年产2000吨高温抗氧化环氧树脂的合成工艺设计

AbstractDue to its outstanding and stable thermal conductivity,mechanical function,low costof finished products,simple molding process,suitable for large-scale production,andrelatively high reliability,epoxy resin industry has developed rapidly in the past 10years.However,due to the increased crosslinking density of epoxy resin after reactioncuring,the epoxy resin has some disadvantages such as brittleness,poor heat resistanceand impact resistance,which make its practical application limited to some extent.Hightemperature oxidation resistant epoxy resin refers to those who add filler,improve theepoxy resin itself and the choice of curing agent to make the epoxy resin has the ability ofoxidation in the high temperature environment.High temperature oxidation -resistantepoxy resin is the most widely used engineering materials.In the design,the annual out of 2,000 tons of high-temperature antioxidant epoxyresin synthesis design,the production status,current market demand as soon asdevelopment of epoxy resin current analysis and prediction.Then based on the currentwidespread use of high temperature oxidation resistance of epoxy resin process route andmethods of production were analyzed,describes the production of high temperatureoxidation resistance of bisphenol A type epoxy resin production process,productionprinciple,raw material formula and process conditions,etc.Draw a process flow chart withcontrol the current points according to theoretical process route of the design summarizedby referring to the data,note the key points to be paid attention to in the process andpossible solutions to current problems in the design drawing.Then in the process of rawmaterial in and out of the material balance,to make the epoxy resin has the ability ofoxidation in the high temperature the heat balance of each reaction kettle,according to theformula listed a clear material balance sheet and the heat balance sheet.According to thedata in the kettle body selection and stirring device selection.Combined with all theconditions of the design in accordance with the provisions of safety production of the plantfloor drawings,drawing the layout of the floor plan and section.Consideration is also givento the design of three waste sources and treatments,including waste gas treatment,wastewater treatment and waste residue current treatment.Finally,the total investment cost ofthe site equipment,labor remuneration and materials needed in the whole productionprocess is preliminarily calculated and the annual profit is estimated.Keywords:High temperature antioxidant epoxy resin;production technology;material balance;equipment
