20090110587 | Method for manufacturing laminated soft-magnetic sheet - A method for producing a laminated soft-magnetic sheet is provided by laminating thin soft-magnetic sheets produced by an application method. A change in sheet thickness can be suppressed and variations in the magnetic permeability are small. The method for manufacturing a laminated soft-magnetic sheet includes the step (A) of obtaining curable soft-magnetic sheets, each of the curable soft-magnetic sheets being produced by applying to a release base a soft-magnetic composition prepared by mixing at least a flat soft-magnetic powder, an acrylic rubber having a glycidyl group, an epoxy resin, a latent curing agent for the epoxy resin, and a solvent, drying the applied soft-magnetic composition at a temperature T | 04-30-2009 |

20100001226 | Sheet-like soft magnetic material and production method thereof - The present invention is to impart, to a sheet-like soft magnetic material, a configuration in which sheet thickness change is suppressed and in which fluctuation in magnetic permeability is small even under a high-temperature or a high-temperature, high-humidity environment, even when a plurality of thin curable soft magnetic sheets produced by a coating method are laminated. The sheet-like soft magnetic material is formed from a soft magnetic composition which is formed by mixing at least a flat soft magnetic powder, an acrylic rubber, an epoxy resin, a curing agent for the epoxy resin, and a solvent. The flat soft magnetic powder is arranged in an in-plane direction of the sheet-like soft magnetic material. An acrylic rubber having a glycidyl group is used for the acrylic rubber. The weight ratio of the flat soft magnetic powder with respect to the total amount of the acrylic rubber, the epoxy resin, and the curing agent for the epoxy resin is 3.7 to 5.8. | 01-07-2010 |
20100012881 | METHOD FOR MANUFACTURING MAGNETIC SHEET AND MAGNETIC SHEET - In manufacturing a magnetic sheet, the magnetic sheet is formed by applying on a prescribed substrate a magnetic paint made from a mixture of at least flat soft magnetic powder and polymeric binder dissolved in a solvent and drying the magnetic paint. Subsequently, the magnetic paint is further coated on the magnetic sheet formed by drying the magnetic paint and is dried. Thus, an extremely high quality magnetic sheet is made with high productivity. | 01-21-2010 |
