摘　　要：进行两种无铅无促进剂ETU硫化体系[三嗪硫化体系(硫化剂TCY/促进剂DPG/碳酸钙/氧化镁硫化体系)和喹喔啉硫化体系(硫化剂XL-21S/促进剂P-152/氢氧化钙/氧化镁硫化体系)]与有害的亚乙基硫脲硫化体系(促进剂ETU/四氧化三铅和促进剂ETU/氧化镁硫化体系)对二元共聚氯醚橡胶(ECO)性能影响的对比试验。结果表明:喹喔啉硫化体系胶料硫化速度快、交联程度高、物理性能良好,但抗焦烧性能差,喹喔啉硫化体系可作为ECO的无铅无促进剂ETU的环保硫化体系替代传统促进剂ETU/四氧化三铅硫化体系;三嗪硫化体系胶料硫化速度适中、抗焦烧性能和交联效果较好,硫化特性和物理性能与传统促进剂ETU/氧化镁硫化体系胶料相近,但必须解决非环保促进剂DPG的替代问题。The comparative tests of lead-free and accelerator ETU-free environmentally-friendly curing systems[triazine curing system（vulcanizater TCY/accelerator DPG/Ca CO3/Mg O system） and quinooxaline curing system（vulcanizater XL-21S/accelerator P-152/Ca（OH）2/Mg O system）] and harmful ethylene thiourea curing system（accelerator ETU/Pb3O4 and accelerator ETU/Mg O）on effect of properties of epichlorohydrin copolymer（ECO）were made. Results showed that the compound containing quinooxaline curing system gave faster curing rate,higher degree of crosslinking,better physical properties,but poor scorch resistance,it could be used as a lead-free and accelerator ETU-free environmentally-friendly curing systems alternative to the traditional accelerator ETU/Pb3O4 curing system for ECO. The compound containing triazine curing system gave moderate curing rate,better scorch resistance and crosslinking effect,curing characteristics and physical properties similared to compound containing conventional accelerator ETU/Mg O curing system,but the problem of non-environmentally-friendly accelerator DPG alternating must solved.
