flushing process by the detergent.
Um dem Verbraucher optisch zu signalisieren, dass das Spülwasser aus dem Wasserkasten Reinigungsmittel enthält, sind diese In-Tank-Reinigungsmittel häufig angefärbt, insbesondere mit blauer Farbe, weshalb sie auch als "Blauspüler" bezeichnet werden.To visually signal to the consumer that the rinse water from the water box contains detergent, these in-tank detergents are often stained, especially with blue color, which is why they are also referred to as "blue rinse".
Weiterhin gibt es In-Tank-Produkte, durch die das Spülwasser aus dem Wassertank ebenfalls angereichert wird, die jedoch nicht in dem Wasser in dem Behälter positioniert sind, sondern in dem Leitungssystem zwischen dem eigentlichen Wasseraufnahmebehälter und dem Auslass aus dem Wasserkasten. Auf diese Weise wird das Reinigungsmittel ebenfalls wie bei einem Rimblock nur während des Spülens vom Wasserstrom umspült und ist ansonsten trocken. Das Mittel befindet sich jedoch wie bei einem herkömmlichen "In-Tank-Produkt" am/im Wasserkasten, jedoch nicht im Wasser.Further, there are in-tank products which also enrich the rinse water from the water tank, but which are not positioned in the water in the container, but in the piping between the actual water receiver and the outlet from the water box. In this way, the cleaning agent is also washed around like a Rimblock only during rinsing from the flow of water and is otherwise dry. The agent is, however, like a conventional "in-tank product" on / in the water tank, but not in the water.
Wasserkästen für Toiletten, die eine "trockene" Lagerung der Reinigungsmittel und ein Überspülen des Mittels mit Spülwasser nur beim Spülvorgang vorsehen, sind beispielsweise von der Firma Ifö bekannt. Bei diesen Wasserkästen werden die in Form eines langen Zylinders geformten Reinigungsmittel in spezielle rohrförmige Behältnisse eingefüllt, in denen sie dann vom Spülwasserstrom umspült werden.Water boxes for toilets, which provide a "dry" storage of cleaning agents and a rinse the agent with rinse water only during flushing, are known for example from the company Ifö. In these water tanks, the molded in the form of a long cylinder detergent are placed in special tubular containers in which they are then washed by the rinse water stream.
Die bekannten Reinigungsmittelformkörper werden im Allgemeinen eingepackt in wasserlöslichen Folien in Verkehr gebracht. Die Reinigungsmittelformkörper werden in der in die wasserlöslichen Folien eingewickelten Form in die Körbchen oder sonstigen Behältnisse eingefüllt. Durch die Folierung wird vermieden, dass Reinigungsmittelreste an den Händen des Verbrauchers haften und die Hände des Verbrauchers bei Blauspülern nicht blau angefärbt werden.The known detergent tablets are generally packed in water-soluble films placed on the market. The detergent tablets are filled into the cups or other containers in the form wrapped in the water-soluble films. The foliation avoids that residues of detergent stick to the hands of the consumer and the hands of the consumer are not stained blue in blue flushes.
Weiterhin verhindert die Folie ein "Zerbröseln" des Mittels und trägt zu dessen mechanischer Stabilität bei.Furthermore, the film prevents "crumbling" of the agent and contributes to its mechanical stability.
Durch die Umhüllung des Reinigungsmittelformkörpers mit der wasserlöslichen Folie treten jedoch Schwierigkeiten beim Einschieben der Reinigungsmittelformkörper in die jeweiligen Behältnisse wie WC-Körbchen und insbesondere die langen rohrförmigen Reinigungsmittelaufnahmebehälter, die im Wassertank außerhalb des Spülstroms gelagerten sind, auf, da die Folien auf- oder abgerissen werden oder verhaken, wodurch eine weiteres Einschieben des Mittels in den Aufnahmebehälter verhindert wird.By wrapping the detergent tablet with the water-soluble film, however, difficulties arise when inserting the detergent tablets in the respective containers such as toilet bowls and in particular, the long tubular detergent accommodating containers stored in the water tank outside the purge stream because the sheets are torn or torn or snagged thereby preventing further insertion of the agent into the receptacle.
