  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate. “˜” represents “from” to “below” unless otherwise specified.

(First embodiment)
1 and 2 are diagrams for explaining a 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 a 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 including a magnet material 14 is attached to a base 20 including a ferromagnetic material.

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

  The construction method of this embodiment is a method of constructing an inner wall or an outer wall such as a room or a passage. Although it does not specifically limit as a building which constructs interior or exterior, a building, a house, etc. are mentioned.

  The decorative material 10 is a member that is integrated with the wall and imparts an aesthetic appearance to the wall. 1 and 2 show an example in which the magnet material 14 is a sheet-like magnet layer. Hereinafter, the magnet material 14 will be described as a magnet layer 14, but the magnet material 14 is not limited to a sheet shape, It may be a lump. 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 a sheet shape or a plate shape. 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 housing 30 is covered with the decorative material 10. In the example of FIGS. 1 and 2, the base 20 has a plurality of base layers. The foundation 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 a wall frame is fitted so as to be located inside the wall relative to the decorative material 10. The base layer alone or in combination with each other exhibits functions such as structural reinforcement, heat insulation, moisture proofing, waterproofing, and fire resistance. In the example 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 foundation 20 is fixed to the housing 30.

  The housing 30 is, for example, a building housing and is a framework that supports the structure of the building. The housing 30 is made of wood, metal, reinforced concrete, or the like. In addition, the foundation | substrate 20 does not necessarily need to be fixed to the housing 30 of a building. For example, the laminate of the base 20 and the decorative material 10 may be a part of a partition that divides an indoor space. Further, the decorative material 10 may function as a corner material with a corner, a parting material, a joiner, a display panel, or the like.

  The base 20 includes a ferromagnetic material, and a magnet is attracted to the base 20. The ferromagnetic material is, for example, iron. In the present embodiment, the base 20 includes a ferromagnetic layer including a ferromagnetic material. For example, at least one of the second underlayer 24 and the first underlayer 22 is a ferromagnetic layer. Here, it is preferable that the base layer closest to the decorative material 10 among the base 20 is a ferromagnetic layer. Then, 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 a calcium (calcium silicate) board, a gypsum board, and a volcanic glassy multilayer board, and wooden plywood.

  In the present embodiment, the ferromagnetic layer is a plate material including a ferromagnetic material. The plate material including the ferromagnetic material is a ferromagnetic plate such as an iron plate. The plate material containing a ferromagnetic material may be a composite member of a material other than a ferromagnetic material and a ferromagnetic material such as iron powder or iron foil. By using the composite member, it is possible to improve the degree of freedom of shape and reduce the weight. Examples of the material other than the ferromagnetic material include resin, wood, gypsum, calcium silicate, cement, and glassy material. 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 and the like and iron powder and forming them into a plate shape. Or a composite member is obtained by laminating | stacking and adhere | attaching the plate-shaped member and iron foil of materials other than a ferromagnetic material. Further, when the base layer is formed of a soil wall, a composite member may be formed by forming a layer using soil mixed with a ferromagnetic material. Although the thickness of a ferromagnetic material layer is not specifically limited, For example, they are 1 mm or more and 20 mm or less.

  The base 20 only needs to include a ferromagnetic material in at least a part of the region as viewed from a direction perpendicular to the main surface, and does not need to include a ferromagnetic material as a whole. The area of the region including the ferromagnetic material with respect to the entire area of the base 20 is not particularly limited, but is preferably 20% or more, and more preferably 50% or more. For example, the underlayer 20 may include a ferromagnetic layer patterned in a lattice pattern. Moreover, it is preferable that the ferromagnetic material is contained in the area | region which opposes the outer periphery of each decorative material 10 among the foundation | substrates 20. FIG.

  By including the ferromagnetic material in the base 20, 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, the decorative material 10 is detachable from the base 20, so that the base 20 can be used when the decorative material 10 is 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 surface. Moreover, it is not necessary to use an adhesive when fixing the decorative material to the ground at the construction site. Therefore, no odor due to an organic solvent or the like is generated during drying. Furthermore, 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, each of the first base layer 22 and the second base layer 24 may be formed of a plurality of plate materials. Here, it is preferable that the boundary between the plurality of plate members in the first underlayer 22 and the boundary between the plurality of plate members in the second underlayer 24 do not overlap each other except for an intersection. By doing so, it is avoided that the fire leaks and spreads from the boundary portion at the time of fire, and fire resistance is improved.

  Further, in the second foundation layer 24 that is the foundation layer closest to the decorative material 10, the boundaries of the plurality of plate materials are filled with putty 201. In addition, the level difference generated at the boundary between the plate material and the plate material is leveled approximately flat by the putty 201.

