Description
Verfahren zur Stabilisierung von Kunstharzen Es ist bereits bekannt, Kunstharze durch 1'nisetzung von Aluminiumalkoholaten, ins besondere Aluminiumbutylat, oder von Alko- holaten anderer dreiwertiger Metalle mit Keto-Enol=Tautomerie aufweisenden Verbin dungen unter Verwendung von mindestens einem lfol der letzteren auf ein 31o1 3Ietall- alkoholat herzustellen.
Die nach diesem älteren Verfahren erhal tenen Produkte sind zähflüssige bis feste Kunstharze. Das bei der Herstellung der Kunstharze angewandte Molverhältnis beein- flusst vor allem die Lagerbeständigkeit. der leergestellten Produkte. In der Regel ist eine gute Lagerbeständigkeit nur dann vorhanden, wenn Metallalkohola,t und tautomer reagie rende Verbindung in einem Molverhältnis von liöelistens <B>1:1,5</B> miteinander umgesetzt wur den.
Die Lagerbeständigkeit ist dagegen ge ringer bei den Produkten, die einen geringe ren Anteil an der letzteren Verbindung ent halten, so dass sie mehr oder weniger schnell nach ihrer Herstellung weiter verarbeitet. wer den müssen. Die geringere Lagerbeständigkeit. äussert sieh in der Bildung einer Oberflächen haut sowie in Hydrolyseerscheinungen, unter Umständen schon beim Umgiessen der Harze, die zii einer mehr oder weniger starken Trü bung der Harze und zu einer Verschlechte- rung ihrer Trockeneigenschaften führen.
Für eine Weiterverarbeitung auf Lacke oder der gleichen, wobei im allgemeinen auf eine gute Trocknung Wert gelegt wird, sind jedoch gerade die Produkte interessant und auch aus wirtsehaftlichen Gründen erwünscht, deren Anteil an tautomer reagierender Verbindung gering ist.
Gegenstand dieses Patentes ist nun ein Verfahren zur Stabilisierung von Kunst harzen, das dadurch gekennzeichnet ist, dass durch Umsetzung von Alkoholaten dreiwerti ger Metalle mit Keto-Enol-Tautomerie auf weisenden Verbindungen hergestellte Kunst harze, vorzugsweise diejenigen, die durch Umsetzung von Alkoholaten dreiwertiger Me talle mit weniger als der 1,5fachen Molzahl von Keto-Fnol-Tautomerie aufweisenden Ver bindungen hergestellt wurden, durch Zusatz trocknender oder halbtrocknender Öle, wie Leinöl, .Sojaöl,
Ricinenöl oder dergleichen, sta bilisiert werden. ;So können beispielsweise die im Molverhältnis 1:1 hergestellten Kunst harze durch den Zusatz der genannten Öle in vollkommen stabile und unschädliche Produkte übergeführt werden, die eine verbesserte La gerbeständigkeit und damit auch Verarbeit- barkeit- besitzen.
Als Alkoholate kommen in erster Linie diejenigen des Aluminiums, jedoch auch solche des dreiwertigen Eisens oder anderer drei wertiger Metalle, in Frage, und als Keto- Enol-Tautomerie aufweisende Verbindungen bevorzugt Acetessigester oder andere Keto- säureester, ferner Malonsäureester und ss'-Keto- aldehyde, wie F'ormyla,ceton, ,Formylaceto- phenon oder dergleichen.
<I>Beispiel 1</I> Zn 950 Gewichtsteilen eines durch Um setzung von Al-Butylat mit Acetessigester im 1lolverhältnis 1 :1 erhaltenen Kunstharzes werden bei etwa. 50 bis 60 ' C 50 Gewichts teile rohes Leinöl gegeben. Durch den Öl- zusatz tritt eine deutliche Stabilisation ein, und das Produkt zeigt gegenüber dem ur sprünglichen Harz bei Lagerung, Umgiessen und ähnlichen Operationen keine Verände rungen.
<I>Beispiel 2</I> 900 Gewichtsteile des durch Umsetzung von Al-Butylat mit @lalonsäurediäthylester im Molverhältnis 1 :1 erhaltenen Kunstharzes werden in der Wärme mit 1!00 Gewichtsteilen Ricinenöl versetzt. Die Stabilisatorwirkung des Öls ist die gleiche, wie im Beispiel 1 be schrieben.
