Description

Verfahren zur Herstellung von Gummilösungen. Eine Reihe von Flüssigkeiten, wie Trichlor äthylen, ist zur Herstellung von Gummilösungen deshalb nicht geeignet, weil diese Körper zu geringes Lösungsvermögen haben und zur Bildung von technisch wertlosen Gallerten neigen. Andere Lösungsmittel, wie Benzin, geben zwar konzentriertere Lösungen, :loch handelt es sich hierbei um Präparate von nicht genügender Klebkraft. Es hat sich nun gezeigt, daß man bei denjenigen Lösungsmitteln, die ungenügendes Lösungsvermögen für Gummi haben, die Löslichkeit in überraschender Weise durch Zusatz der Ester mehrwertiger Alkohole, z. B. der Acetine, erhöhen kann, und daß die Gummilösungen, aus beliebigen Lösungsmitteln hergestellt, bei Gegenwart dieser Ester eine erhöhte Elastizität und Klebkraft erhalten.Process for the production of rubber solutions. A range of liquids like trichlorethylene, is therefore not suitable for the production of rubber solutions, because these bodies have too little solvent power and for the formation of technical worthless jelly. Other solvents, such as gasoline, are more concentrated Solutions,: loch these are preparations with insufficient adhesive strength. It has now been shown that with those solvents that are insufficient Have solvency for rubber, the solubility in a surprising way through addition the esters of polyhydric alcohols, e.g. B. the acetine, and that the rubber solutions, made from any solvent, in the presence of these esters an increased Maintain elasticity and adhesive strength.

Beispiele: I. Ioo g ungewalzter Gummi wird mit I boo g Lösungsbenzin und 0,5 g Diacetin (bz«-. Triacetin) der Quellung überlassen und alsdann in bekannter Weise zu einer homogenen, kolloidalen Lösung verrührt.Examples: I. 100 g of unrolled gum is left to swell with 100 g of mineral spirits and 0.5 g of diacetin (bz «-. Triacetin) and then stirred in a known manner to form a homogeneous, colloidal solution.

a. TOD- ungewalzter Gummi wird mit a4oo g Trichloräthylen und o,5 g Diacetin (bzw. Triacetin) der Ouellung überlassen und alsdann in bekannter `reise zu einer homogenen, kolloidalen Lösung verrührt.a. TOD unrolled rubber is left in the quench with 400 g of trichlorethylene and 0.5 g of diacetin (or triacetin) and then stirred in a known manner to form a homogeneous, colloidal solution.

Statt der Acetine können auch andere Ester der mehrsäurigen Alkohole, z. B. Butyrine, ()leine. Benzoine u-%v. verwendet «-erden.Instead of acetins, other esters of polyacid alcohols, z. B. Butyrine, () leine. Benzoine u-% v. used «-erden.
