Description

  The present invention relates to a thermal barrier cloth, and more particularly to a thermal barrier cloth suitable as a roll screen, a curtain or the like.

  A roll screen and a curtain are installed in the room near the window glass which separates the room interior and exterior. In order to improve these heat shielding properties, attempts have been made to bond a heat shielding film to the cloth (Patent Document 1).

JP 05-272279 A

  When a bending force is applied to the fabric to which the heat shielding film is bonded, a bent portion may be generated in the fabric, and the appearance of the product may be deteriorated. Moreover, peeling may occur between the heat shielding film and the fabric, which may deteriorate the appearance of the product. Furthermore, there is a possibility that the adhesive used for lamination bonds (blocks) between the fabric and the heat shielding film laminated to the other fabric or the other fabric.

  The problem to be solved by the present invention is to provide a heat shielding cloth in which appearance deterioration due to bending or peeling of the fabric and blocking due to an adhesive are suppressed.

  In order to solve the above problems, the heat shielding cloth according to the present invention comprises a fabric, an adhesive layer, and a heat shielding laminate in this order, and the heat shielding laminate has a metal layer and a resin film. The metal layer is disposed closer to the adhesive layer than the resin film, and the adhesive layer penetrates the fabric from the surface of the fabric in contact with the adhesive layer, and the amount of permeation is the same as that of the resin film. The gist is that it is in the range of 5 to 80% of the thickness of the fabric.

  The Young's modulus of the adhesive layer is preferably in the range of 0.5 to 100 MPa. The adhesive layer preferably contains at least one of a polyester-based adhesive, an acrylic-based adhesive, a urethane-based adhesive, an epoxy-based adhesive, and a silicone-based adhesive. It is preferable that the heat shielding laminate further includes a thermoplastic resin layer, and the thermoplastic resin layer is disposed closer to the adhesive layer than the metal layer. The thickness of the heat shield laminate is preferably 50 μm or more. It is preferable that the said thermal barrier laminated body further has a cured layer which consists of curable materials, and the said cured layer is arrange | positioned as outermost layer by the side of the said resin-made films. It is preferable that the said hardened layer has an unevenness | corrugation in the outer surface, and the ratio of the difference of the largest thickness of the said hardened layer and the minimum thickness with respect to the largest thickness of the said hardened layer is 4% or more. The resin film is preferably a polyolefin film. The resin film is preferably a biaxially stretched polypropylene film.

  According to the thermal barrier cloth of the present invention, the adhesive layer bonding the fabric and the thermal barrier laminate penetrates the fabric from the surface in contact with the adhesive layer of the fabric, and the amount of penetration is 5% of the thickness of the fabric. Since it exists in the range of -80%, blocking by the bending of a cloth, the appearance deterioration by peeling, and an adhesive agent is suppressed.

FIG.

  The heat insulating cloth according to the present invention will be described in detail with reference to the drawings.

  First, a heat insulating cloth according to a first embodiment of the present invention will be described.

  FIG. 1 is a cross-sectional view of a heat shielding cloth according to a first embodiment of the present invention. The heat shield cloth 10 is formed of (laminated) a fabric 12, an adhesive layer 14, and a heat shield laminate 16 in this order. The heat shield laminate 16 is bonded to the fabric 12 by the adhesive layer 14 and integrated with the fabric 12. The heat shield laminate 16 has a metal layer 18 and a resin film 20. The metal layer 18 is disposed closer to the adhesive layer 14 than the resin film 20. In the thermal barrier laminate 16, the metal layer 18 is in contact with the adhesive layer 14, and the resin film 20 covers the surface of the metal layer 18 and is exposed on the surface. The adhesive layer 14 penetrates the fabric 12 from the surface of the fabric 12 in contact with the adhesive layer 14.

The fabric 12 is a thin and wide sheet of fibers, and includes textiles, knits, laces, felts, non-woven fabrics and the like. Among these, non-woven fabrics are preferable from the viewpoint of being excellent in cost and easily infiltrating the adhesive layer 14 into the fabric 12. It is preferable that the fabric 12 be relatively thin in terms of daylighting and flexibility. The thickness of the fabric 12 is preferably 1000 μm or less from the viewpoint of light collection, flexibility and the like. More preferably, it is 700 micrometers or less, More preferably, it is 500 micrometers or less. Moreover, it is preferable that it is 50 micrometers or more from a viewpoint of the ease of manufacture in the manufacture process in which the contact bonding layer 14 is infiltrated to the cloth 12. More preferably, it is 70 micrometers or more, More preferably, it is 100 micrometers or more. The fabric 12 preferably has a basis weight of 40 g / m ² or more from the viewpoint of suppressing the deterioration of the appearance of the heat shield laminate 16 due to the metal layer 18. More preferably, it is 50 g / m ² or more, more preferably 60 g / m ² or more. Moreover, it is preferable that a fabric weight is 400 g / m < ² > or less from a viewpoint of daylighting property, flexibility, etc. More preferably, it is 300 g / m ² or less, more preferably 200 g / m ² or less.

  In the heat shield cloth 10, for example, a bending force may be applied to the cloth 12 to which the heat shield laminate 16 is bonded, as in the case of being wound around a core rod as a roll screen. FIG. 2 (a) shows the heat shield cloth 10 in a state before a bending force is applied, and FIG. 2 (b) shows the heat shield cloth 10 in a state in which a bending force is applied. As shown in FIG. 2 (b), when a bending force is applied to the fabric 12 to which the heat shield laminate 16 is bonded, a tensile stress is generated on the outside of the fabric 12. Then, as shown in FIG. 2C, there is a possibility that the bending portion 12a is generated in the fabric 12 due to the tensile stress. This may cause the appearance of the product to deteriorate. The larger the fabric weight of the fabric 12, the easier it is for the fabric 12 to have such a bent portion 12a.

