Abstract

Foams for backing textiles, esp. floor coverings, are made from a PVC paste which contains 25-35% copolymer emulsion PVC of 5-15 mu, average particle size including 8-10% polyvinyl acetate, 30-40% quickly gelling plasticiser, 25-35% ground crystallised CaCO3 of 20-40 mu particle size as filler, 1-2% blowing agent decomposing at 135 degrees C. and 1-2% stabilisers. Pref. 5-morpholyl-1,2,3,4-thiatriazole is blowing agent used, and pref. PVC pastes contain Ba-, Cd- and/or Zn stabilisers.

Description

Polyvinylchlorid-Paste Die Erfindung bezieht sich auf eine Polyvinylchlorid-Paste, die aus Emulsions-Polyvinylchlorid, Weichmacher und Füllstoffen besteht und bei einer Erhitzung ein Gas abspaltendes Treibmittel aufweist sowie für eine Schaumbildung bei einer um 133 oC liegenden Temperatur vorgesehen ist. Polyvinyl chloride paste The invention relates to a polyvinyl chloride paste, which consists of emulsion polyvinyl chloride, plasticizers and fillers and at a heating has a gas-releasing propellant and for a foam formation at a temperature of around 133 oC.

Polyvinylchlorid-Pasten dieser Art werden häufig zum Beschichten textiler Materialien, wie vor allem von Bodenbelägen, verwendet. Dabei ist es wesentlich, dass bei der Behandlung bestimmte Temperaturgrenzen eingehalten werden, oberhalb welcher das textile Material in irgendeiner Weise beschädigt werden würde. Insbesondere sind die Farbstoffe sowie die häufig aus Kunststoffen bestehenden Fasermaterialien des textilen Materials sehr temperaturempfindlich. Man kann bestimmte Zusammensetzungen von Polyvinylchlorid-Pasten der bekannten Art für diesen Zweck verwenden, doch ist dabei der sowohl aus Qualitätsgründen als auch aus Gründen der Kostenersparnis an gestrebte Füllstoffgehält sehr gering. Als Füllstoff inden üblicherweise die von der Kautschukverarbeitung her bekaJinten tiaterialien Verwendung, wie zum Beispiel Calciumcarbonat, Calciumsilikat, Natriumaluminosilikat, pyrogene Kieselsäure, Kieselkreide, Caolin, Schwerspat, Magnesiumcarbonat und dergl Massgeblich für die Wirkung eines derartigen Füllstoffes sind stets die Teilchengrösse, die geometrische Gestalt der Teilchen und die chemische Zusammensetzung Im Hinblick auf die beabsichtigte Wirkung sind daher die genannten Parameter der Füllstoffe niit grosser Sorgfalt einzuhalten.Polyvinyl chloride pastes of this type are often used for coating textiles Materials used, especially for floor coverings. It is essential that that certain temperature limits are adhered to during the treatment, above which the textile material would be damaged in any way. In particular are the dyes and the fiber materials, which are often made of plastics of the textile material is very temperature-sensitive. You can have certain compositions of polyvinyl chloride pastes of the known type for this purpose, but is both for quality reasons and for reasons of cost savings aspired filler content is very low. As a filler usually those of In rubber processing, ink materials were used, for example Calcium carbonate, calcium silicate, sodium aluminosilicate, fumed silica, siliceous chalk, Caolin, barite, magnesium carbonate and the like Relevant for the effect of such a filler is always the particle size, the geometric one Shape of the particles and chemical composition In terms of the intended The parameters of the fillers mentioned are therefore effective with great care to be observed.

Der Erfindung liegt die Aufgabe zugrunde , eine Polyvinylchloridpaste der einleitend beschriebenen Art zu schaffen, bei der die Qualität der daraus erzeugten Schaumstoffe besser als diejenige bei den bekannten Pasten ist und die weiterhin in der Herstellung auch preiswerter ist Dies wird erfirdungsgemäss dadurch erreicht, dass sie zwischen 25-35% copolymeres Enulsions-PVC einer mittleren Korngrösse von 5-15 µ einschliesslich 8-10% Polyvinylacetat, zwischen 30-40% schnell gelierenden Weichmacher, zwischen 25-35% aufgemanlenes, kristallisiertes Calciumcarbonat einer mittleren Korngrösse von 20-40 µ, zwischen 1-2% bei etwa 135°C spaltbares Treibmittel und zwischen 1-2 % Stabilisatoren enthält.The invention is based on the object of a polyvinyl chloride paste of the type described in the introduction, with the quality of the resulting Foams are better than that of the known pastes and continue to do so is also cheaper to manufacture This is achieved according to the invention by that they contain between 25-35% copolymeric enulsion PVC with a mean grain size of 5-15 µ including 8-10% polyvinyl acetate, between 30-40% fast-setting Plasticizer, between 25-35% grained, crystallized calcium carbonate mean grain size of 20-40 µ, between 1-2% at about 135 ° C fissile blowing agent and contains between 1-2% stabilizers.

Überraschenderweise kommt man bei einer derartig hoch gefüllten Paste auch bei einer niedrigen, um 135° liegenden Galier- bzw. Schäumtemperatur zu einem Schaum hervorragender Abrbfestigkeit und Strukturfestigkeit bei einer guten Volumenzunahme durch den Schäumungsprozess.Surprisingly, you get such a highly filled paste even at a low galling or foaming temperature of around 135 ° Foam with excellent abrasion resistance and structural strength with a good increase in volume through the foaming process.

Als Weichmacher der vorgeschlegenen Art kommen alkylierte Sulfonsäureester des Phenols und Kresols, Dioktyl-Phthalat Benzyl- und Bulylphtalat in Frage.Alkylated sulfonic acid esters are used as plasticizers of the type proposed of phenol and cresol, dioctyl phthalate Benzyl and bulyl phthalate in question.

Als Treibmittel eignet sich insbesondere 5-Morpholyl-1,2,3,4-thiatriazol.A particularly suitable propellant is 5-morpholyl-1,2,3,4-thiatriazole.

Weiterhin gelangen zweckmässig Da-, Od- und Zn-Stabilisatoren zurArwendung. Auf die sonst üblichen Kicker wird bei der neuen Paste hingegen verzichtet.Furthermore, Da, Od and Zn stabilizers are expediently used. On the other hand, the usual kickers are dispensed with with the new paste.

Mit der neuen Polyvinylchloridpaste konnten erfolgreich sehr empfindliche Bodenbelagmaterialien rückseitig beschichtet werden. Die Beschichtung liess sich im Anschluss an den Gelierprozess unter Verwendung gekühlter Prögewalzen profilieren, so dass sich ein Eindringen des Schaumes in die Struktur des forundgewebes und als Folge davon eine gute Haftung zwischen der Beschichtung und dem Grundgewebe ergab-With the new polyvinyl chloride paste, very sensitive Flooring materials are coated on the back. The coating left profiling after the gelling process using cooled embossing rollers, so that a penetration of the foam into the structure of the forundgewebes and as As a result, good adhesion between the coating and the base fabric resulted-
