Description
Nicht quellbare plastische lassen Es ist bekannt, Alkylcellulose, die in Wasser unterhalb -f-16° C löslich ist, wit wasserunlöslichen Cellulosederivaten zu vereinigen.Non-swellable plastic leave It is known that alkyl cellulose, which is soluble in water below -f-16 ° C, with water-insoluble cellulose derivatives to unite.
Es wurde nun gefunden, daß man Methylcellulose, die über -+--16° C wasserlöslich ist, mit Äthyl-, Acetyl- oder Nitrocellulose vermischen kann. Man erhält plastische Massen, wie beispielsweise Filme, Kunstfäden, Lacke u. dgl., die nicht quellbar sind. Es war nicht vorauszusehen, daß Methylcellulose, die bei wesentlich höherer Temperatur wasserlöslich ist, sich mit wasserunlöslichen Cellulosederivaten vermischen läßt, und vor allem, daß dieses Gemisch seine Wasserlöslichkeit völlig verliert.It has now been found that methyl cellulose which is above - + - 16 ° C is water soluble, can mix with ethyl, acetyl or nitrocellulose. Man receives plastic materials, such as films, synthetic threads, lacquers and the like are not swellable. It was not foreseeable that methyl cellulose, which was essential higher temperature is water-soluble, deal with water-insoluble cellulose derivatives can be mixed, and above all that this mixture is completely water-soluble loses.
Beispiele 1. 7 5 Gewichtsteile Methylcellulose werden mit so viel Alkohol versetzt, daß gerade völlige Gelatinierung eintritt, und mit 25 Gewichtsteilen einer mit Aceton gelatinierten Acetylcellulose gut vermischt, worauf die Lösungsmittel verdunstet werden. Es entsteht ein zur Verwendung für plastische Massen aller Art geeignetes, mit Wasser nicht mehr quellbares Produkt.Examples 1. 7 5 parts by weight of methyl cellulose are used with so much Alcohol is added so that complete gelatinization occurs, and with 25 parts by weight an acetyl cellulose gelatinized with acetone, whereupon the solvents to be evaporated. The result is a for use for plastic masses of all kinds suitable product that can no longer swell with water.
2. Die 1 o %ige wäßrige Lösung einer wasserlöslichen Methylcellülose ist imstande, bis etwa 2% des Gewichts der angewandten Methylcellulose an wasserunlöslicher Äthylcellulose zu lösen. Aus dieser Lösung hergestellte plastische Massen, z. B. ein gegossener Filmstreifen, zeigt nach dem Eintrocknen eine erheblich höhere Widerstandsfähigkeit gegen Wasser als das Ausgangsmaterial.2. The 10% aqueous solution of a water-soluble methyl cellulose is capable of up to about 2% of the weight of the methyl cellulose used in water-insoluble To dissolve ethyl cellulose. Plastic masses produced from this solution, e.g. B. a cast film strip shows a considerably higher resistance after drying against water as the starting material.
Man kann auch beispielsweise 5o Gewichtsteile Methylcellulose reit 5o Gewichtsteilen Wasser in einer Knetmaschine verarbeiten, bis eine homogene Masse entstanden ist, darauf 5o Gewichtsteile einer mit Sprit durchgequollenen Äthylcellulose hinzusetzen und so lange verarbeiten, bis wieder Homogenität` eingetreten ist. Hierauf entfernt man die Lösungsmittel durch Evakuieren. Um eine besondere Geschmeidigkeit oder Plastizität zu erreichen, kann man der Mischung die bekannten Weichmachungs- oder Kampferersatzmittel zusetzen.It is also possible, for example, to ride 50 parts by weight of methyl cellulose Process 5o parts by weight of water in a kneading machine until a homogeneous mass has arisen, then 50 parts by weight of an ethyl cellulose swollen with fuel add and process until homogeneity has returned. On that the solvents are removed by evacuation. For a special suppleness to achieve plasticity, the mixture can be mixed with the known plasticizing or add camphor substitutes.
3. 25 Gewichtsteile Methylcellulose werden mit etwa 2o Gewichtsteilen Wasser zu einer homogenen Paste vermischt und diese Paste mit 5o Gewichtsteilen einer mit Äthylacetat oder mit einer Mischung von Äthylacetat, Aceton und Butylacetat angequollenen Nitrocellulose verarbeitet. Der Mischung bzw. der Nitrocellulosequellungkönnen Kampfer oder dessen Ersatzmittel zugesetzt werden.3. 25 parts by weight of methyl cellulose are mixed with about 20 parts by weight Water mixed to a homogeneous paste and this paste with 5o parts by weight one with ethyl acetate or with a mixture of ethyl acetate, acetone and butyl acetate processed swollen nitrocellulose. The mixture or the nitrocellulose swelling can Camphor or its substitute are added.
