| 摘 要： | 研究了纯煤矸石粉及用表面活性剂处理或加入界面改性剂的煤矸石粉对两种聚丙烯(PP)的力学性能及加工流动性能的影响。结果表明：随着煤矸石粉用量的增加，PP填充复合材料的拉伸断裂伸长率和冲击强度下降．但拉伸屈服强度和加工流动性变化不大；煤矸石粉经硬脂酸处理后对复合材料的断裂伸长率、冲击韧性及加工性能有一定的改善作用；马来酸酐接枝聚丙烯能够明显提高复合材料的拉伸强度和冲击韧性。

| Abstract: | The effects of coal gangue powder and the powder treated with interfacial modifier on the mechanical and processing performances of two types of polypropylene were investigated. The results showed with the increase of the content of the coal gangue powder, the tensile elongation at break and impact strength decreased while the tensile yield strength and MFR changed little;the use of stearic acid in the treatment of the coal gangue powder could improve the elongation at break, impact strength and processability of the composite. The tensile strength and impact strength of the use of MAH-g-PP. |
