Description

"Antislipmittel" "Anti-slip agent"
Die vorliegende Erfindung betrifft ein Antislipmittel auf Basis einer wäßrigen Dispersion sowie deren Verwendung für nichtsaugende Gegenstände.The present invention relates to an anti-slip agent based on an aqueous dispersion and the use thereof for non-absorbent articles.
Antislipmittel sollen ein Verrutschen, d.h. eine unbeabsichtigte gleitende Verschiebung zweier Gegenstände zueinander verhindern, jedoch ihre Trennung voneinander ohne weiteres ermöglichen. Das wird in der Regel dadurch erreicht, daß das Antislipmittel Bewe¬ gungen in Gleitrichtung großen Widerstand entgegensetzt, Bewegungen senkrecht dazu, jedoch keinen oder einen so geringen Widerstand, daß die Oberflächen der getrennten Gegenstände nicht beschädigt werden. Rohstoff-Basis für diese Antislipmittel sind in der Regel natürliche oder synthetische makromolekulare Stoffe, wie sie auch für Klebstoffe verwendet werden. Ähnlich wie bei den Klebstoffen können auch die Antislipmittel frei von verdunstenden Lösungs- oder Dispergiermitteln aus der Schmelze auf einen zu sichernden Gegen¬ stand aufgetragen werden (siehe z.B. DE-A-19 17 566). Dieses Ver¬ fahren erfordert spezielle Vorrichtungen zum Aufschmelzen und Applizieren des Antislipmittels. Üblicher ist es, die makromolekularen Stoffe in Form einer Lösung in organischen Lö¬ sungsmitteln oder in Form einer wäßrigen Dispersion aufzutragen.Antislip agents are said to slip, i.e. prevent an inadvertent sliding movement of two objects to one another, but enable their separation from one another without further notice This is generally achieved in that the anti-slip agent opposes large resistance to movements in the sliding direction, movements perpendicular to it, but no or so little resistance that the surfaces of the separated objects are not damaged. The raw material basis for these anti-slip agents are usually natural or synthetic macromolecular substances, as are also used for adhesives. Similar to the adhesives, the anti-slip agents can also be applied to an object to be secured free of evaporating solvents or dispersing agents from the melt (see e.g. DE-A-19 17 566). This process requires special devices for melting and applying the anti-slip agent. It is more common to apply the macromolecular substances in the form of a solution in organic solvents or in the form of an aqueous dispersion.
Bei der Anwendung der Antislipmittel für wasseraufsaugende Gegen¬ stände, wie z.B. Verpackungen aus Karton, Pappe oder Papier oder bei der Beschichtung von Teppichen basieren die Antislipmittel heute in der Regel auf wäßrigen Lösungen oder Dispersionen. So be¬ schreibt die DE-C-1943731 die Verwendung von wäßrigen Lösungen des Kolloids Xanthan-Gu als Haftmittel für Verpackungsmittel. Die DE-C-1262897 schlägt die Verwendung von wäßrigen Dispersionen von Polymerisaten olefinisch ungesättigter Verbindungen vor, insbeson¬ dere von Polyvinylacetaten und dessen Copolymeren. Gemäß der DE- C-20 31 881 können auch wäßrige Dispersionen von Paraffinen und/oder Polyalkylenen verwendet werden. In der DD 156612 wird ein Verfahren zur Rückenausrüstung von Teppichbodenmaterial be¬ schrieben, das dem Teppichboden eine feste transparente nichtkle- bende und rutschfeste Appretur verleiht. Dazu wird eine niedrig¬ viskose Mischung aus einem Copoly erisat-Latex des Butadiens mit Styrol und/oder Acrylnitril mit pulverförmigen Polyvinylchlorid mit einem Mischungsfeststoffanteil von 40 bis 55 % hergestellt, auf den Teppichrücken aufgetragen und anschließend getrocknet. Der Zusatz des Polyvinylchlorids zum Butadien-Copolymerisat verringert dessen sonst störende Klebrigkeit, ohne das gute Rutschfestigkeitsver¬ halten auf unterschiedlichen Fußbodenarten wie Holz, Steinholz und Kunststoff zu stören. Die Beschichtungsmischung