Method for preparing polyurethane-polyacrylic ester microemulsion
The invention discloses a method for preparing cation-type polyurethane-polyacrylic ester microemulsion which is organic-solvent-free and emulsifier-free. The method substitutes inert vinyl monomers for organic cosolvent used during the conventional polyurethane preparation, for purpose of obtaining polyurethane prepolymer by polymerizing isocyanate and polymer polyalcohol; then after temperaturereduction, neutralization and water dispersion, functional monomers with an appropriate amount are introduced; and then the polymerization of the vinyl monomers is further initiated under the action of water-soluble azo initiator so as to obtain the cation-type solvent-free polyurethane-polyacrylic ester compound microemulsion. The method completely eliminates the organic cosolvent added in conventional waterborne polyurethane, thereby achieving the true environment-friendliness. In the preparation process no emulsifier needs to be added; obtained product grains realize nanometer-level particle size and good performance; and through formula adjustment, the obtained product grains can be used both for waterbone coatings but also in the adhesive field.
