| 摘 要： | 将自制的甲基丙烯酸锌［（Ｚｎ（ＭＡＡ）２］与丁腈橡胶（ＮＢＲ）共混，采用就地反应法制得了高性能的ＮＢＲ／Ｚｎ（ＭＡＡ）２合金。结果表明，高Ｚｎ（ＭＡＡ）２用量的合金体系在较低过氧化二异丙苯用量下即可取得良好的综合力学性能；合金具有较好的耐热氧老化性能和热稳定性；动态粘度谱仪分析表明，合金体系中ＮＢＲ相的Ｔｇ向高温方向移动，说明Ｚｎ（ＭＡＡ）２与ＮＢＲ有较强的化学和物理作用。

| Abstract: | High performance NBR/zinc methacrylate(Zn(MAA)2)]alloy was produced by blending NBR with Zn(MAA)2 by using in- situ reaction.The results showed that the alloy with high amount of Zn(MAA)2 had good comprehensive mechanical properties at lower DCP concentration.The alloy vulcanizate had good aging resistance property and heat stability.DMA analysis showed that Tg of NBR phase moved to higher temperature.It indicated that crosslinking reaction occurred between Zn(MAA)2 and NBR during the curing process. |
