Kunststoff zur Herstellung von Rohren, Platten, Scheiben und anderen Formkörpern durch Extrusion und SpritzgießenPlastic for the production of pipes, plates, discs and other shaped bodies by extrusion and injection molding

Die Erfindung "bezieht sich auf einen Kunststoff zur Herstellung von Rohren, Platten, Scheiben und anderen Formkörpern durch Extrusion und Spritzgießen, der durch Beimischung von Füllstoffen elektroantistatische Eigenschaften erhält.The invention "relates to a plastic for manufacture of pipes, plates, discs and other shaped bodies by extrusion and injection molding, which is achieved by adding fillers Preserves electro-antistatic properties.

Kunststoffe, z. B. Polystyrol, Polyamide, Polyäthylen - vornehmlich PVC, weich oder hart eingestellt - und andere sind gute Isolatoren, die jedoch den Nachteil haben, daß sich die daraus hergestellten Produkte elektrostatisch aufladen. Viele dieser Materialien scheiden deshalb für die Verwendung im chemischen Apparatebau aus.Plastics, e.g. B. polystyrene, polyamides, polyethylene - mainly PVC, soft or hard adjusted - and others are good insulators, but they have the disadvantage that they result from them electrostatically charge manufactured products. Lots of these Materials are therefore ruled out for use in chemical apparatus engineering.

Durch die DT-OS H 65 771 ist zwar bekannt, daß bereits Versuche zur Erhöhung der elektrischen Leitfähigkeit der Kunststoffe durchgeführt wurden., jedoch wird in diesem Falle nur eine Ladesehieht auf die Oberfläche aufgetragen. Als lösungsmittel wird hier beispielsweise Cyclohexanon verwendet.From DT-OS H 65 771 it is known that attempts have already been made to increase the electrical conductivity of plastics were carried out, but in this case only one loading view is shown applied to the surface. Cyclohexanone, for example, is used as a solvent.

Iß der DT-PS 920 125 wird ein Material beschrieben, das überwiegend aus Kohlenstoff besteht. Als Binder werden hier Aldehydharze verwendet;DT-PS 920 125 describes a material that predominantly consists of carbon. Aldehyde resins are used here as binders;

Gegenstand der Erfindung ist ein Kunststoff zur Herstellung von Bohren, Platten, Scheiben und anderen Formkörpern durch Extrusion und Spritzgießen, der durch Beimischung von Füllstoffen aus elektrisch leitenden Kohlenstoffmaterialien elektroantistatische Eigenschaften erhält.The invention relates to a plastic for the production of bores, plates, discs and other shaped bodies by extrusion and injection molding, which is given electro-antistatic properties by adding fillers made of electrically conductive carbon materials.

Ale-füllstoffβ kommen vorzugsweise Kunst- oder, Naturgraphite oder amorphe Kohlematerialien oder Gemische dieser Materialien in Betracht. Ale fillers are preferably synthetic or natural graphite or amorphous carbon materials or mixtures of these materials.

Die Menge dieser Füllstoffe, bezogen auf die Kunststoffgrundmischung, beträgt zwischen 5 und 60 $>. Kunst- und Füllstoffe werden zusammen in Mischern oder Knetern zu einer einheitlichen preß- oder spritzfähigen Masse gemischt. Nach dem Pressen bilden sie homogene Körper, die sich nicht mehr elektrostatisch aufladen.The amount of these fillers, based on the plastic base mixture, is between $ 5 and $ 60. Plastics and fillers are mixed together in mixers or kneaders to form a uniform mass that can be pressed or injected. After pressing, they form homogeneous bodies that no longer become electrostatically charged.

Durch die Verwendung von Kohlenstoffmaterialien als Füllstoffe ergeben sich Festigkeitswerte, wie sie bisher noch durch kein Füllmaterial erreicht wurden.The use of carbon materials as fillers results in strength values that have never been achieved before Filler material have been reached.
