Description

  The present invention relates to a coating material, a magnetic substrate coated with the coating material, and a method for forming a magnetized surface formed by coating the coating material, and displays a magnet block, a magnet sheet, a magnet hook, a magnet clip, etc. The present invention relates to a paint, a magnetic substrate, and a method for forming a magnetized surface for providing a magnetizing space in which various magnets represented by magnets for magnets can be magnetized.

  Magnets such as ferrite magnets and neodymium magnets used in various shapes of magnets such as magnet blocks, magnet sheets, magnet hooks, and magnet clips are magnetically attached to the magnetic material. Therefore, in order to magnetize magnets such as magnet sheets and magnet hooks on walls and panels, a metal partition is installed or a board such as a whiteboard is attached, and this is used for posting such as magnetic sheets and magnet hooks. A magnet was magnetized to display the desired item. However, when a metal partition is installed, there is a problem that when a metal partition is installed, a large area is required, the metal partition is heavy, and the installation cost is high. In addition, when a white board is attached, there is a problem that the installation place is limited depending on the material and structure of the wall surface to be attached, and it cannot be attached anywhere.

The following techniques have been devised for mixing metal powder such as iron powder into the paint. The electromagnetic wave shielding paint is an electromagnetic wave shielding paint containing at least a binder liquid that expresses non-wetting property on the surface of iron particles constituting iron powder and iron powder, and has non-wetting property on the surface of iron particles. The binder solution has a large surface tension and is a paint that effectively blocks electromagnetic wave noise by utilizing the phenomenon that non-affinity is expressed with respect to the iron particle surface (Patent Document 1). In addition, the soft pigment and its method of use are those in which iron powder itself is pulverized into flakes and used as a glossy pigment as a metallic effect pigment (Patent Document 2). Further, iron oxide powder for coloring pigments is also a powder as a so-called luster pigment for magnetic toner (Patent Document 3). Furthermore, the primary rust preventive paint composition contains a siloxane-based binder, zinc powder as a pigment, and a ferric oxide source and a molybdenum compound as pigments other than zinc powder. It is a composition, and is a rust preventive agent that is applied to form a base film in the first stage of so-called coating (Patent Document 4). However, none of these have a structure as a paint or magnetic substrate for magnetizing a magnet.

A magnetized space or object that can be easily and inexpensively magnetized at locations where a magnet is not magnetically attached by simply applying it to a space or object that is originally a non-magnetic material, such as a panel. Can be processed. And since this magnetic adhesion space is formed by the paint, the place where the paint was applied can be used as the magnetized surface. What is the wall surface when installing a metal partition or whiteboard? There is no need to prepare an object to be magnetized separately, the area of the wall surface can be used effectively, and the beauty of the wall surface is not impaired. As a result, for example, in a house, office, or store, the wall surface itself can be a magnetized surface, without any special work such as drilling a hole in the wall surface or attaching a reinforcing material. The magnetized surface can be formed without impairing the aesthetic appearance. Therefore, for example, a magnet such as a magnet sheet that represents a picture, a figure, a character, or a magnet hook that hangs clothes, a forehead, or the like can be directly magnetized at a desired position. In an exhibition hall or the like, the panel itself used in a limited exhibition area can be a magnetized surface. Therefore, it is possible to directly magnetize the magnetic sheet or the exhibit displaying the exhibition contents on the panel, and the limited space can be effectively utilized. Further, when the paint is applied to an object such as a toy or a stationery, a magnet can be magnetically attached to the object to which the paint is applied.

  In addition, since the iron powder mixed into the paint is reduced iron powder, the reduced iron powder having a large number of voids in the particles has good affinity with the paint, and when this reduced iron powder is mixed into the paint, The black color of iron powder is hardly developed. In addition, the problem of the flat reduced iron powder is that light is irregularly reflected on the particles and only a part of the color component of the paint is visible, and the color of the paint appears dull. This is particularly noticeable when iron powder is mixed in a colored paint containing a colored pigment, and even if iron powder is mixed, the color of the colored paint hardly changes. Therefore, it is possible to provide a magnetic substrate having a good color and a desired color.

