Description

  The present invention relates to an interior seat, and a room and a vehicle using the interior seat.

Conventionally, a convection type air conditioner is generally used as a room temperature control system. However, in this convection type air conditioner, since the indoor temperature is controlled by heating or cooling the air, there is a problem that the temperature distribution difference in the vertical direction in the room tends to be large and the energy loss is large. In addition, there is a problem that the convection of the air conditioner directly touches the skin, and pollen, dust, etc. are scattered and dispersed in the room.
Therefore, there has been proposed a floor heating device, a radiant cooling and heating device, and the like, which utilize far infrared radiation with high indoor temperature uniformity and high heating and cooling efficiency. As a method of effectively utilizing such heat radiation, for example, a constituent member such as a wall surface or a floor surface in a room is made of a material containing a substance having an emissivity of far infrared rays of 0.6 or more, and cold radiation or heat radiation is performed. An indoor environment adjustment system including a heat source has been proposed (see, for example, Patent Document 1).

When the infrared rays emissivity of the components such as the wall surface and floor surface in the room is high, for example, in summer, the solar heat entering through the window is absorbed preferentially. Even if it does, since the high radiation surface such as the wall surface is first cooled, there arises a problem that the cooling of the indoor space is delayed and the energy efficiency is deteriorated. In winter, heat radiation from a person is absorbed by a cold wall surface, which may cause a problem of feeling cold.
In order to solve such a problem, a member having a high infrared reflectance (infrared reflecting member) may be used as the interior member. As the infrared reflecting member, a heat shield sheet in which a metal layer and a heat shield coating layer are arranged on a porous layer (see, for example, Patent Document 2), a transparent metal layer and an anchor coat layer on the surface of a base film, an organic layer A transparent reflective sheet having a resin layer (for example, see Patent Document 3) has been proposed.

However, in the heat-shielding sheet of Patent Document 2, since the heat-shielding paint layer has a very large thickness of about 100 μm, the workability of the infrared reflecting member is poor, and it may be difficult to give a design such as a pattern.
Since the reflecting member of Patent Document 3 is transparent and has no design layer such as a pattern, it is difficult to apply the reflecting member as an interior member. Further, even if a design layer such as a pattern is added to the reflecting member by printing or the like, infrared rays may be absorbed in the design layer formed of a pigment that is generally used, and the infrared ray reflecting member sufficiently absorbs infrared rays. May not be able to reflect.

The left-right direction is the Y direction. In the vertical direction, the vertical upper side is the + Z side, the vertical lower side is the -Z side, the back side in the depth direction is the -X side, and the front side is the + X side.

  As shown in FIG. 1, the room 1 is a building room in which an opening is provided on the back side (−X side), and a window 2 is arranged in the opening. An interior member is provided on the indoor side of the room 1, and the interior member includes a wall member 10 that surrounds the horizontal direction (X direction, Y direction) of the room, and a ceiling member 10 ′ that covers the ceiling side of the room. , And a floor member 30 that covers the floor side of the room.

(Wall member 10)
FIG. 2 is a diagram illustrating details of the wall member 10 of the present embodiment. FIG. 2 shows a cross-sectional shape parallel to the thickness direction of the wall member 10.
The wall member 10 is an interior member that covers the wall on the indoor side of the room 1. As shown in FIG. 2, the wall member 10 includes a base member 11, an adhesive layer 12, and an interior sheet 20, which are sequentially stacked. The wall member 10 is arranged in the room 1 so that the surface on the interior seat 20 side is the interior side, and the design layer 24 (described later) provided on the interior seat 20 is visually recognized from the interior side. be able to.
The base member 11 is a member that is a base of the wall member 10, and a gypsum board is used in the present embodiment.
The adhesive layer 12 is a layer composed of an adhesive that adheres the interior sheet 20 to the base member 11. For the adhesive layer 12, for example, a starch-based adhesive or a starch paste-based adhesive can be used.

The interior sheet 20 is a sheet-shaped member that is attached to the interior side of the base member 11 and has a design such as a picture or letters. As shown in FIG. 2, the interior sheet 20 has a backing sheet 21, a base material layer 22, an infrared reflection layer 23, a design layer 24, and a surface protection layer 25 laminated in this order from the side of the base member 11 (outdoor side). There is.
As described above, the interior sheet 20 is provided with the infrared reflection layer 23 and has a function of reflecting the infrared rays incident from the indoor side, and the wall member 10 absorbs the indoor heat. It can be suppressed as much as possible.

  If a wall member having a high emissivity of infrared rays is used indoors, such as an infrared absorbing member that absorbs infrared rays, for example, in the summer, the wall member absorbs heat of sunlight incident from outside. Therefore, even if an attempt is made to cool the inside of the room by the cooling device, the high radiation surface of the wall member is first cooled, and the cooling of the indoor space is delayed. Further, in winter, the heat of the heating device is absorbed by the wall member, which slows the heating of the indoor space.

