纳米微粒对大豆蛋白胶粘剂性能的影响

摘要

The effects of nanoparticles on the shear strength, water resistance strength and antiseptic properties of soybean adhesives with soy protein isolated as raw materials were studied. Nano-TiO 2, nano-SiO2 and nano-Al2O3 can all enhances the shear strength, water resistance strength and antiseptic properties of soybean adhesive. The optimum shear strength and water resistance properties of soybean adhesive were obtained with adding 8% nano-Al2O3. And the optimum antiseptic properties of soybean adhesive were obtained with adding 8% nano-TiO2. The micro-morphology pattern of soybean protein based nano-composite adhesive was analyzed by SEM.%以大豆分离蛋白为原料，研究纳米微粒对大豆蛋白胶粘剂的干态胶接强度、耐水强度及防腐性能的影响。添加纳米TiO2、SiO2、Al2O3均可提高大豆蛋白胶粘剂的干态胶接强度、耐水强度及防腐性能，其中添加纳米Al2O3对提高胶接强度、耐水强度效果最好，最佳添加量为0.8%；添加纳米TiO2对提高防腐效果最好，最佳添加量为0.8%。并用扫描电镜分析了大豆蛋白基纳米复合胶粘剂的微观形貌。
