Description

Schalölemulsionen Um zu verhindern. daß bei der Aufführung von Betonbauten die zur Verschalung verwendeten Bretter oder Bleche an der Betonmasse festkleben, bestrich man bisher dieselben mit (Mineral-)Ölen. hauptsächlich in wäßriger Dispersion. um einen wirksamen Trennfilm zu erzielen.Formwork oil emulsions To prevent. that in the performance of concrete structures Glue the boards or sheets used for the formwork to the concrete mass, So far, they have been smeared with (mineral) oils. mainly in aqueous dispersion. to achieve an effective release film.

Trennüberzüge aus solchen Ölen besitzen jedoch den Nachteil, daß diese einerseits leicht in die Tiefe des Holzes eindringen und damit ihre Funktion als Zwischenschichten einbüßen, andererseits die. Betonoberfläche verunreinigen, wodurch es später unmöglich wird, einen gut haftenden Verputz auf diesen- anzubringen.However, release coatings made from such oils have the disadvantage that these on the one hand easily penetrate into the depth of the wood and thus its function as Lose intermediate layers, on the other hand the. Contaminate concrete surface, causing it later becomes impossible to apply a well-adhering plaster to this.

Es wurde nun gefunden, daß durch Zugale von technischem Rohmontanharz zu solchen Ölen eine Schalölemulsion entsteht, mittels der auf dem Schalmaterial ein Filin ausgebildet werden kann, der wachsartig und zugleich flexibel ist und so weder in (las Holz eindringt noch auf der Betonoberfläche Spuren hinterläßt. Das ganze aufgestrichene Material dient daher allein dazu, den Trennfilm auszubilden, wodurch der Aufstrich bedeutend dünner gehalten werden kann als bei den bisher üblichen Mitteln. Für den angestrebten Zweck reicht Min allgemeinen ein Zusatz von 20 bis 90°/o, bezogen auf die Gesamtnienge der nicht wäßrigen Bestandteile, aus. In einzelnen Fällen können jedoch auch kleinere oder größere 'Mengen verwendet werden. Technisches Rohmontanharz enthält bis zu 50% Wachsanteile. die den genannten Effekt noch weitgehend unterstützen.It has now been found that by adding technical raw montane resin to such oils a formwork oil emulsion is created, by means of which on the formwork material a filin can be formed that is waxy and flexible at the same time so neither in (read wood penetrates nor leaves traces on the concrete surface. The entire painted material therefore serves solely to form the separating film, whereby the spread can be kept significantly thinner than with the usual ones up to now Means. For the intended purpose, an addition of 20 to Min is generally sufficient 90%, based on the total amount of non-aqueous components. In individual In cases, however, smaller or larger amounts can also be used. Technical Raw montane resin contains up to 50% wax. which still largely have the effect mentioned support.

Es wurde auch schon vorgeschlagen, hloittanwa.chs in Scha.löleinulsionen zu verwenden. Dieses bildet jedoch für sich allein einen spröden, abblätternden Filin. Schalölemulsionen, die Montanwachs enthalten, sind abschmierende, lockere Pasten, während Schalöleintilsionen, die Rohniontanharz an Stelle von Montanwachs enthalten, einen lackartigen, festen und flexiblen Überzug ergeben. Die Verwendung von ,Montanharz an Stelle von Montanwachs bei der Herstellung von Schalöleinulsionen stellt, abgesehen von den technischen Vorteilen, auch einen sehr wesentlichen wirtschaftlichen Fortschritt dar. Während es für Montanwachs viel wirtschaftlicher ist, das Produkt in hochwertige Wachse überzuführen, hatte inan bisher für das bei diesem Prozeß anfallende chemisch und physikalisch völlig andersartige Rohmontanwachs keine genügende Verwendung. Es ist somit nach dem neuen Verfahren möglich, auch dieses bisher als Abfallprodukt betrachtete Erzeugnis in wirtschaftlicher Weise zu ver«-enden.It has also been suggested to use hloittanwa.chs in Scha.solein emulsions to use. However, this forms a brittle, flaky one on its own Filin. Formwork oil emulsions that contain montan wax are smeary, loose Pastes, during form oil inlays, which use rohniontan resin instead of montan wax contain, result in a varnish-like, firm and flexible coating. The usage von, Montan resin instead of montan wax in the production of form oil emulsions Aside from the technical advantages, it also represents a very important economic one Progress. While it is much more economical for montan wax, the product Inan had previously had to convert it into high-quality waxes in this process the chemically and physically completely different raw montan wax that arises is not sufficient Use. It is thus possible according to the new method, also this so far as Waste product considered product to be consumed in an economical manner.

Es wurde weiterhin gefunden, daß bei Zusatz von technischem Rohinontanharz die Herstellung einer Schalöleinulsion sehr erleichtert wird. da dieses ziisamnien mit Alkali sell);t als Einulgierinittel für (las Öl wirkt und so ein großer Teil eines Mineralölernulgators eingespart werden kann, der an sich für die Wirkungsweise des Öls überflüssig ist und außerdem zusätzliche Kosten verursacht. Man erhält z. B. mit Soda oder Pottasche und einem Bruchteil der Menge eines nichtionogenen Emulgators, die ohne Zusatz von Rohinontanharz notwendig wäre, eine Emulsion, die bei hohem Festkörpergehalt dünnflüssig ist und sich auch mit hartem Wasser beliebig verdünnen läßt, ohne auszuflocken.It has also been found that when technical raw rhinestone resin is added the production of a form oil emulsion is made much easier. because this ciisamnien with alkali sell); t as emulsifying agent for (las oil acts and so a large part a mineral oil emulsifier can be saved, which in itself for the mode of action of the oil is superfluous and also causes additional costs. One obtains z. B. with soda or potash and a fraction of the amount of a non-ionic emulsifier, which would be necessary without the addition of crude resin, an emulsion which at high Solid content is thin and can be diluted with hard water as required leaves without flaking.

The soda is dissolved in your boiling water and added to the melt while stirring. The cold water is then incorporated and the now finished emulsion is rapidly cooled.
