Keyword:  水性聚氨酯甲基丙烯酸十二氟庚酯改性耐水性能;
Abstract: 采用聚已二酸丁二醇酯(PBA)、异氟尔酮二异氰酸酯(IPDI)、二羟甲基丙酸(DMPA)、甲基丙烯酸十二氟庚酯(MBFA-12)等原料合成了含氟水性聚氨酯乳液(WPU-F),考察了MBFA-12的用量对WPU-F乳液的粒径与黏度,WPU-F胶膜的吸水率、接触角、附着力、硬度、拉伸强度、热力学性能等的影响.结果表明:用MBFA-12改性水性聚氨酯,在提高水性聚氨酯胶膜的拉伸强度、附着力、热力学性能的同时,由于侧链上密集的-CF3作用,接触角从70.7(°)增加到107.6(°),胶膜吸水率从61.3%降到15%以下,大大提高了聚氨酯的耐水性.
