Description
Klebstofflösung oder lackähnliche Masse Beim Auftragen von Klebstofflösungen oder lack ähnlichen Massen auf Flächen, Kanten oder Latten macht der Umstand sehr oft Schwierigkeiten, dass bei ähnlicher Farbe der Klebstofflösung oder des Lackes und der Unterlage oder infolge ihrer Transparenz die notwendige Auftragmenge schwer geschätzt werden kann. Besonders grosse Schwierigkeiten entstehen bei Auftragmethoden, wie z. B. beim Spritzen, wo die pro Flächeneinheit aufgetragene Menge von der Zeit, einer Düsenöffnung oder dem Druck abhängig sind.
Ferner überall dort, wo durch schlechte Belichtungs-Verhält- nisse die aufgetragene Menge schwer zu erkennen ist, wie z. B. auf einem an einer Decke angebrachten Latten rost.
Ein Anfärben bringt beim Klebstoff den Nachteil mit sich, dass sichtbare Klebfugen ungewollt durch ihre Eigenfarbe hervortreten und dass bei einem Lack unge wollte Farbeffekte entstehen. Ferner kann gefärbter Klebstoff bei dünnen Materialien durchscheinen.
Gegenstand der Erfindung bildet nun eine Kleb stofflösung oder eine lackähnliche Masse, die beim Aufbringen auf die Unterlage einen deutlich sichtbar machenden Farbstoff enthält, der beim Auftrocknen infolge pH-Änderung eine neue, weniger intensive Farbe annimmt oder seine Farbe verliert. Die pH-Änderung kann z. B. bedingt sein durch die Einwirkung von Luftfeuchtigkeit, Kohlensäure oder Sauerstoff. Dabei kann der Farbstoff einen dem Untergrund angepassten Farbton annehmen, so dass er bei sichtbaren Fugen nicht mehr stört.
Die Farbänderung kann auch erzielt werden, indem man eine flüchtige Säure oder Base beisetzt, nach deren Verdunstung eine pH-Änderung den gewünschten Farbumschlag bewirkt.
In den nachfolgenden Beispielen wird eine 20 % ige Polychloroprenlösung in Methyläthylketon : Toluol : Benzin = 1 : 1 : 1 verwendet, die auf Polychloropren bezogen 5 % Mg0 enthält. Selbstverständlich können die Beispiele auch auf Lacke oder lackähnliche Massen angewendet wer den. <I>Beispiel 1</I> 100 Teile Polychloroprenlösung, wie oben beschrieben, werden mit 2 Teilen 0,4 % iger Bromthymolblau-Lösung ver setzt.
Beim Spritzen an Luft mit mindestens 30 % rela tiver Feuchtigkeit färbt sich die Masse auf der Unter lage violett und wechselt an der Luft allmählich über grün nach gelb. Setzt man 0,3 % Oxalsäure zu, tritt an stelle der Violettfärbung eine intensive Blaufärbung ein, die ebenfalls über grün nach gelb verschwindet.
<I>Beispiel 2</I> 100 Teile Polychloroprenlösung, wie oben beschrieben 0,4 Teile Oxalsäure 2,0 Teile Bromthymolblau 0,4 % ig in MEK Der Klebstoff hat eine gelbgrüne Farbe, trifft beim Spritzen auf der Unterlage intensiv grünblau auf, wech selt an der Luft innert einer Stunde nach grün und ist am anderen Tag hellgelb.
<I>Beispiel 3</I> 500 Teile obiger Polychloroprenlösung 10 Teile Phenolphthalein 1 % ig in MEK 10 Teile Äthylamin 70 % ig in Wasser Beim Spritzen dieses Klebstoffes an Luft mit minde stens 50 % relativer Feuchtigkeit trifft der Klebstoff auf der Unterlage intensiv rot auf und wechselt innert 10 Minuten nach farblos.
<I>Beispiel 4</I> 450 Teile obiger Polychloroprenlösung 9 Teile Phenolphthalein 1 % ig in MEK 2 Teile Wasserglaslösung 40 B6 Das Wasserglas muss mit einem Schnellrührer ein gerührt werden, da sich sonst der Farbstoff nicht gleich mässig verteilt. Beim Spritzen erscheint dieser Klebstoff rosarot und wechselt innert einiger Tage nach einem ganz schwachen Rosa. <I>Beispiel 5</I> Wie Beispiel Nr. 4. Anstelle von Wasserglas wird jedoch Ammoniak-Gas in die Lösung eingeleitet, bis sie sich blaugrün verfärbt.
