Description
Verfahren zur Herstellung von in der Kälte schnell erhärtenden säure- und alkalibeständigen blassen. Es ist schon ein Verfahren vorgeschlagen worden, nach dem in der gälte schnell er härtende Phenolformaldehydharzmassen in der Weise hergestellt werden, @dass Phenol formaldehydharze, die erst soweit kondensiert sind, dass sie sich noch in flüssigem Zustand befinden, mit gegen Wasser neutral reagie renden Aralkylchloriden und -sulfaten ver setzt werden.
Es wurde nun gefunden, dass. man an Stelle der Aralkylchloride oder -sulfate auch aliphatische Ester verwenden kann, falls man ausser diesen Verbindungen noch solche Zu satzstoffe von saurer oder neutraler Reaktion in den Mischungen verwendet, die an sich be reits die Verfestigung der Phenolformaldehyd- massen bewirken, wie z.
B. aromatische Sulfochloride. Gegebenenfalls können neben den aliphatischen Estern noch die genannten Aralkylchloride und -sulfate verwendet wer den.
Zweckmässig geht die Bereitung der Mas sen so vor sich, dass das vorkondensierte, noch flüssige Phienolformaldehydharz oder seine Lösung mit,den oben erwähnten aliphatischen Estern oder esteraxtigen Verbindungen ver mischt und aufbewahrt wird. In diesem Falle werden zweckmässig solche Ester verwendet,
die an sich noch nicht eine Härtung der lIarz- massen bewirken. Für den Gebrauch wird das erwähnte flüssige Gemisch dann mit einem festen Kittmehl vermengt, das die Erhär- tungsstoffe, z. B. aromatische Sulfochlaride, aber auch saure oder neutrale Persulfate, Titansulfat, oder Metalldioxyde wie Blei superoxyd oder Mangandiogyd in fester Form und daneben zweckmässig auch noch indiffe rente Füllstoffe enthält.
Mit derartigen in der Kälte schnell erhär tenden Massen können Kittangen, Verputze oder betonartige Beläge wie auch Formkör per, z. B. Steine, Platten oder auch Filter- steine oder Filterböden, hergestellt werden, die fest, hart und widerstandsfähig gegen mechanischen und chemischen Angriff sind. Bei Verwendung geeigneter flüssiger Phenol- formaldehydharze, z.
B. solcher, bei denen ein Mol-Verhältnis von Phenol zu Form aldehyd wie 1 :1,4 vorliegt (aber auch je nach der Art der zugesetzten esterartigen Verbindungen mit andern Mol-Verhä.ltnissen), erhält man Erzeugnisse, aie nicht nur gegen Säuren, sondern auch gegen Alkalien bestän dig sind.
Es ist besonders darauf hinzuweisen, dass gegenüber den bisher bekannten Erhärtungs- stoffen oder Erhärtungsmitteln erst die Kom bination der erwähnten Ester oder esterarti- gen Verbindungen mit den an sich die Ver festigung bewirkenden Stoffen die Erzielung einer besonders guten chemischen Beständig keit, namentlich gegen Alkalien, ermöglicht.
Die aliphatischen Ester oder esterartigen Verbindungen können auch mit andern Ver- festigungsmitteln verwendet werden, die an sich nicht als Erhärtungsmittel wirken, aber zusammen mit diesen andern Zusatzstoffen eine völlige chemische Beständigkeit hervor rufen.
Die genannten Ester oder esterartigen Verbindungen können gegebenenfalls ausser dem noch unter Zusatz gut wärmeleitender Stoffe, z. B. Silizium, Siliziumverbindungen oder Graphit, den flüssigen Formaldehyd harzen zusammen mit den Erhärtungsstoffen beigemischt werden.
Beispiel: 10 Gewichtsteile Paratoluolsulfochlorid werden mit 60 Gewichtsteilen Bariumsulfat und 20 Gewichtsteilen grobkörnigen Quarz- mehlen miteinander vermischt und das Ein mehl mit einer Anmischflüssigkeit, bestehend aus 30 Volumteilen vorkondensiertem flüssi gem Phenolformaldehy dha.rz und 10 Volum- teilen Dichloipropanol,
angemischt. An Stelle. von Dichlorpropanol oder zu sammen mit diesem können auch verwendet werden: Glykolcblorhydrin, Epichlorhydrin, ,Äthy.lencliloi#id, Diätliylsulfat, alkvlsehwefel- saure Salze und andere ähnliche Ester und esterartige Verhindungen.
Process for the manufacture of acid and alkali-resistant pale products which harden quickly in the cold. A process has already been proposed according to which rapidly hardening phenol-formaldehyde resin compositions are produced in such a way that phenol-formaldehyde resins, which have only condensed to the point that they are still in a liquid state, with aralkyl chlorides that are neutral to water and sulphates.
It has now been found that, in place of the aralkyl chlorides or sulfates, aliphatic esters can also be used if, in addition to these compounds, additives with an acidic or neutral reaction are used in the mixtures which in themselves already cause the phenol-formaldehyde to solidify. cause mass, such.
B. aromatic sulfochlorides. In addition to the aliphatic esters, the mentioned aralkyl chlorides and sulfates can optionally also be used.
The preparation of the masses expediently proceeds in such a way that the precondensed, still liquid phienol-formaldehyde resin or its solution is mixed with the above-mentioned aliphatic esters or ester-type compounds and stored. In this case, such esters are expediently used,
which in and of themselves do not yet cause hardening of the resin. For use, the above-mentioned liquid mixture is then mixed with a solid cement flour, which contains the hardening substances, e.g. B. aromatic sulfochlaride, but also acidic or neutral persulfate, titanium sulfate, or metal dioxides such as lead superoxide or manganese diogyd in solid form and also useful indifferent fillers.
With such in the cold fast-hardening masses can putty bars, plastering or concrete-like coverings as well as Formkör by, z. B. stones, plates or even filter stones or filter floors, which are firm, hard and resistant to mechanical and chemical attack. When using suitable liquid phenol-formaldehyde resins, e.g.
For example, those in which the molar ratio of phenol to formaldehyde is 1: 1.4 (but also, depending on the type of ester-like compounds added with different molar ratios), one obtains products, not only against Acids, but are also resistant to alkalis.
It should be pointed out in particular that, compared to the hardening substances or hardening agents known to date, only the combination of the esters or ester-like compounds mentioned with the substances that actually cause the hardening can achieve particularly good chemical resistance, in particular to alkalis, enables.
The aliphatic esters or ester-like compounds can also be used with other solidifying agents which do not act as hardening agents per se, but which together with these other additives produce complete chemical resistance.
The esters or ester-like compounds mentioned can optionally also be used with the addition of highly thermally conductive substances such. B. silicon, silicon compounds or graphite, the liquid formaldehyde resins are mixed together with the hardening substances.
Example: 10 parts by weight of paratoluene sulfochloride are mixed with 60 parts by weight of barium sulfate and 20 parts by weight of coarse-grained quartz flours and the single flour is mixed with a mixing liquid consisting of 30 parts by volume of precondensed liquid phenolformaldehyde dha.rz and 10 parts by volume of dichloipropanol,
mixed. Instead of. of dichloropropanol or together with this can also be used: Glykolcblorhydrin, Epichlorhydrin, Äthy.lencliloi #id, Dietliylsulfat, Alkvlesulfur acid salts and other similar esters and ester-like compounds.
