Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention L± relates to a sheet material used for painting masks, wall cloths, and various other uses.

BACKGROUND ART Conventionally, masking painting has been applied when painting local parts of steel frames or vehicles, for example, and the mask is a sheet material such as paper or resin film coated with an adhesive on the back side. This sheet material is used to cut into a desired shape and apply a coating to areas that do not require painting, but since it is firmly attached with adhesive, it is not only time-consuming to peel it off after use, but also the adhesive It has the disadvantage that it may remain on the surface of the processed material, requiring removal treatment after the fact, and that it easily loses its tackiness, so it must be discarded every time it is used.

DISCLOSURE OF THE INVENTION The present invention can be used, for example, as a painting mask.
It is an object of the present invention to provide a sheet material that is extremely easy to attach and detach and can be used permanently.

That is, the sheet material according to the present invention includes a magnetic layer formed of magnetic powder, a rubber magnet, etc., and a synthetic resin paper laminated on at least one side of the magnetic layer.

It is formed as a sheet-like magnetized body with a surface layer made of cloth, leather, or other material appropriate for the purpose.

Example The following will be described with reference to the drawings.

In the illustrated embodiment, it is formed as a sheet material laminated in three layers. The intermediate layer 1 is a magnetic layer formed using magnetic powder, rubber magnet, etc., and the surface layer 2. Back layer 3
is made of synthetic resin, paper, cloth, leather, or other materials selected depending on the intended use. The magnetic layer 1 can be formed into a sheet shape in advance, and a resin film, paper, cloth, leather, etc. is laminated thereon to form the surface layer 2. The back layer 3 can be laminated. The magnetic layer 1 can also be formed by coating the sheet material that will become the surface layer 2 to the back layer 3 with magnetic powder mixed with a binder. When the back layer 3 is also made of synthetic resin, it can be formed by coating a sheet of magnetic material.

Note that depending on the application, it is not necessary to provide the back layer 3, and the surface layer side may be formed of a non-magnetically permeable material. The sheet form can be a continuous sheet that can be rolled up, a sized sheet, or a sheet shaped into an appropriate shape, and the surface layer 20 can be formed to have a smooth surface or a rough uneven surface. I can do something.

The sheet-like magnetized body configured in this way can be used as a painting mask,
It can be used for a wide range of purposes, such as wall cloths, price tags attached to vehicles, teaching materials that can be attached to blackboards, etc.

For example, when used as a painting mask, the sheet material S can be cut in advance to match the shape of the workpiece A, such as joints of steel frames or parts of the body of a vehicle that do not require painting. The sheet material S can be easily adsorbed or peeled off by the magnetic action of the magnetic layer 1, and if the surface layer 2 is made of a smooth synthetic resin, the paint can be easily wiped off, making it permanent. It also allows for various uses. In addition, when used as a price tag, the surface is preferably formed of paper on which characters can be written or a resin film with a rough, uneven surface. Can be posted. When used as a teaching material, for example, a plurality of sheet pieces S1, S2...
It can be used for geometric learning such as making triangles, squares, etc. on the panel surface of a blackboard C, and in this case, since each piece is sheet-shaped, it can be handled extremely easily. In addition, when used as a wall cloth, the cloth can be pasted by simply adhering it to the metal base of the base, making it easy to paste and reposition, and it can also be used for applications such as magnetizing posters and pastings onto the wall. also possible.

Effects of the Invention As described above, the sheet-like magnetized material according to the present invention can be easily attached or peeled off for appropriate purposes, and can be permanently attached because the attachment is made possible by the magnetic force line action of the magnetic layer. It can also be used for various purposes.