  When the thermal barrier laminate 16 to be bonded to the cloth 12 is thickened, the stress of the cloth 12 due to the bending force is relieved, and the bending of the cloth 12 is easily suppressed. From this viewpoint, the thickness of the heat shield laminate 16 is preferably 50 μm or more. More preferably, it is 60 micrometers or more, More preferably, it is 70 micrometers or more. On the other hand, it is preferable that the thickness of the thermal insulation laminated body 16 is 125 micrometers or less from a viewpoint of ensuring a softness | flexibility. More preferably, it is 100 micrometers or less, More preferably, it is 75 micrometers or less. The thickness of the thermal barrier laminate 16 is the total thickness of the metal layer 18 and the resin film 20. Since the metal layer 18 is formed of a metal thin film, it can be said that the thickness of the thermal barrier laminate 16 is substantially equal to the thickness of the resin film 20.

  Further, in the heat shield cloth 10, a bending force may be applied to the heat shield laminated body 16 as in the case of being wound around a core rod as a roll screen, for example. FIG. 3 (a) shows the heat shield cloth 10 in a state before a bending force is applied, and FIG. 3 (b) shows the heat shield cloth 10 in a state in which a bending force is applied. As shown in FIG. 3 (b), when a bending force is applied to the fabric 12 to which the heat shield laminate 16 is bonded, a compressive stress is generated inside the heat shield laminate 16. When the compressive stress is released toward the inside of the heat shield laminate 16, as shown in FIG. 3C, a bent portion 16a is generated in the heat shield laminate 16 and the adhesive layer 14. Since the adhesive force between the adhesive layer 14 and the fabric 12 is weaker than the adhesive force between the adhesive layer 14 and the thermal barrier laminate 16, peeling occurs in this portion (between the adhesive layer 14 and the fabric 12) to form air bubbles. The appearance of the product may be deteriorated. As the heat shield laminate 16 becomes thicker, the compressive stress becomes larger, and the peeling is likely to occur.

  In the present invention, the adhesive layer 14 penetrates the fabric 12 from the surface of the fabric 12 in contact with the adhesive layer 14. In FIG. 1, the area from the surface of the fabric 12 in contact with the adhesive layer 14 to the dotted line in the fabric 12 is the penetration range of the adhesive layer 14 into the fabric 12. As a result, even when the heat shield laminate 16 is thickened, peeling of the fabric 12 due to the release of the compressive stress can be suppressed. The penetration amount of the adhesive layer 14 is 5% or more of the thickness of the fabric 12. Thereby, the adhesion between the adhesive layer 14 and the fabric 12 is secured to suppress the peeling of the fabric 12. In this respect, the penetration amount of the adhesive layer 14 is preferably 10% or more of the thickness of the fabric 12 and more preferably 20% or more of the thickness of the fabric 12. On the other hand, if the amount of penetration of the adhesive layer 14 into the fabric 12 is too large, the adhesive component of the adhesive layer 14 passes through the fabric 12 and the overlapping heat shield cloths, for example, when the roll screen is wound around the core bar. The resin film 20 of the heat shield laminate 16 of one of the heat shield cloths 10 and the fabric 12 of the other heat shield cloth 10 are adhered (blocked) by the adhesive component of the adhesive layer 14. From the viewpoint of suppressing such blocking, the penetration amount of the adhesive layer 14 is set to 80% or less of the thickness of the fabric 12. Also, from this point of view, the penetration amount of the adhesive layer 14 is preferably 65% or less of the thickness of the fabric 12, more preferably 50% or less of the thickness of the fabric 12.

  The adhesive layer 14 can penetrate the fabric 12 in the process of manufacturing the heat shield cloth 10. The heat shield cloth 10 can be manufactured by bonding the cloth 12 and the heat shield laminated body 16 via the adhesive layer 14. An example of the manufacturing process of the heat insulating cloth 10 is shown in FIG. First, as shown in FIG. 4A, the material for forming the adhesive layer 14 is applied to the surface of the metal layer 18 of the heat shield laminate 16 to a predetermined thickness to form the layer 14a made of the material for formation. At this time, a drying process etc. are performed as needed. Next, as shown in FIG. 4 (b), the surface of the layer 14 a made of the forming material and the surface of the fabric 12 are aligned. Then, as shown in FIG. 4 (c), pressure is applied to push the forming material into the interior of the fabric 12 to penetrate it. Thereafter, crosslinking treatment, curing treatment and the like are performed as necessary. Thus, the heat shield cloth 10 in which the adhesive layer 14 penetrates the cloth 12 is manufactured.

  The material for forming the adhesive layer 14 is composed of a material containing an adhesive or a pressure-sensitive adhesive. The material for forming the adhesive layer 14 may be a material containing both an adhesive and an adhesive. The adhesive exerts a peeling resistance upon solidification, and the adhesive adheres under pressure using pressure on the surface (pressure-sensitive adhesive), and these are distinguished.

  The material for forming the adhesive layer 14 preferably has an appropriate viscosity when it is infiltrated into the fabric 12. If the viscosity is too high, it will be difficult to penetrate the fabric 12. If the viscosity is too low, it will leave the fabric 12 and cause blocking. Having a suitable viscosity allows the fabric 12 to penetrate so as not to slip out of the fabric 12. Further, the amount of penetration can be adjusted by the pressing force. The viscosity of the forming material upon penetration into the fabric 12 may be adjusted by heating, dilution with a solvent, or the like. The material for forming the adhesive layer 14 preferably has excellent adhesion to the fabric 12 after it has penetrated the fabric 12. The ease of penetration into the fabric 12 and the excellent adhesion to the fabric 12 are contradictory properties, but for example, for an adhesive or a pressure-sensitive adhesive made of a thermoplastic resin, warming when penetrating into the fabric 12 Such conditions may be met by such as. In addition, in the case of an adhesive or a pressure-sensitive adhesive made of a crosslinkable or curable resin, such a condition may be satisfied if it is, for example, in the form of a gel when permeating the fabric 12.

  Examples of the adhesive include polyester-based adhesives, acrylic-based adhesives, urethane-based adhesives, epoxy-based adhesives, silicone-based adhesives and the like. These may be used alone as an adhesive, or may be used in combination of two or more. Examples of the pressure-sensitive adhesive include acrylic resin-based pressure-sensitive adhesives, silicone resin-based pressure-sensitive adhesives, and urethane-based pressure-sensitive adhesives. These may be used alone as an adhesive, or may be used in combination of two or more. Among these, an adhesive is more preferable from the viewpoint of a manufacturing process or the like which penetrates the fabric 12. Among the adhesives, polyester-based adhesives and epoxy-based adhesives are more preferable from the viewpoint of crosslinking treatment, curing treatment and the like.

