Description

Verfahren zur Herstellung von Perlmutter- oder ähnlichen Glanzeffekten in Gußkörpern aus Phenol-Aldehyd-Kondensationsprodukten und Glanzpigmenten Es ist aus der Kuristhornindustrie bekannt, Perlmuttereffekte unter Zuhilfenahme von sogenannten Glanzpigmenten, insbesondere Bleiphosphat, hervorzurufen. Man hat auch schon vorgeschlagen, derartige Glanzpigmente für die Herstellung von Perlmutter- oder ähnlichen Glanzeffekten in Phenol-Aldehyd-Kondensationsprodukten zu verwenden. Dies stößt aber dann auf Schwierigkeiten, wenn die Phenol-Aldehyd-Kondensationsprodukte im flüssigen Zustande zur Anwendung kommen, weil hier das spezifisch schwere Bleiphosphat o. dgl. in der Masse zu Boden sinkt, bevor sie zum Erstarren gebracht wird, und auch leicht ein Zusammenballen des Glanzpigments eintritt, wodurch für den angestrebten Effekt wirkungslose Nester gebildet werden.Process for the production of mother-of-pearl or similar gloss effects in cast bodies made of phenol-aldehyde condensation products and luster pigments It is known from the Kuristhorn industry, mother-of-pearl effects with the help of so-called Cause luster pigments, especially lead phosphate. It has already been suggested such luster pigments for the production of mother-of-pearl or similar luster effects to be used in phenol-aldehyde condensation products. But this then comes up Difficulties when the phenol-aldehyde condensation products are in the liquid state come to use because here the specifically heavy lead phosphate o. The like. In the Mass sinks to the ground before it is solidified, and also easily sinks Agglomeration of the luster pigment occurs, as a result of which the desired effect is ineffective Nests are formed.

Es hat sich nun überraschenderweise gezeigt, daß die Herstellung von Perlmutter-oder ähnlichen Glanzeffekten in Gußkörpern aus Plienol-Aldehyd-Kondensationsprodukten dann sehr gut gelingt, wenn man die Glanzpigmente zunächst beispielsweise mit Hilfe einer Farbenreibmühle oder eines Walzwerks mit Glykol oder anderen zähflüssigen aliphatischen oder aromatischen Alkoholen, mit Ausnahme des Glycerins, oder deren Derivaten homogen verreibt und den Phenol-Aldehyd-Kondensationsprodukten zusetzt, während diese sich im flüssigen Zustand befinden, worauf das Gießen und die Härtung der Harze in bekannter Weise vorgenommen wird. Als Dispersions- oder Emulgiermittel kommen außer Glykol z. B. in Betracht: Benzylalkohol, Glykolmonoäthyläther, Diäthylenglykol, Polyäthylenglykol, Polyglycerin, Diäthylenglykol- und Polyäthylenglykoläther; ferner Phthalsäureester, Adipinsäureester, Naphthensäureester. DieseDispersions-oder Emulgiermittel müssen einerseits genügend zähflüssig sein oder genügend hohes spezifisches Gewicht besitzen, um das Glanzpigment in Schwebe zu halten, und müssen andererseits mit dem Phenol-Aldehyd-Kondensationsprodukt homogene Mischungen zu ergeben vermögen.It has now surprisingly been shown that the production of Mother-of-pearl or similar gloss effects in cast bodies made from plienol-aldehyde condensation products then works very well if you first use the luster pigments, for example a paint grinder or a rolling mill with glycol or other viscous ones aliphatic or aromatic alcohols, with the exception of glycerine, or their Disperses derivatives homogeneously and adds them to the phenol-aldehyde condensation products, while these are in the liquid state, followed by pouring and hardening the resins is made in a known manner. As a dispersing or emulsifying agent except glycol z. B. possible: benzyl alcohol, glycol monoethyl ether, diethylene glycol, Polyethylene glycol, polyglycerine, diethylene glycol and polyethylene glycol ethers; further Phthalic acid esters, adipic acid esters, naphthenic acid esters. These dispersants or emulsifiers must on the one hand be sufficiently viscous or sufficiently high specific weight own to keep the luster pigment in suspension, and on the other hand must with capable of giving the phenol-aldehyde condensation product homogeneous mixtures.

