Abstract
A composite magnetic body is obtained without the use of halogen-based or halogen-containing materials, such as, halogen-based binding agent of halogen-based resins or elastomers, and bromine-based fire retardents. The composite magnetic body (1) comprises a soft magnetic powder (2) and a silicone rubber (3). The silicone rubber (3) should preferably be a solid silicone rubber. An electromagnet interference suppressing body is obtained using this composite magnetic body.
Claims14
A composite magnetic body comprising a silicone rubber and a soft magnetic powder dispersed in the silicone rubber, the soft magnetic powder having a specific surface area of 0.1-3 m2/g, wherein the soft magnetic powder is a magnetic alloy powder having a flat shape.
An electromagnetic interference suppressing body for suppressing electromagnetic interference brought about by the interference of unwanted electromagnetic waves, wherein said electromagnetic interference suppressing body is made of a composite magnetic body comprising a silicone rubber and a soft magnetic powder dispersed in the silicone rubber, the soft magnetic powder having a specific surface area of 0.1-3 m2/g, wherein the soft magnetic powder is a magnetic alloy powder having a flat shape.
