Abstract
Abstract A ferric oxide (Fe2O3)/silicone rubber (SR) composite was prepared to produce a magnetic rubber with good heat-resistant and friction properties: SR and nano-Fe2O3 were used as its raw materials. The heat-resistant, antiflaming, magnetic, and mechanical properties of such composites with different proportions of nano-Fe2O3 were studied. The results showed that the Fe2O3 nanoparticles were uniformly distributed throughout the composites. The physical and mechanical properties of SR were improved when Fe2O3 nanoparticles were added. The maximum elongation and tensile strength of the composites were relatively good when the ratio of Fe2O3 was 20 phr. The heat-resistance and antiflaming properties of SR were improved by adding nano-Fe2O3, which had good combined heat resistance. The friction properties of these composites were optimal at 20 phr addition of nano-Fe2O3, which laid the foundation for further applications of this type of composite in high-temperature sealing and shock absorption environments.
