EMI1.1
EMI1.2
Mischung mehrerer dieser Stoffe.
Diese Stoffe werden, wenn erforderlich und falls sie nicht wie die Asbestfasern unverbrennbar sind, durch Hinzufügen von Alaun, Borax oder dgl. unverbrennbar gemacht.
Die Asbestfasern besitzen den Nachteil, dass bei ihrer Anwendung in grösserer Menge das Isoliervermögen der'Masse stark beeinträchtigt wird. Ebenso verhalten sich Kork und Sägespane.
Lehm, Talk und Gips erhalten wärmeleitende Eigenschaften, wenn sie trocken sind.
Die vorliegende Erfindung bezweckt nun die Herstellung einer Isoliermasse, welche ein grösseres wärmeisolierendes Vermögen besitzt als die bisher benutzten Stoffe.
Es hat sich gezeigt, dass bei Verwendung von Holzpapier oder Holzbrei in einem Lt'stimmten Verhältnis zu Kieselgurkomposition-wie sie im Handel erhältlich ist tworanter ein Gemenge von Kieselgur Pfeifenton, Kreide und Dextrin verstanden wird)- und von Alaun, feiner Kreide und Sägemehl oder ähnlichem FUllstoss eine Isoliermasse erhalten wird, welche sich durch ein besonders hohes Isoliervermögen auszeichnet und durch Hinzufügen einer geringen Menge Harz ein so grosses Anhaftungsvermögen an die Unterlage erhält, dass das so hergestellte Isoliermittel alle bisher bekannten in dieser
Beziehrungübertrifft.
Den bisher bekannten Isoliermitteln gegenüber verdankt die Isoliermasse nach vor-
EMI1.3
passendet) Wahl der miteinander zu vermischenden Stoffe, sondern eine sehr wichtige Rolle spielt das perzentuelle Verhältnis der Stoffe.
Das hohe Wärmeisolationsvermögen dieser Isoliermasse ist auf die grosse Menge von mit Luft ausgefüllten Räumen, welche sich im Innern der Masse befinden und welche bot keinem anderen Isolierstoff in so grosser Anzahl zu finden sind, zurückzuführen.
Ein weiterer technischer Effekt besteht darin, dass die Masse ein sehr geringes Gewicht aufweist.

zielen wie mit anderen Massen.
Gute Resultate erhält man bei folgenden Mischungsvcrhältnissen der einzelnen Stoffe :
EMI2.2
72 Gewichtsteile und Dextrin 1 Gewichtsteil)" n 10 Alaun, 1 a Kreide und # 5 # 25 # Sägemehl oder eines anderen Füllstoffes.
Insbesondere gibt das nachstehende Rezept eine sehr brauchbare Masse :
36 Gewichtsteile Ilolpapier, 1 far 18 # Kieselgurkomposition (wie im Handel erbältlich), J 8,. Alaun, Kreide und
EMI2.3
Soll die Masse für höhere Temperaturen bis zu 4000 Verwendung finden, so muss die Menge der zugesetzten Kieselgurkomposition erhöht werden.
Zur Herstellung der Masse wird das Holzpapier und das Harz in einer Schlagmühle oder in eincr iihtllichen Maschine sehr fein vermahlen ; die anderen Stoffe werden in

mahlene Holzpapier nter gleichzeitiger Besprengung mit Wasser diesen Stoffen in der Mischmühlezugesetzt.

EMI1.1
EMI1.2
Mixture of several of these substances.
If necessary and if they are not incombustible like the asbestos fibers, these substances are made incombustible by adding alum, borax or the like.
The asbestos fibers have the disadvantage that when they are used in large quantities, the insulating capacity of the mass is severely impaired. Cork and sawdust behave in the same way.
Clay, talc and gypsum acquire heat-conducting properties when they are dry.
The present invention now aims to produce an insulating compound which has a greater heat-insulating capacity than the substances previously used.
It has been shown that when using wood paper or wood pulp in a correct ratio to diatomaceous earth - as it is commercially available, a mixture of diatomaceous earth, pipe clay, chalk and dextrin is understood) - and of alum, fine chalk and sawdust or A similar filling an insulating compound is obtained, which is characterized by a particularly high insulating capacity and, by adding a small amount of resin, is given such a high degree of adhesion to the substrate that the insulating agent produced in this way is all previously known in this
Relationship surpasses.
Compared to the previously known isolating agents, the isolating compound owes
EMI1.3
suitable) choice of substances to be mixed with each other, but the percentage ratio of the substances plays a very important role.
The high thermal insulation capacity of this insulating compound is due to the large number of air-filled spaces which are located inside the compound and which cannot be found in such large numbers by any other insulating material.
Another technical effect is that the mass has a very low weight.

Good results are obtained with the following mixing ratios of the individual substances:

72 parts by weight and dextrin 1 part by weight) "n 10 alum, 1 a chalk and # 5 # 25 # sawdust or another filler.
In particular, the recipe below gives a very useful mass:
36 parts by weight of Ilol paper, 1 for 18 # kieselguhr composition (as commercially available), J 8 ,. Alum, chalk and
EMI2.3
If the mass is to be used for higher temperatures of up to 4000, the amount of the added kieselguhr composition must be increased.
To produce the mass, the wood paper and the resin are ground very finely in a hammer mill or in a single machine; the other substances are in

Grinded wood paper with simultaneous sprinkling with water added to these substances in the mixing mill.
