Hannover, den 17.2.1975 pat ht-laHanover, February 17, 1975 pat ht-la
Klebstoff mit IndikatorfarbstoffAdhesive with indicator dye
In der Patentanmeldung P 24 45 715.6 wird ein in der Masse angefärbter Kleber, insbesondere zur Verwendung als Klebmittel für Papier unter Schutz gestellt, der in der Masse gefärbt ist, nach dem Aufstrich auf Papier jedoch seine Färbung alsbald ganz oder überwiegend verliert. Nach weiteren Merkmalen dieser Patentanmeldung soll der Kleber alkalisch eingestellt sein und mittels eines im alkalischen Bereich farbigen Indikatorfarbstoffes versetzt sein, der bei Berührung mit alkali-adsorbierenden Medien in seine farblose Phase umschlägt. Vorzugsweise soll dem Kleber Calciumhydroxid als Alkali beigegeben sein. Der Kleber soll als Indikatorfarbstoff beispielsweise Thymolphtalein, Phenolphthalein oder Xylenolphthalein einzeln oder in Mischungen miteinander in alkoholischer Lösung enthalten.In the patent application P 24 45 715.6 an adhesive colored in the mass, in particular for use placed under protection as an adhesive for paper, which is colored in the mass, after the spread on However, paper soon loses its color completely or predominantly. According to further features of this patent application the adhesive should be made alkaline and colored in the alkaline range Indicator dye, which turns colorless on contact with alkali-adsorbing media Phase changes. Calcium hydroxide should preferably be added to the adhesive as an alkali. The glue should as an indicator dye, for example, thymolphthalein, phenolphthalein or xylenolphthalein individually or in Mixtures with each other in alcoholic solution.
Es hat sich gezeigt, daß der Übergang des Indikatorfarbstoffes, der in dem Kleber enthalten ist, in seine farblose Phase mit der Zeit auch unter Einwirkung der Luft erfolgen kann, jedenfalls teilweise, und daß damit ein Verblassen der Masse verbunden ist, die zu Unansehnlichkeit des Produktes führt. Es ist gefunden wor^- den, daß man diesen Mangel beseitigen kann, indem man zur Verbesserung der Haltbarkeit der Färbung der Masse 1 - 3 % Triethanolamin oder Triisopropylamin hinzusetzt. It has been shown that the transition of the indicator dye, which is contained in the adhesive, in its colorless phase can take place over time under the action of the air, at least partially, and that this is associated with a fading of the mass, which leads to unsightly Product leads. It has been found that this deficiency can be eliminated by adding 1-3 % triethanolamine or triisopropylamine to improve the durability of the coloration of the mass.
Einen Flüssigkleber stellt man somit erfindungsgemäß nach etwa folgender Rezeptur her:A liquid adhesive is thus produced according to the invention according to the following recipe:
609837/0806609837/0806
2 Teile Triäthanolamin werden mit 3 Teilen Calciumoxid und 30 Teilen Wasser verrührt. Anschließend wird in der alkalischen Flüssigkeit ein Teil Phenolphtalein unter Rühren kalt gelöst. Die dunkelrote Lösung wird langsam in 964 Teilen einer 40%igen Gummiarabicumlösung eingerührt. 2 parts of triethanolamine are mixed with 3 parts of calcium oxide and stirred up 30 parts of water. Then a part of phenolphthalein is added to the alkaline liquid Stirring dissolved cold. The dark red solution is slowly stirred into 964 parts of a 40% gum arabic solution.
Eine Klebmasse, die als Klebstift verwendet werden kann, wird beispielsweise nach folgender Rezeptur hergestellt:An adhesive that can be used as a glue stick is made, for example, according to the following recipe:
15 Teile Triisoprophylamin werden mit 15 Teilen Wasser und 3 Teilen Calciumoxid zu einer Dispersion angerührt. Nachdem 1 Teil Thymolphthalein eingetragen worden ist, wird bis zur vollständigen Lösung gerührt.15 parts of triisopropylamine are mixed with 15 parts of water and 3 parts of calcium oxide to form a dispersion. After 1 part of thymolphthalein has been entered, is stirred until completely dissolved.
Die dunkelblaue Lösung wird zu 966 Teilen einer bei 60 0C verflüssigten Klebstiftmasse unter langsamem Rühren hinzugefügt. Anschließend kann die Masse in die vorbereiteten Hülsen gegossen werden, um darin zu erstarren. The dark blue solution is added to 966 parts of a liquefied at 60 0 C Klebstiftmasse with slow stirring. The mass can then be poured into the prepared pods to solidify in them.
