Precoagulation process for incorporating organic fibrous fillers |
摘要 |
Incorporation of fibrous filler into a styrene-butadiene rubber (SBR) by mixing a fibrous filler, SBR latex and a coagulant, feeding the resulting coagulated fiber-filled SBR latex to a dewatering extruder and through a flow restriction that applies back pressure sufficient that water present in the SBR is forced out of a vent upstream from the flow restriction and discharging the fiber-filled SBR from the extruder.
