The MH/Fe3O4/SR magnetic rubber composites were prepared with SR, nano-Fe3O4 and nano-MH as raw materials. The friction, heat-resistant, physical and mechanical properties of the MH/Fe3O4/SR composites were studied using different proportions of nano-Fe3O4 and nano-MH. The results show that nano particles are well distributed in the silicone rubber matrix. The physical and mechanical properties of silicone rubber are effectively improved by different ratios of Fe3O4/MH. When the ratio is 20phrMH/10phrFe3O4, the tensile strength and elongation of the composites are somewhat improved, increase by 5%, compared with common silicone rubber.With the increase of the addition of nano MH and Fe3O4, the heat-resistant and friction properties of composites are continuously improved, the friction coefficient is effectively demoted. When the ratio is 30phrMH/10phrFe3O4, the decomposition temperature of the composites increases to 450℃. When the ratio is 20phrMH/20phrFe3O4, the friction coefficient of the composites is demoted to 0.52.
