摘

本设计为年产7.5万吨乳聚丁苯橡胶装置聚合工段工艺设计，在文献调研和现场调研的基础上，进行了丁苯橡胶生产方法及工艺的论证，确定了以丁二烯、苯乙烯为单体，采用氧化还原体系为引发剂，歧化松香酸甲皂为乳化剂，配合其他助剂进行低

温乳液共聚合的生产工艺。在掌握各种物料的基本性质、聚合机理、聚合方法、工艺

流程以及国内外的发展现状的基础上，进行聚合工段的物料衡算、热量衡算、设备选型计算，并对丁苯橡胶车间进行了技术经济分析。在此基础上绘制出丁苯橡胶工艺流程图、设备布置图、管道布置图，编制了设计说明书.

The design for the 65,000 tons annual production capacity ofpolystyrene-butadiene

srubber emulsion polymerization plant process design section, in the literature research and

field research on the basis of a styrene-butadiene rubber production methods and t

technology demonstration to determine a butadiene, styrene for the monomer, the redox

rinitiator system, a disproportionation rosin acid soap as emulsifier, in conjunction with aother 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
