Description
Verfahren zur Herstellung von Dämmstoffen und dämmenden Bauteilen bzw. Bauelementen Die Erfindung betrifft ein Verfahren zur Herstellung von Dämmstoffen und dämmenden Bauteilen, bzw. Bauelementen. Bauteile oder -konstruktionen bestehen vielfach aus tragenden Schichten, auf und zwischen welchen die dämmenden Schichten als Platten, Matten oder in Schüttung angeordnet sind. Als Material finden z.B: Glas- oder Steinwolle, organische oder anorganische Kunststoffschäume, neuerdings auch Schaumglas, Verwendung. An diese Dämmstoffe ist die Forderung zu stellen, daß sie volumenkonstant sein müssen, d.h. sie dürfen nach Einbau ihre Form-nioht durch Quellen, Schrumpfen, Absacken, Zerstörung und dgl. verändern. Ferner muß der Wärmedurehgangswiderstand konstant bleiben. Dieser ist aber im wesentlichen von der Dampfdurahläsügkeit des Dämm-Stoffes abhängig. Ist nämlich der Dampfdurehgangswiderstand der dämmenden Schicht größer als der der tragenden Schicht, dann muß sich in der tragenden Schicht Feuchtigkeit niederschlagen, ebenso wie sich Feuchtigkeit in der dämmenden Schicht niederschlagen muB, wenn umgekehrt der Dampfdurehgangswiderstand in der tragenden größer ist. Die obengenannten Nachteile werden dadurch beseitigt, daß zur Her- stellung von Dämmstoffen und dämmenden Bauteilen, bzw. Bauelementen, erfindungsgemäß kornförmige thermisch behandelte mikroporöse mineralische Partikel in räumlichen Begrenzungen geschüttet und mittels organischer und/oder anorganischer Binderriittelleime oder Thermoplaste oder durch Sintern miteinander punktförmig verbunden werden. Method for producing insulating materials and insulating components or components The invention relates to a method for producing insulating materials and insulating components or components. Components or constructions often consist of load-bearing layers on and between which the insulating layers are arranged as panels, mats or in bulk. The following materials are used, for example: glass or rock wool, organic or inorganic plastic foams, and recently also foam glass. The requirement to be made of these insulation materials is that they must be of constant volume, ie they may not change their shape after installation due to swelling, shrinking, sagging, destruction and the like. Furthermore, the heat transfer resistance must remain constant. However, this is essentially dependent on the steam duration of the insulation material. If the vapor flow resistance of the insulating layer is greater than that of the load-bearing layer, then moisture must precipitate in the load-bearing layer, just as moisture must precipitate in the insulating layer if, conversely, the vapor flow resistance in the load-bearing layer is greater. The above disadvantages are eliminated by the manufacturing position of insulation materials and absorbing components, or components, are according to the invention granular thermally treated microporous mineral particles in space limitations poured in point-connected to each other by means of organic and / or inorganic Binderriittelleime or thermoplastics or by sintering .
Vorzugsweise werden hierbei Partikel etwa gleicher Größe verwendet.Particles of approximately the same size are preferably used here.
Es können.aueh Partikel unterschiedlicher Größe in Sieblinie Verwendung finden.It is also possible to use particles of different sizes in the grading curve Find.
Es ist zweckmäßig, bei Verwendung eines Bindemittelleimes diesem z.B. 0,1 - 7 Vol.-% hoehdisperse Kieselsäure zuzusetzen.When using a binder glue, it is expedient to use this e.g. Add 0.1-7% by volume of highly disperse silica.
Während des Abbindevorgangs kann der Sehüttung Luft oder Warmluft von unten zugeführt werden.During the setting process, the Sehüttung can air or warm air fed from below.
Nach einer weiteren Durchführungsart des Verfahrenswerden anschließend oder gleichzeitig auf die Dämmstoffe, dämmende Bauteile, bzw. Bauelemente, einseitig oder beiderseitig Verkleidungen oder Beschichtungen aufgebracht.After another way of carrying out the procedure, or at the same time on the insulating materials, insulating components or construction elements, one-sided or cladding or coatings applied on both sides.