  The decorative material 10 is fixed to the base 20 with a magnetic force. A plurality of decorative materials 10 may be spread on one wall surface. If it does so, conveyance of the cosmetics 10 to a construction place will become easy. When a plurality of decorative materials 10 are arranged and fixed on the wall surface, a gap may be provided between the decorative material 10 and the decorative material 10. Then, even when the decorative material 10 expands and contracts due to moisture or the like, the decorative material 10 is unlikely to bend. However, when the entire decorative material 10 is made of a material that is difficult to expand and contract, such as a resin, 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 two or more openings. Since the plate material has the opening, the weight of the base 20 can be reduced, and the earthquake 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 members constituting the other underlayer.

  FIG. 3 is a cross-sectional view illustrating the configuration of the decorative material 10 according to the first embodiment. The cosmetic 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. Although the structure of the decorative layer 12 is not particularly limited, the decorative material 10 includes a surface layer 120 and a core material layer 129 in the present embodiment. The decorative layer 12 is made of, for example, a melamine resin, a solid content of a thermoplastic emulsion resin, polyvinyl chloride, polyvinyl fluoride, polyvinylidene fluoride, polyester, polytetrafluoroethylene, a polyolefin resin, and a (meth) acrylic resin. It comprises 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. Furthermore, the surface layer 120 is configured to include a printing substrate 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 may not include the printing base material 122 and the printing unit 121. For example, the surface layer 120 may have a design property by including a resin layer or a metal layer that is uneven by embossing. In addition, a design may be applied to the surface of the first surface 101 of the decorative material 10.

  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 such a degree of flexibility that it does not crack when it is bent at a bending radius of 10 mm at 25 ° C.

  The decorative layer 12 is a part that imparts design properties to the wall surface. The decorative layer 12 has a design property that causes aesthetics when viewed from the first surface 101 side. In the example of this figure, the decorative layer 12 is configured so that the printed portion 121, that is, the design such as the printed pattern can be visually recognized from the first surface 101 side.

  The surface layer 120 carries, for example, a resin (first resin layer 123) containing a melamine resin on the first surface 101 side serving as a design surface, and is formed of a thermoplastic emulsion resin on the second surface 102 side in contact with the core material layer 129. It is made of a surface layer material composed of a printing base material 122 that carries 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. The printing substrate 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 properties to the decorative material 10. The printing unit 121 is ink carried on the printing substrate 122 by printing. The printing unit 121 may be formed in a layer on the surface of the printing substrate 122, or at least a part of the printing unit 122 may be impregnated in the printing substrate 122. The printing method is not particularly limited, and gravure printing, inkjet printing, offset printing, and the like can be used.

  The first resin layer 123 is a layer containing a resin (A), and is a transparent layer located on the first surface 101 side of the printing substrate 122. Resin (A) contains a melamine resin. The resin (A) preferably contains a melamine resin. Thereby, the surface of the decorative material 10 contains a melamine resin, and suitable hardness can be imparted to the surface of the decorative layer 12. As a result, the durability of the decorative material 10 can be enhanced. 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 resin obtained by reacting melamine and formaldehyde in a neutral or weak alkali can be used.

  Moreover, as a melamine resin, a commercially available thing, such as a melamine resin by Sumitomo Chemical Co., Ltd., can also be used.

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

  It does not specifically limit as a solvent which melt | dissolves resin (A), For example, water, methanol, etc. are mentioned. Of these, water is preferred. Moreover, you may use a poor solvent in the range which does not exert a bad influence. The solid content of the resin varnish (all components except the solvent) is not particularly limited, but is preferably 30 to 70% by mass of the resin varnish, and more preferably 45 to 60% by mass. Thereby, the impregnation property to the base material of the resin varnish can be improved.

  The second resin layer 124 is a layer containing a resin (B). Resin (B) is, for example, a solid content of a thermoplastic emulsion resin. In the present specification, the thermoplastic emulsion resin is an emulsion in which the thermoplastic resin is dispersed in a solvent. 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 includes components present 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 Bending workability can be improved.

  Examples of the solid content of the thermoplastic emulsion resin include emulsion particles of thermoplastic resin such as acrylic resin, urethane resin, vinyl acetate copolymer, urethane acrylic composite particles, styrene butadiene rubber (SBR), and nitrile rubber (NBR). Is 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 expressed by using urethane acrylic composite particles. Furthermore, 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.

  In the present specification, “heterophasic structure” means a structure in which a plurality of phases composed 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. It is done.

  In addition, as solid content of a thermoplastic emulsion resin, the thing in which one type of these is contained independently can also be used, and the thing containing a mixture of 2 or more types of different thermoplastic resins can also be used. .

  In addition to the thermoplastic resin emulsion particles, the solid content of the thermoplastic emulsion resin may contain a small amount of a thickening agent, a penetration accelerator, an antifoaming agent, and the like as necessary.

