摘　　要：本文综述了国外近年来对新型合成胶粘剂（包括低毒性脲醛树脂胶粘剂，阻燃、防腐胶粘剂和异氰酸脂胶粘剂）、利用再生资源制各胶粘剂（包括木素、单宁和碳水化合物）和“非传统粘合”技术的研究进展。作者认为，今后发展趋势是对现有合成树脂胜粘荆进行改性并向高性能发展；开发原料来源丰富、成本低廉、性能更优的新型非甲醛系合成胶粘剂；充分利用再生资源制胶和开发“非传统粘合”技术。Abstract in this paper a review is made of the advances in research on new tylies ofsynthetic adhesives (low toxic UF ,fire-retardant and antiseptic adhesives and emulsionpolpoer isoyanate adhesives ) abroad in recent years. A general, picture is given of woodadhesives using renewable resources. After describins the preparation of tanin basedadhesives and adhesives using natural hydrncarbonates ,the paper focuses on the researchon lignin - based adhesives , including preparation of SSL , adhesives made of lisninsulfonate ,treatment with non-chemical method such as ultrafiltration, acceleration ofthe crosslinking curing of the lisnin adhesives by adding crosslinking agent or per-oxide, chemical modofication of lignin to promote the reaction activity, condensationcopollymerization of lisnin and phenol formaldehyde or mixture with phenol formalde-hyde resin,condensaton eopolpoerization of lisnin and urea formaldehyde or mixturewith urea formaldehyde. Abrief narration is given of the 'non-conventional adhesion'technique .