  The Young's modulus of the adhesive layer 14 is preferably 0.5 MPa or more. More preferably, it is 1.0 MPa or more, more preferably 3.0 MPa or more. Thereby, peeling due to cohesive failure can be suppressed. The Young's modulus of the adhesive layer 14 is preferably 100 MPa or less. More preferably, it is 80 MPa or less, more preferably 70 MPa or less. This facilitates penetration into the fabric.

  The thickness of the adhesive layer 14 is preferably 5 μm or more from the viewpoint of securing the amount of permeation to the fabric 12 and securing the adhesiveness to the fabric 12. More preferably, it is 10 micrometers or more, More preferably, it is 15 micrometers or more. On the other hand, from the viewpoint of easily suppressing blocking, the thickness is preferably 130 μm or less. More preferably, it is 105 micrometers or less, More preferably, it is 80 micrometers or less. The thickness of the adhesive layer 14 is measured including the portion penetrating the fabric 12.

  In the heat shield laminate 16, the resin film 20 can be used as a base on which the metal layer 18 is formed. In the heat shield laminate 16, the resin film 20 is in contact with the metal layer 18. The film is in the form of a thin film and generally has a thickness of 200 μm or less or 250 μm or less. What is necessary is just to have a degree of flexibility enough to be rolled, and as such, it may be 200 μm or more or 250 μm or more thick. The film is generally delivered as a roll.

  As a material of the resin film 20, a thin film can be formed on the surface without any trouble, and a material having flexibility is preferable. In addition, from the viewpoint of satisfying the light collecting property without impairing the light collecting property of the fabric 12, a material having transparency is preferable. Specific examples of the material of the resin film 20 include polyesters such as polyethylene terephthalate / polyethylene naphthalate / polybutylene terephthalate, polycarbonates, polyolefins such as polymethyl methacrylate, polyethylene / polypropylene / cycloolefin polymers, and ethylene-vinyl acetate Copolymers, polystyrene, polyamide, polyetheretherketone, polyvinyl chloride, polyvinylidene chloride, triacetyl cellulose, polyurethane and the like can be mentioned. These may be used alone or in combination of two or more. Among these, polyester, polyolefin, polycarbonate and polymethyl methacrylate are mentioned as more preferable materials from the viewpoint of being excellent in transparency, durability, processability and the like. Moreover, polyolefin is mentioned as a more preferable material from a viewpoint which is more excellent in a softness | flexibility. Among polyolefins, polypropylene is preferable from the viewpoint of excellent transparency. In particular, biaxially oriented polypropylene (OPP) is preferred.

  The thickness of the resin film 20 is from the viewpoint of suppressing the absorption of infrared rays, from the viewpoint of flexibility, from the viewpoint of suppressing the functional deterioration (deterioration) of the metal layer 18 by covering the metal layer 18, the strength as a substrate for forming the metal layer 18 It is preferable to be in a predetermined range from the viewpoint of For example, when it consists of a polyolefin film with comparatively small absorption of infrared rays, it is preferable that it is 60 micrometers or less from a viewpoint of suppressing absorption of infrared rays and ensuring a softness | flexibility. More preferably, it is 50 μm or less. Moreover, it is preferable that it is 10 micrometers or more from a viewpoint of the intensity | strength which forms the metal layer 18 which suppresses the functional fall (deterioration) of the metal layer 18. More preferably, it is 15 μm or more. For example, in the case of a polyester film having relatively large infrared absorption, the thickness is preferably 50 μm or less from the viewpoint of suppressing the infrared absorption and securing flexibility. More preferably, it is 25 μm or less. Further, from the viewpoint of the strength of forming the metal layer 18 to suppress the functional deterioration (deterioration) of the metal layer 18, the thickness is preferably 5 μm or more. More preferably, it is 10 μm or more. Since the polyester film is relatively strong, even if it is thin like this, the strength as a substrate can be secured.

  In the heat shield laminate 16, the resin film 20 can cover and protect the surface of the metal layer 18. The protection of the metal layer 18 covers the surface of the metal layer 18, thereby suppressing the abrasion of the metal layer 18, suppressing the corrosion of the metal layer 18 due to moisture, and the like. The resin film 20 functions as a protective layer for the metal layer 18 to suppress the deterioration of the metal layer 18 and to suppress the decrease in infrared reflectivity (the function deterioration of the metal layer) with time.

  In the heat shield laminate 16, the metal layer 18 is made of a metal that easily reflects infrared rays (heat rays), and functions as a solar radiation shielding layer and a heat insulating layer. The metal layer 18 may be formed as a continuous continuous layer on the entire surface of the substrate (resin film 20) for forming the metal layer 18, or in the form of stripes on the surface of the substrate (resin film 20). It may be formed as a discontinuous layer such as island shape (dot shape).

  As the metal of the metal layer 18, metals such as silver, gold, platinum, copper, aluminum, chromium, titanium, zinc, tin, nickel, cobalt, niobium, tantalum, tungsten, zirconium, lead, palladium, indium, and the like Alloys and the like. One or more of these may be contained. Among these, silver and silver alloys are preferable from the viewpoint of excellent transparency and heat ray reflectivity. In addition, a silver alloy is preferable from the viewpoint of improving the durability to environment such as heat, light, water vapor and the like.

  In the metal layer 18, the silver alloy is preferably a silver alloy containing silver as a main component and at least one metal element such as copper, bismuth, gold, palladium, platinum, titanium and the like. More preferably, a silver alloy containing copper (Ag-Cu alloy), a silver alloy containing bismuth (Ag-Bi alloy), a silver alloy containing titanium (Ag-Ti alloy) or the like is preferable. There are advantages such as a large diffusion suppressing effect of silver and advantageous in cost. The proportion of subelements such as copper, bismuth and titanium in the metal layer 18 can be measured using ICP analysis.

