| 摘 要： | 研究了镁盐晶须(M—HOS)增强聚丙烯(PP)、聚烯烃弹性体(POE)增韧聚丙烯以及PP／M—HOS／POE三元复合材料的力学性能和结构形态。结果表明：M—HOS的加入可以显著提高PP的刚性，当M—HOS填充质量份数为10份时(PP=100份为基准)，体系的拉伸强度和冲击强度均达到最佳；POE的加入则可以显著提高PP的冲击强度，复合体系分别于常温下POE含量15份以及-20℃下POE含量40份时发生脆韧转变；在M-HOS用量为10份时，M—HOS对PP／POE共混体系具有协同增韧增强的作用。

Studies of the Toughness and Reinforcement of PP/Magnesium Hydrate Whisker/POE Composites |

| Abstract: | The mechanical properties and morphology of PP/Magn e sium hydrate whisker(M-HOS), PP/POE and PP/M-HOS/POE composites were investiga ted. The rigidity of PP increased with increasing amount of M-HOS. The PP/M-HO S system exhibited optima of both tensile and impact strengths at an M-HOS cont ent of 10 wt%. POE may improve the impact strength of PP and the brittle-ductil e transition at ambient and low temperatures occurred at POE contents of 15 wt% and 40 wt%, respectively. M-HOS and POE gave rise to a synergistic toughening e ffect for PP. |