Weiterhin ist bei figürlichen Reinigungsmittelformkörpern, die im Allgemeinen nicht extrudiert, sondern spritzgegossen oder gepresst werden, nachteilig, dass eine die figürliche Form nachbildende Verpackung, beispielsweise in Form von Tierfiguren, in ein entsprechend der Tierfigur komplementär geformtes Aufnahmekörbchen (Schlüssel-Schloss-Prinzip) infolge der die Figur nicht nachbildenden Folie nicht möglich ist.Furthermore, in figurative detergent tablets, which are generally not extruded, but injection molded or pressed, disadvantageous that a figurative shape modeled packaging, for example in the form of animal figures, in a corresponding to the animal figure complementarily shaped receiving basket (key-lock principle) due the figure does not imitate the figure is not possible.
Ein weiterer Nachteil der bekannten Folie beispielsweise aus PVA ist, dass diese bei der Herstellung und Lagerung feuchtigkeitsempfindlich ist, und bei hoher Luftfeuchtigkeit lässt sich die Folie schlecht verarbeiten. Weiterhin führen die Folien zu Rückständen beim Spülprozess, da sich in der Feuchtigkeit aus der Folie teilweise eine schleimige Masse bildet.A further disadvantage of the known film, for example of PVA, is that it is sensitive to moisture in the production and storage, and at high humidity, the film can be processed poorly. Furthermore, the films lead to residues in the rinsing process, since in the moisture from the film partially forms a slimy mass.
Die wasserlöslichen Folien werden thermisch versiegelt. Da sich die Folien unter Hitzeeinwirkung leicht zersetzen oder chemisch verändern kommt es zu Beeinträchtigungen des Auflöseverhaltens der Folie.The water-soluble films are thermally sealed. Since the films easily decompose or chemically change under the action of heat, the dissolution behavior of the film is impaired.
Aus dem Stand der Technik sind weiterhin verschiedene Reinigungsmittelformkörper für Spül- und Waschmaschinen mit wasserlöslichen Beschichtungen bekannt, die den Mitteln eine höhere Oberflächenhärte verleihen. Diese Beschichtungen bestehen beispielsweise aus Polyvinylalkohol, Polyvinylpyrrolidon oder Polyethylenglykol und werden im Allgemeinen aus einer wässrigen Lösung auf den Reinigungsmittelformkörper aufgebracht. Diese Beschichtungen sind leicht wasserlöslich.Various detergent tablets for rinsing and washing machines with water-soluble coatings are known from the prior art, which give the compositions a higher surface hardness. These coatings consist for example of polyvinyl alcohol, polyvinylpyrrolidone or polyethylene glycol and are generally applied to the detergent tablet from an aqueous solution. These coatings are easily soluble in water.
Der Auftrag einer solchen bekannten Beschichtung auf die Blauspüler führt jedoch aufgrund der in den Blauspülern vorhandenen stark färbenden blauen Farbstoffe dazu, dass sich beim Auftragen der Beschichtung der Farbstoff aus dem Blauspüler herausgelöst, in die Beschichtung und auf die Oberfläche der Beschichtung wandert, so dass ein solcher beschichteter Blauspüler ebenfalls färbt, die Hände verunreinigt und nicht eingesetzt werden kann.However, the application of such a known coating on the Blauspüler leads due to the present in the Blauspülern strong coloring blue dyes that when applying the coating, the dye dissolved out of the Blauspüler, migrates into the coating and on the surface of the coating, so that a such coated Blauspüler also colors, the hands contaminated and can not be used.
Das
Aus dem
Die Aufgabe der vorliegenden Erfindung besteht darin, einen Tenside umfassenden Reinigungsmittelformkörper mit einer Beschichtung bereitzustellen, der eine gute Handhabung des Mittels selbst bei den stark färbenden Blauspülern ermöglicht, Verunreinigungen und Farbflecken an den Händen verhindert, abriebfest ist und eine Einführung des Reinigungsmittelformkörpers selbst bei komplexeren Formen in einem entsprechenden komplementär geformten Aufnahmebehältnis ermöglicht.The object of the present invention is to provide a surfactant comprising detergent tablets with a coating which allows good handling of the agent even in the high-color Blauspülern, impurities and color stains on the hands prevents abrasion, and an introduction of the detergent tablet even with more complex shapes in a corresponding complementarily shaped receptacle allows.
