照して説明する。 The structure of the heat insulating material of the present invention is as described above, and the sheet-like material has organic fibers mixed between glass fibers with high embrittlement, and the glass fibers or organic fibers are mixed in the thickness direction of the sheet-like material. In addition to being needle-punched, the glass fibers and organic fibers or organic fibers are partially bonded together using the hot-melt adhesive that made up the composite fibers.
It is bulky, has excellent heat insulating properties, has high mechanical strengths such as compressive strength, shear strength, tensile strength, and bending strength, and is resistant to delamination.
In addition, since it uses composite fibers consisting of organic fibers and hot melt adhesive, it is easier to use the above machines than those that mix organic fibers and spread emulsion adhesive or powdered hot melt adhesive. The amount of organic fibers and adhesive added can be reduced without reducing the physical strength, and it has excellent nonflammability. Therefore, when folded after being laminated to a metal plate, the bent part will not be cut, and the valley will not bulge or peel, making it non-flammable according to Ministry of Construction Notification No. 1828, making it suitable for metal folding plates. It is suitable for use as a heat insulating material. Next, the present invention will be explained with reference to examples.
