Description

Verfahren zur Herstellung gipshaltiger Massen ki- Neubauten und beim Ausbessern von kleinen Schäden in Altbauten wird in großem Umfagg Gips verwendet. Hierbei wird gewöhnlich das gebrannte Material mit Wasser angerührt und unter Ausnützung von Kristallisa.tioÜserseheinungen der Gips abbinden, d. h. erhärten gelassen: Da die- Arbeiten im allgemeinen mit einer gewissen Sorgfalt ausgeführt werden müssen, d. h. eine gewisse Zeit für die handwerkliche Durchführung erfordern, ist das schnelle Abbinden des Gipses bei solchen Arbeiten ein Nachteil.Process for the production of gypsum-containing masses ki- new buildings and at Mending small damage in old buildings is largely used in plaster. In this case, the fired material is usually mixed with water and used Set the plaster of paris from Kristallisa.tioÜserseheinungen, d. H. let harden: There the work generally has to be carried out with a certain amount of care, d. H. require a certain amount of time to carry out the craftsmanship, this is fast Setting of the plaster is a disadvantage in such work.

Man, hat daher versucht, durch Zusatz von tierischem Leim den Abbindevorgang zu verlangsamen und hat mit dieser Arbeitsweise tatsächlich auch einen gewissen Vorteil erreicht. Jedoch behält der Gips nach dem -Abbinden seine bekannte Sprödigkeit bei mechanischer Beanspruchung, sei es durch Druck oder Stoß.Attempts have therefore been made to start the setting process by adding animal glue to slow down and actually has a certain something with this way of working Advantage achieved. However, the plaster of paris retains its known brittleness after it has set in the event of mechanical stress, be it through pressure or impact.

Es wurde nun gefunden, daß man für die Oberflächengestaltung von Wänden, Türen, Verzierungen u. dgl. die Abbindezeit des Gipses beliebig dadurch verzögern kann, daß man dem gebrannten Gips in trocknem oder in mit Wasser angerührtem Zustand in wasserfreien oder ;nahezu wasserfreien organischen Lösungsmitteln. unlösliche, wasserlösliche Cellutoseäther zusetzt.It has now been found that for the surface design of walls, Doors, decorations and the like delay the setting time of the plaster as desired it can be done with the plaster of paris in a dry state or in a state mixed with water in anhydrous or almost anhydrous organic solvents. insoluble, water-soluble cellulose ether added.

Ferner wurde die überraschende- Feststellung gemacht, daß ein in wasserfreien oder nahezu wasserfreien organischen Lösungsmitteln unlösliche, wasserlösliche Celluloseäther enthaltender Gips nach dem Abbinden eine elastischere und damit gegen mechanische Einflüsse weitgehend widerstandsfähige Struktur aufweist, wodurch ein solcher Gips außer zur Herstellung von Verzierungen auch besonders zum Ausbessern schadhafter Wände und zum Verlegen elektrischer Leitungen usw. durch Ausspachteln der Hohlräume verwendbä.r ist.Furthermore, the surprising finding was made that an in anhydrous or nearly anhydrous organic solvents insoluble, water-soluble cellulose ethers containing plaster after setting a more elastic and thus against mechanical Influences largely resistant structure, creating such a plaster of paris except for the production of decorations also especially for mending damaged ones Walls and for laying electrical cables etc. by filling the cavities is usable.

Der Zusatz der wasserlöslichen Celluloseäther zum Gips kann sowohl durch Vermischen in trockner Form als auch durch Zusatz zu durch wäßrige Aufschlemmung .erhaltenem Gipsbrei erfolgen.The addition of the water-soluble cellulose ether to the plaster of paris can do both by mixing in dry form as well as by adding to by aqueous slurry . obtained gypsum paste.

Letztere Ausführungsform des Verfahrens gestättet eine sehr stärke Verdünnung des Gipsbreis, da. der Zusatz der wasserlöslichen Celluloseätlier den Brei zu einer sämigen Masse verdickt, die sich notfalls auch mit dem Pinsel verarbeiten läßt. Hierdurch lassen sich ebenfalls für die Verwendung von Gips neue Effekte erzielen.The latter embodiment of the method allows a very strong Dilution of the Plaster of paris, there. the addition of water-soluble cellulose ethers thickens the pulp to a creamy mass, which can also be used with a brush if necessary can be processed. This also allows new plaster of paris to be used Achieve effects.

Es ist bekannt, zwecks. Herstellung harter und elastischer Massen Gips mit Lösungen von Bindemitteln oder ICebstoffen in ganz oder fast wasserfreien organischen Lösungsmitteln zu vermengen, wobei als solche Bindemittel unter anderem auch wasserlösliche Celluloseiither dienen sollen.It is known in order to. Production of hard and elastic masses Plaster of paris with solutions of binding agents or materials in completely or almost anhydrous to mix organic solvents, as such binders among other things water-soluble cellulose eggiths are also intended to serve.

Abgesehen davon, daß wasserlösliche Celluloseäther in ganz oder fast wasserfreien organischen Lösungsmitteln so gut wie unlöslich sind; wodurch das bekannte Verfahren mit «asserlöslichen Celluloseäthern als Bindemittel gar nicht ausführbar ist; wird das Ergeb-. nis des vorliegenden Verfahrens, nämlich die Verzögerung des Abbindens von Gipsmassen, durch das bekannte Verfahren nicht erreicht, da die nach diesem erhaltenen 'Gipsmischungen schon nach wenigen Minuten zu harten Massen erstarren. Beispiel, In 5o1 Wasser werden 0,26 Gewichtsteile celluloseglykolsaures Natrium .gelöst, worauf mit dieser Lösung . z oo leg Gips angemacht werden. Letzterer wird dadurch etwa z@ Minuten plastisch verformbar erhalten. Wünscht man den Gips i Stunde verformbar zu erhalten, so gebraucht man 0,46o Gewichtsteile *celluloseglykolsaures Natrium. Bei Verwendung von anderen bekannten wasserlöslichen Celluloseäthern ergeben sich ähnliche Zeiten.Apart from the fact that water-soluble cellulose ethers are as good as insoluble in completely or almost anhydrous organic solvents; whereby the known process with water-soluble cellulose ethers as binders cannot be carried out at all; the result will be. nis of the present method, namely the delay in the setting of gypsum compounds, is not achieved by the known method, since the gypsum mixes obtained after this solidify to form hard compounds after just a few minutes. Example, 0.26 parts by weight of sodium cellulose glycolate are dissolved in 5o1 of water, whereupon with this solution. z oo leg plaster of paris can be put on. The latter is thereby obtained plastically deformable for about z minutes. If one wishes to keep the plaster of paris deformable for one hour, 0.460 parts by weight * of sodium cellulose glycolate are used. When using other known water-soluble cellulose ethers, similar times result.
