摘　　要：木质素可以改性三聚氰胺甲醛树脂,尤其是采用含有羧基的木质素改性三聚氰胺甲醛树脂,且在甲醛与三聚氰胺的比值(摩尔比)均为5.0左右时,其反应条件温和,树脂的贮存稳定性比传统的木质素改性三聚氰胺甲醛树脂大大提高。上述树脂均可发泡,且以含有羧基的木质素改性三聚氰胺甲醛树脂的综合性能最好。这对开发新型的生物质泡沫材料提供了依据。Melamine formaldehyde resin can be modified by Lignin which containing carboxyl. When melamine and formaldehyde＇s ratio（molar ratio）was about 5, the reaction condition was mild, resin storage stability was greatly improved than the traditional lignin modified melamine formaldehyde resin. The resin can be expanded, and with lignin which contai- ning carboxyl modified the end resin had the best comprehensive performance. The basis was provided for the development of new biomass foam material .
