PRODUCTION METHOD OF SURFACE-TREATED CARBON BLACK

摘要

PPROBLEM TO BE SOLVED: To provide a production method of surface treated carbon black which can be used for producing a rubber composition being improved in abrasion resistance and lowered in rolling resistance. PSOLUTION: The surface-treated carbon black is produced by (A) a step in which carbon black is subjected to a water vapor plasma treatment at 100C so as to have a surface hydroxy amount of 0.25-0.55 mmol/g, and (B) a step in which a silane coupling agent is adsorbed on the carbon black by vapor phase adsorption after the step (A).
