| 摘要 |
THE INVENTION RELATES TO AN OXIDATIVELY AFTERTREATED CARBON BLACK. IT IS CHARACTERISED IN THAT ITS CONTENT OF VOLATILE CONSTITUENTS IS MORE THAN 10 WT.%, BASED ON ITS TOTAL WEIGHT, AND THE RATIO OF ITS CTAB SURFACE AREA TO THE IODINE NUMBER IS GREATER THAN 2 M2/MG. THE CARBON BLACK ACCORDING TO THE INVENTION IS USED PREFERABLY AS PIGMENT CARBON BLACK FOR THE PRODUCTION OF WATER-BASED PAINTS, RINTING 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 IT HAVE AN OUTSTANDING STABILITY IN STORAGE. |
