| 中文摘要: |
| 对EPDM的过氧化物硫化、硫黄硫化和含硫化合物硫化以及两种不同硫化体系并用的硫化胶热稳定性进行比较，优选热稳定性较好的硫化体系用于产品的制造。采用过氧化二异丙苯(DCP)硫化的硫化胶虽具有极好的热稳定性，但其耐撕裂性能较差，且价格较高，因此可考虑采用DCP的并用硫化体系。当DCP用量为5份，硫黄用量不超过1份时，硫化胶具有较好的热稳定性。 |
| 英文摘要: |
| A optimized thermal-stable curing system has been found ro be used in production through the comparison among the thermal stabilities of EPDM vulcanizates cured with peroxide，sulfur，sulfur-containing compound and two different blend curing systems respectively.The vulcanizate cured with DCP features the excellent thermal stability，but lower tear strength and higher price.Thercfor the blend curing systems of DCP are adopted.The EPDM vulcanizate will show better thermal stabiliry when 5 phr of DCP and less than 1 phr of sulfur are used in The blend curing system. |
