Description

  The present invention relates to a magnet-attachable glass film.

  Flat glass is often used for windows on the outer walls of buildings such as offices, stores, and residences. Also, plate glass is often used for walls inside buildings, fixtures for displaying products, and display fixtures for displaying exhibits.

  Various items such as memos, writing instruments and bulletins are placed in offices, stores and residences. These supplies are stored in storage shelves and attached to bulletin boards, and are attached to steel furniture and refrigerator doors with magnets. However, steel furniture and refrigerators are only located in offices, stores, and residences. For example, steel furniture is used in offices but rarely used in homes. In addition, the refrigerator is installed only in the kitchen in the house, and is only disposed in the corner of the room in the office.

  Therefore, the present invention provides a magnet-attachable glass film that makes effective use of plate glass frequently used in buildings and makes it possible to easily attach various articles such as memos, writing utensils, and postings to plate glass with magnets. Let it be an issue.

  The present invention provides a strong re-adhesive layer on the other side of the base film with a releasable adsorption layer that can be attached to the plate glass so that the magnet can be attached to the plate glass frequently used in buildings. A coating film containing magnetic fine particles was provided.

  Specifically, the present invention includes a resin base film, a releasable adsorption layer formed on one surface of the base film, which can be attached to a plate glass, and the other base film. And a coating film containing ferromagnetic fine particles applied to the surface.

  If it is the said magnet-attachable glass film, since the adsorption layer is formed in one surface of a base film, it can stick to plate glass. And since the coating film containing the ferromagnetic fine particles is formed on the other surface of the base film, the ferromagnetic fine particles contained in the coating film when the magnet is brought into contact with or close to the coating film Receives an external magnetic field from a magnet and is magnetically polarized. As a result, a magnetic force acts between the ferromagnetic fine particles contained in the coating film and the magnet that contacts or approaches the coating film, and the magnet is attracted to the coating film.

  If the magnet attachable glass film is used, various articles can be attached to a window glass or the like with a magnet. Therefore, conventionally, offices, stores, and dwellings where the number of places that can be pasted with a magnet are almost limited can be effectively utilized. That is, in the past, articles could be pasted with magnets, for example, only in very limited places such as refrigerators and steel furniture, but by using the magnet-attachable glass film, It is possible to effectively use plate glass such as window glass provided in the living room, increasing the degree of freedom of attaching articles using magnets.

The coating film may contain fine iron particles. If iron fine particles are contained in the coating film, a magnetic force acts between the magnets in contact with or approaching the coating film and the fine particles contained in the coating film, and the magnet can be attracted to the coating film.

  Further, the base film and the adsorption layer may be colorless and transparent. If the base film and the adsorption layer are transparent, the color of the coating film can be seen through the plate glass. Therefore, when various designs are drawn with the paint film, the design drawn with the paint film can be shown through the plate glass.

  According to the present invention, it is possible to effectively use plate glass frequently used in buildings and easily attach various articles such as memos, writing instruments, and postings to the plate glass with magnets.

FIG. 1 is a perspective view showing an example of a magnet-attachable glass film according to the embodiment. FIG. 2 is a diagram illustrating an example of a cross-sectional structure of the magnet-attachable glass film according to the embodiment. FIG. 3 is a diagram showing an example of how to use the magnet-attachable glass film.

  Hereinafter, embodiments of the present invention will be described. The following embodiments are exemplifications, and the technical scope of the present invention is not limited thereto.

  FIG. 1 is a perspective view showing an example of a magnet-attachable glass film according to the embodiment. The magnet-attachable glass film 1 according to this embodiment is a film having an appropriate size that can be easily attached to a plate glass. In addition, although the rectangular magnet-attachable glass film 1 is illustrated in FIG. 1, the magnet-attachable glass film 1 is not limited to such a shape. The magnet-attachable glass film 1 may exhibit, for example, a square, a circle, an ellipse, a rhombus, a triangle, a pentagon, and other various shapes.

  FIG. 2 is a diagram illustrating an example of a cross-sectional structure of the magnet-attachable glass film 1 according to the embodiment. As shown in FIG. 2, a magnet-attachable glass film 1 according to this embodiment is attached to a plate glass formed on one surface of a resin-made base film 2 and a base film 2 as a base. A possible releasable adsorption layer 3 and a coating film 4 containing ferromagnetic fine particles applied to the other surface of the base film 2 are provided. The surface of the adsorption layer 3 is covered with a release film 5 that prevents adhesion of foreign matter. The release film 5 is peeled off from the adsorption layer 3 when the magnet-attachable glass film 1 is attached to a plate glass.