Die Dämme toffe, dämmenden Bauteile, bzw. Bauelemente können auch mit tragenden Bauteilen bzw. Bauelementen verbunden werden. Zweckmäßigerweise werden zur Verbindung der Dämmstoffe, dämmenden Bauteile,-bzw. Bauelemente mit den Beschichtungs- bzw. Verkleidungsanlagen, und/oder den tragenden Bauteilen, bew. Bauelementen organische und/oder anorganische Bindemittel Verwendet. The insulating materials, insulating components or components can also be connected to load-bearing components or components . Appropriately, to connect the insulating materials, insulating components, -bzw. Components with the coating or cladding systems, and / or the load-bearing components, moving components, organic and / or inorganic binders are used.
Die Erfindung wird anhand der Zeichnung näher erläutert. Es zeigt: Fig. 1 einen Bauteil mit einer, aus kornförmigen Partikeln be- stehenden Dämmehioht im Schnitt; Fig.2 einen Bauteil mit einer aus kornförmigen, dicht in einem Binder eingebetteten Partikeln i bestehenden Dämmschicht im Schnitt zum Vergleich; Fig. 3 in eine Form eingebrachte Dämmpartikel mit von unten zu-_ geführter Luft im Schnitt; Fig. 4 die Struktur eines Bauelementes im Ausschnitt vergrößert. Am Bauteil 11 ist die Dämmschicht 12 angelagert, die die Partikel 13 und die dazwischen liegenden Haufwerksporen 14 aufweist. Die mikroporösen mineralischen Partikel 13 sind an sich dampfundurchlässig, doch kann der Dampf - wie in Fig. 1 durch die Pfeillinie A gezeigt - die Dämmschicht 12 aufgrund der Haufwerksporen 14 in jeder Richtung durchdringen. The invention is explained in more detail with reference to the drawing. It shows: Figure 1 shows a component with one made of granular particles sawn stationary Dämmehioht in section;. 2 shows a component with an insulating layer consisting of granular, densely embedded particles i in a binder, in section for comparison; 3 shows insulation particles introduced into a mold with air supplied from below, in section; 4 shows an enlarged detail of the structure of a component. The insulating layer 12, which has the particles 13 and the pores 14 lying between them, is deposited on the component 11. The microporous mineral particles 13 are impermeable to vapor per se, but the vapor - as shown in FIG. 1 by the arrow line A - can penetrate the insulation layer 12 in any direction due to the pile pores 14.
Die Partikel können aus beliebigen Mineralien mit entsprechender Wärmeleitzahl
bestehen, beispielsweise aus Silikaten, Oxyden oder anderen Mineralien mit möglichst
großem Kristallwassergehalt, die ggf. unter Zusatz von Treibmitteln mit nachfolgender
thermischer Behandlung zu kornförmigen Partikeln geformt werden. Die thermische
Behandlung kann in einem Schmelzvorgang bestehen (z.B. bei Schaumglas) oder in einem
Sintern bzw. Brennen (z.B. bei keramischen Werkstoffen).
Die Dehnbarkeit der Bindemittel soll jedoch begrenzt sein, um die Zugbeanspruchung nicht auf den Beschiehtungsstoff zu begrenzen, sondern sie kontinuierlich von der Randzone bis zur statischen Nullinie abzubauen und um die aufwendigen, nur zugbeanspruchten, Bindemittel zu streeken. Da bekanntlich hydraulische Bindemittel wie Zement oder Kalk mit üblichen Kuns tharzdispersionen wie Polyvinylacetat, nur dann verträglich sind, wenn die fertige Mischung nicht Wasser oder Dampfausgesetzt wird, kann hier eine solche Einmischung ohne weiteres deshalb erfolgen, weil eine genügende Entlüftung durch die Haufwerksporen erfolgt, In entsprechender Weise ist es möglich, dämmende und tragende Elemente miteinander zu verbinden und ggf. zusätzlich mit einer Beschichtung oder Verkleidung zu versehen, Nach dem erfindungsgemäßen Verfahren lassen sich beliebige Bauelemente wie Platten, Träger, Stein und dergl, herstellen.However, the extensibility of the binders should be limited in order not to limit the tensile stress to the coating material, but to reduce it continuously from the edge zone to the static zero line and to stretch the complex binders that are only subjected to tensile stress. Since it is well known that hydraulic binders such as cement or lime are only compatible with conventional synthetic resin dispersions such as polyvinyl acetate if the finished mixture is not exposed to water or steam, such mixing can easily take place here because there is sufficient ventilation through the pore pores, In In a corresponding manner, it is possible to connect insulating and load-bearing elements with one another and, if necessary, additionally provide them with a coating or cladding. Using the method according to the invention, any desired structural elements such as panels, beams, stone and the like can be produced.
