Description
Zusatzmittel für Hörtelbildner und lllörtel. Gegenstand der Erfindung ist ein Zu satzmittel für Mörtelbildner und Mörtel, um diese gegen Angriffsmittel beständig zu ma chen und einen Durchtritt von Wasser zu verhindern. Das Mittel ist dadurch gekenn zeichnet, dass es aus einem Ma.gnesiumver- bindungen enthaltenden Gemisch, dessen Be standteile in kolloidaler Form vorliegen und welchem bei der Bereitung Wasserglas zu gesetzt worden ist, besteht.
Als Magnesiumverbindungen können die ver schiedenartigsten natürlichen oder auch künst lichen, Magnesium enthaltenden Stoffe be nutzt werden. In erster Linie kommen Mag nesiamineraIien, wie Asbest, Talkum, Mag nesit, Dolomit usw., in Frage.
Es empfiehlt sich, gleichzeitig für die Gegenwart einer Fluorverbindung in dem Zusatzmittel zu sorgen. Zum Beispiel kann es Magnesiumfluorverbindungen enthalten An Stelle einheitlicher, flusssaurer Magnesium verbindungen können auch Gemische von Fluorverbindungen und Magnesiumverbin- ,dungen in dem Zusatzmittel enthalten sein.
Beispielsweise kann man Magnesium silikofluorid mittelst eines Schutzkolloides oder sonstwie kolloidisieren und mit Was serglas (Kalium- oder Natriumsilikat oder beiden) vereinigen, oder man geht von Mag-.
nesiummineralien aus, die mit Fluorwasser- stoffsäure oder einer komplexen Fluorwasser- stoffsäure, etwa Kieselfluorwasserstoffsäure, oder einem Fluorid, zum Beispiel Alkali- fluorid, Caloium- oder Magnesiumfluorid oder Siliziumfluorid, zusammen einer kolloi- disierenden Behandlung unterworfen werden,
so dass die genannten Stoffe bezw. etwa ent stehenden Umsetzungsprodukte nach der Be handlung in kolloidalem Zustande vorliegen. Das Kolloidisieren kann durch inniges Ver- mahlen mit Wasserglas erfolgen.
Bei Benutzung von Fluoriden arbeitet man zweckmässig noch mit Säure. Man lässt zum Beispiel Calciumfluorid und Schwefel säure auf das Magnesiamineral einwirken. Erforderlichenfalls setzt man hernach dem Dichtungsmittel Baryt hinzu, um die Schwe- f elsäure in eine unschädliche Form überzu führen. Siliziumfluorid benutzt man vorteilhaft in der Weise, dass man das Magnesiamineral in Wasser suspendiert und Siliziumfluorid einleitet.
Durch Verreiben, Mahlen, gegebenenfalls mit Hilfe von Schutzkolloiden oder durch die letzte Massnahme allein lassen sich die Bestandteile der Zusatzmittel für sich oder alle gleichzeitig kolloidisieren.
Lösliche Stoffe können in gelöster Form, zweckmässig in Form konzentrierter Lösun gen, benutzt werden. Man kann auch nur mit beschränkten Wiengen Lösungsmittel ar beiten, so dass unmittelbar ein pastenartiges Produkt anfällt. Will man das Zusatzmittel in trockener Form haben, so wird entweder das Produkt getrocknet oder gänzlich ohne Lösungsmittel gearbeitet.
Ein Zusatz alkalisch reagierender Stoffe fördert die Kolloidisierung, -sowie die Romo- genisierung des Zusatzmittels. Insbesondere wird Kalkmilch bei der Herstellung ges Zu satzmittels verwendet. Beispielsweise wird aua Magnesiumverbindungen, Wasserglas, Kalkmilch und Flusssäure bezw. deren Sal zen eine kolloidale Masse hergestellt.
An Stelle der einfachen Fluorverbindungen kann auch mit komplexen Fluorverbindungen ge arbeitet werden, etwa mit Kieselfluorwasser- stoffsäure oder deren Salzen.
Zur Erhaltung des kolloidalen Zustandes kann dem Zusatzmittel, das nach irgend einer der vorgenannten Ausführungsformen her gestellt ist, auch Tetrachlorkohlenstoff zu gesetzt werden.
Vorteilhaft werden dem Zusatzmittel noch wasserabweisende Stoffe, indifferente oder mehr oder weniger hydraulische Stoffe hezw. mehrere Stoffe dieser Arten einver leibt, sei es dem fertigen Zusatzmittel oder bei seiner Herstellung in irgend einer Ver fahrensstufe. Als wasserabweisende Stoffe kommen Fette, Öle, Bitumen, Eiweissstoffe oder Eiweissabbauprodukte und dergleichen in Frage. Andere in Frage kommende Zu satzstoffe sind Kalkstein, Schlacke, Ziegel mehl usw.
Insbesondere werden färbende Stoffe bekannter Art verwendet, :die auf diese Weise weitgehend im Mörtel verteilt werden und gleichzeitig, wie die andern Zusatzstoffe, das V erbesserungsinittel zum Teil zu ersetzen vermögen. Der Zusatz der letztgenannten Stoffe bann zii jedem der nach oben bezeich neten Ausführungsruten hergestellten Zusatz mittel erfolgen.
