Abstract
A magnetic adhesive tape and a method for manufacturing the magnetic adhesive tape. A high-effect releasing agent and a property-changing agent are added into a soft magnetic material and blended with each other to form a strip-like soft magnetic substrate with releasable surface. One face of the substrate is purified or roughened and coated with a high-effect adhesive layer. The substrate is wound on a reel. An outer end of the wound substrate can be drawn out segment by segment for use.
Claims24
A magnetic adhesive tape comprising an elongated magnetic tape to which a high-effect releasing agent is added, whereby the entire surface of the tape has high releasing capability, one face of the tape being surface-treated and then coated with an adhesive layer.
A method for manufacturing magnetic adhesive tape, comprising steps of:
- mixing a magnetizable material, a rubber/plastic complex material, a high-effect releasing agent and a property-changing agent with each other and evenly blending the mixture;
- making a thin tape from the mixture;
- surface-treating at least one face of the tape;
- magnetizing the tape;
- and
- coating the treated face with an adhesive.
