摘要：

In this paper the mechanical, magnetical and rheological properties are analyzed. The influence of different magnetic powders onto a plasticized polvinyl chloride) were studied. The magnetic characterization of isotropic plastic bonded magnets, based on strontium ferrite (SrFe12O19) and plasticized polyvinyl chloride, as a function of composition was analyzed in a magnetometer at room temperature. in order to explain the dependence of the volumetric density and the saturation magnetization with composition, an additive model for these properties is considered. The intrinsic coercivity shows a decrease with increasing strontium ferrite content, which is due to the increasing interaction between the magnetic particles. The maximum energy product is lower than 1 MGOe and increases with the second power of the strontium ferrite content. The rheological properties were studied in a capillary rheometer; it was found that viscosity increased as the magnetic powder concentration increased in the composite.
