年产1500吨水性金属烤漆用环氧丙烯酸酯的生产工艺设计

Production process design of 1500 tons per year epoxy acrylate forwaterborne metal baking paintAbstractThis design is a production process design for the production of 1500 tons of epoxyacrylates for waterborne metal baking paints.After consulting the information and literature,astep-by-step ring-opening reaction is used to generate single fatty acid epoxy esters and singlefatty acid epoxy acrylates,followed by the use of free radicals.Solution polymerizationmethod was used to produce water-based epoxy-acrylic hybrid resin,and the developmentstatus and development prospect of the water-based metal baking paint were summarizedSelect;balance the materials and heat produced;and select and calculate the equipment,andselect the appropriate equipment to put into production according to the calculation results;draw the production process flow chart,material flow chart,workshop layout drawing,plantlayout drawing and reaction Kettle profile.After analyzing the actual polymerization situation,a single fatty acid epoxy acrylatewas prepared by a step-by-step ring-opening method,and copolymerized with monomeracrylic acid,methyl methacrylate,n-butyl acrylate to obtain the target product,according tothe best industry Mixing ratio,added linoleic acid:acrylic acid =1:1,intermediate:acrylicacid:methyl methacrylate:n-butyl acrylate =1:5:5:5.Through calculation,each batch ofmaterials is fed into 4 batches per day and works 300 days a year.E-12 epoxy resin dosage is471.21kg/B,linoleic acid dosage is 110.63kg/B,acrylic acid dosage is 171.78kg/B,methylmethacrylate dosage is 198.89kg /B,n-butyl acrylate The feeding amount of ester is 254.62kg /B,the feeding amount of DMEA is 168.23 kg /B,and the feeding amount of xylene is59.41 kg/B.Draw the process flow chart,select the optimal equipment selection through theamount of raw materials,FRP vertical storage tanks:E-12 epoxy resin tank (HG-1200),linoleic acid tank (HG-800),acrylic tank (HG-500 and HG-800),methyl methacrylate tank(HG-800),n-butyl acrylate tank (HG1-1000),DMEA tank (HG-800),xylene tank (HG500),centrifugal pump (ISW80-100(I)A),stainless steel reactor:R101 (1000L),R102 (1000L),
