Description
一、技术领域
本发明属于改性聚氨酯材料领域,具体涉及一种端氟烷基超支化聚氨酯乳液的制备方法。
二、背景技术:
聚氨酯材料具有很多良好的力学、粘附性、成膜性、柔韧性等性能;而溶剂型聚氨酯,由于含有大量有机溶剂,限制了其应用范围。水性聚氨酯不仅降低了有机溶剂的用量,还保持了聚氨酯优异的综合性能。但是亲水性扩链剂的引入,使得聚氨酯的耐水性变差。
含氟聚合物具有较低的表面能、高耐热稳定性以及优良的耐化学性,应用于基质上会增加材料的疏水性。据研究,结构不同的含氟聚合物,如无规、核壳、嵌段、接枝及超支化等均可用于基质防水防污。但无规结构具有随机性,不利于含氟基团的表迁,在具体应用时需加大含氟单体的用量才能得到较好疏水性能。目前,有机氟改性聚氨酯的研究已有报道,主要存在的问题是氟用量太大,使得成本居高不下。
三、发明内容
本发明提供了一种端氟烷基超支化聚氨酯乳液的制备方法,在保证优良疏水性能的前提下有效地降低了含氟单体的用量,极大降低了制备成本。
为实现上述目的,本发明采用的技术方案为:一种端氟烷基超支化聚氨酯乳液的制备方法,其特征在于:所述方法包括以下步骤:
1)端羟基超支化聚酯的合成:将中心核三羟甲基丙烷与AB2单体2,2-二羟甲基丙酸以1:3、1:9或1:21的摩尔比溶于N,N-二甲基甲酰胺,加入中心核与AB2单体总质量1~2%的对甲苯磺酸为催化剂,在N2保护下,升温至130~150℃,搅拌反应3~5h,减压除去反应生成的水,分别制得1代,2代,3代端羟基超支化聚酯;
