摘要:
为提高水性聚氨酯整理棉织物的疏水性,采用侧链型聚二甲基硅氧烷与硅烷偶联剂KH550制备交联型水性有机硅改性聚氨酯(WSPU)乳液,然后将疏水二氧化硅(SiO 2)粒子的分散液喷涂在经WSPU浸轧整理的棉织物表面,制备得到基于WSPU/SiO 2的超疏水棉织物。考察KH550的质量分数对WSPU乳液烘干后所得乳胶膜性能的影响,探讨了WSPU与SiO 2复合整理棉织物的结构与性能之间的关系。结果表明:当KH550的质量分数为3.0%时,WSPU乳胶膜具有良好的机械性能与疏水性。当SiO 2分散液的质量分数为1.0%时,WSPU与SiO 2复合整理后的棉织物表面富集硅元素且具有微纳复合结构,织物水接触角达151.8°,滚动角为4.8°,呈现较好的自清洁性能与抗黏附性能;由于复合涂层与纤维间存在物理作用及化学键合,WSPU与SiO 2复合整理棉织物具有优异的耐水洗牢度,经20次水洗后水接触角仅下降3.0°。该研究为制备性能稳定的超疏水织物提供了参考。
