摘要
进行了几种聚酯/聚醚水性聚氨酯树脂的合成及力学性能、耐水性、耐溶剂性比较。并用丙烯酸酯及环氧树脂对水性聚氨酯进行改性,结果表明:两者均不仅可以提高聚氨酯的耐水性和耐溶剂性,而且也可提高聚氨酯的力学性能。其中,环氧树脂的改性效果尤为显著。
Study was made of the synthesis, mechanical property, water resistance, solvent resistance of several kinds of polyester/polyether PU. Waterborne PU was modified with acrylate and epoxy resin. The results showed that both of them could enhance not only water resistance and solvent resistance of PU but also its mechanical property. The modifying effects of epoxy resin on waterborne PU was even more remarkable.
