| 摘 要： | 利用单油酸三羟甲基丙烷酯(TMPM)、异佛尔酮二异氰酸酯(IPDI)和聚氧化丙烯(PPG)等制备水性聚氨酯。采用透射电镜(TEM)、动态激光光散射(DLLS)、红外光谱(FT-IR)、热重分析(TGA)和表面张力仪表征了乳液胶束形态、产物结构及性能。结果表明:水性聚氨酯(PU)分子上引入脂肪侧链容易在水中形成规整的胶束,但TMPM改性的水性聚氨酯胶束粒径随TMPM含量的增加不断增大,当w(TMPM)=0.07时,乳液不稳定;脂肪侧链的引入降低了水性聚氨酯乳液的表面张力,表面张力随着反应体系中—NCO和—OH摩尔比的增大而降低,随交联度的增大先增加后减小;TMPM的引入可以提高胶膜的热稳定性。

| Abstract: | Waterborne polyurethane was successfully synthesized by trimethylol propane monooleate(TMPM),isophorone diisocyanate(IPDI),polypropylene glycol(PPG) and so on.TEM,DLLS,FT-IR,TGA and surface tensiometer were applied to characterize both the morphology of the micelle and the structure and properties of the samples.Results show that waterborne polyurethane is successfully synthesized with long aliphatic chains which made it easier to form regulative micelles;and the particle size(increase) with the increasing ... |
