Verfahren zum kontinuierlichen Mischen von Phenolharz für Schäumzwecke mit nicht löslichen FeststoffenProcess for the continuous mixing of phenolic resin for foaming purposes with insoluble solids

Die Erfindung "bezieht sich auf ein Verfahren zum kontinuierlichen Mischen von Phenolharz für Schäumzwecke mit nicht μ löslichen Feststoffen wie Härter in Pulverform, Agglomeraten, faserigen Stoffen, z. B. Glas- und/oder Asbestfasern. The invention "refers to a method for continuous mixing of phenol resin for Schäumzwecke with non-μ-soluble solids such as curing agents in powder form agglomerates, fibrous substances, for. Example, glass and / or asbestos fibers.

Phenolharzschaumstoffelemente mit Füllstoffen wie z.B. Glasfasern zeichnen sich gegenüber ungefüllten Phenolharzschaumstoffelementen sowohl durch eine wesentlich höhere Festigkeit als auch durch ein günstigeres Brandverhalten aus. Zum Einmischen faseriger Feststoffe sind normale Rührer jedoch ungeeignet, weil sich die Fasern der Stoffe um die Mischelemente schlingen und dadurch die Mischkammer in verhältnismäßig kurzer Zeit verstopft wird, so daß ein reibungsloser Betrieb nicht gewährleistet ist.Phenolic resin foam elements with fillers such as glass fibers Compared to unfilled phenolic resin foam elements, they are characterized by a significantly higher strength as well as a more favorable fire behavior. However, normal stirrers are unsuitable for mixing in fibrous solids. because the fibers of the fabrics wrap around the mixing elements and thus the mixing chamber in proportion becomes clogged for a short time, so that smooth operation is not guaranteed.

Zur Vermeidung dieses Nachteils sieht die Erfindung vor, als Mischkammer eine Doppelschnecke einem ersten mit.zunehmenden Gangvolumen ausgebildeten Förderteil und einem anschließenden mit einer Anzahl von gleichmäßig über den Umfang verteilt angeordneten radialen Stegen od.dgl. ausgebildeten Mischteil zu verwenden, wobei dieser vom hinteren nach dem vorderen Ende zu aufeinanderfolgend der oder die Feststoffe und schließlich das schäumbare Phenolharz zugeführt werden und ferner sieht die Erfindung vor, die Mischzeit wesentlich kürzer zu halten als die Reaktionszeit des Harzes ist.To avoid this disadvantage, the invention provides for a double screw to be taken along as the mixing chamber Corridor volume trained conveying part and a subsequent with a number of evenly distributed over the circumference radial webs or the like. trained mixing part to use, this from the rear to the front end to successively the solids and finally the foamable phenolic resin are supplied and also sees the invention proposes to keep the mixing time much shorter than the reaction time of the resin.

Die Schneckengeometrie ist dabei selbstverständlich, so gewählt, daß das Fördervolumen vom Einzug her entsprechend der jeweils zudosierten Menge bzw. Mengen ansteigt. Zweckmäßig ist es ferner, eng-kämmende Schnecken zu verwenden, so daß sich deren Planken selbst reinigen.The screw geometry is a matter of course, see above chosen that the delivery volume increases from the intake according to the respective added amount or amounts. Appropriate it is also to use tight-meshing snails so that their planks clean themselves.

Um zu verhindern, daß mit den eingetragenen Peststoffen Luft in die Mischung gelangt, deren homogene Verteilung in der Schnecke nicht mehr möglich ist und die daher zur Folge hat, daß im fertigen Schaumteil Luftblasen bzw. Lunker zu finden sind, wird in zweckmäßiger weiterer Ausbildung der Erfindung vorgesehen, den Ort für die Eintragung des bzw. der Feststoffe und die Poppelschnecke unter' der Atmosphäre eines in schäumfähigem Phenolharz-Treibmittel-Gemisch löslichen Schutzgases zu halten. Das Schutzgas, beipielsweise Frigen, verdrängt die Luft und wird, da es sich im Phenol-Schaumgemisch löst, einwandfrei verteilt, so daß Lunker in fertigen Schaumteil nicht vorhanden sind.To prevent having the registered pesticides Air gets into the mixture, the homogeneous distribution of which in the screw is no longer possible and which therefore results has that air bubbles or voids are to be found in the finished foam part, in an expedient further training the Invention provided the place for the entry of the solids and the Poppelschnecke under 'the atmosphere a protective gas soluble in a foamable phenolic resin-propellant mixture. The protective gas, for example Freezing, displaces the air and, since it dissolves in the phenol-foam mixture, is perfectly distributed, so that voids are formed are not present in finished foam part.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeipiei gezeigt und wird anhand dieses im folgenden noch erläutert. Es zeigenThe invention is shown in one embodiment in the drawing shown and will be explained in the following on the basis of this. Show it

Der Doppelschnecke 8 wird über den Einfüllstutzen 1 ein nicht gezeigter Feststoff, beipielsweise Glasfasern, ggf. auch eine Feststoffmischung zugeführt. Der Einfüllstutzen dient zum Eintragen eines pulverförmigen Härters und der Einfüllstutzen 3 schließlich zum Eintragen des Phenolharz-The double screw 8 is fed via the filler neck 1 a solid, not shown, for example glass fibers, possibly also fed a solid mixture.

Ebenso könnten auch die Einfüllstutzen 1 und 2 zusammengefaßt werden, wenn der Peststoff und der Härter zusammen eingegeben werden.Propellant mixture. If the screw has a phenolic propellant hardener mixture is supplied, the filler neck 2 and 3 can of course become a filler neck be summarized. Likewise, the filler necks 1 and 2 could be combined when the The pesticide and the hardener are entered together.
