毕业设计摘要ABS树脂是聚丁二烯橡胶、单体苯乙烯和丙烯晴的接枝共聚物，它兼具三种组分的共同性能，无毒、无臭、耐冲击、质硬、尺寸稳定、耐化学腐蚀、电性能良好、易于成型加工，表面光洁和容易着色。ABS树脂是目前产量最大、应用最广的热塑性工程塑料。目前世界上ABS树脂合成仍广泛采用的是乳液接枝掺混法。该法是用乳液接枝法生产高胶的ABS接枝粉料作为中间品，将中间品于本体AS聚合物进行掺混。挤出造粒生产ABS树脂。该法工艺成熟、流程短、设备少、生产品种多、适宜大规模生产。本设计主要完成了ABS接枝粉料段的工艺流程设计、反应釜设计、车间布置设计、编制了设计。关键词：ABS树脂、工艺、乳液接枝掺混法AbstractABSresinisPolybutadieneRubber,styrenemonomerandacrylonitrilegraftcopolymer,itcombinesthreecomponentsofcommon,non-toxic,odourless,resistanttoshocks,thequalityishard,gooddimensionalstability,chemicalresistance,electricalproperties,easeofforming,thesurfaceissmoothandeasycoloring.ABSresinisbyfarthemostproductive,themostwidelyusedthermoplasticplastics.SynthesisofworldABSresinemulsiongraftedmixingmethodiswidelyused.ThisActwasproducedusingemulsiongraftinggraftingofABShighgluepowderasanintermediateproduct,intermediateintheontologyASpolymerblending.ExtrusiongranulationproductionofABSresin.TheActlessshortmaturetechnology,process,equipment,production,varieties,suitableformassproduction.ThisdesignABSgraftedpowderprocessdesign,plantlayoutdesign,reactordesign,preparationofdesignspecifications.Keyword:ABS,craft,lotioncopolymeriztion.目录第一章概述.............................................................................................1第二章生产配方及原料、辅助原料的技术规格....................................................42.1生产ABS粉料的配方及工艺条件...........................................................................42.1.1生产聚丁二烯乳胶的配方及工艺条件...........................................................42.1.2ABS接枝聚合的配方（质量份）..................................................................52.1.3生产ABS粉料的主要设备...............................................................................52.2原料规格..................................................................................................................6第三章工艺流程简述.............................................................................................93.1简述..........................................................................................................................93.2生产基本原理...........................................................................................................93.2.1聚丁二烯乳胶的合成......................................................................................93.2.2ABS接枝共聚反应机理..................................................................................103.3生产工艺过程......................................................................................................113.3.1简述................................................................................................................113.3.2PBL的生产及单体回收的工艺过程..............................................................123.3.3生产ABS粉料的工艺过程.............................................................................133.4工艺技术特点........................................................................................................13第四章工艺计算............................
