| 摘 要： | 以异佛尔酮二异氰酸酯(IPDI)、聚醚多元醇2020、聚醚多元醇3050、酒石酸和环氧树脂E-44为主要原料,合成了内交联改性的聚醚型脂肪族水性聚氨酯(WPU)乳液,讨论了影响乳液稳定性及胶膜力学性能的因素。结果表明,当环氧树脂质量分数在4.0%～6.0%、nNCO∶nOH摩尔比在4.2～4.4、酒石酸质量分数在2.0%～2.2%、聚醚多元醇质量比m2020/m3050在为2.0～2.2之间时,可得耐水性、稳定性、力学性能优良的改性WPU乳液。

| Abstract: | A networking waterborne polyurethane emulsion was synthesizd with isophorone disocyanate(IPDI),polyether polyols(2020,3050),epoxy resin E-44, tartaric acid, etc.The influential factors on stability and mechanical properties of the waterborne polyurethane emulsion were discussed. The results showed that when the amount of E-44 was 4.0%~6.0%, nNCO/nOHwas 4.2~4.4, the mass percentage of tartaric acid was 2.0%~2.2%,mass ratio of polyether polyols m2020/m3050 was 2.0~2.2, the modified WPU with good water-resistance,stability and mechanical properties could be prepared. |