  Further, since the particle size of the iron powder is 10 μm to 60 μm, it has good affinity with the paint, and when this iron powder is mixed into the paint, the black color of the iron powder is hardly colored.

Therefore, it is possible to provide a paint that can surely magnetize the magnet for a long time and has good color development.

  In addition, by mixing 40 parts by weight to 60 parts by weight of iron powder with respect to the paint, it is possible to provide a paint having a strength that can be reliably magnetized without dropping the magnet.

  In addition, since the paint is a colored paint, it is possible to provide a magnetized surface of a desired color that can magnetize the magnet when this paint is applied.

  The magnetic substrate of the present invention can easily magnetize a magnet by coating the surface of the substrate with a paint capable of forming a coating film in which iron powder is mixed with the paint and magnetized. A lightweight and inexpensive magnetic substrate can be provided. Therefore, by simply bonding and installing the magnetic substrate, a place where the magnet is not magnetically attached can be made a magnetic attachment space anywhere.

  In addition, since the iron powder mixed into the paint is reduced iron powder, the reduced iron powder having a large number of voids in the particles has good affinity with the paint, and when this reduced iron powder is mixed into the paint, The black color of iron powder is hardly developed. In addition, the problem of the flat reduced iron powder is that light is irregularly reflected on the particles and only a part of the color component of the paint is visible, and the color of the paint appears dull. This is particularly noticeable when iron powder is mixed in a colored paint containing a colored pigment, and even if iron powder is mixed, the color of the colored paint hardly changes. Therefore, it is possible to provide a magnetic substrate having a good color and a desired color.

This is particularly noticeable when iron powder is mixed in a colored paint containing a colored pigment, and even if iron powder is mixed, the color of the colored paint hardly changes. Therefore, it is possible to provide a magnetic substrate having a good color and a desired color.

  In addition, since the iron powder is subjected to rust prevention processing, there is no problem that the magnet does not magnetically adhere to the iron powder and the iron powder rusts and discolors the paint even after being mixed in the paint. Therefore, it is possible to provide a magnetic substrate that can surely magnetize a magnet for a long time and has good color development.

  In addition, the substrate is wallpaper that is adhered to the wall surface, a panel that forms the posting surface, and a wall surface building material that forms the inner wall surface of the building, so that the magnet can be magnetized simply by adhering this wallpaper to the wall surface. A surface can be provided and a room of the desired color can be provided. In addition, a magnetized space can be easily formed simply by installing this panel. In addition, it is possible to provide a magnetized wall surface on which a magnet can be magnetized simply by interior decoration using the wall surface building material. Therefore, the interior decoration of the desired color which can magnetize a magnet easily directly can be provided.

  Further, the substrate is a pressure-sensitive adhesive sheet obtained by applying a pressure-sensitive adhesive on the back surface of the coating surface of the paint, or a re-peeling sheet formed by applying a pressure-sensitive adhesive that can be peeled off to the back surface of the coating surface of the paint. Thus, the surface to be magnetized can be obtained simply by adhering this sheet to the portion where the magnet is to be magnetized. Further, by using a re-peeling sheet, adhesion and peeling can be repeated, and a magnetized surface can be temporarily formed.

  The method for forming a magnetized surface according to the present invention comprises applying a paint capable of forming a coating film in which iron powder is mixed into a paint to magnetize the magnet, thereby forming the magnetized surface. The magnetized surface can be formed at a desired position simply by coating the film.

  In addition, the first coating layer is formed by applying a coating material capable of forming a coating film in which iron powder is mixed into the coating material and the magnet is magnetized, and a desired color is formed on the surface of the first coating layer. By applying a colored paint containing the above pigment to form the second coating layer, the magnetized surface can be formed and the pigmented color can be developed as it is. Can be provided. In addition, when the paint for forming the second coating layer is also a paint capable of forming a coating film in which iron powder is mixed into the paint and the magnet is magnetized, the magnet is magnetically attached to the surface to be magnetized. Is more certain.

