Abstract
Description
Gegenstand der Erfindung sind transparente Polycarbonatformmassen für Kunst stoffartikel, die mindestens einen Thermostabilisator und ein Entformungshilfsmittel enthalten und die eine geringere Tendenz zur Staubanlagerung aufweisen.The invention relates to transparent polycarbonate molding compositions for art Fabric articles that have at least one thermal stabilizer and a mold release agent contain and have a lower tendency to accumulate dust.
Bei Kunststoffformkörpern ist die Anlagerung von Staub ein weit verbreitetes Problem. Siehe hierzu z. B. Saechtling, Kunststoff-Taschenbuch, 26. Ausgabe, Hanser Verlag, 1995, München, S. 140 f. Zum Beispiel lagert sich Staub bei der Lagerung unter technischen Bedingungen auf gespritzten Formkörpern ab. Besonders störend und die Funktion einschränkend sind Staubablagerungen bei transparenten Formkörpern. Ein wichtiger technischer Thermoplast ist Polycarbonat. Es wird in transparenten Einstellungen zum Beispiel für den Bereich optische Datenspeicher, Elektrotechnik, Automobilbau, im Bausektor, für Flüssigkeitsbehälter oder für andere optische Anwendungen verwendet. Für all diese Anwendungen von Poly carbonat ist eine Staubanlagerung unerwünscht und kann die Funktion beein trächtigen.In the case of molded plastic articles, the accumulation of dust is widespread Problem. See, for example. B. Saechtling, plastic paperback, 26th edition, Hanser Verlag, 1995, Munich, pp. 140 f. For example, dust accumulates with the Storage under technical conditions on molded articles. Especially disturbing and restricting the function are dust deposits in transparent Molded articles. An important technical thermoplastic is polycarbonate. It is in transparent settings, for example for the area of optical data storage, Electrical engineering, automotive engineering, in the construction sector, for liquid containers or for other optical applications used. For all of these applications from Poly carbonate is undesirable and can affect the function pregnant.
Eine bekannte Methode die Staubanlagerung auf Kunststoffkörpern zu vermindern ist durch den Einsatz von Antistatika. In der Literatur sind für Thermoplasten Anti statika beschrieben (siehe z. B. Gächter, Müller, Plastic Additives, Hanser Verlag, München, 1996, S. 749 ff), welche die Staubanlagerung einschränken. Diese Anti statika verbessern die elektrische Leitfähigkeit der Kunststoffformmassen und leiten so Oberflächenladungen, welche sich bei der Herstellung und beim Gebrauch bilden ab. Somit werden Staubpartikel nicht mehr vermehrt angezogen und folglich gibt es weniger Staubanlagerung.A known method is to reduce the accumulation of dust on plastic bodies through the use of antistatic agents. In the literature are anti for thermoplastics statika (see e.g. Gächter, Müller, Plastic Additives, Hanser Verlag, Munich, 1996, p. 749 ff), which limit the accumulation of dust. This anti statika improve the electrical conductivity of the plastic molding compounds and conduct thus surface charges that form during manufacture and use from. As a result, dust particles are no longer attracted and consequently there are less dust accumulation.
Man unterscheidet hierbei zwischen internen und externen Antistatika. Ein externes Antistatikum wird nach der Verarbeitung auf den Kunststoffformkörper aufgetragen, ein internes Antistatikum wird als Additiv bei der Verarbeitung zugesetzt. Aus wirtschaftlichen Gründen ist die Verwendung von internen Antistatika meist wünschenswert, da keine weiteren Arbeitsschritte zur Auftragung des Antistatikums nach der Verarbeitung nötig ist. Für transparente Einstellungen von Polycarbonat ist aber bis jetzt kein internes Antistatikum bekannt, welches die Staubanlagerung wirkungsvoll einschränkt und gleichzeitig die vorteilhaften Eigenschaften dieses Materials wie hohe Transparenz, niedrige Trübung und hohe Schlagzähigkeit nicht beeinträchtigt.A distinction is made between internal and external antistatic agents. An external one Antistatic is applied to the molded plastic body after processing, an internal antistatic is added as an additive during processing. Out The use of internal antistatic agents is mostly for economic reasons desirable since there are no further steps to apply the antistatic after processing is necessary. For transparent settings of polycarbonate but so far no internal antistatic known to dust accumulation effectively limits and at the same time the advantageous properties of this Materials like high transparency, low haze and high impact resistance are not impaired.
Ein Nachteil des Zusatzes von Antistatika ist darin zu sehen, daß sie wie jedes zugesetzte Additiv die Produktionskosten eines Gegenstandes erhöhen. Daher wäre es generell wünschenswert mit möglichst wenig Additiven (Anzahl und Menge) auszukommen.A disadvantage of adding antistatic agents is that they are like any other added additive increase the production cost of an item. Therefore would be it is generally desirable with as few additives as possible (number and quantity) get along.
