In addition, "~" represents "greater than or equal to" to "less than or equal to" unless otherwise specified.

(First Embodiment)
1 and 2 are diagrams for explaining the construction method according to the first embodiment. FIG. 1 shows a cross section of a wall constructed by the method of this embodiment. FIG. 2 is a perspective view of the wall constructed by the method of the present embodiment, and a part of the base 20 and the decorative material 10 is omitted. The construction method according to the present embodiment is an interior or exterior construction method in which a decorative material 10 provided with a magnet material 14 is attached to a base 20 containing a ferromagnet.

According to the construction method of the present embodiment, a wall structure including a laminate of a base 20 containing a ferromagnetic material and a decorative material 10 including a magnet material 14 can be obtained. This will be described in detail below.

The construction method of the present embodiment is, for example, a method of constructing an inner wall or an outer wall of a room, a passage, or the like. The building to which the interior or exterior is constructed is not particularly limited, and examples thereof include buildings and houses.

The decorative material 10 is a member that is integrated with the wall to give an aesthetic appearance to the wall. 1 and 2 show an example in which the magnet material 14 is a sheet-shaped magnet layer. Hereinafter, the magnet material 14 will be described as the magnet layer 14, but the magnet material 14 is not limited to the sheet shape. It may be lumpy. The decorative material 10 includes, for example, a decorative layer 12, a magnet layer 14, and an adhesive layer 13 that joins the decorative layer 12 and the magnet layer 14. The decorative material 10 may be in the form of a sheet or a plate. Further, the decorative material 10 may be in the form of a woven fabric. The structure of the decorative material 10 will be described in detail later.

The decorative material 10 is fixed so as to cover almost the entire base 20. For example, 95% or more of the surface of the base 20 opposite to the skeleton 30 is covered with the decorative material 10. In the examples of FIGS. 1 and 2, the base 20 has a plurality of base layers. The base layer is a layer located between the frame of the wall and the decorative material 10. Alternatively, the base layer is a layer in which the frame of the wall is fitted so as to be located inside the wall with respect to the decorative material 10. The base layer exerts functions such as structural reinforcement, heat insulation, moisture proofing, waterproofing, and fire resistance, alone or in cooperation with each other. In the examples of FIGS. 1 and 2, the base 20 includes a first base layer 22 and a second base layer 24. However, the base 20 may further include another base layer. The base 20 is fixed to the skeleton 30.

The skeleton 30 is, for example, the skeleton of a building and is a frame that supports the structure of the building. The skeleton 30 is wood, metal, reinforced concrete, or the like. The base 20 does not necessarily have to be fixed to the building frame 30. For example, the laminate of the base 20 and the decorative material 10 may be a part of the partition that divides the indoor space. Further, the decorative material 10 may function as a corner material with a protruding corner, a parting material, a joiner, a bulletin board panel, or the like.

The base 20 contains a ferromagnet, and a magnet is attracted to the base 20. The ferromagnet is, for example, iron. In the present embodiment, the base 20 includes a ferromagnetic layer containing a ferromagnetic material. For example, at least one of the second base layer 24 and the first base layer 22 is a ferromagnetic layer. Here, it is preferable that the base layer of the base 20 closest to the decorative material 10 is a ferromagnetic layer. By doing so, the fixing strength of the decorative material 10 with respect to the base 20 can be improved. Examples of the base layer other than the ferromagnetic layer include inorganic boards such as calcium silicate board, gypsum board, and volcanic vitreous multi-layer board, and wooden plywood.

In the present embodiment, the ferromagnetic layer is a plate material containing a ferromagnetic material. The plate material containing the ferromagnetic material is a ferromagnetic plate such as an iron plate. Further, the plate material containing the ferromagnetic material may be a composite member of a material other than the ferromagnetic material and a ferromagnetic material such as iron powder or iron foil. By using the composite member, the degree of freedom in shape can be improved and the weight can be reduced. Examples of materials other than ferromagnets include resins, wood, gypsum, calcium silicate, cement, and vitreous materials. In the composite member, the material other than the ferromagnetic material and the ferromagnetic material may be mixed or laminated. The composite member can be obtained, for example, by mixing resin particles, wood chips, or the like with iron powder and forming the composite member into a plate shape. Alternatively, the composite member can be obtained by laminating and adhering a plate-shaped member made of a material other than a ferromagnet and an iron foil. Further, when the base layer is formed of a soil wall, a composite member may be formed by forming the layer using soil mixed with a ferromagnetic material. The thickness of the ferromagnetic layer is not particularly limited, but is, for example, 1 mm or more and 20 mm or less.

