Abstract
This work presents the preparation of rubber compounds containing new ferrite pigment for making new elastomeric magnetic composites with good properties and high savings. The pigment incorporated in this work is a new ferrite/kaolin core-shell pigment which contains a thin shell of ferrites not exceeding 10-15% of the whole pigments deposited on kaolin surface representing the core and comprises 85-90% of the pigment. These pigments have concomitant savings and are advantageous of combining the properties of both its components and overcoming their deficiencies. The evaluation of these new magnetic fillers influence on curing characteristics, physical-mechanical and magnetic properties will be estimated; these rubber ferrite composites have the advantage of easy mouldability and flexibility. Also, the effect of loading on the cure characteristics, physical-mechanical and magnetic properties of these rubber ferrite/kaolin composites will be evaluated. The study showed that, the tensile strength and elongation at break of the composites increased up to 50 parts per hundred rubber (phr) of ferrite and then decreased at higher loading whereas the hardness was increased gradually with increasing of ferrite/kaolin loadings. The magnetic tests showed that the saturation magnetization (M s ) and not the coercivity (H C ) is the dominant factor which affects the energy loss in the rubber composites. © 2013 Elsevier Ltd.
