Synthesis and Properties of Waterborne Polyurethane Emulsions Using in Printing Ink

Abstract:

Taking polyether dihydroxy alcohol, toluene diisocyanate (TDI) and dimethylolpr- opionic acid (DMPA) as raw materials, aromatic polyether waterborne polyurethane emulsion was synthesized. And then the effects of isocyanate/macroglycol molar ratio(R value), amount of DMPA, neutral degree and temperature on the properties of emulsion such as appearance, viscosity, water absorption and stability were studied. The experimental results showed that when R value is 2~2.5, amount of DMPA used is 5.0%, reaction temperature is 80°C and neutral temperature is 40°C, the waterborne polyurethane emulsion synthesized meet the requirement of printing ink.
