Description

Verfahren zur Herstellung von Lacken und Anstrichmitteln Die in dem Patent 570 q:86 beschriebenen Harzlösungen entstehen durch die Kondensations- bzw. Polymerisationswirkung der Schwefelsäure. Eine ähnliche bzw. eine steigernde Wirkung entsteht durch Verwendung anderer Kondensations- bzw. Polymerisationsbeschleuniger, z. B. durch wasserfreies Aluminiumchlorid.Process for the production of lacquers and paints The resin solutions described in patent 570 q: 86 arise from the condensation or polymerisation effect of sulfuric acid. A similar or an increasing effect is created by using other condensation or polymerization accelerators, e.g. B. by anhydrous aluminum chloride.

Die Harze, die bei Verwendung von wasserfreiem Aluminiumchlorid entstehen, sind zwar dem Kumaronharz verwandt, aber nicht ganz gleich. Ebenso entstehen bei anderen Polymerisationsbeschleunigern ähnliche, den Harzgehalt der Lösung steigernde andere Harze, die keine Kumaron-, - sondern verwandte Harze sind. Alle haben gegenüber abdestillierten und nachher wieder gelösten Harzen den Vorzug, daß sie, weil auf kaltem Wege entstanden, wenig Wärmeeinwirkung ausgesetzt waren und däß sie dadurch weichere und geschmeidigere Filme ergeben als die durch Abdestillieren der Lösungsmittel gewonnenen Harze.The resins that are formed when using anhydrous aluminum chloride, are related to the coumarone resin, but not exactly the same. Likewise arise with similar to other polymerization accelerators, increasing the resin content of the solution other resins other than coumarone resins but related resins. All have opposite distilled off and then redissolved resins have the advantage that they, because on cold path, were exposed to little heat and that they were thereby softer and more pliable films result than those obtained by distilling off the solvents recovered resins.

Beispiel I In einer Waschflasche, wie unter Beispiel I des Hauptpatents beschrieben, läßt man durch eine Schicht von io cm Höhe wasserfreien Aluminiumchlorids auf den Boden dieser Schicht Solventnaphtha in fein verteilten Strahlen unter mäßigem Druck bei gewöhnlicher Temperatur einlaufen, so daß die Solventnaphtha in kleinen Tropfen durch das wasserfreie Aluminiumchlorid hindurchperlt. Dabei bildet sich eine etwa 12 °1o Harz enthaltende Harzlösung, die oben aus der Flasche abfließt -und als Anstrichinittel verwendet wird.Example I In a washing bottle, as in Example I of the main patent described, is passed through a layer 10 cm high anhydrous aluminum chloride on the bottom of this layer of solvent naphtha in finely divided jets under moderate Shrink pressure at ordinary temperature, so that the solvent naphtha in small Drops bubbled through the anhydrous aluminum chloride. This forms a resin solution containing about 12 ° 1o resin that drains from the top of the bottle -and is used as a paint.

Beispiel II Nach Beispiel I1 des Hauptpatents behandelte Solventnaphtha, die eine etwa io°loige Kumaronharzlösung ergeben hat, wird in der beschriebenen Waschvorrichtung durch eine io cm hohe Schicht von wasserfreiem Aluminiumchlorid hindurchgedrückt, wodurch zusätzliche Harzbildung stattfindet, so daß die io °1a Kumaronharz sich auf etwa 15 °/o Harzgehalt, bestehend aus Kumaron- und ähnlichen Harzen, erhöht. Diese Harzlösungwird in der im Hauptpatent beschriebenen Weise weiterverarbeitet. BeispielIII 1n einer Waschflasche, wie unter Beispiel I beschrieben, läßt man durch eine Schicht von 15 cm Höhe wasserfreien Eisenchlorids auf den Boden dieser Schicht Solventnaphtha in fein verteilten Strahlen unter mäßigem Druck bei gewöhnlicher Temperatur einlaufen, so daß die Solventnaphtha in kleinen Tropfen durch das wassefr`eie Eisenchlorid hindurchperlt. Dabei- bildet si.eine etwa 25 °/o Harz enthaltende .gaizlösürig-: die oben aus der Flasche abfließt und*=eis Anstrichmittel verwendet Wixd>`_ -,:qf -=,Example II Solvent naphtha treated according to Example I1 of the main patent, which has resulted in an approximately 100% coumarone resin solution, is pressed through a 100 cm high layer of anhydrous aluminum chloride in the washing device described, whereby additional resin formation takes place, so that the 100% coumarone resin is deposited about 1 5 ° / o resin content consisting of Kumaron- and similar resins increases. This resin solution is processed further in the manner described in the main patent. Example III In a wash bottle, as described under Example I, solvent naphtha is allowed to run in finely divided jets under moderate pressure at ordinary temperature through a layer of anhydrous iron chloride 1 5 cm high on the bottom of this layer, so that the solvent naphtha in small drops through the water-free ferric chloride bubbles through. In doing so, it forms a .gaizlösürig- containing about 25 % resin: which flows out of the top of the bottle and uses paint Wixd> `_ - ,: qf - =,

PATENTANSPRUCH: Weitere Ausbildung des in dem Patent 570 486 geschütztenVerfahrens, dadurch gekennzeichnet, daß man an Stelle der in dem Hauptpatent beschriebenen Harzlösungen die durch Behandlung mit anderen bekannten Kondensations- und Polymerisationsbeschleunigern, z. B. Aluminiumchlorid, hergestellten Harzlösungen verwendet. Claim: Further development of the process protected in patent 570 486, characterized in that, instead of the resin solutions described in the main patent, the resin solutions obtained by treatment with other known condensation and polymerization accelerators, e.g. B. aluminum chloride, prepared resin solutions are used.