Diese Aufgabe wird dadurch gelöst, dass der Reinigungsmittelformkörper mit einem flüssigen Beschichtungsmaterial beschichtet wird, das nicht wasserlösliche Harze als Filmbildner und wenig polare bis unpolare organische Lösemittel umfasst und die Spülzahl des unbeschichteten Reinigungsmittelformkörpers wenigstens 80 Spülungen beträgt und die Spülzahl des beschichteten Reinigungsmittelformkörpers nach dem Aushärten wenigstens das 1,05-fache der Spülzahl des unbeschichteten Reinigungsmittelformkörpers beträgt.This object is achieved in that the detergent tablet is coated with a liquid coating material comprising non-water-soluble resins as film formers and low-polarity to nonpolar organic solvents and the purging of the uncoated detergent tablet is at least 80 rinses and the rinse rate of the coated detergent tablet at least after curing which is 1.05 times the purging number of the uncoated detergent tablet.
Die Spülzahl des beschichteten Reinigungsmittelformkörpers beträgt somit wenigstens 84, wobei die Spülzahl durch die Beschichtung gegenüber dem unbeschichteten Reinigungsmittelformkörper wenigstens auf das 1,05-fache erhöht ist.The purging number of the coated detergent tablet is thus at least 84, wherein the purging number across the coating the uncoated detergent tablet is increased at least to 1.05 times.
Durch die Beschichtung des Reinigungsmittelformkörpers mit dem in dem unpolaren Lösemittel gelösten Filmbildner löst das Beschichtungsmaterial die wasserlöslichen Bestandteile, insbesondere den Farbstoff, aus dem Reinigungsmittelformkörper nicht an. Eine Verschmutzung der Hände wird somit verhindert.As a result of the coating of the detergent tablet with the film former dissolved in the non-polar solvent, the coating material does not dissolve the water-soluble constituents, in particular the dye, from the detergent tablet. Soiling of the hands is thus prevented.
Der direkt auf der Oberfläche des Reinigungsmittelformkörpers nach der Aushärtung gebildete Lackfilm bildet eine trockene, durchgängig harte, nicht klebrige, glatte Oberfläche.The paint film formed directly on the surface of the detergent molding after curing forms a dry, consistently hard, non-sticky, smooth surface.
Die Beschichtung ist zudem wasserunlöslich. Dies führt zu einer Verlängerung der Standzeiten der beschichteten Reinigungsmittelformkörper im Vergleich zu den unbeschichteten Reinigungsmittelformkörpern, was im Falle der hiesigen stückförmigen Toilettenreinigungsmittel, die sich beim Überspülen mit Wasser erst nach und nach verbrauchen sollen, im Gegensatz zu den Einmal-Tabs für die Spül- oder Waschmaschine einen zusätzlichen Vorteil darstellt.The coating is also water-insoluble. This leads to an extension of the service life of the coated detergent tablets compared to the uncoated detergent tablets, which in the case of local bar-shaped toilet cleaners, which should consume only gradually when rinsing with water, in contrast to the disposable tablets for the rinsing or Washing machine represents an additional advantage.
Unter nicht wasserlöslichen Harzen werden im Rahmen der Erfindung Harze verstanden, die sich nach Applikation und Abtrocknen nicht mehr durch Bespülen mit Wasser bei Raumtemperatur entfernen lassen. Nach dem vollständigen Abtrocknen bilden diese wasserunlöslichen Harze eine weitgehend geschlossene Fläche.In the context of the invention, non-water-soluble resins are understood as meaning resins which, after application and drying, can no longer be removed by rinsing with water at room temperature. After complete drying, these water-insoluble resins form a largely closed surface.
Wasserlösliche Harze sind im Rahmen der vorliegenden Erfindung synthetische Polymere, deren Löslichkeit in Wasser bei 20 °C kleiner als 0,5 Gew.%, vorzugsweise kleiner als 0,1 Gew.% und besonders bevorzugt kleiner als 0,05 Gew.% in Bezug auf das ausgehärtete Harz (als Reinstoff) ist.Water-soluble resins in the context of the present invention are synthetic polymers whose solubility in water at 20 ° C. is less than 0.5% by weight, preferably less than 0.1% by weight and more preferably less than 0.05% by weight on the cured resin (as a pure substance).
