Description

Verfahren zur Herstellung von physikalisch hochwertigen Lackgrundstoffen Gegenstand des Hauptpatents ist ein Verfahren zur Herstellung von physikalisch hochwertigen Lackgrundstoffen aus polymeren Kunststoffen. Das Verfahren besteht darin, daß die Lackgrundstoffe einer Wärmebehandlung bei einer Temperatur unterzogen werden, welche ohet'halb der Wärmebeständigkeit des betreffenden Stoffes liegt.Process for the production of physically high quality paint base materials The subject of the main patent is a process for the production of physically high-quality products Paint base materials made from polymer plastics. The procedure is that the Paint base materials are subjected to a heat treatment at a temperature which ohet'halb the heat resistance of the substance in question.

In manchen Fällen ist es nun nicht wünschenswert oder nicht möglich, die lackierten Gegenstände auf die dazu erforderlichen hohen Temperaturen zu bringen. Gegenstand der Erfindung ist ein Verfahren, um diese Schwierigkeit zu umgehen. Die Erfindung beruht auf der Erkenntnis, daß man die Wärmebehandlung der polymeren Kunststoffe bei wesentlich niedrigeren Temperaturen vornehmen kann, sofern man dem Kunststoff geringe Mengen von sauerstoffabspaltenden Stoffen, wie z. B. B:enzoylsuperoxyd, zusetzt. Man kommt nunmehr mit wesentlich niedrigeren Temperaturen aus und erreicht trotzdem eine wesentliche Verbesserung der physikalischen Eigenschaften. In Spalte 2 ist das Ergebnis einer Verlustfaktormessung bei 8oo Hz eingetragen, gemessen nach einer Wärmebehandlung des Lackfilmes bei i2oe von 3o Minuten Dauer. In Spalte 3 ist schließlich die Farbe des Lackes angegeben.

The invention relates to a method to circumvent this difficulty. The invention is based on the knowledge that the heat treatment of the polymeric plastics can be carried out at much lower temperatures, provided that the plastic is given small amounts of oxygen-releasing substances, such as. B. B: enzoyl superoxide added. You can now get by with much lower temperatures and still achieve a significant improvement in the physical properties. Column 2 shows the result of a dissipation factor measurement at 8oo Hz, measured after heat treatment of the paint film at i2o for 30 minutes. Finally, column 3 shows the color of the paint. I.
