Description
Oberflächeneinfärbung von Formkörpern aus acrylnitrilhaltigen Mischpolymerisaten Die für durchsichtige thermoplastische Kunststoffe bekannte Oberflächeneinfärbung läßt sich bei zum überwiegenden Teil aus Acrylnitril und zum restlichen Teil aus Methacrylsäuremethylester aufgebauten Kunststoffen dann nicht mit befriedigenden Ergebnissen durchführen, wenn großflächige Stücke gleichmäßig eingefärbt werden sollen. Bei den in Frage stehenden Mischpolymerisaten des Acrylnitrils handelt es sich um glasklare Kunststoffe, die sich durch besondere Festigkeit und Zähigkeit, vornehmlich bei Dauerbeanspruchung, auszeichnen.Surface coloring of moldings made from acrylonitrile-containing copolymers The surface coloring known for transparent thermoplastics can be predominantly made of acrylonitrile and the remainder Methacrylic acid methyl ester built up plastics then not with satisfactory Perform results when large pieces are colored evenly should. The acrylonitrile copolymers in question are are crystal-clear plastics, which are characterized by their special strength and toughness, primarily for continuous use.
Erfindungsgegenstand ist ein Verfahren zum Färben von Formkörpern aus Mischpolymerisaten von über 50 Gewichtsprozent Acrylnitril mit Methacrylsäuremethylester und gegebenenfalls untergeordneten Mengen weiterer Comonomerer durch Eintauchen in ein Färbebad aus einer Aceton-Wasser-Lösung eines organischen Farbstoffes und übliche Nachbehandlung, dadurch gekennzeichnet, daß man die Formkörper nach dem Färbebad in ein aus Wasser und 5 bis 30% Aceton bestehendes Egalisierungsbad einbringt und dann in üblicher Weise nachbehandelt.The subject of the invention is a method for coloring molded articles from copolymers of more than 50 percent by weight acrylonitrile with methacrylic acid methyl ester and, if appropriate, minor amounts of further comonomers by immersion in a dyebath of an acetone-water solution of an organic dye and Customary aftertreatment, characterized in that the shaped body after The dye bath is introduced into a leveling bath consisting of water and 5 to 30% acetone and then post-treated in the usual way.
Nach dem Egalisierungsbad werden die Formkörper in bekannter Weise mit Wasser abgespült, getrocknet und zur Beseitigung von Acetonresten auf 60 bis 70° C erwärmt. - Das erfindungsgemäße Verfahren kann durch die anspruchsgemäße Konzentration des Egalisierungsbades an Aceton durch die Behandlungsdauer des gefärbten Formkörpers in diesem Bad und/oder durch die Temperatur der Egalisierungsflotte in einfacher Weise auf die jeweils vorliegenden Bedürfnisse eingestellt werden.After the leveling bath, the moldings are made in a known manner Rinsed with water, dried and to remove acetone residues to 60 bis 70 ° C heated. - The method according to the invention can be achieved by the concentration according to the claims of the leveling bath of acetone due to the duration of treatment of the colored shaped body in this bath and / or by the temperature of the leveling liquor in simpler Way can be adjusted to the respective needs.
Nach dem erfindungsgemäßen Verfahren behandelte Platten sind vollständig gleichmäßig gefärbt und weisen auch bei intensiven tiefen Farbtönen nicht die störenden Farbschlieren auf, die ohne das dem Färbeprozeß angeschlossene Egalisierungsbad in der Regel auftreten. Die Platten sind hervorragend für die Verwendung als Farbeffekt- und Schutzscheiben vor der Bildröhre von Fernsehgeräten geeignet. Ausgedehnte Anwendung finden besonders die intensiv gefärbten Platten in der Werbetechnik und in besonderen Fällen der Beleuchtungstechnik. Für alle genannten Anwendungsgebiete ist eine vollkommen gleichmäßige Färbung zwingende Voraussetzung für die Verwendbarkeit des Plattenmaterials.Plates treated according to the method according to the invention are complete evenly colored and do not have the disturbing ones even with intense deep shades Color streaks appear without the leveling bath connected to the dyeing process usually occur. The panels are excellent for use as a color effect and protective screens in front of the picture tube of television sets. Extended use especially find the intensely colored panels in advertising technology and in special ones Cases of lighting technology. For all of the mentioned areas of application, one is perfect Uniform coloring is an essential prerequisite for the usability of the sheet material.
Formkörper der genannten Art zeigen den Nachteil der raschen elektrostatischen Aufladung und als deren Folge das starke Anziehen von Staub. Es ist bekannt, daß die Aufladung durch Behandeln des Formkörpers mit antistatischen Mitteln, z. B. auf Basis der alkalischen Salze von Fettalkoholsulfonaten, für längere Zeit verhindert werden kann. Es hat sich als vorteilhaft erwiesen, solche üblichen, die elektrostastische Aufladung verhindernden Stoffe dem Egalisierungsbad zuzusetzen.Moldings of the type mentioned show the disadvantage of rapid electrostatic Charging and, as a result, the strong attraction of dust. It is known that charging by treating the shaped body with antistatic agents, e.g. B. based on the alkaline salts of fatty alcohol sulfonates, prevented for a long time can be. It has been found to be advantageous to those usual, the electrostatic Adding charge-preventing substances to the leveling bath.
Mit Hilfe des beschriebenen Verfahrens gelingt es ferner auch in einfacher Weise, eine partielle bzw. streifenförmige Einfärbung von Plattenmaterial aus den genannten Mischpolymerisaten durchzuführen, und zwar derart, daß der Formkörper, z. B. eine Scheibe, zunächst bis zu einer gewissen Höhe in eine Färbeflotte eingebracht, danach mit Wasser gespült und in einem die erste Färbezone überdeckenden oder sich an diese Zone anschließenden Bereich in einer zweiten Flotte eingefärbt wird. Ein im Sinne der vorliegenden Erfindung nachgeschaltetes Egalisierungsbad läßt eine vollkommen gleichmäßige Einfärbung entstehen.With the aid of the method described, it is also possible in a simple manner Way, a partial or strip-shaped coloring of plate material from the to carry out said copolymers, in such a way that the shaped body, z. B. a disc, first introduced into a dye liquor up to a certain height, then rinsed with water and in a covering the first dyeing zone or each other the area adjoining this zone is colored in a second liquor. A in the sense of the present invention downstream leveling bath leaves a completely uniform coloring results.
