(First Embodiment)
FIG. 1 is a diagram for explaining a method of constructing a decorative material according to the first embodiment. This figure shows a cross section of a wall constructed by the method of this embodiment. Further, 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 has a decorative layer 12 and a magnet member 14 provided on the side opposite to the design surface 101b of the second decorative material 10b with respect to the decorative layer 12. Further, a ferromagnet is contained in the base 20 or between the base 20 and the design surface 101a of the first decorative material 10a. Then, in the sticking step, the second decorative material 10b is stuck by using the magnetic force of the magnet member 14. 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, an elevator, or the like. The building to which the interior or exterior is constructed is not particularly limited, and examples thereof include buildings and houses. Further, the present construction method may be a method of applying a decorative material to the surface of a moving body, furniture, or the like.

In the present embodiment, the first decorative material 10a and the second decorative material 10b have a structure like the decorative material 10 described below, for example. However, the first decorative material 10a and the second decorative material 10b may have the same configuration or may have different configurations. The first decorative material 10a may not be provided with the magnet layer 14, and may not be provided with 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 an aesthetic appearance. FIG. 2 shows an example in which the magnet member 14 is a sheet-shaped magnet layer. Hereinafter, the magnet member 14 will be described as the magnet layer 14, but the magnet member 14 is not limited to the sheet shape and is in the form of a lump. You may. The decorative material 10 is configured so that patterns and designs such as wood grain can be visually recognized 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 the first decorative material 10a is dirty, scratched, or when the design is to be renewed, and it is easy in a short time. It is possible to renew the appearance of the structure. In addition, the burden of storing and disposing of the peeled first decorative material 10a is also reduced. Further, since the second decorative material 10b is attracted by a magnetic force, it can be easily replaced when the appearance of the structure is renewed.

From the viewpoint of increasing the suction force to the base 20, the magnet layer 14 is preferably provided on almost the entire surface when viewed from the direction perpendicular to the design surface 101 of the decorative material 10. Further, it is more preferable that the magnet layer 14 is uniformly provided on the surface of the decorative material 10 opposite to the design surface 101. By doing so, it is possible to prevent the decorative material 10 from floating or bending from the base 20. Further, even if the planar shape of the decorative material 10 is processed, the function of attaching and detaching the decorative material 10 to the base 20 can be ensured. The fact that the magnet layer 14 is provided on almost the entire surface of the decorative material 10 means that the magnet layer 14 is provided in a region of 90% or more when 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 for joining 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.

FIG. 3 is a perspective view of the wall on which the second decorative material 10b is applied, and a part 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 skeleton 30 is covered with the first decorative material 10a and the second decorative material 10b. In the examples of FIGS. 1 and 3, the base 20 has a plurality of base layers. The base layer is a layer located between the frame of the wall and the first decorative material 10a. Alternatively, the base layer is a layer fitted in the framework of the wall so as to be located inside the wall with respect to the first decorative material 10a. The base layer exerts functions such as structural reinforcement, heat insulation, moisture proofing, waterproofing, and fire resistance, alone or in collaboration with each other. In the examples 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 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 frame 30 of the building. 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.

In the construction method according to the present embodiment, the base 20 contains a ferromagnetic material. Then, the magnet is attracted to the base 20. Ferromagnets include, for example, 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 base layer 24 and the first base layer 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 second decorative material 10b 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 a ferromagnetic material is a ferromagnetic plate such as an iron plate. Further, the plate material containing a 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 ferromagnet and the ferromagnet may be mixed or laminated. The composite member can be obtained, for example, by mixing iron powder with resin particles, wood chips, or the like 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 total area of the substrate 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 ferromagnet.

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 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 materials constituting the other base layer.

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

Paints include ferromagnetic materials and binders. The ferromagnetic material is, for example, 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 evenly. 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 described later as the binder contained in the magnet layer 14.

Further, the paint 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 mass or less with respect to the solidified product of the paint.

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

As described above, since the base 20 contains the ferromagnet, the magnet layer 14 of the second decorative material 10b is attracted to the base 20, and the second decorative material 10b can be fixed to the base 20. .. Since the second decorative material 10b is removable from the base 20, the base 20 is damaged when the second decorative material 10b becomes dirty or damaged, or when the interior or exterior design is to be changed. The second decorative material 10b can be easily replaced in a short time without giving. Further, when the second decorative material 10b is attached to the first decorative material 10a at the construction site, it is not necessary to use an adhesive. Therefore, no odor due to an organic solvent or the like is generated during drying. Further, 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, 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 boundary of the plurality of plate materials in the first base layer 22 and the boundary 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 portion 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.

