Abstract

Polyolefin waste is utilised by treatment by thermal, catalytic or oxidative decomposition to yield polyolefin waxes or polyolefin resins, or by oxidn. to yield oxidised polyolefins. USE/ADVANTAGE - The process allows polyolefin scrap to be utilised for prodn of useful prods such as polyolefin waxes, resins and oxidised polyolefins which are useful in the prodn of aq emulsion, polishes, floor polish, shoe polish, candles, adhesives, hot melt adhesives, coating compsns, asphalt compsns, paints, pigment concentrates, lubricants, printing inks, textile finishes, plastics processing assistants such as lubricants and release agents, etc. The process utilises waste material for mfr of useful prods, reduces the consumption of ethylene and propylene monomers, and reduces environmental pollution with discarded polyolefin waste.

Description

Die größten Mengen der angebotenen Polyolefin­ wachse und Polyolefinharze werden nach dem Hochdruckverfahren bzw. nach dem Zieglerprozeß hergestellt. Polymerisiert werden als Ausgangsmaterial immer die vom Erdöl abhängigen Monomere, wie z. B. Ethylen und Propylen.The largest quantities of polyolefin offered waxes and polyolefin resins are made after High pressure process or according to the Ziegler process produced. Be polymerized as The raw material always depends on the oil Monomers such as B. ethylene and propylene.

Einzelne Hersteller produzieren Polyolefin­ wachse und Polyolefinharze nach dem Abbauver­ fahren. Hier wird als Ausgangsmaterial Poly­ olefin thermisch, katalytisch bzw. oxidativ abgebaut. Für das hierfür verwendete Polyolefin werden ebenfalls die vom Erdöl stammenden Monomere (z. B. Ethylen und Propylen) ver­ braucht.Individual manufacturers produce polyolefin waxes and polyolefin resins after degradation drive. Here, poly olefin thermal, catalytic or oxidative reduced. For the polyolefin used for this will also come from petroleum Monomers (e.g. ethylene and propylene) ver needs.

Oxidierte Polyolefine, oxidierte Polyolefin­ wachse und oxidierte Polyolefinharze erhält man durch Oxidation des jeweiligen Ausgangsstoffes. Auch hier werden die reinen Monomere als ur­ sprünglicher Rohstoff verwendet.Oxidized polyolefins, oxidized polyolefins waxes and oxidized polyolefin resins are obtained by oxidation of the respective starting material. Here too, the pure monomers are considered original original raw material used.

Diese Produkte eignen sich z. B. zur Herstellung von wäßrigen Emulsionen, lösemittelhaltigen Polituren, Bohnermassen, Schuhcremes, Kerzen, Korrosionsschutzmittel, Beschichtungsmassen, Schmelzklebern, Asphaltzubereitungen, Kleb­ stoffen, Farbaufschlüssen, Lacken, Pigment­ konzentrationen, Kohlepapierbeschichtungen, Druckfarben, Textilausrüstungen, Vergußmassen, Schmierfetten, Schmiermittel und als Hilfs­ mittel für die Kunststoffverarbeitung (z. B. als Gleit- oder Trennmittel).These products are suitable for. B. for production of aqueous emulsions, solvent-based Polishes, floor masses, shoe creams, candles, Corrosion protection agents, coating compounds, Hot melt adhesives, asphalt preparations, glue substances, color digestions, varnishes, pigment concentrations, carbon paper coatings, Printing inks, textile equipment, casting compounds, Greases, lubricants and as an auxiliary agent for plastics processing (e.g. as Lubricants or release agents).

Gegenstand der Erfindung ist die Verwertung von Kunststoffabfällen (Polyolefinen) durch thermischen, oxidativen bzw. katalytischen Abbau zu Polyolefinwachsen, Polyolefinharzen bzw. durch Oxidation zu oxidierten Poly­ olefinen. Als Ausgangsmaterial werden vor­ sortierte, gereinigte oder sortenreine Kunst­ stoffabfälle eingesetzt. Neben den homopoly­ meren Kunststoffen wie z. B. Polyethylen und Polypropylen können auch copolymere Polyolefin­ abfälle eingesetzt werden. Als Produkt erhält man entsprechend Polyethylenwachse, Poly­ ethylenharze, Polypropylenwachse, Polypropylen­ harze, copolymere Olefinwachse oder copolymere Olefinharze.The object of the invention is the recycling of Plastic waste (polyolefins) thermal, oxidative or catalytic Degradation to polyolefin waxes, polyolefin resins or by oxidation to oxidized poly olefins. As a starting material will be sorted, cleaned or sorted art waste used. In addition to the homopoly meren plastics such. B. polyethylene and Polypropylene can also be copolymeric polyolefin waste is used. Received as a product one according to polyethylene waxes, poly ethylene resins, polypropylene waxes, polypropylene resins, copolymers of olefin waxes or copolymers Olefin resins.

Je nach Art und Reinheit der Kunststoffabfälle erhält man qualitativ unterschiedliche Wachse, Harze bzw. oxidierte Olefine. In nahezu allen Einsatzgebieten können die derzeit aus reinen Monomeren produzierten Produkte durch die aus Kunststoffabfällen hergestellten Produkte ersetzt werden.Depending on the type and purity of the plastic waste you get different quality waxes, Resins or oxidized olefins. In almost all of them Areas of application can currently be from pure Monomers produced by the products Products made of plastic waste be replaced.

Der thermische Abbau erfolgt in der Regel im Extruder. Der oxidative und katalytische Abbau bzw. die Oxidation des Polyolefins im Autoklaven. Das Know-How der einzelnen Ver­ fahren liegt bei nahezu allen Herstellern von Polyolefinen vor.Thermal degradation usually takes place in the Extruder. Oxidative and catalytic degradation or the oxidation of the polyolefin in Autoclaves. The know-how of the individual ver driving is with almost all manufacturers of Polyolefins.

Der heute große Verbrauch von reinen Monomeren (wie z. B. Ethylen, Propylen) für die Her­ stellung der Polyolefinwachse, Polyolefinharze bzw. oxidierten Polyolefinen kann durch die Erfindung reduziert werden. Die Umwelt wird weniger mit Kunststoffabfällen belastet.Today's high consumption of pure monomers (such as ethylene, propylene) for the Her position of the polyolefin waxes, polyolefin resins or oxidized polyolefins can by Invention can be reduced. The environment will less contaminated with plastic waste.
