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. |
