Abstract

For the recycling and processing of polyolefin waste into micronised polyolefin wax, micronised polyolefin resin and micronised low mol. wt. polyolefin, the waste material mixture is degraded by heat and/or catalyst action and/or by oxidation degrading. The raw material is micronised by grinding or spraying.

Description

(1) Mikronisierung/Mikronisate: Polyolefinwachse, Polyolefinharze und niedermolekulare Polyolefine mit einer Korngrößenverteilung 100% < 100 µm. Sympatec, Helos Laser-Methode.(1) Micronization / micronisates: polyolefin waxes, polyolefin resins and low molecular weight polyolefins with a particle size distribution of 100% <100 µm. Sympatec, Helos laser method.

Mikronisierte(1) Polyolefinwachse, Polyolefinharze und niedermolekulare Polyolefine werden u. a. in der Druckfarben- und in der Lackindustrie eingesetzt.Micronized (1) Polyolefin waxes, polyolefin resins and low molecular weight polyolefins are used in the printing inks and coatings industries, among others.

Diese Mikronisate werden entweder durch Mahlung der entsprechenden Rohstoffe oder durch Kühlsprühung aus der Schmelze hergestellt.These micronisates are obtained either by grinding the appropriate raw materials or by cooling spray of the melt.

Die Rohstoffe für diese Mikronisate werden nach dem Hochdruckverfahren, dem Zieglerprozeß oder nach dem Fischer-Tropsch-Verfahren hergestellt. In allen Fällen werden als Ausgangsmaterialien immer die vom Erdöl abhängigen Monomere, wie z. B. Ethylen und Propylen eingesetzt.The raw materials for these micronisates are made after High pressure process, the Ziegler process or after Fischer-Tropsch process. In all cases are always made from petroleum dependent monomers, such as. B. ethylene and propylene used.

Polyolefinische Kunststoffabfälle können durch thermischen und/oder katalytischen Abbau zu Polyolefinwachsen, Polyolefinharzen, niedermolekularen Polyolefinen und durch oxydativen Abbau zu oxidierten Polyolefinwachse und -harze verarbeitet werden.Polyolefinic plastic waste can pass through thermal and / or catalytic degradation Polyolefin waxes, polyolefin resins, low molecular weight Polyolefins and oxidized by oxidative degradation Polyolefin waxes and resins are processed.

Diese aus polyolefinischen Kunststoffabfällen hergestellten Wachse und Harze können gemäß unserer Erfindung mikronisiert werden und z. B. in der Druckfarben- und Lackindustrie als Rohstoffe eingesetzt werden.This from polyolefin plastic waste Manufactured waxes and resins can according to our Invention are micronized and z. B. in the Printing ink and paint industry used as raw materials become.

Je nach Art, Zusammensetzung und Reinheit der eingesetzten Kunststoffabfälle entstehen unterschiedliche Qualitäten von mikronisierten Wachsen und Harzen.Depending on the type, composition and purity of the used plastic waste arise different qualities of micronized waxes and resins.

Der Verbrauch von reinen Monomeren (wie z. B. Ethylen, Propylen) für die Herstellung der Wachse und Harze kann durch unsere Erfindung reduziert werden. Die Umwelt wird weniger mit Kunststoffabfällen belastet.The consumption of pure monomers (such as ethylene, Propylene) for the production of waxes and resins can be reduced by our invention. The The environment is less polluted with plastic waste.
