摘要:
 以麻风树种子蛋白为原料，以三聚氰胺乙二醛（MG）树脂和环氧树脂（EPR）为交联剂，旨在为相关人造板产品尤其是胶合板制备另一种新型蛋白胶黏剂。采用红外光谱（FT-IR）、核磁共振碳谱（13C-NMR）、电喷雾电离质谱（ESI-MS）等分析其制备机理，同时通过检测蛋白胶胶合板性能，分析胶黏剂制备机理与实际应用之间的关系。结果表明，MG含有大量支链型的-NH-(CH)OH基团，与蛋白质的氨基等活性基团具有较好亲和性。环氧树脂与蛋白氨基反生反应，主要以N-1取代为主。单独以EPR或MG交联改性的蛋白胶不能同时满足Ⅰ、Ⅱ类胶合板强度要求。MG和EPR两者共同作为交联剂时，可以增加改性后麻风树种子蛋白胶黏剂的内聚强度和交联密度，使改性后蛋白胶同时满足Ⅰ、Ⅱ类胶合板胶接强度和耐水性能要求。综合改性后麻风树种子蛋白胶黏剂的制备成本和使用性能，4%三聚氰胺-乙二醛树脂+1%环氧树脂为最佳交联剂配方。
Abstract:
 In order to develop a new kind of protein-based adhesive for man-made board products and plywood especially,seed protein of Jatropha curcas was used as basic material,and melamine glyoxal resin (MG) and epoxy resin (EPR) as friendly cross-linkers.The modified mechanism of protein-based adhesives were characterized by FT-IR,13C-NMR and ESI-MS.The results indicated that MG contained many -NH-(CH)OH groups,which had a good affinity with the active groups of the proteins,such as amino group.The main products between epoxy resin and amino group in the protein were given priority to replacing amino N-1.Both MG and EPR as cross-linkers could improve the cohesion strength and crosslinking density,which contributed to the bonding strength and water resistance of plywoods-Ⅰ and plywoods-Ⅱ.Considering the cost and comprehensive performances,4% MG+1% EPR was the best combination for the preparation of Jatropha curcas seed protein-based adhesive.
