摘　　要：本文研究并制备了聚氨酯型金属铬(Ⅲ)络合物微乳液。优选了复配乳化剂的种类、配比及助表面活性剂的种类;讨论了复配乳化剂和助表面活性剂的用量对乳液稳定性与粒径的影响。通过纳米粒度测定仪、透射电镜对最优条件下的微乳液进行了表征。In this paper, the microemulsion of polyurethane-chromium（ Ⅲ） complexes was prepared. The kind and ratio of the compound emulsifier and the kind of surfactant were concluded as well. Several factors that influence the stability and particle size of micro emulsion such as the content of compound emulsifier and surfactant were discussed. The main physical properties of the microemulsion were characterized by the methods of transmission electron microscope and laser nanoparticle detecter.
