北京理工大学珠海学院2020届本科生毕业设计AbstractThis design is a production process design for an epoxy acrylate with an annualoutput of 1,000 tons of UV coatings.According to the data analysis,one-step methodis used to prepare epoxy resin,and the bulk method is used to produce TPGDA.Theepoxy resin and acrylic acid ring-opening reaction to generate epoxy Acrylateoligomer,then add TPGDA to stir and finally get the product.At the same time,thedevelopment status and development prospects of epoxy acrylates at home and abroadare reviewed.The raw materials,production equipment and polymerization methodsin the process are selected;the materials and heat in the production process areweighed;and the equipment selection calculation is based on Calculate the results andselect the appropriate equipment to put into production;draw the production processflow chart;draw the material balance diagram;draw the workshop layout;draw theworkshop layout;draw the profile of the polymerization reactor.After analyzing and calculating the actual polymerization situation,the best ratiowas obtained.The feed rate of bisphenol A was 896.31kg /B,the feed rate ofepichlorohydrin was 363.26kg/B,and the feed rate of 30%sodium hydroxidesolution was 1702.23kg./B,the dosage of 96%benzene is 67.5kg/B,the dosage ofdipropylene glycol is 230.05kg/B,the dosage of acrylic acid is 303.57kg/B,thedosage of 10%sodium hydroxide solution is 989.9kg/B,The dosage of 10%sodiumchloride is 1435.4kg/B,the dosage of epoxy resin is 379.61kg/B,the dosage ofTPGDA is 150.06kg/B;the final product is 750.3kg /B.Two batches of eachmaterial per day;330d(24h /d)work throughout the year;draw process flow chart,select the best equipment model through the amount of raw material input,polypropylene vertical storage tank,centrifugal pump,enamel reactor,turbo obliqueLeaf stirring paddle,water-cooled explosion-proof solvent recovery machine.Draw afloor plan of the workshop layout.Through calculation,the workshop plant covers anarea of 136 square meters.The cost of raw materials,hydropower and equipment iscalculated.The annual production cost is 49573703.4 yuan,and the unit cost is49.6yuan/kg,which is 49573.8 yuan ton.It is 70 yuan/kg or 70,000 yuan tonKey words:Epoxy resin;acrylate;epoxy acrylate;TPGDA;synthesis
