| 摘 要： | 以甲苯二异氰酸酯(TDI)、嵌段聚醚二醇PE6100以及聚醚胺ED-2003为原料,采用自乳化法合成了固含量40%的非离子型水性聚氨酯(WPU),通过红外光谱(FT-IR)对产物的结构进行了分析,并对产物的粒径、流变性能、表面张力、临界胶束浓度(CMC)进行了研究,结果表明,得到的WPU具有一定的触变性,平均粒径大多为100nm~400nm,在1g/L的浓度时水溶液的表面张力不超过37mN/m,具有较好的降低水溶液表面张力的能力。

| Abstract: | Using toluene diiosocynate(TDI),polyether glycol PE6100 and polyetheramine ED-2003 as raw materials,a kind of nonionic water-borne polyurethane emulsions (WPU) was synthesized by the acetone method with solid content about 40%.Their structures were characterized by Fourier transform infrared spectrum analysis.The particle size,viscosity and surface activity,including surface tension,critical micelle concentration(CMC) in the aqueous solution were investigated.The results show that these water-borne polyurethane emulsions with particle sizes between 100nm and 400nm exhibit rheology behavior and excellent surface activity,most surface tension of these emulsions is less than 37 mN/m at concentration of 1 g/L. |
