Zusatz zum Patent 471Addendum to patent 471
Patentiert im Deutschen Reiche vom 4. September 1929 ab Das Hauptpatent hat angefangen am 12. Mai 1926.Patented in the German Empire on September 4, 1929 The main patent started on May 12, 1926.
Es ist bekannt, daß sich polymere Vinylester als Klebstoffe eignen. Es ist weiterhin bekannt, daß auch Celluloseester klebende Eigenschaften haben. Es wurde nun gefunden, daß überraschenderweise bei der Kombination beider Klebstoffe nicht etwa Massen entstehen, deren Klebwirkung sich aus der Klebwirkung der Komponenten additiv zusammensetzt, sondern Massen, deren Kleb-ο wirkung in nicht vorherzusehender Weise gesteigert ist. Die Klebkraft der einen Komponente ändert sich im Sinne einer sprunghaften Steigerung schon dann, wenn der Zusatz an dem zweiten Stoff nur sehr gering ist.It is known that polymeric vinyl esters are suitable as adhesives. It is still known that cellulose esters also have adhesive properties. It has now been found that, surprisingly, when the two adhesives are combined, there are no masses whose adhesive action results from the Adhesive effect of the components additively composed, but masses whose adhesive ο effect is increased in an unforeseeable way. The bond strength of one component changes in the sense of a sudden increase when the addition of the second substance is only very small.
tS Dieses eigenartige und technisch höchst wertvolle Verhalten der Kombinationen ist aus den Angaben der Literatur über die beispielsweise aus der österreichischen Patentschrift 70 348 an sich bekannten Mischungen vontS This peculiar and technically highly valuable Behavior of the combinations is from the information in the literature on the example from Austrian patent specification 70 348 known mixtures of
Polyvinylestern und Celluloseestern nicht zu entnehmen, da diese entweder überhaupt nichts über die Klebwirkung enthalten oder nicht offenbaren, daß der Zusatz von Celluloseestern zu Polyvinylestern eine überraschende Steigerung der Klebkraft ergibt.Polyvinyl esters and cellulose esters cannot be found either, as they are at all contain nothing about the adhesive effect or do not disclose that the addition of cellulose esters to polyvinyl esters results in a surprising increase in bond strength.
Streifen aus Ziegenleder von 3 χ 13 cm Ausdehnung wurden mit den nachstehend' angegebenen Lösungen bzw. Lösungskombinationen auf Aluminiumblech geklebt. Nach einer Trockenzeit von 67 Stunden wurde das eine mit einem Loch versehene Ende des Lederstreifens mit einer darunter befindlichen Schale verbunden, die allmählich immer mehr belastet wurde, bis bei einer bestimmten Belastung das Leder von Aluminium abgerissen wurde.Strips of goatskin with an extension of 3 × 13 cm were glued to aluminum sheet using the solutions or combinations of solutions given below. After a drying time of 67 hours, one end of the leather strip provided with a hole was connected to a shell underneath, which was gradually subjected to more and more stress, until the leather was torn from the aluminum at a certain load.
