Carbon black, process for producing it, as well as its use

摘要

Invention Patent: "BLACK-OF-SMOKE, PROCESS FOR THE PRODUCTION OF THE SAME, AS WELL AS ITS USE". Smoke black according to the invention is characterized by an STSA surface of between 20 and 180 m ^ 2 ^ / g, an absorption of 24M4-DBP of between 40 and 140 ml / 100 g, a specific BET surface of between 20 and 250 m ^ 2 ^ / g, due to the fact that it contains 0.01 to 20% by weight of silicon, in relation to its total weight and that it has a tan sym ~ 0 ~ tan sym ~ 60 ~ greater than 3.37-0.0068.STSA. The carbon black according to the invention is produced by adding silica compounds, which are mixed with the raw material black carbon during its oxidative pyrolysis and, optionally, using carbon black oil as a fuel. carbon black according to the invention can be used as a filler in rubber mixtures, preferably for tires.
