Description

Verfahren zur Herstellung von Lacken, Imprägnierungsmitteln u. dgl. Es ist bekannt, daß Acetylcellulose in wasserfreiem sowie kleine Wassermengen enthaltendem Äthylenchlorhydrin löslich ist. Hingegen lösen sich die handelsüblichen Acetylcellttlosen mit einem Essigsäuregehalt von über 50 Prozent nicht in stark wasserhaltigem Äthylenchlorhydrin.Process for the production of lacquers, impregnating agents and the like. It is known that acetyl cellulose is soluble in anhydrous ethylene chlorohydrin which contains small amounts of water. On the other hand, the commercially available acetyl cellulose with an acetic acid content of more than 50 percent do not dissolve in the highly hydrous ethylene chlorohydrin.

Es wurde nun die überraschende Beobachtung gemacht, daß sich Acetylcellulose mit einem Gehalt von weniger als 50 Prozent Essigsäure außerordentlich leicht in stark wasserhaltigem Äthylenchlorhy drin zu .technisch wertvollen Lacken, Filmlösungen, Imprägnierungs- und Druckereilösungen u. dgl. löst. Selbst ein Lösungsgemisch von do Prozent Äthylenchlorhydrin und 6o Prozent Wasser ergibt noch einwandfreie Lösungen, die klar auftrocknen, während höher acetylierte Cellulose in diesem Gemisch praktisch unlöslich ist. Man kann selbst Lösungsgemische von 30 Prozent Äthylench:lorhydrin und 70 Prozent Wasser benutzen, wenn man diesem Gemisch etwas Aceton oder Alkohol zusetzt.The surprising observation has now been made that acetyl cellulose with a content of less than 50 percent acetic acid dissolves extremely easily in highly hydrous ethylene chlorine to produce technically valuable paints, film solutions, impregnation and printing solutions and the like. Even a solution mixture of do percent ethylene chlorohydrin and 60 percent water results in perfect solutions that dry up to be clear, while more highly acetylated cellulose is practically insoluble in this mixture. You can even use a mixture of 30 percent ethylene: lorhydrin and 70 percent water if you add a little acetone or alcohol to this mixture.

Der Vorteil der' Wasser-Äthylenchlorhydrin-Gemische als Lösungsmittel für niedrig acetylierte Cellulose gegenüber den bekannten Lösungsmitteln, wie Aceton, Alkohol-Essigester-Gemischen, liegt in der großen Billigkeit und der völligen Unbrennharkeit derLösungen, so daß derartige Lacke keinen Beschränkungen hinsichtlich Feuergefährlichkeit, Versand, Lagerung und Verarbeitungsweise unterliegen. Man kann diese Lösungen auch mit geeigneten Farbstoffen versetzen und durch Weichmachungsmittel oder Harze in ihren Eigenschaften beeinflussen. Beispiel I.The advantage of the 'water-ethylene chlorohydrin mixtures as a solvent for low acetylated cellulose compared to known solvents such as acetone, Alcohol-ethyl acetate mixtures are cheap and completely non-combustible of the solutions, so that such paints do not have any restrictions on the risk of fire, Shipping, storage and processing methods are subject. You can do these solutions too add suitable dyes and softening agents or resins in affect their properties. Example I.

ro Gewichtsteile Acethylcellulose mit einem Gehalt von 47 Prozent Essigsäure werden in einem Gemisch von q.o Gewichtsteilen Äthvlenchlorhydrin und 5o Gewichtsteilen Wasser gelöst.ro parts by weight of acetyl cellulose with a content of 47 percent Acetic acid are in a mixture of q.o parts by weight of Äthvlenchlorhydrin and 5o parts by weight of water dissolved.

Beispiel II.Example II.

8 Gewichtsteile einer Acetylcellulose mit _l3 Prozent Essigsäuregehalt «-erden in 4.9 Gewichtsteilen Äthylenchlorhy drin und 4 3 Gewichtsteilen Wasser unter Zusatz von a Gewichtsteilen p-Toluolsulfosäureäthylamid gelöst. Diese Lösung kann vorteilhaft für Imprägnierungszwecke verwendet werden.8 parts by weight of an acetyl cellulose with _13 percent acetic acid content «-Erden in 4.9 parts by weight of Äthylenchlorhy and 4 3 parts by weight of water dissolved with the addition of a parts by weight of p-toluenesulfonic acid ethylamide. This solution can advantageously be used for impregnation purposes.
