The coating based on polyester acrylate is more in line with the current green coating requirements, the curing rate is fast, and there is a broad market space. The design with an annual output of 1000 tons of UV coating polyester acrylate for the production process design. Firstly, the development of polyester acrylate at home and abroad is analyzed, and some Suggestions are put forward. Compared with the current production method, the two-step method is adopted to produce polyester acrylate by polycondensation addition reaction. The production mechanism, preparation method, formula design, equipment materials and so on are described. Identify the problems and solutions that should be addressed. Carry out material balance calculation, heat balance calculation and process equipment calculation rigorously, list the material balance and heat balance table, among which the equipment process calculation includes
