Description

Verfahren zur Herstellung von Kunstharzdispersionen mit erhöhten Festigkeits- und Wärmeeigenschaften der Festanteile Kunstharzdispersionen finden neuerdings in großem Umfange Verwendung für Spachtelfußböden u. dgl. Die bei der Herstellung der Spachtelbeläge verwandten Bindemittel, z. B. Polyvinylacetat, gehören mit zu den wärmeempfindlichsten der heute bekannten Kunststoffe. So kann es vorkommen, daß in stark geheizten Räumen oder bei Sonneneinstrahlung die Beläge den Druckeinwirkungen z. B. der Stuhl- und Tischbeine nachgeben und mehr oder weniger tiefe Eindrücke hinterlassen.Process for the production of synthetic resin dispersions with increased strength and thermal properties of the solids synthetic resin dispersions have recently been found in large-scale use for leveling floors and the like Filler coverings related binders, e.g. B. polyvinyl acetate are among the most heat-sensitive of the plastics known today. So it can happen that in strongly heated rooms or in direct sunlight, the coverings are subject to pressure z. B. the chair and table legs give way and more or less deep impressions leave behind.

Durch die Erfindung wurde nun festgestellt, daß die oben angeführten Nachteile beseitigt werden, wenn man den Kunstharzdispersionen Chlorkautschuklösungen beimengt. Nachstehender Versuch bestätigt diese Fests@i,-llung: 12o kg Polyvinylacetatdispersion (etwa 72 kg Kunstharzfestanteil und 2,6kgWeichmacher-Dibutylplnthalat), i9,5 kg Eisenoxydfarbe, 22o kg Quarzmehl, 4.5 kg Wasser, 6 kg Chlorkautschuk-Reinbenzollösung (enthaltend 720 g Chlorkautschuk fest).The invention has now found that the above-mentioned disadvantages are eliminated if chlorinated rubber solutions are added to the synthetic resin dispersions. The following experiment confirms this festival: 120 kg polyvinyl acetate dispersion (about 72 kg synthetic resin solids and 2.6 kg plasticizer dibutyl thalate), 19.5 kg iron oxide paint, 220 kg quartz powder, 4.5 kg water, 6 kg chlorinated rubber pure benzene solution (containing 720 g Chlorinated rubber solid).

Die Kunstharzdispersion wurde zunächst mit dem Wasser in einem Rührwerk gründlich gemischt und dann die Chlorkautschuk-Reinbenzollösung unter dauerndem Rühren zugegeben. Die Chlorkautschuklösung war nach etwa io Minuten mit der Kunstharzdispersion völlig durchemulgiert. Hiernach folgte die Zugabe der Eisenoxydfarbe und des Quarzmehls. Ein Teil dieser Masse wurde auf dem Zementestrich bei etwa 2o° C fünfmal aufgespachtelt. Der Belag zeigte nach 8 Tagen bei etwa 2o° C eine wesentlich größere Härte und bei etwa 50° C etwa die doppelte Härte als bei derselben Zusammensetzung ohne Chlorkautschuk.The synthetic resin dispersion was first mixed with the water in a stirrer thoroughly mixed and then the chlorinated rubber pure benzene solution under constant Stirring added. The chlorinated rubber solution was with the synthetic resin dispersion after about 10 minutes completely emulsified. This was followed by the addition of the iron oxide paint and the quartz flour. A part of this mass was applied five times on the cement screed at about 20 ° C. After 8 days at about 20 ° C, the covering showed a significantly greater hardness and at about 50 ° C about twice the hardness of the same composition without chlorinated rubber.

Ein weiterer Versuch mit der doppelten Menge Chlorkautschuk-Reinbenzollösung zeigte noch etwas höhere Werte. Obwohl beim obigen Versuch nur etwa I °/o- Chlorkautschuk vom Kunstharzfestanteil angewandt worden ist, war die außerordentlich schnelle Erhärtung der einzelnen Spachtelgänge so beeindruckend, daß die hiermit erzielten Beläge schon nach wenigen Stunden Härtegrade aufwiesen, die von denselben Mischungen ohne Chlorkautschuk auch nicht annähernd erreicht wurden.Another experiment with twice the amount of chlorinated rubber pure benzene solution showed slightly higher values. Although only about The use of 100% chlorinated rubber from the synthetic resin solids was exceptional rapid hardening of the individual filler passages so impressive that this After just a few hours, the coverings obtained showed a degree of hardness that was achieved by the same Mixtures without chlorinated rubber were not even remotely achieved.

Das Verfahren kann Anwendung finden für die wäßrigen Kunstharzdispersionen der Polyvinylacetate und deren Mischpolymerisate, des Polyvinylchlorids und der Polyacrylsäureester und der Mischpolymerisate verschiedener Acrylsiäureester.The process can be used for the aqueous synthetic resin dispersions of polyvinyl acetates and their copolymers, of polyvinyl chloride and of Polyacrylic acid esters and the copolymers of various acrylic acid esters.

Die Verträglichkeit von Chlorkautschuk mit in einem Lösungsmittel gelösten Polyvinylacetat ist bekannt. Nicht bekannt ist die Einverleibungvon Chlorkautschuklösungen in eine Kunstharzdispersion. Es war auch nicht naheliegend, Chlorkautschuk, gelöst in einem in Wasser unlöslichen Lösungsmittel, einer Kunstharzdispersion zuzufügen, ohne dabei das Dispersionsgemisch sofort zu zerstören bzw. zur Koagulierung zu bringen.The compatibility of chlorinated rubber with in a solvent dissolved polyvinyl acetate is known. The incorporation of chlorinated rubber solutions is not known in a synthetic resin dispersion. It wasn't obvious either, chlorinated rubber, dissolved in a water-insoluble solvent to add to a synthetic resin dispersion, without immediately destroying or coagulating the dispersion mixture.

Durch empirische Versuche können die entsprechenden Mengen Chlorkautschuk für den jeweiligen Verwendungszweck leicht ermittelt werden. Auch kann die Menge des betreffenden Lösungsmittels für Chlorkautschuk, z. B. Benzol, erhöht oder ermäßigt werden. Dispersionen von Mischpolymerisaten oder Polyvinylchloriden müssen gegebenenfalls zur Erhöhung der Dispersionsbeständigkeit mit Polyvinylacetatdispersionen vermischt werden.The appropriate amounts of chlorinated rubber can be determined by empirical tests can easily be determined for the respective purpose. The crowd can too of the solvent in question for chlorinated rubber, e.g. B. Benzene, increased or decreased will. Dispersions of copolymers or polyvinyl chlorides may have to be mixed with polyvinyl acetate dispersions to increase dispersion resistance will.

Ähnliche Ergebnisse wie mit Chlorkautschuk erzielt man auch mit anderen mit Polyv inylacetat verträglichen Kunststoffen, wie z. B. hochchloriertem Diphenylharz.Results similar to those obtained with chlorinated rubber can also be achieved with others with polyvinyl acetate compatible plastics such. B. highly chlorinated diphenyl resin.
