Description

Verfahren zur Verbesserung der Trockenfähigkeit trocknender Öle Zur Erhöhung der Trockenfähigkeit pflanzlicher Öle verwendet man gewöhnlich Sikkative, unter denen geeignete Metallsalze im Vordergrund stehen. Oxyd'ative Vorgänge ider Molekülvergrößerung können aber auch nach der Trocknung anhalten und dann den destruktiven Abbau des Anstrichfilms beschleunigen.Process for improving the drying properties of drying oils Zur To increase the drying ability of vegetable oils, siccatives are usually used, among which suitable metal salts are in the foreground. Oxidative processes ider Molecular enlargement can also stop after drying and then the destructive one Accelerate degradation of the paint film.

Es wurde nun gefunden, daß ein Zusatz von Carotinoiden d.ie Trocknung erheblich beschleunigt. Sie müssen, wenigstens in geringem Umfang, fettlöslich sein. Meist genügen Zusätze von Milligrammprozenten, um die gewünschte Wirkung zu erzielen. Besonders stark wird die Trocknung von Fetten mit konjugiert-ungesättigten Fettsäuren beeinflußt, wie z. B. Holzöl, Oiticicaöl oder Öle, welche die 9,rz-Linolsäure enthalten. Um Inhibitole auszuschalten, werden die Öle zweckmäßig vorher raffiniert.It has now been found that the addition of carotenoids d. The drying accelerated considerably. They must be fat-soluble, at least to a small extent. In most cases, additions of milligram percent are sufficient to achieve the desired effect. The drying of fats with conjugated-unsaturated fatty acids becomes particularly strong affects such. B. wood oil, oiticica oil or oils containing the 9, rz-linoleic acid. In order to switch off inhibitols, the oils are expediently refined beforehand.

Der Chemismus der sich bei der Molekülvergrößerung .abspielenden Vorgänge ist noch nicht restlos geklärt. Unter den physikalischen Faktoren ist die Lichtwirkung von Bedeutung. Aber auch die mehrfachen, Bind.;un.gen scheinen eine Rolle zu spielen, denn das aus Carotin gebildete Vitamin A und seine Ester entfalten die gleiche Wirkung. Beispiele r. Raffiniertes Holzöl versetzt man, mit o,oo5 % Carotin. Vergleicht man das ursprüngliche Präparat mit dem unter Zusatz von Carotin gewonnenen, so trocknet fetzteres bei genau gleichen. Bedingungen viermal: schneller.The chemistry of the processes that take place when the molecule enlarges has not yet been fully clarified. Among the physical factors is the effect of light significant. But also the multiple, bind.; Un.gen seem to play a role, because the vitamin A formed from carotene and its esters have the same effect. Examples r. Refined wood oil is mixed with 0.05% carotene. If you compare the original preparation with the one obtained with the addition of carotene, see above dries the latter with exactly the same. Conditions four times: faster.

z. Oiticicaöl, in Lösung raffiniert, trocknete in dünnem Aufstrich in 4 Stunden.. Ein Zusatz von o,oo5 0% Carotin verringerte die Trockenzeit bei sonst ,gleichen Bedingungen auf .die Hälfte.z. Oiticica oil, refined in solution, dried in a thin spread in 4 hours .. An addition of o, oo5 0% carotene reduced the drying time otherwise , equal conditions on .the half.

3. Konjugiertes Leinöl oder raffiniertes Holzöl versetzt man mit o,o1% Vitamin-A-palmitat. Dieser Zusatz beschleunigt die Trocknung um ein Mehrfaches. .3. Conjugated linseed oil or refined wood oil is mixed with o, o1% Vitamin A palmitate. This addition accelerates the drying process several times over. .