  When a silver alloy containing copper is used, the content of copper is preferably 1 atomic% or more, more preferably 2 atomic% or more, and still more preferably 3 atomic% or more, from the viewpoint of obtaining the addition effect. On the other hand, it is preferably 20 atomic% or less, more preferably 10 atomic% or less, still more preferably 5 atomic% or less from the viewpoint of productivity such as easy to secure high transparency, easy production of a sputter target, etc. .

  When using a silver alloy containing bismuth, the content of bismuth is preferably 0.01 atomic% or more, more preferably 0.05 atomic% or more, still more preferably 0.1 atomic% or more, from the viewpoint of obtaining addition effect. It is. On the other hand, it is preferably 5 atomic% or less, more preferably 2 atomic% or less, and still more preferably 1 atomic% or less from the viewpoint of manufacturability such as easy production of a sputter target.

  When a silver alloy containing titanium is used, the content of titanium is preferably 0.01 atomic% or more, more preferably 0.05 atomic% or more, and still more preferably 0.1 atomic% or more from the viewpoint of obtaining addition effect It is. On the other hand, in the case of using a film, it is preferably 2 atomic% or less, more preferably 1.75 atomic% or less, and still more preferably 1.5 atomic% or less, from the viewpoint that a complete solid solution is easily obtained.

  In the case of using a silver alloy containing copper, bismuth or titanium, in addition to silver, copper, bismuth, or titanium, for example, other elements or unavoidable impurities may be added as long as the aggregation / diffusion suppression effect of silver is not adversely affected.

  The thickness of the metal layer 18 is preferably 2 nm or more, more preferably 3 nm or more, and still more preferably 4 nm or more, from the viewpoint of stability, heat ray reflectivity and the like. Further, from the viewpoint of transparency, economy and the like, it is preferably 50 nm or less, more preferably 30 nm or less, and still more preferably 20 nm or less. In the case where the metal layer 18 is a discontinuous layer such as a stripe or a dot, transparency can be ensured even when the thickness exceeds 50 nm. Thus, if the metal layer 18 is a non-continuous layer, thicknesses greater than 50 nm are also suitable.

  The metal layer 18 can be formed by a method such as vacuum evaporation, sputtering, ion plating, MBE, laser ablation, thermal CVD, plasma CVD or the like. From the viewpoint of obtaining a dense film and easy control of the film thickness, sputtering methods such as DC magnetron sputtering method and RF magnetron sputtering method are more preferable.

  The thermal barrier laminate 16 is obtained, for example, by forming a metal thin film on one surface of the resin film 20 by a predetermined thin film forming method to form the metal layer 18.

  In the heat shield cloth 10, the heat shield laminate 16 may or may not be transparent. Transparent (light transmission) means that the transmittance (visible light transmittance) in the wavelength region of 360 to 830 nm is 50% or more. Due to the transparency of the heat shield laminate 16, in the heat shield cloth 10, the heat shield laminate 16 does not impair the light collecting property of the fabric 12. This makes it possible to satisfy the daylighting performance. The transparency of the heat shield laminate 16 can be ensured by the fact that the resin film 20 is transparent and the metal layer 18 is transparent.

The heat shield laminate 16 is preferably excellent in flexibility. Due to the flexibility of the thermal barrier laminate 16, in the thermal barrier cloth 10, the thermal barrier laminate 16 does not impair the flexibility of the fabric 12. By this, flexibility can be satisfied. Therefore, the light shielding cloth 10 can satisfy the light collecting property, the heat shielding property and the heat insulating property without impairing the softness of the fabric 12. The flexibility of the heat shield laminate 16 is represented by the bending resistance. The thermal barrier laminate 16 is set to a value such that its bending resistance does not deviate too much from the bending resistance of the fabric 12 so as not to impair the flexibility of the fabric 12. As a result, the heat shield cloth 10 can be made excellent in flexibility without impairing the flexibility of the fabric 12. The index of the flexibility of the heat shield laminate 16 is represented by a value A of the following equation (1). In the heat shield cloth 10, A may be 120% or less.
(Formula 1)
A (%) = {(stiffness of heat shield laminate 16−stiffness of fabric 12) / stiffness of fabric 12} × 100
However, the bending resistance is measured in accordance with JIS L 1096 A method (45 ° cantilever method).

  From the viewpoint of increasing the flexibility of the heat shield cloth 10, the above A is preferably 120% or less. More preferably, it is 110% or less.

  The flexibility of the heat shield laminate 16 is influenced by the material, thickness and the like of the resin film 20. For this reason, in order to set the flexibility of the thermal barrier laminate 16 within a specific range, it is preferable to make the material, thickness, etc. of the resin film 20 of the thermal barrier laminate 16 suitable. The material and thickness of the resin film 20 also affect the infrared absorptivity of the resin film 20. Therefore, from the viewpoint of the bending resistance of the heat shield laminate 16 and the infrared absorptivity of the resin film 20, the material and thickness of the resin film 20 may be made suitable.

  According to the thermal barrier cloth 10 having the above configuration, the adhesive layer 14 adhering the fabric 12 and the thermal barrier laminate 16 penetrates the fabric 12 from the surface in contact with the adhesive layer 14 of the fabric 12, and the permeation thereof Since the amount is 5% or more of the thickness of the fabric 12, even if the thermal barrier laminate 16 is thickened, the appearance deterioration due to the peeling of the fabric 12 can be suppressed. And since the thermal insulation laminated body 16 can be thickened, the appearance deterioration by bending of the cloth 12 is suppressed even if the fabric weight of the cloth 12 is increased. Moreover, since the penetration amount of the adhesive layer 14 is 80% or less of the thickness of the fabric 12, blocking by the adhesive is suppressed. Therefore, the appearance deterioration due to bending and peeling of the fabric 12 and the blocking due to the adhesive can be suppressed. And since the fabric weight of the cloth 12 can be increased, the appearance deterioration by the metal layer 18 is suppressed. In addition, the penetration of the adhesive layer 14 into the fabric 12 tends to lower the flexibility of the thermal barrier cloth 10 (the bending resistance of the thermal barrier cloth 10 tends to increase), but the penetration amount of the adhesive layer 14 Since the thickness of the fabric 12 is 80% or less of the thickness of the fabric 12, the decrease in the flexibility of the heat shield cloth 10 is acceptable, and the flexibility of the heat shield cloth 10 is secured.

