Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Formartikeln und Flächenwaren aus einer Mischung, insbesondere einer Recyclingmischung, auf der Basis Gummimahlgut und Polyethylen.The invention relates to a process for the production of molded articles and flat goods from a mixture, in particular a recycling mixture, on the basis Rubber grist and polyethylene.
In der Patentschrift US-5 297 865 A wird ein Verfahren und eine Vorrichtung zur Herstellung einer Mischung beschrieben. Dabei wird zunächst in einem vorgeschalteten Maschinenteil der thermoplastische Werkstoff aufgeschmolzen.US Pat. No. 5,297,865 A describes a method and an apparatus for Preparation of a mixture described. First, it is in one upstream machine part of the thermoplastic material melted.
Anschließend erfolgt die Zuführung dieser Schmelze in einen Innenmischer, wo dann eine Vermischung mit anderen Komponenten stattfindet, beispielsweise mit Füllstoffen und/oder Gummimahlgut.This melt is then fed into an internal mixer, where then mixing with other components takes place, for example with fillers and / or ground rubber.
Die Aufgabe der Erfindung besteht nun darin, ein Verfahren bereitzustellen, das den thermoplastischen Werkstoff Polyethylen so mit einem Gummimahlgut vermischt, insbesondere unter dem Aspekt der Wiederverwertung von Rohstoffen, daß Formartikel und Flächenwaren herstellbar sind.The object of the invention is to provide a method that thermoplastic material polyethylene mixed with a rubber base, especially with regard to the recycling of raw materials that Molded articles and surface goods can be produced.
Die erfindungsgemäße Weiterentwicklung besteht nun darin, daß die Herstellung der
Polyethylen-Mahlgutmischung in folgenden Verfahrensschritten abläuft:
The further development according to the invention now consists in the production of the polyethylene regrind mixture taking place in the following process steps:
- - das Polyethylen wird in einem auf etwa 120°C vorgewärmten Mischungskneter (Innenmischer) aufgeschmolzen und geknetet;- The polyethylene is in a mixture kneader preheated to about 120 ° C. (Internal mixer) melted and kneaded;
- - nach ca. 3 Minuten Knetzeit wird das Mahlgut mit einer Korngröße von zweckmäßigerweise < 1,25 mm und gegebenenfalls die Zusatzstoffe (z. b. Ruß) dazugegeben, wobei der gesamte Knetvorgang ca. 5 bis 6 Minuten dauert; - After about 3 minutes of kneading time, the regrind with a grain size of expediently <1.25 mm and, if appropriate, the additives (e.g. carbon black) added, the entire kneading process taking about 5 to 6 minutes;
- - nach dem Auswurf aus dem Mischungskneter wird die Polyethylen-Mischung auf ein auf etwa 120°C vorgewärmtes Walzwerk gegeben und ca. 2 Minuten durchgearbeitet.- After ejection from the compound kneader, the polyethylene mixture is opened a rolling mill preheated to about 120 ° C and about 2 minutes worked through.
Als Gummimahlgut wird insbesondere EPDM oder ein Verschnitt aus NR/SBR
verwendet, u. z. in folgender Mischungszusammensetzung:
Gummimahlgut 50 bis 70 Gew.-%
Polyethylen 50 bis 30 Gew.-%EPDM or a blend of NR / SBR is used in particular as rubber ground material, in the following mixture composition:
Gum base 50 to 70% by weight
Polyethylene 50 to 30% by weight
Claims (4)
- - das Polyethylen wird in einem auf etwa 120°C vorgewärmten Mischungskneter (Innenmischer) aufgeschmolzen und geknetet;

- - nach dem Auswurf aus dem Mischungskneter wird die Polyethylen-Mischung auf ein auf etwa 120°C vorgewärmtes Walzwerk gegeben und ca. 2 Minuten durchgearbeitet.
- - The polyethylene is melted and kneaded in a mixture kneader (internal mixer) preheated to about 120 ° C;
- - After about 3 minutes of kneading time, the ground material and, if necessary, the additives (for example carbon black) are added, the entire kneading process taking about 5 to 6 minutes;
- - After ejection from the mixture kneader, the polyethylene mixture is placed on a rolling mill preheated to about 120 ° C. and worked through for about 2 minutes.
Gummimahlgut 50 bis 70 Gew.-%
Polyethylen 50 bis 30 Gew.-%4. The method according to any one of claims 1 to 3, characterized in that the following mixture composition is used:
Gum base 50 to 70% by weight
Polyethylene 50 to 30% by weight