Die erfindungsgemäßen Harze sind aus monomeren Strukturen oder substituierten Strukturen des nachfolgenden Typus aufgebaut (die entsprechenden Harze sind in Klammern angefügt):
- a) Acrylnitril, Butadien, Styrol (ABS-Harze)
- b) Formaldehyd mit arylischen/alkylischen Aminofunktionen (Aminoplaste)
- c) Formaldehyd und Milcheiweiße (Kunsthorn)

Ebenfalls einsetzbar sind Kombinationen dieser Harze untereinander oder in Form von Copolymeren oder Pfropf(co)polymeren. Die sinnvolle Applikation setzt ggf. die Auswahl eines geeigneten Lösemittels für das verwendete Harz voraus. Bei zwei- oder mehrkomponentigen Systemen ist auf Applikationshilfen, die dem Fachmann bekannt sind, auszuweichen (z.B. Sprühgeräte mit separierten Kammern für die unterschiedlichen Komponenten).Also usable are combinations of these resins with each other or in the form of copolymers or graft (co) polymers. The useful application may require the selection of a suitable solvent for the resin used. In two- or multi-component systems, application aids which are known to the person skilled in the art are to be avoided (eg sprayers with separate chambers for the different components).
Die Trocknung der Beschichtungen kann selbstständig erfolgen (Verdunsten des Lösemittels und damit verbundene Filmbildung durch z.B. Polykondensationsreaktion, Polyaddition etc.). Die Trocknung kann auch durch thermische Verfahren (z.B. thermisch induzierte Polymerisation oder durch Bestrahlung mit UV Licht (Fotolacke) erfolgen).The drying of the coatings can be carried out independently (evaporation of the solvent and associated film formation by, for example, polycondensation reaction, polyaddition, etc.). Drying may also be by thermal processes (e.g., thermally induced polymerization or by exposure to UV light (resists)).
Die Auflösung des beschichteten Reinigungsmittelformkörpers findet dadurch statt, dass durch Mikroporen Wasser durch die wasserunlösliche Lackschicht eindringt und am wasserlöslichen Reinigungsmittelformkörper eine Quellung stattfindet. Die Quellung führt zu einer Volumenvergrößerung, Bildung von neuen Poren und Haarrissen und dadurch zum sukzessiven Absprengen der Lackschicht. Die Lackschicht selbst löst sich bei diesem Vorgang nicht auf, sondern wird vielmehr in Form von kleinen Partikeln abgesprengt.The dissolution of the coated detergent molding takes place in that water penetrates through the water-insoluble paint layer through micropores and swelling takes place on the water-soluble cleaning agent molding. The swelling leads to an increase in volume, formation of new pores and hairline cracks and thus to successive blasting off of the lacquer layer. The lacquer layer itself does not dissolve in this process, but rather is blasted off in the form of small particles.
In Abhängigkeit von der Beschichtung kann die Spülzahl des beschichteten Reinigungsmittelformkörpers auch wenigstens das 1,10-fache, vorzugsweise wenigstens das 1,15-fache und besonders bevorzugt wenigstens das 1,20-fache der Spülzahl des unbeschichteten Reinigungsmittelformkörpers betragen.Depending on the coating, the purging number of the coated detergent tablet may also be at least 1.10-fold, preferably at least 1.15-fold and more preferably at least 1.20-fold the purging number of the uncoated detergent tablet.
Vorzugsweise werden als Harze höher molekulare physikalisch trocknende Filmbildner wie Cellulosenitrat, Celluloseacetatobutyrat, thermoplastische Acrylate oder PVC-Mischpolymerisate - vorgenannte Harze jeweils auch in modifizierter Form (zum Beispiel mit Phthalsäureestern) - eingesetzt. Diese Harze härten durch Abgabe der Lösemittel aus, ohne bei der Filmbildung eine chemische Veränderung zu durchlaufen (physikalische Härtung). Typisch sind dabei relativ niedere molekulare Massen (20.000 bis 100.000 g/mol) mit geringen Viskositäten der Bindersysteme (fließfähig) sowie niedere Glasübergangstemperaturen, die nach Abtrocknung der Harze zu hochmolekularen Systemen mit hohen Glasübergangstemperaturen führen. Diese Viskositäten sind nicht mehr messbar. Typische Beispiele solcher Lacke sind veraerosolte Lacke für Endverbraucher, die man über Baumärkte beziehen kann.Preferably used as resins are higher molecular weight physically drying film formers such as cellulose nitrate, cellulose acetate butyrate, thermoplastic acrylates or PVC copolymers - the aforementioned resins in each case also in modified form (for example with phthalic acid esters). These resins cure by release of the solvents without undergoing a chemical change during film formation (physical cure). Typically, relatively low molecular masses (20,000 to 100,000 g / mol) with low viscosities of the binder systems (flowable) and low glass transition temperatures, which lead to drying of the resins to high molecular weight systems with high glass transition temperatures. These viscosities are no longer measurable. Typical examples of such paints are veraerosolte paints for end users, which can be obtained from hardware stores.
