硫化橡胶体系的物理性能受硫化工艺和所形成交联键化学性质的影响。多硫键的动态性质提高了系统的使用性能,但也促进了硫化返原。硫化返原是由于网络降解而导致物理性能下降的现象。硫化返原由热引发,主要与过硫和高温使用条件有关。硫化返原过程中发生多硫交联键脱硫的反应以
The physical properties of the vulcanized rubber system are influenced by the vulcanization process and the chemical nature of the crosslinked bonds formed. The dynamic nature of the polysulfide bond improves system performance but also promotes sulfidation. Vulcanization is due to degradation of the network caused by physical degradation of the phenomenon. Vulcanization back to the original by the heat-induced, mainly with the use of sulfur and high temperature conditions. Sulfidation back to the process of polysulfide cross-linking desulfurization reaction
