一种阴离子-非离子型水性聚氨酯的合成与性能研究
|
摘要
通过在合成聚氨酯时引入一种自制的含非离子性亲水基团的二元醇参与扩链,制备出了一种阴离子-非离子混合型水性聚氨酯,提高了水性聚氨酯在p H=6~7弱酸溶液下的稀释分散性,使其能够稳定应用于弱酸性的纺织浆料中;进一步通过乙二胺扩链后提高了聚氨酯成膜物的耐磨性与硬度,其磨耗仅为0.23 g/100 r,该水性聚氨酯能够在纺织浆料中替换目前广泛使用的聚乙烯醇。
An anionic-nonionic composite waterborne polyurethane has been prepared by the synthesis of polyurethane using a self-made diatomic alcohol having a nonionic hydrophilic group as chain extender. The prepared polyurethane is improved in terms of dispersibility in weak acid solution(p H=6~7) and can be applied stably in textile size with weak acidic property. In addition,the wear resistance and hardness of polyurethane film are improved by chain extender of ethylenediamine, and its abrasion is only 0.23 g/100 r. The waterborne polyurethane can replace the widely used PVA in the textile size.