The base 20 may contain a ferromagnet in at least a part of the region when viewed from a direction perpendicular to the main surface, and does not need to contain the ferromagnet as a whole. The area of the region containing the ferromagnet with respect to the area of the entire base 20 is not particularly limited, but is preferably 20% or more, and more preferably 50% or more. For example, the substrate 20 may include a ferromagnetic layer patterned in a grid pattern. Further, it is preferable that the region of the base 20 facing the outer periphery of each decorative material 10 contains a ferromagnetic material.

Since the base 20 contains a ferromagnetic material, the magnet layer 14 is attracted to the base 20, and the decorative material 10 can be fixed to the base 20. According to the construction method of the present embodiment, since the decorative material 10 is removable from the base 20, the base 20 is used when the decorative material 10 becomes dirty or damaged, or when the interior or exterior design is to be changed. The decorative material 10 can be easily replaced in a short time without damaging the decorative material 10. In addition, it is not necessary to use an adhesive when fixing the decorative material to the base at the construction site. Therefore, no odor due to an organic solvent or the like is generated during drying. Further, since the base 20 can be quickly and easily fixed to the decorative material 10, the construction period can be shortened.

As shown in FIG. 2, the first base layer 22 and the second base layer 24 may each be formed of a plurality of plate materials. Here, it is preferable that the boundaries of the plurality of plate materials in the first base layer 22 and the boundaries of the plurality of plate materials in the second base layer 24 do not overlap each other except at the intersection. By doing so, it is possible to prevent the fire from leaking from the boundary in the event of a fire, and the fire resistance is improved.

Further, in the second base layer 24 which is the base layer on the most decorative material 10 side, the boundary between the plurality of plate materials is filled with the putty 201. Further, the step generated at the boundary between the plate materials is approximately flattened by the putty 201.

The decorative material 10 is magnetically fixed to the base 20. A plurality of decorative materials 10 may be spread on one wall surface. Then, the decorative material 10 can be easily transported to the construction site. When a plurality of decorative materials 10 are arranged and fixed on the wall surface, a gap may be provided between the decorative materials 10 and the decorative materials 10. Then, even when the decorative material 10 expands or contracts due to moisture or the like, the decorative material 10 is less likely to bend or the like. However, when the entire decorative material 10 is made of a material such as a resin that does not easily expand or contract, it is not necessary to provide a gap between the decorative material 10 and the decorative material 10.

The plate material containing the ferromagnetic material may have one or more openings. Since the plate material has an opening, the weight of the base 20 can be reduced and the seismic resistance of the building can be improved. However, from the viewpoint of improving fire resistance, it is preferable that the opening does not overlap with the boundary between the plate materials constituting the other base layer.

FIG. 3 is a cross-sectional view illustrating the configuration of the decorative material 10 according to the first embodiment. The decorative material 10 according to the present embodiment will be described below. However, the decorative material 10 is not limited to the following structure.

The decorative material 10 includes a decorative layer 12, an adhesive layer 13, and a magnet layer 14. The structure of the decorative layer 12 is not particularly limited, but in the present embodiment, the decorative material 10 includes a surface layer 120 and a core material layer 129. The decorative layer 12 is composed of, for example, a melamine resin, a solid content of a thermoplastic emulsion resin, polyvinyl chloride, polyvinyl fluoride, vinylidene fluoride, polyester, polytetrafluoroethylene, polyolefin resin, and (meth) krill resin. Consists of one or more resins selected from the group.

In the example of this figure, the surface layer 120 is in contact with the core material layer 129. Further, the surface layer 120 includes a printing base material 122, a printing unit 121, a first resin layer 123, and a second resin layer 124. The surface layer 120 is exposed on the first surface 101 of the decorative material 10. However, the surface layer 120 does not have to include the printing base material 122 and the printing unit 121. For example, the surface layer 120 may be designed by including a resin layer or a metal layer that has been embossed to have irregularities. Further, the surface of the first surface 101 of the decorative material 10 may be designed.