On the other hand, in the wall member 10 of the present embodiment, as described above, the interior sheet 20 is provided with the infrared reflective layer 23, so that the heat of the cooling device and the heating device (hereinafter referred to as the cooling and heating device) is not generated. It is possible to prevent the wall member 10 from being absorbed. Further, for example, even if sunlight is incident from the outside through the window in the summer, it is possible to prevent the wall member 10 from absorbing heat. Therefore, when it is attempted to cool or heat the room by the air conditioner, the room space of the room 1 can be cooled or heated more quickly, and the room can be made into a comfortable temperature environment.
In addition, as the cooling and heating apparatus arranged in the room 1 of the present embodiment, it is desirable to apply a radiant cooling and heating apparatus rather than a convection cooling and heating apparatus. In the case of the radiant cooling and heating device, the radiated heat can be reflected to the indoor side by the interior sheet 20 having the infrared reflection layer 23, and the temperature of the indoor space of the room 1 can be adjusted more efficiently and uniformly. Is.

The backing sheet 21 is an easy-adhesion member that facilitates adhesion between the interior sheet 20 and the adhesive layer 12. As the backing sheet 21 of this embodiment, a known fibrous sheet (backing paper) or the like can be used. Specifically, general paper for wallpaper (pulp-based sheet treated with a known sizing agent) or flame-retardant paper (pulp-based sheet treated with a flame retardant such as guanidine sulfamate or guanidine phosphate). Materials), inorganic paper containing inorganic additives such as aluminum hydroxide and magnesium hydroxide, fine paper, thin paper, and the like. Backing sheet 21 is the basis weight of the substrate is not critical, preferably about 50 to 300 g / ^{m 2,} more preferably about 50 to 120 / ^{m 2,} provided in the outdoor side surface of the base layer 22 ing.
The base material layer 22 is a base member of the interior sheet 20, and is formed of, for example, an olefin resin or a vinyl chloride resin. The base material layer 22 of the present embodiment contains the foaming agent in the resin material, and in the process of forming the base material layer 22, the resin is softened by heating and gas is generated from the foaming agent to generate the base material layer 22. Is inflated to a predetermined thickness.

Therefore, the base material layer 22 is formed in a porous shape having a large number of bubbles inside. Here, examples of the foaming agent contained in the resin forming the base material layer 22 include at least one selected from the group consisting of azo compounds, ammonium carbonate, ammonium bicarbonate and ammonium nitrite. Among these, as the azo compound, azodicarbonamide (ADCA), azobisformamide and the like can be used. The ratio of the content of the foaming agent with respect to the resin forming the base material layer 22 is preferably about 1 to 20 parts by mass with respect to 100 parts by mass of the resin component.
The base material layer 22 is formed in a thickness range of 300 to 700 μm in a state of being laminated with the backing sheet 21 described above from the viewpoint of facilitating the handling of the interior sheet 20 in the field and the winding property during production. It is desirable to be done.
Further, the base material layer 22 contains calcium carbonate or titanium oxide, and contains an inorganic filler such as aluminum hydroxide, magnesium hydroxide, antimony trioxide, zinc borate, or molybdenum compound. By including the filler, the effect of suppressing seepage and the effect of improving surface characteristics can be obtained.

Here, since the infrared reflection layer 23 provided on the indoor side of the base material layer 22 has an infrared reflectance of 20% or more as described later, a part of the infrared rays incident on the infrared reflection layer 23 is reflected by the infrared rays. It is not reflected by the layer 23 and is transmitted to the base material layer 22 side. As described above, when the base material layer 22 is formed in a white color, a silver color, or a color close to these colors, a part of infrared light that is transmitted without being reflected in the infrared reflective layer 23 is The material layer 22 can be reflected to the indoor side, and the reflection efficiency of infrared rays in the interior sheet 20 can be improved. In addition, the color of the design applied to the design layer 24 provided on the indoor side of the base material layer 22 can be visually recognized more clearly.
The ratio of the content of calcium carbonate or titanium oxide to the resin forming the base material layer 22 is such that the content of the inorganic filler is 0 with respect to 100 parts by mass of the resin component from the viewpoint of sufficiently reflecting the incident infrared rays. Is preferably about 100 to 100 parts by mass, more preferably about 20 to 70 parts by mass.

The infrared reflection layer 23 is a layer that is provided on the surface of the base material layer 22 on the indoor side and reflects infrared rays incident from the indoor side. The infrared reflective layer 23 is configured in any of the following three forms (infrared reflective layer 23A, infrared reflective layer 23B, infrared reflective layer 23C).
The infrared reflective layer 23A is formed by forming an aluminum thin film having a good infrared reflective property with a thickness of 50 nm to 10 μm. The infrared reflection layer 23A is formed in a silver color (metal color) when viewed from the outside, and its infrared ray (780 nm to 2500 nm) reflectance is 80% or more. The infrared reflective layer 23A can be formed by, for example, a vacuum vapor deposition method or the like in which vapor-deposited metal (aluminum) is evaporated and adhered to the inner surface of the base material layer 22.

