TECHNICAL FIELD OF THE INVENTION
The present invention uses a sheet-like magnet as a ferromagnetic adherend, for example, an iron plate, a blackboard, a bulletin board, a partition using an iron powder-kneaded rubber sheet, and a detachable display member by a magnetic attraction force. The present invention relates to a display mechanism and a wall surface mounting mechanism in which a surface material of a building wall can be freely attached and detached (replaced).
[0002]
[Prior art]
Conventionally, a sheet-like magnet having a thickness of about 0.6 mm and a multi-pole magnetization of 2.5 mm to 5 mm pitch in a stripe shape from one side is used as a display member on an adherend made of an iron plate, for example, a blackboard, a partition, or the like. I was In addition, characters and pictures as display pieces are provided by screen printing or laminated on a plastic film or the like.
[0003]
When this display member is adhered to an adherend, the magnetic poles are also strong on the back surface, so when a sheet-like magnet is adhered on top of it as a display piece, it is similarly magnetized between the same poles. Otherwise, the phenomenon of lifting due to the same polarity repulsion and not being able to adhere to the entire surface, or the drawback that if the pole directions of both poles are not the same, even if they are between the same poles, overlapping portions of the same polarity will occur and the magnetic attraction force will decrease There is.
As a countermeasure against the inconvenience due to the same polarity repulsion, a means has been proposed in which the first display piece is a sheet-like magnet, the second display piece is a sheet-like ferromagnetic material, and the third display piece is a sheet-like magnet. Have been. (See Patent Document 1)

[0005]
[Problems to be solved by the invention]
In the means disclosed in Patent Document 1, since a sheet piece magnet and a sheet-like ferromagnetic material need to have a thickness of about 0.5 mm to 0.8 mm in order to obtain a practically necessary attractive force of the display piece. In order to provide characters and pictures as display pieces, it is necessary to perform screen printing or to laminate those printed on a plastic film or the like because the thickness is large, but in many cases, the first display piece is large. Since it is used in an area, it is desirable that the surface has a printable layer that can be printed by a printing machine such as a copying machine or a printer, and that the printable thickness is about 0.4 mm or less in total thickness. is necessary.
Further, if the cap magnet is magnetically attracted through the primary display piece made of a sheet-like magnet, there is a disadvantage that a weak magnetic attraction force occurs because the sheet-like magnet having a lower permeability and a larger thickness than the iron plate is interposed.
In addition, the secondary display piece, it is desirable that the display piece made of a sheet magnet used for the conventional display plate can also be diverted, and even if the secondary display piece is a sheet-like magnet, A display mechanism that does not cause a decrease in magnetic attraction force has been strongly desired.

[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
(With display mechanism)
As the ferromagnetic layer of the adherend A of the present invention, a ferromagnetic sheet made of an iron plate or ferromagnetic fine powder (for example, soft magnetic material fine powder such as iron powder or soft ferrite powder) and an organic polymer elastomer is used. In addition, blackboards, whiteboards, partitions, etc. made of iron plates can be used. Alternatively, a surface layer may be provided by laminating or painting a film on the surface of an iron plate or a ferromagnetic sheet.
[0016]
As the base material of the thin-layer magnet of the present invention, paper, synthetic paper, plastic film, metal foil, cloth and the like can be used. It is good to be able to print with.
The magnet layer of the thin-layer magnet of the present invention is obtained by kneading a magnet material fine powder into an organic polymer elastomer and forming it into a sheet by a known method, and laminating the base material to the base material, A method of forming a magnet layer by coating a coating liquid comprising a magnet material fine powder, an organic polymer elastomer and a solvent by a known method is preferred.
[0017]
Examples of the magnetic material fine powder used for the thin layer magnet of the present invention include hard magnetic material fine powders such as ferrite, manganese / aluminum, samarium / cobalt, neodymium / iron / boron, and samarium / iron / nitrogen. Can be Among them, ferrite, which is an oxide-based magnetic material, is practically most preferable because it is free from oxidation deterioration in air, has a large coercive force, and is inexpensive.
[0018]
The production of an ultra-thin material with the thin-layer magnet of the present invention is performed by using a paper or synthetic paper as a base material, and using a coating liquid comprising a magnetic field-oriented anisotropic ferrite fine powder, an organic polymer elastomer, and a solvent. The coating and the magnetic field orientation treatment are preferably performed using a coater line for producing a magnetic tape.