zeigt sehr gute Adhäsionseigenschaften zu Natur- wie auch zu Synthesefasern.When using the anti-slip agents for water-absorbent objects, such as packaging made of cardboard, cardboard or paper or Today, when coating carpets, the anti-slip agents are usually based on aqueous solutions or dispersions. For example, DE-C-1943731 describes the use of aqueous solutions of the colloid xanthan gum as an adhesive for packaging. DE-C-1262897 proposes the use of aqueous dispersions of polymers of olefinically unsaturated compounds, in particular polyvinyl acetates and their copolymers. According to DE-C-20 31 881, aqueous dispersions of paraffins and / or polyalkylenes can also be used. DD 156612 describes a method for backing carpeting material which gives the carpeting a firm, transparent, non-adhesive and non-slip finish. For this purpose, a low-viscosity mixture of a copoly erisate latex of butadiene with styrene and / or acrylonitrile with powdery polyvinyl chloride with a mixture solids content of 40 to 55% is produced, applied to the back of the carpet and then dried. The addition of the polyvinyl chloride to the butadiene copolymer reduces its otherwise troublesome tack, without interfering with the good non-slip behavior on different types of flooring, such as wood, stone wood and plastic. The coating mixture shows very good adhesion properties to natural as well as synthetic fibers.
Für nichtwasseraufsaugende Gegenstände werden in der Regel Antislipmittel auf der Basis einer organischen Lösung von Polymeren oder Harzen verwendet. So schlägt die JP-A-59172569 Lösungen von Ethylen-Vinylacetat-Copolymeren und einem hydrierten Glycidylester des Kolophonium (Ester Gum H) in Toluol zur Verwendung in Aero¬ sol-Dosen vor. Andere herkömmliche Antislipmittel verwenden Chlorkohlenwasserstoffe wie Methylenchlorid als Lösungsmittel für synthetische Polymere wie Polybutadien. Aus arbeitshygienischen und ökologischen Gründen sollten derartige Lösungsmittel jedoch ver¬ mieden werden. Je nach konkretem Einsatzgebiet sind darüber hinaus noch weitere Anforderungen zu erfüllen: So sollte in den meisten Fällen der Antislipeffekt bei Einwirkung von Wasser nicht verringert werden, z.B. indem der Antislipfilm redispergiert. In vielen weiteren Fäl¬ len ist eine Verklebung der Gegenstände bei erhöhter Temperatur unerwünscht, wenn sie nach der Trennung der Gegenstände zu einer Zerstörung der Oberfläche führt. Das heißt, der Widerstand gegen Bewegungen senkrecht zu den Gegenstandsoberflächen sollte möglichst klein sein. Dagegen sollte der Antislipeffekt möglichst groß sein, d.h. der Widerstand gegen Bewegungen parallel zu den Oberflächen.Antislip agents based on an organic solution of polymers or resins are generally used for non-water-absorbent articles. JP-A-59172569 proposes solutions of ethylene-vinyl acetate copolymers and a hydrogenated glycidyl ester of rosin (ester gum H) in toluene for use in aerosol cans. Other conventional anti-slip agents use chlorinated hydrocarbons such as methylene chloride as solvents for synthetic polymers such as polybutadiene. Such solvents should, however, be avoided for occupational hygiene and ecological reasons. Depending on the specific area of application, additional requirements must also be met: in most cases, the anti-slip effect should not be reduced when exposed to water, for example by redispersing the anti-slip film. In many other cases, an adhesive bonding of the objects at an elevated temperature is undesirable if, after the separation of the objects, the surface is destroyed. This means that the resistance to movements perpendicular to the object surfaces should be as small as possible. In contrast, the anti-slip effect should be as large as possible, ie the resistance to movements parallel to the surfaces.