At least the second decorative material 10b is magnetically fixed to the base 20. When the first decorative material 10a includes the magnet layer 14, the first decorative material 10a is also fixed to the base 20 by a magnetic force. A plurality of first decorative materials 10a may be spread on one wall surface. Further, a plurality of second decorative materials 10b may be spread on one wall surface. Then, the second decorative material 10b can be easily transported to the construction site. When the second decorative material 10b has flexibility, it can be rolled into a roll and transported. Further, 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 materials 10b and the second decorative materials 10b. Then, even when the second decorative material 10b expands and contracts due to moisture or the like, the second decorative material 10b is less likely to bend or the like. However, when the entire second decorative material 10b is made of a material that does not easily expand or contract, such as a resin, a gap is provided between the adjacent second decorative material 10b and the second decorative material 10b. It doesn't have to be.

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 in the present embodiment, the decorative layer 12 includes a surface layer 120 and a core material layer 129. The decorative layer 12 is one or more selected from the group composed of, for example, a melamine-based 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. 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 design 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 design surface 101 of the decorative material 10 may be designed.

It is preferable that the decorative material 10 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 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 such as the printed portion 121, that is, the printed pattern can be visually recognized from the design surface 101 side.

The surface layer 120 supports, for example, a resin containing a melamine resin (first resin layer 123) on the design surface 101 side, which is the 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 that carries a component (second resin layer 124). The first surface 102 is a 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. Further, 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 to the decorative material 10. The printing unit 121 is ink supported 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 thereof may be impregnated into the printing substrate 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 design 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 enhanced. In the example of this figure, 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 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 for supporting the resin (A) on the design 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 can be used, for example, a spray device, a shower device, or a kiss coater. , A method of applying by using a device such as a comma coater and then heating and drying at about 80 to 130 ° C. and the like can be mentioned.

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 have an adverse effect. 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. This makes it possible to improve the impregnation property of the resin varnish into the base material.

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 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 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 particle means a particle having a different phase structure of an acrylic resin and a urethane resin in a single particle.

Since each of the urethane resin and the acrylic resin has a high adhesive strength with the core material layer 129, good adhesive strength with the core material layer 129 can be exhibited by using the 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 phase 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 60 to 90 nm. As a result, the impregnation property between the fibers of the printing base material 122 is improved, and the printing base material 122 can be further impregnated with the inside of the printing base material 122, 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 first surface 102 side of the printing substrate 122 is not particularly limited, and the above-mentioned method of supporting the resin (A) on the design surface 101 side of the printing substrate 122. It can be done in the same way as. 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 have an adverse effect. 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. This makes it possible to improve the impregnation property of the thermoplastic emulsion resin into the base material.

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, the fact that the printed base material 122 carries 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 is supported after molding of 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 configured to include, 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. This makes it possible to impart sufficient heat resistance and nonflammability 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, the thickness should be set within an allowable range in the design of the final product. It is preferable that the thickness is 350 μm or less.

The magnet layer 14 is fixed to the first 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 including 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.

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 including Y), particularly R (where R is at least one of the rare earth elements including Y). 1), TM (where TM is at least one of the transition metals) and B (boron)-containing alloys.

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 polyimides and aromatic polyesters, polyphenylene oxides, polyphenylene sulfides, polyethylenes, polypropylenes, polyolefins such as ethylene-vinyl acetate copolymers, modified polyolefins, polycarbonates, polymethylmethacrylates, polyethylene terephthalates, polybutylene terephthalates, etc. Examples thereof include polyester, polyether, polyether ether ketone, polyetherimide, polyacetal, 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 more of these can be mixed and 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, silicone-based pressure-sensitive adhesives, and the like.

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 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. May be.

The core material layer 129 may also serve as the adhesive layer 13, such as when the core material layer 129 is impregnated with an adhesive. Further, the decorative layer 12 may further have a protective layer. The protective layer can be provided so as to be exposed on the design 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 design surface 101 of the decorative material 10, the reflectance of light, and the like can be adjusted, and the designability 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 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.

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.