Man hat zwar auch schon daran gedacht, die oben gerügten Übelstände zu vermeiden. Der deshalb gemachte Vorschlag ging dahin, einzelne gefärbte Massebrocken, durch deren Vereinigung ein gemaserter Kunstgegenstand hergestellt werden sollte, j e mit einem andersfarbigen Klebmittel zu urnhüllen und sie alsdann zu verpressen. Auf diese Weise lassen sich aber perlmutterartige Effekte, bei denen das Glanzpigment homogen in der Masse verteilt sein muß, nicht erreichen. Andererseits hat man vorgeschlagen, bei der Herstellung von Anstrichmitteln die Pigmente zunächst mit einem Teil des Bindemit= tels innig zu vermischen und dann die..... haltene Masse mit dem übrigen Teil ä' Bindemittels zu vereinigen. Bei der Hers lung von Anstrichmassen liegen aber Verhältnisse grundsätzlich anders als beAir, Herstellung von Kunstmassen aus Gußharzen: Denn bei diesen muß zum Zwecke der Härtung der Harze ein längeres Erhitzen: der mit dem Glanzpigment versetzten, zunächst flüssigen Stoffe stattfinden, und es bestand die Gefahr, daß sich während dieser Zeit die spezifisch schweren Glanzpigmente bereits wieder absetzen würden, bevor die Kunstharze erhärteten. Es war nicht vorauszusehen, daß diese Gefahr würde umgangen werden können, wenn man die Glanzpigmente -zunächst mit einemDispersionsmittel der oben angegebenen Art vereinigte und dann erst den flüssigen Kunstharzen zusetzte.It is true that one has already thought of avoiding the abuses criticized above. The proposal made therefore was to encase individual colored chunks of mass, through the combination of which a grained art object should be produced, with a different colored adhesive and then to press them. In this way, however, mother-of-pearl-like effects in which the luster pigment must be homogeneously distributed in the mass cannot be achieved. On the other hand, it has been proposed, in the production of paints, first of all to mix the pigments intimately with part of the binder and then to combine the ..... retained mass with the remaining part of the binder. When it comes to the manufacture of paints, however, the situation is fundamentally different from that of beAir, the manufacture of synthetic compounds from cast resins: for these, in order to harden the resins, the initially liquid substances with the luster pigment must be heated for a longer period of time, and there was a risk that during this time the specifically heavy luster pigments would settle again before the synthetic resins hardened. It was not anticipated that this danger would be avoided if the luster pigments - united first with a dispersion medium of the type mentioned above and only then zusetzte the liquid resins.

Zur Ausführung des Verfahrens kann man z. B. so verfahren, daß man gleiche Teile trockenes Bleiphosphat und Glykol auf einer gewöhnlichen Farbreibmühle so lange vermahlt, bis eine dicke, homogene, kornfreie, ölartige Emulsion entstanden ist. Von dieser führt man r bis zo°/o in ein flüssiges Kunstharz ein, daß dann, wie üblich, weiterverarbeitet wird. Man erhält so nach der Härtung .des Harzes einen Körper mit einem shr schönen perlmutterartigen Effekt, der in einer Gleichmäßigkeit nach anderen Ver-KUhren unter Zuhilfenahme von trockenem "oder pastenförmigem Bleiphosphat allein nicht .erhalten werden kann. Die Körnchengröße 'des Pigments nach der Vereinigung mit dem Harz ist von wesentlicher Bedeutung für die Ausführung des Verfahrens.To carry out the method you can, for. B. proceed so that one equal parts dry lead phosphate and glycol on an ordinary paint grinder Ground until a thick, homogeneous, grain-free, oil-like emulsion is formed is. From this one introduces r to zo ° / o into a liquid synthetic resin, that then, as usual, is further processed. After hardening, the resin is obtained in this way Body with a beautiful mother-of-pearl-like effect that is uniform according to other methods with the aid of dry or pasty lead phosphate alone cannot .be obtained. The 'granule size' of the pigment after association using the resin is essential to running the process.