Aufgabe der vorliegenden Erfindung ist es, ein Antislipmittel zu schaffen, daß diese Nachteile nicht hat, also eine unproblematische Verarbeitung auch auf nichtwasseraufsaugenden Gegenständen ermög¬ licht sowie zu einem hohen temperatur- und wasserfesten Antislipeffekt führt.The object of the present invention is to provide an anti-slip agent which does not have these disadvantages, that is to say that it can be processed without problems even on non-water-absorbent objects and leads to a high temperature and water-resistant anti-slip effect.
Die erfindungsgemäße Lösung ist den Patentansprüchen zu entnehmen. Sie besteht im wesentlichen in der Auswahl des Polymerisats aus Styrol und einem Dien wie Isopren oder Butadien als Basis für das Antislipmittel. Das erfindungsgemäße Antislipmittel basiert also zweckmäßigerweise auf einer wäßrigen Dispersion von 25 bis 70, vorzugsweise 50 bis 55 Gew.% eines vorzugsweise carboxylgruppenhaltigen Polymerisates aus Styrol und Butadien im Gewichtsverhältnis von 20 : 80 bis 80 : 20, insbesondere von 35 : 65 bis 65 : 35 und von 0 bis 20, insbesondere 0,05 bis 10 und vorzugsweise 0,1 bis 2,0 Gew.% eines Viskositätsreglers sowie von 0 bis 5, vorzugsweise 0,1 bis 1,0 Gew.% eines Alterungsschutz¬ mittels, wobei sich die Gew.% auf die Zusammensetzung des fertigen Antislipmittels insgesamt beziehen, also einschließlich des rest¬ lichen Wassers.The solution according to the invention can be found in the patent claims. It consists essentially in the selection of the polymer from styrene and a diene such as isoprene or butadiene as the basis for the anti-slip agent. The antislip agent according to the invention is therefore expediently based on an aqueous dispersion of 25 to 70, preferably 50 to 55% by weight of a polymer of styrene and butadiene, preferably containing carboxyl groups, in a weight ratio of 20:80 to 80:20, in particular 35:65 to 65:35 and from 0 to 20, in particular 0.05 to 10 and preferably 0.1 to 2.0% by weight of a viscosity regulator and from 0 to 5, preferably 0.1 to 1.0% by weight of an anti-aging agent, where the% by weight relates to the composition of the finished antislip agent as a whole, ie including the remaining water.
Die Basis für die erfindungsgemäßen Antislipmittel stellen also Copolymerisate eines Diens wie Isopren oder Butadien mit Styrol dar, die noch zweckmäßigerweise etwa 0,5 bis 5, vorzugsweise 1 bis 3 Mol-% an Carboxylgruppen im Molekül enthalten. Derartige Mischpolymerisate können durch Polymerisation in wäßriger Disper¬ sion hergestellt werden, wobei als drittes Comonomeres eine ethylenisch ungesättigte Verbindung mit einer Carboxylseitengruppe oder deren Substituenten eingesetzt wird. Beispiele für solche carboxylgruppenhaltige Comonomere sind α,ß-ethylenisch ungesättigte Mono- und Dicarbonsäuren sowie deren Gemische und Salze. Konkrete Beispiele sind Acrylsäure, Methacrylsäure, Maleinsäure, Fu arsäure, Itaconsäure sowie deren saure Ester und Salze. Die Carboxylgruppen können aber nicht nur bei der Polymerisation von Styrol und dem Dien miteingebaut werden, sondern sie können auch nachträglich hinzugefügt werden, z.B. durch Aufpfropfen oder durch eine poly¬ meranaloge Reaktion, wie z.B. Hydrolyse.The basis for the antislip agents according to the invention are therefore copolymers of a diene such as isoprene or butadiene with styrene, which advantageously also contain about 0.5 to 5, preferably 1 to 3, mol% of carboxyl groups in the molecule. Such copolymers can be prepared by polymerization in aqueous dispersion, the third comonomer used being an ethylenically unsaturated compound having a pendant carboxyl group or its substituents. Examples of such comonomers containing carboxyl groups are α, β-ethylenically unsaturated mono- and dicarboxylic acids and their mixtures and salts. Specific examples are acrylic acid, methacrylic acid, maleic acid, fu aric acid, itaconic acid and their acidic esters and salts. The carboxyl groups can not only be incorporated in the polymerization of styrene and the diene, but they can also be added subsequently, e.g. by grafting or by a polymer-analogous reaction, e.g. Hydrolysis.
