摘　　要：以异氰酸酯、聚醚多元醇为主要原料,以二羟甲基丙酸为亲水单体合成了一系列阴离子型水性聚氨酯分散液,并将其应用于织物整理剂、纸张光亮剂及鞋用胶粘剂上,取得了较好的效果。该文针对其不同的用途对水性聚氨酯的制备和应用工艺分别进行了探讨。实验结果表明,以不同分子质量的聚醚多元醇制备水性聚氨酯织物整理剂,可以达到不同的整理要求;调整反应过程中的NCO/OH比值,可以制备成膜性好,光泽度高的纸张光亮剂;以MDI制备的水性聚氨酯鞋用胶,剥离强度可达到100N·cm^(-1)。A series of anionic aqueous polyurethanes were prepared mainly from diisonynate, polyether polyol and dimethylol propionic acid used as hydrophilic monomer. They were used in fabric treatment agent, paper lighting agent and adhesive for shoemaking and got excellent performances. For different applications the paper discussed the preparation and application process of the aqueous polyurethanes. The different fabric treatment agents can be obtained by using the polyether polyol with different molecular weights; the excellent paper lighting agent can be prepared by adjusting the value of NCO/OH during reaction process;the aqueous shoemaking adhesive can be made from MDI and had the peel strength upto 100 N · cm-1.
