| 摘 要： | 采用低摩尔比合成工艺的脲醛树脂胶产生糊化现象，原因在于加成反应阶段，因介质ｐＨ值低，生成了亚甲基脲不溶物，羟甲基化不能充分，它表明此次树脂胜的合成是失败的。

| Abstract: | The paste formation of UF resin adhesive with low formaldehyde/urea molar ratio indicates the synthesis failure of the resin. This is due to that the first stage of the additive reaction takes place at low pH value,produces insoluble methyleneureas and results in insufficient methylolation. |
