Abstract
Description
Die Erfindung betrifft ein Synthetisches Polymer, welches Ruß und Bariumsulfat enthält, Verfahren zu dessen Herstellung und dessen Verwendung.The invention relates to a synthetic polymer which contains carbon black and barium sulfate contains, processes for its preparation and its use.
Synthetische Polymere, die unter Verwendung von Pigmentrußen hergestellt werden, weisen oftmals den Nachteil auf, dass die Rußpartikel zur Agglomeration neigen. Diese Agglomerate führen beim Spinnen der synthetischen Polymeren zu Filterdruckanstiegen und Filterblockaden und bei den erhaltenen Fasern kommt es verstärkt zu Filamentbrüchen. Auch wird von erhöhten Abrasionseffekten berichtet, die ebenfalls auf Rußagglomerate in den synthetischen Polymeren zurückgeführt werden.Synthetic polymers made using pigment blacks often have the disadvantage that the soot particles for agglomeration tend. These agglomerates result in the spinning of the synthetic polymers Filter pressure increases and filter blockages and comes with the fibers obtained it reinforces filament breaks. It also has increased abrasion effects reported also on soot agglomerates in the synthetic polymers to be led back.
Aufgabe der vorliegenden Erfindung ist es, ein synthetisches, Ruß enthaltendes Polymer bereitzustellen, das nicht die Nachteile des Standes der Technik auf weist und das sich insbesondere durch eine bessere Filtrierbarkeit und eine tiefere Farbwirkung auszeichnet. Weiterhin sollen sich die aus diesem Polymer hergestellten Fasern durch weniger Filamentbrüche und durch eine geringere Abrasion auszeichnen.The object of the present invention is a synthetic, containing carbon black To provide polymer that does not have the disadvantages of the prior art points and that is particularly due to better filterability and distinguishes deeper color effect. Furthermore, they are said to consist of this polymer Fibers produced by fewer filament breaks and less Mark abrasion.
Gelöst wird die Aufgabe durch ein synthetisches Polymer, welches Ruß und Bariumsulfat enthält. Es wurde gefunden, dass in synthetischen Polymeren, die Ruß und Bariumsulfat enthalten, eine Verbesserung des Verteilungsgrades der Rußpartikel im Polymer erreicht wird, was mit einer Verringerung der Anzahl von Rußflockulaten einhergeht. Dadurch wird eine tiefere Farbwirkung und eine bessere Ausnutzung der Pigmentpartikel erreicht. Auch die Verarbeitungseigen schaften des erfindungsgemäßen synthetischen Polymers sind verbessert, so lässt sich das erfindungsgemäße Polymer beim Fasersprinnprozess besser filtrieren und die gewonnenen Fasern weisen weniger Filamentbrüche und eine geringere Abrasion auf. The task is solved by a synthetic polymer, the soot and Contains barium sulfate. It has been found that in synthetic polymers that Contain carbon black and barium sulfate, an improvement in the degree of distribution of the Soot particles in the polymer is achieved, which results in a reduction in the number of Soot flocculate. This creates a deeper color effect and a better utilization of the pigment particles achieved. Even the processing properties properties of the synthetic polymer according to the invention are improved, so the polymer according to the invention can be better in the fiber spinning process filter and the fibers obtained have fewer filament breaks and one less abrasion.

Besonders bevorzugt sind ein Rußanteil von 0,2 bis 25 Gew.-% und ein BaSO4-Anteil von 0,1 bis 10 Gew.-%. Als bevorzugt für synthetische Polymere, die in der Faserproduktion Verwendung finden sollen, haben sich ein Rußanteil von 0,5 bis 5 Gew.-% und ein BaSO4-Anteil von 0,5 bis 10 Gew.-% erwiesen. Das Gewichtsverhältnis von BaSO4 zu Ruß kann mit 0,5 : 1 bis 5 : 1, bevorzugt mit 1 1 bis 3 : 1 gewählt werden.The synthetic polymer preferably contains polyethylene terephthalate, a polyamide, polypropylene or viscose. The carbon black fraction is preferably 0.1 to 35% by weight and the BaSO 4 fraction 0.05 to 20% by weight, in each case based on the polymer. A soot content of 0.2 to 25% by weight and a BaSO 4 content of 0.1 to 10% by weight are particularly preferred. A soot content of 0.5 to 5% by weight and a BaSO 4 content of 0.5 to 10% by weight have proven to be preferred for synthetic polymers to be used in fiber production. The weight ratio of BaSO 4 to carbon black can be selected with 0.5: 1 to 5: 1, preferably with 1 1 to 3: 1.
Zur Herstellung eines synthetischen Polymers, enthaltend Ruß und Bariumsulfat, wird eine BaSO4 und Ruß enthaltende Suspension in eine polymere Schmelze eingebracht.

Zur Herstellung der Suspension können Ruß und BaSO4 in Wasser oder in einem Glycol (z. B. Monoethylenglycol, Propandiol, Butandiol) suspendiert werden. Diese Suspendieren kann z. B. durch eine Vermahlung von Ruß und BaSO4 in Wasser oder einem Glycol vorge nommen werden.To produce a synthetic polymer containing carbon black and barium sulfate, a suspension containing BaSO 4 and carbon black is introduced into a polymer melt. The suspension can be introduced into the polymer melt in such a way that the suspension can be z. B. is fed to the usual reactors in polyamide production or z. B. in the polyester production esterification or poly condensation autoclaves is added. To prepare the suspension, carbon black and BaSO 4 can be suspended in water or in a glycol (e.g. monoethylene glycol, propanediol, butanediol).