Further, the infrared reflection layer 23A may be formed by forming a thin film of aluminum having through holes formed at predetermined intervals to the above thickness. It is desirable that the through-holes have holes of uniform size arranged at equal intervals from the viewpoint that infrared rays are reflected uniformly by the portions other than the holes of the aluminum thin film. As described above, since the infrared reflection property of the aluminum thin film is as good as 80% or more, even if the through hole is provided in the aluminum thin film, it is possible to realize the infrared light reflectance of 80% or more. it can.
As the aluminum thin film having a through hole, other than the above-described method by vapor deposition, for example, a sheet of aluminum having a through hole is used, or by pattern printing with an ink containing aluminum fine particles (powder), Can be made. From the viewpoint of obtaining sufficient reflection characteristics, the thickness of the aluminum thin film is preferably 6 μm or more when an aluminum sheet is used, 0.5 μm or more when formed by pattern printing, and 50 nm or more when formed by vapor deposition. Is desirable. In the case of forming a thin aluminum film by vapor deposition, the upper limit of the thickness is preferably 100 nm from the viewpoint of suppressing a decrease in adhesiveness and a decrease in productivity due to a thick film.

The infrared reflective layer 23B is a layer formed of ATO (antimony tin oxide), ITO (indium tin oxide), Ag alloy, or the like and having a thickness of 5 to 10 nm. The infrared reflection layer 23B is formed so that the color viewed from the outside is transparent or substantially transparent, and the reflectance of infrared rays (780 nm to 2500 nm) is 20% or more. Here, “substantially transparent” means a state in which the layer (infrared reflecting layer 23B) is seen from one surface side and the other side can be seen through.
The infrared reflective layer 23B can be formed by a vacuum film forming method such as sputtering.

  The infrared reflective layer 23C is a layer formed of a resin containing a pigment having an infrared reflective property and having a thickness of 2 to 10 μm. The infrared reflective layer 23C can be formed so that the tint thereof is different depending on how to disperse the contained pigment having infrared reflective properties. Therefore, the infrared reflection layer 23C can be used also as a design layer by adjusting the dispersion state of the pigment to form a design such as a picture or a character. The reflectance of infrared rays (780 nm to 2500 nm) of the infrared reflective layer 23C is 40% or more.

  The infrared reflective layer 23C can be formed by applying or printing a resin in which a pigment having an infrared reflective property is dispersed. In addition, as the pigment having infrared ray reflection characteristics used for the infrared reflection layer 23C, titanium oxide, aluminum, a complex oxide of calcium element, titanium element, manganese element, iron-chromium, bismuth-cobalt, or the like pigment. Can be used. The base material (resin containing the above pigment) of the infrared reflective layer 23C includes urethane resin, acrylic resin, acrylic urethane resin, vinyl chloride / vinyl acetate copolymer resin, vinyl chloride / vinyl acetate / acrylic copolymer. Resin, chlorinated polypropylene resin, polyester resin, polyamide resin, butyral resin, polystyrene resin, nitrocellulose resin (nitrified cotton), cellulose acetate resin, etc. are used alone or in combination of two or more. Things can be used. The ratio of the content of the pigment such as titanium oxide to the resin as the base material is preferably 75% by mass or less based on the solid content, more preferably 30 to 75% by mass, and further preferably 50 to 75% by mass. .

The infrared reflection layer 23 can be appropriately selected from the infrared reflection layers 23A to 23C according to the specifications of the infrared reflection function of the interior sheet 20 and the like.
In addition, since the infrared reflective layer 23A has a reflectance of 80% or more not only for near infrared rays but also for mid infrared rays and far infrared rays, it is necessary to reflect mid infrared rays and far infrared rays having a longer wavelength than near infrared rays. It is especially effective in some cases.

The design layer 24 is a layer provided on the surface of the infrared reflection layer 23 on the indoor side and provided with a design such as a design or characters (for example, a design of wood grain). The design applied to the design layer 24 can be visually recognized through the surface protection layer 25 when the interior sheet 20 is viewed from the indoor side.
The design layer 24 of the present embodiment has a function of transmitting infrared rays, transmits infrared rays incident from the indoor side to the infrared reflecting layer 23, and transmits infrared rays reflected by the infrared reflecting layer 23 to the indoor side. be able to.

The design layer 24 that transmits infrared rays includes, for example, at least one kind of pigment (hereinafter referred to as infrared transmission pigment) selected from isocindrinone, disazo, polyazo, dikepyrrolopyrrole, quinacridone, phthalocyanine, and titanium oxide. It is formed by applying or printing the contained resin on the infrared reflecting layer 23 described above.
In addition, as the resin that is the base material of the design layer 24, urethane resin, acrylic resin, acrylic urethane resin, vinyl chloride / vinyl acetate copolymer resin, vinyl chloride / vinyl acetate / acrylic copolymer resin, chlorinated polypropylene resin , Polyester resin, polyamide resin, butyral resin, polystyrene resin, nitrocellulose resin (nitrified cotton), cellulose acetate resin, etc. may be used alone or in combination of two or more. it can.
The design layer 24 may be provided in a plurality of layers depending on the design to be applied. The layer thickness of the design layer 24 is preferably 1 μm or more from the viewpoint of obtaining sufficient hiding property and designability, and is 10 μm or less from the viewpoint of obtaining sufficient adhesion regardless of whether it is a single layer or a plurality of layers. desirable.

