(First embodiment)
Drawing 1 is a figure for explaining the construction method of the cosmetics concerning a 1st embodiment. This figure has shown the cross section of the wall constructed by the method of this embodiment. FIG. 2 is a diagram illustrating the configuration of the decorative material 10 according to the first embodiment. This construction method includes a step of attaching the second decorative material 10b to the design surface 101a of the first decorative material 10a attached to the base 20. The second decorative material 10b includes a decorative layer 12, and a magnet member 14 provided on the opposite side of the design surface 101b of the second decorative material 10b with respect to the decorative layer 12. Further, a ferromagnetic material is contained in the base 20 or between the base 20 and the design surface 101a of the first decorative material 10a. In the attaching step, the second decorative material 10b is attached using the magnetic force of the magnet member 14. 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 of a room, a passage, or an elevator, for example. Although it does not specifically limit as a building which constructs interior or exterior, a building, a house, etc. are mentioned. Moreover, this construction method may be a method of constructing a decorative material on the surface of a moving object, furniture, or the like.

  In this embodiment, the 1st decorative material 10a and the 2nd decorative material 10b have a structure like the decorative material 10 demonstrated below, for example. However, the 1st decorative material 10a and the 2nd decorative material 10b may have the same structure, and may have a different structure. Note that the first decorative material 10 a may not include the magnet layer 14 and may not include the adhesive layer 13. In that case, the first decorative material 10a is fixed to the base 20 with an adhesive or the like.

  The decorative material 10 is a member that is integrated with a wall or the like to give a beautiful appearance. FIG. 2 shows an example in which the magnet member 14 is a sheet-like magnet layer. In the following description, the magnet member 14 is described as the magnet layer 14. However, the magnet member 14 is not limited to a sheet shape, but is a lump shape. May be. The decorative material 10 is configured such that a pattern or design such as wood grain is visible from the design surface 101 side.

  In the construction method according to the present embodiment, the second decorative material 10b is attached to the design surface 101a of the first decorative material 10a. Therefore, it is not necessary to peel off the first decorative material 10a from the base 20 when dirt is attached to the first decorative material 10a, when scratches are generated, or when it is desired to redesign the design. In addition, the appearance of the structure can be renewed. Moreover, the burden concerning storage and disposal of the peeled first decorative material 10a is also reduced. Furthermore, since the second decorative material 10b is adsorbed by magnetic force, the replacement is easy even when the appearance of the structure is renewed.

  From the viewpoint of increasing the attractive force to the base 20, the magnet layer 14 is preferably provided on substantially the entire surface as viewed from the direction perpendicular to the design surface 101 of the decorative material 10. Moreover, it is more preferable that the magnet layer 14 is uniformly provided on the surface opposite to the design surface 101 of the decorative material 10. If it does so, it will be avoided that the cosmetic material 10 floats from the base | substrate 20, or bends. Moreover, even if the planar shape of the decorative material 10 is processed, the attachment / detachment function of the decorative material 10 to the base 20 can be secured. Note that the magnet layer 14 being provided on almost the entire surface of the decorative material 10 means that the magnet layer 14 is provided in an area of 90% or more as viewed from a direction perpendicular to the main surface of the decorative layer 12, for example.

  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.

  FIG. 3 is a perspective view of the wall on which the second decorative material 10b is constructed, and a portion of the base 20, the first decorative material 10a, and the second decorative material 10b is omitted.

  The first decorative material 10a and the second decorative material 10b are 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 first decorative material 10a and the second decorative material 10b. In the example of FIGS. 1 and 3, the base 20 has a plurality of base layers. The foundation layer is a layer located between the frame of the wall and the first decorative material 10a. Alternatively, the base layer is a layer that is fitted into the frame of the wall so as to be located inside the wall relative to the first decorative material 10a. 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 3, 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.

