摘　　要：水性聚氨酯具有良好的物理力学性能和优良的耐寒性,已成为研究的热点。但是,由于单一的水性聚氨酯乳液存在自增稠性差、固含量低、乳胶膜的耐水性差、光泽性不佳等缺点,其应用受到一定的限制,需要用其他乳液改性,使共混复合乳液在性能上互补。本文介绍了物理共混和化学共混技术在水性聚氨酯上的应用及其研究概况。The study of waterborne polyurethane is now the hot research topic, because it has good mechanical properties and excellent cold tolerance. But just only single waterborne polyurethane has poor self-thickening, low solid content,and it＇s latex film has poor water resistance and poor luster. So its application subject to certain restrictions. Now we use other emulsions to improve the waterborne polyurethane emulsion to get the complementation in performance of blend composite emulsion. The application and research progress of physical and chemical blending technology in waterborne polyurethane were in the round introduced in this paper.