  The solid content of the thermoplastic emulsion resin preferably includes emulsion resin particles having an average particle size of 30 to 100 nm, and the average particle size of the emulsion resin particles is more preferably 60 to 90 nm. Thereby, since the impregnation property between the fibers of the surface layer base material is improved and the surface layer base material can be more impregnated, good flexibility can be imparted to the surface layer 120.

  The method for supporting the solid content of the thermoplastic emulsion resin on the second surface 102 side of the printing substrate 122 is not particularly limited, and the above-described method for supporting the resin (A) on the first surface 101 side of the printing substrate 122. It can be performed in the same manner as the method. That is, a method of coating and heat-drying a thermoplastic emulsion resin in an emulsion state dissolved in a solvent can be mentioned.

  It does not specifically limit as a solvent used for a thermoplastic emulsion resin, For example, water etc. are mentioned. Moreover, you may use a poor solvent in the range which does not exert a bad influence. 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 to the base material of a thermoplastic emulsion resin can be improved.

  In addition, the 1st resin layer 123 and the 2nd resin layer 124 do not need to form the layer independently. That is, the resin (A) and the resin (B) may be carried on the printing substrate 122. Here, the printing base material 122 carrying the resin means that the resin adheres to the surface of the base material (carrier) or is impregnated in the voids inside the base material, and the resin carried after the molding of the surface layer material. It means a state in which performance can be expressed. For example, the first resin layer 123 and the second resin layer 124 have a layered distribution in the surface layer 120. In addition, resin does not need to be uniformly distributed on the surface of a base material and the inside of a base material.

  The core material layer 129 includes, for example, a glass cloth or a prepreg having a glass cloth as a base material. Thereby, heat resistance, incombustibility, rigidity, etc. can be provided to the decorative layer 12.

  The thickness of the core material layer 129 is preferably 50 μm or more. Thereby, 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 greater the thickness and weight of the decorative layer 12, and the higher the cost. Therefore, the upper limit of the thickness should be set within the allowable range in the design of the final product. Is preferably 350 μm or less.

  The magnet layer 14 is fixed to the second surface 102 side of the decorative layer 12. Since the decorative material 10 includes the magnet layer 14, the decorative material 10 can be detachably attached to the base 20 including the ferromagnetic material. Further, the decorative material 10 can be attached to the base 20 without using a solvent at the construction site. It is preferable that the magnetic flux density of the magnet layer 14 is 20 mT or more so that the decorative material 10 is sufficiently firmly fixed to the base 20. Moreover, it is preferable that the magnet layer 14 is provided in an area of 75% or more when viewed from a direction perpendicular to the main surface of the decorative material 10.

Examples of such magnet powder include alloys containing R (where R is at least one of rare earth elements including Y), particularly R (where R is at least one of rare earth elements including Y). 1 type) and TM (wherein TM is at least one of transition metals) and B (boron) are included.

  The binder contained in the magnet layer 14 may be either a thermoplastic resin or a thermosetting resin. Examples of the thermoplastic resin include polyamide (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 crystalline polymers such as thermoplastic polyimide and aromatic polyester, polyphenylene oxide, polyphenylene sulfide, polyolefin such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, modified polyolefin, polycarbonate, polymethyl methacrylate, polyethylene terephthalate, polybutylene terephthalate, etc. Polyester, polyether, polyetheretherketone, polyetherimide, polyacetal, etc., or copolymers, blends and polymers based on these Roy and the like, can be used as a mixture of two or more of them.

  Examples of the thermosetting resin include various epoxy resins such as bisphenol type, novolac type, naphthalene type, phenol resin, urea resin, melamine resin, polyester (unsaturated polyester) resin, polyimide resin, silicone resin, polyurethane resin, and the like. 1 type or 2 types or more of these can be mixed and used. The thermosetting resin (uncured) used may be liquid at room temperature or solid (powdered).

  Although the thickness (average thickness) of the magnet layer 14 is appropriately changed from an aesthetic point of view, it is preferably 0.15 to 6 mm, and 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. Although the adhesive layer 13 is not specifically limited, For example, it is mainly comprised with the adhesive. Examples of the pressure-sensitive adhesive include a rubber-based pressure-sensitive adhesive, an acrylic pressure-sensitive adhesive, and a silicone-based pressure-sensitive adhesive.

  Acrylic pressure-sensitive adhesives include a polymer mainly composed of a low Tg main monomer component that provides tackiness, a high Tg comonomer component that provides adhesiveness and cohesion, and a functional group-containing monomer component for crosslinking and adhesion improvement. Or it consists of a copolymer.

  Note that the core material layer 129 may also serve as the adhesive layer 13 when the core material layer 129 is impregnated with an adhesive. 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.

  A method for manufacturing 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 an adhesive may be laminated on the decorative layer 12.

