Ausserdem sind auch Polyvinylchloridfilme schon als Deckenschichten auf eine Polyurethanschaumschicht aufgeklebt worden, um einen elastischen Schichtstoff zu bilden.Laminates made from fabric underlays, plastic foam interlayer and homogeneous plastic cover layer, in which the Foam intermediate layer and the homogeneous basin layer are made of polyvinyl chloride, which laminates of leather-like Condition are, ss.B. so get that on one homogeneous polyvinyl chloride layers a polyvinyl chloride dispersion containing blowing agent applied and after laying on a fabric this middle layer is expanded by heating. In addition, polyvinyl chloride films are also already used as top layers has been glued to a polyurethane foam layer to form an elastic laminate.

Durch die vorliegende Erfindung werden nun die vorteilhaften Eigenschaften des Polyurethans in Schichtstoffen beibehalten und mit denjenigen des Polyvinylchlorids kombiniert, wobei in überraschender Weise die unangenehmen Eigenschaften beider Schichten weitgehend unterdrückt werden. Nach der vorliegendenThe present invention now maintains the advantageous properties of polyurethane in laminates and combined with those of polyvinyl chloride, surprisingly the unpleasant properties of both Layers are largely suppressed.

Gegebenenfalls kann ein Teil der Polyurethansohaumabfälle durch Schaumgummi oder Polyvinylchloridschaum ersetzt werden. Dann werden 18 Gewichte teile eines Klebemittels aus 7 Gewichtsteilen Adipinsäureglykolester, 7 dewichtateilen Methylenchlorid und 4 Gewichtsteilen Soluylendiisocyanat vorbereitet und dieses Klebemittel auf einer Mischmaschine mit den Schaumstoff teilchen innig vermischt und die Mischung in Formen vergossen. Kach etwa 3-5 Minuten setzt unter leichter Temperaturerhöhung das Verschäumen des Polyurethanbindemittels ein. Nach Abklingen der Reaktion wird abkühlen gelassen und der platten- ) förmige Verbundstoff aus der Form entnommen. In der vorstehend beschriebenen Zusammensetzung des Klebemittels kann aber auch •in foil des Polyesters durch eine wässrig® Methyleellulose-Itisung ersetzt werden. Ein günstiges Verhältnis sind 40 Teile Polyester su 2 !«ilen einer 4 £-igea MethyleelluXosaldeung« Pie Hethyleellulose verbessert die Verteilung des klebemittel® und wirkt eich auch auf die mechanischen Eigenschaften, des hergestellten FonokörperB aus, da sie dem fertigen Gegenstand eine erhöhte Geschmeidigkeit verleiht.The agglomerate of foam * that forms the middle layer. particles, can be produced, for example, as follows: 80 parts by weight of polyurethane foam waste are comminuted on a knife mill to a particle size of about 8-10 mm. If necessary, some of the polyurethane foam waste can be replaced by foam rubber or polyvinyl chloride foam. Then 18 parts by weight of an adhesive made of 7 parts by weight of adipic acid glycol ester, 7 parts by weight of methylene chloride and 4 parts by weight of solvent diisocyanate are prepared and this adhesive is intimately mixed with the foam particles on a mixer and the mixture is poured into molds. After about 3-5 minutes, the foaming of the polyurethane binder starts with a slight increase in temperature. After the reaction is allowed to cool and taken out of the plate-like) shaped composite from the mold. In the above-described composition of the adhesive, however, the polyester can also be replaced by an aqueous® methylcellulose solution in foil. A favorable ratio is 40 parts of polyester su 2! «Ilen of a 4-pound methyleelluXosaldeung« Pie Hethyleellulose improves the distribution of the adhesive® and also has an effect on the mechanical properties of the manufactured FonobodyB, since it gives the finished object an increased suppleness .
