Description

Verfahren zur Herstellung von Schutzanstrichen Wenn man Emulsionen zu Anstrichzwecken verwendet, so muß man Wert darauf legen, daß die Emulsion getrocknet ist, d. h. daß der Wassergehalt seiner Emulsion, wenn. es sich um wässerige Emulsionen handelt, oder der Spiritusgehalt bei Spiritusemulsionen usw. verdunstet ist, ehe der Anstrich seine Schutzwirkung ausüben 'soll, d. h. ehe der Anstrich dem Wasser oder sonstigen angreifenden =Wirkungen ausgesetzt wird.Process for the preparation of protective paints When using emulsions When used for painting purposes, care must be taken to ensure that the emulsion is dried is, d. H. that the water content of its emulsion, if. they are aqueous emulsions or the alcohol content of alcohol emulsions etc. has evaporated before the paint should exert its protective effect, d. H. before the painting to the water or other aggressive = effects.

Nun hat sich gezeigt, daß ein Ölfilm auf Emulsionsschichten die schädlichen Einwirkungen einer vorzeitigen Benetzung durch Feuchtigkeit aufhebt, so daß die Emulsionen austrocknen und erhärten können, ohne daß sie durch vorzeitige Benetzung in unzulässiger Weise verdünnt oder beschädigt werden.It has now been shown that an oil film on emulsion layers is the most damaging Cancels the effects of premature wetting by moisture, so that the Emulsions can dry out and harden without affecting them through premature wetting diluted or damaged in an inadmissible manner.

Wenn man z. B. Gäsbehälterwände, die ins Sperrwasser tauchen, mit einer Emulsionsfarbe überzieht, und auf das Sperrwasser Mineralöl aufgießt, so wird die Emulsionsfarbe bei unvorhergesehenem Eintauchen des Behälters ins Sperrwasser sich zunächst mit dem darauf schwimmenden Öl überziehen. Das Emulsionswasser bleibt dann zunächst im Anstrichfihn, bis es beim Austauchen des Gasbehälters an der Luft allmählich verdunstet. Selbstverständlich müssen solche Emulsionen mit -entsprechend geringem Wassergehalt zu-.bereitet und so stabil sein, daß sie durch die Benetzung mit Öl keinen Schaden leiden, was aber bei der heutigen Emulsionstechnik ahne weiteres möglich ist. Es ist auch möglich, äeraitige Emulsionen auf Flächen aufzutragen, die vorher geölt waren, wenn man nur dafür sorgt, daß der Ölfilm auf der Streichfläche nicht zu dick ist, sondern vorher ab-, gebürstet wird, so daß nur ein dünner Film zurückbleibt.If you z. B. Gas container walls that dive into the sealing water with coated with an emulsion paint, and mineral oil is poured onto the sealing water, so becomes the emulsion paint if the container is unexpectedly immersed in the sealing water first coat themselves with the oil floating on it. The emulsion water remains then first in the paint until it is exposed to air when the gas container is removed gradually evaporated. Of course, such emulsions must also be used accordingly low water content. Prepared and so stable that it can be through wetting Do not suffer any damage with oil, but what is suspected with today's emulsion technology is possible. It is also possible to apply equivalent emulsions to surfaces, which were previously oiled, if you only make sure that the oil film on the coating surface is not too thick, but is brushed off beforehand, so that only a thin film remains behind.

Es ist nicht erforderlich, auf der Eisenfläche bereits vorhandene Ölübierzüge restlos zu entfernen; durch den dünmen Ölfilm zwischen Streichfläche und Emulsionsfarbenfilm wird Unterrostungen durch den Wassergehalt der Emulsion vorgebeugt.It is not necessary to already have it on the iron surface Remove all traces of oil; through the thin oil film between the brush surface and emulsion paint film will rust under due to the water content of the emulsion bent forward.