The surface protection layer 25 is a layer that is located on the most indoor side of the interior seat 20 and transmits transparent infrared rays, and is provided to protect the interior surface of the interior seat 20. The surface protective layer 25 has an acrylic urethane resin, a polyester resin, a phenol resin, an epoxy resin, a polyurethane resin, an aminoalkyd resin, a melamine resin, a guanamine resin, in order to have scratch resistance for suppressing scratches due to rubbing or the like. A thermosetting resin or a thermoplastic resin such as a urea resin, an acrylic resin, a vinyl acetate resin, a styrene resin can be used. Among these thermosetting resins and thermoplastic resins, acrylic resins and polyurethane resins are preferable. The dry-curable resin may be used alone or in combination of two or more.
The thickness of the surface protective layer 25 is formed in the range of 1 to 10 μm. If the thickness of the surface protective layer 25 is less than 1 μm, the thickness of the surface protective layer 25 becomes too thin, and the scratch resistance decreases, which is not desirable. Further, when the thickness of the surface protective layer 25 is larger than 10 μm, productivity is reduced, which is not desirable.
As described above, the interior sheet 20 makes it possible to visually recognize the design applied to the design layer from the indoor side and efficiently reflect the incident infrared rays to the indoor side. Thereby, the heat absorption of the wall member 10 can be suppressed as much as possible, the temperature of the indoor space of the room 1 can be adjusted more quickly, and the room can be made into a comfortable temperature environment.

(Method for manufacturing interior sheet 20)
Next, an example of a method for manufacturing the interior seat 20 will be described.
First, the backing sheet 21 is prepared, and the foaming agent-containing resin layer is extruded on one surface of the backing sheet 21 to form a film. When the non-foamed resin layer is provided on one side or both sides, simultaneous extrusion film formation by a T die extruder is suitable. For example, when a non-foamed resin layer is provided on both surfaces, a multi-manifold type T die capable of simultaneously forming three layers by extruding molten resin corresponding to the three layers can be used. Here, the T-die means a die for extruding a molding resin formed in a form in which two dies each having a T-shaped groove formed on one side thereof are overlapped with the T-shaped grooves facing each other.
In the case where the resin composition forming the foaming agent-containing resin layer contains an inorganic filler and the foaming agent-containing resin layer is formed by extrusion film formation, an extrusion port of an extruder (so-called die) Inorganic filler residues (so-called eyes) tend to occur, which easily becomes foreign matter on the surface of the foaming agent-containing resin layer. Therefore, when the resin composition forming the foaming agent-containing resin layer contains an inorganic filler, it is preferable to perform the three-layer coextrusion film formation as described above. That is, the coextrusion of the foaming agent-containing resin layer sandwiched by the non-foaming resin layers to form a film makes it possible to suppress the occurrence of the eye blemishes.
After forming the foaming agent-containing resin layer, electron beam irradiation may be performed. This makes it possible to crosslink the resin component and adjust the surface strength, foaming characteristics and the like of the foamed resin layer. The electron beam energy is preferably about 150 to 250 kV, more preferably about 175 to 200 kV. The irradiation dose is preferably about 10 to 100 kGy, more preferably about 10 to 50 kGy. A known electron beam irradiation device can be used as the electron beam source. As described above, the base material layer 22 before foaming is formed on one surface of the backing sheet 21.

Then, the infrared reflection layer 23 is formed on the surface of the base material layer 22 on the indoor side (the side opposite to the backing sheet 21). For example, when the infrared reflective layer is the infrared reflective layer 23A, the vapor deposition metal (aluminum) is heated and melted and evaporated in a vacuum environment by a vacuum vapor deposition method, and the vaporized vapor deposition metal is placed inside the base material layer 22. The infrared reflection layer 23A is formed by colliding and adhering to the surface.
Next, a resin containing an infrared transmitting pigment is applied (printed) to the surface of the infrared reflecting layer 23 on the indoor side (the side opposite to the base material layer 22) to cure the resin, thereby having an infrared transmitting function. The design layer 24 is formed.
Subsequently, a urethane acrylic resin is applied (printed) to the surface of the design layer 24 on the indoor side (the side opposite to the infrared reflection layer 23) and cured to form the surface protection layer 25.
Next, the foaming resin layer (porous base material layer 22) is formed by heating the foaming agent-containing resin layer. The heating conditions are not limited as long as the foamed resin layer is formed by the decomposition of the thermal decomposition type foaming agent. The heating temperature is preferably about 210 to 240 ° C., and the heating time is preferably about 20 to 80 seconds.
Finally, a laminated body in which the base material layer 22, the infrared reflection layer 23, the design layer 24, and the surface protection layer 25 are laminated in this order on the backing sheet 21 is passed between a cooling roll and a pressure roll, if necessary. By thermocompression bonding while embossing, the interior sheet 20 having an uneven pattern on the surface is completed.