<I>Beispiel 3</I> 9 ? Gewiehtsteile des unter Beispiel 1 be schriebenen Kunstharzes aus Al-Butylat und Aeetessigester werden in der Wärme mit 8 Gewichtsteilen Sojaöl versetzt. Die stabili sierende Wirkung des Öls ist, die gleiche, wie in Beispiel 1 beschrieben.
<I>Beispiel- 4</I> Zu 950 G ewichtsteilen eines durch Um setzung, von Alunllnilunbutylat und Föi@nyl- aeetop'henon im 1@1olv erhältnis 1 :1 erhaltenen Kunstharzes werden bei etwa<B>5</B>0 bis 60 50 Gewichtsteile rohes Leinöl gefügt. Durch den Ölzusatz tritt eine deutliche Stabilisie rung ein, und das Produkt zeigt gegenüber dem ursprünglichen Harz bei Lagerung, Um giessen und ähnlichen Operationen keine Ver änderung mehr.
Process for stabilizing synthetic resins It is already known to use synthetic resins by adding aluminum alcoholates, in particular aluminum butylate, or alcoholates of other trivalent metals with keto-enol = tautomerism compounds using at least one lfol of the latter to a 31o1 3 Manufacture of metal alcoholate.
The products obtained by this older process are viscous to solid synthetic resins. The molar ratio used in the manufacture of the synthetic resins mainly influences the shelf life. of the empty products. As a rule, the shelf life is good only if the metal alcohols, and the tautomeric compound are reacted with one another in a molar ratio of a list of <B> 1: 1.5 </B>.
On the other hand, the shelf life is lower in the case of the products which contain a lower proportion of the latter compound, so that they are further processed more or less quickly after their manufacture. Need to become. The lower shelf life. This is expressed in the formation of a surface skin and in hydrolysis phenomena, possibly even when the resins are poured around them, which lead to a more or less severe clouding of the resins and to a deterioration in their drying properties.
For further processing on lacquers or the like, whereby value is generally placed on good drying, however, it is precisely those products whose proportion of tautomeric compound is low that are interesting and also desirable for economic reasons.
The subject of this patent is a method for stabilizing synthetic resins, which is characterized in that synthetic resins produced by reacting alcoholates trivalent metals with keto-enol tautomerism pointing to compounds, preferably those made by reacting alcoholates trivalent metals with less than 1.5 times the number of moles of keto-fnol-tautomerism compounds were produced by adding drying or semi-drying oils, such as linseed oil, soybean oil,
Ricin oil or the like can be stabilized. For example, synthetic resins produced in a molar ratio of 1: 1 can be converted into completely stable and harmless products with the addition of the oils mentioned, which have improved storage stability and thus also processability.
Alcoholates are primarily those of aluminum, but also those of trivalent iron or other trivalent metals, and compounds having keto-enol tautomerism are preferably acetoacetic esters or other keto esters, furthermore malonic esters and ss'-keto aldehydes, such as F'ormyla, cetone,, formylacetophenone or the like.
<I> Example 1 </I> Zn 950 parts by weight of a synthetic resin obtained by reacting Al-butylate with acetoacetic ester in a 1-molar ratio of 1: 1 are approx. 50 to 60 ° C given 50 parts by weight of raw linseed oil. The addition of oil results in a clear stabilization, and the product shows no changes compared to the original resin during storage, pouring and similar operations.
<I> Example 2 </I> 900 parts by weight of the synthetic resin obtained by reacting Al-butylate with lalonic acid diethyl ester in a molar ratio of 1: 1 are mixed with 100 parts by weight of ricin oil while heating. The stabilizing effect of the oil is the same as that described in Example 1.
<I> Example 3 </I> 9? Parts by weight of the synthetic resin described in Example 1 made of aluminum butylate and ethylacetate are mixed with 8 parts by weight of soybean oil when heated. The stabilizing effect of the oil is the same as that described in Example 1.
<I> Example- 4 </I> To 950 parts by weight of a synthetic resin obtained by reaction of aluminum nilunbutylate and foi @ nyl-aeetop'henon in a ratio of 1: 1 are about <B> 5 </B> 0 to 60 50 parts by weight of raw linseed oil are added. The addition of oil results in a clear stabilization, and the product no longer shows any changes compared to the original resin during storage, casting and similar operations.
