CARBON BLACK SUSPENSION AND METHOD ITS PREPARING Russian patent published in 2006 - IPC C09C1/56 

FIELD: chemical industry.

SUBSTANCE: method for preparing carbon black suspension involves dispersing carbon black for 60-70 min with a component containing leukanol and water wherein the leukanol source represents sewage water - serum from manufacture of butadiene-styrene rubber and comprising potassium soaps of disproportionate colophony and fatty acids additionally. Carbon black crude dispersion is prepared that is subjected for stabilization for 5-10 min by using a high-speed mixture and alkali addition to provide pH = 9-10. The prepared carbon black suspension comprises the following components, wt.-%: carbon black, 15.0-40.0; potassium soaps of disproportionate colophony and fatty acids, 0.75-1.25; leukanol, 0.5-0.7; alkali, 0.03-0.05, and water, 58.00-83.72. Invention provides reducing the environment pollution and decreasing const of carbon black suspension. Invention can be used in manufacturing synthetic rubbers used in making tires and other rubber-technical articles.

EFFECT: improved preparing method of suspension.