  The heat shield cloth 10 integrates the heat shield laminate 16 into the fabric 12 to ensure the light collecting property without impairing the softness of the fabric 12, and is desired by the heat shield property and the heat insulation property of the heat shield laminate 16. Satisfying the heat shield and heat insulation of At this time, from the viewpoint of maintaining the original design of the fabric 12, the heat shield cloth 10 directs the fabric 12 to the indoor side and the heat shield laminate 16 to the indoor side in the room near the window glass separating the indoor and outdoor Will be placed towards. An air layer is formed between the heat shield cloth 10 and the window glass, and since the heat shield cloth 10 is provided with the heat shield laminate 16, this air layer functions as a heat insulation layer, which also enhances the heat insulation effect. .

  Next, a heat shield cloth according to a second embodiment of the present invention will be described.

  FIG. 5 shows a heat shield cloth according to a second embodiment of the present invention. The heat shield cloth 30 which concerns on 2nd embodiment consists of what has the cloth 12, the contact bonding layer 14, and the heat shield laminated body 26 in this order (laminated). The heat shield laminate 26 is bonded to the fabric 12 by the adhesive layer 14 and integrated with the fabric 12. The thermal barrier laminate 26 comprises (laminated) a resin film 20, a metal layer 18, an adhesive layer 22, and a thermoplastic resin layer 24 in this order. The metal layer 18 is disposed closer to the adhesive layer 14 than the resin film 20. The thermoplastic resin layer 24 is disposed closer to the adhesive layer 14 than the metal layer 18. In the heat shield laminate 26, the thermoplastic resin layer 24 is in contact with the adhesive layer 14, and the resin film 20 covers the surface of the metal layer 18 and is exposed on the surface. The adhesive layer 14 penetrates the fabric 12 from the surface of the fabric 12 in contact with the adhesive layer 14.

  The heat shield cloth 30 according to the second embodiment shown in FIG. 5 is different from the heat shield cloth 10 according to the first embodiment shown in FIG. 1 in the adhesive layer 22 different from the adhesive layer 14 and the thermoplastic resin layer The difference is the same as that of the heat shield cloth 10 according to the first embodiment, except for the point having the reference numeral 24. Therefore, the description of the configuration other than the above is omitted.

  The thermoplastic resin layer 24 is disposed closer to the adhesive layer 14 than the metal layer 18. That is, the surface on the fabric 12 side of the metal layer 18 is covered with the thermoplastic resin layer 24. The fabric 12 is a thin and wide sheet of fibers, so it is easy to allow moisture to pass through the mesh. The thermoplastic resin layer 24 covering the surface of the metal layer 18 on the side of the fabric 12 is a waterproof layer, whereby the corrosion of the metal layer 18 due to moisture permeation from the fabric 12 is further suppressed, and the durability is superior (deterioration of function Can be reduced). In addition, with respect to the moisture from the surface (resin film 20) side on the opposite side to the cloth 12, as described above, the resin film 20 functions as a waterproof layer. Therefore, in the heat insulating cloth 30, moisture permeation from any of both sides can be suppressed.

  The thickness of the thermoplastic resin layer 24 is preferably 5 μm or more from the viewpoint of waterproofness. More preferably, it is 10 μm or more. Moreover, it is preferable that it is 50 micrometers or less from a viewpoint of a softness | flexibility and transparency. More preferably, it is 40 μm or less.

The material of the adhesive layer 22 is appropriately determined and used from the pressure-sensitive adhesive and the adhesive shown in the adhesive layer 14. The material of the adhesive layer 22 may be the same as or different from the material of the adhesive layer 14. The thickness of the adhesive layer 22 may be in the same range as the adhesive layer 14 in consideration of transparency, flexibility, and adhesiveness.

  The thermal barrier laminate 26 in the second embodiment further includes an adhesive layer 22 different from the adhesive layer 14 and a thermoplastic resin layer 24 as compared to the thermal barrier laminate 16 in the first embodiment. Therefore, the thickness of the thermal barrier laminate 26 in the second embodiment is the total thickness of the metal layer 18, the resin film 20, the adhesive layer 22, and the thermoplastic resin layer 24. The thickness of the thermal barrier laminate 26 is preferably 50 μm or more from the viewpoint of easily suppressing the bending of the fabric 12 as in the thermal barrier laminate 16. More preferably, it is 60 micrometers or more, More preferably, it is 70 micrometers or more.

  The heat shield cloth 30 which concerns on 2nd embodiment shown in FIG. 5 can be manufactured as follows. In FIG. 6, an example of the manufacturing process of the heat insulation cloth 30 is shown. First, as shown in FIG. 6A, the material for forming the adhesive layer 14 is applied to the surface of the thermoplastic resin layer 24 to a predetermined thickness to form the layer 14a made of the material for formation. At this time, a drying process etc. are performed as needed. Further, the material for forming the adhesive layer 22 is applied to a predetermined thickness on the surface of the metal layer 18 of the laminate having the metal layer 18 on the surface of the resin film 20 to form the adhesive layer 22. At this time, a drying process etc. are performed as needed. Next, as shown in FIG. 6 (b), the surface of the layer 14 a made of the material for forming the adhesive layer 14 and the surface of the fabric 12 are aligned. Then, as shown in FIG. 6 (c), pressure is applied to push the material for forming the adhesive layer 14 into the interior of the fabric 12 to penetrate it. Thereafter, crosslinking treatment, curing treatment and the like are performed as necessary. Then, as shown in FIG. 6D, the surface of the adhesive layer 22 and the surface of the thermoplastic resin layer 24 are aligned. Thereafter, crosslinking treatment, curing treatment and the like are performed as necessary. As described above, the thermal barrier laminate 26 comprising the resin film 20, the metal layer 18, the adhesive layer 22, and the thermoplastic resin layer 24 in this order (laminated) is adhered to the fabric 12 by the adhesive layer 14. A heat shield cloth 30 is obtained, which is formed (laminated) of the cloth 12, the adhesive layer 14, and the heat shield laminate 26 in this order, which is integrated with the cloth 12.