  The decorative layer 12 is obtained by superposing the surface layer 120 and the core material layer 129, and laminating them by heating and pressing. In addition, when the decorative layer 12 is molded, by overlapping a predetermined plate material, the surface roughness of the first surface 101 of the decorative material 10, the light reflectance, and the like can be adjusted, and the design can be improved.

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

  In addition, the manufacturing method of the decorative material 10 is not limited to an above-described method. For example, you may use a carrier film as needed. 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 removed thereafter.

  Moreover, although the printing part 121 showed the example located in the inside of the decorative layer 12 in this figure, the printing part 121 may be located in the surface by the side of the 1st surface 101 of the decorative layer 12. FIG.

  The structure of the decorative material 10 is not limited to the above example. The decorative material 10 is made of cloth, linen, cotton, silk, etc., plastic resin such as vinyl chloride / PET / polyolefin, metal (foil) such as SUS / aluminum, paper such as cardboard, wood, bamboo, rattan, etc. One or more of these materials can be included.

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

  If it is desired to replace the decorative material 10, 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.

  Note that another sheet material may be sandwiched between the ferromagnetic layer of the base 20 and the decorative material 10. By doing so, it is unavoidable that the design property is not lost while the decorative material 10 is in a removed state. Examples of the sheet material include resin sheets such as vinyl chloride sheets 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. May be. Further, instead of providing a sheet material, a paint film made of a paint may be formed on the outermost surface of the base 20. Even in that case, the same effect can be obtained.

  In addition, when the weight of the decorative material 10 is large, the decorative material 10 may be fixed to the base 20 by further using physical support means as well as fixing by magnetic force.

  The construction method according to the present embodiment can be realized using an interior or exterior construction set including a base material including a ferromagnetic material and a decorative material 10 including a magnet material 14. In the present embodiment, the base material including the ferromagnetic material is a member constituting the ferromagnetic layer, and is a plate material including the above-described ferromagnetic material. When it is desired to replace the decorative material 10, 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, a wall structure that can be easily replaced in a short time can be realized by attaching a decorative material including a magnet material to a base including a ferromagnetic material when the decorative material is to be replaced.

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

  In the construction method according to the present embodiment, the foundation 20 includes a first foundation layer 22, a second foundation layer 24, and a third foundation layer 26. The third underlayer 26 is made of a solidified paint containing a ferromagnetic material and is a ferromagnetic layer. The solidified product of the paint is a solid obtained by solidifying or curing the paint. In the present embodiment, the first underlayer 22 and the second underlayer 24 do not need to contain a ferromagnetic material. That is, the 1st foundation layer 22 and the 2nd foundation layer 24 may be inorganic boards, a wooden plywood, etc., such as a calc board, a gypsum board, and a volcanic glassy multilayer board. The third underlayer 26 is formed by applying a paint containing a ferromagnetic material to the other underlayer and solidifying or curing it.

  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 as in the method of the first embodiment. After that, the surface of the second underlayer 24 is coated with a paint containing a ferromagnetic material (hereinafter also simply referred to as “paint”). The third ground layer 26 is formed by drying the paint. Next, as in the first embodiment, a step of fixing the decorative material 10 to the base 20 with a magnetic force is performed.

  Note that the first base layer 22 and the second base layer 22 and the second base material are formed using a base plate material in which a coating material containing a ferromagnetic material is applied in advance to a plate material such as a calcium plate, a plaster board, and a wooden plywood, and dried to form a solidified product of the paint. At least one of the foundation layers 24 may be formed. If it does so, it is not necessary to dry a coating material in a construction place, and generation | occurrence | production of an 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 region where the paint is applied with respect to the entire area of the base 20 as viewed from the direction perpendicular to the main surface of the base 20 is not particularly limited, but is preferably 20% or more, and more preferably 50% or more. More preferred. For example, the base 20 may be coated with paint so as to draw a lattice. Moreover, it is preferable to apply a paint to the area | region which opposes the outer periphery of each decorative material 10 among the foundation | substrates 20.

The paint includes a ferromagnetic material and a binder. The ferromagnetic material is a ferromagnetic powder such as iron powder. Is not particularly limited the size of the particle, the median diameter _{D 50} of the ferromagnetic powder is 0.2mm or less are preferred over 0.02 mm, more preferably 0.05mm or 0.1mm or less. If it does so, it will become easy to apply | coat a coating material uniformly. The content of the ferromagnetic powder in the solid material of the coating 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 resins as those exemplified as the binder contained in the magnet layer 14.

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

  The paint is obtained by mixing the above-described components.

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

  Next, the operation and effect of this embodiment will be described. According to the present embodiment, a wall structure that can be easily replaced in a short time can be realized by attaching a decorative material including a magnet material to a base including a ferromagnetic material when the decorative material is to be replaced. In addition, a base including a ferromagnetic material can be easily prepared by applying a paint, and can be easily applied to a curved wall surface or the like.
