Abstract:
1. A method of producing an elastomer composite, comprising: feeding a continuous flow of a first fluid comprising elastomer latex to a mixing zone of a coagulum reactor; feeding a continuous flow of a second fluid comprising particulate silica-containing filler under pressure to the mixing zone of the coagulum reactor to form a mixture with the elastomer latex, the feeding of the second fluid against the first fluid within the coagulum reactor being sufficiently energetic to coagulate at least a portion of the elastomer latex as the elastomer latex is mixed with the particulate silica-containing filler in the coagulum reactor; and further comprising introducing at least one coupling agent and introducing at least one amine-type antioxidant, such that the particulate silica-containing filler contacts the coupling agent prior to the silica-containing filler contacting the amine-type antioxidant, and wherein the coupling agent is introduced in the mixing zone or after the mixture exits the mixing zone.
