Description

Verfahren zur Herstellung eines wasserlöslichen Eindampfproduktes aus Latex. In weiterer Ausbildung des durch das Patent.419658 geschützten Verfahrens wurde die überraschende Beobachtung gemacht, daß die zur Gewinnung von resolublem Trockenlatex geeigneten Schutzkolloide, u. a. beispielsweise Seifen oder seifenähnliche Körper, in ihrer Wirkung ganz erheblich durch Zugabe von hydrozyklischen Verbindungen aller Art gefördert merden. Besonders haben sich bewährt Tetra-, Hexa-, Methylhexa-, Dekahydronaphthalin und Zyklohexanol. Die zugesetzten Kohlenwasserstoffe wirken durchaus nicht als Lösungsmittel. Es ist bekannt, daß Kohlenwasserstoffe unter Umständen das Emulgierungsvermögen anderer Stoffe steigern können, indem sie als Lösungsmittel Verunreinigungen, welche die Emulgierung hemmen, auflösen und so ausschalten. Bei dem vorliegenden Verfahren wirken die zugesetzten Kohlenwasserstoffe jedoch nicht als Lösungsmittel. Außerdem hemmt ein gutes Lösungsmittel durchaus nicht die Koagulation des dispergierten Stoffes. Setzt man nämlich dem Latex ein spezifisch gutes Lösungsmittel für Kautschuk, wie Benzol, Chloroform usw., in reinem Zustände zu, so tritt Koagulation ein. Es handelt sich also um eine direkte Verstärkung der stabilisierenden Kräfte des zugesetzten Schutzkolloides, die überraschend ist, weil der Zusatz eines Lösungsmittels eine Reifung und dadurch verringerte Stabilität erwarten ließe. Beispiel.Process for the production of a water-soluble evaporation product made of latex. In further development of the process protected by patent 419658 the surprising observation was made that the production of resolublem Protective colloids suitable for dry latex, inter alia. for example soaps or similar ones Body, in their effect quite considerably through the addition of hydrocyclic compounds merden of all kinds. Tetra-, hexa-, methylhexa-, Decahydronaphthalene and cyclohexanol. The added hydrocarbons work not at all as a solvent. It is known that hydrocarbons under certain circumstances can increase the emulsifying power of other substances by using them as solvents Impurities that inhibit emulsification dissolve and thus switch off. at however, the added hydrocarbons have no effect in the present process as a solvent. In addition, a good solvent by no means inhibits coagulation of the dispersed substance. If you add a specifically good solvent to the latex for rubber, such as benzene, chloroform, etc., in the pure state, coagulation occurs a. So it is a direct reinforcement of the stabilizing forces of the added protective colloid, which is surprising because the addition of a solvent a ripening and thus reduced stability could be expected. Example.

Man löst 25 Teile Dekahydronaphthalin in 7 5 Teilen Kaliumoleat auf. Von dieser Lösung trägt man 5 Teile in zoo Teile Latex ein. Dieses Gemisch wird in einem Vakuumtrockner eingedampft und liefert ein Produkt, das in Wasser völlig löslich ist.25 parts of decahydronaphthalene are dissolved in 7.5 parts of potassium oleate. 5 parts of this solution are put into zoo parts of latex. This mixture will Evaporated in a vacuum dryer to yield a product that is totally in water is soluble.
