摘　　要：以聚醚210(N210),IPDI(异佛尔酮二异氰酸酯)为基本单体,用硬脂酸单甘油酯封端,合成了一种表面能达33mN/m的低表面能水性聚氨酯树脂,并研究了硬脂酸单甘油酯用量、n(-NCO)/n(-OH)对树脂表面能的影响。Because of the high surface energy, water-borne PU can not wet the substrate of low surface energy well. In this experiment, we have synthesized a water-borne PU with low surface energy of 33mN/m, untilizing polyether 210（N210） and IPDI （isophorone diisocyanate） as basic monomers and glyceryl monostearate as blocking agent. Also we study the influence of the amount of glyceryl monostearate and n（-NCO）/n（-OH） ratio on surface energy of the resin.
