Description

Werkstoff Zusatz zum Patent 942 351 Wird .ein Bentonitgel mit Bentonitteilchen, die vorzugsweise kleiner als 3ooo° A sind, eingetrocknet, so wird ein papierähnliches Gebilde erhalten. Dieses Gebilde hat aber nur geringe Festigkeit und ist nur wenig biegsam. Gegen Wasser ist es empfindlich, da es darin quillt.Material addition to patent 942 351 If. A bentonite gel with bentonite particles, which are preferably less than 3,000 ° A, dried, so a paper-like Preserved structure. However, this structure has only little strength and is only little flexible. It is sensitive to water because it swells in it.

Gemäß Patent 942 751 wird die Festigkeit und Biegsamkeit durch Einverleibung von Glasfasern erhöht. Durch die Erfindung wird eine weitere Steigerung der Festigkeit, Biegsamkeit und anderer physikalischer Eigenschaften erreicht. Dazu wird zur Aufschlämmung der feinen Bentonitteilchen ein Alkohol, wie z. B. d:enatttrierter Äthylalkohol, vorzugsweise in Mengen von etwa 5o%- gegeben, der Amine löst. Dann wird in der alkoholischen Lösung ein Amin, wie Diamylamin, Triäthylentetramin oder Äthylendiamin gelöst. Die Meng° des zugesetzten Amins hängt von den angestrebten Eigenschaften des Endproduktes ab. Soll nur die Biegsamkeit erhöht werden, so genügt ein Zusatz von i '/o", berechnet auf die Gesamtfestsubstanz. Soll das Endprodukt dagegen wasserfest se-in, braucht man io bis 20 Gewichtsprozent Amin.According to Patent 942,751 the strength and flexibility is increased by incorporation of glass fibers. The invention achieves a further increase in strength, flexibility and other physical properties. For this purpose, an alcohol, such as, for. B. d: enatttrierter ethyl alcohol, preferably in amounts of about 5o% - given, which dissolves amines. Then an amine such as diamylamine, triethylenetetramine or ethylenediamine is dissolved in the alcoholic solution. The amount of amine added depends on the desired properties of the end product. If only the flexibility is to be increased, an addition of i '/ o "is sufficient, calculated on the total solid substance. If, on the other hand, the end product is to be waterproof, 10 to 20 percent by weight of amine is required.

Die gemäß der Erfindung erhaltenen papierähnlichen Gebilde können nicht nur - wie die nach dem Hauptpatent - mit ,eingelagerten Glasfasern verwendet werden, sondern auch ohne solche Einlagerung. Ein Blatt von 51 bis 76,u Dicke hat ohne Glasfasern eine Festigkeit von etwa 25o kglcm2 und eine Durchschlagsfestigkeit von i2o bis 16o Volt pro Millimeter. Dde Biegefestigkeit des neuen. Werkstoffs ist sehr hoch, so daß auch ein Glasfasern enthaltendes Blatt gefaltet werden kann, ohne zu zerbriechen.The paper-like structures obtained according to the invention can not only - like the one according to the main patent - used with embedded glass fibers but also without such storage. Has a sheet of 51 to 76, u thickness Without glass fibers a strength of about 25o kg / cm2 and a dielectric strength from i2o to 16o volts per millimeter. Dde flexural strength of the new. Material is very high, so that even a sheet containing glass fibers can be folded without to shatter.
