Description

Verfahren zur rstellungivon porösen Baumaterialien. Zusatz zum Patent 421777. Durch Patent 42 1 777 ist ein Verfahren zur Herstellung von porösen Baumaterialien aus mit Wasser zu mischenden Mineralstoffen durch Hinzufügung von auf mechanischem Wege hergestelltem Schaum zu dem Mörtelbrei geschützt.Process for making porous building materials. Addendum to patent 421 777. Patent 42 1777 protects a process for the production of porous building materials from mineral substances to be mixed with water by adding mechanically produced foam to the mortar slurry.

Andererseits ist es bekannt, poröse Baumaterialien auf die Art herzustellen, daß gasentwickelnde Stoffe der Grundmasse zugesetzt werden und die dadurch entstehenden Gasbläschen in der erstarrenden Masse festgehalten werden.On the other hand, it is known to manufacture porous building materials in the manner that gas-evolving substances are added to the base mass and the resulting Gas bubbles are held in the solidifying mass.

Die vorliegende Erfindung betrifft nun ein Verfahren zur Herstellung von Schaum, der für das durch das obenerwähnte Patent geschützte Verfahren angewendet werden kann, indem dieser fertig gebildete Schaum der Grundmasse zugesetzt wird - und dadurch poröse Körper bildet.The present invention now relates to a method of manufacture of foam used for the process protected by the above-mentioned patent can be by adding this ready-formed foam to the base material - and thereby forms porous bodies.

Es hat sich durch Versuche erwiesen, daß es möglich ist, den Schaum auf die Art herzustellen, daß man zu der Lösung eines geeigneten Stoffes, die eine mechanische Schaumbildung gestattet, eine gasentwickelnde Substanz hinzufügt, z. B. Calciumcarbid zu einer wäßrigen Lösung von Pflanzenschleim oder Aluminiumpulver zu einer alkalischen Seifenlösung.Experiments have shown that it is possible to use the foam in such a way that one leads to the solution of a suitable substance which has a mechanical foaming allows a gas evolving substance to be added, e.g. B. calcium carbide to an aqueous solution of plant slime or aluminum powder to an alkaline soap solution.

Der auf diese Art gebildete Schaum wird danach in den Mörtelbrei gemischt.The foam formed in this way is then mixed into the mortar slurry.

PATENTANSPRUCH: Verfahren zur Herstellung' von porösen Baumaterialien nach Patent 421 777, dadurch gekennzeichnet, daß anstatt des auf mechanischem Wege gewonnenen Schaumes solcher verwendet wird, der durch Gasentwicklung auf chemischem Wege für sich hergestellt wurde. PATENT CLAIM: Process for the production of porous building materials according to patent 421 777, characterized in that, instead of the foam obtained by mechanical means, foam is used which was produced by chemical means by gas evolution.
