Description

一种含短氟化烷基超疏水乳液的制备方法
技术领域
本发明属于超疏水涂层制备技术领域,具体涉及一种短氟化烷基超疏水乳液聚合制备超疏水涂层的方法。
背景技术
非润湿涂层由于其在自清洁、防冰、防污、抗粘接和耐腐蚀表面的潜在应用,成为当前材料科学的一个研究热点。许多研究致力于开发超疏水或超疏油表面,或者同时具有拒水拒油的全疏水表面。根据从自然中获得的灵感,将微观和纳米级的层次结构与低表面能材料(如氟化聚合物、硅烷、硫醇、表面活性剂、等离子体等)结合起来可以获得最佳效果。
超疏水涂料是一种具有特殊表面性质的新型涂料,是指固体涂膜的水接触角大于144°并且常指水接触角滞后小于4°,具有防水、防雾、防雪、防污染、抗粘连、抗氧化、防腐蚀和自清洁以及防止电流传导等重要特点,在科学研究和生产、生活等诸多领域中有极为广泛的应用前景。
氟原子由于其特殊的性能,可以在全氟碳化合物(PFCs)中构建一个非常有效的全疏水表面,所以常常在超疏水乳液中引入氟元素。但是较长碳链的含氟化合物稳定性比较好,难以自然降解,具有一定的生物累积性,因此对人类的健康和自然环境产生了潜在的严重威胁,这也使得全氟辛酸(PFOA)和全氟辛基磺酰类化合物(PFOS)在世界范围内禁用。
中国专利CN144733343A公开了一种高韧性疏油疏水涂料。采用特定比例的羟基丙烯酸树脂、纳米二氧化钛增强含氟疏水材料、聚醚酯、聚酯树脂作为成膜物料,使涂料具有优异的疏水疏油性能和韧性;其中,纳米二氧化钛增强含氟疏水材料的制备过程中,用硅烷偶联剂APS改性二氧化钛,能够改善二氧化钛在有机体系中的相容性和分散性,过程中将二氧化钛、硅烷偶联剂APS经第一次超声处理分散在甲苯中,在水浴的恒温中,硅烷偶联剂APS能够均匀地链接、包覆二氧化钛,大幅提高了涂料的表面疏水性能,有利于提涂料的强度和韧性;而选用的N-羟乙基全氟辛酰胺、甲基丙烯酸甲酯,在引发剂份过硫酸铵的作用下,能够快速、稳定地交联形成高分子聚合物,在施用后形成的涂膜中,发挥大幅降低表面张力的作用,具有优异的疏水、疏油性能,且耐热、耐候性良好。但是整个合成过程较为复杂,所用的含氟试剂对环境存在威胁。
中国专利CN146493391A公开了一种纳米粉末疏水疏油改性方法。将纳米粉末与环己烷或正丁醇混合,通过超声波分散仪处理得到均匀分散悬浮液。然后滴加全氟辛基三甲氧基硅烷或全氟癸基丙烯酸酯至上述的悬浮液中进行浸渍处理,最后进行喷雾干燥,得到改性后的氟化纳米粉末。虽然改性之后纳米粉末具有优异的疏水疏油性能,但是所用的含氟试剂具有长碳链对环境存在威胁。
目前,已有文献报道短碳链的含氟基团具有降解性,所以将其应用于超疏水乳液中既可以提供优秀的疏水性能,又符合绿色化学的理念。

在烧杯中加入12.4g丙烯酸丁酯、12.4g甲基丙烯酸甲酯,助稳定剂十六醇聚苯乙烯1.4g、交联剂乙二醇二丙烯酸酯1.4g、反应型乳化剂含烯丙基的特种醇醚硫酸盐(NRS-14)1.4g,4.1g引发剂过硫酸铵(APS)及164g水,冰浴条件下,在超声波细胞粉粹机中超声3s,间歇4s,持续14min。将所得的预乳液装入四口烧瓶中,氮气吹扫半小时,74℃反应12h,即得共聚物乳液。
2.疏水性能测试
将上述所得乳液用表面张力仪测试表面能,并将乳液用匀胶机喷涂在木材、钢板、玻璃、PVC板上测试接触角。
表1为本发明实施例1-6以及对比实施例中共聚物的分子量及分布、共聚物乳液的表面能及在玻璃、钢板、木材、PVC板上的接触角数据。从表中结果可以看出,添加了功能单体BRFAE之后,乳液的表面能降低,涂层疏水性能提高显著。
