摘　　要：用丙烯酸酯对水性聚氨酯 (PU)进行共混和共聚改性 ,并对改性效果进行了研究。结果表明 :同改性前的丙烯酸乳液 (PA)乳液及PU乳液相比 ,改性使乳液的粒径、粒子形态发生改变 ,使耐热性。Water borne polyurethane is modified with Acrylic ester by the ways of copolymerization and mechanical mixture, and the modifying effects are studied. The results show that the particle size and shape of copolymerization emulsion are greatly changed and thermodynamic stability, solvent resistance and adhesion power increase, compared with acrylic emulsion and PU emulsion.
