The structure of IC with wood and its constitutes was also studied by Fourier Transform Infrared Spectroscopy. It shows that the reaction of IC with lignin mainly produces carbamate, when lignin contains some water, produces weak carbamide; but the reaction of IC with wood powder produces weak carbamite, and with the wood powder containing water mainly produces carbimide.

对于异氰酸酯与木材及其组分反应产物的结构，论文采用傅利叶红外谱图进行了分析，结果表明，木素与异氰酸酯反应主要生成氨基甲酸酯，含水率较低时有少量取代脲产生；木粉与异氰酸酯反应生成的氨基甲酸酯较少，含水木粉与异氰酸酯主要生成取代脲。