Next, another form of the interior seat 20 used for the wall member 10 will be described.
FIG. 3 shows another form of the interior seat 20. Each drawing in FIG. 3 shows a cross-sectional shape in a cross section parallel to the thickness direction of the interior seat.
In the above description, as shown in FIG. 2, the interior sheet 20 has a backing sheet 21, a base material layer 22, an infrared reflection layer 23, a design layer 24, and a surface protection layer 25 laminated in this order from the outdoor side. However, the present invention is not limited to this.

(Another Form 1 of Interior Seat 20)
For example, as shown in FIG. 3A, the interior sheet 20 includes a backing sheet 21, a base material layer 22, an infrared reflection layer 23, a transparent base material layer (infrared transmission layer) 26, and a design layer in order from the outdoor side. 24 'and the surface protection layer 25 may be laminated. Here, the backing sheet 21, the base material layer 22, the infrared reflection layer 23, and the surface protection layer 25 are the backing sheet 21, the base material layer 22, the infrared reflection layer 23, and the surface protection layer 25 of the form shown in FIG. Is the same as.
The transparent base material layer 26 is a transparent resin sheet provided between the infrared reflection layer 23 and the design layer 24 'and capable of transmitting infrared rays, and is made of, for example, PET (polyethylene terephthalate) resin, polyethylene resin, polypropylene resin, or the like. Has been formed. The transparent base material layer 26 is preferably formed with a thickness dimension of 80 μm or less from the viewpoint of efficiently transmitting infrared rays incident from the indoor side to the infrared reflective layer 23 side. If it is larger than 80 μm, the amount of infrared rays incident on the transparent base material layer 26 decreases, which is not desirable.

  The design layer 24 ′ is a layer on which a design such as a design or letters (for example, a design of wood grain or stone tone) is applied, like the design layer 24 of the form shown in FIG. 2 described above. Unlike the design layer 24, the design layer 24 'does not need to have a function of transmitting infrared rays, and may have a function of absorbing infrared rays. Therefore, a material having a function of absorbing light such as carbon black can be used. By applying this carbon black to the design layer 24 ′, the blackness contained in the color applied to the design can be made clearer than that of the design layer 24 described above.

  Even if the infrared rays incident from the indoor side are absorbed by the design layer 24 ′, the transparent base material layer 26 is provided between the design layer 24 ′ and the infrared reflection layer 23, so that the absorbed infrared rays A part of the light can be emitted from the interface between the design layer 24 ′ and the transparent base material layer 26 toward the infrared reflection layer 23 side. The light emitted from the design layer 24 ′ passes through the transparent base material layer 26, is reflected by the infrared reflecting layer 23, passes through the transparent base material layer 26 again, and is absorbed by the design layer 24 ′, and a part thereof Will be emitted from the interface with the surface protective layer 25 to the indoor side. Therefore, the interior sheet 20 of the present embodiment can also suppress the heat generated by infrared rays from being accumulated in the wall member 10.

Examples of pigments that can be used in the design layer 24 ′ include inorganic pigments such as titanium oxide, zinc white, carbon black, black iron oxide, yellow iron oxide, yellow lead, molybdate orange, in addition to the above infrared transmitting pigments. Examples thereof include cadmium yellow, nickel titanium yellow, chrome titanium yellow, iron oxide (valve), cadmium red, ultramarine blue, dark blue, cobalt blue, chromium oxide, cobalt green, aluminum powder, bronze powder, titanium mica, and zinc sulfide. Examples of organic pigments include aniline black, perylene black, azo (azo lake, insoluble azo, condensed azo), polycyclic (isoindolinone, isoindoline, quinophthalone, perinone, flavantron, anthrapyrimidine, anthraquinone, quinacridone. , Perylene, diketopyrrolopyrrole, dibromoanthanthrone, dioxazine, thioindigo, phthalocyanine, indanthrone, halogenated phthalocyanine) and the like, which are commonly used in printing, etc., can be appropriately used. The design layer 24 ′ is formed with a thickness of 10 μm or less from the viewpoint of ensuring adhesiveness.
As described above, the design layer 24 ′ does not need to have an infrared ray transmitting function unlike the design layer 24 shown in FIG. 2 described above, and a pigment or the like that absorbs infrared rays can be used. The above types of materials can be applied to the formation of the design layer 24 ', and the variation of the tint applied to the design such as a design or a character can be increased.
Even if the interior sheet 20 has such a form, the same effect as that of the form shown in FIG. 2 can be obtained, that is, the design of the design layer can be visually recognized from the indoor side and the incident infrared rays can be efficiently reflected. it can. As a result, the temperature of the indoor space of the room 1 can be adjusted more quickly, and the room can have a comfortable temperature environment.

