2. Description of the Related Art Conventionally, as a sash for windows, a joint material or a corner material for walls, in order to give a high-class feeling to buildings,
There is known a building material made of stainless steel or the like which is formed into a predetermined cross-sectional shape by a method such as roll forming, hot extrusion and bending. However, these stainless steel building materials and the like have the drawbacks that they are expensive, the manufacturing equipment is expensive, the cross-sectional shape is restricted, and the weight is heavy and the handling is inconvenient as compared with the aluminum materials. Further, in the case where these stainless steel building materials and the like are required to have brilliance, polishing by secondary processing is required.

Recently, as an inexpensive and lightweight building material or the like, a laminated material having a resin surface coated with a stainless steel foil has been commercially available. Such a laminate material is obtained by applying a hot melt adhesive to one surface of a commercially available stainless steel foil having a thickness of about 100 to 200 μm, and applying polyvinyl chloride (PV
It is manufactured by extruding a resin such as C), and is substantially made of a resin whose surface is covered with a stainless foil.

However, in the above-mentioned conventional laminating material, since the resin such as PVC as the base material and the adhesive used are relatively soft, when the stainless steel foil on the surface is scratched or hit with a hard material, There was a drawback that the stainless steel foil was dented on the substrate side and the surface was easily dented and scratched.

In addition, a thickness of 100 to 200 μ which is generally commercially available
The stainless steel foil of about m has a low glossiness, and it is difficult to further polish the thin foil even in manufacturing, so when using a base material such as a building material,
It was not possible to give a sufficient high-class feeling to the obtained covering structural material.

[0006]

In view of such conventional circumstances, the present invention is excellent in brilliance, rich in luxury, lightweight, easy to handle, and high when adhered to the surface of a structural material such as a building material. It is an object of the present invention to provide a glittering laminate material which is hard to be dented or scratched on the surface because a surface hardness can be obtained, and a covering structural material in which a building material or the like is coated with the glittering laminate material.

[0007]

In order to achieve the above object, the glitter laminate material of the present invention has a thickness of 30 to
A glittering stainless steel foil with a gloss of 800 or more at 120 μm and a thickness of 25 to 10 adhered to one side of the glittering stainless steel foil with a urethane or acrylic adhesive layer having a thickness of 2 to 30 μm.
And a thermoplastic polyester resin layer having a thickness of 0 μm.

Further, in the glittering laminate material of the present invention, the Vickers hardness on the surface of the glittering stainless steel foil is preferably 180 to 320.

Further, the coated structural material of the present invention has a structure in which the above-mentioned glitter laminate material is bonded to the surface of a base material made of an aluminum alloy by using an adhesive.

[0010]

[Function] The glittering stainless steel foil used in the present invention has a glossiness of 800 or more (JIS Z 8741 Gs 45 °), and is manufactured by rolling a relatively thick stainless sheet to a thickness of 120 μm or less by rolling only once. it can. Therefore, the thickness of the glitter stainless steel foil is to obtain the glitter with a glossiness of 800 or more.
In addition, it must be 120 μm or less so that it can be easily deformed according to the shape of the structural material when it is bonded to the structural material, and if it is less than 30 μm, it will be wrinkled during molding or bonding to the structural material because it is too thin. Because it is difficult to handle, such as easy
The range is 30 to 120 μm.

Further, the hardness of the above-mentioned glitter stainless steel foil is preferably in a range of 180 to 320 in Vickers hardness (H _V ). The reason is that if the Vickers hardness is less than 180, 1
It is difficult for the foil obtained by rolling once to have a gloss of 800 or more, and if the Vickers hardness exceeds 320, springback will occur when molding according to the shape of the aluminum alloy base material, and the adhesive strength with the base material will increase. This is because it is lowered or the adhesion becomes difficult. The surface of the stainless steel foil may be subjected to hairline processing or etching processing to enhance the decorative effect.