  In addition, a colored paint capable of forming a coating film in which iron powder is mixed into the paint and magnets are magnetized is applied to form a first paint film layer, and a first paint film layer is formed on the surface of the first paint film layer. By applying a paint having the same color as that of the paint film forming the second paint film layer, a vivid color surface layer can be provided. For example, if the first coating layer is formed with a yellow paint mixed with iron powder, and the second coating layer is formed with the same color yellow paint without iron powder mixing, the first coating layer has a yellow base. When formed, the second coating layer develops a bright yellow color and can provide a brightly colored magnetized surface.

  The magnet magnetized on the coating film is a posting magnet such as a magnet block, a magnet sheet, a magnet hook, a magnet clip, etc., so that a desired posting can be made only by magnetizing various magnets.

FIG. 4 is a perspective view of a state in which a wallpaper coated with the paint of the present invention is adhered to a wall surface and a magnet hook is magnetically attached thereto, and FIG. 5 is a view in which a weak adhesive is applied to the back surface. FIG. 6 is a schematic cross-sectional view of a re-peeled sheet in which a paint is applied to the surface of a pressure-sensitive adhesive sheet in which a pressure-sensitive adhesive is applied to the back surface, FIG. 7 is a diagram showing reduced iron powder mixed in the paint of the present invention, and FIG. It shows the particle shape of the reduced iron powder is a particle cross-sectional view of a reduced iron powder shown in Fig.

  The paint 1 of the present invention is a colored paint containing red, blue, yellow, or a colorant obtained by mixing them, and is a paint obtained by mixing iron powder as a magnetic material and kneading it.

  The reduced iron powder mixed in the paint is different from other iron powders having a round shape without voids in particles represented by atomized iron powder, as shown in FIGS. The iron powder has a large number of voids and has a flat particle shape. Therefore, the reduced iron powder has good affinity with the paint, and when this reduced iron powder is mixed with the paint, the paint and the reduced iron powder are in close contact with each other, and because of the flat shape, there is little irregular reflection of light. The black color of the iron powder is hardly visible, and the color component of the pigment can be clearly recognized. Therefore, a paint with good color can be provided. This is particularly noticeable when reduced iron powder is mixed in a colored paint containing a colored pigment. The color of the paint hardly changes, and the most suitable paint is provided by making each color stand out. We were able to.

  Table 1 shows a paint in which reduced iron powder is mixed in a colored oil paint at a ratio of 1: 1, a paint in which atomized iron powder is mixed in a ratio of 1: 1 in a colored paint, and a state in which no iron powder is mixed. When the same amount of colored paint is applied to a wooden board, the colored oil-based paint is mixed with the reduced iron powder in a ratio of 1: 1 to the colored paint in which iron powder is not mixed. The result of having visually recognized the change of the color with the paint which mixed the atomized iron powder in the ratio of 1: 1 is shown. In the red paint and the blue paint, there was almost no change in the color of the paint in which the reduced iron powder was mixed into the colored paint at a ratio of 1: 1. On the other hand, a paint in which atomized iron powder is mixed in a colored paint at a ratio of 1: 1 can be visually recognized that both the red paint and the blue paint are close to gray and the color is dull, and both the brightness and saturation are lowered. did it. As for the yellow paint, the paint in which the reduced iron powder was mixed with the colored paint at a ratio of 1: 1 approached the gray color slightly, and the color was dull. On the other hand, a paint in which atomized iron powder was mixed in a colored paint at a ratio of 1: 1 developed a gray color.