Die Viskosität des Antislipmittels sollte so sein, daß sie sowohl eine gute Verarbeitung als auch Benetzung ermöglicht. Sie beträgt im allgemeinen 6000 bis 9000 mPa-s (Brookfield Spindel 4; 20 Um¬ drehungen/min; 20 °C). Bei den Verdickern handelt es sich um anio¬ nische wasserlösliche makromolekulare Stoffe, wie z.B. Carboxyl- methylcellulose, Polyacrylsäuren und deren Salze, Alginate, Xanthan Gum und vor allem Copolymerisate von Styrol und Butadien mit einem hohen Gehalt an Carboxylgruppen, insbesondere höher als 5 %.The viscosity of the anti-slip agent should be such that it enables both good processing and wetting. It is generally 6000 to 9000 mPa-s (Brookfield spindle 4; 20 revolutions / min; 20 ° C). The thickeners are anionic water-soluble macromolecular substances, such as Carboxylmethylcellulose, polyacrylic acids and their salts, alginates, xanthan gum and especially copolymers of styrene and butadiene with a high content of carboxyl groups, in particular higher than 5%.
Bei Verwendung des Antislipmittels über längere Zeit empfiehlt es sich ihm noch ein Alterungsschutzmittel hinzuzufügen, z.B. alkylierte Bisphenole, und zwar in einer Konzentration von 0 bis 5, vorzugsweise 0,1 bis 1,0 Gew.-%.If the anti-slip agent is used for a long time, it is recommended to add an anti-aging agent, e.g. alkylated bisphenols, in a concentration of 0 to 5, preferably 0.1 to 1.0 wt .-%.
Der pH-Wert des Antislipmittels wird mit Alkali bzw. Ammoniak auf einen Wert zwischen 8 und 10, vorzugsweise 8,5 und 9,5 eingestellt.The pH of the anti-slip agent is adjusted to a value between 8 and 10, preferably 8.5 and 9.5, with alkali or ammonia.
Vorzugsweise enthält das Antislipmittel keine weiteren Zusätze, insbesondere keine penetrationsfähigen Zusätze wie Weichmacher, Polyvinylmethylether oder Emulgatoren.The antislip agent preferably contains no further additives, in particular no penetrable additives such as plasticizers, polyvinyl methyl ether or emulsifiers.
Der Feststoffgehalt des Antislipmittels beträgt im allgemeinen 40 bis 60 Gew.%, insbesondere 50 bis 55 Gew.%. Er kann jedoch auch außerhalb dieses Bereiches liegen, wenn man z.B. bei niedrigeren Werten eine längere Verdunstungszeit in Kauf nimmt oder bei höheren Werten verkürzt sich die Verdunstungszeit.The solids content of the anti-slip agent is generally 40 to 60% by weight, in particular 50 to 55% by weight. However, it can also lie outside this range if, for example, with lower values a longer evaporation time is accepted or with higher values the evaporation time is reduced.
Die Herstellung des Antislipmittels aus den einzelnen Komponenten ist einfach und bereitet dem Fachmann keine Schwierigkeiten, da sie in gewohnter Weise mit gewr- nten Mitteln durchgeführt wird.The preparation of the antislip agent from the individual components is simple and does not pose any difficulties for the person skilled in the art, since it is carried out in the usual way with the means used.
Das Antislipmittel wird ebenfalls auf bekannte Art und Weise auf die Gegenstände aufgetragen, also z.B. mittels Walzen, Düsen oder Pinsel.The anti-slip agent is also applied to the objects in a known manner, e.g. using rollers, nozzles or brushes.