In the glitter laminate material of the present invention, as shown in FIG. 1, a thermoplastic polyester resin layer 3 is adhered and fixed to one surface of a glitter stainless steel foil 1 with a thin urethane or acrylic adhesive layer 2 interposed therebetween. It is manufactured by
The glitter laminate material 4 is usually supplied in the form of a tape or a sheet, and is molded in accordance with the shape of the aluminum alloy substrate 5 such as a sash as shown in FIG. It is attached and provided as a covering structural material such as an aluminum sash having excellent surface gloss.

The thermoplastic polyester resin used for producing the glitter laminate material 4 can be easily thinly formed, and even if it is thin, it has excellent mechanical properties such as strength and hardness as compared with other resins. . Therefore, by fixing the thermoplastic polyester resin layer 3 to the glitter stainless steel foil 1, the glitter laminate 4 obtained can be made to have an appropriate thickness to improve handleability, and the glitter laminate 4 has a high surface. Hardness is imparted. As a result, if the glitter laminate 4 is adhered to the aluminum alloy base material 5 and used as a covering structure material such as a building material, the glitter stainless foil 1 can be used even if the surface is scratched or hit with a hard object. It is hard to get dents and scratches on its surface, is tough and durable, and can retain its luster for a long time.

Another reason for using the thermoplastic polyester resin layer 3 is a problem regarding corrosion when it is used by being adhered to the aluminum alloy base material 5. That is, when two kinds of metals having different ionization tendency are present in contact with each other in a corrosive environment, corrosion of the metal having a lower potential proceeds,
When stainless steel and aluminum or their alloys are in contact with each other, aluminum or its alloys are more corroded.
Therefore, in the present invention, in order to avoid contact between the aluminum alloy base material 5 and the bright stainless steel foil 1, the thermoplastic polyester resin layer 3 is interposed therebetween.

The reason why the thickness of the thermoplastic polyester resin layer 3 is 25 to 100 μm is that the strength is lowered when the thickness is less than 25 μm and the elastic deformation tends to occur when the thickness exceeds 100 μm.
This is because in any case, the surface of the glittering stainless steel foil 1 is likely to be dented or scratched by scratching or hitting, so that substantially high surface hardness cannot be obtained. As the thermoplastic polyester resin, polyethylene terephthalate (PET) -based or polybutylene terephthalate (PB) is used.
The T) type resin is particularly preferable.

The adhesive layer 2 for adhering and fixing the glittering stainless steel foil 1 and the thermoplastic polyester resin layer 3 must be capable of adhering to the polyester resin and have a high hardness after curing. An acrylic adhesive is used. The thickness of the adhesive layer 2 needs to be 2 μm or more in order to obtain an adhesive strength of 1 kg / cm or more, which is usually required as a structural material such as a building material. The surface hardness of the glittering stainless steel foil 1 is lowered, and when it is adhered to the aluminum alloy base material 5 to form a coating structure material, the surface of the glittering stainless steel foil 1 is likely to have a dent or scratch. .

Next, the aluminum alloy is used as the base material of the coated structural material of the present invention because it is lightweight and hardly rusts, and it is extremely easy to form various structural materials into a predetermined sectional shape. Of these, an Al-Mg-Si-based (6063-based) alloy used for ordinary extruded shapes is preferable. The aluminum alloy base material 5 is a bright stainless steel foil 1.
It is preferable to apply alumite treatment from the viewpoint of adhesive strength with and its durability, and the film thickness of alumite treatment is 6μ
It is preferably m or more.

Further, the adhesive 6 for adhering and fixing the glittering laminate material 4 to the surface of the aluminum alloy base material 5 needs to be capable of adhering to the aluminum alloy and the thermoplastic polyester resin. An epoxy-based, urethane-based, acrylic-based, or polyester-based adhesive is appropriately selected and used according to the cross-sectional shape of the material, the bonding processing method, the use of the covering structural material, and the like. The thickness of the adhesive 6 is not particularly limited, and may be the same as in the case of adhering a coating material of stainless steel or aluminum in the manufacture of a coating structural material of this type such as a building material conventionally.