  The base film 2 is a film that plays a role as a base material for forming the adsorption layer 3 and the coating film 4. The material constituting the substrate film 2 may be any material as long as it can serve as a substrate for forming the adsorption layer 3 and the coating film 4. Examples of the material constituting the base film 2 include polyester. Polyester is excellent in strength, workability, and heat resistance, and is also excellent in dimensional stability because it does not easily expand and contract, so that it can withstand application to a window glass or the like exposed to sunlight. In addition, as a raw material which comprises the base film 2, acrylics, a polycarbonate, a polyimide etc. are mentioned other than polyester, for example.

The base film 2 may have any thickness, but considering the ease of pasting work, productivity, durability, etc., in the case of polyester, it is about several tens μm to several hundreds μm. Preferably, the thickness is If the thickness of the base film 2 is too thin, it will be difficult to ensure the strength required as a film to be attached to the plate glass 6. Moreover, when the thickness of the base material film 2 is too thick, there exists a possibility that sticking may become difficult by productivity fall or productivity may fall remarkably.

  The base film 2 and the adsorption layer 3 may be colorless and transparent, or may be colored. If the base film 2 and the adsorption layer 3 are colorless and transparent, the color of the coating film 4 can be seen through the plate glass. Therefore, when various designs are drawn with the coating film 4, the design drawn with the coating film 4 can be shown through plate glass.

  The adsorption layer 3 is a layer formed by applying an adsorbing material to the base film 2 and plays a role of fixing the magnet-attachable glass film 1 to a plate glass as an adherend. The adsorbing layer 3 may be formed of any material as long as it has an adsorptive property that can be re-peeled to the plate glass. If the adsorptive layer 3 is formed of an adsorptive material that can be re-peeled from the plate glass, for example, when attaching various articles to the plate glass with a magnet, the magnet attachable glass film 1 is attached to the plate glass, The magnet-attachable glass film 1 can be easily peeled from the plate glass when it is no longer necessary to attach the article. Therefore, even a general user who does not have a special technique can easily attach and detach the magnet-attachable glass film 1.

  The coating film 4 is a coating film formed by applying a coating material containing ferromagnetic fine particles to the base film 2. The ferromagnetic fine particles contained in the coating film 4 are magnetically polarized by receiving an external magnetic field from the magnet when the magnet contacts or approaches the coating film 4. As a result, a magnetic force acts between the ferromagnetic fine particles contained in the coating film 4 and the magnet that contacts or approaches the coating film 4, and the magnet is attracted to the coating film 4. The ferromagnetic fine particles contained in the coating film 4 may be anything as long as the magnet is attracted by a magnetic force. For example, fine particles made of a so-called iron group element such as iron or nickel can be applied. It is. It is preferable that the coating film 4 has a strength that can withstand an impact or the like upon contact with various articles. Examples of the coating material that forms the coating film 4 include MagPaint (registered trademark) manufactured by MagPaint Europe, which contains iron fine particles in an aqueous acrylic latex coating material. The thickness of the coating film 4 is not particularly limited, but when using MagPaint, if the coating film 4 is formed to have a thickness of, for example, about 250 μm, various articles such as paper and writing instruments can be magnetized using a magnet. The magnetic force which can be affixed to 1 can be produced.

  The release film 5 is a film that can be easily peeled off from the adsorption layer 3. The release film 5 may be formed of any material as long as it can be easily released from the adsorption layer 3. The release film 5 can be formed of, for example, polypropylene.

  FIG. 3 is a view showing an example of how to use the magnet-attachable glass film 1. When the magnet attachable glass film 1 is used, the magnet attachable glass film 1 having the release film 5 peeled off from the adsorption layer 3 is applied to the window glass 6 of the building so that the adsorption layer 3 is in contact with the glass surface. Paste (FIG. 3A). And the magnet 8 is further piled up in the state which applied desired articles, such as the paper 7 which wrote the memo, to the coating film 4 of the magnet-attachable glass film 1, for example. Then, the magnet 8 is attracted to the ferromagnetic fine particles contained in the coating film 4, and the magnet 8 is in a state in which the paper 7 is attached to the magnet-attachable glass film 1 (FIG. 3B). When the paper 7 is to be taken, the magnet 8 can be easily separated from the magnet-attachable glass film 1 by pulling the magnet 8 by hand while grasping the paper 7 by hand, and the paper 7 can be taken.

If the magnet-attachable glass film 1 according to the above-described embodiment is used, various articles such as memos, writing utensils, bulletins, etc. used in offices, stores, residences, etc. are effectively used by making effective use of plate glass such as window glass frequently used in buildings. Can be attached to a window glass or the like with a magnet 8. Therefore, conventionally, offices, stores, and dwellings where the number of places that can be pasted with a magnet are almost limited can be effectively utilized. That is, in the past, it was only possible to attach the article with a magnet, for example, a very limited portion such as a refrigerator or steel furniture, but the magnet-attachable glass film 1 according to the above embodiment was used. By using it, plate glass such as window glass provided in most living rooms can be effectively used, and the degree of freedom of attaching articles using magnets increases.
