Description

Verfahren zur Herstellung hochporöser Leichtstoffe fester und elastischer Natur Zusatz zum Zusatzpatent 936113 Das Patent 913 474 betrifft hochporöse Leichtstoffe fester und elastischer Natur als Bau- und Isolierstoffe bzw. als Schwammaterial, deren Trägersubstanz aus Umsetzungsprodukten von Diisocyanaten oder wie Diisocyanate reagierenden Verbindungen mit solchen höhermolekularen Stoffen besteht, welche mindestens zwei austauschbare mit Isocyanatgruppen reaktionsfähige Gruppen im Molekül enthalten, insbesondere Kondensationsprodukten aus mehrbasischen Säuren und mehrwertigen Alkoholen.Process for the production of highly porous lightweight materials that are stronger and more elastic Nature Addition to additional patent 936113 The patent 913 474 relates to highly porous lightweight materials solid and elastic nature as building and insulating materials or as sponge material, their carrier substance from reaction products of diisocyanates or such as diisocyanates reacting compounds with such higher molecular weight substances consists of at least contain two interchangeable isocyanate-reactive groups in the molecule, in particular condensation products from polybasic acids and polyhydric alcohols.

Gegenstand des Zusatzpatentes 936 113 ist ein spezielles Verfahren zur Herstellung hochporöser Leichtstoffe gemäß Hauptpatent, welches dadurch gekennzeichnet ist, daß bei der Herstellung der Stoffe durch Umsetzung der eingangs erwähnten Komponenten als Treibmittel Wasser oder niedrigmolekulare organische Hydroxyfrerbindungen, jedoch nicht in Emulsion, angewandt werden. The subject of additional patent 936 113 is a special process for the production of highly porous lightweight materials according to the main patent, which is characterized by is that in the manufacture of the substances by reacting the components mentioned above as blowing agent water or low molecular weight organic hydroxyl compounds, however not in emulsion.

Bei der weiteren Bearbeitung der vorliegenden Erfindung wurde nunmehr gefunden, daß an Stelle von Wasser oder niedrigmolekularen organischen Hydroxylverbindnngen mit Vorteil auch kristallwasserhaltige Salze und wasserhaltige, oberflächenaktive Stoffe, die Wasser adsorptiv gebunden enthalten, als Treibmittel verwendet werden können. Further processing of the present invention has now been made found that instead of water or low molecular weight organic hydroxyl compounds Salts containing water of crystallization and water-containing, surface-active salts are also advantageous Substances that contain water bound by adsorption can be used as propellants can.

Als solche seien z. B. kristallwasserhaltiger Borax und feuchte Aktivkohle genannt.As such, z. B. Borax containing water of crystallization and moist activated carbon called.

Die Verwendung dieser Substanzen als Treibmittel führt zu gleichmäßig porösen, festen Schaumstoffen von niedrigem Raumgewicht und hoher Druckfestigkeit, die, wie im Hauptpatent 913 474 und im Zusatzpatent 936 II3 bereits aufgeführt, als Stützmaterial im Bauwesen, als Isoliermaterial für Wärme, Kälte, Schall usw. und für viele andere in den genannten Patentschriften aufgeführte Zwecke verwendet werden können. The use of these substances as propellants leads to evenly porous, solid foams of low density and high compressive strength, which, as already mentioned in main patent 913 474 and additional patent 936 II3, as a support material in construction, as an insulating material for heat, cold, sound, etc. and for many other purposes listed in the patents mentioned can be.

Beispiel I IOO Teilen einer Mischung von Kondensationsprodukten aus Adipinsäure + Phthalsäure + Trimethylpropan und Thiodipropionsäure + Hexantriol mit der Säurezahl 28 werden 5 Teile Borax krist. (Na2 B4 O7 0 Io H20) in einem Kneter zuigemischt. Dieser Mischung werden in einem Rührwerk 65 Teile I,2, 4-Tolaylendiisocyanat unter intensivem Rühren zugefügt. Die Masse wird in Formen gebracht und in einem auf 60 bis 800 geheizten Raum gestellt. Es entsteht ein gleichmäßig poröser, fester Schaumstoff, dessen Raumgewicht 0,045 g/cmS und dessen Druckfestigkeit 3 kg/cm2 beträgt. An Stelle von kristaliwasserhaltigem Borax können auch andere kristallwasserhaltige Salze benutzt werden. Example I 100 Dividing a Mixture of Condensation Products Adipic acid + phthalic acid + trimethylpropane and thiodipropionic acid + hexanetriol with an acid number of 28, 5 parts of borax are crystalline. (Na2 B4 O7 0 Io H20) in a kneader mixed in. 65 parts of 1,2,4-tolaylene diisocyanate are added to this mixture in a stirrer added with vigorous stirring. The mass is brought into forms and in one set to 60 to 800 heated room. The result is a uniformly porous, solid one Foam with a density of 0.045 g / cmS and its compressive strength 3 kg / cm2 amounts to. Instead of borax containing crystalline water, other borax containing crystalline water can also be used Salts are used.

Beispiel 2 IOO Teile eines Kondensationsproduktes aus Adipinsäure + Phthalsäure + Hexantriol mit der Säurezahl 30 werden mit Io Teilen einer Aktivkohle, die einen Wassergehalt von 8 °/o aufweist, in einem Rührwerk gut vermischt. Darauf werden 63 Teile I, 2, 4-Toluylendiisocyanat zugesetzt. Nach grüne lichem Vermischen wird in Formen entleert und darin bei 30 bis 400 stehengelassen. Es -ergibt sich ein fester Leichtstoff, der eine gleichmäßige Porenbildung zeigt. Sein Raumgewicht beträgt 0,07 g/cm3, die Druckfestigkeit 6kg/cm2. An Stelle von wasserhaltiger Aktivkohle können auch andere Stoffe, die Wasser adsorptiv gebunden enthalten, benutzt werden. Example 2 100 parts of a condensation product from adipic acid + Phthalic acid + hexanetriol with the acid number 30 are mixed with Io parts of an activated carbon, which has a water content of 8%, mixed well in a stirrer. Thereon 63 parts of 1,2,4-tolylene diisocyanate are added. After greenish mixing is emptied into molds and left in them at 30 to 400. It surrenders a solid, lightweight material that shows uniform pore formation. Its volume weight is 0.07 g / cm3, the compressive strength is 6kg / cm2. Instead of activated carbon containing water Other substances that contain water bound by adsorption can also be used.
