| 摘 要： | 聚醚—2000与TDI发生预聚反应，得到端基为—NCO的预聚体，然后加入阳离子亲水单体进行扩链反应，制得含有阳离子的预聚体，加入有机酸成盐后，乳化得蓝光微透明乳液。这种自乳化阳离子聚氨酯乳液，可使成革柔软、细致、手感好，且有良好的粘着性 。

| Abstract: | The - NCO terminated prepolymer was obtained from the prepolymerization reaction of diol polyether and 2, 4 - tolydiisocyanate, and extended with water affinity cationic monomers to prepare the prepolymer. And then organic acid was added into the above product, followed by the neutralization and slowly water addition to get the translucent emulsion with blue light. The self-emulsifying cationic polyurethane emulsion with good adhesion can impart leather softness, finess and good hands. |
