摘　　要：对脲醛树脂的理论研究及其在木材工业中的实际应用进行了较全面的概括和评述。在将核磁共振应用于脲醛树脂的结构研究之后,区分了结构上的细微差别。讨论了脲醛树脂的合成过程,特别是酸性缩聚阶段的工艺条件对树脂甲醛释放量的影响。列举了脲醛树脂常用的各种改性物质及它们对脲醛树脂各种性能的改性效果。The theoretical researches on urea-formaldehyde resin and its practice in wood industry were reviewed in detail. With application of nuclear magnetic resonance in strueture researching of urea-formaldehyde resin, minor structural differences can be clearly distinguished. Effects of reaction condition in urea-formaldehyde resin production, especially during the acid stage, on the formaldehyde emission were discussed. Modes of modification of urea-formaldehyde resin were listed. Their properties after modification were also studied.
