| 中文摘要: |
| 研究了相容剂及其用量和加工工艺对EPDM/三元共聚尼龙(PA)共混体系物理性能的影响。结果表明，氯化聚乙烯(CPE)是EPDM/PA共混体系性能优良且价廉易得的相容剂;CPE的最佳用量为PA的1/2。
SEM照片显示，EPDM与PA相容性差;二元体系EPDM/PA加入CPE后，分散相PA/CPE分散均匀，粒径细小。共混温度控制在(160±5)℃为宜，PA与CPE共混时间控制在15 min为宜，EPDM与CPE/PA的混炼时
间控制在8 min为宜。还考察了加料顺序对共混物性能的影响。 |
| 英文摘要: |
| The influence of the kind and level of compatibilizer and the blending technology on the physical properties of EPDM/PA blend was investigated.The results showed that CPE was a suitable and cheap compatibilizer for EPDM/PA blend; and its optimal content is 50% by weight of PA.It was found on SEM that the compatibility between EPDM and PA was poor; and the uniform dispersion and small particles were obtained in the dispersive PA/CPE phase by adding CPE into EPDM/PA blend. It was suitable to blend at (160±5)℃, 15 min for PA/CPE and 8 min for EPDM with PA/CPE respectively.The influence of the loading order on the properties of blend was also studied. |
