板１に積層してなる折板屋根材料である。 Traditionally, folded-plate roofing materials have been made by pasting a heat insulating material on the back side of a metal plate, and various types of such heat insulating materials are known, one of which is inorganic fiber whose main component is rock wool. A sheet-like product is known that is wet-formed using a thermoplastic emulsion as a binder (Utility Model Publication No. 41376/1983). Such a heat insulating material is considered to be preferable as a heat insulating material for folded-plate roofing materials because it has dew condensation prevention properties and non-combustibility, but it has not yet been put to practical use. The reason for this is that when forming a sheet using the normal wet method, the constituent fibers are arranged in layers, and the binder distribution within the sheet layer is uneven, resulting in an insufficient amount of binder in the intermediate layer of the sheet (in this case, the amount of binder (Increasing the amount of heat will compromise the nonflammability of the sheet), so the interlaminar strength of the sheet is weak, and when laminated to metal plates and folded, the inorganic fibers will be damaged and cracks will occur in the sheet.
An example of this is that it does not have satisfactory folded plate workability. In order to improve the interlaminar strength of the sheet, we created carded webs from inorganic fibers such as glass fibers.
It is also known to use a needle-punched sheet, but even with this method, the interlayer strength of the sheet is insufficient, and the problem of interlayer peeling of the sheet occurs during folded plate processing. (Unexamined Japanese Patent Publication No. 52-149829
In order to eliminate these conventional drawbacks, the inventors of the present invention have conducted intensive studies on improving the folding processability of sheets made of inorganic fibers, that is, improving the interlaminar strength of sheets. The present invention was achieved based on the discovery that, by selecting a suitable binder, the degree of orientation of the constituent fibers of the sheet can be increased within the sheet layer, and the binder distribution can be made uniform, thereby achieving the object. In other words, the present invention is a)
Non-combustible fibrous material mainly composed of rock wool 80
~97% by weight and b) 3 to 20% by weight of a binder whose main component is a thermoplastic resin, wherein a) the degree of orientation of the fibrous material in the layer of the sheet is 31 to 80. b) A folded plate formed by laminating a sheet-like material 2 on a metal plate 1, in which the binder content in the middle layer of the sheet-like material is 2% by weight or more and 0.25 times the average value of all the layers. It is a roofing material.

are laminated through. Since the feature of the folded plate roofing material of the present invention lies in the sheet-like material, the sheet-like material will be explained first.

よい。 The non-combustible fibrous material constituting the sheet-like material of the present invention may be made of rock wool as a main component, with small amounts of asbestos, inorganic fibers such as glass fiber, alumina fiber, or carbon fiber added as necessary. . Further, in some cases, a part of the nonflammable fibrous material may be replaced with organic fibers such as cellulose and vinylon within a range that does not reduce the fire resistance.

げることができる。 In the sheet-like product of the present invention, as the binder for adhering the fibrous substances to form the sheet, it is necessary to use a binder whose main component is a thermoplastic resin from the viewpoint of the flexibility of the sheet. Examples of such resins include polyvinyl alcohol, polyacrylic acid, ethylene-vinyl acetate copolymer, plasticized vinyl chloride-vinyl acetate copolymer, polyurethane, (meth)acrylic acid ester copolymer, and the like.

なると屋根材として必要な不燃性が不充分とな
る。 The ratio of fibrous material to binder in the sheet material is 80 to 97% by weight of fibrous material and 20% by weight of binder.
~3% by weight is required. If the binder amount is less than 3% by weight, the binder content is too small and the strength and flexibility required for laminating it on metal plates are unsatisfactory.On the other hand, if the binder content is more than 20% by weight, the binder content is too low and the strength and flexibility required for lamination on metal plates are unsatisfactory. Sexuality becomes insufficient.

% by weight or more and 0.25 times the average value of all the layers is used. By doing so, the interlayer strength of the sheet is increased and it can withstand folding plate processing, and a small amount of Since the binder is effectively used, the non-combustibility of the sheet material is ensured. Also, due to the high fiber orientation,
The density of the sheet-like material becomes low, and a lightweight material can be obtained. Here, the degree of orientation of the sheet-like material is a value determined by the following method.

