| 摘 要： | 研究了2,5-二甲基-2,5-二（叔丁基过氧基）己烷（俗称双二五）、2,4-二氯过氧化苯甲酰（俗称双二四）、过氧化二异丙苯（DCP）3种硫化剂对陶瓷化耐火硅橡胶力学性能和烧结性能的影响。结果表明,一次硫化和二次硫化后,使用DCP做硫化剂的硅橡胶的硬度都是最大,使用双二五做硫化剂的硅橡胶的拉断伸长率都是最高,采用双二四做硫化剂的硅橡胶拉伸强度都是最大;使用双二四做硫化剂的硅橡胶烧结硬度最高。综合来看,使用双二四作硫化剂时陶瓷化耐火硅橡胶的力学性能最好,其最佳用量为1.25份。

| Abstract: | The effect of 3 vulcanization reagents on the mechanical properties and sintering performance of a fire resistant ceramic silicone rubber was studied. They were 2,5-dimethyl 2,5-di（tert-butylperoxy）hexane（DBPH）,2,4-dichloro-benzoyl peroxide（DCBP）and dicumyl peroxide （DCP）. Results show that after one-step curing and post curing,the hardness of the fire resistant ceramic silicone rubber is the maximum with DCP as the curing agent. The tensile elongation of the fire resistant ceramic silicone rubber is the highest with DBPH as the curing agent. The tensile strength of the silicone rubber is the maximum with DCBP as the curing agent. The sintering hardness of the rubber is the highest with DCBP as the curing agent. Taken all together, the mechanical properties of the fire resistant ceramic silicone rubber is the best with DCBP as the curing agent with 1. 25 parts. |