[0019]
In terms of the thickness of each layer of the thin-layer magnet of the present invention, the substrate preferably has a thickness in the range of about 0.035 mm to 0.15 mm, and if less than about 0.035 mm, the hiding power of the lower magnet layer with respect to the color tone. And the mechanical strength is insufficient. If the thickness exceeds about 0.15 mm, the concealing power and the mechanical strength are excessive, which is uneconomical. In addition, the air gap becomes large with respect to the magnet attached to the surface of the thin layer magnet, which is not preferable. The magnet layer is preferably in the range of 0.035 to 0.25 mm, and if it is less than about 0.035 mm, the magnetic attraction may be insufficient. On the other hand, when the thickness exceeds about 0.25 mm, the thickness of the thin layer magnet is increased, and the necessity of increasing the thickness and magnetic force of the magnet to be adhered to the surface arises. The total thickness is preferably 0.4 mm or less, and if it exceeds 0.4 mm, the air gap of the magnet, which is a secondary display piece adhered to the surface in some cases, reduces the magnetic attraction force, and may cause It is not preferable because magnetic repulsion cannot be ignored. In addition, printing may not be performed by a printing machine such as a copying machine or a printer.
[0020]
Magnetization of the thin-layer magnet of the present invention is performed by a known method, that is, a one-turn magnetized yoke is brought into close contact with the magnet layer surface of the unmagnetized raw material of the thin-layer magnet, and magnetized by applying a DC pulse current. Can be done. In this case, the distance between the poles of the multipolar magnetization is preferably in the range of 1 mm to 2 mm. If the thickness is less than about 1 mm, it is difficult to manufacture a magnetized yoke, and heat generation due to continuous magnetization is large, which is not practical. . If the thickness exceeds about 2.0 mm, the thickness becomes excessively large with respect to the thickness of the thin-layer magnet, and the expression efficiency of the magnetic attraction force is deteriorated.
[0021]
Another known method is a composite permanent magnet magnetizer in which a plurality of flat plate-shaped permanent magnets magnetized in a direction perpendicular to the flat plate surface are arranged in a row with the same polar faces facing each other. Can be used for magnetization. In this case, the gap between the multipolar magnetizations is preferably in the range of about 0.3 mm to about 2 mm. If the gap is less than about 0.3 mm, it is difficult to manufacture a sintered magnet used in a composite permanent magnet magnetizer, which is not preferable. .
[0022]
As the sheet magnet C1 magnetically adhered to the surface of the thin-layer magnet of the present invention, a commercially available magnet sheet, that is, a magnet sheet composed of a ferrite-based magnet material fine powder and an organic polymer elastomer, or a rare earth magnet material fine powder and an organic polymer A magnet sheet made of an elastomer can be used. The thickness is preferably in the range of about 0.3 mm to about 6 mm. If the thickness is less than about 0.3 mm, when the magnetic layer is magnetically adhered to the surface of the thin layer magnet, the influence of the thin layer magnet may not be neglected in some cases. In some cases, if the thickness exceeds about 6 mm, the magnetic attraction force may be more than necessary in some cases, which is uneconomical, and the workability of surface mounting, cutting, and cutting as a display member is undesirably reduced.
The gap between the multi-pole magnetized poles is preferably in the range of about 1 mm to about 8 mm, more preferably about 2 mm to about 5 mm, and if less than about 1 mm, the air gap due to the thin-layer magnet cannot be neglected. If the thickness exceeds, the gap between the thickness and the thickness becomes excessive, and the efficiency of expressing the magnetic attraction force deteriorates. Also, commercially available thick magnets, i.e., cylindrical and prismatic magnets, can be used, and multipole magnetized magnets and magnets with thickness direction magnetized yokes can also be used. Also, a commercially available strip-shaped magnet with one-sided two-pole magnetization can be used.
