摘要
研究过氧化物品种、硫化剂DCP和助交联剂TAIC用量以及硫化剂种类对氟橡胶性能的影响。结果表明:在过氧化物BIPB,DBPMH,DCP,DCBP和BPO中,DCP硫化的氟橡胶综合物理性能较好,压缩永久变形较小;随着硫化剂DCP用量的增大,氟橡胶的压缩永久变形呈减小趋势,硫化剂DCP用量为3份时,氟橡胶的物理性能较好,压缩永久变形较小;随着助交联剂TAIC用量的增大,氟橡胶的压缩永久变形呈减小趋势,助交联剂TAIC用量为5份时,氟橡胶的压缩永久变形较小;硫化剂DCP硫化的氟橡胶耐压缩永久变形性能优于3#硫化剂,但不如双酚AF/BPP。
The effect of peroxide type,addition level of curing agent DCP and secondary curing agent TAIC,and different curing agents on the properties of FKM was investigated.The results showed that,the comprehensive physical properties of FKM cured by DCP were better than those cured by peroxide BIPB,DBPMH,DCBP and BPO,and the compression set was lower.As the addition level of DCP increased,the compression set of FKM decreased.With 3 phr of DCP,the physical properties of FKM with low compression set were better.When the addition level of TAIC increased,the compression set of FKM decreased,and the optimized level was 5 phr.The resistance to compression set of FKM cured by DCP was better than that cured by 3# curing agent,but worse than that cured by bisphenol AF/BPP.
