| 摘要 |
In the present invention, there is disclosed a process for preparing an elastomer composite blend comprising elastomer, particulate filler and optionally other ingredients, wherein the preparation process is characterized by: feeding a continuous flow of first fluid comprising elastomer latex to a mixing zone of a coagulum reactor; feeding a continuous flow of second fluid comprising particulate filler under pressure to the mixing zone of the coagulum reactor to form a mixture with the elastomer latex, the particulate filler being effective to coagulate the elastomer latex and the mixing of the first fluid and the second fluid within the mixing zone being sufficiently energetic to substantially completely coagulate the elastomer latex with the particulate filler in the coagulum reactor; discharging a substantially continuous flow of elastomer composite from the coagulum reactor; and dry mixing the elastomer composite with additional elastomer to form elastomer composite blend. The invention also relates to elastomer composite blends prepared in the above-described manner. |
