<p><P>PROBLEM TO BE SOLVED: To fix a reinforcing sheet temporarily to a steel sheet by magnetic force alone while release paper made unnecessary in order to facilitate the correction of the sticking position of the reinforcing sheet and to make the reinforcing sheet remain at an exact position by preventing the falling or peeling of the reinforcing sheet after its position is corrected. <P>SOLUTION: Barium ferrite and additives such as sulfur, a curing agent, and a foaming agent are mixed into a rubber type synthetic resin, and the mixture is molded into a sheet 1 of 1.0 mm thickness, and a glass cloth of 0.2 mm in thickness which is treated with a melamine resin is made a constraint layer 2. The magnetic sheet 1 is fixed temporarily to the steel sheet 3 at a prescribed position by magnetic force alone, heated, and fusion-bonded. Since the sheet 1 is fixed temporarily by magnetic force alone, the release paper which has been necessary so far is made unnecessary, contributing to the improvement of workability and the reduction of waste. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