Die erfindungsgemäßen Antislipmittel eignen sich sowohl zur Ausrü¬ stung von wasseraufsaugenden Gegenständen, aber auch und zwar ins¬ besondere zur Antislipausrüstung von nichtwasseraufsaugenden Ge¬ genständen aus Metallen oder Kunststoffen. Vorzugsweise wird in solchen Fällen das Wasser mit warmer Luft bis 140 °C verdunstet. Zurück bleibt ein klarer, nichtklebriger Film. Dieser Film ist au¬ ßergewöhnlich wasserfest. Zur Bestimmung der Wasserfestigkeit wird eine Glasplatte mit einem 40 Mikrometer dicken Film aus dem Antislipmittel in Wasser bei Raumtemperatur 3 Stunden lang gela¬ gert. Danach sieht der Film unverändert aus, allenfalls ist er leicht grau, auf keinen Fall weiß.The anti-slip agents according to the invention are suitable not only for the equipment of water-absorbent objects, but also and in particular for the anti-slip equipment of non-water-absorbent objects made of metals or plastics. In such cases, the water is preferably evaporated with warm air up to 140 ° C. What remains is a clear, non-sticky film. This film is exceptionally waterproof. To determine the water resistance, a glass plate with a 40 micron thick film is made from the Antislip agent stored in water at room temperature for 3 hours. After that, the film looks unchanged, at most it is slightly gray, by no means white.
Auch die Wärmestandfestigkeit bis zu Temperaturen von 85 °C ist außergewöhnlich hoch. So können samtartige Textilien mit der Flor¬ seite auf einem rutschfest ausgerüsteten Kleiderbügel mit einer Belastung von 400 g / 20 cm2 über 8 Stunden bei 75 °C belastet werden, ohne daß nach der Entfernung des Textils auf dem Kleider¬ bügel Flusen vom Flor zu sehen sind. Auch ist keine Veränderung der Farbe oder des Glanzes auf dem Samt festzustellen.The heat resistance up to temperatures of 85 ° C is also exceptionally high. For example, velvet-like textiles can be loaded with the pile side on a non-slip hanger with a load of 400 g / 20 cm 2 for 8 hours at 75 ° C. without fluff from the pile after removal of the textile on the hanger are seen. There is also no change in color or gloss on the velvet.
Trotz dieser geringen Neigung zum Verkleben ist die rutschhemmende Wirkung besonders kräftig.Despite this low tendency to stick, the anti-slip effect is particularly strong.
Aufgrund dieser Eigenschaften eignet sich das Antislipmittel ins¬ besondere zur Rutschfestausrüstung von Kleiderbügel, insbesondere von Kleiderbügel aus Metall und Kunststoff, wofür zweckmäßigerweise Polystyrol verwendet wird.On the basis of these properties, the anti-slip agent is particularly suitable for the non-slip treatment of clothes hangers, in particular clothes hangers made of metal and plastic, for which purpose polystyrene is expediently used.
In dem speziellen Fall der Rutschfestausrüstung von Kleiderbügel kommt zu den allgemeinen positiven Wirkungen wie Lösungsmittel¬ freiheit, Wärmestabilität und Wasserfestigkeit noch hinzu:In the special case of non-slip finishing of hangers, there are the general positive effects such as freedom from solvents, heat stability and water resistance:

Keine Penetration durch niedermolekulare Additive und damit keine Beeinträchtigung der Farbe und des Glanzes von Textilien. Die Erfindung wird nun anhand eines Beispieles im einzelnen erläu¬ tert:No penetration through low-molecular additives and therefore no impairment of the color and gloss of textiles.

