| 摘 要： | 采用丙酮回流法合成水性聚氨酯。发现，在1，4-丁二醇（BDO）质量分数为5％-15％时，乳化状况较好；二羟甲基丙酸（DMPA）质量分数为5％-7％时，较易乳化；丙酮质量分数为50％时，可得到均匀稳定的浊液。同时，考察了成盐剂三乙胺和丁胺对乳液的影响，以三乙胺（TEA）为成盐剂时乳化效果较好。

| Abstract: | The waterborne polyurethane emulsion was synthesized by acetone reflux method. It was found that emulsification was fairly completed when the amount of BDO mass fraction was 5% to 15% and DMPA was 5% to 7%. Stable homogeneous emulsion was obtained with 50% of acetone. The influence of TEA and butylamine on emulsification was also examined at the same time and TEA ap- peared to have better effect. |
