摘要
研究了过氧化物DCP、DCP/S并用硫化体系及共交联剂ZDMA的加入对三元乙丙胶/丁腈胶(EPDM/NBR)共混胶性能的影响。研究表明:在过氧化物硫化体系中,随DCP用量的增加,共混胶综合性能先提高后降低,DCP用量为3份时性能达到最佳;DCP/S并用硫化体系中,随硫磺和促进剂加入量的增加,共混胶硫化速度提高,但综合力学性能降低;共交联剂ZDMA由0份增加至15份,共混胶力学性能显著增加,老化性能没有改善。
This paper studies the peroxide DCP, DCP / S curing system and the performance of EPDM/ NBR blends while adding crosslinking agent ZDMA. The researchs shows that： In the peroxide curing system,with the increase of DCP content, the overall performance of blends is first increased and then decreased, with 3 DCPs to achieve the best performance; in DCP / S curing system, with the increase of sulfur and promote agent, the vulcanization rate is increaed, but the mechanical properties is decreased; ZDMA increases from 0 to 15, the mechanical properties of blends are significantly increased, while the aging performance is not improved.