  Moreover, it is suitable and desirable that the particle size of the reduced iron powder mixed in the paint is 10 μm to 60 μm. When the particle size is less than 10 μm, there is a problem that even when the iron powder is too fine and mixed in the paint, light is irregularly reflected on the particles, and only a part of the color component of the paint is visible, and the color of the paint appears dull. In addition, when the particle size exceeds 60 μm, there is a problem that the compatibility of the mixed paint is poor and the blackness of the iron powder particles in the paint can be clearly recognized. Furthermore, more preferably, if the average particle size of the iron powder is 40 μm to 50 μm, it is easy to be mixed in the paint and has good affinity with various paints, and the black color of the iron powder is not colored. The most suitable paint could be provided by highlighting the color of the pigment. This is the same for each sample having an average particle diameter of 44.3 μm, an average particle diameter of 31.9 μm, and an average particle diameter of 23.1 μm among the reduced iron powders having a particle diameter that has been confirmed to highlight the color tone of each pigment. When mixed in the paint, the reduced iron powder having an average particle size of 44.3 μm was confirmed by making the color tone of each pigment stand out most.

  Further, it is desirable that the iron powder is not oxidized on the surface or is subjected to rust prevention processing in advance so that the surface is not oxidized. Thereby, even after mixing in the paint, there is no problem that the magnet is not magnetized by oxidation, the iron powder rusts and the paint is discolored.

  Moreover, it is more desirable to mix iron powder with 40 parts by weight to 60 parts by weight with respect to the paint. When a coating containing less than 40 parts by weight of reduced iron powder is applied and a magnet is magnetized on this surface, a heavy magnet or a magnet with weak magnetizing force may fall. On the other hand, the paint in which the reduced iron powder is mixed in an amount of more than 60 parts by weight with respect to the paint has an excessive amount of the reduced iron powder with respect to the paint, and the paint may approach a gray color. If 40 parts by weight to 60 parts by weight of the reduced iron powder is mixed with the paint, the amount of the reduced iron powder with respect to the paint is not too much, and the magnet is reliably magnetized. The amount of iron powder with respect to the paint varies depending on various factors such as the magnetic force and weight of the magnet to be magnetized and whether or not a non-magnetic material is interposed between the coated surface and the magnet. It is not limited.

  Thus, if the average particle diameter is 10 μm to 60 μm and the powder is a flat iron powder and does not have an oxide film (rust), the light reflection of the powder when mixed with the paint is made. The color of the pigment having a high rate and contained in the paint reaches the eye, making the color tone of each paint stand out, making it an ideal magnetic material capable of magnetizing a magnet using the paint as a medium.

  The coating material 1 thus produced can be easily applied by diluting with a solvent such as water, petroleum, alcohol, acetone, hexane, or medium. Then, the paint 1 is provided as it is or enclosed in a container. By applying the paint 1 to a desired location, the wall such as an inner wall of a house or a store or an outer wall of a building, a sheet body, a panel, etc. It is possible to form magnetized surfaces on which magnets are magnetized on various surfaces such as toys and stationery.

  Next, the second embodiment of the paint is a transparent paint containing no colored pigment. The transparent paint is a paint obtained by mixing iron powder, which is a magnetic material on which a magnet is magnetized, into a transparent paint and kneading it. In other words, the paint 1 is a colored paint containing a colored pigment. However, if the paint does not contain a colored pigment, a paint having magnetism of a transparent color can be provided. In particular, when iron powder is mixed into a paint made of a medium resin, a suitable transparent paint can be made, and when this is applied, a magnetized surface can be formed without changing the color of the wall surface or the like. it can.

  Next, a method for forming the magnetized surface will be described. As described above, as shown in FIG. 1, a magnet is magnetized as shown in FIG. 1 in a paint 1 in which liquid powder is mixed with iron powder having the property that a magnet is magnetized, in particular, reduced iron powder. It is applied to the application surface 2 to be formed with a magnetized surface by various methods such as application by brush, roller, etc., spraying by spraying or the like. As a result, a magnetized surface is formed at a location where the paint 1 is applied to the application surface 2, and the magnet 3 can be magnetically attached to this surface.

