Description

Klebstoffe Als Klebstoffe für technische Zwecke werden in den verschiedensten Industriezweigen die in Betracht kommenden Ausgangsmaterialien, wie Stärke, Dextrin, Leim, natürliche Gummiarten u. dgl., zumeist in roher, nicht besonders präparierter Form verwendet. Die meisten Verwendungszwecke erfordern möglichst billige Ausgangsstoffe, so daß die erwähnten Materialien nicht in unmittelbar gebrauchsfertigem Zustand, ferner nicht in der haltbaren Form und mit der guten Streichfähigkeit wie die für Bürozwecke beispielsweise im Handel befindlichen Klebstoffe zur Anwendung gelangen.Adhesives As adhesives for technical purposes are used in the most diverse Branches of industry the starting materials to be considered, such as starch, dextrin, Glue, natural types of rubber and the like, mostly raw, not specially prepared Shape used. Most uses require the cheapest possible starting materials, so that the materials mentioned are not in an immediately ready-to-use condition, furthermore not in the durable form and with the good spreadability as the one for Office purposes, for example, commercially available adhesives are used.

Es wurde nun gefunden, daß man technische Klebstoffe wesentlich verbessern kann, wenn man ihnen höhermolekulare Alkohole mit mindestens 6 Kohlenstofatomen zusetzt. Die Quellfähigkeit der verwendeten Ausgangsmaterialien wird bedeutend erhöht, so daß sich übermäßiges Erhitzen bei der Bereitung von Leimlösungen, Stärkekleistern u. dgl., das häufig eine unerwünschte Beeinträchtigung des Klebevermögens dieser Stoffe verursacht, vermeiden läßt. Abgesehen davon lassen sich die gebräuchlichen Klebstoffe wesentlich rascher in gebrauchsfertigem Zustand herstellen. Der Zusatz der höhermolekularen Alkohole wirkt sich ferner in einer überrasch enden Verbesserung der Streichfähigkeit aus. Geeignete, zur Anwendung des vorliegenden Verfahrens brauchbare Ausgangsstoffe sind alle für Klebzwecke in Betracht kommenden Stärkearten, wie Kartoffel-, Weizen-, Reisstärke ü. dgl. Ferner können alle Leimsorten, außerdem Agar-Agar, Gelatine und ähnliche eiweißhaltige Substanzen Anwendung finden. Auch die natürlich vorkommenden Gummiarten, wie Gummiarabikum, Tragant- und Kirschgummi, können in der gekennzeichneten Weise verbessert werden.It has now been found that technical adhesives can be improved significantly can, if you give them higher molecular weight alcohols with at least 6 carbon atoms clogs. The swelling capacity of the raw materials used is significantly increased, so that excessive heating in the preparation of glue solutions, starch paste and the like, which often undesirably deteriorate the adhesiveness of these Causes substances, lets avoid. Apart from that, the common Produce ready-to-use adhesives much faster. The addition the higher molecular weight alcohols also results in a surprising improvement the spreadability. Suitable ones useful for applying the present method The starting materials are all types of starch that can be used for gluing purposes, such as potatoes, Wheat starch, rice starch Like. Furthermore, all types of glue, also agar-agar, gelatin and similar protein-containing substances are used. Even the naturally occurring ones Types of gum, such as gum arabic, tragacanth and cherry gum, can be identified in the Way to be improved.

Die in Betracht kommenden höhermolekularen Alkohole sind in erster Linie die höhermolekularen Fettalkohole, wie beispielsweise die durch Reduktion von Kokosfett erhältlichen Alkohole, ferner Wollfett- und Naphthenalkohole. Auch höhernolekulare ungesättigte Alkohole, wie Oleinalkohol, ferner mehrwertige Alkohole, wie das durch Reduktion von Rizinusöl erhältliche Dioxyoctadecen, können Verwendung finden. Die gemäß vorliegendem Verfahren verbesserten Klebstoffe können zu allen üblichen technischen Verwendungszwecken, . wie bei der Kartonnagefabrikation, zu Appreturzwecken, in der holzverarbeitenden Industrie u. dgl., Verwendung finden:. Beispiel z Einei wässerigen Knochenleimlösung werden vor ihrer Verarbeitung unter schwachem Erwärmen o,5 % Laurinalkohol zugesetzt. Der Zusatz wirkt sich in einer verbesserten Streichfähigkeit aus.The higher molecular weight alcohols to be considered are first Line the higher molecular weight fatty alcohols, such as those produced by reduction alcohols obtainable from coconut oil, as well as wool fat and naphthene alcohols. Even higher molecular weight unsaturated alcohols, such as oleic alcohol, also polyhydric alcohols, such as dioxyoctadecene obtained by reducing castor oil, can be used Find. The adhesives improved in accordance with the present process can be used for all usual technical purposes,. as in cardboard production, too Finishing purposes, in the woodworking industry and the like, are used :. Example z An aqueous bone glue solution is taken before processing weak Warming 0.5% lauric alcohol added. The addition works results in improved spreadability.

Beispiel a Durch Zusatz von 3 % einer Mischung von gleichen Teilen Naphthenalkohol und hochsulfoniertem Türkischrotöl zu einer Gummiarabikumlösung wurde ein Klebstoff erhalten, der eine wesentlich größere Klebkraft als eine reine Gummiarabikumlösung zeigte.Example a By adding 3% of a mixture of equal parts Naphthenic alcohol and highly sulfonated Turkish red oil to a gum arabic solution an adhesive was obtained that had a significantly greater bond strength than a pure one Gum arabic solution showed.
