Description

Verfahren zur Herstellung von trocknenden Lacken Gemäß der Erfindung werden hydrierte Naphthaline, z. B. Tetrahydronap!hthabn oder Dekahydronaphthalin, einem elektrischen Wechselfelde ausgesetzt. Die Folge dieser Einwirkung ist, daß zumindest einer der beiden Benzolringe i'n :den hydrierten Naphthalinen gesprengt wird und dabei ungesättigte Verbindungen entstehen, idie an der Luft trocknen und :daher als Lacke verwendet werden können. Zur Behandlung der hydrierten Naphthaline sind die zur Behandlung von Erdölen und fetten Ölen zum Zwecke der Viskositätserhöhung durch elektrische Wechselfelder bekannt gewordenen Vorrichtungen geeignet.Process for the preparation of drying paints according to the invention hydrogenated naphthalenes, e.g. B. Tetrahydronap! Hthabn or Dekahydronaphthalin, exposed to an alternating electric field. The consequence of this action is that at least one of the two benzene rings in the hydrogenated naphthalenes burst and unsaturated compounds are formed that dry in the air and : therefore can be used as varnishes. For the treatment of hydrogenated naphthalenes are those used to treat petroleum and fatty oils for the purpose of increasing viscosity suitable devices known from alternating electrical fields.

Das unter der Einwirkung des elektrischen Wechselfeldes entstehende Produkt ist mit dem Ausgangsprodukt vermengt. Man kann nun dieses Gemisch unmittelbar als Lack benutzen, da das noch beigemengte Ausgangsprodukt während des Trocknungsvorganges verdampft und der durch die Einwirkung des :elektrischen Wechselfeldes entstandene Stoff zurückbleibt. Um an dem teueren Ausgangsprodukt zu sparen, wird weiter erfindungsgem.ä.ß das Produkt der Behandlung durch Destillation von dem noch beigemengten Ausgangsprodukt getrennt. Um den so abgeschiedenen Stoff als Lack zu verwenden, kann er durch billige Lösungsmittel., z. B. Benzin, Benzol, verdünnt werden. Das Trocknen des Lackes geschieht bei normaler oder erhöhter Temperatur. Zur Bieschleuniwng des Vorganges wird zweckmäßig ozonisierte Luft zugeführt. Durch diese Behandlung wird die zur Trocknung notwendige Zeit unter Umständen bis auf ein Drittel herabgesetzt.That which arises under the influence of the alternating electric field Product is mixed with the starting product. You can now use this mixture directly Use as varnish, as the starting product still added during the drying process evaporated and the result of the action of the: alternating electric field Fabric remains. In order to save on the expensive starting product, according to the invention is also used the product of the treatment by distillation from the starting product still added separated. In order to use the material deposited in this way as a varnish, it can be bought cheaply Solvents, e.g. B. gasoline, benzene, can be diluted. The varnish is dried at normal or elevated temperature. To accelerate the process it is useful ozonated air supplied. This treatment makes the necessary for drying Time may be reduced to a third.

i. Betriebsbeispiel . Es wurden 70 ccm Dekahydronaphthalin bei einem Druck von 5 bis 7 mm Hg einer elektrischen Wechselstromentladung ausgesetzt. Die Spannung betrug 6ooo Volt, Frequenz 5oo Perioden/sek. Die oben angegebene Menge wurde 7 Stunden lang behandelt. Die Energieaufnahme des Apparates betrug während dieser Zeit 28o Wattstunden. Nach Abdestillieren des Ausgangsproduktes bei 12o° -und 8o mm Hg blieben 3q.,;6 °o Lacksubstanz zurück. z. Betriebsbeispiel 70 ccm Dekahydronaphthalin wurden bei 5 bis 7 @mm Hg Druck einer :elektrischen Wechselstromentladungausgesetzt. Spannung: 6ooo Volt, Frequenz: 5oo Perioiden/s.ek., Zeitdauer :der Behandlung: 31/2 Stunden. Die Energieaufnahme des Apparates betrug während :dieser Zeit 140 Wattstunden. Nach Abdestillieren des Ausgangsstoffes bei i2o° und einem Druck von 8o mm Hg blieben i 8, 51/2 Lacksubstanz zurück.i. Operational example. 70 cc of decahydronaphthalene was exposed to an alternating-current electrical discharge at a pressure of 5 to 7 mm Hg. The voltage was 600 volts, frequency 500 periods / sec. The above amount was treated for 7 hours. The energy consumption of the apparatus during this time was 280 watt hours. After the starting product had been distilled off at 120 ° and 80 mm Hg, 3%, 6 ° o lacquer substance remained. z. Operational Example 70 cc of decahydronaphthalene was subjected to an AC electrical discharge at 5 to 7 mm Hg pressure. Voltage: 600 volts, frequency: 500 perioids / s.ek., Duration: of the treatment: 31/2 hours. The energy consumption of the apparatus during this time was 140 watt hours. After the starting material had been distilled off at 130 ° and a pressure of 80 mm Hg, 1.51 / 2 of lacquer substance remained.
