采用溶液共混母胶法制备了纳米石墨/氢化丁腈橡胶（HNBR）复合材料，研究了其微观结构、硫化性能、力学性能、耐磨性能等，并将其与采用传统机械共混法制备得到的复合材料进行对比。结果表明：溶液共混母胶法可使纳米石墨更加均匀地分散在HNBR基体中；与传统机械共混法相比，用溶液共混母胶法制备的复合材料的硫化性能和力学性能更优，最大综合扭矩、弹性模量、交联程度、硫化速率分别提高了35%，44%，32%，46%，但该工艺对复合材料拉伸强度和耐磨性能的提高作用不明显。

The nanographite composite/hydrogenated nitrile rubber (HNBR) was prepared by the solution blending masterbatch method, and the microstructure, vulcanization properties, mechanical properties, wear resistance were studied and compared with those of the composite prepared by the traditional mechanical blending method. The results show that the solution blending masterbatch method could make the nano graphite more uniformly disperse in the HNBR matrix. Compared with the composite by the traditional mechanical blending method, the composite prepared by the solution blending masterbatch method had better vulcanization and mechanical properties; the maximum comprehensive torque, elastic modulus, crosslinking degree, vulcanization speed increased by 35%, 44%, 32%, 46%, respectively, but the effect of the process on the improvement of tensile strength and wear resistance of the composites was not obvious.
