摘　　要：以聚四氢呋喃醚和异佛尔酮二异氰酸酯为原料,在预聚反应中引入二羟甲基丙酸亲水扩链荆,以三乙胺为中和剂,采用内乳化法合成了阴离子型水性聚氨酯皮革涂饰剂。研究了NCO/OH摩尔比、DMPA引入量、乙二胺用量、封端荆正丁醇用量和存放时间对涂饰剂及膜性能的影响。The anionic waterbased polyurethane for leather finishing was prepared from polytetrahydrofuran glycol (PTMG). isophorone diisocyanate( IPDI). dimethylol propionic acid (DMPA) and triethylamine by the internal emulsification. The effect of NCO/OH molar ratio, the fed amount of DMPA, ethylene diamine , n - butanol and storage period on properties of emulsion and film was studied.