Das Ammoniak-Gas kann auch separat in eines der verwendeten Lösungsmittel eingeleitet werden.
<I>Beispiel 6</I> 100 Teile Polychloropren-Lösung 2 Teile Bromthymolblau 1 % ig in MEK 0,5 Teile NaOH 25 % in Wasser 3,5 Teile Benzoesäure 15 % ig in MEK Nach dem Spritzen oder Aufstreichen mit Spachtel oder Pinsel ist die aufgebrachte Lösung blaugrün. Die Farbe verschwindet an der Luft nach etwa 10 Minuten.
Um eine intensive Farbe zu erhalten, ist es nötig, dass -diese in den Lösungsmitteln löslich ist. Sofern Säuren oder Basen zur Anwendung kommen, muss ebenfalls von diesen Zusätzen Löslichkeit in den ver wendeten Lösungsmitteln verlangt werden oder dann müssen die mit den Lösungsmitteln nicht mischbaren Zusätze einemulgiert werden, zweckmässigerweise unter Verwendung eines Emulgiermittels.
Adhesive solution or lacquer-like mass When applying adhesive solutions or lacquer-like masses to surfaces, edges or laths, the fact that it is difficult to estimate the amount of application required if the adhesive solution or the lacquer and the substrate are similar in color or due to their transparency is difficult. Particularly great difficulties arise with application methods such as B. when spraying, where the amount applied per unit area depends on the time, a nozzle opening or the pressure.
Furthermore, wherever the amount applied is difficult to see due to poor exposure conditions, such as B. grate on a slat attached to a ceiling.
In the case of adhesives, coloring has the disadvantage that visible glue joints unintentionally emerge due to their inherent color and that unwanted color effects arise in the case of a lacquer. Also, colored glue can show through with thin materials.
The invention now forms an adhesive material solution or a paint-like mass that contains a clearly visible dye when applied to the substrate, which takes on a new, less intense color or loses its color when drying due to pH change. The pH change can e.g. B. be caused by the action of humidity, carbonic acid or oxygen. The dye can take on a color that matches the substrate so that it no longer interferes with visible joints.
The color change can also be achieved by adding a volatile acid or base, after the evaporation of which a pH change brings about the desired color change.
In the following examples, a 20% polychloroprene solution in methyl ethyl ketone: toluene: gasoline = 1: 1: 1 is used, which contains 5% MgO based on polychloroprene. Of course, the examples can also be applied to lacquers or lacquer-like compositions. <I> Example 1 </I> 100 parts of polychloroprene solution, as described above, are mixed with 2 parts of 0.4% strength bromothymol blue solution.
When spraying in air with at least 30% relative humidity, the mass on the surface turns purple and changes gradually from green to yellow in the air. If 0.3% oxalic acid is added, instead of the violet coloration, an intense blue coloration occurs, which also disappears via green to yellow.
<I> Example 2 </I> 100 parts of polychloroprene solution, as described above 0.4 parts of oxalic acid 2.0 parts of bromothymol blue 0.4% in MEK The adhesive has a yellow-green color, when it is sprayed it hits the surface with an intense green-blue, changes to green within an hour in the air and is light yellow the next day.
<I> Example 3 </I> 500 parts of the above polychloroprene solution 10 parts phenolphthalein 1% in MEK 10 parts ethylamine 70% in water When this adhesive is sprayed in air with at least 50% relative humidity, the adhesive on the base hits an intense red and changes to colorless within 10 minutes.
<I> Example 4 </I> 450 parts of the above polychloroprene solution 9 parts phenolphthalein 1% in MEK 2 parts water glass solution 40 B6 The water glass must be stirred in with a high speed stirrer, otherwise the dye will not be evenly distributed. When sprayed, this adhesive appears rose-red and changes to a very faint pink within a few days. <I> Example 5 </I> As for example no. 4. Instead of water glass, however, ammonia gas is passed into the solution until it turns blue-green.
The ammonia gas can also be introduced separately into one of the solvents used.
<I> Example 6 </I> 100 parts of polychloroprene solution 2 parts of bromothymol blue 1% in MEK 0.5 parts of NaOH 25% in water 3.5 parts of benzoic acid 15% in MEK After spraying or spreading with a spatula or brush the applied solution is blue-green. The color disappears in the air after about 10 minutes.
In order to obtain an intense color, it is necessary that it is soluble in the solvents. If acids or bases are used, solubility in the solvents used must also be required of these additives, or the additives which are immiscible with the solvents must then be emulsified, advantageously using an emulsifying agent.
