Abstract: A process for preparing aqueous polyurethane solvent-free uses an acrylate monomer instead of acetone to dilute a prepared polyurethane prepolymer, not only the monomer can be added without cooling, but also the prepolymer has good dispersal and is favorable to subsequent dispersion in water while preventing coagulation and acetone residual; additionally, the invented process let the aqueous polyurethane become modified by acrylic grafting may improve the aqueous polyurethane being excellent in terms of mechanical strength, heat resistance and water resistance.