(Another Form 2 of Interior Seat 20)
In addition, as shown in FIG. 3B, the interior sheet 20 includes a backing sheet 21, a base material layer 22, an infrared reflection layer 23, an air layer 27, a design sheet 28, and a surface protection layer 25 in this order from the outdoor side. It may be laminated. Here, the backing sheet 21, the base material layer 22, the infrared reflection layer 23, and the surface protection layer 25 are the backing sheet 21, the base material layer 22, the infrared reflection layer 23, and the surface protection layer 25 of the form shown in FIG. Is the same as.

The air layer 27 is a layer in which an air layer provided between the infrared reflection layer 23 and the design sheet 28 is interposed. The air layer 27 of the present embodiment is formed in a net shape along the surface of the infrared reflection layer 23 on the indoor side, and an air layer is formed in each stitch. The air layer 27 is formed by pasting a net-like resin sheet on the infrared reflecting layer 23, or printing a resin (ink) on the infrared reflecting layer 23 in a net-like pattern.
This air layer 27, like the transparent base material layer 26 provided in the other form 1 shown in FIG. 3 (a), partially absorbs the infrared rays absorbed in the design sheet 28 to the infrared reflection layer 23 side. It is provided for emitting light.
The coverage of the air layer 27 (the ratio of the area of the infrared reflective layer 23 to the area covered by the mesh air layer 27) is such that the infrared rays emitted from the design sheet 28 are efficiently incident on the infrared reflective layer 23. Therefore, it is preferably less than 50%.
The net-like shape of the air layer 27 is made of urethane resin, acrylic resin, acrylic urethane resin, vinyl chloride / vinyl acetate copolymer resin, vinyl chloride / vinyl acetate / acrylic copolymer resin, chlorinated polypropylene resin, polyester resin, polyamide. Any one selected from resins, butyral resins, polystyrene resins, nitrocellulose resins (nitrified cotton), cellulose acetate resins and the like is formed by using one kind alone or a mixture of two or more kinds. The thickness of the air layer 27 is formed within the range of 1 to 20 μm.

The design sheet 28 is a sheet-shaped resin member on which a design such as a pattern or a character is applied, and the design sheet 28 has another form 1 of the interior sheet 20 shown in FIG. The design layer 24 'is formed. The design sheet 28 is formed into a sheet-shaped member because it is difficult to form the design layer with a uniform thickness on the air layer 27 having an air layer. Therefore, the interior sheet 20 of the present embodiment is formed by attaching the design sheet 28 manufactured in a separate process to the surface of the air layer 27 opposite to the infrared reflection layer 23.
The design sheet 28 does not need to be a design layer having an infrared ray transmitting function and has a function of absorbing infrared rays, like the design layer 24 ′ of the other form 1 shown in FIG. 3A described above. May be. Thereby, even if infrared rays are absorbed by the design sheet 28, since the air layer 27 is provided on the outdoor side of the design sheet 28 (the surface on the infrared reflection layer 23 side), part of the absorbed infrared rays is The infrared ray can be emitted from the interface with the air layer 27 toward the infrared reflective layer 23 side. Therefore, the interior seat 20 of the present embodiment can also prevent the heat generated by infrared rays from being accumulated in the wall member 10.

The resin film forming the design sheet 28 is, for example, urethane resin, acrylic resin, acrylic urethane resin, vinyl chloride / vinyl acetate copolymer resin, vinyl chloride / vinyl acetate / acrylic copolymer resin, chlorinated polypropylene resin, polyester. The resin, the polyamide resin, the butyral resin, the polystyrene resin, the nitrocellulose resin (nitrified cotton), the cellulose acetate resin, etc. are formed by using any one kind alone or as a mixture of two or more kinds. A sheet-shaped substrate having a thickness of 1 to 10 μm can be used.
Further, the design layer 24 ′ forming the design sheet 28 is formed of the same material and size as the design layer 24 ′ of the different form 1 of the interior sheet 20 shown in FIG. 3 (a).
In the case where the resin film constituting the design sheet 28 is colored in a dark color such as black, from the viewpoint of preventing the design applied to the design layer 24 ′ from being invisible from the indoor side, the resin The film is preferably placed on the outdoor surface of the design layer 24 '. In the case where the resin film is transparent or substantially transparent, and the back side is transparent such as white, it may be arranged on any of the indoor surface of the design layer 24 ′ and the outdoor surface of the design layer 24 ′. Good.