Ebenfalls können schnell härtende Harze wie Polyurethan- oder Epoxidharzlacke - auch in modifizierter Form - als Filmbildner eingesetzt werden. Letztere kommen wegen ihrer hohen chemischen Reaktivität in der Regel nur in Form von zwei Komponenten zum Einsatz.It is also possible to use fast-curing resins, such as polyurethane or epoxy resin paints, also in modified form, as film formers. The latter are usually used only in the form of two components because of their high chemical reactivity.
Auch ist es möglich, nicht wasserlösliche Polyesterharze und insbesondere Alkydharze einzusetzen, insbesondere lang- oder mittelölige Alkydharze. Der Einsatz von modifizierten Alkydharzen, z.B. styrolmodifiziert, acryliert etc., ist ebenfalls möglich.It is also possible to use non-water-soluble polyester resins and in particular alkyd resins, especially long- or medium-oil alkyd resins. The use of modified alkyd resins, e.g. styrene-modified, acrylated, etc., is also possible.
Die nicht wasserlöslichen Harze aus der Gruppe der Acrylate sind vorzugsweise Acrylsäureester, beispielsweise Alkylmethacrylate wie Methyl-, Ethyl-, Propyl- oder Butylmethacrylat.The non-water-soluble resins from the group of acrylates are preferably acrylic esters, for example alkyl methacrylates such as methyl, ethyl, propyl or butyl methacrylate.
Acrylatbasierte Bindemittel geben in der Regel besonders wasserfeste und im Bereich der Autolacke auch wetterbeständige Decklacke ab. Solche Lacke findet man deshalb u.a. im Zubehörhandel in der Form von Aerosol-Dosen für den Endverbraucher zur Reparatur von Lackschäden am Kfz.Acrylate-based binders generally give off particularly water-resistant and, in the case of automotive finishes, also weather-resistant topcoats. Such paints can therefore be found u.a. in the accessory trade in the form of aerosol cans for the end user for the repair of paint damages on the motor vehicle.
Chemisch reaktive Systeme enthalten z.B. zusätzlich Melaminharze oder mit Isocyanathärter ausgestattete Vernetzer (2-K-Lacke).Chemically reactive systems contain e.g. additionally melamine resins or isocyanate curing crosslinkers (2-component paints).
Erfindungsgemäß erfolgt die Beschichtung der Reinigungsmittelformkörper aus nicht wässrigen Lösemitteln. Um ein Anlösen der wasserlöslichen Komponenten des Reinigungsmittelformkörpers zu verhindern sind die Lösemittel wenig polare oder unpolare organische Lösemittel und vorzugsweise aprotisch. Die Dielektrizitätskonstante des/der Lösemittel sollte unter 30, vorzugsweise unter 20 und besonders bevorzugt unter 10, liegen.According to the invention, the coating of the detergent tablets takes place from non-aqueous solvents. In order to prevent the water-soluble components of the detergent tablet from being dissolved, the solvents are poorly polar or nonpolar organic solvents and preferably aprotic. The dielectric constant of the solvent (s) should be below 30, preferably below 20 and more preferably below 10.
Beispiele von geeigneten Lösemitteln sind aromatische Kohlenwasserstoffe wie Xylol oder Solventnaphtha, aliphatische Kohlenwasserstoffe wie Testbenzin oder Kristallöl, Ester wie Ethylacetat oder Butylacetat, oder höhere Alkohole wie Propanol oder Butanol, Ether wie Butylglykol, Etherester als Ethyl- oder Butylglykolacetat sowie diverse Ketone.Examples of suitable solvents are aromatic hydrocarbons such as xylene or solvent naphtha, aliphatic hydrocarbons such as white spirit or crystal oil, esters such as ethyl acetate or butyl acetate, or higher alcohols such as propanol or butanol, ethers such as butyl glycol, ether esters as ethyl or butyl glycol acetate and various ketones.
