Abstract

The design for the 65,000 tons annual production capacity ofpolystyrene-butadiene rubber emulsion polymerization plant process design section, in the literature research and field research on the basis of a styrene-butadiene rubber production methods and technology demonstration to determine a butadiene, styrene for the monomer, the redox initiator system, a disproportionation rosin acid soap as emulsifier, in conjunction with other additives for low-temperature emulsion copolymerization of the production process. In the grasp of the basic properties of various materials, polymerization mechanism, polymerization methods, the development process and the status quo at home and abroad based on the section of polymeric material balance, heat balance, calculation of equipment selection, and styrene-butadiene rubber plant techno-economic analysis carried out. On this basis SBR process to map out plans, equipment layout, piping layout, the preparation of the design specification and calculation of the book.

Key Words：Emulsion; styrene-butadiene rubber ;production technology
