Abstract
Process for prodn. of moulded articles and sheet materials from a mixt. of (pref. recycled) milled rubber and polyethylene, in which the blend is prepd. by (a) melting and kneading the polyethylene in a mixer/kneader preheated to ca. 120 deg C, (b) after ca. 3 mins. kneading time, adding the milled rubber and any additives (e.g. carbon black) and continuing to a total kneading period of ca. 5-6 mins. and (c) after removal from the kneader, compounding the mixt. on hot rolls at ca. 120 deg C for ca. 2 mins.. Pref. the milled rubber is EPDM or NR/SBR and is milled to a particle size of less than 1.25 mu m. The compsn. comprises 50-70 wt.% milled rubber and 50-30 wt.% polyethylene.
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Form artikeln und Flächenwaren aus einer Mischung, insbesondere einer Recyclingmischung, auf der Basis Gummimahlgut und Poly ethylen, wobei hinsichtlich der Wiederverwertung von Gummi auf die Druckschriften (DE-A-37 19 291, EP-B-0 393 535) verwiesen wird.The invention relates to a method for producing mold articles and fabrics made from a mixture, in particular a recycling mixture, based on ground rubber and poly ethylene, with regard to the recycling of rubber to the documents (DE-A-37 19 291, EP-B-0 393 535) is referred.
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 that the production of the polyethylene regrind mixture in the following Process steps in progress:
- - das Polyethylen wird in einem auf etwa 120°C vorgewärmten Mischungskneter (Innenmischer) aufgeschmolzen und geknetet;- The polyethylene is preheated to about 120 ° C Mixing kneader (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 ground material is Grain size of suitably <1.25 mm and optionally the additives (e.g. carbon black) are added, the total Kneading takes about 5 to 6 minutes;
- - nach dem Auswurf aus dem Mischungskneter wird die Polyethylen- Mischung auf eine auf etwa 120°C vorgewärmte Walze gegeben und ca. 2 Minuten durchgearbeitet.- After ejection from the compound kneader, the polyethylene Mixture placed on a preheated roller to about 120 ° C. and worked through about 2 minutes.
Als Gummimahlgut wird insbesondere EPDM oder ein Verschnitt aus NR/SBR verwendet, u.z. in folgender Mischungszusammensetzung:EPDM or a blend is used in particular as rubber ground material used from NR / SBR, etc. in the following mixture composition:
Gummimahlgut 50 bis 70 Gew.-%
Polyethylen 50 bis 30 Gew.-%Gum base 50 to 70% by weight
Polyethylene 50 to 30% by weight
