发明名称 Oxidative post-treatment of carbon black
摘要 <p>An oxidatively aftertreated carbon black has a content of volatile constituents of more than 10 wt. %, based on its total weight, and the ratio of its CTAB surface area to the iodine adsorption number is greater than 2 m2/mg. The carbon black may be a channel black oxidatively aftertreated with ozone. The carbon black according to the invention is used preferably as pigment carbon black for the production of water-based paints, printing inks and as inks for mechanical and manual recording and drawing instruments. The combination of properties imparts to the carbon black an excellent dispersibility in water-based binder systems. The paints, printing inks and printer inks produced from this carbon black have an outstanding stability in storage.</p>
