| 摘 要： | 以二羟甲基丙酸（DMPA）、双丙酮丙烯酰胺（DAAM）为功能性单体，以丙烯酸酯类为溶剂合成了水性丙烯酸酯聚氨酯(PUA)复合乳液，成功的解决了以丙酮为溶剂制备水性聚氨酯造成的VOC含量高、工艺复杂、浪费能源的问题。通过红外(FT-IR)、透射电镜(TEM)等测试手段及吸水率、耐溶剂性、硬度、凝胶含量的测定，考察了丙烯酸酯聚氨酯复合乳液（PUA）及其涂膜的结构与性能，结果表明PUA复合乳液涂膜硬度达到3H，凝胶含量可达到84.3%，且耐水性、耐溶剂性得到明显提高。

| Abstract: | The PUA emulsion was synthesized in acrylate using DMPA, DAAM as functional monomer. The problem was successful solved using acetone as solvent preparation waterborne polyurethane. The VOC content is reduced and the energy was saved. Through means of FT-IR, TEM and measurement of water absorption test, solvent resistance, hardness and gel content, we had studied the structure and properties of the PUA emul-sion and coating. The results showed that the hardness of the PUA emulsion coating reached 3H, the gel content could reach 84.3 % and water resistance, solvent resistance has been markedly improved. |
