Description
Verfahren zur Herstellung von pulverförmigem Trockenharzleim Nach Patentanmeldung C 16058 IV a / 23e ist ein Verfahren beschrieben, nach welchem bei Herstellung eines pulverförmigen Trockenharzleimes aus Naturharzen, insbesondere aus Balsam-, Wurzel-oder Tauharzen einerseits und aus einer Lösung eines zur Verseifung geeigneten alkalischen Stoffes andererseits, der auf Schmelztemperatur über 120° C erhitzten Harzschmelze die heiße Lösung des alkalischen Stoffes zur Bildung einer zähen und steif porösen Masse unter inniger Vermischung, z. B. durch Rühren, einverleibt wird.Process for the production of powdered dry resin glue Nach Patent application C 16058 IV a / 23e describes a method according to which in Production of a powdery dry resin glue from natural resins, in particular from balsam, root or dew resins on the one hand and from a solution of one for saponification suitable alkaline substance on the other hand, the melting temperature above 120 ° C heated resin melt the hot solution of the alkaline substance to form a tough and stiff porous mass with intimate mixing, z. B. by stirring, incorporated will.
Die Umsetzung verläuft hierbei in verhältnismäßig kurzer Zeit, so daß in einfachen Misch- und Fördervorrichtungen diese Arbeit bis zur Erzielung eines pulverisierbaren Gutes durchführbar ist. Bei der Durchführung dieses Verfahrens kann man durch entsprechende Auswahl der verwendeten Harzsorten die Beschaffenheit, z. B. Konsistenz des Reaktionsproduktes beeinflussen, z. B. mittels dunklerer Harzsorten die Verzähnung hinausschieben oder auf die jeweiligen Arbeitsbedingungen bei aufzuwendender Arbeitsenergie für die Misch- und Rühreinrichtungen einstellen.The implementation takes place in a relatively short time, see above that in simple mixing and conveying devices this work to achieve one pulverizable good is feasible. When performing this procedure by selecting the types of resin used, the quality, z. B. affect consistency of the reaction product, e.g. B. by means of darker types of resin postpone the gearing or on the respective working conditions at expended Set the working energy for the mixing and stirring devices.
Es ist weiterhin auch durch Verwendung von modifizierten Harzen, z. B. durch Anlagerung von Maleinsäureanhydrid, möglich, besondere Eigenschaften, wie Herabsetzung der Vergilbung, zu erzielen.It is also possible by using modified resins, e.g. B. by addition of maleic anhydride, possible special properties, such as To reduce yellowing.
Es wurde nun in weiterer Ausbildung der Erfindung gefunden, daß sich mit Vorzug auch hydrierte Harze eignen, die die besondere Eigenschaft haben, daß sie nicht zu Vergilbungen führen, da sie keine oxydable Doppelbindungen mehr aufweisen, und daß sie weiterhin ein sehr gutes Verleimungsvermögen der erzielten Harzleime bedingen.It has now been found in a further embodiment of the invention that Hydrogenated resins, which have the special property that they do not lead to yellowing, as they no longer have oxidizable double bonds, and that they continue to have very good gluing properties of the resin sizes obtained condition.
Ausführungsbeispiel 100 g hydriertes Balsamharz werden geschmolzen und auf 140° C erhitzt. In diese Schmelze werden 40 g Natronlauge mit einem Gehalt von 45'°/a Na O H, die vorher auf etwa 60° C erwärmt waren, eingerührt. Die Masse wird beim Rühren zähflüssig, und es findet eine heftige chemische Reaktion statt, bei der Wasser verdampft. Sobald die Reaktion beendet ist, hat die Masse eine spröde, leicht zu pulvernde Form angenommen, die sich rückstandfrei in Wasser auflöst. Aus den 2- bis 0,2o/aigen Lösungen wird mit Aluminiumsulfat eine weiße kleinflockige Fällung erzeugt.Exemplary embodiment 100 g of hydrogenated gum resin are melted and heated to 140 ° C. 40 g of sodium hydroxide solution with a content of of 45 ° / a Na O H, which had previously been heated to about 60 ° C, stirred in. The crowd becomes viscous when stirred, and a violent chemical reaction takes place, when the water evaporates. As soon as the reaction is over, the mass has a brittle, It is easy to powder and dissolves in water without leaving any residue. the end The 2 to 0.2% solutions become white, small flaky with aluminum sulphate Precipitation generated.
