| 摘 要： | 用模压的方法制备了甲基丙烯酸缩水甘油酯(GMA)改性大豆分离蛋白质(SPI)塑料,探讨了GMA含量对SPI塑料的力学性能和耐水性的影响,并采用TG、SEM对SPI塑料和GMA改性SPI塑料进行了表征。结果表明:少量GMA可以对SPI塑料起到增强、增韧作用,并可提高其耐水性;加入少量的GMA可以提高SPI塑料的热稳定性;少量GMA改性SPI塑料能形成性能良好的柔性链结构,这种结构能明显提高SPI塑料的断裂伸长率。

| Abstract: | Glycidyl Methacrylate(GMA) modified Soy Protein Isolate(SPI) plastics were prepared via molding method.The effect of GMA content on the tensile properties and water resistance were discussed.The thermal properties,structure,and morphology of the molded SPI plastics,GMA modified SPI plastics were analyzed by Thermogravimetry and Scanning electron microscope.TG analysis indicate that addition of a small amount of GMA can improve the thermal stability of SPI plastics.SEM analysis shows that flexible chain form... |
