Description

Für die Färbung von Anstrichmitteln bzw. Weichmacher enthaltenden Kunststoffen werden häufig Präparationen verwendet, die das Pigment bereits in ■ vordispergierter Phase enthalten und dem Verarbeiter die Mühe der eigenen Dispergierung ersparen. Von den verschiedenen Möglichkeiten hatte sich bislang die Verwendung des Produktes »Di-(phenoxyäthyl)-formal« als Trägermaterial für viele Pigmentzubereitungen als besonders geeignet erwiesen. Der Verwendung des vorgenannten Produktes standen jedoch bei der Verarbeitung wegen seiner niedrigen Viskosität und bei der Anwendung im Hinblick auf die Verträglichkeit mit den verschiedensten Lacken und Kunststoffen erhebliche Schwierigkeiten gegenüber. Wegen seiner schlechten Verteilbarkeit in verschiedenen Bindemitteln kam es zu Reagglomerationen der Pigmente und damit zu Verlust von Farbstärke. Außerdem zeigten Präparationen auf der vorstehend genannten Trägerbasis eine mangelnde Lagerbeständigkeit.For the coloring of paints or plastics containing plasticizers are often used Preparations used that already contain the pigment in ■ the predispersed phase and the processor save the trouble of dispersing yourself. Of the various options had so far the use of the product "di- (phenoxyethyl) -formal" as a carrier material for many pigment preparations proved to be particularly suitable. The use of the aforementioned product stood however in processing because of its low viscosity and in application with a view to Compatibility with a wide variety of paints and plastics compared to considerable difficulties. Reagglomerations occurred because of its poor spreadability in various binders the pigments and thus a loss of color strength. In addition, preparations showed on the the aforementioned carrier base has a poor shelf life.

Schwierigkeiten traten auch bei der Herstellung solcher Präparationen auf. Es kann dabei zur Bildung von Formaldehyd unter Zersetzung des Trägerstoffes führen. Außerdem sind die genannten Präparationen nicht säurebeständig. Säurereste können aber jederzeit durch Pimente in die Präparation eingeführt werden. Difficulties also arose in the manufacture of such preparations. It can lead to education of formaldehyde with decomposition of the carrier. In addition, the preparations mentioned not acid-resistant. However, acid residues can be introduced into the preparation at any time through allspices.

Es wurde nun gefunden, daß sich die genannten Schwierigkeiten vermeiden lassen, wenn man als Trägerstoff einen chlorierten Kohlenwasserstoff einsetzt, der sich von η-Paraffin ableitet, mit einem Molekulargewicht von ca. 400-600 und einem Halogengehalt von 50-60% und eine Viskosität von ca. 25000 cP, bestimmt nach DIN 51550. Wenn eine solche Pigmentpräparation mit dem genannten Trägerstoff in acrylathaltigen Anstrichmitteln Verwendung finden soll, empfiehlt sich ein Zusatz zu dem als Grundsubstanz verwendeten chlorierten aliphatischen Kohlenwasserstoff in Form der Beimischung eines Copolymerisates aus Butylmethacrylat und Methylacrylat (Dichte 1,05 g/cm3, Säurezahl 7-9 mg KOH/g) bzw. eines Vinyltoluol-Acrylat-Copolymerisates (Dichte 1,03 g/cm2, Säurezahl 6-7 mg KOH/g, Erweichungsbereich 130-140° C). Durch diese Zusätze wird nicht nur die Verarbeitung in acrylathaltigen Anstrichmitteln wesentlich verbessert, sondern man erzielt auch einen deutlichen Farbstärkegewinn. Die Zusätze des Mischpolymerisates bzw. des Copolymeres liegen zwischen 20 und 70 %, bezogen auf das als Hauptanteil eingesetzte Bindemittel, den chlorierten aliphatischen Kohlenwasserstoff.It has now been found that the difficulties mentioned can be avoided if the carrier used is a chlorinated hydrocarbon derived from η-paraffin, with a molecular weight of about 400-600 and a halogen content of 50-60% and a viscosity of approx. 25,000 cP, determined according to DIN 51550. If such a pigment preparation with the carrier mentioned is to be used in acrylate-containing paints, it is advisable to add a copolymer of butyl methacrylate and methyl acrylate to the chlorinated aliphatic hydrocarbon used as the base substance (density 1.05 g / cm 3 , acid number 7-9 mg KOH / g) or a vinyltoluene-acrylate copolymer (density 1.03 g / cm 2 , acid number 6-7 mg KOH / g, softening range 130-140 ° C ). These additives not only significantly improve processing in acrylate-containing paints, but also achieve a significant increase in color strength. The additions of the mixed polymer or the copolymer are between 20 and 70%, based on the binder used as the main component, the chlorinated aliphatic hydrocarbon.
