Poor fire resistance. For this reason, a practical flooring material having high strength, light weight, excellent fire resistance, and excellent workability has not been developed so far. By the way, as a building material, gypsum board is excellent in terms of cost, and is used for wall materials and the like. For example, a building material for a wall and a partition in which a prepreg made of a thermoplastic resin is adhered to a gypsum board is disclosed in Japanese Unexamined Patent Publication No. 7-3.

とを目的とする。However, this is not a use as flooring. It was common knowledge in the construction industry that gypsum board could not be used for flooring because of its low strength. The present invention overturns such common sense and uses a porous inorganic core material such as gypsum board for the flooring material, and is an ideal floor having high strength, light weight, excellent fire resistance, and excellent workability. The purpose is to propose materials.

め、軽量で加工性に優れる。[0006] A porous inorganic core material such as gypsum board has low strength against tensile force and high compressive strength. For this reason, when a force is applied to the floor material, a pulling force is generated on the side opposite to the side on which the force is applied, and destruction starts from the point at which this force is generated. The heat-resistant composite flooring material 100 of the present invention comprises a thermosetting resin 1 and an inorganic fiber 2 as shown in FIG. Formed on the surface to prevent breakage even when a pulling force is applied. Therefore, the reinforcing layer 4 needs to be formed at least on the back surface side (the opposite side of the indoor side) of the porous inorganic core material 3. Further, the reinforcing layer 4 may be formed on only one surface of the porous inorganic core material 3 as shown in FIG. 1 or on both surfaces of the porous inorganic core material 3 as shown in FIG. Further, unlike a thermoplastic resin, a thermosetting resin has excellent fire resistance and does not soften even at a high temperature, so that the function as a reinforcing layer is not lost. Further, the fire-resistant composite flooring material 100 of the present invention has a porous inorganic core material 3,
Since it is composed of the thermosetting resin 1 and the inorganic fibers 2, it is lightweight and has excellent workability.

Further, the thickness is desirably 15 mm to 30 mm. The reason is that in this range, sufficient rigidity and impact resistance can be obtained, a sufficient wiring space under the floor can be secured, and high workability is obtained. Alternatively, a plurality of core materials having a thickness of less than 15 mm may be laminated and adjusted to the above-described thickness.

The method of coating the surface of the fiber with a thermosetting resin at the B stage is advantageous because the adhesion to the impregnated resin is improved, the fibers are easily bonded to each other, and the impregnation ratio of the resin can be improved. As a method of such coating, a raw material melt of glass fiber, rock wool, and ceramic fiber is discharged from a nozzle, and fiberized by a blowing method or a centrifugal method. The cotton is collected by spraying the resin solution.
