| 中文摘要: |
| 对片层结构的蒙脱土（MMT）进行表面改性，由改性的有机蒙脱土（OMMT）对低蛋白天然橡胶（LPNR）进行补强，采用机械混炼法制备LPNR/OMMT复合材料，研究OMMT对LPNR/OMMT复合材料性能的影响。结果表明：MMT适合采用双十八烷基二甲基氯化铵改性；随着OMMT用量增大，LPNR/OMMT复合材料的交联网络结构、物理性能、抗压缩永久变形性能和耐老化性能明显改善；当OMMT用量为8份时，复合材料的综合性能最佳。OMMT对LPNR的补强研究可以为改善LPNR的性能提供参考，有助于扩大LPNR的应用领域。 |
| 英文摘要: |
| The montmorillonite（MMT）was modified by surfactant and organic montmorillonite（OMMT） was obtained. Low protein natural rubber（LPNR） was reinforced by OMMT，LPNR/OMMT composites were prepared by mechanical mixing method. The effects of OMMT on the properties of LPNR/OMMT composites were studied. The results showed that，di-octadecyl dimethyl ammonium chloride was suitable for the modification of MMT. With the amount of OMMT increasing，the cross-linked network structure，physical properties，compression resistance and aging resistance of LPNR/OMMT composites were greatly improved. When the amount of OMMT was 8 phr，the performance of the composite was the best. This research work on the reinforcing effect of OMMT on LPNR could provide a reference for performance improvement of LPNR and help to expand the application field of LPNR. |