The decorative material 10 preferably has flexibility as a whole. Then, it can be fixed to a curved base. Specifically, it is preferable that the decorative material 10 has flexibility to the extent that cracks do not occur when it is curved at 25 ° C. with a bending radius of 10 mm.

The decorative layer 12 is a portion that imparts design to the wall surface. The decorative layer 12 has a design property that causes an aesthetic appearance when viewed from the first surface 101 side. In the example of this figure, the decorative layer 12 is configured so that the design of the printed portion 121, that is, the printed pattern or the like can be visually recognized from the first surface 101 side.

The surface layer 120 supports, for example, a resin containing a melamine resin (first resin layer 123) on the first surface 101 side, which is a design surface, and a thermoplastic emulsion resin on the second surface 102 side in contact with the core material layer 129. It is composed of a surface layer material composed of a printing base material 122 that supports a solid content (second resin layer 124). This will be described in detail below.

The printing substrate 122 is, for example, pulp, linter, synthetic fiber, or glass fiber. Further, the printing base material 122 may be a titanium oxide-containing decorative paper containing a pigment such as titanium oxide.

In the example of this figure, the printing unit 121 imparts design to the decorative material 10. The printing unit 121 is ink supported on the printing base material 122 by printing. The printing portion 121 may be formed in layers on the surface of the printing base material 122, or at least a part thereof may be impregnated with the printing base material 122. The printing method is not particularly limited, but gravure printing, inkjet printing, offset printing and the like can be used.

The first resin layer 123 is a layer containing the resin (A) and is a transparent layer located on the first surface 101 side of the printing substrate 122. The resin (A) contains a melamine-based resin. The resin (A) preferably contains a melamine resin. As a result, the surface of the decorative material 10 contains the melamine resin, and the surface of the decorative layer 12 can be imparted with suitable hardness. As a result, the durability of the decorative material 10 can be increased. In the example of this figure, the first resin layer 123 is exposed on the first surface 101 of the decorative material 10.

The melamine resin is not particularly limited, and for example, a melamine resin obtained by reacting melamine and formaldehyde under neutral or weak alkali can be used.

Further, as the melamine resin, a commercially available melamine resin such as a melamine resin manufactured by Sumitomo Chemical Co., Ltd. can also be used.

The method of supporting the resin (A) on the first surface 101 side of the printing substrate 122 is not particularly limited, and for example, a resin varnish in which the resin (A) is dissolved in a solvent is used, for example, a spray device, a shower device, or the like. Examples thereof include a method of applying by using a device such as a kiss coater or a comma coater, and then heating and drying at about 80 to 130 ° C.

The solvent that dissolves the resin (A) is not particularly limited, and examples thereof include water and methanol. Of these, water is preferable. Further, a poor solvent may be used as long as it does not adversely affect the substance. The solid content of the resin varnish (all components excluding the solvent) is not particularly limited, but is preferably 30 to 70% by mass, more preferably 45 to 60% by mass of the resin varnish. Thereby, the impregnation property of the resin varnish into the base material can be improved.

The second resin layer 124 is a layer containing the resin (B). The resin (B) is, for example, the solid content of a thermoplastic emulsion resin. In the present specification, the thermoplastic emulsion resin is a resin in which the thermoplastic resin is dispersed in a solvent to form an emulsion. Further, the solid content of the thermoplastic emulsion resin means a component obtained by removing the solvent from the thermoplastic emulsion resin.

The solid content of the thermoplastic emulsion resin contains a component existing as emulsion resin particles, has adhesive properties with metals and various materials, and imparts flexibility to the decorative layer 12. Therefore, by supporting the solid content of the thermoplastic emulsion resin on the second surface 102 side of the surface layer 120, the adhesive strength between the surface layer 120 and the core material layer 129 can be improved, and the decorative layer 12 can be improved. Bending workability can be improved.

Examples of the solid content of the thermoplastic emulsion resin include emulsion particles of a thermoplastic resin such as acrylic resin, urethane resin, vinyl acetate-based copolymer, urethane acrylic composite particles, styrene-butadiene rubber (SBR), and nitrile rubber (NBR). Can be mentioned. Among these, urethane acrylic composite particles are preferable. In the present specification, the urethane-acrylic composite particles mean those having a heterogeneous structure of an acrylic resin and a urethane resin in a single particle.

