Description

Verfahren zur Herstellung eines nicht entflammbaren Abbeizmittels Durch Quellen und Lösen von Kautschuk, z. B. des in der Kautschukmilch enthaltenen Kautschuks, in Chlorkohlenwasserstoff erhält man unbrennbare Anstrichentfernungsmittel. Diese besitzen gegenüber Nitrocelluloselackanstrichen eine bedeutend geringere Angriffs-und Lösefähigkeit als mit einem anderen Verdickungsmittel bereitete ester-, alkohol- und ketonhaltige Abbeizmittel. Es lag deshalb nahe, die beiden Lösungsmittelarten gleichzeitig zur Anwendung zu bringen. Das ist jedoch nur bei ganz verdünnten Kautschuklösungen möglich, da bei höherviskosen Lösungen der Kautschuk leicht ausgefällt wird, wodurch das Abbeizmittel die für eine gute Wirksamkeit erforderliche Konsistenz verliert.Process for the manufacture of a non-flammable paint remover By swelling and dissolving rubber, e.g. B. that contained in the rubber milk Rubber, in chlorinated hydrocarbons gives incombustible paint removers. Compared to nitrocellulose lacquer coatings, these have a significantly lower attack and resistance Solubility than ester-, alcohol- and ketone strippers. It was therefore obvious to use the two types of solvent to apply at the same time. However, this only applies to very dilute rubber solutions possible, since the rubber is easily precipitated in the case of higher-viscosity solutions, as a result of which the paint stripper loses the consistency required to be effective.

Es wurde nun festgestellt, daß man beide L ösungsmittelarten gleichzeitig verwenden und trotzdem Abbeizmittel von erwünschter Viskosität erhalten kann, wenn man folgendermaßen verfährt: Eine kleine Menge eines Emulgierungsmittels, z. B. sulfoniertes Öl, gibt man in Wasser und rührt diese Mischung in das kautschukfällende ester-, alkohol- oder ketonartige Lösungsmittel ein. Die entstandene wäßrige Lösung oder Emulsion fügt man zu einer wachs-, paraffin- oder ceresinhaltigen Lösung von Kautschuk in unbrennbarem Chlorkohlenwasserstoff und homogenisiert. Auf diese Weise erhält man Abbeizmittel von sahnebis salbenartiger Konsistenz und von vorzüglicher Wirksamkeit. Als kautschukfällende Lösungsmittel werden verwendet: einerseits Alkohole, Ester, Ketone und Gemische derselben, die mit Wasser mischbar oder mit diesem unter Zuhilfenahme eines Emulgators emulgierbar sind; andererseits Chlorkohlenwasserstoffe, wie Methylenchlorid, Dichloräthylen, Trichloräthylen, Tetrachlorkohlenstoff.It has now been found that both types of solvent can be used at the same time and still be able to obtain paint strippers of the desired viscosity, if the procedure is as follows: a small amount of an emulsifying agent, e.g. B. sulfonated oil, is added to water and this mixture is stirred into the rubber-precipitated oil ester, alcohol or ketone type solvents. The resulting aqueous solution or emulsion is added to a solution of wax, paraffin or ceresin Rubber in non-flammable chlorinated hydrocarbons and homogenized. In this way you get paint remover with a creamy to ointment-like consistency and excellent Effectiveness. The following solvents are used as rubber-precipitating solvents: on the one hand alcohols, Esters, ketones and mixtures thereof that are miscible with or with water Can be emulsified with the aid of an emulsifier; on the other hand chlorinated hydrocarbons, such as methylene chloride, dichloroethylene, trichlorethylene, carbon tetrachloride.
