Abstract:
      Microwave desulfurization activation of rubber powder was carried out by blending of rubber powder nano-ferrite with strong microwave absorption ability，and the properties of rubber powder/ferrite blends and modified rubber powder/styrene-butadiene rubber（SBR）blends were studied.The results showed that ferrite enhanced the microwave desulfurization activation effect of rubber powder.With the prolongation of microwave irradiation time，the desulfurization activation effect of rubber powder increased until carbonization.When microwave power was 400 W and microwave irradiation time was about 3 min，the desulfurization effect of rubber powder was better，the tensile strength and elongation at break of rubber powder/ferrite vulcanizate were higher.The compatibility of microwave irradiated rubber powder with SBR was improved.With the increase of SBR content，the elongation at break of rubber powder/SBR blend increased，and the tensile strength increased at first，then decreasesd slightly and kept stable quickly.Ferrite played a certain reinforcing role in rubber powder/SBR blend.