Since each of the urethane resin and the acrylic resin has high adhesive strength with the core material layer 129, good adhesive strength with the core material layer 129 can be exhibited by using urethane acrylic composite particles. Further, the urethane resin is particularly excellent in toughness, elasticity and flexibility, and the acrylic resin is particularly excellent in transparency, durability, weather resistance, chemical resistance and film forming property.

Further, in the present specification, the “heterogeneous structure” means a structure in which a plurality of phases made of different types of resins exist in one particle, and examples thereof include a core-shell structure, a localized structure, and a sea-island structure. Be done.

As the solid content of the thermoplastic emulsion resin, one containing one of these alone may be used, or one containing a mixture of two or more different types of thermoplastic resins may be used. ..

Further, the solid content of the thermoplastic emulsion resin may contain, if necessary, a small amount of a thickener, a penetration accelerator, an antifoaming agent, or the like, in addition to the emulsion particles of the thermoplastic resin.

The solid content of the thermoplastic emulsion resin preferably contains emulsion resin particles having an average particle size of 30 to 100 nm, and more preferably the average particle size of the emulsion resin particles is 60 to 90 nm. As a result, the impregnation property between the fibers of the surface layer base material is improved, and the inside of the surface layer base material can be further impregnated, so that good flexibility can be imparted to the surface layer 120.

The method of supporting the solid content of the thermoplastic emulsion resin on the second surface 102 side of the printing base material 122 is not particularly limited, and the resin (A) is supported on the first surface 101 side of the printing base material 122 as described above. It can be done in the same way as the method. That is, a method of applying a thermoplastic emulsion resin in an emulsion state dissolved in a solvent and heating and drying it can be mentioned.

The solvent used for the thermoplastic emulsion resin is not particularly limited, and examples thereof include water. Further, a poor solvent may be used as long as it does not adversely affect the substance. The solid content of the thermoplastic emulsion resin (all components excluding the solvent) is not particularly limited, but is preferably 25 to 60% by mass, more preferably 30 to 45% by mass of the thermoplastic emulsion resin. Thereby, the impregnation property of the thermoplastic emulsion resin into the base material can be improved.

The first resin layer 123 and the second resin layer 124 do not have to form a layer independently. That is, the resin (A) and the resin (B) may be supported on the printing substrate 122. Here, when the printing base material 122 supports the resin, the resin adheres to the surface of the base material (carrier) or is impregnated in the voids inside the base material, and the resin is carried after molding the surface layer material. It means that it is in a state that enables the expression of performance. The first resin layer 123 and the second resin layer 124 have a layered distribution in the surface layer 120, for example. The resin does not have to be uniformly distributed on the surface of the base material and inside the base material.

The core material layer 129 is composed of, for example, a glass cloth or a prepreg based on the glass cloth. Thereby, heat resistance, nonflammability, rigidity and the like can be imparted to the decorative layer 12.

The thickness of the core material layer 129 is preferably 50 μm or more. As a result, sufficient heat resistance and nonflammability can be imparted to the decorative layer 12. The upper limit of the thickness is not particularly limited, but the larger the thickness, the larger the thickness and weight of the decorative layer 12, and the higher the cost. Therefore, it should be set within an allowable range in the design of the final product. Is preferable, and the thickness is preferably 350 μm or less.

The magnet layer 14 is fixed to the second surface 102 side of the decorative layer 12. When the decorative material 10 includes the magnet layer 14, the decorative material 10 can be detachably attached to the base 20 containing the ferromagnet. Further, the decorative material 10 can be attached to the base 20 without using a solvent at the construction site. The magnetic flux density of the magnet layer 14 is preferably 20 mT or more so that the decorative material 10 is sufficiently strongly fixed to the base 20. Further, it is preferable that the magnet layer 14 is provided in a region of 75% or more when viewed from a direction perpendicular to the main surface of the decorative material 10.

The magnet layer 14 is a layer formed by bonding magnet powder with a binder (bonding resin), and is, for example, a magnet sheet. The magnet powder is preferably one having excellent magnetic properties. Examples of such magnet powder include alloys containing R (where R is at least one of the rare earth elements containing Y), particularly R (where R is at least one of the rare earth elements containing Y). (1), TM (where TM is at least one of the transition metals) and B (boron) are included in the alloy.

