（例えば、特開平４−４７９０５号公報参照）。2. Description of the Related Art Conventionally, there is a winding method as a method of manufacturing a building board. In this method, a thin slurry is adhered to a felt traveling in a certain direction by papermaking or the like, and the thin slurry is wound around a making roll in a layered manner until a predetermined number of layers are formed, and then the layered slurry is cut in a width direction. Then, a raw plate is formed by peeling the raw plate from the making roll, and the raw plate is cut into a predetermined size, and then cured to obtain a plate member having a predetermined shape (see, for example, JP-A-4-47905). ).

報参照）。However, when the slurry is wound around the making roll in a layered manner, peeling is likely to occur between the layers, and there is a limit to the thickness of the plate that can be made due to the difference in inner and outer diameters at the time of winding. Therefore, as a flow-on type manufacturing method of manufacturing a raw plate without using a making roll, a sheet having a water permeability that circulates a high-concentration slurry containing a reinforcing fiber and having a solid concentration of about 25% in a certain direction. There has been proposed a method in which a single layer and a desired thickness are supplied all at once, and the slurry is dehydrated under reduced pressure by suction means provided on the lower surface of the sheet (for example, see Japanese Patent Application Laid-Open No. 4-153004).

を向上するのが困難となる問題があった。However, the slurry used in the above-mentioned production method has a higher water content than, for example, an extrusion molding method or a dry method, and therefore, a suction / dehydration step of excess moisture in the molding process is indispensable. . By the way, in the suction dewatering of the cement slurry, the slurry layer is, for example, 1
When the thickness of the layer is 0 mm or more, the fluidity of the water in the matrix deteriorates. Therefore, in order to dehydrate by suction to a desired moisture content, the suction force of the dehydration device is increased and the transfer speed of the forming belt is also reduced. There has been a problem that the necessity arises and it is difficult to improve the productivity.

Further, at the time of suction dehydration, alkaline wastewater is generated. However, there is a problem that the thinner the slurry or the thicker the layer, the larger the amount of wastewater and the larger the wastewater treatment equipment. On the other hand, decorative building materials include printed plywood, polyester plywood, and painted plywood, all of which have a thin decorative portion and are inferior in solid feeling and three-dimensional appearance, and are also inferior in terms of frost damage resistance, weather resistance, and the like.

In addition, the method of the present invention is based on a manufacturing method in which the slurry 7 is supplied in a layered manner on the forming belt 1 on which the dewatering device 6 is disposed on the back surface and stratified by suction dehydration. Inorganic materials such as cement, silica sand and fly ash, inorganic lightweight aggregates such as pearlite, reinforcing fibers, and the like are the same as conventionally known materials, and there is no particular point in the types of these compounding materials themselves.

Accordingly, the slurry 7 is suction-dewatered from the back surface, and the dried cosmetic powder 9 is dried from the front surface.
Since the water is absorbed by the compound of the formula (1), drainage is reduced, and the load of the suction dewatering device from the back of the forming belt is reduced accordingly.

It can be used as an interior finishing material with high feeling, three-dimensional appearance and weather resistance. Further, the flow of water in the direction of the back surface during suction dehydration is also reduced, so that it is difficult to form a water supply that traverses the layer, and the improvement of the water supply of the plate material is prevented. Further, since the composition of the cosmetic powder having a dried surface is pressed by a roll or the like and absorbs water, it is hardened by the water and integrated with the slurry layer.

粧建材１６を製造できた。Therefore, the cement composition of the lightweight inorganic building material is a composition comprising 47% by weight of cement, 47% by weight of silica as silica, 5% by weight of pulp fiber, and 1% by weight of expanded polystyrene particles, and water is added thereto. A slurry 7 having a water concentration of 50% to 70% is adjusted step by step, and the slurry 7 is supplied in a layered manner by a supply device 8 onto a forming belt 1 which moves at a constant speed and has a dewatering box 5 arranged on the back surface. Then, from the position immediately after that, a dry decorative powder 9 such as a colored cement powder, a colored silica sand, and a hydraulic powder containing an inorganic pigment is sprayed and supplied to the surface of the slurry layer 7A by two-stage supply devices 10A and 10B in this embodiment. Then, the slurry layer 7A and the heat insulating layer 9A are dewatered while being pressed by the pressing means 11 to form a band-shaped raw plate 13, and the raw plate 13 is cut into a predetermined size and cured. As a result, as shown in FIG. 1 (B), the inorganic layer 14 hardened by dehydrating the slurry and the decorative layer 15 made of dried cosmetic powder and hardened by absorbing the water in the slurry were integrated. The decorative building material 16 rich in solid feeling and the like could be manufactured.

Since water is absorbed, the amount of water to be sucked and dewatered is reduced by that amount, and the amount of drainage is reduced, and at the same time, the load on the suction and dewatering device is reduced, so that devices such as a drainage purification device and a molding device can be reduced. Furthermore, even if the thickness of the inorganic layer to be formed is large, sufficient suction dehydration can be performed with a small load, and the matrix can be in a finely packed state, and a decorative building material having excellent strength can be molded with high productivity. It also has effects such as.
