| 摘 要： | 将废弃石材加工过程中的副产物石粉引入到低密度聚乙烯(LDPE)中,实现对废弃石粉的回收利用。采用了差示扫描量热法(DSC)、广角X射线衍射(XRD)以及电子万能试验机研究了LDPE/石粉复合材料的结晶动力学、结晶形态以及力学性能。结果表明:石粉对于LDPE的结晶过程影响有限,复合材料与聚合物的结晶峰顶温度以及半峰宽相差无几;复合材料的结晶结构与结晶形态与聚合物相比无明显变化;在石粉含量为20%(质量分数)时,复合材料的拉伸屈服强度仍然保持了与聚合物几乎相同的数值。研究结果显示,石粉作为一种惰性填料,完全能够用于LDPE的填充改性。

| Abstract: | We tried to apply the by-product during stone processing,i.e.,the abandoned stone powders into polyethylene composites.The crystallization kinetics,morphology and mechanical performance of the low density polyethylene(LDPE)/stone powder composites were investigated by DSC,XRD angle X-ray diffraction and electronic universal testing machine.The results showed that:1) the stone powders have limited influences on the crystallization behavior of LDPE,the crystallization peak temperature and the half width of th... |
