Description

Verfahren zur Herstellung von in der Kälte schnellerhärtenden Phenol-Aldehyd-Harzen Es ist bekannt. Ph enol-Alclehyd-Harze, welche :erst so weit kondensiert sind, daß sie sich noch il flüssigem Zustand befinden, zu säurefesten Aüslleidungen und Bekleidungen von Apparateei und zur Herstellung von Säurebauten -und Anstrichfarben zu verwenden. Bisher wurden diese flüssigen Kunstharze entweder durch Wärme oder durch Säure oder saure Salze gehärtet bzw. zu Ende kondensiert. Auch die Verwendung von basischen Stoffen als Zusatzstoffe für Phen.ol-Aldehyd-Harze, um deren Erhärten in der Kälte herbeizuführen, ist bereits bekannt.Process for the production of phenol-aldehyde resins which harden faster in the cold It is known. Ph enol-Alclehyd resins, which: are only condensed so far that they are still in a liquid state, to acid-resistant clothes and garments of apparatus and for the production of acidic structures and paints to be used. Up until now, these liquid synthetic resins were produced either by heat or by acid or acid salts hardened or condensed to the end. Also the use of basic Substances as additives for phenol-aldehyde resins, in order to harden them in the cold to bring about is already known.

Es wurde nun gefunden, daß man diese flüssigen Kunstharze auch durch Zusatz von gegen, Wasser neutral reagierenden Metalldioxyden, in der Kälte härten kann. Dies ist vor allen Dingen für die Herstellung von säurefesten Auskleidungen und Bauten wertvoll, da man: hierfür naturgemäß keine so säureempfindlichen Materialien, wie basische Zusatzstoffe benutzen kann und andererseits das Arbeiten mit neutralen kondensationsmitteln keine Belästigung für Arbeiter und keine Beschädigung des zu schützenden Materials durch Säuren mit sich bringt.It has now been found that these liquid synthetic resins can also be used Addition of metal dioxides, which react neutrally to water, harden in the cold can. This is especially important for the production of acid-proof linings and buildings are valuable because: naturally there are no materials that are so sensitive to acid, how to use basic additives and on the other hand working with neutral ones condensation agents no nuisance to workers and no damage to the too protective material by acids.

Die neutralen Metalldioxyde werden entweder für sich allein oder in Verbindung mit Füllstoffen, gegebenenfalls. außerdem -noch unter Zusatz gut wärmeleitender Materialien, wie beispielsweise Silicium, Siliciumlegierungen und Graphit den flüssigen Phenol-Aldehyd-Harzen beigemischt. Die Erhärtung der Masseil erfolgt bei gewöhnlicher Temperatur und wird bereits; durch verhältnismäßig geringe Mengen der Zusatzstoffe erreicht. Die mit solchen Massen hergestellten Kittangen, oder Verputze sind fest, hart und widerstandsfähig gegen Druck, Reibung und gegen Säureangriff. Ein besonderer Vorteil. gegenüber den, durch saure Zusatzstoffe erhärtenden Kunstmassen besteht darin, daß mit diesen: neuen Mischungen auch auf Metallflächen gearbeitet werden kann, da diese nicht angegriffen. werden.The neutral metal dioxides are either on their own or in Connection with fillers, if appropriate. in addition, with the addition of good thermal conductivity Materials such as silicon, silicon alloys and graphite are the liquid ones Phenol-aldehyde resins mixed in. The hardening of the masseil takes place with ordinary Temperature and is already; due to relatively small amounts of the additives achieved. The putty bars or plasters made with such masses are solid, hard and resistant to pressure, friction and acid attack. A special Advantage. compared to the synthetic masses hardened by acidic additives in the fact that these new mixtures can also be used on metal surfaces can, as this is not attacked. will.

Beispiel. z5 Teile Bleidioxyd oder Mangandioxyd, ¢o Teile feine amorphe Kieselerde und ¢o Teile Quarzmehl werden zusammengemischt und dann. mit flüssigem Phenol-Aldehyd-Harz zu einer plastischen, gut verarbeitbaren Mörtelmasse vermengt, die zuverlässig innerhalb 48 Stunden erstarrt.Example. z5 parts lead dioxide or manganese dioxide, ¢ o parts fine amorphous Silica and ¢ o parts of quartz flour are mixed together and then. with liquid Phenol-aldehyde resin mixed into a plastic, easily workable mortar mass, which solidifies reliably within 48 hours.