  In the manufacturing process of the heat shielding cloth 30, the drying process at the time of forming the layer 14a which consists of a formation material is performed by heating. Then, the material of the thermoplastic resin layer 24 is preferably one having excellent heat resistance. From this point of view, polyester, polyolefin, polyvinyl alcohol, polycarbonate and the like are preferable as the material of the thermoplastic resin layer 24. Among these, polyethylene terephthalate (PET) is more preferable.

  According to the heat shield cloth 30 having the above configuration, as in the heat shield cloth 10, the appearance deterioration due to bending and peeling of the cloth 12 and the blocking due to the adhesive can be suppressed. And since the fabric weight of the cloth 12 can be increased, the appearance deterioration by the metal layer 18 is suppressed.

  Further, the heat shielding cloth 30 integrates the heat shielding laminated body 26 into the fabric 12 to secure the light collecting property without impairing the flexibility of the cloth 12, and the heat shielding property and the heat insulating property of the heat shielding laminated body 26. Thus, the desired heat shielding and heat insulating properties are satisfied. At this time, from the viewpoint of maintaining the original design of the cloth 12, the heat shielding cloth 30 directs the cloth 12 to the indoor side and the heat shielding laminate 26 on the indoor side in the room near the window glass separating the indoor and outdoor. Will be placed towards. An air layer is formed between the heat shield cloth 30 and the window glass, and since the heat shield cloth 30 includes the heat shield laminate 26, this air layer functions as a heat insulation layer, which also enhances the heat insulation effect. .

  In the present invention, a barrier layer may be formed on one or both of the surface on the resin film 20 side of the metal layer 18 and the surface on the adhesive layer 14 side. FIG. 7 shows a heat shield cloth in which a barrier layer is formed on both the surface on the resin film 20 side of the metal layer 18 and the surface on the adhesive layer 14 side.

The adhesive layer 14 penetrates the fabric 12 from the surface of the fabric 12 in contact with the adhesive layer 14.

  As shown in FIG. 7 (b), the heat shield cloth 50 according to another embodiment of the present invention has a cloth 12, an adhesive layer 14 and a heat shield laminate 38 in this order (laminated) ) It consists of things. The heat shield laminate 38 is bonded to the fabric 12 by the adhesive layer 14 and is integrated with the fabric 12. The thermal barrier laminate 38 comprises (laminated) a resin film 20, a barrier layer 32, a metal layer 18, a barrier layer 34, an adhesive layer 22, and a thermoplastic resin layer 24 in this order.

The adhesive layer 14 penetrates the fabric 12 from the surface of the fabric 12 in contact with the adhesive layer 14.

  The barrier layers 32 and 34 improve the adhesion of the metal layer 18. In addition, transfer of the metal of the metal layer 18 to other layers is suppressed. The barrier layers 32 and 34 are metal-containing layers containing metal. The metal contained in the barrier layers 32 and 34 is preferably a metal that easily reacts with a hydroxyl group or an oxygen group. Such a metal is a metal that forms a passive state, and specifically, Si, Ti, Zr, Al, Cr, Ni, Fe and the like can be mentioned. Among these, Si, Ti, and Zr are more preferable from the viewpoints of reactivity with a hydroxyl group and an oxygen group, film formation processability, and the like.

  Similar to the metal layer 18, the barrier layers 32 and 34 can be formed using a vapor phase method such as physical vapor deposition (PVD) or chemical vapor deposition (CVD). Thus, a thin film having a thickness of several nm to several tens of nm, which can form a dense film, can be formed with a uniform film thickness. Examples of physical vapor deposition (PVD) include vacuum evaporation, sputtering, ion plating, MBE, and laser ablation. Examples of the chemical vapor deposition (CVD) include thermal CVD and plasma CVD. Among them, the sputtering method is particularly preferable from the viewpoint of obtaining a dense film and relatively easy control of the film thickness.

The barrier layers 32 and 34 may be any of a layer of metal, a layer of metal and metal oxide, and a layer of metal oxide. The post-oxidation treatment can be carried out, for example, by performing heat treatment or the like on the thermal barrier laminate in an atmosphere in which oxygen and moisture are present, such as in the air, in a high oxygen atmosphere, or in a high humidity atmosphere.

As such a layer, a cured layer made of a curable material and the like can be mentioned. FIG. 8 shows a heat shield cloth having a cured layer made of a curable material. FIG. 8A shows a heat shield cloth 60 in which a hardened layer is added to the heat shield cloth 10 shown in FIG. FIG. 8 (b) is to add a hardened layer to the heat shield cloth 30 shown in FIG. 5, and shows a heat shield cloth 70.

  As shown in FIG. 8 (a), the heat shield cloth 60 according to another embodiment of the present invention has a cloth 12, an adhesive layer 14, and a heat shield laminate 44 in this order (laminated) ) It consists of things. The heat shield laminate 44 is bonded to the fabric 12 by the adhesive layer 14 and integrated with the fabric 12. The thermal barrier laminate 44 is composed of (hardened) the cured layer 42, the resin film 20, and the metal layer 18 in this order.

  As shown in FIG. 8 (b), the heat shield cloth 70 according to another embodiment of the present invention has a cloth 12, an adhesive layer 14, and a heat shield laminate 46 in this order (laminated ) It consists of things. The thermal barrier laminate 46 is bonded to the fabric 12 by the adhesive layer 14 and integrated with the fabric 12. The thermal barrier laminate 46 comprises (laminated) a cured layer 42, a resin film 20, a metal layer 18, an adhesive layer 22, and a thermoplastic resin layer 24 in this order. The metal layer 18 is disposed closer to the adhesive layer 14 than the hardened layer 42 and the resin film 20. The hardened layer 42 is disposed as the outermost layer on the resin film 20 side, and the hardened layer 42 is exposed on the surface. The thermoplastic resin layer 24 is disposed closer to the adhesive layer 14 than the metal layer 18. In the heat shield laminate 46, the thermoplastic resin layer 24 is in contact with the adhesive layer 14. The adhesive layer 14 penetrates the fabric 12 from the surface of the fabric 12 in contact with the adhesive layer 14.

