摘要
研究了聚氨酯预聚体的合成以及香草醛封闭型聚氨酯乳液的制备,讨论了将其用于造纸湿部添加的最佳工艺,结果显示:经过聚氨酯化处理后,改善了纸张的物理性能。
In this study, waterborne polyurethane prepolymer and vanillic aldehyde blocked waterborne polyurethane were prepared. The vaniUic aldehyde blocked waterborne polyurethane was applied as wet end additive to improve the physical properties of finished paper. Its addition process was optimized.
