摘要： 采用碱焙烧法从粉煤灰中提取Al2O3，将提取的Al2O3用于聚丙烯（PP）改性研究，并以市售Al2O3改性的PP为参考，考察了Al2O3对PP力学性能、微观形态的影响。结果表明，提取的Al2O3改性PP的拉伸性能和冲击性能与市售Al2O3相当；当Al2O3含量增加到2 %时，PP的拉伸断面均由平整结构变为轻微的层状结构，此时拉伸和冲击性能达到最佳，拉伸强度提高约6 %、伸长率提高约23 %、冲击强度提高约14 %；当Al2O3含量继续增加到5 %时，层状结构更为明显，改性PP的冲击强度急剧下降。

Abstract: Al2O3 was extracted from fly ash via high-temperature alkali calcinations. The properties of PP containing such extracted Al2O3 were compared with commercial PP/Al2O3 resins. It showed that, the tensile and impact properties of PP/extracted Al2O3 were similar to commercial resins. When the content of the extracted Al2O3 increased to 2 %, the microstructure of PP matrix change from smooth structure to slight lamellar structure, and the tensile strength, elongation at break, and impact strength increased by 6 %, 23 %, and 14 %, respectively, based on neat PP. However, when the content of extracted Al2O3 increased to 5%, the impact strength of PP decreased dramatically.

Key words: Fly ash, aluminum oxide, polypropylene, modification
