| 摘 要： | 将淀粉进行糊化改性,将改性淀粉在乳液状态下与天然胶乳共混,制备淀粉/天然橡胶复合材料。利用扫描电镜(SEM)和热重分析(TG)表征复合材料的结构,并测定了其力学性能。研究结果表明:淀粉经糊化后,淀粉粒子在天然橡胶中分散均匀,粒径明显减小,复合材料的热稳定性和力学性能明显提高。

| Abstract: | Firstly starch was pasting,then coagulated with natural rubber latex to prepare the composite.Using SEM and TG,the structure and thermal stability of starch/NR composites were studied.Thus referring to the experimental results,after starch was pasted,the dispersion degree of starch particles in NR matrix was increased and particles dimension dramatically decreased,the thermal stability and mechanical properties of composite were obviously increased. |

| Keywords: | starch natural rubber(NR) composite thermal stability |
