Description
Verfahren zum Herstellen von Wärmedämmmassen Die Erfindung betrifft ein Verfahren zum Herstellen von Wärmedämmassen aus Blähstoffen, wie Blähglimmer, Blähobsidian, Bims, Kork, Blähkunststoff od. dgl., und einem Bindemittel, und das Neue besteht darin, daß als Bindemittel zwei oder mehr Stoffe, wie Bitumen, Asphalt, Teer, Pech, Öl, Thermoplastikstoffe od. dgl., verwendet werden, deren Zonen plastischer Verforinbarkeit ohne Unterbrechun ineinander übergehen, so, daß eine Gesamterweichungszone gebildet wird, die sich über einen größeren Temperaturbereich erstreckt als die - Erweichungszone jedes einzelnen Bestandteiles für sich allein. Bei solchen Wärmedämmstoffen hat -sich der übelstand ergeben, daß bei der großen Neigung dieser Stoffe zum Aufnehmen von Feuchtigkeit diese hernach oftmals nicht voll wieder abgeschieden wird. Um die Aufnahme von Feuchtigkeit zu verhindern oder mindestens zu beschränken, wird vielfach eine wasserabweis,ende Zugabe hinzugefügt, welche die Körner des Blähstoffes oder sonstigen Wärmedämmungsmittel umhüllt und dadurch die Feuchtigkeit von ihnen abhält.Method for producing thermal insulation compounds The invention relates to a method for producing thermal insulation compounds from expandable materials such as expanded mica, expanded obsidian, pumice, cork, expanded plastic or the like, and a binding agent, and what is new is that two or more substances are used as binding agents, Such as bitumen, asphalt, tar, pitch, oil, thermoplastic materials or the like, are used, whose zones of plastic deformability merge into one another without interruption, so that a total softening zone is formed which extends over a larger temperature range than the - softening zone of each individual Component on its own. In the case of such thermal insulation materials, the problem has arisen that, given the great tendency of these materials to absorb moisture, it is often not fully separated again afterwards. In order to prevent or at least limit the absorption of moisture, a water-repellent addition is often added, which envelops the grains of the expanding material or other thermal insulation material and thereby keeps the moisture away from them.
Gemäß der Erfindung wird nun diese Zugabe von umhüllenden und bindenden Stoffen aus verschiedenen solchen derart zusammengesetzt, daß die Zonen, in denen sie teigige Beschaffenheit annehmen, ineinander übergreifen. Diese teigigen Zonen werden durch die Temperaturabschnitte bestimmt-, in denen die einzelnen Mittel dickflüssig sind; eine solche Zone reicht also von ihrem unteren kalten Ende, bei dem der Stoff aufhört starr zu sein, bis zum oberen warmen Ende, bei dem seine Verflüssigung beginnt. Innerhalb dieser Temperaturzone schrniegt sich der Stoff an die zu umhüllenden Körner des Dämmstoffes an; unterhalb der Zonengrenze erfolgt dies nicht, oberhalb der Obergrenze aber läuft das Mittel von den Körnern ab. Im Betrieb treten nun an verschiedenen Stellen der Wärmedämmschicht sehr unterschiedliche Temperaturen auf, nahe der Außenluft niedrige, dicht an dem zu schützenden Innengegenstand aber reichlich hohe. Hierzu kommt, daß in Betriebspausen oft' eine weitgehende Abkühlung erfolgt, und hernach bei Wiederinbetriebnahme eine oft sprunghafte und an den einzelnen Stellen verschiedene Erhitzung. Dann läuft längs solcher besonders heißen Stellen das umhüllende Bindemittel ganz ab und bildet an den noch kalten Punkten mit dem noch starren Bindemittel Klumpen, welche die Wärmedämmwirkung beeinträchtigen.According to the invention, this addition of enveloping and binding Substances composed of various such in such a way that the zones in which they take on a doughy texture, overlap each other. Those doughy zones are determined by the temperature sections in which the individual agents are viscous are; such a zone extends from its lower cold end, at which the substance ceases to be rigid, up to the upper warm end, at which it begins to liquefy. Within this temperature zone, the substance clings to the grains to be coated of the insulation material; this does not take place below the zone limit, above the upper limit but the remedy runs off the grains. In operation now occur at various Set the thermal insulation layer to very different temperatures, close to the outside air low, close to the interior object to be protected, but abundantly high. For this comes that during breaks in operation there is often 'extensive cooling, and afterwards when the system is restarted, it is often erratic and different at the individual points Heating. The enveloping binder then runs along such particularly hot spots completely and forms lumps at the still cold points with the still rigid binding agent, which impair the thermal insulation effect.
