采用熔融插层法，添加不同含量的蒙脱土，制备了淀粉/豆渣复合发泡缓冲材料，对所制备的复合材料进行了表征和研究。结果表明：蒙脱土质量分数(全文同)小于3%时材料的膨胀率差异较小，而大于3%后随着蒙脱土含量的增加，膨胀率会显著降低，且3%的材料表观密度最低；5%实验组的泡孔直径最小，泡孔均匀，且材料表面无较大的泡孔，其抗吸水效果也最好；添加蒙脱土能够较显著地增加复合材料的机械强度，其中5%实验组的压缩强度最高。在4种不同有机蒙脱土添加量中，5%的添加量的淀粉/豆渣复合材料的综合性能最好。

Starch/soybean residue composite foam cushioning material with montmorillonite contents were prepared by a melt-intercalation method. The characterization of the nano-composites was analyzed. The results showed that there is little difference on the expansion rate when montmorillonite content is lower than 3%; when montmorillonite content is above 3%, the expansion rate decreases remarkably with montmorillonite content; the apparent density of the composite with 3% montmorillonite content is lowest; the one with 5% content has the smallest cell diameter, has even cell distribution, and has good effect to resist to water absorption; addition of MMT can increase the mechanical strength of the composite dramatically and the 5% MMT content has the highest compressive strength; among the four MMT content nanocomposites, the 5% one has the highest comprehensive properties.
