Abstract
Description
Verfahren zur Herstellung von Bauteilen, insbesondere von Bauplatten sowie von GemischenProcess for the production of components, in particular building boards and mixtures
Die Erfindung betrifft ein Verfahren zur Herstellung von Bauteilen, insbesondere von Bauplatten sowie von Gemischen, wobei als Bindemittel ein thermisch behandeltes Gemisch aus Verbrennungsrückständen, wasserhaltigen Substanzen und CaO zum Einsatz kommt.The invention relates to a method for producing components, in particular building boards and mixtures, a thermally treated mixture of combustion residues, water-containing substances and CaO being used as the binder.
Bekannt ist es, aus dem bei der nassen Rauchgasentschwefelung entstehen- den Gips Wandplatten, sogenannte Gipskartonplatten, herzustellen. Diese Platten sind aufgrund ihrer mangelnden Wasser- und Witterungsbeständigkeit ausschließlich für den Innenausbau von Gebäuden einsetzbar.It is known to produce wall panels, so-called gypsum plasterboard, from the gypsum produced in the wet flue gas desulfurization. Due to their lack of water and weather resistance, these panels can only be used for the interior construction of buildings.
Weiterhin ist es bekannt, auf Gipsbasis nach dem Aufwickelverfahren Bauroh- platten herzustellen, die neben dem in Form von CaSO4 • 1/2 H2O vorliegenden Gips auch Zement, Schlacken, Flugaschen, Kieselgur, Sand, mineralische und organische Fasern und Flockungshilfsmittel beinhalten (DE-OS 3121256).Furthermore, it is known to produce gypsum-based building boards using the winding method, which in addition to the gypsum present in the form of CaSO4 • 1/2 H2O also contain cement, slags, fly ash, diatomaceous earth, sand, mineral and organic fibers and flocculants (DE- OS 3121256).
Darüber hinaus gibt es leichte, nichttragende Trennwände aus nachwachsen- den Rohstoffen, wie Flachs, Hanf, Stroh oder dgl. und Gips (DE-GM 297 14 805, 296 20 751 ). Alle diese Platten und Trennwände weisen den bereits bei den Gipskartonplatten beschriebenen Mangel einer ausschließlichen Verwendbarkeit für den Innenausbau auf. Des weiteren sind ihre Festigkeits- und Elastizitätswerte sehr niedrig, so daß die Einsatzgebiete auch dort stark einge- schränkt sind.In addition, there are light, non-load-bearing partitions made from renewable raw materials, such as flax, hemp, straw or the like, and gypsum (DE-GM 297 14 805, 296 20 751). All of these panels and partitions have the lack of exclusive usability already described for the gypsum plasterboard for interior construction. Furthermore, their strength and elasticity values are very low, so that the areas of application are also severely restricted there.
Als Bindemittel für Bauplatten sind Zement, α- und ß-Halbhydrat aus Natur-Gips bzw. REA-Gips bekannt.Cement, α- and β-hemihydrate made of natural gypsum or REA gypsum are known as binders for building boards.
Zur Immobilisierung von Schadstoffen ist ein Verfahren zur Herstellung eines Bindemittels bekannt, wobei die Ausgangsstoffe für die Speicherkomponenten aus Verbrennungsrückständen, wasserhaltigen Substanzen und CaO gemischt und einer speziellen thermischen Behandlung unterzogen werden (DE 197 19 684). Ein baustofftechnischer Einsatz dieses Produkts ist nicht näher beschrieben. Weiterhin ist ein thermisches Verfahren bekannt, bei welchem Schaumglasprodukte mit granulatartigen Eigenschaften aus Flugstaub oder Flugasche sowie Alkalisilikaten hergestellt werden, wobei Flugstaub und Alkalisilikat- oder Alkalihydroxidlösungen sowie Wasser vermischt, das Gemisch durch mehrstündiges Erwärmen auf bis zu 100 °C zum Erhärten gebracht, die abgekühlte Masse zerkleinert, eine Fraktion von < 1 ,6 und > 3, 15 mm abgesiebt und das erhaltene Produkt durch eine erneute Wärmebehandlung bei 150 - 300 °C aufgebläht (25 - 35 Minuten) wird (DE-OS 31 36 888). Das entsprechende Produkt ist für Isolierzwecke einsetzbar. Der Herstellungsprozeß verdeutlicht, , daß das auf eine derart aufwendigen Art und Weise gefertigte Granulat nur unter Verwendung großer Energie- und Technologieaufwendungen produzierbar ist, was sich zweifellos auf seinen Preis auswirken muß.A process for the production of a binder is known for the immobilization of pollutants, the starting materials for the storage components being mixed from combustion residues, water-containing substances and CaO and subjected to a special thermal treatment (DE 197 19 684). The use of this product in building materials is not described in detail. Furthermore, a thermal process is known in which foam glass products with granular properties are produced from fly dust or fly ash and alkali silicates, whereby fly dust and alkali silicate or alkali hydroxide solutions and water are mixed, the mixture is hardened by heating for several hours at up to 100 ° C, which cooled Crushed mass, a fraction of <1, 6 and> 3, 15 mm sieved and the product obtained is inflated by renewed heat treatment at 150-300 ° C (25-35 minutes) (DE-OS 31 36 888). The corresponding product can be used for insulation purposes. The manufacturing process shows that the granulate produced in such a complex manner can only be produced using large amounts of energy and technology, which undoubtedly has to have an impact on its price.
