Description

Verfahren zur Herstellung von Überzügen aus Emulsionen Bisher wurde das Aufbringen eines in Wasser emulgierten Lackes auf Gegenstände des all- gemeinen Gebrauches dadurch bewerkstelligt, daß der zu behandelnde Gegenstand in den etnulg ierteü Lack eingetaucht wurde oder daß die eniulgierten Lackteile elektrisch nieder- geschlagen wurden. Diese Verfahren waren not- wendig, da die gewöhnliche Art des Rufstrei- chens mit dem Pinsel bei in Wasser emulgiertem Lack infolge seiner Dünnflüssigkeit nicht durch- führbar ist. ES ist bekannt, in Wasser emulgierte Öl- und Harzverbindungen, beispielsweise Lacke, mittels eines Elektrolyten auszufällen; nicht bekannt war es jedoch, diesen mittels eines Elektrolyten ausgefällten Lack auf Gegenstände in Gegen- wart des Elektrolyten niederzuschlagen. Er- findtnigsgemäß wird ein besonders fest haftende- L"berzuin (-itifaclier Weise dadurch her@c.-t@#llt, daß die Oberflache des zll behandelnden (;,#gen- Standes zuerst mit ollem Elektrolyten über- zogen, darauf die, wasserlge Lackeln111sion auf- getragen und diese durch den Elektrolyten auf dur Oberfläche des Gegenstande; nieder- geschlagon wird. llan kann z. K den (legE,ti- stand in (#111e wässerige Lösung von Alkali- salzen, wie Natrium- oder haliumhy(iro@yd. tauchen, wobei eine il - bis 2prozentig( Lö- sung ausreichend ist. 1)er Gegenstand wird nun getrockhet und das Alkali bleibt als dünner tberzug auf ihm zurück. Sodann taucht man ihn in die Lackemulsion, welche sich auf dem Alkaliüberzug niederschlägt und die Oberfläche des Gegenstandes mit einem fest anhaftenden t berzug bedeckt. Man kann auch andere als die obenerwähnten Elektrolyte, z. B. Natriumchlorid, verwenden, doch ist dem Alkali der Vorzug zu geben.Process for the production of coatings from emulsions So far it has been applying one in water emulsified paint on objects of the general common use brought about by that the object to be treated in the some paint has been immersed or that the eniulsified paint parts are electrically were beaten. These procedures were necessary manoeuvrable, since the usual type of call chens with the brush when emulsified in water Due to its thinness, the paint does not penetrate is feasible. It is known to be oil and emulsified in water Resin compounds, such as paints, means precipitate an electrolyte; not known it was, however, using an electrolyte precipitated paint on objects in opposition waiting for the electrolyte to precipitate.

It is then dipped into the lacquer emulsion, which is deposited on the alkali coating and covers the surface of the object with a firmly adhering coating. It is also possible to use electrolytes other than those mentioned above, e.g. B. sodium chloride, but the alkali is to be given preference.

Die hauptsächlichsten Vorteile des Verfahrens sind Billigkeit. und seine weitgehende Anwendungsmöglichkit.The main advantages of the process are cheapness. and its extensive application possibilities.