The binder contained in the magnet layer 14 may be either a thermoplastic resin or a thermosetting resin. Examples of the thermoplastic resin include polyamides (eg, nylon 6, nylon 46, nylon 66, nylon 610, nylon 612, nylon 11, nylon 12, nylon 6-12, nylon 6-66, nylon 6T, nylon 9T). Liquid crystal polymers such as thermoplastic polyimide and aromatic polyester, polyolefins such as polyphenylene oxide, polyphenylene sulfide, polyethylene, polypropylene, ethylene-vinyl acetate copolymer, modified polyolefin, polycarbonate, polymethylmethacrylate, polyethylene terephthalate, polybutylene terephthalate, etc. Examples thereof include polyesters, polyethers, polyether ether ketones, polyetherimides, polyetherimides, etc., or copolymers, blends, polymer alloys, etc. mainly containing these, and one or more of these are mixed. Can be used.

Examples of the thermosetting resin include various epoxy resins such as bisphenol type, novolak type and naphthalene type, phenol resin, urea resin, melamine resin, polyester (unsaturated polyester) resin, polyimide resin, silicone resin and polyurethane resin. These can be mentioned, and one or a mixture of two or more of these can be used. The thermosetting resin (uncured) used may be liquid at room temperature or solid (powdered).

The thickness (average thickness) of the magnet layer 14 is appropriately changed from an aesthetic point of view, but is preferably 0.15 to 6 mm, more preferably 0.6 to 2 mm. The size and shape of the magnet layer 14 can be appropriately changed depending on the shape of the decorative material 10 and the like.

The magnet layer 14 is fixed to the decorative layer 12 by the adhesive layer 13. The adhesive layer 13 is not particularly limited, but is mainly composed of, for example, an adhesive. Examples of this pressure-sensitive adhesive include rubber-based pressure-sensitive adhesives, acrylic-based pressure-sensitive adhesives, and silicone-based pressure-sensitive adhesives.

As the acrylic pressure-sensitive adhesive, a polymer mainly composed of a low Tg main monomer component that gives adhesiveness, a high Tg comonomer component that gives adhesiveness and cohesiveness, and a functional group-containing monomer component for cross-linking and adhesiveness improvement. Or it consists of a copolymer.

Examples of the main monomer component include acrylic acid alkyl esters such as ethyl acrylate, butyl acrylate, amyl acrylate, 2-ethylhexyl acrylate, octyl acrylate, cyclohexyl acrylate, and benzyl acrylate, and butyl methacrylate and methacrylic acid. Examples thereof include methacrylic acid alkyl esters such as 2-ethylhexyl acid, cyclohexyl methacrylate, and benzyl methacrylate.

Examples of the comonomer component include methyl acrylate, methyl methacrylate, ethyl methacrylate, vinyl acetate, styrene, acrylonitrile and the like.

Examples of the functional group-containing monomer component include carboxyl group-containing monomers such as acrylic acid, methacrylic acid, maleic acid, and itaconic acid, 2-hydroxyethyl (meth) acrylic acid, and 2-hydroxypropyl (meth) acrylic acid. , N-methylol acrylamide and other hydroxyl group-containing monomers, acrylamide, methacrylic acid, glycidyl methacrylate and the like.

Examples thereof include those mainly containing block copolymers.

Further, examples of the silicone-based pressure-sensitive adhesive include dimethylsiloxane-based adhesives and diphenylsiloxane-based adhesives.

As the adhesive as described above, either a non-crosslinked type or a crosslinked type can be used. In the latter case, a cross-linking agent can be added if necessary. Examples of the cross-linking agent include epoxy compounds, isocyanato compounds, metal chelate compounds, metal alkoxides, metal salts, amine compounds, hydrazine compounds, aldehyde compounds and the like. Such an adhesive may be either an organic solvent type or an emulsion type.

Further, various additives such as a plasticizer, a tackifier, a thickener, a filler, an antiaging agent, a preservative, an antifungal agent, a dye, and a pigment are added to the adhesive layer 13 as needed. You may.

In addition, when the core material layer 129 is impregnated with an adhesive, the core material layer 129 may also serve as the adhesive layer 13. Further, the decorative layer 12 may further have a protective layer. The protective layer can be provided so as to be exposed on the first surface 101.