Es ist bekannt, Glas/Altglas, auch als Recycling, mit gelöstem Natronsilikat, in dem Mineralien, Glasbildner, Schmelzfluß- und Treibmittel gelöst sind, kontinuierlich in einem Reaktions-Mischer einzubringen, das entstehende Gemenge zu granulieren, zu trocknen und bei ca. 800 °C zu Schaumglasgranulat oder - platten von geringer Dichte zu schäumen sowie diese Produkte im Weiteren als Isolierstoff in zementgebundenem Konstruktions-Leichtbeton, Isolierbeton, - mörtel, -platten, -estrich, Schüttisolation und zur Steinefertigung mit Isolierwirkung einzusetzen (DE-OS 39 41 732).It is known to continuously introduce glass / waste glass, also as recycling, with dissolved sodium silicate in which minerals, glass formers, melt flow and blowing agents are dissolved in a reaction mixer, to granulate the resulting mixture, to dry it and to dry it at approx. 800 ° C to foam foam granules or slabs of low density and to use these products as an insulating material in cement-bound lightweight construction concrete, insulating concrete, mortar, slabs, screed, bulk insulation and for stone production with insulating effect (DE-OS 39 41 732 ).
Der Einsatz von Schaumglasgranulat aus Recyclingglas als Leichtzuschlag in zementgebundenen Leichtmörteln sowie -betonen und Wärmedämmputzen ist aus DE-OS 43 42 996 bekannt.DE-OS 43 42 996 discloses the use of foam glass granulate made from recycled glass as a lightweight aggregate in cement-bound lightweight mortars and concretes and thermal insulation plasters.
Durch den Einsatz von hochwertigen Zementen sind diese Gemische mit erheblichen Kosten verbunden. Die Kosten werden durch den Einsatz von Schaumgläsern, die bei sehr hohen Temperaturen gebläht und hergestellt werden, weiterhin erhöht.By using high-quality cements, these mixtures are associated with considerable costs. The costs are further increased by the use of foam glasses, which are blown and manufactured at very high temperatures.
Der Erfindung liegt die Aufgabe zugrunde, leichte und stabile Bauteile und/oder Gemische herzustellen, die vielseitig für den Innen- und Außenausbau verwendbar sind, nahezu ausschließlich aus Reststoffen bestehen und kostengünstig produzierbar sind. Dies wird erfindungsgemäß dadurch erreicht, daß dieses Bindemittel mit an sich bekannten Schaumbildnern oder mit aus recycelten Altglas geschäumten Granulaten oder ähnlichen porösen Materialien und Wasser vermischt, ggf. anschließend in Formen verpreßt und zur Aushärtung gebracht wird.The invention has for its object to produce light and stable components and / or mixtures that can be used in a variety of ways for interior and exterior construction, consist almost exclusively of residues and can be produced inexpensively. This is achieved in accordance with the invention in that this binder is mixed with known foam formers or with granules or similar porous materials and water foamed from recycled waste glass, if necessary subsequently pressed into molds and brought to hardening.
Als Verbrennungsrückstände kommen Braunkohlen-, Steinkohlen-, Wirbelschichtfilteraschen in Betracht. Die wasserhaltigen Substanzen können Wasser bzw. kristallwasserhaltige Flüssigkeiten bzw. Stoffe und teilentwässertes Gips-Dihydrat sein.Lignite, hard coal, fluidized bed filter ash can be considered as combustion residues. The water-containing substances can be water or liquids or substances containing water of crystallization and partially dewatered gypsum dihydrate.
