Process for the manufacture of waxes for carbon paper

For coating carbon paper waxes are required which are not only capable to disperse high amounts of carbon black but also have good oil binding properties. For this purpose natural waxes carrying ester groups are treated with oxygen until they have a high carbon black absorption. The waxes are oxidiz...

Beschreibung
Zusammenfassung:	For coating carbon paper waxes are required which are not only capable to disperse high amounts of carbon black but also have good oil binding properties. For this purpose natural waxes carrying ester groups are treated with oxygen until they have a high carbon black absorption. The waxes are oxidized in the melt. They can also be oxidized in admixture with hydrocarbon waxes or the derivatives thereof.
