摘要：根据所下达的设计任务书，本设计进行了年产1000吨聚胺-聚丙烯酸酯嵌段共聚物的生产工艺设计。通过查阅了大量的文献资料，明确了嵌段共聚物的合成方法，以及合成聚胺-聚丙烯酸酯嵌段共聚物的原料配方。同时，也选择了更加成熟的工艺流程、生产设备等等，对生产过程的工艺参数、设备型号以及物料衡算都作了较为详细的阐述。
采用如下生产流程：以（甲基）丙烯酸甲酯等为单体，以二乙烯苯等为交联剂，以甲苯等为致孔剂，引发剂一般都是选用过氧化二苯甲酰（BPO）和偶氮二异丁腈（AIBN）中的一种或是二种按一定的比例搭配使用。油相一般由单体、交联剂、致孔剂、引发剂组成，水相主要由水和分散剂组成。油相和水相按一定比例混合，在一定速率的搅拌下，形成小液滴中进行悬浮聚合。具体的流程为：可先经过预聚成浆状物，然后在油相中成球。丙烯酸酯先与二乙烯苯共聚成珠状体，再在珠状体表面接枝胺类物质。用这种方法生产出来珠状的聚胺-聚丙烯酸酯嵌段共聚树脂。设计过程中，也尽量考虑了低成本、高性能、低污染、可循环的理念对车间较为合理的设计，并且绘制了工艺流程图和生产车间平面布置图。23704

An annual output of 1000 tons of polyurethane-Polyacrylate Copolymer production process design
Abstract: According to the design task book issued, the design of the annual output of 1000 tons of polyurethane - Polyacrylate Copolymer production process design. Through consulting a lot of literature, the synthesis method of block copolymer, and the synthesis of polyamines Polyacrylate Copolymer recipe. At the same time, also chose to process, more sophisticated production equipment and so on, the process parameters, process equipment and material balance calculation in detail.
Production process is as follows: The (meth) acrylate as the monomer, pinylbenzene as the crosslinking agent, using toluene as the porogen, the choice of initiator are generally dibenzoyl peroxide (BPO ) and azobisisobutyronitrile (AIBN) in one or two kinds of use with a certain proportion. Oil phase is generally a monomer, a crosslinking agent, porogen, initiator composition, the water phase mainly composed of water and a dispersing agent. An oil phase and an aqueous phase by mixing, at a rate of stirring, the formation of small droplets in suspension polymerization. Specific process: pre-polymerization may be a slurry, and then the oil phase into a ball. Acrylate copolymer pinylbenzene first with a bead-like body, and then bead surface grafted amines in. In this way, the beads produced polyamine - polyacrylate block copolymer resin. The design process, but also try to consider a low-cost, high-performance, low pollution, the idea for the workshop can be recycled more reasonable design, and rendering the process flow diagram and workshop floorplan.
Key Words: Block copolymer; adsorption resin; suspension polymerization; production process design