Selbstverständlich können im Rahmen der vorliegenden Erfindung auch Lösemittelgemische eingesetzt werden.Of course, solvent mixtures can also be used in the context of the present invention.
Die Trockenzeiten (die Zeit, bis der beschichtete Körper beim Anfassen nicht mehr klebrig ist) sollte bei Raumtemperatur bei einem Sprühgang mit einer aufgetragenen Schichtdicke von 10 bis 30 µm zwischen 30 s und zwei Stunden, insbesondere zwischen 5 min. und 15 min., liegen.The drying times (the time until the coated body is no longer tacky when touched) should at room temperature in a spray with an applied layer thickness of 10 to 30 microns between 30 s and two hours, in particular between 5 min. and 15 min., lie.
Der Anteil an Lösemittel sollte in der Beschichtungslösung/suspension zwischen 20 Gew.% und 80 Gew.%, vorzugsweise zwischen 30 Gew.% und 60 Gew.%, betragen.The proportion of solvent in the coating solution / suspension should be between 20% by weight and 80% by weight, preferably between 30% by weight and 60% by weight.
Der Anteil an wasserunlöslichen Harzen sollte in der Beschichtungslösung zwischen 10 Gew.% und 80 Gew.% und vorzugsweise zwischen 15 Gew.%. und 50 Gew.% betragen.The proportion of water-insoluble resins in the coating solution should be between 10% by weight and 80% by weight and preferably between 15% by weight. and 50% by weight.
Die Beschichtungslösung besteht zu wenigstens 80 Gew.%, vorzugsweise zu wenigstens 90 Gew.% und besonders bevorzugt zu wenigstens 95 Gew.% aus Harzen und Lösemitteln.The coating solution consists of at least 80% by weight, preferably at least 90% by weight and more preferably at least 95% by weight, of resins and solvents.
Selbstverständlich kann die Beschichtungslösung als weitere Bestandteile Additive, Pigmente, Füllstoffe oder weitere Hilfsmittel wie z.B. Verlaufsmittel, Antioxidantien oder Entschäumer enthalten.Of course, the coating solution may contain as further constituents additives, pigments, fillers or other auxiliaries, such as e.g. Contains leveling agents, antioxidants or defoamers.
Die Dicke der auf dem Reinigungsmittelformkörper aufgebrachten Beschichtung kann in Abhängigkeit von der eingesetzten Beschichtungslösung, deren Konzentration und den gewünschten Spülzahlen des beschichteten Reinigungsmittelformkörpers variieren. Vorzugsweise sollte sie zwischen 5 µm und 50 µm, insbesondere zwischen 10 µm und 30 µm, liegen.The thickness of the coating applied to the detergent tablet may vary depending on the coating solution used, its concentration and the desired flushing numbers of the coated detergent tablet. Preferably, it should be between 5 .mu.m and 50 .mu.m, in particular between 10 .mu.m and 30 .mu.m.
Die erfindungsgemäße Beschichtung kann durch Tauchen, Spritzen, Sprühen, Rollen, Walz-, Flut- und Gießverfahren oder andere bekannte Applikationsverfahren auf die Außenflächen des Reinigungsmittelformkörpers aufgebracht werden.The coating according to the invention can be applied to the outer surfaces of the detergent tablet by dipping, spraying, spraying, rolling, rolling, flooding and casting or other known application methods.
In der Regel wird die gesamte Oberfläche des Reinigungsmittelformkörpers vollständig mit dem Beschichtungsmaterial beschichtet. Der Lackfilm haftet dabei direkt auf der Oberfläche und bildet eine die Reinigungsmittelformkörperoberfläche vollständig bedeckende Schicht.As a rule, the entire surface of the detergent tablet is completely coated with the coating material. The paint film adheres directly to the surface and forms a detergent mold surface completely covering layer.
Die vollständige Beschichtung wird insbesondere verwirklicht, wenn das zu beschichtende Material tauchlackiert wird oder eine Sprühbeschichtung durchläuft.The complete coating is particularly realized when the material to be coated is dip-coated or passes through a spray coating.
Darüber hinaus ist es möglich, im Bereich der Aufhängung keine Beschichtung vorzunehmen oder einzelne Bereiche des Reinigungsmittelformkörpers unbeschichtet zu lassen, um damit beim verwendungsgemäßen Gebrauch eine direkte Aktivierung zu gewährleisten.In addition, it is possible to make no coating in the area of the suspension or to leave individual areas of the detergent tablet uncoated in order to ensure direct activation during use according to the purpose.
