PROBLEM TO BE SOLVED: To provide a white mixture of a filler with an organosilicone compound having improved storage properties. SOLUTION: A mixture, which can be incorporated into a rubber mixture, of at least one filler comprising a surface-treated, hydrophobic precipitated silica with an organosilicon compound represented by general formula I: Y-Sx-Z is manufactured by spraying the organosilicon compound on homogeneously surface-treated, hydrophobic precipitated silica in a mixing apparatus at a temperature of lower than 50 deg.C. This mixture has white, powdery and dry appearances and exhibits good processability and storage stability. |