[0023]
By increasing the magnetic attraction force in use between the multi-pole magnetized poles of the sheet magnet C1 and the thin layer magnet B, and increasing the magnetic attraction force during use, the sheet magnet C1 can be positioned at any position and in any direction of the thin layer magnet B. Can be magnetically attracted (attached), preferably, as described above, the total thickness of the thin-layer magnet B 'is about 0.4 mm or less, the gap between multi-pole magnetized electrodes is about 2 mm or less, and the sheet-like magnet C1' In addition to making the gap between the multipolar magnetizations of about 2 mm or more, the magnetic attraction force (when superimposed and adhered to the thin-layer magnet) when using the sheet-like magnet C1 'is different from that of the thin-layer magnet B'. That is to make it about twice or more. If it is less than about two times, it may not be possible to attach it to an arbitrary position and an arbitrary direction in some cases, which is not preferable.
[0024]
The surface of the thin-layer magnet and the sheet-like magnet of the present invention can be used by appropriately painting, displaying and printing as a display piece. Further, in the case of a sheet-like magnet, a coloring film, display printing or the like can be used by laminating a surface film. Also, the display paper can be held between the thin-layer magnet and the above-described cylinder, prism, or strip magnet.
[0025]
(About wall mounting mechanism)
As the adherend A of the present invention, a wall is used as a substrate, and a ferromagnetic material composed of an iron plate or a ferromagnetic fine powder (for example, a soft magnetic material fine powder such as an iron powder and a soft ferrite powder) and an organic polymer elastomer is provided on the surface thereof. The body sheet is attached via an adhesive.
As the thin magnet-made wall surface material B 'of the present invention, a flexible thin magnet B' similar to the display mechanism described above can be used.
As the flexible sheet magnet C1 'of the present invention, the same sheet magnet C1' as the display mechanism can be used.
[0026]
Further, after magnetically attaching the thin magnet-made wall surface material B ′ to the adherend A, as a cutout material (blindfold material), the base (adherend A) surface is not exposed due to dimensional shrinkage over time. Further, a tape-shaped sheet magnet C1 ′ may be magnetically attached to the four peripheral edges to eliminate the possibility that the edges are peeled off from the edges due to curl floating and strong wind over time, or to drop off due to vibration. preferable. In this case, the sheet-like magnet C1 'can be formed into a shape that also serves as a decoration.

[0059]
[Table 3]

[0060]
* 1 to * 4 in Table 3 will be supplemented.
* 1: In Examples 1 to 6, since the magnetic attraction force of the first display piece, which is a thin-layer magnet, is weak, the correction of sticking can be slightly shifted while being attracted, and air pockets can be generated. Comparative example 1 is a flexible sheet-like magnet, whereas it can be easily removed, so it has a strong attraction force and cannot be slightly displaced while being attracted, making it difficult to remove air pockets. Poor sex.
[0061]
* 2: In Examples 1 to 6, both the first display piece and the second display piece can be attached without gaps, and can be attached at any position and in any direction. In Example 1, since the magnetized poles of the first display piece and the second display piece are different from each other, a portion of the same polarity repulsion is generated and floated, so that the entire surface cannot be adhered, and the magnetic attraction force is significantly reduced. .
[0062]
* 3: In Examples 1 to 5, the upper and lower ends of the first display piece are lifted by about 0.05 mm, and the upper and lower ends are shrunk by about 1 mm, but to the extent that there is no practical problem. On the other hand, in Example 5, since neither lifting nor shrinkage of the end portion is recognized, even if strong wind hits from the side, it exhibits excellent adhesiveness without fear of peeling.
* 4: Shrinkage of 4 mm is noticeable at the upper and lower ends of the first display piece.
[0063]
【The invention's effect】
1. When magnetically adhering the secondary display piece or the pattern, etc., on the primary display piece or the wall surface covering material, it can be magnetically adsorbed in any position and in any direction without causing magnetic repulsion between them. In addition, the magnetic attraction force of the cap magnet is less likely to decrease.
2. Since the primary display piece, which is often used in a large area, is a thin layer, it can be printed, and since the magnetic attraction force is small, the position and direction at the time of operation can be easily corrected. Great improvement effect.
[0064]
3. Especially for wall coverings, it is possible to apply a stripping material and anti-peeling tape (similar to a secondary display piece) to the four peripheral edges at any position and in any direction. Excellent.
4. In particular, in the case of the wall surface replacement work, the construction time can be shortened. Therefore, in the case of a 24-hour non-holiday business store that has recently increased, the economic effect of shortening the closing time is large.
