| 摘 要： | 将生物乙醇木质素与自合成的聚酰胺多胺环氧氯丙烷(PAE)树脂进行接枝共聚改性大豆蛋白,制备环保型胶合板用胶黏剂,并通过单因素试验确定了木质素种类、木质素与PAE质量比、木质素与PAE树脂反应时间、大豆蛋白添加量等工艺条件对大豆蛋白胶黏剂胶合强度的影响。结果表明:当选用生物乙醇木质素与PAE进行接枝共聚、木质素与PAE质量配比为1∶4、反应时间为30 min、大豆蛋白添加量为50%(以木质素-PAE总质量而言)时,制得的三层胶合板湿胶合强度(1.03 MPa)可达到GB/T 9846—2015Ι类杨木胶合板的指标要求。

| Abstract: | The bioethanol lignin and self-synthesized polyamide polyamine epichlorohydrin(PAE) resin were grafted and copolymerized to modify soy protein to prepare an environmentally friendly adhesive for plywood. The effects of lignin type, mass ratio of lignin and PAE, reaction time of lignin and PAE resin, and soybean protein addition on the bonding strength of soybean protein adhesive were determined by single factor experiments. The results showed that bioethanol lignin and PAE were used for graft copolymerization, the mass ratio of lignin to PAE was 1∶4, the reaction time was 30 min, and the amount of soybean protein added was 50%(based on the total mass of lignin-PAE),the wet glue strength(1.03 MPa) of the three-layer plywood can reach the index requirements of GB/T 9846-2015 class Ⅰ poplar plywood after boiling water test. |