The method for producing the decorative material 10 will be described below. The decorative material 10 is formed by fixing the magnet layer 14 to the decorative layer 12 via the adhesive layer 13. Specifically, an adhesive or the like constituting the adhesive layer 13 is applied to the decorative layer 12, and the magnet layer 14 is laminated. However, the magnet layer 14 coated with the adhesive may be laminated on the decorative layer 12.

The decorative layer 12 is obtained by superimposing the surface layer 120 and the core material layer 129, molding them under heat and pressure, and laminating them. Further, by stacking a predetermined plate material at the time of molding the decorative layer 12, the surface roughness of the first surface 101 of the decorative material 10, the reflectance of light, and the like can be adjusted, and the design can be improved.

The surface layer 120 is obtained as follows. First, the printing portion 121 is formed by printing a design such as a pattern on the printing base material 122. Next, the first resin layer 123 is formed on one surface of the printing substrate 122 provided with the printing portion 121, and the second resin layer 124 is formed on the other surface.

The method for producing the decorative material 10 is not limited to the above method. For example, a carrier film may be used if necessary. The carrier film is used to protect any layer during production or to facilitate production. The carrier film is not included in the decorative material 10 by being subsequently removed.

Further, in this figure, an example in which the printing unit 121 is located inside the decorative layer 12 is shown, but the printing unit 121 may be located on the surface of the decorative layer 12 on the first surface 101 side.

The structure of the decorative material 10 is not limited to the above example. The decorative material 10 is, for example, cloth, linen, cotton, silk or other cloth, plastic resin such as vinyl chloride, PET or polyolefin, metal (foil) such as SUS or aluminum, paper such as corrugated cardboard, wood, bamboo or rattan. It can be composed of one or more of the materials.

The construction method according to the present embodiment includes a step of fixing the base 20 to the structural member (framework) of the wall such as the skeleton 30, and a step of fixing the decorative material 10 to the base 20 by magnetic force. In the step of fixing the base 20, a plurality of plate members are attached to the structural member with a stapler, screws, or the like so as to cover almost the entire wall surface to form the first base layer 22. Next, a plurality of plate materials are attached to the first base layer 22 with staplers, screws, or the like so as to cover almost the entire first base layer 22, and the second base layer 24 is formed. For example, the second base layer 24 is a ferromagnetic layer. Then, putty 201 is applied to the boundaries between the plurality of plate materials constituting the second base layer 24 to fill the gaps and even out the steps. Next, in the step of fixing the decorative material 10 to the base 20 by a magnetic force, the magnet layer 14 of the decorative material 10 is directed to the base 20 side, and the decorative material 10 is attached to the base 20.

If the decorative material 10 is to be replaced, the decorative material 10 may be peeled off from the base 20 and a new decorative material 10 may be attached to the base 20.

In addition, another sheet material may be sandwiched between the ferromagnetic layer of the base 20 and the decorative material 10. By doing so, even while the decorative material 10 is unavoidably removed, the design property is not lost. Examples of the sheet material include a resin sheet such as a vinyl chloride sheet and paper. The sheet material may be attached so as to form, for example, the outermost surface of the base 20 (the surface closest to the decorative material 10) as a part of the base 20, or is sandwiched between the base 20 and the decorative material 10. You may. Further, instead of providing the sheet material, a coating film made of paint may be formed on the outermost surface of the base 20. Even in that case, the same effect can be obtained.

When the weight of the decorative material 10 is large, the decorative material 10 may be fixed to the base 20 not only by magnetic force but also by using physical supporting means.

The construction method according to the present embodiment can be realized by using an interior or exterior construction set including a base material containing a ferromagnetic material and a decorative material 10 including a magnet material 14. In the present embodiment, the base material containing a ferromagnetic material is a member constituting the ferromagnetic layer, and is a plate material containing the above-mentioned ferromagnetic material. If the decorative material 10 is to be replaced, only the decorative material 10 needs to be newly prepared separately.

Next, the operation and effect of this embodiment will be described. According to the present embodiment, by attaching a decorative material provided with a magnet material to a base containing a ferromagnet, it is possible to realize a wall structure that can be easily replaced in a short time when the decorative material is desired to be replaced.

Further, since it is not necessary to use an adhesive at the construction site, the decorative material can be attached in a short time, and the problem of odor due to an organic solvent or the like can be avoided.

