In recent years, the Styrene-butadiene rubber is wildly used in everywhere for its low price and good property. This design is process design based on butadiene and styrene as raw materials, with an annual output of 10,000tons of SBR. By comparing with the present SBR polymerization production method, we make a decision to treat emulsion polymerization at low temperature as polymerization production method at last. In the design process, in accordance with the requirements of the mission design, I finished a more detailed material balance and energy balance. Through the process calculation and selection, I finally finished my design of polymerizer. The diameter of it is 2400mm and the height of it is 8000mm. I choose Brumagin-type impeller as impeller of the polymerizer. As to heatexchanger, I finally choose straight tube-type heatexchanger as the inner cooler of it. According to the above process calculation and design results, I draw the process flow diagram and main equipment. At the same time, I explained the security considerations of the process of production and the treatment of the three wastes. Key words：tyrene-butadiene rubber; low temperature emulsion polymerization; process design; polymerizer 目 录 摘 要 I Abstract II 1. 概述 1 1.1丁苯橡胶的橡胶的发展历史 1 1.2未来的发展前景 2 1.3丁苯橡胶的分类 3 1.4丁苯橡胶的结构、性能和用途 4 1.4.1丁苯橡胶的结构 4 1.4.2丁苯橡胶的性能 4 1.4.3丁苯橡胶的用途 5 1.5丁苯橡胶的生产技术 5 1.5.1乳液聚合(ESBR) 5 1.5.2溶液聚合(SSBR) 6 2. 低温乳液聚合丁苯橡胶工艺设计 8 2.1低温乳液聚合丁苯橡胶的条件 8
