| 中文摘要: |
| 采用过氧化物交联方法研究了交联聚乙烯的工艺条件和性能，探讨了交联反应对交联聚乙烯力学性能和交联度的影响，并用差示扫描量热仪表征了交联聚乙烯的熔融行为。结果表明：交联剂双2,5用量（质量分数）为1.5％，交联温度为180 ℃，交联时间为5 min时，交联聚乙烯的交联度达到74.2％，拉伸强度为29.0 MPa，断裂伸长率为480％，其熔融峰温度为108.7 ℃。 |
| 英文摘要: |
| Process conditions and properties of crosslinking polyethylene were studied by peroxide crosslinking method. Effect of the crosslinking reaction on mechanical properties and crosslinking degree of the crosslinking polyethylene was discussed. Melting behavior of the crosslinking polyethylene was characterized by DSC. The result showed that when crosslinking agent double 2,5 is 1.5%, reaction temperature is 180 ℃, reaction time is 5 minutes, the crosslinking degree of the crosslinking polyethylene reaches 74.2%; the tensile strength is 29.0 MPa and elongation at break is 480％; its melting temperature is 108.69 ℃. |
