Title: Composite resin magnet roll composition
Inventor: KARIYA KOTARO
IPC: H01F7/02
Filed: 1985-02-06
Abstract: PURPOSE:To obtain a composite resin magnet roll having high productivity which assures high magnetic force and orientation integration with a shaft by simultaneously using polyamide resin having a melting viscosity of a particular value or less and wax, aliphatic metal salt. CONSTITUTION:A composite resin magnet roll composition 2 using polyamide resin having melting viscosity of 50 poise or less at 200 deg.C has a very low viscos ity at a plastic condition and easily allows the axis for easy magnetization 4 of ferrite to be oriented very easily in the direction in line of magnetic flux against the oriented magnetic field. Therefore, a resin magnet roll 3 having a high magnetic force can be obtained. In this case, a magnet roll having melt ing viscosity of 50 poise or more has a larger resistance of viscosity and also has bad magnetic characteristic because orientation is interferred. Desirable amount of ferrite contained is 80-92wt% for total weight. If it exceeds 92wt%, kneading and molding become difficult and moreover deterioration of magnetic characteristic can also be detected. If it is under 80wt%, orientation of ferrite becomes higher for the oriented magnetic characteristic but magnetic characteris tic is lowered because amount is insufficient.
