Description

Verfahren zur Herstellung von harzartigen Kondensationsprodukten Das Patent 6 r o 5 56 betrifft die Herstellung von Kunstharzlacken auf Alkydharzbasis durch Umsetzung von mehrwertigen Alkoholen mit mehrbasischen Säuren bzw. deren Anhydriden in Gegenwart von Alkylcellulose, worauf das so erhaltene Harz mit Lacklösungsmitteln verdünnt wird. Dieses Verfahren ist nach Anspruch 2 dadurch gekennzeichnet, daß die mehrbasischen Säuren teilweise durch hochmolekulare einbasische Säuren ersetzt werden.Process for the preparation of resinous condensation products Das Patent 6 r o 5 56 relates to the production of synthetic resin paints based on alkyd resins by reacting polyhydric alcohols with polybasic acids or their anhydrides in the presence of alkyl cellulose, whereupon the resin thus obtained with varnish solvents is diluted. This method is characterized according to claim 2 in that the polybasic acids partially replaced by high molecular weight monobasic acids will.

In den britischen Patentschriften 320041 und 316325 hat man vorgeschlagen, Kombinationslacke unter Verwendung von Nitrocellulose oder Alkylcellulose dadurch herzustellen, daß man Nitrocellulos.e oder Alkylcellulose mit Alkydharzen in geeigneten Lösungsmitteln löst.In British patents 320041 and 316325 it has been proposed that Combination paints using nitrocellulose or alkyl cellulose thereby produce that one nitrocellulos.e or alkyl cellulose with alkyd resins in suitable Solvents dissolves.

Es wurde nun gefunden, daß man durch Kondensation eines fertigen, in an sich bekannter Weise aus Glycerin, Phthalsäure und höher molekularen Fettsäuren hergestellten Alkydharzes mit Celluloseäthern bei etwa 200° ein Harz erhält, das sich durch' Lösen in Benzolkohlenwasserstoffen oder anderen Lacklösungsmitteln zu Lacken verarbeiten läßt.It has now been found that by condensation of a finished, in a manner known per se from glycerol, phthalic acid and higher molecular fatty acids produced alkyd resin with cellulose ethers at about 200 ° a resin is obtained that by dissolving in benzene hydrocarbons or other paint solvents Can process paints.

Das beanspruchte Verfahren unterscheidet sich von den oben ,angeführten dadurch, daß es sich hier nicht um ein gewöhnliches Lösen oder Vermischen der Bestandteile handelt, da bei der Umsetzung die Hydroxylgruppen des Celluloseäthers mit dem fertigen modifizierten Alkydharz reagieren, was sich durch die dabei einsetzende Wasserabspaltung bemerkbar macht.The claimed method differs from the ones listed above in that there is no ordinary dissolving or mixing of the constituents here acts, since in the implementation the hydroxyl groups of the cellulose ether with the finished modified alkyd resin react, which results from the splitting off of water makes noticeable.

Lacke, die aus nach dem neuen Verfahren gewonnenen Produkten hergestellt sind, ergeben Überzüge, die sich von den aus anderen Kombinationslacken erhältlichen durch größere Helligkeit, Glanz und vor allem Wasserfestigkeit und Isolationsfähigkeit auszeichnen.Paints made from products obtained using the new process result in coatings that differ from those available from other combination paints through greater brightness, gloss and, above all, water resistance and insulation ability distinguish.

Beispiel r Zu 5o Teilen in bekannter Weise modifiziertem Alkydharz, bestehend aus 5o Teilen Phthalsäure-Glycerinharz und 5o Teilen Ölsäure, werden bei 200° 5 Teile Äthylcellulose zugegeben, worauf die Masse bei dieser Temperatur bis zum Aufhören der Wasserabspaltung homogenisiert wird.Example r Alkyd resin modified in a known manner to 50 parts, consisting of 50 parts of phthalic acid-glycerine resin and 50 parts of oleic acid are used in 200 ° 5 parts of ethyl cellulose added, whereupon the mass at this temperature up is homogenized to stop the elimination of water.

Beispiel 2 Zu 5oo Teilen in bekannter Weise modifiziertem Alkydharz, bestehend aus 5o Teilen Phthalsäure-Glycerinharz und 5o Teilen Ölsäure, werden bei etwa 22O° 5o Teile BenZ.ylcellulose zugegeben, worauf die -Masse bei dieser Temperatur bis zum Ende der Wasserabspaltung homogenisiert wird.Example 2 Alkyd resin modified in a known manner to 500 parts, consisting of 50 parts of phthalic acid-glycerine resin and 50 parts of oleic acid are used in about 220 ° 5o parts of benzyl cellulose were added, whereupon the mass was added at this temperature is homogenized until the elimination of water has ended.
