摘要:
采用Isayev模型和Piloyan模型拟合得到不同三元乙丙橡胶(EPDM)与二元乙丙橡胶(EPR)质量比的EPDM/EPR共混胶硫化动力学参数和反应活化能,考察了EPDM与EPR质量比对共混胶硫化特性、物理机械性能及耐老化性能的影响。结果表明,Isayev模型和Piloyan模型可以较好地描述EPDM/EPR共混胶的硫化反应过程,但Piloyan模型无法描述共混胶的焦烧期反应;随着EPR用量的增加,共混胶硫化反应活化能升高,硫化速率减慢;硫化胶物理机械性能下降,耐老化性能提高。
Abstract:
Isayev model and Piloyan model were used to fit the vulcanization kinetics parameters and reaction activation energy of ethylene-propylene-diene monomer (EPDM) /ethylene-propylene rubber (EPR) blends with different mass ratios of EPDM to EPR. The effects of mass ratio of EPDM to EPR on curing characteristics, physical and mechanical properties, and aging resistance of the blends were investigated. The results showed that Isayev model and Piloyan model could describe vulcanization reaction process of EPDM/EPR blends well, while Piloyan model could not describe scorch period reaction of the blends. With increasing amount of EPR, the activation energy of vulcanization reaction of the blends increased, vulcanization rate decreased, phy-sical and mechanical properties of the vulcanizates decreased, and the aging resistance improved.
