Problems solved by technology

[0002] The current flexible magnetic strip is mainly bonded by magnetic powder. The surface of the bonded magnetic strip is relatively rough and exposed to the outside world. Therefore, the magnetic powder on the magnetic strip is easy to fall off after repeated friction, and the surface is easy to oxidize. Corrosion, poor waterproof performance, so that after a period of use, the magnetism of the magnetic strip will be seriously affected, and the service life will be short

Abstract

The invention discloses a flexible magnetic strip and a manufacturing method thereof. The flexible magnetic strip comprises a flexible magnetic strip body, wherein a flexible protective sleeve is wrapped on the exterior of the flexible magnetic strip body. The manufacturing method comprises the following steps: first manufacturing the flexible magnetic strip body; then sleeving the flexible protective sleeve on the flexible magnetic strip body; heating; and finally cooling. By adopting the flexible magnetic strip manufactured by the manufacturing method disclosed by the invention, the magnetic powder on the flexible magnetic strip is difficult to drop, the surface of the flexible magnetic strip is not easily oxidized and subject to corrosion, the flexible magnetic strip has good waterproof performance, beautiful appearance and long service life.

Description

technical field [0001] The invention relates to a flexible magnetic strip and a manufacturing method of the flexible magnetic strip. Background technique [0002] The current flexible magnetic strip is mainly bonded by magnetic powder. The surface of the bonded magnetic strip is relatively rough and exposed to the outside world. Therefore, the magnetic powder on the magnetic strip is easy to fall off after repeated friction, and the surface is easy to oxidize. Corrosion, poor waterproof performance, so that after a period of use, the magnetism of the magnetic strip will be seriously affected, and the service life will be short. Contents of the invention [0003] The purpose of the present invention is to provide a flexible magnetic strip. With the structure of the present invention, the magnetic powder on the flexible magnetic strip is not easy to fall off, the surface is not easy to be oxidized, and is not easy to be corroded. It has good waterproof performance, beautiful...
