Description

  

  Mischung zur Herstellung von Unterböden für Fussbodenbeläge und Verfahren  zur Herstellung einer solchen Mischung    Die Erfindung bezieht sich auf eine Mi  schung für die Herstellung von Unterböden  für Fussbodenbeläge. Es ist üblich, dass man  einen solchen Unterboden (auch Estrich ge  nannt) in einer Dicke von 15 bis 30 mm auf  einer Rohdecke verlegt und auf ihn eine Geh  schicht in einer Dicke von etwa 5 mm oder  eine     Deckschicht    von etwa 4 mm Dicke     und     dann einen Belag aus Linoleum, Folien aus       Polyvinylchlorid    oder einem andern Kunst  stoff, Gummibahnen oder Parkett aufbringt.  



  Bisher wurde dieser Estrich in der Haupt  sache als     Steinholzestrich        ausgeführt,    das  heisst aus einer Mischung von gebranntem       Magnesit    und     Chlormagnesiumlauge    sowie  Füllstoffen, wie Sägespänen, Sägemehl, Bims,  zum Teil mit Korkzusatz usw. Auch hat man  als Füllstoffe schon Faserstoffe, wie Baum  wolle, Wolle, vorgeschlagen.  



  Demgegenüber ist die erfindungsgemässe  Mischung dadurch gekennzeichnet, dass sie  ausser einem Bindemittel als Füllstoffe  Gummifasern und körnige Gummiteilchen  aufweist.  



  Das erfindungsgemässe Verfahren zur Her  stellung einer solchen Mischung ist dadurch  gekennzeichnet, dass man die genannten Füll  stoffe durch mechanische Zerkleinerung von       Altgummimaterial    gewinnt.  



  Die mechanische Zerkleinerung kann zum  Beispiel durch Zerreissen, Zerschneiden,  Mahlen oder Abreiben erfolgen.    Als Bindemittel     können    zum Beispiel ver  wendet werden: gebrannter     Magnesit    mit       Chlormagnesiumlauge,        Polyvinylazetat    oder       Polyvinylchlorid.

  Mixture for producing sub-floors for floor coverings and method for producing such a mixture The invention relates to a mixture for the production of sub-floors for floor coverings. It is customary to lay such a sub-floor (also called screed) in a thickness of 15 to 30 mm on a raw ceiling and then a walking layer with a thickness of about 5 mm or a top layer of about 4 mm thickness and then a covering made of linoleum, foils made of polyvinyl chloride or another plastic, rubber sheets or parquet applies.



  So far, this screed has mainly been executed as a stone wood screed, i.e. from a mixture of burnt magnesite and chlorine magnesium lye as well as fillers such as sawdust, sawdust, pumice, sometimes with the addition of cork, etc. Fibers such as cotton, Wool, suggested.



  In contrast, the mixture according to the invention is characterized in that, in addition to a binding agent, it has rubber fibers and granular rubber particles as fillers.



  The method according to the invention for producing such a mixture is characterized in that said fillers are obtained by mechanical comminution of old rubber material.



  The mechanical comminution can take place, for example, by tearing, cutting, grinding or rubbing. The following can be used as binders, for example: burnt magnesite with chlorine magnesium lye, polyvinyl acetate or polyvinyl chloride.



  <I> Examples </I> I. 25% rubber fibers 10% granular rubber particles 25% burnt magnesite 40% chloromagnesium lye of 18 Be II.

   20 0/0 rubber fibers 51% granular gium miteilehen 151 / o 'sawdust (softwood) 2211 / o burnt magnesite 38% carbon magnesium lye of 18 B6 III. 251 / o rubber fibers 11% granular rubber particles 641) / o binder mixture,

      produced by mixing 42 parts of a 50 percent polyvinyl acetate = dispersion in water and 22 parts of calcium sulfate containing water of crystallization (CaS04 # 2 H20)

         IV. 2.5% rubber fibers 1.5% granular rubber particles 60% of a 40% dispersion of plasticizer-free polyvinyl chloride in water.
