摘要
以 N,N’-间苯撑马来酰亚胺(PDM)为氯磺化聚乙烯橡胶(CSM)的硫化剂或硫化助剂,考察了 CSM 混炼胶的硫化性能、硫化胶的物理机械性能和热空气老化性能。结果表明,在 MgO/PER/TRA硫化体系中,PDM是有效的防焦剂,采用PDM/防老剂 AW硫化体系可以制得压缩永久变形和耐热性能优良的硫化胶。
The vulcanization properties of chlorosulfonated polyethylene rubber ( CSM ) compounds, the mechanicl and heat againg properties of the vulcanizates prepared with N,N'-meta-phenylene-bis-maleimide ( PDM ) as vulcanizator or secondary vulcanizator were investigated. The results showed that PDM was an effective scorch retarder for MgO/PER/TRA vulcanizing systems, and the vulcanizates with excellent compression permanent set and heat resistance could be obtained by PDM/antioxidant AW vulcanizing systems.
