| 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。

| Abstract: | A optimized thermal-stable curing system has been found to be used in productionthrough 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 DC.P features the excellent thermal stability, but lower tear strength andhigher price. Therefor the blend curing systems of DCP are adopted. The EPDM vulcanizate willshow better thermal stability when 5 phr of DCP and less than 1 phr of sulfur are used in theblend curing system. |
