Abstract

PURPOSE:To obtain magnet composition wherein magnetic powder is tightly filled and whose shock resistance and performance are excellent by adding a specified amount of pretreated magnetic powder and either of polyacrylate resin or polyamide resin. CONSTITUTION:Powdered polyphenylene sulfide resin has a benzene ring which is a crystalline aromatic polymer and whose para is replaced and the symmetric main chain comprising a repetitive unit of sulfur atoms. The magnetic powder is prepared by pretreating the powder of a magnetic material which can be powdered to the shape of, for example, about several mu with the desirable 0.005-3wt% of a titanate surface treating agent. To the 100pts.wt of said powdered polyphenylene sulfide resin, are added the desirable weight parts of either of polyacrylate resin or polyamide resin and the desirable 83-90wt% of the magnetic powder. In this method, is obtained the composite material having excellent forming feature, shock resistance, heat resistance, chemical resistance, fire resistance, and high magnetism.
