摘　　要：以丁腈橡胶和氯丁橡胶为基质,通过添加磁性材料十二羰基三铁制备了能够减小汽油表面张力、提高其燃烧效率,从而降低有害气体排放的磁性橡胶复合材料,研究了复合材料的力学性能、耐油和耐老化性能、磁性能以及对汽油理化性能的影响及其机理。结果表明,磁性橡胶复合材料具有良好的力学性能及耐油和耐老化性能,当磁性材料添加量为1份(质量)时其综合性能最佳。复合材料作用于汽油后,通过增强汽油中有机分子的振动和转动来改善其雾化和气化质量,进而提高燃烧效率。A type of magnetic rubber composite that could decrease the surface tension of gasoline , enhance combustion efficiency and reduce the emission of exhaust gas was prepared with nitrile rubber and chloroprene rubber as matrix , triiron dodecacarbonyl as magnetic filler.The mechanical properties , oil resistance and aging resistance of the functional composite were studied , the magnetic property of the composite and its effect on the physical and chemical properties of gasoline and the effect mechanism were investigated.The results showed that the composite＆amp;nbsp;had good mechanical properties , oil resistance and aging resistance , and its all-round properties was the best at 1 phr magnetic filler.The composite could increase the combustion efficiency of gasoline by enhancing the vibration and rotation of gasoline molecules to improve the atomization and gasification levels.
