Description
Verfahren zur Herstellung von hitzebestindigen organischen Sohaumstoffgebilden Zusatz zu Patent 0.... ... ... (Patentanmeldung B 74 874 IVc/39 b) Gegenstand des Patentes e ... ... (Patentanmeldung B 74 874 IVc/39 b) ist ein Verfahren zur Herstellung von hitzebeständigen organischen Schaumstoffgebilden, die mit Alkalisilikaten kombiniert sind. Diese Schaumstoffgebilde werden dadurch hergestellt, daß man verschäumbare feinteilige Kunststoffe in eine wässerige alkalisilikathaltige Lösung mit gegebenenfalls darin suspendierten wässerigen Alkalisilikaten in einer solchen Menge einüringt, daß die Menge der zugesetzten Kunststoffteilchen zur Menge der in der Ladung bzw. Suspension enthaltenen'wasserfreien Substanzen sich wie 1 : 9 bis 9 : 1 verhält. Diese Mischung wird anschließend gegebenenfalls bei Temperaturen unterhalb der Temperatur, bei der die feinteiligen Kunststoffe schäumen, verfestigt und anschließend bei Temperaturen oberhalb des Erweichungspunktes der verschäumbaren Kunststoffe zu einem homogenen Schaumgebilde verschäumt. Die so hergestellten Schaumstoffe zeichnen sich durch eine hohe mechanische Stabilität aus. Wesentlich ist, daß auch bei der Einwirkung hoher Temperaturen die anorganische GerUstsubstanz erhalten bleibt, die aufgrund ihrer Porosität noch eine erhebliche brandhemmende Wirkung besitzt. Will man nach diesem Verfahren dickere Schichten herstellen, deren Dicke beispielsweise 60 mm übersteigt, so erhält man Schaumstoffgebilde, die teilweise inhomogen sind.Process for the production of heat-resistant organic foam structures Addition to patent 0 .... ... ... (patent application B 74 874 IVc / 39 b) subject of the Patentes e ... ... (patent application B 74 874 IVc / 39 b) is a manufacturing process of heat-resistant organic foam structures combined with alkali silicates are. These foam structures are produced by being foamable fine-particle plastics in an aqueous alkali-silicate-containing solution with optionally constricts aqueous alkali silicates suspended therein in such an amount, that the amount of plastic particles added to the amount of the cargo or Anhydrous substances contained in the suspension behave as 1: 9 to 9: 1. This mixture is then optionally at temperatures below the temperature in which the finely divided plastics foam, solidify and then at temperatures above the softening point of the foamable plastics to a homogeneous one Foam structure foamed. The so produced Draw foams are characterized by high mechanical stability. It is essential that the Exposure to high temperatures the inorganic framework is retained due to its porosity still has a considerable fire-retardant effect. Want you produce thicker layers according to this process, their thickness for example If it exceeds 60 mm, foam structures are obtained, some of which are inhomogeneous.
Es wurde nun gefunden, daß man auch bei dickeren Schichten homogene Schaumkörper erhält, wenn man den alkalisilikathaltigen Lösungen oder Suspensionen bereits vorgeschäumte, aber noch blähfähige Partikeln zusetzt.It has now been found that even thicker layers are homogeneous Foam body is obtained when the alkali-silicate-containing solutions or suspensions already pre-expanded but still expandable particles adds.
Man kann beispielsweise von einem Gemisch mit einer Schichtdicke von 20 bis 30 mm ausgehen und dieses nach der Erwärmung zu einem Schaumgebilde mit einer Dicke von 30 bis 6o mm aufschäumen. Wie in der Hauptanmeldung angegeben, eignen sich als Kunststoffpartikeln solehe aus Polystyrol oder aus Styrol enthaltenden Mischpolymerisaten, z.B. solche aus Styrol und Acrylnitril, Acrylsäure oder Butadien. Auch Kunststoffpartikeln auf Basis von Vinylchlorid oder Vinylidenchlorid sind geeignet. Die Partikeln werden nur so weit vorgeschäumt, daß sie bei der weiteren Verschäumung bei der Merstellung der Schaumgebilde mindestens noch eine Volumenzunahme von 5 % erfahren. Im Falle von Polystyrolteilchen, die in nichtgeschäumtem Zustand ein Schüttgewicht von 450 bis 750 g/l aufweisen, kann man diese so weit vorschäumen, daß sich ihr Schüttgewicht auf etwa 20 bis 300 g/l erniedrigt.One can, for example, from a mixture with a layer thickness of Go out 20 to 30 mm and this after heating to form a foam structure with a Foam a thickness of 30 to 60 mm. As stated in the main application, are suitable containing themselves as plastic particles made of polystyrene or of styrene Copolymers, e.g. those made from styrene and acrylonitrile, acrylic acid or butadiene. Plastic particles based on vinyl chloride or vinylidene chloride are also suitable. The particles are only pre-expanded to such an extent that they can be expanded during further expansion When creating the foam structure, there is at least another 5 increase in volume % Experienced. In the case of polystyrene particles, which are in a non-foamed state Have a bulk density of 450 to 750 g / l, they can be pre-expanded to such an extent that that their bulk density is reduced to about 20 to 300 g / l.
