Description

Schnell anziehender Klebstoff, der aus wässerigen Dispersionen von Polymerisatklebstoffen besteht Die Verwendung von wässerigen Polymerisatdispersionen auf der Grundlage von Polyvinylacetat, Polyvinylpropionat, Polyvi:nylehlorid, Polyvinylid:enchlorid, Polystyrol, Poilyacrylsäureestern sowie Bunalatices und Neoprenelatices als Klebstoffe ist bekannt.Fast-setting adhesive made from aqueous dispersions of Polymer adhesives consist of the use of aqueous polymer dispersions based on polyvinyl acetate, polyvinyl propionate, polyvinyl chloride, polyvinylidene chloride, Polystyrene, polyacrylic acid esters as well as bunalatices and neoprene latices as adhesives is known.

Es ist ferner bekannt, wässerigen Leimen auf Kondensatbasis, wie Harnstoffharzleim und Phenolharzleim, und auf natürlicher Basis, wie Hautleim, Knochenleim und Kaseinleim, pulverförmige Füllstoffe, z. B. Phenodharze, von denen manche in Wasser quellbar sind und Klebeeigenschaften haben, oder mit in Wasser quellbaren überzügen versehene Kunstharzfüllstoffe zuzusetzen. Solche Zusätze dienen aber nur dazu, den Leim zu verbilligen oder zugleich mit der Verbilligung die Konsistenz zu erhöhen oder bei Leimen von sprödem Charakter das spätere Rissigwerden zu verhindern.It is also known to use aqueous condensate-based glues, such as urea resin glue and phenolic resin glue, and on a natural basis, such as hide glue, bone glue and casein glue, powdery fillers, e.g. B. phenolic resins, some of which are water-swellable and have adhesive properties, or with coatings that swell in water Add synthetic resin fillers. Such additives are only used to seal the glue cheaper or at the same time with the cheaper to increase the consistency or at Glues with a brittle character to prevent them from cracking later.

Allen diesen Klebstoffen fehlt aber, insbesondere bei maschineller Verarbeitung, wie beispielsweise schnell laufenden Verpackungsb-eutelmaschinen, das zur Ausnutzung der Leistung solcher Maschinen notwendige Anzugsvermögen.However, all of these adhesives are lacking, especially in the case of mechanical ones Processing, such as high-speed packaging bag machines, the tightening power necessary to utilize the performance of such machines.

Es wurde nun gefunden, daß bei Klebstoffen aus wässerigen Dispersionen von Polymerisatklebstoffen durch den Zusatz von pulverförmigen, im Wasser der Polymerisa:tdispersion quellbaren artgleichen oder artverwandten Podymerisatkunststoffen das Anzugsvermögen ganz erheblich gesteigert werden kann.It has now been found that with adhesives made from aqueous dispersions of polymer adhesives by adding powdery polymer dispersion in the water swellable podymerized plastics of the same or related species have the ability to attract can be increased quite considerably.

So wird beispielsweise bei einem Klebstoff aus einer Dispersion von Po.lyvinylacetat das Anzugsmoment erhöht, wenn diesem Klebstoff das durch Zerstäubungs.tro@cknung gewonnene Polyvinylacetat pulver zugesetzt wird. Gibt man beispielsweise 20"/o eines Po,lyvinylacetatpu;lvens in eine als Klebstoff verwendete Po:lyvinylacetatdispersion, so kann sich das Anzugsmoment um 100 bis 15011/o erhöhen, wie vielfache Versuche gezeigt haben. Dieser gefundene neuartige Effekt hat folgende Erklärung: Die Polyvinylacetatdispersion hat eine durchschnittliche Teilchengröße von 1 bis 5 #t. Das durch Zerstäubungs,trocknung -gewonnene Polyvinylacetatpulver hat dagegen eine Teilchengröße von 10, bis 80 #x. Diese gröberen Teilchen, die in der Dispersion in Schwebe gehalten werden und durch den Wasser-und Weichmachergehalt der Dispersion nur angequollen sind, geben dem aufgetragenen Klebstofffilm eine sofortige hohe Klebewirkung.For example, in the case of an adhesive, a dispersion of Polyvinyl acetate increases the tightening torque when this adhesive is sprayed through recovered polyvinyl acetate powder is added. For example, if you give 20 "/ o one Polyvinyl acetate powder in a polyvinyl acetate dispersion used as an adhesive, so the tightening torque can increase by 100 to 15011 / o, like repeated attempts have shown. This novel effect has the following explanation: The polyvinyl acetate dispersion has an average particle size of 1 to 5 #t. This is done by spray drying Recovered polyvinyl acetate powder, on the other hand, has a particle size of 10 to 80 #x. These coarser particles that are kept in suspension in the dispersion and through the water and plasticizer content of the dispersion are only swollen, give the applied adhesive film an immediate high adhesive effect.

Wenn beispielsweise eine angeleimte Papierbahn mit einer anderen zusammengeführt wird, werden die Teilchen durch die üblicherweise dabei notwendigen Andruckwalzen oder -rollen so zerquetscht, daß die Papierbahnen augenblicklich miteinander verklebt werden.For example, when a glued-on paper web is merged with another is, the particles are usually required by the pressure rollers or rolls so crushed that the paper webs stick together instantly will.

Der Zusatz des pulverförmigen Polyvinylacetats kann in beliebigen Grenzen variiert werden, wobei mit der Erhöhung des Pulverzusatzes, die Beschleunigung des Anzugsmomentes parallel läuft.The addition of the powdery polyvinyl acetate can be in any Limits can be varied, with the increase in the addition of powder, the acceleration of the tightening torque runs in parallel.

In derselben Weise läßt sich auch beispielsweise aus einer Podyacrylsäureesterdisp;ers:ion ein schnell anziehender Klebstoff durch Zusatz von pulverförmigem Po@lyacrylsäu.rees.ter oder Polyvinylacetat oder einem anderen geeigneten, im angequollenen Zustand klebbaren Kunststoff herstellen.In the same way, for example, from a Podyacryläureesterdisp; ers: ion a quick-setting adhesive by adding powdered Po@lyacrylsäu.rees.ter or polyvinyl acetate or another suitable adhesive which can be glued in the swollen state Manufacture plastic.

Es hat sich auch gezeigt, daß das Verfahren in der vorbesahriebenen Weise anwendbar ist auf Latices synthetischer oder natürlicher Herkunft.It has also been shown that the method in the vorbesahrebenen Way is applicable to latexes of synthetic or natural origin.