Besteht nun das Umhüllmittel erfindungsgemäß aus mehreren Stoffen mit verschiedenen Erweichungsbereichen, so trifft das eine sich bereits verflüssigende Mittel auf Teile des noch erst teigigen, so daß es von diesem aufgehalten wird. Dadurch wird sein völliges Niederfließen und jede Klumpenbildung verhindert. Es entsteht hier eine Teigmasse, welche ihre sämtlichen Bestandteile an dieser Stelle festhält, die Entmischung der einzelnen Bestandteile wird unterbunden.If, according to the invention, the wrapping means consists of several substances with different softening areas, the one that is already liquefying meets Means on parts of the still doughy so that it is held up by this. This prevents it from flowing down completely and any lump formation. It A dough mass is created here, all of its components at this point holds, the segregation of the individual components is prevented.
An sich ist es bekannt, ein solches Umhüllmittel aus verschiedenen Bestandteilen zusammenzusetzen. So sind in der deutschen Patentschrift 887 768 für diesen Zweck Emulsionen von Bitumen oder Asphalt, auch Silikatkleber aus Wasserglas mit Aluminiumacetat und gegebenenfalls Metallfluoriden angegeben, wobei die Wärmedämmstoffe selbst organischer Art unterstellt sind. Daraus ist für den fachmännischen Leser dieser Druckschrift keinerlei Hinweis gegeben, daß diese Umhüllmittel sich mit ihren Erweichungsbereichen in der vom Erfinder gelehrten Weise aneinanderfügen sollen, und vorgenommene Untersuchungen haben für verschiedene Kombinationen davon ergeben, daß dies nicht der Fall ist. Es ist demnach in dieser Schriftstelle nicht die erfindungsmäßige Lehre gegeben.It is known per se to assemble such an encasing agent from various components. Thus, in German patent specification 887 768, emulsions of bitumen or asphalt, including silicate adhesives made of water glass with aluminum acetate and optionally metal fluorides, are given for this purpose, the thermal insulation materials themselves being assumed to be organic. From this there is no indication for the skilled reader of this publication that these envelopes should join together with their softening areas in the manner taught by the inventor, and investigations carried out have shown for various combinations thereof that this is not the case. The teaching according to the invention is therefore not given in this passage.
Auch in der Patentschrift 321029 ist ein aus mehreren Bestandteilen zusammengesetztes Umhüllmittel angegeben, aber auch aus dieser Schriftstelle ist der Erfindungsgedanke nicht zu entnehmen, denn es soll neben einem gar nicht zu teigiger Beschaffenheit zu bringenden Stoff, wie Kalk oder Zement, noch Paraffin verwendet werden, um dadurch dem ganzen eine Säurefestigkeit zu geben.Patent 321029 also specifies a coating made up of several components, but the idea of the invention cannot be inferred from this reference either, because paraffin should be used in addition to a substance that is not too doughy, such as lime or cement, in order to give the whole thing an acid resistance.
Auf einem ganz anderen Fachgebiet, der Herstellung von Faserstoffen und Faservließen, ist an sich eine große Reihe von zuzusetzenden Mitteln bekannt, aber eine Auswahl aus ihnen zu nehmen, um das Ziel der Erfindung zu erreichen, wird damit dem Fachmann in keiner Weise gelehrt. Erst gemäß der Erfindung wird der Vorschlag gemacht, die Bindemittelteile auf ihre Erweichungszonen anzusehen und danach zu wählen. Nach der weiteren Ausbildung des Verfahrens wird ferner vorgeschlagen, daß bei der Verarbeitung die Bindemittel bei verschiedenen Temperaturen, vorzugsweise bei ihren einzelnen Erweichungstemperaturen, aufzugeben sind, daß einige von ihnen oder alle vor ihrer Zugabe vermischt oder verrührt werden sollen und daß außerdem Stoffe, wie Kalk, Zement oder Ton, also nicht die Eigenschaften der eigentlichen Binde- oder Umhüllmittel aufweisende Werkstoffe zugesetzt werden können.In a completely different field, the manufacture of fiber and fiber fleeces, a large number of agents to be added are known per se, but making a selection from them in order to achieve the aim of the invention will thus in no way taught to those skilled in the art. Only according to the invention is the proposal made the binder parts to look at their softening zones and then to choose. After the further development of the procedure, it is also proposed that that when processing the binders at different temperatures, preferably at their individual softening temperatures, some of them are to be abandoned or all of them are to be mixed or stirred before their addition, and that in addition Substances such as lime, cement or clay, not the properties of the actual ones Binding or wrapping materials having materials can be added.
Aus den erfindungsgemäß gewonnenen Massen können vorteilhaft auch Platten, Rohre und andere Forinstücke durch Pressen, Stampfen, Walzen in an sich bekannter Weise hergestellt werden.From the masses obtained according to the invention can also advantageously Plates, pipes and other shaped pieces by pressing, ramming, rolling in per se be produced in a known manner.
