Description

Verfahren zur Behandlung von Latex oder Latexkonzentraten Wenn man zum Latex in Wasser unlösliche oder schwer lösliche Lösungsmittel für Kautschuk hinzufügt, wie Chloroform, Benzol, Terpentinöl usw., so erfolgt je nach der Natur und Menge des Lösungsmittels mehr oder weniger leicht die Bildung eines zähen Coagulums. Fügt man indessen vorher dem Latex eine gewisse Menge gallenhaltiger Stoffe hinzu, wie beispielsweise frische oder eingedickte Galle usw., so kann man bei Wahl geeigneter Mengenverhältnisse infolge der peptisierenden Eigenschaften der Galle die Coägulation entweder völlig verhindern, oder man erhält ein schwammartiges bzw. gelartiges, sehr labiles Coagulum, welches im Gegensatz zu dem ohne Gallenzusatz erzeugten kompakteren Coagulum verhältnismäßig leicht zu einer viskosen, klebrigen Flüssigkeit oder Paste verreibbar ist, die man u. a. als Klebmittel sowie Imprägniermittel für Holz, Metall und Gewebe und ebenso nach Zusatz von Pigmenten, wie Bleiweiß usw., evtl. auch von Ölen oder Harzen usw. als Anstreichmittel verwenden kann.Method of treating latex or latex concentrates When one Solvents for rubber that are insoluble in water or sparingly soluble in addition to latex adding such as chloroform, benzene, turpentine oil, etc., is done according to the nature and amount of solvent more or less easily results in the formation of a tough coagulum. If, however, a certain amount of bile-containing substances is added to the latex beforehand, such as fresh or thickened bile, etc., one can choose more suitable Amount proportions due to the peptizing properties of the bile cause coegulation either prevent it completely, or you get a sponge-like or gel-like, very labile coagulum, which in contrast to the more compact one produced without the addition of bile Coagulum comparatively easily to a viscous, sticky liquid or paste is friable, which you u. as an adhesive and impregnating agent for wood, metal and tissue and also after the addition of pigments, such as white lead etc., possibly also of May use oils or resins, etc. as a paint.

Dadurch, daß Galle oder gallenhaltige Stoffe die Coagulationsfähigkeit des Latex verhindern bzw. vermindern, bietet sich die :Möglichkeit, den Latex bei Transporten auch ohne Zusatz von Ammoniak vor Coagulation zu schützen. Auch kann man durch Gallenzusatz die Permeabilität des Latex beispielsweise in Häuten erhöhen und somit den Latex für Gerbereizwecke verwerten. Indem man den Gemengen von Latex, Galle und organischen Kautschuklösungsmitteln verschiedene Viskositäten verleihen kann, eignen sich derartige Gemenge besonders gut für Kleb- und Imprägnierzwecke. Bei ihrer Verwendung als Streichmittel ist hinzuweisen auf die peptisierende Wirkung der Galle, welche zur Folge hat, daß beispielsweise Zinkoxyd, Bleiweiß usw. viel feiner verteilt werden als durch andere Streichmittel. Beispiele 5 ccm 25prozentiger Latex wurden mit 3 ccm Benzol versetzt; es erfolgte eine völlige Coagulation des Kautschuks.Because bile or substances containing bile reduce the ability to coagulate To prevent or reduce the latex, there is the possibility of using the latex at To protect transports from coagulation even without the addition of ammonia. Also can the permeability of the latex, for example in skins, can be increased by adding bile and thus use the latex for tanning purposes. By taking the mixture of latex, Bile and rubber organic solvents give different viscosities such mixtures are particularly suitable for adhesive and impregnation purposes. If they are used as a coating agent, reference should be made to the peptizing effect the bile, which has the consequence that, for example, zinc oxide, white lead, etc., a lot be distributed more finely than with other coating agents. Examples 5 cc 25 percent 3 cc of benzene were added to the latex; there was complete coagulation of the Rubber.

5 ccm 25prozentiger Latex wurden mit 0,5 ccm Ochsengalle versetzt und alsdann mit steigenden Mengen Benzol. Erst nach Zusatz von 5 ccm Benzol zeigte sich der Beginn einer Gelbbindung.5 cc of 25 percent latex were mixed with 0.5 cc of ox gall and then with increasing amounts of benzene. Only after the addition of 5 cc of benzene did it show the beginning of a yellow bond.

5 ccm 25prozentiger Latex wurden mit i,o ccm Ochsengalle versetzt. Selbst bei Zusatz von 15 ccm Benzol trat keine Coagulation ein.5 cc of 25 percent latex were mixed with 1.0 cc of ox bile. No coagulation occurred even with the addition of 15 cc of benzene.

Wenn man ioo ccm 3oprozentigen Latex und 50 ccm einer 5prozentigen wäßrigen Lösung eingedickter Galle (von Riedel A.-G.) mit 5o ccm Terpentinöl versetzt, so erhält man nach längerem Schütteln eine gelartige Masse, welche beim Verreiben sich in eine homogene Flüssigkeit verwandelt.If 100 cc of 3% latex and 50 cc of a 5% aqueous solution of thickened bile (from Riedel A.-G.) are mixed with 50 cc of turpentine oil, a gel-like mass is obtained after prolonged shaking, which turns into a homogeneous liquid when rubbed.
