摘要
针对大豆蛋白塑料力学性能较差的问题,采用化学、填充的方法制备大豆蛋白与亚麻复合材料。通过扫描电子显微镜、电子万能试验机、熔体流动速率仪等实验仪器研究复合材料的形态结构、力学性能和流变性能,并测定了复合材料吸水率。研究结果表明,添加亚麻纤维对大豆蛋白的增强增韧效果都比较显著,硬度和拉伸强度对比纯大豆蛋白材料有了很大的提高,并且得到了大豆蛋白/亚麻复合材料的最佳用量,当亚麻的用量为6份时,复合材料的拉伸强度和硬度达到最佳,复合材料吸水率也较改性前有了很大的改善。
The Soy protein （SPI）/flax fiber （FF） composite was prepared by chemical and filling methods for to improve the mechanical properties of SPI. The systems of composite material were characterized by scanning electron microscopy （SEM）, electronic universal testing machine and melt index test instrument. The results showed that the tensile strength and hardness of soy protein increased by adding flax fiber and get the best content of flax. When the content of flax was 6 phr, the composite materials of soy protein has the highest tensile strength and its hardness achieves the best value. Water absorption of the composite materials of soy protein decreases definitely comparing with pure soy protein materials. Melt viscosity is significantly improved.
