摘　　要：探究单甲基丙烯酸锌(HZMMA)在氢化丁腈橡胶(HNBR)形成过程中的作用,并研究HZMMA和炭黑(CB)含量对其性能的影响,通过傅里叶变换红外光谱(FTIR)、透射电子显微镜(TEM)来观察HZMMA原位聚合反应。结果表明,由于均聚反应或HZMMA固体单体接枝聚合反应的发生,离子聚合物渗透到氢化丁腈橡胶中。利用红外光谱和透射电镜证实,聚HZMMA粒子是在氢化丁腈橡胶硫化过程中形成的这种形态的粒子在增强HNBR复合材料性能中起着非常重要的作用。室温下,只添加了PHZMMA的氢化丁腈橡胶复合材料的力学性能比添加了PHZMMA/CB混合物的氢化丁腈橡胶复合材料的性能优越的多;然而,当温度上升到50℃以上,后者的拉伸强度下降缓慢,其抗拉强度总是高于同温下只添加PHZMMA的氢化丁腈橡胶复合材料。在突破80℃是仍表象出这种性质。并且添加了PHZMMA/CB的氢化丁腈橡胶复合材料具有极强的抗老化性能。The morphology evolution of hydroxyl zinc monomethacrylate （HZMMA） in hydrogenated nitrile rubber （HNBR） during its formation, and effect of synergistic behavior of HZMMA and carbon black （CB） in HNBR on its properties, was investigated. Fourier transform infrared spectroscopy （F-FIR）, transmission electron microscopy （TEM） were used to probe the reaction of in-situ polymerized HZMMA. The results showed that an ionic polymer interpenetrating HNBR, due to homo-polymerization or graft polymerization of HZMMA solid monomer occurred, and poly-HZMMA particles, confirmed by FTIR and TEM, were formed during the HNBR vul- canization process. This kind of morphology for the HNBR composites played a very significant role in the HNBR reinforcement. At ambient temperature, the mechanical properties of HNBR composite filled with pure PHZMMA was much superior to those of the HNBR/PHZMMA/CB composites; however, when the temperature was increased to above 50℃, the decrease of the tensile strength for the latter was slower, and the tensile strength was always higher than that of the HNBR composites ieinforced with pure PHZMMA at the same temperature. The elongation at break above 80℃ was also always higher than that of the HNBR/PHZMMA sample. The HNBR/PHZMMMCB composites showed excellent air oven aging resistance.
