摘　　要：以氢氧化甲基丙烯酸锌(HZMMA)和炭黑N774为混合补强剂,制备出HZMMA/N774增强的氢化丁腈橡胶(HNBR)复合材料。采用差示扫描量热(DSC)、傅里叶变换红外光谱(FT-IR)、X射线衍射(XRD)研究了复合材料硫化过程中的形态结构演变及力学性能的变化。结果表明,在硫化剂过氧化二异丙苯(DCP)作用下,HZMMA的不饱和双键的伸缩振动吸收峰和晶体的特征衍射峰迅速消失。随着硫化时间的延长,橡胶复合材料的拉伸强度和100%定伸强度小幅增大,撕裂强度和扯断伸长率逐渐减小。经过二段硫化,其100%定伸强度戏剧性增加,拉伸强度和硬度进一步增加,断裂伸长率和撕裂强度下降。Hydroxyl zinc mono-methacrylate composites were prepared using HZMMA and （ HZMMA）/carbon black/hydrogenated nitrile rubber （ HNBR ） carbon black N774 as mixed reinforcing agent. The morphology structure evolution and mechanical properties of the composites were studied by DSC, FT-IR, XRD during the vulcanization process. The results show that the stretching vibration absorption peak of unsaturated double bond and the characteristic diffraction peak of the crystal rapidly disappear using dicumyl peroxide as curing agent. With the prolongation of the curing time, the tensile strength and modulus at 100 % of the composites increase slightly, and the tear strength and elongation at break decrease. After the post curing, the modulus at 100 % increases, the tensile strength and hardness increase further, and the elongation at break and tear strength decrease
