| 摘要: |
| 通过熔融插层的方式,将淀粉、豆渣分别与 4 种不同有机改性的蒙脱土( I. 28E,I. 30P,I. 34TCN,I. 44P)混合,采用双螺杆挤出机挤出发泡。 对复合材料的微观结构、膨胀率、表观密度、吸水率以及压缩强度进行了分析。 结果表明:添加有机蒙脱土能使复合材料的综合性能发生显著变化,其中添加 I. 34TCN 的复合发泡材料的泡孔直径最小,泡孔密度高,泡孔分散均匀,且膨胀率最大,表观密度最小,吸水率最低,压缩强度最高,在 4种不同有机改性蒙脱土的纳米复合材料中,I. 34TCN 的复合材料的综合性能最佳。 |

| Abstract: |
| Starch, soybean residue, and four different organically modified montmorillonite ( I. 28E,I. 30P,I. 34TCN, I. 44P) were used to produced foams by melt-intercalation, using a twin-screw extruder. The microstructure, expansion rate, apparent density, water absorption rate, and compressive strength of the material were investigated. The results indicated that overall performance of the composite foams is influenced dramatically by the addition of different organoclay; the I. 34TCN achieves the least cell size, highest cell population, best uniform dispersion and, the largest expansion ratio, least apparent density, lowest water absorption rate and highest compressive strength; among the four composite foams, the overall performance of the material by adding I. 34TCN is the best. |
