摘要
以甲苯二异氰酸酯(TDI)、聚醚(N210)、二羟甲基丙酸(DMPA)为基本原料,在无溶剂的条件下,利用侧链和直链氨基硅油通过合成和扩链两种不同的方法改性水性聚氨酯,制得了具有不同含量有机硅改性的水性聚氨酯乳液,并对涂膜的吸水率、力学性能、表面疏水性和微观形态等进行了系统的研究,并以此乳液为基料制得了相应的水性聚氨酯涂料。
Without the presence of organic solvent,a series of waterborne polyurethane (WPU) emulsions modified withAEAPS and ATPS were prepared by using extended and synthesized methods, based on 2,4-toluene diisocyanate (TDI),polyether (N210) and dimethylolpropionic acid (DMPA). The properties of the WPU films on water absorption, mechanicalproperties, surface hydrophobic properties and microphase conformation etc. were investigated.
