Abstract:
1. An elastomer composite comprising substantially coagulated elastomer in which particulate filler has been dispersed by: feeding a continuous flow of first fluid comprising elastomer latex to a mixing zone of a coagulum reactor defining an elongate coagulum zone extending from the mixing zone to a discharge end; 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 mixture passing as a continuous flow to the discharge end, and the particulate filler being effective to coagulate the elastomer latex, wherein mixing of the first fluid and the second fluid within the mixing zone is sufficiently energetic to substantially completely coagulate the elastomer latex with the particulate filler prior to the discharge end; discharging a substantially continuous flow of elastomer composite from the discharge end of the coagulum reactor; feeding the elastomer composite from the discharge end of the coagulum reactor to a continuous compounder having multiple parallel elongate rotors axially oriented in an elongate processing chamber; processing the elastomer composite through the processing chamber of the continuous compounder by controlled operation of the rotors; and discharging the elastomer composite from a discharge orifice of the continuous compounder.
