A Design About The Production Process Of Water-dispersed Polyurethane Adhesive Modified By Organosilicon
Abstract: In this design, using polypropylene glycol(PPG),toluene diisocyanate(TDI)，dimethylolpropionic acid (DMAP)and Organosilicon as raw material, gradual addition method and acetone method modified water-dispersed polyurethane adhesive. Through this way WPU improving the water resistance, while keeping good mechanical properties. This design covered the determine of the technology program、the materials balance and the process calculation of the reaction kettle. A process diagram for water-dispersed polyurethane ahesive production and the reaction kettle、the workshop layout. Furthermore, a simple industry prospect analysis、a simple economical check、 the safety operation and the treatment method with “the three wastes (waste gas, waste water and industrial residue)” also included in this design.
Key words: Organosilicon, Water-dispersed polyurethane, Adhesive, Technology, Reaction kettle