As described above, the design sheet 28 does not need to have an infrared ray transmitting function unlike the design layer 24 shown in FIG. 2 described above, and a member that absorbs infrared rays can also be used, so that more types can be used. It is possible to use the materials and inks described above for forming the design sheet 28, and it is possible to increase the variation in color tint applied to designs such as pictures and letters.
Even if the interior sheet 20 has such a form, the same effect as that of the form shown in FIG. 2 can be obtained, that is, the design of the design layer can be visually recognized from the indoor side and the incident infrared rays can be efficiently reflected. it can. As a result, the temperature of the indoor space of the room 1 can be adjusted more quickly, and the room can have a comfortable temperature environment.

As a result, the temperature of the indoor space of the room 1 can be adjusted more quickly, and the room can have a comfortable temperature environment.
Further, unlike the design layer 24 shown in FIG. 2 described above, it is not necessary to provide the design layer 24 ′ with a function of transmitting infrared rays, and since a member that absorbs infrared rays can be used, more types of materials can be used. The (pigment) can be used for forming the design layer 24 ', and the variation of the tint applied to the design such as a design or a character can be increased.

Even if the floor member has a surface protective layer, it penetrates the surface protective layer and is present in the lower layer. There is a possibility that the design layer, the infrared reflection layer, etc. may be damaged. Therefore, the floor member 30 of the present embodiment is provided with the intermediate layer 45 in order to prevent the design layer 44 and the infrared reflection layer 43, which are lower layers than the surface protection layer 46, from being scratched or the like. .
The intermediate layer 45 is made of PP (polypropylene) resin, olefin resin, or the like, and the layer thickness thereof is in the range of 40 to 100 μm.

In the above description, as shown in FIG. 4, in the interior sheet 40, the base material layer 42, the infrared reflection layer 43, the design layer 44, the intermediate layer 45, and the surface protection layer 46 are arranged in this order from the underfloor side (outdoor side). Although the stacked form has been described, the present invention is not limited to this.

Is the same as.
The transparent base material layer 47 is a transparent resin sheet which is provided between the infrared reflective layer 43 and the design layer 44 ′ and is capable of transmitting infrared rays. The transparent base material layer 47 is formed of the same material and size as the transparent base material layer 26 of the different form 1 (see FIG. 3A) of the interior sheet 20 provided on the wall member 10 described above. .

The design layer 44 ′ is a layer on which a design such as a design or a character (for example, a design of wood grain) is applied similarly to the design layer 44 having the form shown in FIG. 4 described above. Unlike the design layer 44, the design layer 44 'does not need to have a function of transmitting infrared rays, and may have a function of absorbing infrared rays. The design layer 44 ′ has the same form as the design layer 24 ′ of another form 1 of the interior sheet 20 provided on the wall member 10 described above, and is formed of the same material and size as the design layer 24 ′. There is.
As described above, the interior sheet 40 of the present embodiment is provided between the design layer 44 ′ and the infrared reflection layer 43 even if the infrared rays incident from the floor upper side (inside the room) are absorbed by the design layer 44 ′. The transparent base material layer 47 allows a part of the infrared rays absorbed to be emitted to the infrared reflective layer 43 from the interface between the design layer 44 ′ and the transparent base material layer 47. The light emitted from the design layer 44 ′ passes through the transparent base material layer 47, is reflected by the infrared reflecting layer 43, passes through the transparent base material layer 47 again, and is absorbed by the design layer 44 ′. Will be emitted from the interface with the surface protective layer 46 to the indoor side. Therefore, the interior sheet 40 of the present embodiment can also suppress the heat generated by infrared rays from being accumulated in the floor member 30.

Can be reflected. As a result, the temperature of the indoor space of the room 1 can be adjusted more quickly, and the room can have a comfortable temperature environment.
Further, since the design layer 44 'is not limited to the infrared transmissive pigment like the design layer 44 of the floor member 30 in the form shown in FIG. 4 described above, more kinds of materials are applied to the formation of the design layer 44'. Therefore, it is possible to increase the variation of color tint applied to designs such as pictures and letters.

In addition, as shown in FIG. 5B, the interior sheet 40 includes a base material layer 42, an infrared reflective layer 43, an air layer 48, a design sheet 49, an intermediate layer 45, and a surface in this order from the underfloor side (outdoor side). The protective layer 46 may be laminated. Here, the base material layer 42, the infrared reflective layer 43, the intermediate layer 45, and the surface protective layer 46 are the base material layer 42, the infrared reflective layer 43, the intermediate layer 45, and the surface protective layer 46 of the form shown in FIG. 4, respectively.

The design sheet 49 is a sheet-shaped resin member on which a design such as a design or a character is applied. The design sheet 49 is formed as a sheet-shaped member because it is difficult to form the design layer with a uniform thickness on the air layer 48 having an air layer.
The design sheet 49 is a sheet-shaped resin member on which a design such as a picture or a character is applied, and the design sheet 49 has another form 1 of the interior sheet 40 shown in FIG. The design layer 44 'is formed. The resin film and the design layer 44 ′ forming the design sheet 49 are the same as the resin film and the design layer 24 ′ forming the design sheet 28 of another mode 2 of the interior sheet 20 provided on the wall member 10 described above. It is formed by the material, size, and so on.
As a result, even if infrared rays are absorbed by the design sheet 49, the air layer 48 is provided on the surface of the design sheet 49 on the underfloor side (outside the room, on the infrared reflection layer 43 side). Can be emitted to the infrared reflection layer 43 from the interface with the air layer 48. Therefore, the interior sheet 40 of the present embodiment can also suppress the heat generated by infrared rays from being accumulated in the floor member 30.

