Description

Es ist bekannt, flächenförmigen Gebilden aus thermoplastischen Kunststoffen, z. B. Platten, dadurch eine profilierte Oberfläche zu verleihen, daß die Innenseiten der Flachkammer, in der das Monomere.des Kunststoffes, z. B. Methacry1säuremethyiester, polymerisiert wird, entsprechend gestaltet sind. Auf diese Weise lassen sich Kunststoffe herstellen, die eine gerippte, mit erhabenen Ornamenten versehene oder eine ähnlich gestaltete Oberfläche besitzen.It is known that sheet-like structures made of thermoplastics, z. B. panels, thereby giving a profiled surface that the insides the flat chamber in which the Monomere.des plastic, z. B. Methacrylic acid methyl ester, is polymerized, are designed accordingly. In this way, plastics Produce a ribbed, embellished ornament or a similar one own designed surface.

Weiterhin ist bekannt, thermoplastische Kunststoffe einseitig zu trüben, indem man dem Monomeren solche Trübstoffe oder Pigmente zusetzt, die bei der horizontal gelagerten Kammer sedimentieren, d. h. sich im unteren Teil der Kunststoffplatte absetzen. Auf diese Weise lassen sich z. B. farbige Kunststoffplatten mit einer einseitig getrübten Oberfläche herstellen. Je spezifisch schwerer der Trübstoff ist und/oder je länger die Absetzdauer des Pigmentes im Monomeren währt, um so schärfer ist im Schnitt die Trennlinie zwischen (unterer) Pigmentschicht und (oberer) transparenter Schicht.It is also known to cloud thermoplastics on one side, by adding such turbid substances or pigments to the monomers as horizontal sediment in the stored chamber, d. H. located in the lower part of the plastic plate drop. In this way, z. B. colored plastic sheets with a Create a surface that is clouded on one side. The specific heavier the cloudiness and / or the longer the period of time for the pigment to settle in the monomer, the sharper the dividing line between the (lower) pigment layer and the (upper) layer is more transparent Layer.

Sowohl oberflächlich profilierte als auch einseitig pigmentierte Kunststoffe haben eine ausgedehnte gewerbliche Verwertung, vornehmlich in der Beleuchtungsindustrie, aber auch zum Verkleiden von Wänden und zu ähnlichen Zwecken, gefunden.Both surface profiled plastics and plastics pigmented on one side have extensive commercial exploitation, primarily in the lighting industry, but also for cladding walls and for similar purposes.

Bei Anwendung des nachstehenden erfindungsgemäßen Verfahrens lassen sich neue Effekte erzielen, die den Anwendungsbereich der danach hergestellten Kunststoffe verbreitern: Kombiniert man nämlich die genannte Methode der Oberflächengestaltung von Kunststoffen mit dem beschriebenen Verfahren der einseitigen Trübung, wählt jedoch die Pigmentart so aus und bemißt die anzuwendende Menge und/oder -die Absetzzeit derart, daß sich praktisch der gesamte Pigmentanteil in den Vertiefungen der formgebenden Flachkammerwand, d. h. in den erhabenen Teilen der so hergestellten Platte, absetzt, so erhält man oberflächlich profilierte bzw. mit Ornamenten versehene Kunststoffscheiben mit besonders plastischer Wirkung. Die erhabene Musterung hebt sich reliefartig vom Plattengrund ab und kontrastiert gleichzeitig, zumal in der Durchsicht, mit diesem farbmäßig und/oder der Lichtdurchlässigkeit nach in eindrucksvoller Weise. Das dem Monomeren zugesetzte Pigment hat sich, wie die Zeichnung erkennen läßt, bei horizontaler Lagerung der Kammern auf der Unterseite der Monomerenschicht derart abgesetzt, daß es sich praktisch vollständig in den Vertiefungen b der formgebenden Kammerwand ansammelt und sich beim fertigen Polymerisat ausschließlich in den erhabenen Teilen findet. Der Teil a der Platte ist glasklar oder transparent gefärbt.When using the following inventive method, leave achieve new effects that extend the scope of the plastics produced afterwards widening: If you combine the mentioned method of surface design of plastics with the described method of one-sided opacification however, determines the type of pigment and determines the amount and / or the settling time to be used in such a way that practically the entire pigment content is in the depressions of the shaping Flat chamber wall, d. H. in the raised parts of the plate produced in this way, in this way one obtains plastic disks which are profiled on the surface or provided with ornaments with a particularly plastic effect. The raised pattern is raised like a relief from the base of the plate and at the same time contrasts with it, especially when looking through it This is impressive in terms of color and / or transparency. The pigment added to the monomer has, as the drawing shows, with horizontal storage of the chambers on the underside of the monomer layer in this way discontinued that it is practically completely in the recesses b of the shaping Chamber wall accumulates and in the finished polymer is exclusively in the raised Share finds. Part a of the plate is colored clear or transparent.