  In the construction method according to the present embodiment, the base 20 includes a ferromagnetic material. Then, the magnet is attracted to the base 20. Examples of the ferromagnetic material include iron, cobalt, nickel, and alloys thereof. 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. If it does so, the fixed strength of the 2nd decorative material 10b with respect to the foundation | substrate 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 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.

  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.

  The ferromagnetic layer may be a solidified product of a paint containing a ferromagnetic material. The solidified product of the paint is a solid obtained by solidifying or curing the paint. In this case, a ferromagnetic layer can be formed by applying a coating material containing a ferromagnetic material to an arbitrary underlayer and solidifying or curing the coating.

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 described later 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 mass or less based on the solidified product of the paint.

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

  As described above, when the base 20 includes the ferromagnetic material, the magnet layer 14 of the second cosmetic material 10b is attracted to the base 20, and the second cosmetic material 10b can be fixed to the base 20. . Since the second cosmetic material 10b is detachable from the base 20, the base 20 is damaged when the second cosmetic 10b is dirty or damaged, or when it is desired to change the interior or exterior design. The second decorative material 10b can be easily replaced in a short period of time without giving Moreover, it is not necessary to use an adhesive when the second decorative material 10b is attached to the first decorative material 10a at the construction site. Therefore, no odor due to an organic solvent or the like is generated during drying. Furthermore, since the second decorative material 10b can be quickly and easily fixed to the first decorative material 10a, the construction period can be shortened.

  As shown in FIG. 3, each of the first underlayer 22 and the second underlayer 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.

  At least the second decorative material 10b is fixed to the base 20 with a magnetic force. When the first decorative material 10 a includes the magnet layer 14, the first decorative material 10 a is also fixed to the base 20 with a magnetic force. A plurality of first decorative materials 10a may be spread on one wall surface. In addition, a plurality of second decorative materials 10b may be spread on one wall surface. If it does so, conveyance of the 2nd decorative material 10b to a construction place will become easy. When the second decorative material 10b has flexibility, it can be rolled and transported. When a plurality of second decorative materials 10b are arranged and fixed on the wall surface, a gap may be provided between the adjacent second decorative material 10b and the second decorative material 10b. Then, even when the second decorative material 10b expands and contracts due to moisture or the like, the second decorative material 10b is unlikely to bend. However, when the entire second decorative material 10b is made of a material that hardly expands or contracts, such as a resin, a gap is provided between the adjacent second decorative material 10b and the second decorative material 10b. It is not necessary.

  Returning to FIG. 2, the decorative material 10 will be described in detail 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 the decorative layer 12 includes a surface layer 120 and a core material layer 129 in the present embodiment. The decorative layer 12 is, for example, one or more selected from the group consisting of melamine resin, polyvinyl chloride, polyvinyl fluoride, polyvinylidene fluoride, polyester, polytetrafluoroethylene, polyolefin resin, and (meth) acrylic resin. Consists of resin.

  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 design 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. Moreover, the design may be given to the surface of the design 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 decorative material 10. The decorative layer 12 has a design property that causes an aesthetic appearance when viewed from the design 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 design surface 101 side.

  The surface layer 120 carries, for example, a resin (first resin layer 123) containing a melamine resin on the design surface 101 side which is a design surface, and a solid thermoplastic emulsion resin on the first 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 carrying a minute (second resin layer 124). The first surface 102 is the surface opposite to the design surface 101 of the decorative material 10. 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 1st resin layer 123 is a layer containing resin (A), and is a transparent layer located in the design surface 101 side of the printing base material 122. FIG. 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 drawing, the first resin layer 123 is exposed on the design 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 design 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, or a kiss coater. And a method of heating and drying at about 80 to 130 ° C. after coating using an apparatus such as 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 first 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 printing base material 122 is improved and the printing base material 122 can be further 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 first surface 102 side of the printing substrate 122 is not particularly limited, and the above-described method for supporting the resin (A) on the design surface 101 side of the printing substrate 122. It can be performed in the same way. 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 first 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.

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.
