溶液丁苯橡胶聚合工艺设计VIP免费

摘要本设计主要是对溶液丁苯橡胶聚合工艺进行设计，它的聚合机理为阴离子聚合，其目的是为了进一步明确S-SBR的聚合工艺，掌握其聚合机理，并选取适当的配方，降低耗能，提高产率，提高其性能。文献部分对溶液丁苯橡胶的发展史，聚合机理，各种配方，聚合过程，流程生产工艺，种类与性能，结构及应用等方面进行了阐述。在设计部分对聚合过程的物料平衡，热量平衡进行了计算，以及聚合反应器和搅拌桨的设计计算。整个过程参考了大量的相关文献，并对各类搅拌器和反应釜进行了比较，综合各搅拌器和聚合釜的优点，对已有的工艺进行了改进，提高了聚合效率。关键词：S-SBR，阴离子聚合，聚合工艺，间歇聚合，聚合釜AbstractThedesignismainlytodesignthesolutionstyrene-butadienerubberpolymerizationprocess.It’spolymerizationmechanismisanionpolymerization.ThepurposeofthedesignistofurthercatchontheS-SBRpolymerizationtechnics,masterthemechanism,choiceproperformulation,leasetheusingpower,improvetheyield,andimproveit’sperformance.TheliteratureisincludingthedevelopmenthistoryoftheS-SBR,polymerizationmechanism,differentkindsofformulation,polymerizationprocess,flowedproducetechnics,categories,property,construction,andapplicationandsoon.Besides,inthedesignpart,includethepolymerizationprocess’smaterielbalance,quantityoftheheatbalance,andpolymerizationkettle’sbeaterdesigncalculation.Duringthewholecourse,withamountofcorrelativeliterature,aftercomparingwiththedifferentbeatersandpolymerizationkettle,improvethepastmechanismandimprovethepolymerizationefficiency.Keywords:S-SBR,anionpolymerization,polymerizationmechanismintermittentpolymerization,polymerizationkettle目录第一章前言..............................................11．1总述.........................................................11．2内容简介.....................................................2第二章总论..............................................42．1文献.........................................................42．1．1S-SBR聚合反应机理－阴离子聚合：...............................42．1．2S-SBR的发展简史及与E-SBR的比较..............................52．1．3溶聚丁苯的结构、性能及应用：....................................82．1．4溶液丁苯橡胶的聚合工艺：........................................92．1．5生产控制因素...................................................14第三章设计............................................203．1物料衡算....................................................203．1．1设计要求：.....................................................203．1．2原料要求：.....................................................203.1.3配方要求:........................................................203.1.4反应时间及控制温度...............................................203.1.5计算过程：.......................................................213.2设备计算.....................................................233．2．1釜式聚合反应器的结构...........................................243．2．2确定反应釜釜身与封头形式.......................................243．2．3搅拌器的选择与确定.............................................243．2．4计算与设计部分.................................................253．3热量衡算....................................................303．3．1数据整理.......................................................303．3．2计算过程.......................................................30第四章问题与发展前景.....................................33第五章设计体会与收获....................
