Annual output of 30,000 tons of amino resinAbstractMethyl etherified amino resin is one of the big families of amino resins.It is anamino resin synthesized from methanol,formaldehyde and melamine by a specialprocess.They dissolve in water.These can be combined with water-based alkydresins and acrylic resins to form water-based coatings.Coatings.After crosslinkingand curing,the film has a good balance of hardness and flexibility.Products aremainly used in coil coatings and general coatings..Compared with butyl etherifiedamino resin,it has less pollution to the environment.Low viscosity,high solid content,low molecular weight and water soluble monomer resin can be miscible with theresin.The goal is to produce 30,000 tons of methylated amino resin per year.Weintroduced the basic properties,chemical properties,appearance and applications ofmethylated amino resins..Then,simply analyze and predict your current productionstate,market demand and supply.Finally,some Suggestions are put forward toimprove the resin technology and product performance.Secondly,through thecomparison and analysis of the process route and preparation method of methylatedamino resin currently used,the two-step synthesis method was selected,and thepreparation method,reaction mechanism,raw material formula and processconditions were described.According to the process route,the process flow chart withcontrol points is drawn,and the factors affecting the process are put forward.At thesame time,the scientific calculation process of material balance,thermal balance andequipment selection lists the material balance sheet and thermal balance sheet.Theequipment process calculation includes the design of kettle body,agitator and heattransfer.By combining the calculated results with the calculated results,a reasonablelayout of the workplace,including the layout of the workplace and the layout of theworkshop equipment,is designed,and the layout of the workplace is drawn on thefloor plan and cross section.Finally,the total investment cost of various productionequipment and workshops is preliminarily calculated,and three waste gas treatmentmethods are designed,including waste gas treatment,waste water treatment and waste