Als Schaumbildner bzw. Treibmittel können alle chemischen Stoffe und Verbindungen, die durch eine chemische und/oder physikalische Reaktion einen Blähoder Schäumungsvorgang auslösen, verwendet werden.All chemical substances and compounds which trigger a blowing or foaming process through a chemical and / or physical reaction can be used as foaming agents or blowing agents.
Der Schaumbildner wird in einer Menge von 0,3 - 3 M-%, bezogen auf das Gesamtgemisch, verwendet. Der Anteil des Bindemittelleims beträgt zwischen 5 - 60 M-%, je nach Verwendungszweck des Produkts, wobei eine stark wärmedämmende Verwendung bei untergeordneter Tragfähigkeit im unteren Bereich und eine weniger wärmedämmende Verwendung bei erhöhter Tragfähigkeit im oberen Bereich angesiedelt ist. Der Schaumbildner wird dabei zuerst dem Wasser oder gleichzeitig mit diesem dem Mischer zugegeben. Zur Erzeugung der notwendigen Luftporenmenge ist eine erhöhte Mischzeit (mindestens 120 Sekunden) erforderlich.The foaming agent is used in an amount of 0.3-3% by mass, based on the total mixture. The proportion of binder glue is between 5 - 60 M%, depending on the intended use of the product, with a strong heat-insulating use with subordinate load-bearing capacity in the lower area and a less heat-insulating use with increased load-bearing capacity in the upper area. The foaming agent is first added to the water or simultaneously to the mixer. An increased mixing time (at least 120 seconds) is required to generate the necessary amount of air pores.
Überraschenderweise hat sich herausgestellt, daß ein in der beschriebenen Art und Weise hergestelltes Gemisch ohne spezielle Luftzufuhr oder besondere Behandlung unter Lufterhärtung ein Produkt ergibt, aus welchem Betone, Platten, Steine etc. herstellbar sind, die teilweise gute bis sehr gute Wärmedämmwerte bei ausreichenden Trageigenschaften erzielen.Surprisingly, it has been found that a mixture produced in the manner described without special air supply or special treatment with air hardening results in a product from which concretes, slabs, stones, etc. can be produced, some of which achieve good to very good thermal insulation values with sufficient wearing properties .
Beim Einsatz von Granulaten kommen alle aus unsortiertem Altglas herzustellenden Schaumgläser oder dgl. zur Anwendung.When using granules, all foam glasses or the like to be produced from unsorted waste glass are used.
Das Bindemittel wird in diesem Fall mit einem Anteil von 20 - 95 Vol-%, vor- zugsweise 50 - 80 Vol-% Schaumglasgranulat und 80 - 5 Vol-%, vorzugsweise 50 - 20 Vol-% Bindemittel hergestellt. Besonders vorteilhaft ist, daß das verwendete Bindemittel durch seine spezielle Verweildauer und abgestufte Temperaturbehandlung bereits bei der Herstellung auf den Anwendungszweck konkret vorbehandelt werden kann, so daß das Bindemittel und das geschäumte Granulat immer optimal aufeinander und auf den Verwendungszweck angepaßt wird. Kostenmäßig ergibt die Kombination von dem verwendeten komplett aus Reststoffen herzustellenden Bindemittel mit dem wiederum ausschließlich aus Recyclingstoffen herzustellenden geschäumten Granulaten eine nahezu ideale Verbindung. Dies um so mehr, da nur Granulate verwendet werden, die ohne Hochtemperaturbehandlung gebläht und hergestellt werden.In this case, the binder is produced with a proportion of 20-95% by volume, preferably 50-80% by volume of foam glass granulate and 80-5% by volume, preferably 50-20% by volume, of binder. It is particularly advantageous that the binder used can be pretreated specifically for the intended use during manufacture, due to its special residence time and graduated temperature treatment, so that the binder and the foamed granulate are always optimally matched to one another and to the intended use. In terms of cost, the combination of the binder used, which is to be produced entirely from residual materials, with the foamed granules, which in turn can be produced exclusively from recycled materials, results in an almost ideal connection. This is all the more so since only granules are used that are blown and manufactured without high-temperature treatment.
