Abstract
In this study, we used nano-SrO.6Fe 2 O 3 particles as modified filler to prepare nitrile butadiene rubber/SrO.6Fe 2 O 3 composites. Surface microstructure of the composites was observed using scanning electron microscope, the distribution of nano-SrO.6Fe 2 O 3 particles was measured by energy-dispersive X-ray spectrometer, and magnetic properties of the composites were tested by a U5-10 magnetizer. The results showed that nano-SrO.6Fe 2 O 3 particles were closely inosculated with nitrile butadiene rubber and well distributed in the nitrile butadiene rubber matrix. With adding different mass fractions of nano-SrO.6Fe 2 O 3 , stress at 300% definite elongation, maximum elongation, and tensile strength of the composites were slightly decreased, but shore A hardness of the composites was markedly improved. Magnetic properties of the composites were uncorrelated to the degree of scatter of nano-SrO.6Fe 2 O 3 particles, and relied only on mass fraction of nano-SrO.6Fe 2 O 3 particles. The nitrile butadiene rubber/SrO.6Fe 2 O 3 composites have good soft magnetism performance, which laid the foundation for further application of the composites.
