一种含超细羽绒纤维接枝纳米沸石微粉的水性聚氨酯涂层剂
技术领域
本发明涉及纺织品涂层整理剂技术领域，尤其涉及一种含超细羽绒纤维接枝纳米沸石微粉的水性聚氨酯涂层剂。
背景技术
纺织品涂层整理剂简称涂层剂，是一种涂布于织物表面的高分子化合物薄膜，用以改善织物的风格、手感以及外观等等，极大的提高了纺织品的附加价值。水性聚氨酯涂层剂是一类重要的环保涂层剂，其具有弹性优，手感柔软，耐磨耐溶剂等优点，然而其透湿性较差，严重影响织物的穿着体验，且生产成本高，随着市场需求的提升，研究防水透气类环保聚氨酯织物涂层剂显得尤为重要。《丝素/聚氨酯防水透湿涂层剂的制备及其应用》一文利用丝素对聚氨酯进行改性处理，有效的提高了涂层剂的透湿效果，然而丝素的疏水性较差，随着丝素质量分数的提高涂层膜的耐水性会变差，且丝素的生产成本较高，不利于大规模生产。
我国是羽绒生产大国，年产量遥遥领先于其他国家，羽绒是一种多基团的氨基酸肽链结构的天然蛋白质材料，粗蛋白含量占整个羽绒的80%以上，其结构蓬松柔软，保暖性卓越，具备良好的吸湿性和生物相容性，然而在其资源利用方面的研究利用依旧处于原材料粗加工的水平，除了少量的作为保暖填充材料用于服装和床上用品以外，还有一部分用于体育用品、工艺品以及复合材料的增强材料，大部分都被作为废弃物处理，造成了大量的资源浪费。羽绒在透湿透气性以及耐水性方面均优于丝素，如果能将羽绒有效的引入聚氨酯涂层剂中，将会获得具备优良综合性能的涂层剂，提高织物的经济价值。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种含超细羽绒纤维接枝纳米沸石微粉的水性聚氨酯涂层剂。

所述的超细羽绒纤维接枝纳米沸石微粉的制备方法为：
（1）将羽绒经过除杂、消毒、清洗、干燥后经高速剪切机剪切粉碎，过625-800目筛，随后将过筛物投入磨浆机内，以无水乙醇作为研磨介质磨浆，研磨2-5h后在60-80℃条件下干燥，制成超细羽绒纤维，最后将所得物料投入浓度为1-5%的戊二醛水溶液中浸泡处理1-3h，反应结束后过滤，物料水洗2-3次后干燥，制成戊二醛接枝的超细羽绒纤维；
（2）将纳米沸石投入pH值为4-6的酸溶液中浸泡处理10-15h，处理结束后加入二甲基酰胺，搅拌混合均匀后加入氨基硅烷偶联剂，继续搅拌混合反应5-10h，反应结束后投入步骤（1）所得的物料，混合均匀后加热至50-60℃，反应2-5h，反应结束后产物离心水洗后喷雾干燥即得所述的超细羽绒纤维接枝纳米沸石微粉。
所述的超细羽绒纤维与纳米沸石的重量比为0.5-1:1，所述的二甲基酰胺、氨基硅烷偶联剂、纳米沸石酸溶液的体积比为1:0.5：1-5。
所述的一种含超细羽绒纤维接枝纳米沸石微粉的水性聚氨酯涂层剂的制备方法为：将各原料搅拌混合均匀后即得。
本发明将羽绒纤维处理成具有高表面活性和高热稳定性的超细纤维，并将其与表面氨基化的纳米沸石在戊二醛作用下交联接枝，形成结构牢固的复合物，其分散在聚氨酯乳液中后，与聚氨酯的相容性好，干燥后的涂层具备发达的孔隙结构，透气性好，排湿快，还可提高织物的保暖性，同时沸石还具备独特的保健效果，从而极大的提高了织物的经济价值。
