摘　　要：采用3种典型的脲醛(UF)树脂合成方法合成UF树脂,并对合成UF树脂的性能、化学构造、胶接性能、甲醛释放量及其固化历程进行了研究。揭示了UF树脂化学构造与合成方法、胶接性能、固化特性及甲醛释放量之间的相关关系,证明UF树脂的胶接性能、固化历程、甲醛释放量与UF树脂的化学构造直接相关,尤其是树脂中羟甲基含量与结合方式、亚甲基的构造对树脂性能影响最大。The paper discussed the properties, chemical structures, bonding performances, formaldehyde emission and curing mechanism of urea-formaldehyde (UF) resins by three typical synthetic technologies. It revealed the straight relations of urea-formaldehyde resin chemical structures with their bonding performances, formaldehyde emission and curing characters. Especially, the properties of UF resin are greatly affected by the content of hydroxyl methyl group and structure of methylene and hydroxyl methyl group.
