Zusammenfassung: | PROBLEM TO BE SOLVED: To develop a sheet for reinforcing a steel sheet for a car which does not need the sticking of release paper, can be fixed by magnetic force, and has performance at least equivalent to a conventional reinforcing sheet. SOLUTION: In the magnetically attached steel sheet reinforcing sheet, a rubbery synthetic resin such as polybutadiene rubber or 1,2-polybutadiene rubber is used as a binder, and magnetic powder is incorporated in the resin. Magnetic force is applied to the sheet to make the sheet be stuck on the surface of an oily surface steel sheet by magnetic force alone. The sticking position of the sheet is kept even in a car washing process, a chemical treatment process, and an electrodeposition coating process. The sheet is fusion-bonded to the steel sheet by heating after the electrodeposition coating. COPYRIGHT: (C)2007,JPO&INPIT |
