Description

Klebstoff auf Wasserglasgrundlage Es ist bekannt, Wasserglas als Grundsubstanz zur Herstellung von Klebstoffen zu verwenden. Hierbei werden dem Wasserglas Zusätze anorganischer oder organischer Art gegeben, um seine Eigenschaften zu verbessern. Solche Zusätze sind z. B. Phosphate, Harnstoffe, Benzoesäureanhydrid, Bariumoxyd usw. Diese Zusätze machen stets einen nennenswerten Prozentsatz, bezogen auf das Wasserglas, aus und betragen fast immer ungefähr Io bis I5%.Water glass based adhesive It is known to use water glass as a basic substance to be used for the production of adhesives. Here, additives are added to the water glass inorganic or organic type given to improve its properties. Such additives are z. B. phosphates, ureas, benzoic anhydride, barium oxide etc. These additives always make up an appreciable percentage based on the Water glass, and are almost always around Io to 15%.

Die bekannten Klebstoffe aus Wasserglas neigten häufig zu sogenännten Alterungs erscheinungen. Es hat sich nun gezeigt, daß aus Wasserglas unter Zusatz äußerst geringer Mengen gewisser phenolischer Körper, vor allem solcher, welche noch mit einem hydroaromatischen Kern verbunden sind, z. B. o-Cyclohexylphenol und Dicyandiamid, überraschenderw eise Klebstoffe erhalten werden, welche im Gegensatz zu den bisher bekannten, auf Wasserglasgrundlage aufgebauten Klebstoffen für viele Zwecke Verwendung finden können. Als phenolische Körper kommen außer den genannten noch in Betracht Phenol selbst, ferner Substanzen der allgemeinen Formel: wobei R und R1 Substituenten aliphatischer Natur sind und 1 einen hydroaromatischen Kern bedeutet. Durch den Zusatz. der phenolischen Körper wird ferner eine fäulnishemmende Wirkung erreicht. Der gemäß der vorliegenden Erfindung hergestellte Klebestoff dient zum Kleben von Holz, imprägnierten und anderen Pappen, Glas, Porzellan, Steingut usw.The known adhesives made from water glass often showed signs of aging. It has now been shown that from water glass with the addition of extremely small amounts of certain phenolic bodies, especially those which are still connected to a hydroaromatic core, e.g. B. o-Cyclohexylphenol and dicyandiamide, surprisingly, adhesives are obtained which, in contrast to the previously known adhesives based on water glass, can be used for many purposes. In addition to those mentioned, phenol itself, further substances of the general formula: where R and R1 are substituents of aliphatic nature and 1 denotes a hydroaromatic nucleus. By adding. the phenolic body also has an anti-fouling effect. The adhesive produced according to the present invention is used for gluing wood, impregnated and other cardboard, glass, porcelain, earthenware, etc.

Es ist von Vorteil, zur besseren Emulgierurig des o-Cyclohexylphenols eine gleich grolle Menge einer aromatischen Sulfosäure odler eines Esters einer solchen demn Wasserglas zuzusetzen.It is advantageous for better emulsification of the o-cyclohexylphenol one the same large amount of an aromatic sulfonic acid or one To add esters to such a water glass.

Beispiel Iooo g Wasserglas (4o° Be), b g lbenzolstulfonsatures Äthyl, 6g o-Cyclohexylphenol, 4o g Dicyandliamid werden hei 33 bis d0° unter Rühren gemischt, his eine gleichmäßig getrübte homnogene Mischung entstellt.Example Iooo g water glass (40 ° Be), b g lbenzolstulfonsatures ethyl, 6 g of o-cyclohexylphenol, 40 g of dicyandliamide are mixed at 33 to d0 ° with stirring, until an evenly cloudy homogeneous mixture is distorted.

Der auf die angegebene Weise hergestellte Klebstoff ist sofort gebrauchsfertig und kann ohoe weitere Zusätze verwendet werden. Der Klebstof gemüiß der Erfindung kann natürlich, falls notwentlg, durch Zusatz voll Farbstoffen gefärbt werden.The adhesive produced in the manner indicated is ready for immediate use and ohoe other accessories can be used. The adhesive according to the invention can of course, if necessary, be colored by adding full dyes.