Verformt man so hergestelltes Plattenmaterial thermoplastisch, d. h. durch Ziehen oder Drücken des bis zum Erweichungsintervall erwärmten Kunststoffes, so wird die geschilderte Wirkung durch harmonische Musterverdehnung noch verstärkt.If sheet material produced in this way is thermoplastically deformed, d. H. by pulling or pressing the plastic heated to the softening interval, the described effect is reinforced by the harmonious stretching of the pattern.

Die Anwendungsmöglichkeiten des erfindungsgemäßen Verfahrens sind mannigfaltiger Art: In farblosen, thermoplastischen Kunststoff läßt sich weißes oder farbiges Pigment einbringen, oder zu einem transparenten, d. h. mit einem löslichen Farbstoff gefärbten Monomeren läßt sich. gleichfarbiger oder farbig kontrastierender Trübstoff zusetzen usw. Die Dichte der Trübschicht kann durch Wahl des sich absetzenden Pigmentes und/oder durch eine entsprechende Bemessung' der Vertiefungen in der formgebenden Kammerwand, d. h. durch die Höhe der erhabenen Musterung, variiert werden. Die erzielte Verminderung der Lichtdurchlässigkeit kann zwischen einer schwachen Trübung und völliger Undurchsichtigkeit schwanken.The possible uses of the method according to the invention are Manifold kind: In colorless, thermoplastic plastic can be white or introduce colored pigment, or to a transparent, d. H. with a soluble Dye-colored monomers can. same color or color contrasting Add turbidity, etc. The density of the turbid layer can be determined by the choice of the sedimentation Pigment and / or by appropriate dimensioning 'of the depressions in the shaping Chamber wall, d. H. can be varied by the height of the raised pattern. The scored Reduction in light transmission can range between a weak haze and completely opaque.

Besonders eindrucksvolle Effekte lassen. sich bei Anwendung des erfindungsgemäßen Verfahrens erzielen, wenn als Trübstoff phosphoreszierende oder fluoreszierende Pigmente verwendet werden.Let particularly impressive effects. when using the invention Achieve method if phosphorescent or fluorescent as the cloudy substance Pigments are used.

Bei der Formgebung der Oberfläche ist man andie technischen Gegebenheiten im Bau der Formkammern gebunden. In jedem Fall, in dem die Oberfläche nicht plan ist, sondern Erhöhungen und Vertiefungen aufweist, läßt sich der plastische Eindruck durch Anwendung des erfindungsgemäßen Verfahrens in eindrucksvoller Weise verstärken.When it comes to shaping the surface, one is familiar with the technical conditions bound in the construction of the molding chambers. In any case where the surface is not flat is, but has elevations and depressions, the three-dimensional impression can be by applying the method according to the invention in an impressive manner.

Die Zeichnung- verdeutlicht den Erfindungsgedanken.The drawing illustrates the idea of the invention.