Neben den zuvor beschriebenen Vorzügen des erfindungsgemäß beschichteten Reinigungsmittelformkörpers wird durch die Beschichtung auch das optische Erscheinungsbild des Mittels verbessert.In addition to the advantages of the inventively coated detergent tablet described above, the coating also improves the visual appearance of the agent.
Auch ist das Einbringen von komplexer geformten (dreidimensionalen), beschichteten Reinigungsmittelformkörpern in die entsprechen geformten Aufnahmebehälter problemlos möglich.Also, the introduction of complex shaped (three-dimensional) coated detergent tablets in the corresponding shaped receptacle is easily possible.
Der Reinigungsmittelformkörper umfasst Tenside, um die gewünschte Reinigungswirkung zu erzielen, insbesondere zwischen 5 Gew.% und 75 Gew.% und vorzugsweise zwischen 10 Gew.% und 60 Gew.% Tenside. Diese Tenside sollten zur Erzielung der gewünschten Reinigung gut netzende Tenside, somit vorzugsweise anionische oder nichtionische Tenside, sein. Prinzipiell sind alle bekannten anionischen Tenside geeignet. Vorzugsweise werden als anionische Tenside Alkylbenzolsulfonate, Alkylsulfate, Fettalkoholsulfate und Fettalkoholethersulfate eingesetzt. Vorzugsweise umfasst die Alkylgruppe oder der Fettsäurebestandteil zwischen 8 und 18 Kohlenstoffatome. Als Alkylbenzolsulfonat kann beispielsweise Natrium-alkyl-(C10-C13)-benzolsulfonat eingesetzt werden.The detergent tablet comprises surfactants to achieve the desired cleaning effect, in particular between 5% by weight and 75% by weight and preferably between 10% by weight and 60% by weight of surfactants. These surfactants should be well wetting surfactants, thus preferably anionic or nonionic surfactants, to achieve the desired cleaning. In principle, all known anionic surfactants are suitable. The anionic surfactants used are preferably alkylbenzenesulfonates, alkyl sulfates, fatty alcohol sulfates and fatty alcohol ether sulfates. Preferably, the alkyl group or fatty acid component comprises between 8 and 18 carbon atoms. As the alkylbenzenesulfonate, for example, sodium alkyl (C10-C13) benzene sulfonate can be used.
Weiterhin kann der Reinigungsmittelformkörper als Füllstoffe Salze zur Regulierung der Konsistenz und des Abspülverhaltens enthalten. Im Allgemeinen handelt es sich bei diesen Salzen um anorganische Salze, die vorzugsweise aus der Gruppe der Alkali- und Erdalkalisalze der Schwefelsäuren, Phosphorsäuren, Stickstoffsäuren, Kohlensäure, Halogensäuren wie HCl oder deren Mischungen ausgewählt werden. Der Anteil an diesen Salzen in der zweiten Phase kann bis zu 80 Gew.% betragen, vorzugsweise etwa 20 bis 50 Gew.%. Besonders bevorzugt ist, als Salze Natriumchlorid oder Natriumsulfat oder deren Mischung einzusetzen.Furthermore, the detergent tablets may contain as fillers salts for regulating the consistency and the rinsing behavior. In general, these salts are inorganic salts, which are preferably selected from the group of the alkali and alkaline earth salts of sulfuric acids, phosphoric acids, nitrogen acids, carbonic acid, halogen acids such as HCl or mixtures thereof. The proportion of these salts in the second phase may be up to 80% by weight, preferably about 20 to 50% by weight. It is particularly preferred to use as salts sodium chloride or sodium sulfate or a mixture thereof.
Weiterhin kann der Reinigungsmittelformkörper Extrusionshilfsmittel, Farbstoffe, Pigmente wie beispielsweise Titandioxid, amphotere Tenside (Schäumer) und Duftstoffe umfassen. Optional kann das Mittel auch Desinfektionsmittel, Konservierungsmittel, Bleichmittel, Aktivatoren, Enzyme, Komplexierungsmittel und Säuren umfassen.Furthermore, the detergent tablet may comprise extrusion aids, dyes, pigments such as titanium dioxide, amphoteric surfactants (foaming agents) and fragrances.
