摘　　要：采用炭黑、白炭黑、甲基丙烯酸锌(ZDMA)并用增强氢化丁腈橡胶(HNBR)/乙烯丙烯酸酯橡胶(AEM)共混胶,考察了白炭黑和ZDMA并用比例对共混胶硫化特性、物理机械性能、耐热老化性能及动态力学性能的影响。结果表明,当炭黑用量为固定值、白炭黑和ZDMA总量不变时,随着ZDMA用量的增加,HNBR/AEM共混胶的硫化速率加快,加工性能改善,拉伸强度和邵尔A硬度变化不大,撕裂强度、扯断伸长率、100%定伸应力和压缩永久变形增大;ZDMA的加入可改善HNBR/AEM共混胶的耐热老化性能和低温性能。Effect of blending ratio （mass ratio） of silica and zinc dimethacrylate （ZDMA） on the curing characteristics,mechanical properties,heat aging resistance and dynamic mechanical property of hydrogenated nitrile rubber （HNBR）/ethylene-acrylate rubber （AEM）blends reinforced by carbon black/silica/ZDMA were investigated.The results showed that under the condition of invariant amount of carbon black and total amount of silica and ZDMA,with the increase of ZDMA amount,the curing rate of HNBR/AEM blends accelerated,processing performance improved,tensile strength and Shore A hardness changed little,and tear strength,elongation at break,modulus at 100％ and compression set increased.The addition of ZDMA improved heat aging resistance and low temperature performance of HNBR/AEM blends.