As the inorganic compound, silicon oxide, titanium oxide, zirconium oxide and the like can be mentioned. The cured layer 42 can be formed, for example, by applying a coating solution containing a curable material on the surface of the resin film 20 and then performing a predetermined curing process.

More preferably, it is 0.3 micrometer or more, More preferably, it is 0.5 micrometer or more.

  Since silicon oxide is harder than acrylic resin and silicone resin, the thickness of the hardened layer 42 can be made thinner from the viewpoint of securing scratch resistance. That is, absorption of infrared rays can be suppressed more than curable resin, maintaining abrasion resistance. Silicon oxide may be cured from a silicon alkoxide by a sol-gel method, or may be cured from a silazane by a hydrolysis reaction. From the viewpoint of small curing shrinkage, silazane is preferably used as a raw material. The silazane includes an organic polysilazane containing an organic group (hydrocarbon group) and an inorganic polysilazane (such as perhydropolysilazane) not containing an organic group (hydrocarbon group). An organic component remains in the cured product of the organic polysilazane by hydrolysis. The Young's modulus of the cured product can be adjusted by the amount of the remaining organic component. The thickness of the hardened layer 42 made of silicon oxide is preferably 10.0 μm or less from the viewpoint of suppressing absorption of infrared rays and securing flexibility. More preferably, it is 5.0 μm or less. Moreover, it is preferable that it is 0.2 micrometer or more from a viewpoint of suppressing the functional fall (deterioration) of the metal layer 18, and being excellent in abrasion resistance.

  The organic-inorganic hybrid material is formed of an organic material (raw material of organic component) and an inorganic material (raw material of inorganic component), and the organic material and the inorganic material are complexed at nano level or molecular level. In the organic-inorganic hybrid material, for example, a network-like crosslinked structure in which an inorganic material and an organic material dispersed in the organic material cause a reaction such as a polymerization reaction, and an inorganic component is highly dispersed in the organic component via a chemical bond. The When the hardened layer 42 is made of an organic-inorganic hybrid material, the adhesion to the resin film 20 is improved. It is presumed that this is because the curing shrinkage of the hardened layer 42 is suppressed by adding the inorganic component to the material forming the hardened layer 42.

  As a raw material of the organic component which forms an organic inorganic hybrid material, curable resin etc. are mentioned. As a curable resin, an acrylic resin, an epoxy resin, a urethane resin, etc. are mentioned. These may be used alone or in combination of two or more.

  The compounding ratio of the raw material of the inorganic component forming the organic-inorganic hybrid material is preferably 10% by mass or more from the viewpoint of adhesion with the inner layer 22. More preferably, it is 40 mass% or more. Moreover, as for the compounding ratio of the raw material of the inorganic component which forms an organic inorganic hybrid material, 70 mass% or less is preferable. More preferably, it is 60 mass% or less. It is excellent in stability of a coating liquid as the mixture ratio of the raw material of an inorganic component is 70 mass% or less, and the fall of transparency of the hardened layer 42 is suppressed.

  The thickness of the cured layer 42 made of the organic-inorganic hybrid material is preferably 10.0 μm or less from the viewpoint of suppressing absorption of infrared rays and securing flexibility. More preferably, it is 5.0 micrometers or less, More preferably, it is 3.0 micrometers or less. Moreover, it is preferable that it is 0.2 micrometer or more from a viewpoint of suppressing the functional fall (deterioration) of the metal layer 18, and being excellent in abrasion resistance. More preferably, it is 0.3 micrometer or more, More preferably, it is 0.5 micrometer or more.

  Here, in the heat shield cloth according to the present invention, the glossiness of the metal layer of the heat shield laminate may deteriorate the appearance of the product when viewed from the heat shield laminate side of the heat shield cloth. Therefore, it is preferable to set the reflection haze of the thermal barrier laminate within a predetermined range. Specifically, the reflection haze of the heat shield laminate is preferably 11% or more. More preferably, it is 15% or more, more preferably 20% or more. The reflective haze of the thermal barrier laminate is measured in accordance with JIS K7361.

  The reflective haze of the thermal barrier laminate can be adjusted by providing asperities on the surface of the outermost layer of the thermal barrier laminate when viewed from the side of the thermal barrier laminate of the thermal barrier cloth. Examples of the outermost layer of the thermal barrier laminate include a resin film 20 and a cured layer 42.

  The formation method of the unevenness is not particularly limited. As a method of providing unevenness on the surface of the resin film 20, a mold transfer method may be mentioned. As a method of providing unevenness on the surface of the hardened layer 42, a mold transfer method, a method of blending particles for roughness formation, etc. may be mentioned.

  When forming the unevenness on the hardened layer 42, it is preferable to increase the difference between the maximum thickness and the minimum thickness of the hardened layer 42 from the viewpoint of setting the reflection haze of the thermal barrier laminate within a predetermined range. Specifically, the ratio (Δ% = (a−b) / a × 100) of the difference Δ between the maximum thickness a and the minimum thickness b of the hardened layer 42 to the maximum thickness a of the hardened layer 42 is 4% or more Is preferred. More preferably, it is 5% or more, more preferably 10% or more. The measurement of the maximum thickness and the minimum thickness of the hardened layer 42 can be performed by observing the cross section of the heat shield laminate. Under the present circumstances, cross-sectional observation of arbitrary five places of a thermal insulation laminated body is performed, and (DELTA)% is represented by these average values. The maximum thickness and the minimum thickness of the hardened layer 42 are the maximum thickness and the minimum thickness within an arbitrary range of 40 μm × 30 μm.

  When the particles for roughness formation are blended in the hardened layer 42 to provide unevenness on the surface of the hardened layer 42, as the particles for roughness formation, microbeads made of resin particles are preferable. In this case, in order to mix micro-order roughness forming particles in the hardened layer 42, the thickness of the hardened layer 42 becomes thick. In this case, the heat insulation is reduced. Therefore, in this case, as a curable material for forming the cured layer 42, a curable resin is preferable to an organic-inorganic hybrid material from the viewpoint of suppressing a decrease in heat insulation.