  Further, as shown in FIG. 2, the other method of forming the magnetized surface is to apply the paint 1 to the coating surface 2 as the base to be formed on the magnetized surface on which the magnet is magnetized. The coating layer is formed. As a result, a magnetized surface is formed on the coated surface to which the paint 1 has been applied. Then, when the first coating layer is completely or partially dried, a coating 8 having the same color as the color contained in the first coating is applied to the surface 2 of the first coating layer. The coating layer is formed. A magnetized surface in which the color of the paint 8 is vividly colored without dullness is formed, and the magnet 3 can be magnetized on this surface.

  If it is desired to more reliably magnetize the magnet, the paint forming the second coating layer is mixed with iron powder having the property that the magnet is magnetized into the paint for the liquid paint. The paint can be used. Further, the paint forming the first coating layer may be a transparent paint.

  FIG. 3 shows a specific example in which the paint 1 is applied. By spraying and applying the paint 1 to the inner wall 4 of the house with a spray gun 5 or the like, the inner wall 4 can be colored in a desired color, and the inner wall 4 can be easily made a magnetized surface. If the magnet hook 6 is magnetically attached to the inner wall 4 to which the paint 1 is applied, the hook portion 61 can be hooked with anything such as a forehead or clothes.

  An example of the magnetic substrate is shown in FIG. The wallpaper 7 is a sheet body made of paper wood, resin, or the like used as a wall surface material, and the paint 1 is applied to the wallpaper 7 in advance. If this wallpaper 7 is bonded to the inner wall 4 of the house, the wall of the desired color can be formed by bonding the wallpaper of the desired color to the inner wall 4, and the inner wall 4 where the wallpaper 7 is bonded can be easily covered. It can be a magnetized surface. If the magnet hook 6 is magnetically attached to the wallpaper 7, the hook portion 61 can be hung with anything such as a forehead or clothes.

  In addition, as an example of a magnetic substrate (not shown), it is possible to provide a board on which a panel for forming a posting surface is formed by applying the paint 1 in advance. Thereby, the display surface which can magnetize a magnet with a desired color can be provided. By forming an exhibition panel using this panel, it is possible to provide a display surface on which a magnet can be magnetized in a desired color.

  In addition, as another example of the magnetic substrate (not shown), it is also possible to provide a coating material that is previously applied to a wall surface building material that forms a wall surface of a house or a store. Thereby, the wall surface which can magnetize a magnet with a desired color can be provided. By forming the inner wall of the building using this wall surface building material, it is possible to provide a wall on which a magnet can be magnetized in a desired color.

  Another example of the magnetic substrate is a re-peeling sheet 9 shown in FIG. In the re-peeling sheet 9, the paint 1 is applied to the surface 92 of the sheet-like re-peeling sheet main body 91, and the weak adhesive 10 having re-peelability is applied to the back surface 93. Therefore, if the back surface 93 of the re-peeling sheet 9 is adhered to a place where it is desired to be a magnetized surface, the magnet 3 can be magnetically adhered to the surface 92 to which the paint 1 is applied. The present state can be restored by peeling off the release sheet 9. And the re-peeling sheet 9 can repeat adhesion and peeling many times. And since the re-peeling sheet main body 91 is a thin sheet body, it can also be provided in the state wound up in tape shape.

  Another example of the magnetic substrate is an adhesive sheet 11 shown in FIG. In the pressure-sensitive adhesive sheet 11, the paint 1 is applied to the front surface 13 of the sheet-shaped pressure-sensitive adhesive sheet main body 12, and the pressure-sensitive adhesive 15 is applied to the back surface 14. Therefore, if the back surface 14 of the pressure-sensitive adhesive sheet 11 is bonded to a place where it is desired to be magnetized, the magnet 3 can be magnetically bonded to the surface 13 to which the paint 1 is applied, and the pressure-sensitive adhesive sheet 11 is firmly bonded.
