| 摘 要： | 以聚醚，甲苯二异氰酸酯为基材，二乙烯三胺为亲水单体，冰醋酸为成盐试剂，合成了自乳化型聚氨酯水乳液，并对溶剂的选择，乳液的粒径，流变性及稳定性进行了研究。结果表明随着中和度的增加，乳液粒径逐渐减小，而乳液的本征粘度则随中和度的增大而增大，所合成的乳液呈假塑性流体，而且很稳定。通过试验，我们选择了酮类作溶剂。

| Abstract: | A Series of self-emulsifiable polyurethane emulsions was synthesized, using polyether, TDI as monomers, TDA as chain extender, aqueous acid as neutral agent. The partical-size, flowing property, stability of emulsions and selections of solvent were studied. The results showed that partical-size was decreased with increasing the degree of neutralization, but viscosity was increased, ketone was selected as solvent according to, our experiment. |

| Keywords: | polyurathane emulsion degree of neutralization flowing property partical size viscosity. |
