摘　　要：钠基蒙脱土(Na-MMT)的加入,提高了大豆蛋白胶黏剂的预压性能、粘接强度和耐水性,当Na-MMT的加入量为大豆分离蛋白的1 wt%时,增强效果最好,可以使杨木胶合板的干强度和Ⅱ类湿强度分别提高20.5%和18.8%;利用XRD、TEM、FTIR、接触角等分析方法研究了Na-MMT增强豆胶耐水性的机理。The adhesion strength and water resistance of soy protein based adhesives were enhanced by adding Na-montmorillonite（Na-MMT）.The adhesion strength and water resistance were the highest when 1 wt%Na-MMT was added.The adhesion strength and type-Ⅱ wet strength of the poplar plywood were improved by 20.5%and 18.8%respectively.The water resistance mechanism of Na-MMT enhanced soy protein based adhesion was analyzed by using XRD,TEM,FTIR and contact angle.