Dann wurden noch 2 Gew.Teile an Wasser hinzu¬ gefügt und wieder bis zur homogenen Verteilung gerührt. Die Visko¬ sität betrug dann 7000 mPa«s (Brookfield, 20 °C). Der pH-Wert lag bei 9,0 und der Festkörpergehalt betrug 52 Gew.%.To 97 parts by weight of a copolymer of styrene and butadiene in a ratio of 40:60, which still contains itaconic acid as a comonomer and is present in the form of a 53% by weight aqueous dispersion with a pH of 8.5, 1 Part by weight of an anionic aqueous dispersion of an anionic copolymer of butadiene and styrene with a high content of carboxyl groups and stirred in conventional devices until homogeneous distribution had occurred (no streaks with a glass spread in a thin layer). Then 2 parts by weight of water were added and the mixture was stirred again until homogeneous. The intensity was then Visko¬ 7000 mPa 's (Brookfield, 20 ° C). The pH was 9.0 and the solids content was 52% by weight.
2. Anwendung2. Application
Das Antislipmittel wurde mit einem Düsenauftragsgerät sowohl auf den Steg als auch an die beiden Schenkel eines Polystyrol-Kleider¬ bügels in einer Menge von ca. 3 g/Bügel bei Raumtemperatur aufge¬ tragen und in warmer Luft von 60 - 80 °C innerhalb von ca. 5 Minu¬ ten getrocknet. Dabei entstand ein klarer, nichtklebriger Film des Polymerisates aus Styrol und Butadien.The antislip agent was applied with a nozzle applicator to both the web and the two legs of a polystyrene hanger in an amount of approx. 3 g / hanger at room temperature and in warm air at 60 - 80 ° C within approx 5 minutes dried. This resulted in a clear, non-sticky film of the polymer made from styrene and butadiene.
3. Eigenschaften3. Properties
a) Der Antislipeffekt wurde bestimmt, indem Hosen mittig auf den Kleiderbügel gehängt wurden und mit einer Federwaage die Kraft bestimmt wurde, bei der sie zum ersten Mal rutschen. Bei der Auswertung müssen hierbei die unterschiedlichen Textilien mit¬ berücksichtigt werden. Es wurden Kräfte gemessen im Bereich von 2 bis 8 kN. b) Zur Bestimmung der Wärmestandfestigkeit wurden samtartige Tex¬ tilien mit der Florseite auf die Bügel aufgebracht und mit 400 g / 20 cm2 8 Stunden bei Temperaturen von 70, 75, 80 und 85 °C belastet. Danach wurde der Samt vom Kleiderbügel entfernt. Die Bewertung erfolgte danach, ob auf dem Kleiderbügel Flusen an¬ haften oder nicht. Im Falle der erfindungsgemäßen Antislipmittel haften bei 80, teilweise sogar bei 85 °C keine Flusen an. c) Die Wasserfestigkeit wurde bestimmt, indem auf einer Glasplatte ein 40 Mikrometer dicker Film des Antislipmittels erzeugt und 24 Stunden bei Raumtemperatur getrocknet wurde. Die so herge¬ stellte Probe wurde 3 Stunden in Wasser von 20 °C gelagert. Die Wasserfestigkeit wurde danach beurteilt, ob die Filme weiterhin transparent waren oder ob sie leicht grau, grau oder gar weiß wurden. Das erfindungsgemäße Slipmittel war leicht grau. a) The anti-slip effect was determined by hanging trousers in the middle of the hanger and using a spring balance to determine the force at which they slip for the first time. In the The different textiles must also be taken into account in the evaluation. Forces were measured in the range from 2 to 8 kN. b) To determine the heat resistance, velvet-like textiles were applied to the temples with the pile side and subjected to 400 g / 20 cm 2 for 8 hours at temperatures of 70, 75, 80 and 85 ° C. The velvet was then removed from the hanger. The evaluation was carried out according to whether fluff adhered to the hanger or not. In the case of the anti-slip agents according to the invention, no fluff adheres at 80, in some cases even at 85 ° C. c) The water resistance was determined by producing a 40 micrometer thick film of the anti-slip agent on a glass plate and drying for 24 hours at room temperature. The sample thus produced was stored in water at 20 ° C. for 3 hours. The water resistance was assessed according to whether the films were still transparent or whether they turned slightly gray, gray or even white. The slip agent according to the invention was slightly gray.
