Description

    The present invention relates to rubber and synthetic resin foam magnets.

  In the conventional magnetic health belts, there are a lot of products that use a sponge and magnet, such as a cloth belt with a pocket and a solid magnet in it, a sleep pillow, an eye mask, etc. There are no magnets.

There are many products that use sponges and magnets in combination, but since the sponge itself has not been developed until now, it has been cumbersome to manufacture, costly, and limited in design.
If a sponge magnet is made, the manufacturing cost will be greatly reduced and the choice of design will be greatly expanded.

  When making rubber magnets, ferrite or rare earth magnets such as samarium cobalt and neodymium are generally kneaded into the rubber and magnetized, but foam itself is difficult because it affects the crosslinking of the rubber. It was. Therefore, in order to solve this problem, as shown in [Best Mode for Carrying Out the Invention], the type and amount of rubber crosslinking agent, anti-aging agent, and vulcanization accelerator are adjusted, and the magnetic material itself such as ferrite is crosslinked. The problem was solved by acting as an accelerator and vulcanization accelerator.

  As the filling amount, for example, 100 PHR to 1000 PHR can be mixed depending on the magnetic force, such as value ferrite and neodymium.

  By using the sponge itself as a magnet, most products that have previously been bonded and sewn together can be commercialized with this sponge magnet alone. In addition, since it is a sponge, it can be quantified and its industrial effects such as reduction of manufacturing costs and widening of the selection range of designs cannot be measured.

  When producing a sponge magnet, neodymium is most suitable in terms of the strength of magnetic force, cost, and specific gravity, and single-sided multipole magnetization is desirable as a magnetization method.

  In addition, since it is a sponge, the fabric can be laminated, so it is suitable for use in close contact with the human body.

  The structure in the case of producing a fishing glove, an eye mask, etc. using the sponge magnet shown in the formulation example will be described with reference to FIG. 1 in FIG. 1 is a magnetized sponge magnet. 4 nylon jerseys are laminated using 3 adhesives to facilitate attachment and detachment to the non-magnetized surface and to allow sewing. A magnetized surface of a sponge magnet is used on the side that requires magnetism. For example, when used for the palm of the fishing glove of FIG. 2, a nylon laminated surface is used on the inner side, and a fishhook is pulled using magnetizing a sponge magnet on the outer side.

It is a block diagram of the cross section when using a sponge magnet for goods. It is a block diagram of the fishing glove using a sponge magnet.
