: Water-based polyurethane acrylic composite emulsion is synthesized by two-step method. First of all, in the acetone solution through a gradual polymerization reaction synthesis of hydrophobritic groups of polyurethane, polyurethane and acrylic monomer mixed in reverse, obtained acrylic monomer pre-emulsion, and then the emulsion polymerization reaction, prepared a water-based polyurethane acrylic composite emulsion. The effects of DMPA and HPMA content on the stability of water-based polyurethane acrylic complex emulsions are discussed, and the final sample is indicated by laser light scattering-nanoparticle meter, gel permeation chromatography, transmission mirror, etc.