Überraschenderweise hat sich bei der Vermischung des speziellen Bindemittels mit porösen Materialien, insbesondere mit Schaumgläsern, gezeigt, daß aufgrund von unerwartet hohen Oberflächenkräften eine besonders gute Haftver- bundwirkung auftritt. Dies macht es möglich, verminderte Mengen Bindemittelleim einzusetzen und dennoch neben der guten Dämmwirkung eine nennbare Stabilität zu erreichen, die auf einer verstärkten Druckfestigkeit beruht.Surprisingly, it has been found in the mixing of the special binder with porous materials, in particular with foam glasses, that a particularly good adhesive bond effect occurs due to unexpectedly high surface forces. This makes it possible to use reduced amounts of binder glue and, in addition to the good insulation effect, to achieve noticeable stability based on increased pressure resistance.
Anhand zweiter Ausführungsbeispiele soll nachstehend die Erfindung näher erläutert werden.The invention will be explained in more detail below with the aid of second exemplary embodiments.
Beispiel 1example 1
Hergestellt werden sollen geschäumte Bauelemente für Wärmedämmwände.Foamed components for thermal insulation walls are to be manufactured.
Dafür werden 125 kg spezielles Bindemittel mit 56,3 Liter Wasser in einem Zwangsmischer mindestens 3 Minuten intensiv gemischt. Gleichzeitig mit dem Anmachwasser werden 1 ,7 I eines flüssigen Schaumbildners in den Mischer gegeben.For this, 125 kg of special binder are mixed intensively with 56.3 liters of water in a compulsory mixer for at least 3 minutes. At the same time as the mixing water, 1.7 liters of a liquid foaming agent are added to the mixer.
Das Gemisch wird nach dem Mischvorgang in geeignete Formen gegeben, die der gewünschten Produktgröße entspricht, z. B. in Quaderformen 12 x 30 x 60 cm. Nach etwa 2 Stunden werden die Baukörper entschalt und bis zum Einbau trocken gelagert. An gleichzeitig von diesem Gemisch hergestellten Prüfprismen entsprechend DIN EN 196 können folgende charakteristische Kennwerte ermittelt werden:After the mixing process, the mixture is placed in suitable molds which correspond to the desired product size, e.g. B. in rectangular shapes 12 x 30 x 60 cm. After about 2 hours, the structures are removed and stored dry until they are installed. The following characteristic values can be determined on test prisms simultaneously produced from this mixture in accordance with DIN EN 196:
Festkörperdichte: 0,625 g/cm3 Druckfestigkeit nach 28 Tagen: 2,85 N/mm2 Solid density: 0.625 g / cm 3 compressive strength after 28 days: 2.85 N / mm 2
Beispiel 2Example 2
Für die Herstellung von Steinen, Platten oder dgl., die zur Erstellung von wär- medämmenden Innen- und Außenwänden eingesetzt werden, werden 75 kg speziellen Bindemittels in einem Zwangsmischer zunächst mit 38 I Wasser intensiv gemischt (> 1 ,5 Minuten). In dem so hergestellten Bindemittelleim werden 22 kg Schaumglasgranulat gegeben und das Gemisch nochmals so lange vermengt, bis alle Schaumglaspartikel mit Suspension vollständig umhüllt sind. Sodann wird das fertige Gemisch in Formen abgefüllt und unter natürlichen Bedingungen erhärtet.For the production of stones, slabs or the like, which are used to create heat-insulating interior and exterior walls, 75 kg of special binding agent are first mixed intensively with 38 liters of water in a compulsory mixer (> 1.5 minutes). 22 kg of foam glass granulate are added to the binder glue produced in this way and the mixture is mixed again until all foam glass particles are completely coated with suspension. The finished mixture is then filled into molds and hardened under natural conditions.
An gleichzeitig mit dem Herstellungsprozeß von diesem Gemisch hergestellten Prüfprismen entsprechend DIN EN 196 können folgende charakteristische Kennwerte ermittelt werden:The following characteristic values can be determined on test prisms according to DIN EN 196 that are produced simultaneously with the production process of this mixture:
Festkörperdichte: 0,585 g/cm3 Solid density: 0.585 g / cm 3
Druckfestigkeit nach 28 Tagen: 10,48 N/mm2 Compressive strength after 28 days: 10.48 N / mm 2
Je nach Verwendungszweck werden entweder entsprechend den Bauvorschrif- ten abgestimmte Sieblinien von Granulat oder auch nur ausgewählte spezielle Fraktionen zum Einsatz kommen. Depending on the intended use, either sieve lines of granulate that are coordinated in accordance with the building regulations or only selected special fractions will be used.