(Second Embodiment)
FIG. 4 is a diagram for explaining a construction method according to the second embodiment. This figure shows a cross section of a wall constructed by the method of this embodiment. The construction method according to the first embodiment is the same as the construction method according to the first embodiment, except that the ferromagnetic layer is a solidified material of a paint containing a ferromagnetic material. This will be described in detail below.

In the construction method according to the present embodiment, the base 20 includes a first base layer 22, a second base layer 24, and a third base layer 26. The third base layer 26 is a solidified material of a paint containing a ferromagnetic material, and is a ferromagnetic layer. The solidified material of the paint is a solid obtained by solidifying or curing the paint. In the present embodiment, the first base layer 22 and the second base layer 24 do not have to contain a ferromagnet. That is, the first base layer 22 and the second base layer 24 may be an inorganic board such as a caucal board, a gypsum board, a volcanic vitreous multi-layer board, or a wooden plywood. The third base layer 26 is formed by applying a paint containing a ferromagnetic material to the other base layer and solidifying or curing the paint.

In the present embodiment, in the step of fixing the base 20 to the structural member (framework) of the wall, the first base layer 22 and the second base layer 24 are formed and the putty 201 is applied in the same manner as in the method of the first embodiment. After that, a paint containing a ferromagnetic material (hereinafter, also simply referred to as “paint”) is applied to the surface of the second base layer 24. The third base layer 26 is formed by drying the paint. Next, the step of fixing the decorative material 10 to the base 20 by a magnetic force is performed in the same manner as in the first embodiment.

It should be noted that the first base layer 22 and the second base layer 22 and the second base plate material are used in which a paint containing a ferromagnetic material is previously applied to a plate material such as a caucal board, a gypsum board, or a wooden plywood, and the solidified material of the paint is formed by drying. At least one of the base layers 24 may be formed. By doing so, it is not necessary to dry the paint at the construction site, and the generation of odor can be avoided. Moreover, it is not necessary to provide a drying time, and the construction can be performed in a short time.

The paint is preferably applied so as to cover the entire second base layer 24, but may be applied so as to cover only a part of the second base layer 24. The area of the area coated with the paint is not particularly limited with respect to the area of the entire base 20 when viewed from the direction perpendicular to the main surface of the base 20, but is preferably 20% or more, preferably 50% or more. More preferred. For example, the base 20 may be painted so as to draw a grid. Further, it is preferable to apply a paint to the region of the base 20 facing the outer periphery of each decorative material 10.

Paints include ferromagnetic materials and binders. The ferromagnetic material is a ferromagnetic powder such as iron powder. The size of the particles is not particularly limited, but the median diameter D ₅₀ of the ferromagnetic powder is preferably 0.02 mm or more and 0.2 mm or less, and more preferably 0.05 mm or more and 0.1 mm or less. Then, it becomes easy to apply the paint uniformly. The content of the ferromagnetic powder in the solid material of the coating material is preferably 50% by mass or more and 90% by mass or less, and more preferably 60% by mass or more and 80% by mass or less. Then, the decorative material 10 can be fixed to the base 20 with a sufficient magnetic force.

Examples of the binder contained in the paint include the same resin as the resin exemplified as the binder contained in the magnet layer 14.

Further, the coating material may contain a solvent, a plasticizer, a dispersant, a thickener, and other additives in addition to the ferromagnetic material and the binder. The total content of these additives is, for example, 5% by weight or less based on the solidified material of the paint.

The paint is obtained by mixing each of the above components.

The construction method according to the present embodiment can be realized by using an interior or exterior construction set including a base material containing a ferromagnetic material and a decorative material 10 including a magnet material 14. In the present embodiment, the base material containing a ferromagnetic material is a paint containing a ferromagnetic material or a base plate material on which a solidified material of the paint containing a ferromagnetic material is formed.

Next, the operation and effect of this embodiment will be described. According to the present embodiment, by attaching a decorative material provided with a magnet material to a base containing a ferromagnet, it is possible to realize a wall structure that can be easily replaced in a short time when the decorative material is desired to be replaced. Further, by applying a paint, a base material containing a ferromagnet can be easily prepared, and it can be easily applied to a curved wall surface or the like.

Although the embodiments of the present invention have been described above with reference to the drawings, these are examples of the present invention, and various configurations other than the above can be adopted.
