が好ましい。 Further, in the present invention, the glass fibers of the sheet-like material are partially adhered with an adhesive in which organic fibers are dispersed in the sheet-like material to form a heat insulating material for a metal folding plate. Any conventionally known method may be used for the adhesion, such as a method of spraying an emulsion adhesive onto the sheet material and drying it to solidify it, a method using ethylene-vinyl acetate copolymer, polyethylene, modified polyethylene, modified polypropylene, etc. A method in which 50 to 200 meshes of powder of a hot melt adhesive such as polymerized polyamide, copolymerized polyester, copolymerized polyacrylic, modified polyvinyl alcohol, etc. is sprinkled or mixed onto the sheet-like material and heat-sealed, and the hot melt adhesive described above is applied. Examples include a method in which heat-fusible fibers made from a heat-fusible agent are mixed together when producing a top-pressing sheet-like material, and the obtained sheet-like material is heat-sealed. The above-mentioned heat-fusible fibers include fibers in which a hot-melt adhesive is laminated around the organic fibers, fibers in which organic fibers are dispersed in a sea-island shape in a hot-melt adhesive, and fibers that are heat-fusible with organic fibers.

版用の断熱材として好適に使用される。 As mentioned above, the structure of the heat insulating material for metal folding plates of the present invention is that organic fibers are mixed between highly brittle glass fibers, so it is bulky and has excellent heat insulation properties. It is difficult to break even when compressed or sheared, etc. are applied, and a large number of glass fibers or organic fibers are forcibly arranged in the thickness direction over the entire surface of the sheet, and the glass fibers and organic fibers are partially bonded. As a result, the tensile strength and bending strength are increased, and the layers are less likely to peel off. Therefore, when it is laminated onto a metal plate and then bent, the bent part will not be cut, and the troughs will not bulge or peel, and since it contains 60 to 95% glass fiber by weight, the metal plate When laminated with metal plates, it is nonflammable according to Ministry of Construction Notification No. 1828, and is suitable for use as a heat insulating material for metal folding plates.
