るものではなかった。BACKGROUND OF THE INVENTION As a noncombustible molded article, for example, inorganic paper whose main raw material is inorganic fiber is known. When producing high-temperature paper like this, the fibers are made using a paper machine using a binder.There are two types of binders, organic and inorganic, but it is difficult to manufacture paper using only inorganic binders. It lacks adhesive strength and is difficult to manufacture, requiring the combined use of an organic binder. Inorganic paper manufactured using an inorganic binder is 500
The organic matter must be incinerated by firing at ~800°C, but in this case, there is a problem that the strength of the resulting inorganic paper is not sufficient with only the remaining inorganic binder. Furthermore, this problem is not limited to inorganic paper, but also applies to molded bodies made of other inorganic fibers. As a method for producing a sheet-like product made only from inorganic fibers, a method using sepiolite mineral staple fibers as a binder is known, but the strength of the sheet-like product obtained in this case was also not sufficiently satisfactory.

Although it is preferred that the clay powder is completely dissolved in the water, it is not necessary that all the clay powder be dissolved in the water as long as the clay powder is uniformly dispersed in the water. Therefore, the dispersion solution in the present invention refers to both a solution in which the clay is completely dissolved in water and a solution in which the clay is uniformly dispersed in the solution without being partially dissolved.

At this time, if necessary, use alumina sol,
Addition of inorganic substances such as silica sol, zirconia sol, sodium phosphate, bentonite, cordierite, zeolite, magnesia, and yttria improves the heat resistance of the resulting molded product. The amount of these additives is preferably 10 to 100 parts by weight per 100 parts by weight of clay powder.

Next, this molded body is preferably heated to 40
Drying at ~120°C for 1 to 5 hours yields the desired nonflammable molded product. This molded body is more preferably 800~
When fired at 1200°C, organic substances and impurities contained in the clay are removed, and inorganic substances in the clay are sintered, improving heat resistance. In this case, even if the organic matter is removed, the shape is retained by the clay.

Next, 2 parts by weight of Himoroc (trade name, manufactured by Kyoritsu Organic Co., Ltd.) as a polymer flocculant was added to this fiber dispersion to coagulate the fibers, and then the fibers and water were separated, and a paper towel with a thickness of 0 .4mm paper was produced. This was cut into 20 mm width x 200 mm length, and the tensile strength was determined. Table 1 shows the physical properties and strength test results of this paper.