Aus ästhetischen Gründen sind ferner die Muster der Staubfiguren von großer Bedeutung. Bei bisher üblichen Formmassen kommen oft störende bäumchenförmige Strukturen vor oder runde Strukturen mit Ausmaßen von 1-20 mm. Solche feinglie drigen Staubfiguren fallen stark ins Auge weil sie große Kontraste zwischen staubbe deckten und annähernd staubfreien Stellen zeigen. Wünschenswert wären Form massen, welche eher großflächige Staubfiguren an der Oberfläche ausbilden oder diese möglichst gleichmäßig bedecken.For aesthetic reasons, the patterns of the dust figures are also large Importance. In the case of molding compositions which have been customary to date, annoying tree-shaped ones often come Structures in front or round structures with dimensions of 1-20 mm. Such fine The other dust figures catch the eye because they have great contrasts between dust covered and show almost dust-free areas. Form would be desirable masses, which form rather large dust figures on the surface or cover them as evenly as possible.
Überraschenderweise wurden geeignete Additiv-Kombinationen gefunden, mittels denen sich die Staubanlagerung insgesamt stark einschränken läßt und mit welchen sich außerdem feingliedrige Staubfiguren weitgehend vermeiden lassen. Dabei kann auf den Zusatz von Antistatika verzichtet werden.Surprisingly, suitable additive combinations have been found by means of which the dust accumulation can be greatly restricted and with which you can also largely avoid delicate dust figures. It can the addition of antistatic agents can be dispensed with.
Die Aufgabe wurde erfindungsgemäß durch eine thermoplastische Formmasse gelöst,
welche als amorphes thermoplastisches Polymer Polycarbonat und mindestens einen
Thermostabilisator und ein Entformungshilfsmittel enthalten, wobei der

Aus diesem Granulat werden anschließend Rechteckplatten abgespritzt (155 mm × 75 mm × 2 mm).Unless otherwise stated, the test specimens were produced using an additive-free, unstabilized polycarbonate (Makrolon® 2808 from Bayer AG, Leverkusen) with an average molecular weight of approx. 30,000 ( MW according to GPC), solution viscosity: η = 1.293 at 340 ° C compounded on a twin-screw extruder with the specified amount of additive and then granulated. Rectangular plates are then injected from this granulate (155 mm × 75 mm × 2 mm).
Um die Staubanlagerung im Laborversuch untersuchen zu können, wurden die ge spritzten Platten einer Atmosphäre mit aufgewirbeltem Staub ausgesetzt. Es wurde ein 2-l-Becherglas mit einem 80 mm langen Magnetrührstab mit dreieckigem Querschnitt mit dem jeweiligem Staub ca. 1 cm hoch gefüllt. Mit Hilfe eines Magnetrührers wird der Staub aufgewirbelt. Nach dem Stoppen des Rührers wird der Probekörper 7 sec lang dieser Staubatmosphäre ausgesetzt. Je nach verwendetem Probekörper setzt sich mehr oder weniger Staub auf den Probekörpern ab. An schließend wird die Transmission und die Trübung nach der Vorschrift ASTM D 1003 mit dem Gerät Haze-Gard plus der Firma BYK-Gardner GmbH, D-82538 Geretsried bestimmt.

Es hat sich bewährt als Staub Kohlenstaub (hier 20 g Aktivkohle, Riedel-de Haen, Seelze, Deutschland, Artikel Nr. 18003) zu benutzen, weil hier die Wirkung und die Unterschiede deutlicher zu erkennen sind und einfacher zu messen sind als mit herkömmlichem Hausstaub.In order to be able to investigate the dust accumulation in the laboratory test, the ge splashed plates exposed to an atmosphere with whirled dust. It was a 2-liter beaker with an 80 mm long magnetic stirring bar with a triangular one Cross section filled with the respective dust about 1 cm high. With help of a The dust is whirled up with a magnetic stirrer. After stopping the stirrer, the Test specimens exposed to this dust atmosphere for 7 sec. Depending on the used Test specimen deposits more or less dust on the test specimen. On finally the transmission and the turbidity according to the regulation ASTM D 1003 with the Haze-Gard plus device from BYK-Gardner GmbH, D-82538 Geretsried determined. If the dust accumulation is uneven, the mean value will be determined determined several measurements. The transmission and the turbidity on 18 Places measured in the form of a 6 × 3 grid evenly on the rectangle plate are distributed. It has proven itself as dust coal dust (here 20 g activated carbon, Riedel-de Haen, Seelze, Germany, Article No. 18003), because here the Effect and the differences are more clearly recognizable and easier to measure are like with conventional house dust.
Ferner wird die Gewichtszunahme der Platte nach dem Bestäuben gemessen. Es wurde eine herkömmliche Laborwaage Mettler Toledo AE200 verwendet (Tabelle 3). The weight increase of the plate after dusting is also measured. It a conventional Mettler Toledo AE200 laboratory balance was used (Table 3).