以上にしておく必要がある。 The front and back surfaces of the sheet-like material of a predetermined size are bonded to a flat metal plate using an adhesive. Next, the upper and lower metal plates are grasped with a chuck, and the crosshead is raised at a constant speed to cause the sample to break. By doing the usual interlaminar fracture strength measurement, the sheet-like material can be measured using the nonflammable fibrous material in the layers. Cutting occurs from the oriented layered interface. The degree of orientation is determined by measuring the angle between the metal flat plate surface of the fractured test piece and the fracture surface. In a rock wool sheet obtained by the conventional wet papermaking method, the degree of orientation obtained by the above-mentioned measurement method is substantially 0, and the interlaminar strength is weak because the constituent fibers are aligned in the plane direction. In addition, a bracket-shaped insulation material for piping is also commercially available, which is made by cutting rock wool layered cotton into a certain length and pasting them together with the cut ends aligned so that the cut length corresponds to the thickness (that is, the degree of fiber orientation is 90 degrees). However, although such a heat insulating material has high flexibility, there is a problem in that its strength in the plane direction is too low, making it unsuitable as a sheet-like material for use in folded-plate roofs. Further, the amount of binder in the intermediate layer of the sheet-like material is a value determined by the following method. Diameter 20 to 50 centered on any point on sheet material A
After punching several mm cylindrical test specimens, each test specimen was further cut into n layers (n = 3 to 8) parallel to the surface so that the thickness was uniform. Number them from 1 to n. Here, 1 and n
corresponds to the surface layer, and 2 to n-1 correspond to the intermediate layer. The samples were left in a desiccator at room temperature for a day and night, and then placed in separate porcelain crucibles at 550 to 600 ml.
The weight loss of the m-th layer when baked in an electric furnace at ℃ for 30 to 60 minutes is taken as Am weight %, and the weight loss of the m-th layer is calculated in the same way for sheet B produced without using the binder at all. When the weight loss of m layer is Bm,
The amount of binder in the m-th layer can be determined as Xm=Am-Bm. When the organic content in the sheet-like material is only the binder, it may be determined as Xm=Am for convenience. The amount of binder in the entire sheet-like material is an average value of 1 to n, and the amount of binder in the intermediate layer is determined as an average value of 2 to n-1. The amount of binder in the sheet intermediate layer must be at least 2% by weight from the viewpoint of folding plate processability. Furthermore, even if the concentration is 2% by weight or more, if there is too much deviation between the surface layer and the surface layer, the intermediate layer is likely to be destroyed.
The amount of binder in the middle layer must be at least 0.25 times the average value of all layers.

し、一体成形することも有効である。 Such a sheet-like product is usually formed by a papermaking method, and an example of its manufacturing method is to prepare a slurry stock solution by dispersing a nonflammable fibrous material such as rock wool together with a binder in water. The thermoplastic resin used as the binder is preferably water-soluble, emulsion, or latex. Furthermore, as mentioned above, in order to improve the binder distribution within the sheet layer, crosslinking agents for thermoplastic resins (isocyanate compounds, zirconia compounds, etc. are used for polyvinyl alcohol, polyvinyl acetate, polyacrylic acid ester emulsions, It is preferable to add a small amount of a modified polyamideimide epoxy resin, isocyanate emulsion, etc.) or a polymer flocculant (polyacrylamide, polyethyleneimine, sodium polyacrylate, etc.). The obtained slurry stock solution is supplied to the surface of a moving or rotating net-like or porous base material and formed into a sheet. In this case, the angle between the slurry stock solution and the surface of the base material is set at 5 to 60 degrees. (preferably 20 to 45 degrees) and blowing fluid into the slurry stock solution on the base material surface so as to cause turbulence to the slurry stock solution when the slurry stock solution is paper-formed on the base material surface. The weight is important in obtaining a sheet-like product having the above-mentioned degree of orientation. The obtained sheet-like material is dehydrated under reduced pressure, dried, and used for lamination with metal plates. Sheet materials are usually 0.5 thick
~50 mm and apparent density in the range of 0.04 to 0.2 g/cm 3 are produced. In the production of the above-mentioned sheet-like product, it is preferable to add a flame retardant to further improve the nonflammability of the sheet-like product. A particularly preferred flame retardant is a combination of 5 to 50 parts by weight of an antimony compound (such as antimony trioxide) and 10 to 100 parts by weight of an aromatic bromine compound (such as pentabromomethylbenzene) based on 100 parts by weight of the binder. Can be mentioned. Further, in order to further improve the strength of the sheet-like article, it is also preferable to add a reinforcing material to the intermediate layer or surface of the sheet-like article. As the reinforcing material, various films, metal foils, etc. are suitable for improving moisture proofing/waterproofing properties, and cloth, paper, nonwoven fabrics, etc. are used when moisture permeability/hygroscopicity is required. In addition, in order to prevent itching (skin irritation caused by adhesion to the human body) caused by fibrous substances such as rock wool, we apply a dispersion of organic fibers (pulp, regenerated cellulose, synthetic fibers, etc.) to the surface of the sheet during papermaking. It is also effective to combine the formed sheets and integrally mold them.

It can also be obtained by laminating. As shown in FIGS. 2 and 3, such roofing materials can be joined adjacently by a seam method or an overlapping method to form a fire-resistant roof structure. Figure 2 shows a cross-sectional view of the joint part of a roof structure in which a composite plate-like material in which metal plates and sheet-like materials are laminated is folded into a predetermined shape and then joined adjacently by the seam method. FIG. 3 shows a cross-sectional view of a joined portion of roof structures that are joined adjacently by the overlapping method using tightening bolts 4.

ある。 By configuring the present invention as described above, damage to the sheet during processing of folded plates (cutting of fibers, occurrence of sheet cracks), which was a problem with conventional inorganic fiber sheets, is eliminated, and the roll pressure during processing is reduced. The restoring force of the sheet-like material is sufficient even when the sheet-like material is affixed to a metal plate, and then the folding process can be performed efficiently. Furthermore, since the sheet-like material contains only a small amount of binder, it is nonflammable, and the folded plate roofing material thus obtained has excellent noncombustibility, heat insulation, anti-condensation properties, and soundproofing properties.
