Description

Verfahren zur Herstellung eines Klebstoffs. In dem Patent 323665 ist ein Verfahren zur Herstellung eines Klebstoffs beschrieben, welches darin besteht, daß Formaldehyd und Dicyand'iamid im Beisein von Schwefelsäure zur Kondensation gebracht wird.Method of making an adhesive. In the patent 323665 is a method for producing an adhesive described, which consists in that formaldehyde and dicyandiamide in the presence of sulfuric acid for condensation is brought.

Weitere Versuche mit Kondensationsprodukten aus Formaldehyd und Dicyandiamid haben nun ergeben, d!aß auch andere Kondensationsmittel, wie sonstige Mineralsäuren, organische Säuren, säureabspaltende und wasserentziehende Salze, die beiden Komponenten zu einer leimigen. Substanz kondensieren. Bei genügend langem Erhitzen erhält man derartige Substanzen auch ganz ohne Kondensationsmittel. Bevor die leimige Substanz entsteht, ist das Kondensationsprodukt eine ölige, sämige Flüssigkeit, die sich als. Ersatt für Glyzerin- und andere geschmeidig machende Substanzen vorzüglich eignet.Further experiments with condensation products from formaldehyde and dicyandiamide have now shown that other condensation agents, such as other mineral acids, organic acids, acid-splitting and dehydrating salts, the two components to a glutinous one. Condense substance. If heated long enough, one obtains such substances even without condensation agents. Before the glutinous substance arises, the condensation product is an oily, creamy liquid that is as. An excellent substitute for glycerine and other emollient substances suitable.
