摘　　要：本文通过红外光谱方法和螺线流动长度实验分析了酚醛树脂在增稠和储存过程中的结构变化和讨论了酚醛树脂的增稠和储存稳定性。Ca（OH）2／MgO对酚醛树脂的增稠主要是通过络合配位键的形式来实现的；B2O3／ZnO对酚醛树脂的增稠则主要是通过化学键的形成来实现的；酚醛树脂中引入羧基基团后提高了其增稠和储存稳定性。Structure change of phenolic resin during thickening and storage is given and thickening and storage stability of phenolic resin paste are discussed by infra-red spectrum analysis and spiral flowing experiment method.Analysis of the structure change of phenolic resin during thickening shows that B2O3molecules are linked to phenolic resin molecules by covalent bond and coordination bond. Phenolic resin with carboxylic group has excellent properties of thickening and storage stability
