補強効果が十分でないという欠点があった。[Background Technique 1] As a method of reinforcing an inorganic board, a resin liquid is sprinkled on the surface of a green sheet created by paper-making souffle, and then the resin liquid is sucked into the inside of the green sheet by suctioning from the back side of the green sheet. However, in the conventional method, the 01 fat solution does not uniformly impregnate the inside of the inorganic board. A large amount of resin liquid becomes unevenly distributed, causing variations in the impregnated state.
The drawback was that the reinforcing effect was not sufficient.

Green sheet 2 is made by paper-making cement slurry prepared by mixing and dispersing fibers such as lath fibers in water.9I
The paper-formed green sheet 2 is placed on a felt 1 which is continuously driven to rotate as shown in FIG. 1 and is conveyed. A plurality of suction boxes 6.6 are arranged on the F side of the felt 1 in the conveying direction. Next, the resin liquid 3 is sprayed onto the green sheet 2 from a sprayer 5 such as a brush coater or a sprayer. As the resin liquid 3, an acrylic emulsion having good permeability into the inside of the green sheet 2 can be used. Next, after covering the green sheet 2 coated with this resin liquid 3 with an impermeable film 4, suction is performed using a suction box 6 disposed on the lower surface of the green sheet 2, and the inside of the green sheet 2 is vacuumed. The excipient 7 is produced by dehydrating the water. The impermeable film 4 preferably has a thickness of about 10μ to (1.5a+m) so as to adhere well to the surface of the excipient 7, and a film with good mold releasability such as polyethylene, polypropylene, Teflon, polyester, etc. is used. After the dehydration is completed, the film 4 is peeled off from the surface of the excipient 7, and then the excipient 7 is cured and cured to obtain an inorganic plate.

化して無機質板を補強することになるのである。Then, by covering the surface of the green sheet 2 with the resin liquid 3 sprinkled thereon and sucking it from the back side, the film 4 is brought into close contact with the surface of the green sheet 2. The moisture inside the green sheet 2 is uniformly dehydrated from the back side, and the resin liquid 3 on the front surface is sufficiently impregnated into the inside of the green sheet 2. That is, when the surface of the green sheet 2 is sucked with the film 4 covered, the reduced pressure inside the green sheet 2 becomes approximately equal on the front and back sides, and the reduced pressure state on the front surface of the green sheet 2 and the reduced pressure state on the back surface of the green sheet 2 become approximately equal. There is no large difference in the reduced pressure state, the resin liquid 3 is not unevenly distributed on the back side of the green sheet 2, and the impregnation state of the resin liquid 3 becomes uniform. Furthermore, since the film 4 is closely attached to the surface of the green sheet 2, there is no possibility that the resin liquid 3 will be unevenly dried by air during dehydration. In addition, by using a thin film as described above as the film 4, it will adhere to the surface of the green sheet 2 without any gaps, and by using a film with good mold releasability such as polyethylene, the film 4 can be The resin liquid 3 does not adhere to the film 4 when it is peeled off from the surface of the excipient 7. When the excipient 7 is subsequently dried, the resin liquid 3 inside hardens and reinforces the inorganic plate.

ができる利点がある。Table 1 [Effect of the invention 1 As described above, the present invention sprays a resin liquid onto a green sheet, then coats the green sheet with a film, and then dehydrates the top surface of the green sheet. By evenly dehydrating the water inside the sheet, the resin liquid can be uniformly impregnated inside the green sheet, and the strength of the inorganic board can be increased due to the reinforcing effect of the resin. It has the advantage of increasing water resistance and improving frost damage resistance. Furthermore, it is possible to impregnate the inside of the green sheet with a resin liquid while the surface of the green sheet is covered with a film, which has the advantage that the appearance of the surface can also be improved.