Can be reflected. As a result, the temperature of the indoor space of the room 1 can be adjusted more quickly, and the room can have a comfortable temperature environment.
Further, the design sheet 49 is not limited to the infrared transmissive pigment like the design layer 44 of the floor member 30 of the form shown in FIG. 4 described above, so that more kinds of materials should be applied to the formation of the design sheet 49. Therefore, it is possible to increase the variation of color tint applied to designs such as patterns and letters.

(Another Form 3 of Interior Seat 40)
In addition, as shown in FIG. 5C, the interior sheet 40 has a base material layer 42, a design layer 44 ′, an infrared reflection layer 43 B, an intermediate layer 45, and a surface protection layer 46 in this order from the floor underside (outdoor side).

Here, the base material layer 42, the intermediate layer 45, and the surface protective layer 46 are the same as the base material layer 42, the intermediate layer 45, and the surface protective layer 46 of the form shown in FIG. 4, respectively.

The design layer 44 ′ of this embodiment is the same as the design layer 44 ′ of another embodiment 1 of the interior sheet 40 shown in FIG. 5 (a) described above.
Since the infrared reflection layer 43 of the present embodiment is formed on the floor upper side (inside the room) of the design layer 44 ′, the design provided on the design layer 44 ′ is visible from the floor upper side (inside the room). The infrared reflecting layer formed transparently or substantially transparently, that is, the infrared reflecting layer 43B of the above-mentioned three types of infrared reflecting layers is used.

Can be reflected. As a result, the temperature of the indoor space of the room 1 can be adjusted more quickly, and the room can have a comfortable temperature environment.
Further, unlike the design layer 44 shown in FIG. 4 described above, it is not necessary to provide the design layer 44 ′ with a function of transmitting infrared rays, and a member that absorbs infrared rays can be used, so that more types of materials can be used. The (pigment) can be used for forming the design layer 44 ', and the variation of the tint applied to the design such as a design or a character can be increased.

(Another Form 4 of Interior Seat 40)
Further, in the interior sheet 40, as shown in FIG. 5D, a base layer 42, an infrared reflection layer 43C, an intermediate layer 45, and a surface protection layer 46 are laminated in this order from the underfloor side (outdoor side).

For example, in the summer, the room 1 with the windows 2 completely closed retains hot air, but since the wall member 10, the ceiling member 10 ′, and the floor member 30 hardly absorb the heat, the indoor space is once ventilated. The hot air can be exhausted and the indoor space can be quickly cooled by the subsequent use of the cooling device. Further, in the winter, when the heating device is used to heat the cold indoor space, the heat of the heating device is hardly absorbed by the wall member 10, the ceiling member 10 ′, and the floor member 40. It can warm the indoor space.
In addition, by using the radiant cooling and heating device for controlling the temperature of the room 1, the heat emitted from the cooling and heating device is reflected by the infrared reflection layer provided on the interior sheet, and the indoor space is cooled more efficiently and uniformly. It can be heated or warmed.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made as in the modifications described later, which are also included in the present invention. It is within the technical scope. In addition, the effects described in the embodiments are merely enumeration of the most suitable effects generated by the present invention, and the effects according to the present invention are not limited to those described in the embodiments. It should be noted that the above-described embodiment and the below-described modified embodiments can be appropriately combined and used, but detailed description thereof will be omitted.

(Modified form)
(1) In the above-described embodiment, the example in which the interior sheet is used as the interior member such as the wall member 10 of the building room 1 is shown, but the present invention is not limited to this. The interior seat may be applied to an interior interior member such as a driver's seat of vehicles such as automobiles (passenger cars, buses, etc.), railroads, airplanes, and passenger seats.
By applying the interior seat to the interior of the vehicle, as in the case of the room 1 described above, heat can be suppressed from being stored in the interior members of the vehicle as much as possible, and the temperature of the indoor space can be controlled more effectively. It can be performed quickly, and the temperature inside the room can be made comfortable.
When an interior seat is used for a passenger car, an interior seat having the same layer structure as the interior seat 40 used for the floor member 30 is used from the viewpoint of ensuring scratch resistance and waterproofness. Is desirable.

(2) In the above-described embodiment, the example in which the base material layer 22 of the interior sheet 20 provided on the wall member 10 is formed in a porous shape has been shown, but the present invention is not limited to this. The base material layer 22 may be a resin sheet in which a resin having a small number of pores or a resin having no pores is dense and cured. In this case, the base material layer 22 is preferably formed in a thickness range of 100 to 700 μm in a state of being laminated with the backing sheet 21.