Wie in der Hauptanmeldung angegeben, ist es vorteilhaft, den alkalisilikathaltigen Lösungen oder Suspensionen Stoffe zuzusetzen, die diese in wasserunlösliche Silikate überführen Beispielsweise kommen Verbindungen der Erdalkalimetalle, z.B. Calclumcarbonat, Magnesiumoxyd oder Zinkoxyd, in Betracht.As stated in the main application, it is advantageous to use the alkali silicate Adding substances to solutions or suspensions, which convert them into water-insoluble silicates For example, compounds of the alkaline earth metals, e.g. calcium carbonate, Magnesium oxide or zinc oxide into consideration.
Nach dem erfindungsgemäßen Verfahren kann man von stärkeren Schichten ausgehen, die nach der Erwärmung einen homogenen Schaumkörper ergeben. Diese Schaumkörper zeichnen sich ferner dadurch aus, daß sie einegleichmäßigere Oberfläche aufweisen als dies beim Einsatz von nichtgeschäumten Partikeln der Fall ist.The process according to the invention can be used to produce thicker layers go out, which after heating result in a homogeneous foam body. This foam body are also distinguished by the fact that they have a more uniform surface than is the case when using non-foamed particles.
Die erfindungsgemä# hergestellten Schaumstoffgebiide können als brandschützende und thermisch isolierende Schichten eingesetzt werden. Sie eignen sich insbesondere als Zwischen schichten in Verbundelementen, z.B. in Kombination mit Holz, Asbestzementplatten, Metallplatten, Kunststoffplatten, Gipsplatten und dergleichen.The foam structures produced according to the invention can be used as fire-protective and thermally insulating layers are used. They are particularly suitable as intermediate layers in composite elements, e.g. in combination with wood, asbestos cement panels, Metal panels, plastic panels, plasterboard and the like.
Beispiel 45 Gewichtsteile blähfähige Polystyrolteilchen, die als Treibmittel 8 % Pentan enthalten und deren Durchmesser durchschnittlich 0,5 mm beträgt, werden unter der Einwirkung von 1000C heißem Wasserdampf so weit vorgeschäumt, daß sich ihr Schüttgewicht auf 50 g/l erniedrigt. Die so. vorne schäumten Teilchen werden mit 100 Gewichtsteilen NatriVmwasserglaspulver mit -einem Wassergehalt von 16 Gew.-% und einer Teilchengröße von etwa 0>1 mm, 100 Gewichtsteilen Natriumwasserglaslösung mit einer Konzentration von 39°Be, 50 Gewichtsteilen Zinkoxyd und 25 Gewichtsteilen Magnesiumoxyd vermischt. Das Gemisch wird in einen mit einer Polyamidfolie ausgelegten Behälter in einer Schichthöhe von 40 mm eingebracht und eine Stunde lang bei 1000C gelagert. Example 45 parts by weight of expandable polystyrene particles which are used as Propellants contain 8% pentane and their diameter is average 0.5 mm, are pre-expanded under the action of 1000C hot steam to the extent that that their bulk density is reduced to 50 g / l. The so. particles foamed at the front 100 parts by weight of sodium water glass powder with a water content of 16% by weight and a particle size of about 0> 1 mm, 100 parts by weight of sodium waterglass solution with a concentration of 39 ° Be, 50 parts by weight of zinc oxide and 25 parts by weight Magnesium oxide mixed. The mixture is lined with a polyamide film Container placed at a layer height of 40 mm and for one hour at 1000C stored.
Es entsteht ein etwa 50 mm hohes Schaumstoffgebilde, das eine gleichmäßige Oberfläche und eine einheitliche Struktur aufweist. Der Schaumstoff hat ein Raumgewicht von 215g/l.The result is an approximately 50 mm high foam structure, which is uniform Surface and has a uniform structure. The foam has a density of 215g / l.
Auf den Schaumstoff werden beidseitig zwei Eisenbleche von Je 1 mm Stärke mit einer Wasserglaslösung, die pro 200 Gewichtsteile 50 Gewichtsteile Talkum enthält, aufgeklebt.Two iron sheets of 1 mm each are placed on both sides of the foam Starch with a water glass solution containing 50 parts by weight of talc per 200 parts by weight contains, glued on.
Beim Beflammen dieser Probe gemäß der Brandeinheitskurve nach DIN 4102 wird nach mehr als 60 Minuten an der dem Brand abgekehrten Seite eine Temperatur von etwa 1400C gemessen. Ein derartiges Element kann daher gemäß DIN 4102 in die Feuerwiderstandsklasse F 60 eingereiht werden. Die brandhemmenden Eigenschaften des Schaumstoffgebildes können weiter gesteigert werden, wenn man auf seine Oberfläche anstelle der Eisenbleche Asbestzementplatten oder Gipsplatten aufbringt.When flaming this sample according to the fire unit curve according to DIN 4102 becomes a temperature on the side facing away from the fire after more than 60 minutes measured from about 1400C. Such an element can therefore in accordance with DIN 4102 in the Fire resistance class F 60 can be classified. The fire retardant properties of the foam structure can be further increased if you look at its surface instead of the iron sheets, applies asbestos cement panels or plasterboard.
