Description

Verfahren zur Herstellung rasch trocknender Lacke aus Teererzeugnissen. Die Herstellung rasch trocknender Lacke aus Cümaxonharzen ist, sofern diese nicht in dem schwer erzielbaren springharten Zustand verwandt werden, wegen ihres geringen Trock-. nungsvermôgens nicht môglich. Setzt man eine Lôsung von zâhem Cumaronharz in Solventnaphtha auf Blech Oder Glas in dünnen Schichten dër Luft aus; so trocknet sie überhaupt nicht vollig ein: Es hat sich nun gezeigt, daI3 man diesen Fehler beseitigen kann, wenn man das Cumaronharz mit den Substanzen vermischt, die aus der Rèinigungsschwefelsâure der Benzolkohlenwasserstoffe durch vorsichtige Zersetzung mit Wasser bei gleichzeitiger Anwesenheit von Benzol abgeschieden werden. Es sind dies in, trockenem Zustand leicht zerreibliche, gelbe Substanzen, die sich in Benzol und seinen Homologen mit rütlicher Farbe lôsen. Sie sollen in folgendem als Harztrockner bezeichnet werden. Am geeignetsten ist die direkt im Betrieb herstellbare Benzollôsung mit etwa 50 Prozent Trockensubstanz, die an der Luft in sehr kurzer Zeit zu einem harten Lack eintrocknet: Durch Mischen dieser Lüsung mit Cumaronharz 113t sich nun die Trockenzeit beliebig abstufen.Process for the production of quick-drying paints from tar products. The production of fast-drying lacquers from Cümaxonharzen is, provided they are not used in the hard-to-spring condition, which is difficult to achieve, because of their low drying properties. financial assets not possible. If one exposes a solution of tough coumarone resin in solvent naphtha on sheet metal or glass in thin layers of the air; it does not completely dry up at all: it has now been shown that this defect can be eliminated by mixing the coumarone resin with the substances which are separated from the cleaning sulfuric acid of the benzene hydrocarbons by careful decomposition with water in the presence of benzene. These are yellow substances that are easily friable when dry and that dissolve in benzene and its homologues with a reddish color. In the following, they will be referred to as resin dryers. The most suitable is the benzene solution with about 50 percent dry substance, which can be produced directly in the company and which dries in the air to a hard lacquer in a very short time: By mixing this solution with coumarone resin, the drying time can now be graded as desired.

Eine Mischung gleicher Teile Cumatonharz und Harztrocknerltisung trocknet in etwa 24 Stunden. Bei Anwendung von 2o Teilen Cumaronharz und 8o Teilen Harztrocknerlosung sinkt, besonders bei Gegenwart von Knrperfarbe, die Trockënzeit auf z bis 2 Stunden. Auf diesé Weise lassen sich also rasch trocknende besonders für Metall geeignete Lacke herstellen, die keine fetten O1e enthalten.A mixture of equal parts of Cumaton resin and resin dryer solution dries in about 24 hours. When using 2o parts coumarone resin and 8o parts resin drying solution The drying time is reduced to between 2 and 2 hours, especially in the presence of solid color. In this way, quick-drying, particularly suitable for metal, can be produced Produce paints that do not contain greasy oils.

Nur in wenigen Fâllen ist es zweckmüBig, dem Gemisch auch noch trocknendé fette Olé, wie mit Bleigliâtte verkochtes Leinül oder Holzôl, zuzusetzen, wodurch die Bindekraft erhüht wird.Only in a few cases is it advisable to add drying to the mixture To add fatty olé, such as linseed oil or wood oil cooked with lead slice, by which means the binding force is increased.