  When the particles for forming roughness are mixed in the hardened layer 42, as shown in FIG. 9, the ratio (Δ% =%) of the difference Δ between the maximum thickness a and the minimum thickness b of the hardened layer 42 to the maximum thickness a of the hardened layer 42 It is preferable that (ab) / a × 100) is 85% or less. More preferably, it is 80% or less, more preferably 70% or less. Thereby, the detachment of the roughness forming particles 48 to be blended in the hardened layer 42 can be suppressed. The maximum thickness a of the hardened layer 42 is the thickness of the hardened layer 42 in the portion where the roughness forming particles 48 exist, and the minimum thickness b of the hardened layer 42 is the hardened layer in the portion where the roughness forming particles 48 are not present 42 thick.

  From the viewpoint of setting the reflection haze of the thermal barrier laminate within a predetermined range, the roughness-forming particles 48 to be blended in the hardened layer 42 preferably have an average particle diameter in the range of 3.7 to 4.5 μm. . The average particle size of the roughness forming particles 48 is measured by a laser diffraction particle size distribution measuring device. The blending amount of the roughness-forming particles 48 is preferably 3.0 parts by mass or more with respect to 100 parts by mass of the main agent of the cured material, from the viewpoint of reflection haze. More preferably, it is 5.0 parts by mass or more. In addition, from the viewpoint of reflection haze, 15 parts by mass or less is preferable with respect to 100 parts by mass of the main agent of the curing material. More preferably, it is 10 parts by mass or less.

  As mentioned above, although embodiment of this invention was described, this invention is not limited at all to the said embodiment, A various change is possible within the range which does not deviate from the meaning of this invention.

  For example, in the heat shield cloth 10 shown in FIG. 1, both a barrier layer and a hardened layer may be added. Moreover, in the heat shielding cloth 30 shown in FIG. 5, both a barrier layer and a hardened layer may be added.

(Bending, peeling)
The heat shielding cloth (width 30 mm × length 60 mm) produced on a core bar (φ 20 mm) for a roll screen was wound with the fabric (non-woven fabric) side facing outside, and then the winding was unwound. After repeating this winding operation 1000 times, the heat shielding cloth is spread, and the surface on the side of the heat shielding laminate is visually observed, and a bent portion is generated or a peeled portion is generated in the cloth (nonwoven fabric), Examined. In the heat-shielding cloth, when a streak mark indicating a bent portion is observed in a direction perpendicular to the winding direction is regarded as "x" inferior to the bending resistance, and when a streak mark is not observed, the bending resistance is excellent. It was "○". In the heat-shielding cloth, when bubbles (floating) indicating a peeling site appearing when peeled between the adhesive layer and the cloth (nonwoven fabric) are observed, it is regarded as “X” which is inferior to peeling resistance, The case where "was not observed" was made into "(circle)" which is excellent in peeling resistance.

Then, when unrolling, the surface on the side of overlapping thermal barrier laminate and the surface on the side of fabric (nonwoven fabric) adhere and do not peel off when it is "X" to block and the surface on the side of overlapping thermal barrier laminate and fabric (nonwoven fabric The case where it did not adhere with the surface of the side) was made into "○" which does not block.

(water resistant)
The fabric surface of the produced heat-shielding cloth was faced up, and it put into a constant temperature and humidity chamber (60 degreeC90% RH). The presence or absence of corrosion of the Ag-Cu alloy layer was observed with a microscope by time-dependent change. The case where the corrosion of the Ag-Cu alloy layer was not confirmed in the aging over 720 hours after the introduction into the constant temperature and humidity chamber is "○", and the case where the corrosion of the Ag-Cu alloy layer was confirmed is "×" It was evaluated.

(appearance)
The surface of the heat-shielding laminate side of the produced heat-shielding cloth was visually observed. The case where the glare due to the metal layer is strong is evaluated as "C", the case where the glare due to the metal layer is weak is evaluated as "B", and the case where there is no glare due to the metal layer is evaluated as "A".

Moreover, the bending resistance, the reflection haze, the infrared reflectance, and the heat transmission coefficient were measured for the produced laminates (1) and (2). Furthermore, about the produced laminated body (2), the largest thickness a of a hardened layer, the minimum thickness b, and (a-b) / a were measured. In the measurement of optical properties, a 25 μm thick acrylic adhesive sheet (“5402” manufactured by Sekisui Chemical Co., Ltd.) is attached to the upper surface of the Ti oxide layer of laminates (1) and (2). The adhesive layer was used which was attached to one side of a 3 mm thick float glass. The measurement light was made to enter from the laminate (1) (2) side.

(Boughness)

  Table 1 shows the layer configurations and the evaluation results of the heat shield laminate and the heat shield cloth.

  In Comparative Example 1, the degree of penetration of the adhesive layer into the fabric is too low, so it is easy to peel off. In Comparative Example 2, blocking occurs because the degree of penetration of the adhesive layer into the fabric is too high. In Comparative Example 3, since the permeability of the adhesive layer to the fabric is too low, it is easy to peel off. On the other hand, in the examples, the degree of penetration of the adhesive layer into the fabric is within the specific range, and bending and peeling of the fabric are suppressed. Also, no blocking has occurred. And in the structure which has a thermoplastic resin layer, it is excellent also in water resistance. In addition, as the permeability of the adhesive layer to the fabric increases, the stiffness of the thermal barrier cloth also tends to increase, but since the permeability of the adhesive layer to the fabric falls within the specific range, Flexibility is secured.

  And from the example, unevenness is formed on the surface of the hardened layer which becomes the outermost layer of the heat shielding cloth on the side of the heat shielding laminate, and the difference between the maximum thickness a and the minimum thickness b with respect to the maximum thickness a of the hardened layer ( When the ratio of a-b) is 4% or more, the reflection haze is 11% or more, the glossiness due to the metal layer is suppressed, and the appearance deterioration of the product is suppressed. And in an Example, it turns out that it is excellent in thermal insulation, heat insulation, and pliability.