Bei der Herstellung des Zusatzmittels arbeitet man vorteilhaft bei erhöhter Tem peratur, etwa bei<B>50</B> bis<B>70</B> " C. Im einzelnen hängt die anzuwendende Temperatur von den zu verarbeitenden Ausgangsstoffen ab. Aber auch ohne jegliclif> @C'ärmezufulir las sen sich die Zusatzmittel bereiten. Das neue :Mittel dient als hhat'l. für Mörtelbildner, insbf@sondere Zemente jeglicher Art, Mörtel, Beton, Kunststein usw.
Es kann als Paste oder fein gemahlen dem Mörtel zugesetzt werden, oder man ver mischt es vorher mit dem Mörtelbildner, etwa in der Weise, dass man das pastenartige oder trockene Zusatzmittel dem Mörtelbild ner bei seiner Feinrnahlung zusetzt. Dureli das Zusatzmittel erbalten die Mörtelerzeugte nisse die Fähigkeit, mit Sicherheit einen Durchtritt von Wasser zu verhindern. Gleich zeitig sind sie beständig gegen chemische An griffe.
Sie widerstehen der Einwirkung von Ammoniak, Raueligas, schwachen Säuren, zum Beispiel schwefliger Säure, salpeter sauren Salzen usw. Das Zusatzmittel lässt sich derart. gestalten, dass es unmittelbar ver- sa.ndfähig bezw. versandfertig ist. Es kann auch in den für den Versand bestimmten CTe- fä.ssen selbst hergestellt werden.
Additive for plastering agents and mortars. The invention relates to an additive for mortar formers and mortar to make them resistant to attack agents and to prevent the passage of water. The agent is characterized in that it consists of a mixture containing magnesium compounds, the constituents of which are in colloidal form and to which water glass was added during preparation.
The most varied of natural or artificial substances containing magnesium can be used as magnesium compounds. In the first place, magnesia minerals such as asbestos, talc, magnesite, dolomite, etc. come into question.
It is advisable to ensure the presence of a fluorine compound in the additive at the same time. For example, it can contain magnesium fluorine compounds. Instead of uniform, hydrofluoric magnesium compounds, mixtures of fluorine compounds and magnesium compounds can also be contained in the additive.
For example, magnesium silicofluoride can be colloidized by means of a protective colloid or in some other way and combined with water glass (potassium or sodium silicate or both), or you can go from Mag-.
nesium minerals which are subjected to a colloidal treatment together with hydrofluoric acid or a complex hydrofluoric acid, such as silicofluoric acid, or a fluoride, for example alkali fluoride, calcium or magnesium fluoride or silicon fluoride,
so that the substances mentioned respectively. any resulting reaction products are in a colloidal state after the treatment. Colloidization can take place by intimate grinding with water glass.
When using fluorides it is advisable to work with acid. For example, calcium fluoride and sulfuric acid are allowed to act on the magnesium mineral. If necessary, barite is then added to the sealant in order to convert the sulfuric acid into a harmless form. Silicon fluoride is used advantageously in such a way that the magnesia mineral is suspended in water and silicon fluoride is introduced.
The constituents of the additives can be colloidized individually or all at the same time by rubbing, grinding, if necessary with the aid of protective colloids or by the last measure alone.
Soluble substances can be used in dissolved form, conveniently in the form of concentrated solutions. You can only work with limited Wiengen solvents, so that a paste-like product is obtained immediately. If you want to have the additive in dry form, either the product is dried or it is carried out entirely without a solvent.
The addition of substances with an alkaline reaction promotes colloidization and romogenization of the additive. In particular, milk of lime is used in the production of additives. For example, magnesium compounds, water glass, milk of lime and hydrofluoric acid are also used. their salts produce a colloidal mass.
Instead of the simple fluorine compounds, complex fluorine compounds can also be used, such as hydrofluoric acid or its salts.
To maintain the colloidal state, the additive, which is made according to any of the aforementioned embodiments, also carbon tetrachloride can be set.
Advantageously, water-repellent substances, indifferent or more or less hydraulic substances are added to the additive. several substances of these types are incorporated, be it the finished additive or its production in any process stage. Fats, oils, bitumen, protein substances or protein degradation products and the like can be used as water-repellent substances. Other possible additives are limestone, slag, brick flour, etc.
In particular, coloring substances of a known type are used: which are largely distributed in this way in the mortar and at the same time, like the other additives, are able to partially replace the improver. The last-mentioned substances can be added to each of the above-mentioned execution rods.
When producing the additive, it is advantageous to work at an elevated temperature, for example at <B> 50 </B> to <B> 70 </B> "C. In detail, the temperature to be used depends on the starting materials to be processed The additives can be prepared without any heat supply. The new: Agent serves as a hhat'l for mortar formers, especially special cements of any kind, mortar, concrete, artificial stone, etc.
It can be added to the mortar as a paste or finely ground, or it can be mixed beforehand with the mortar-forming agent, for example in such a way that the paste-like or dry additive is added to the mortar-forming agent during its fine grinding. Dureli the admixture, the mortar produced nisse the ability to prevent the passage of water with certainty. At the same time, they are resistant to chemical attacks.
They resist the action of ammonia, Raueligas, weak acids, for example sulphurous acid, nitric acid salts, etc. The additive can be used in this way. design so that it is immediately available or is ready to ship. It can also be produced in-house in the CT containers intended for shipping.
