Description

Verfahren zur Herstellung von ofentrocknenden Lacken Nach dem Verfahren der Patentschrift 482 456 ist es bekannt, durch eine besondere Vorbehändlung fossile Harze in flüchtigen Stoffen, wie z. B. in Tetrachlörko-blenstoff und Alkohol, zu lösen. Es hat sich ergeben; daB diese Lösungen fossiler Harze, insbesondere deutschen Bernsteins, ,.auf Aluminium gestrichen, eine ganz besondere Haftfestigkeit der Anstrichfihne aufweisen.Process for the production of oven-drying paints According to the process the patent specification 482 456 it is known through a special pretreatment fossil Resins in volatile substances, such as B. in Tetrachlörko-blenstoff and alcohol, too to solve. It turned out; that these solutions of fossil resins, especially German ones Bernsteins,, .painted on aluminum, a very special adhesive strength of the paint vane exhibit.

Die Lösungen besitzen .meist eine Konzentration von i:io; bei. stärkerer Konzentration wird das genannte Verfahren ,aber insofern wenig rationell, als sich bildender Schleimabsatz einen Du hohen Prozentsatz der gesamten Lösung einnimmt.The solutions usually have a concentration of i: io; at. stronger Concentration is the process mentioned, but not very efficient as it is A high percentage of the total solution is taken up by the formation of slime.

Es wurde nun gefunden; daß eine wirtschaftliche Herstellung auch sehr hochprozentiger Lösungen fossiler Harze erzielt wird; wenn aus einer @öprazentigen Lösung durch Abtreibung der Lösungsmittel die gewünschte Konzentration herbeigeführt - wird. Man ist dadurch in der Lage; Lösungen von auf kaltem Wege aufgeschlossener fossiler Harze in beliebiger Konzentration zu erzielen., Dieses Verfahren - gewinnt eine besondere Bedeutung, wenn. man ,nicht bei dem Ziel von Lösungen fosiler Harze in flüchtigem Lösungsmitteln stehentleibt.It has now been found; that an economical production is also very good high percentage solutions of fossil resins is achieved; if from an @prazentigen Solution brought about the desired concentration by aborting the solvent - will. One is thereby able; Solutions from more open-minded on the cold path fossil resins in any concentration., This process - wins special meaning when. man, not aiming at solutions of fosil resins in volatile solvents.

Erfindungsgemäß können nun unter teilweiser Benutzung des Verfahrens der Patentschrift 482 q:56 nicht.. nur lufttrocknende, sondern .auch bei sehr hohen Temperaturen trocknende sog. Emaillelacke -aus fossilen Harzen hergestellt werden, wenn man nachder Konzentration der Bernsteinlösungen durch weitgehendeAbtreibung'der $üchtigenLösurngsmittel an deren Stelle Harzöle, wie Bernsteinöl, Kopalöl, setzt, die an sich fossile Harze, welche nach dem Verfahren der Patentschnit 48? 456 löslich gemacht worden sind, nicht lösen.According to the invention, partial use of the method can now the patent specification 482 q: 56 not .. only air-drying, but .also with very high Temperature-drying so-called enamel paints - made from fossil resins, if, after the concentration of the amber solutions, by extensive abortion of the Resin oils, such as amber oil, copal oil, replace them with volatile solvents, the fossil resins, which are produced according to the patent section 48? 456 soluble have been made do not solve.

Durch diese Substitution geeigneter Lösungsmittel, wie Tetrachlorkohlenstoff und Spiritus, durch .an sieh sonst ungeeignete, wie Harzöl, gelingt .es dann auch, i sehr erheblichen Mengen fette Öle, wie Rizinusöl, welche sonst ein Ausfällen der fossilen Harze zur Folge haben:-würden, den Harzlösungen einzuverleiben. Das Hetzöl spielt also die Rolle eines Lösungsvermittlers. -Die auf diese Weise herzestellten Lacl£e: und zeigen ganz vorzügliche elektrische Eigerischaften.This substitution of suitable solvents, such as carbon tetrachloride and spirit, by otherwise unsuitable ones, such as resin oil, then also enables very substantial amounts of fatty oils, such as castor oil, which would otherwise lead to the precipitation of the fossil resins to incorporate into the resin solutions. The agitation oil thus plays the role of a solubilizer. -The lacl £ e thus hearted: and show excellent electrical properties.

Beispiel i 6 kg i o prozentige Bernsteinlösung, hergestellt nach dem Verfahrender Patentschrift 482 456, in flüchtigen Lösungsmitteln werden durch Destillation von 4kg Lösungsmitteln zu .einer 3oprozentigen Bernsteinlösung konzentriert; 2 - Bernsteinlösung, 3oprozentig, 2 - Harzöl, 2 - Rizinusöl, i o ' g Bleimangansikkativ o. dgl.Example i 6 kg of 10 percent amber solution, prepared according to the process of patent specification 482 456, in volatile solvents are concentrated to a 3 percent amber solution by distilling 4 kg of solvents; 2 - amber solution, 3%, 2 - resin oil, 2 - castor oil, 10 g lead manganese siccative or the like.

Die Lacke können bei 175 bis 28o° je nach der Dauer der Hitzeeinwirkung üingebrannt werden. -Die vorliegende Erfindung hat gegenüber dem Verfahren der Patentschrift 482456 den Vorteil, daß durch die fast unbeschränkte Möglichkeit, der Bernsteinlösung fette öle einzuverleiben, eih bei hohen Temperaturen trocknender Einbrennlack hergestellt werden kann, der einen erheblich dickeren Film gibt, als dies nach dem Verfahren der Patentschrift, welches nur eine Herstellung von Lacken in flüchtigen Stoffen vorsieht, möglich ist. Solche aus fossilen Harzen hergestellten Lacke eignen, sich besonders zur Aerstellung von Lackisolierdrähten und zeigen als solche ne so hohe Isolierfähigkeit, daß auch ein Außer Bernstein kommen -zur Herstellung z. B. :auch fossile Kopale in Frage, und zwar wird vorzugsweise von der am meisten verwitterten Rinde, dem Grus, ausgegangen.The lacquers can be baked at 175 to 28o °, depending on the duration of the exposure to heat. The present invention has the advantage over the process of patent specification 482456 that, due to the almost unlimited possibility of incorporating fatty oils into the amber solution, baking varnish which dries at high temperatures can be produced which gives a considerably thicker film than is the case with the process of Patent specification, which only provides for the production of paints in volatile substances, is possible. Such varnishes made from fossil resins are particularly suitable for producing varnished insulating wires and, as such, show such a high insulating capacity that even a In addition to amber, z. B.: fossil copals are also in question, and preferably the most weathered bark, the grus, is assumed.

Beispiel 2 Man löst z kg Kongo-Kopal nach dem Verfahren der Patentschrift 482 456 und konzentriert diese Lösung; 2 - Harzöl, 2 - Rizinusöl, i o g Trockenstoff..EXAMPLE 2 Z kg of Congo copal are dissolved according to the method of the patent specification 482 456 and concentrate this solution; 2 - resin oil, 2 - castor oil, i o g dry matter ..
